DOCTORS Hospital plans to launch stem cell therapy and enter the primary healthcare market during its current financial year, after profits for the year to end-January 2017 increased five-fold.

The BISX-listed healthcare provider said it planned to launch both initiatives at its Bahamas Medical Centre facility on Blake Road, having received the necessary approvals for one stem cell programme and another in its final stages.

Doctors Hospitals 2017 annual report did not identify the types of stem cell treatment involved, but said: It is envisioned that stem cell therapy will occur at the facility [Bahamas Medical Centre] in fiscal 2018, with one programme already receiving the necessary approvals and the second programme in its final stages of assessment and approval......

We anticipate that in fiscal 2018 we will launch one of our primary care centres at this location, supported by increased specialist services to best serve the neighbouring communities.

Joe Krukowski, Doctors Hospitals chairman, told shareholders via the annual report that the launch of primary care services will be a vital component in the continuum of care we provide.

We will seek to provide our customers with multiple entry points for this level of care, he added.

Doctors Hospitals stem cell initiatives, in particular, represent a potential boost to the Bahamas national effort to make greater inroads into the medical tourism market while also exploiting legislation passed by the former Christie administration.

The healthcare providers move into primary care will effectively create a fully-integrated model, combining with its core business in secondary and tertiary care provision to potentially make Doctors Hospital almost a one-stop shop for all medical needs.

The expansion comes after Doctors Hospital saw total comprehensive income for the year to end-January 2017 grow by 409 per cent or more than five-fold, from $702,790 to $3.578 million year-over-year.

The growth was driven entirely by the companys main Collins Avenue facility, where profits more than doubled, increasing by 157.4 per cent to $4.778 million compared to $1.856 million the year before. The Bahamas Medical Centres net loss increased slightly compared to the prior year, rising from $1.153 million to $1.2 million.

An improved top-line drove Doctors Hospitals improved profitability, with patient services revenue up $3.65 million or 7.4 per cent at $52.713 million.

Patient days increased by 6 per cent from the previous year, the annual report said of the main Collins Avenue hospital. Increases in the Intensive and Intermediary Care Units accounted for 37per centof the change, and the balance in medical surgical and maternity.

Total admissions to the facility were 4,114 in fiscal 2017 compared to 4,063 in fiscal 2016. The continued flat admission numbers and increased patient days are indicative of the trend toward a rising severity of illness. The average daily census increased to 33 patients per day from 31.2 in the previous year.

Doctors Hospitals total expenses grew by $818,452 or 1.7 per cent year-over-year, with salaries and benefits rising by $1.176 million or 5.6 per cent to $23.209 million. Due to the top-line growth, these fell as a percentage of patient net revenue from 44.3 per cent to 43.5 per cent.

At Bahamas Medical Centre, revenues rose by $28,015 or 1.9 per cent to $1.462 million. This slightly outpaced the increase in expenses, which jumped by 1.5 per cent or $43,479 to $2.819 million as a result of rising medical supplies costs.

Doctors Hospital is budgeting $7 million for capital spending projects in its financial year to end-January 2018, a sum more than double the prior years $3.1 million, as it bids to upgrade facilities and replace equipment.

Bad debt expense, as a percentage of patient service revenues, decreased to 2.6per centfor the year ended January 31, 2017, compared to 3.4per centthe previous year, Doctors Hospital said.This represented a decrease of $316,808, or 18.8per cent. This decrease is a result of a write-off of third-party receivables.

The number of days revenue in accounts receivable at year-end (AR Days) for fiscal 2017 stand at 51 compared with fiscal 2016 at 43 days, and net receivables as a percentage of net patient revenue increased to 14.1per centfrom 11.8per cent. These increases area result of high activity in the months of December and January, and payments not received until after year-end.

Using Stem Cells to Heal Broken Bones – Healthline

June 6th, 2017 11:43 pm

A promising new method for regenerating bones using the body's own stem cells may possibly eliminate the need for bone grafts.

When a fracture will not heal, people are typically left with two options.

One is bone grafting, the other is surgery.

A new treatment that uses gene and stem cell therapies could promise success with a less-invasive procedure.

Researchers led by a team from Cedars-Sinai Medical Center in Los Angeles, tested the therapy on laboratory animals and found that it triggered bones to regrow their own tissue.

If it is found safe in humans, the process could replace bone grafting as the gold standard treatment.

We are just at the beginning of a revolution in orthopedics, Dan Gazit, co-director of the Skeletal Regeneration and Stem Cell Therapy Program in the Department of Surgery and the Cedars-Sinai Board of Governors Regenerative Medicine Institute, said in a statement.

The study was published in the journal Science Translational Medicine.

Bone grafts can result in gaps between fracture edges, and often require surgery to relocate bone from other places in the body to fill in the spaces.

Bone can come from the patient or a cadaver.

But healthy bone isnt always available, and surgeries can lead to other complications.

The new method involves implanting a collagen matrix made up of bone-inducing genes into stem cells.

It is inserted into the gap over a two-week span. An ultrasound pulse and microbubbles help the matrix get into the cells.

Our method relies on the bodys own repair cells [stem cells], Gadi Pelled, senior author, and an assistant professor of surgery at Cedars-Sinai, told Healthline. We recruit them to the injury site and then activate them to regenerate bone in an efficient way.

The uniqueness of our method is that it is injectable and minimally invasive, Pelled said.

Researchers found that the fractures were healed eight weeks after the procedure. The bone that grew into the empty space was as strong as surgical bone grafts.

We showed that our method was equivalent, in terms of fracture healing, to the use of an autograft [bone graft obtained from the patients own body], which is the gold standard today, Gazit said. Our method does not require the harvest of bone, which often leads to prolonged pain and hospitalization and risk of infection, and that is our advantage.

Because the process uses stem cells from the patients body without external manipulation, it may not face many of the hurdles that other stem cell treatments come up against.

But obviously we will need to show that our method is not toxic and is safe to use in people before it is approved for use in the clinic, added Zulma Gazit, PhD, co-director of the Skeletal Regeneration and Stem Cell Therapy Program in the Department of Surgery and the Cedars-Sinai Board of Governors Regenerative Medicine Institute.

In cases where there are large gaps or fractures unable to heal, the method can be repeated to grow more bone.

Thats something that will need to be reproduced in additional studies, but the latest study is the first to show that this ultrasound-mediated gene delivery can be used to treat nonhealing bone fractures, Pelled added.

David Forsh, an assistant professor of orthopedics at the Icahn School of Medicine at Mount Sinai, and chief of orthopedic trauma at Mount Sinai St. Lukes, said the breakthrough needs to be reproduced before it goes mainstream.

Similar research has been conducted in the past, but the way this was done is something new, according to his knowledge.

It sounds good, Forsh told Healthline. Its very promising that they were able to achieve this.

Dr Libby: The nutrients that help support healthy vision – Stuff.co.nz

Our eyesight is such a gift - and we should look after it.

For many people, eye health just isn't a conscious priority new research in Australia indicates that only 6 per cent of people aged between 50 and 64 years rate an eye disease check as their top health priority.

Assuming that New Zealanders have similar health priorities, this is concerning as it has previously been shown that 99 per cent of New Zealanders aged 55 years and over have noticed changes in their vision.

Despite this, only half schedule frequent eye exams, and many are not aware of ways in which they can proactively enhance their eye health, such as through a plant-rich diet full of vision-supporting nutrients.

Did you know that dark green leafy vegetables are considered the best vegetable for great eye health? More than a third of adults surveyed in New Zealand identified carrots as the top vegetable for eye health, while spinach was the top pick for less than one in 20.

Our eyesight is such a gift it allows us to see and appreciate beautiful landscapes, to curl up and enjoy a good book with ease, and to watch our children and grandchildren play and grow up. We often hear about the importance of taking care of other organs, such as our heart, but eye health tends to be less of a focus perhaps due to a perception that declining eyesight and compromised vision are an inevitable consequence of ageing.

I'm not denying that ageing affects the eyes, but science tells us that we can mitigate this process with good nutrition.

Nutrients for great eye health include:

VITAMIN C

The concentration of vitamin C in the fluid in the eye is higher than in any other body fluid. Vitamin C is a potent antioxidant that helps to protect the eyes from damage associated with exposure to environmental factors, and it also enhances nutrient delivery to the eyes by promoting healthy blood vessels. Vitamin C-rich foods include citrus fruits, kiwifruit, broccoli and capsicums.

VITAMIN A

Vitamin A is needed to form rhodopsin, a molecule used by specialised cells called rods in the retina that detect light in dim or dark conditions. Beta-carotene a plant compound is a precursor to vitamin A and it also protects the eyes through its antioxidant capacity. Vitamin A is found in liver, egg yolks, fish and cod liver oil, while beta-carotene is found in yellow and orange vegetables, such as carrots, kumara and pumpkin. Beta-carotene is also found in green leafy vegetables (the yellow/orange pigment is masked by the green from chlorophyll, another plant compound).

LUTEIN AND ZEAXANTHIN

These plant compounds belong to the carotenoid family (of which beta-carotene is also a member), and are concentrated in the macula of the eye. Lutein and zeaxanthin are powerful antioxidants that protect against oxidative damage, and they filter and protect the eyes from blue light. This is particularly important as this is the type of light emitted from screens (think smartphones, tablets, laptops, computers and TVs), which our eyes are increasingly exposed to. The best food sources of lutein and zeaxanthin are green leafy vegetables (such as spinach, kale, silverbeet, broccoli, parsley), egg yolks, kiwifruit, corn and pumpkin.

ZINC

Zinc deficiency is associated with functional impairments in various parts of the eye. Zinc is needed for the conversion of retinol (a form of vitamin A) into retinal, which is required for night vision. Zinc is also needed to deliver vitamin A to the eyes, and it works with vitamin C to protect the eyes against oxidative damage. Zinc is found in oysters from clean waters, meat, eggs, sunflower seeds and pumpkin seeds.

Early and frequent screenings the key to child vision health – The Tennessean

June 5th, 2017 8:44 pm

Eye health experts recommend early and frequent vision screenings for children, who may not understand or be able to communicate if they are not seeing well.(Photo: Andrey Kuzmin - Fotolia)

According to the American Optometric Association, as much as 80 percent of a childs learning is visual. So whether theyre reading a book, learning math problems on a dry erase boardor dissecting a frog in biology class, kids rely on their vision as much as, if not more than, any other educational tool.

Melody Thompsons daughter Tyra was preparing to start kindergarten when the Nashville-based mom of three noticed that one of Tyras eyelids was drooping. After seeing a doctor, they learned that the official name for the condition is ptosis. And while Tyras ptosis didnt affect her sight, in severe cases, it can cause a complete obstruction of vision in an eye if the eyelid droops low enough to cover the pupil.

More: 13 startups get funding to troubleshoot a few of health care's many problems

Dr. Carl Flinn, an optometrist in Memphis, notes that ptosis is fairly common in children. Another condition frequently seen in children is amblyopia, or the lack of visual development.

One of the most common causes (of amblyopia)is a major refractive error, Flinn says. If you notice your child consistently holding things very closely in order to see, and they are squinting to see the television, then suspect a visual problem and a possible need for glasses.

The major refractive errors that can cause amblyopia include near-sightedness (also known as myopis), in which distant objects are out of focus; far-sightedness, in which distant objects are clear and close objects appear blurred; and astigmatism, in which eyes take on a football shape and both distant and close objects appear blurred.

Less frequent, Flinn says, are cases of infantile cataracts, which can cause irreversible vision loss if left untreated, or instances in which a child can see clearly out of one eye but poorly out of the other.

Your child often does not recognize the discrepancy and accepts this condition as normal and may not bring it to your attention.

Regardless of the condition, however, Flinn and other eye health experts recommend early and frequent vision screens for children.

And, says Dr. Ming Wang, director of Nashvilles Wang Vision 3D Cataract & LASIK Center, failure to closely monitor a childs visual health early can lead to long-term damage.

The visual cortex, the part of our brain involved in visual interpretation, develops primarily in early childhood, from birth until about age 10, he explains. Proper development of the visual cortex is critically dependent on continued and proper visual signal stimulation. So if a child cannot see well at, say, age 3, and the problem is not corrected immediately, the child may develop irreversible, permanent loss of sight.

Wang advises parents to begin screening their children at birth. At that age, his staff looks for congenital problems that may affect a babys vision, while older infants are tested on their ability to fixate on and follow anobject. Toddlers are asked to recognize patterns, and older children are tested with a standard vision chart.

Wang also encourages parents to be vigilant about screenings even if their child doesnt appear to have any vision problems.

Unlike adults, who are more communicative and can relate their vision problems, children tend to be less communicative, he says. For example, a childs school grades may fall, simply because he cant see the board at the front of the room, but he may not tell his parent. So the parent might suspect another problem.

At Tyras initial vision screening, when doctors diagnosed her ptosis, they also noticed that she was nearsighted. And even though Tyras need was only slight at the time, Thompson immediately ordered glasses for her daughter. Tyras nearsightedness has continued to progress over the years (shes now 12 and in the fifth grade), but Thompsons diligence has ensured that those vision problems havent negatively impacted any other aspect of her life.

Tyra has annual eye visits, and we just got the clear from Vanderbilt to see a regular eye doctor instead of having to see the specialist, Thompson says. Im just thankful for a good team of doctors who showed real concern from the beginning to make sure she received the best care possible.

Thompson notes that her own nearsightedness (she began wearing glasses in seventh grade) may have caused her to pay extra attention to the visual development of her children.

I will never forget putting my glasses on and walking outside for the first time, Thompson says. I had no idea you could see the leaves on trees from far away! That has been a crazy, ingrained memory for me, and I never wanted my children to have that experience.

Unfortunately, though, not all parents are as acutely aware of the importance of monitoring their childs eye health. In considering the biggest challenges in diagnosing and treating child vision problems, Wang says it actually comes down to a lack of parental education.

Because children are not independent, and they depend largely on their parents for all aspects of their lives, it is of paramount importance that adults be properly educated about vision care for their children, says Wang. We host monthly vision education seminars at the Wang Vision Center to provide that important education for adults.

Dr. Rebecca Norris, an optometrist at Nashvilles AccessorEyes, agrees.

Many children grow up in homes where the parents have great eyesight and do not need vision correction. Many of these parents do not even realize that the child is having problems because it is not on their radar or on their normal list of annual doctor appointments.

For parents who rely on the yearly vision screening performed by a primary care physician, Norris says that may not provide a comprehensive overview of a childs visual health.

Many pediatricians and schools screen a childs vision by simply having him read the eye chart; yet there are so many children who can pass these screenings but still need glasses, she says. Its so important to have an optometrist do a full comprehensive vision and eye health exam. And these full exams should be performed each school year because vision can change so drastically from year to year.

Falling grades

Excessive squinting

Head tilting

Sitting closer and closer to the TV

Skipping lines when reading

Getting tired when reading

Avoiding reading altogether

Eyes that turn in or out

We are cognizant to apply sunscreen but forget that the suns UV rays can also cause damage to the eyes, which can increase the risk of cataract, corneal damage, and macular degeneration," says optometrist Carl Flinn.

Sunglasses marked UV 400 or 100% UV blockage with a wraparound style along with a wide brim hat are a must for a day outside.

Mike Zimmer given permission to rejoin Vikings after eye surgery recovery – ESPN

June 5th, 2017 8:44 pm

MINNEAPOLIS -- After a two-week break from coaching following his latest eye surgery, Minnesota Vikings coach Mike Zimmer was told he could return to work on his 61st birthday.

Zimmer, who spent the past two weeks at his Kentucky ranch after his eighth surgery to repair a detached retina in his right eye, was cleared to return to coaching after a follow-up appointment Monday morning. He will be back on the field as the Vikings resume organized team activities Tuesday.

The coach, who had his first eye surgery Nov. 1 after having vision issues during the team's Oct. 31 loss to the Chicago Bears, eventually had to miss the Vikings' Dec. 1 game against the Dallas Cowboys because of an emergency operation.

His latest operation, on May 17, prompted the Vikings to send Zimmer on a leave of absence so he could recover away from the stresses of coaching. He was still able to watch film of practice from his ranch and conducted conference calls with his coaches each afternoon.

Vikings rookie Ifeadi Odenigbo got a late start in football with hesitant parents, including a mother who is a pediatrician. But he found a path.

The Raiders and Lions could soon lock up their star quarterbacks with mega-money extensions. The Bills, Chargers and Vikings have big decisions to make. Here are the top looming roster questions facing every team.

Zimmer had a gas bubble put in his right eye to hold his retina in place. He said May 26 that if his retina stayed put once the gas bubble dissolved, "we should be good to go." But even if his eyesight worsened, the coach said, he had no plans to step away from his job permanently.

"Like I texted Kyle Rudolph, I said, 'Hey, I'll be back shortly with one eye or two. Doesn't really matter -- I'm going to be back,'" Zimmer said. "So we can put that me retiring thing or whatever to bed quickly."

Zimmer said in March that doctors have told him he has a "high likelihood" of similar problems eventually developing in his left eye.

The Vikings' offseason program concludes with three OTAs this week and the team's mandatory minicamp June 13-15.

Cherokee Nation program benefits pre-diabetes patients – Muskogee Daily Phoenix

June 5th, 2017 8:44 pm

A program sponsored by the Cherokee Nation has been successful in reducing the risk of diabetes in pre-diabetics.

"People with pre-diabetes who lose 7 percent of their body weight through a healthy lifestyle intervention reduce their risk for diabetes by 58 percent," said Tonya Wapskineh, Cherokee Nation diabetes prevention manager.

But those who took metformin, a diabetes medication, reduced their risk by 30 percent.The bottom line is that the healthy lifestyle group reduced their risk for diabetes twice as much as those who were placed on medication, Wapskineh said.

With that success, Wapskineh is looking for more Cherokees who qualify for the program. Some of the qualifications include having a history of gestational diabetes for women, a body mass index of over 24 or a history of diabetes in the family.

While joining the class is voluntary, some are referred by their medical provider. The program's goal is to get everyone to lose 7 percent of their body fat.

"It's kind of a wake-up call for them especially when their doctor tells them they can do something to prevent diabetes," said Karen Bryant, physical activity specialist.

A lot of participants have lost up to four pounds in a couple of weeks just by cutting back and not eating french fries every day.

Classes last a year with the first two months as weekly class, the next four months are bi-weekly classes and the remaining meetings are once a month,Wapskineh said.

Most Cherokees have a diet high in fat and fried foods with little vegetables and fruit, Bryant said. She says their eating habits were learned from childhood.

Participants are not told to stop eating that kind of food.

"Wegive them ways to enjoy these foods by cutting portion sizes, cutting fat out of food and replacing unhealthy cooking oil with healthier ones," Bryant said.

Using this program, one Cherokee man started out at 307 pounds, and a year later he is maintaining 175 pounds, Bryant said.

"When he first started his activity program he could barely get one-quarter around the track, and now he walks every chance he gets and still uses a food journal and that's been about five years ago," she said.

His main success was using a food journal and keeping track of what he ate.

Volunteers have a physical activity goal of 150 minutes per week.

"If they can sing or talk normally and are being active they need to work a little harder. If they can't talk they need to slow it down,"Wapskineh said.

For those who are pretty sedentary, Bryant recommends 15 minutes of walking twice a day and work up to 150 minutes a week. For faster weightloss, 60 minutes of brisk walking a day is recommended.

"From what I've seen through the program is that the more education they receive on how to correct their lifestyle, the more effective it is than going to the doctor and getting a pill,"Wapskineh said.

At the Cherokee Nation Wapskineh said she has actually seen their providers move into preventive medicine and are more supportive of promoting the healthy lifestyle program.

Wapskineh's budget is $400,000 and she would like to see that doubled to possibly establish diabetic prevention centers in all 14 counties within the Cherokee Nation jurisdiction.

"But our work is federally funded and the money is just not there that's just my dream," she said.

Usher Missed the Manchester Benefit Concert to Take His Son to Summer Camp – PEOPLE.com

June 5th, 2017 8:44 pm

Usherhas revealed why he was absent from Ariana Grandes One Love Manchester benefit concert on Sunday: it was his sons first day at summer camp for children with diabetes.

The 38-year-old singer shared a post on Instagram Monday explaining why he did not perform in Manchester despite being announced as part of the star-studded lineup.

So happy to see that last nights concert in Manchester proved that love always prevails, he captioned a photo of the stage. I would have loved to be there but it was my sons first day at Camp Kudzu, one of the few summer camps for kids living with diabetes. This was an important day for him and for myself as a proud father.

He concluded his message, Stay strong UK.

The Voicealum has previously spoken out about his 9-year-old son Usher V(aka Cinco)s struggle withtype 1 diabetes and used his platform to advocate fora cure for the disease, which prevents the body from producing insulin.

Achild that every day has to prick himself and has to be cautious of what he eats and also to carry this disorder around that really is the type of bravery that we all aspire to have, Usher told PEOPLE at the 2015JDRFs Promise Ball, which aimed to raise awareness and moneyfor research and a cure.

While hes inspired by his son (with ex Tameka Foster), the I Dont Mind singer says its been hard on him too.

Theres been some difficult moments, he said, but having dealt with it on a daily basis, I have a great deal of understanding of what people have to deal with. Its personal.

Type 2 diabetes: New biopolymer injection may offer weeks of glucose control – Medical News Today

June 5th, 2017 8:44 pm

Keeping blood glucose levels as close to normal as possible is important for people with type 2 diabetes, as it lowers the risk of serious complications. However, despite a long list of treatment options, patients still struggle with glucose control, especially when working out meal-specific doses. Treatments that cut down on injections are seen as a way to overcome this problem. Now, in a paper in Nature Biomedical Engineering, scientists describe a new biopolymer injection that could potentially replace daily or weekly insulin shots with one that need only be given once or twice per month.

Untreated diabetes results in high levels of blood sugar, or glucose, which in the long-term can lead to blindness, kidney disease, heart disease, stroke, and amputation of lower limbs.

Diabetes arises because of a problem with insulin, which is a hormone that is made in the pancreas and which helps cells to absorb glucose so that they can use it for energy.

In type 1 diabetes, the body does not make enough insulin, while in type 2 diabetes - which accounts for 90 to 95 percent of diabetes cases - it cannot use it properly.

Although the incidence of newly diagnosed diabetes is starting to drop in the United States, it is still a huge public health problem that affects more than 29 million people.

In 2013, the Centers for Disease Control and Prevention (CDC) suggested that diabetes was the seventh leading cause of death in the U.S., and that more than a fifth of the country's healthcare costs are for people diagnosed with diabetes.

In their study paper, biomedical engineers from Duke University in Durham, NC, explain that "despite the long list of treatment options," nearly half of type 2 diabetes cases in the U.S. "are not properly managed."

The researchers suggest that one reason for such a high rate of failure in the management of type 2 diabetes is that patients struggle to keep to treatment regimens, especially when they are required to frequently deal with complicated meal-specific doses.

Another reason they give is that many of the widely used treatments bring unwanted side effects, such as raising the risk of low blood sugar, known as hypoglycemia, or weight gain.

From a drug development point of view, one of the biggest challenges in treating diabetes is that insulin demands in the body are always changing.

In order to address this challenge, there are now treatments for type 2 diabetes that use a new class of drugs called glucagon-like peptide-1 (GLP1) receptor agonists. These drugs use GLP1, a signaling molecule, to trigger insulin release in the pancreas.

Because GLP1 does not last long in the body, drug developers have used various ways to extend its half-life - such as fusing it with various synthetic and biological compounds. These attempts have succeeded in extending the drug's active life in the human body for up to a week.

However, the researchers note that despite this improvement, so far none of the current treatments have solved the problem of the drug's effectiveness gradually decreasing over time.

The new approach that the Duke researchers describe fuses GLP1 with a heat-sensitive biopolymer called elastin-like polypeptide. Held in a solution, the biopolymer drug can be injected into the skin with a normal needle.

Once it is in the bloodstream, the heat of the body causes the biopolymer to form a biodegradable gel that releases the drug slowly and steadily, without the "peaks and troughs" associated with other forms of GLP1 delivery.

Using results from previous work on GLP1 for glucose control, the team tried different molecular designs of the new delivery solution.

They eventually found a design of the biopolymer that could control glucose levels in mice for up to 10 days with a single injection. This was a great improvement on previous attempts, after which the controlled release had only lasted for 2 or 3 days.

In tests on rhesus monkeys, the team found that the optimized formulation resulted in glucose control lasting for more than 14 days from a single injection. Also, the drug was released at a constant rate, without "peaks and troughs," during the whole period.

Senior author Ashutosh Chilkoti, a professor of biomedical engineering at Duke, says that they "managed to triple the duration of this short-acting drug for type 2 diabetes, outperforming other competing designs."

At present, patients using dulaglutide - the longest-lasting controlled release treatment for type 2 diabetes - have to inject themselves once per week. Patients on standard insulin treatments must inject themselves at least twice each day.

The team now plans to test the biopolymer on other animals and investigate how the immune system reacts to repeated injections. They also want to find out how well it performs for the controlled release of drugs in other areas, such as pain management.

"What's exciting about this work was our ability to demonstrate that the drug could last over 2 weeks in non-human primates. Because our metabolism is slower than monkeys and mice, the treatment should theoretically last even longer in humans, so our hope is that this will be the first bi-weekly or once-a-month formulation for people with type 2 diabetes."

Talking Biotech: Can biotechnology help protect forests from pests … – Genetic Literacy Project

June 5th, 2017 8:41 pm

Forests are under many threats, from new pests and pathogens, to invasive trees, to climate. The advancement of these traits by far exceeds the natural response of trees to acclimate, and outpaces the efforts to traditionally breed trees for forest conservation and restoration. Dr. Ellen V. Crocker is a postdoctoral researcher at the University of Kentucky. She talks about the current threats to forests including sudden oak death, chestnut blight and the emerald ash borer. She also discusses efforts in integrating new biotech tools in forest improvement, including genetic engineering, speed breeding, and gene drive approaches. Hosted by Dr. Paul Vincelli (@Pvincell).

June 5th, 2017 8:41 pm

Hunger and scarcity of food is one of the major problems in most of the developing countries. Moreover with the increased food price in the developing countries, more than 100 million people are suffering from scarcity of food and hunger. So these are the major recurring challenges that have tackled for centuries. To overcome from these issues, new technologies have enabled the significant changes for improving the quality of life.

Todays modern molecular biotechnology has enabled new solution to overcome from these challenges. The evolution of molecular biotechnology industry has substantially increased its efforts to find alternative to synthetic food and new innovations on the conventional plant breeding technologies. Also the advanced biotechnology offers an exciting and environmentally new way to reach the customer demand for sustainable agriculture growth.

Here we shall have a brief discussion on modern biotechnology and how it solves world hunger.

1. Prevent Hunger And Malnutrition

The term malnutrition is the medical terminology for the people who are all suffering from the hunger. As per the recent survey from the Agricultural Organization, more than 900 million people suffering from malnutrition in worldwide. Children are the major victims for the malnutrition. To overcome from this researchers have created Golden Rice which contains three new genes. This rice is available for mass distribution at low cost. This is just one sample, there are hundreds of new biotech products which prevent hunger and malnutrition.

2. Longer Lasting Produce

Most of the food products will spoil soon, especially in areas with limited transportation and refrigeration capability. But the biotech products could reduce looses to spoilage. In most of the developing countries, farmers can get benefits from crops with delayed ripening fruits or vegetables. This also allows greater flexibility in distribution of products in remote places.

3. Nutritionally Rich Food

Molecular biotechnology researchers have developed nutritionally rich food with beta-carotene and precursor to Vitamin A food for the low poverty level people at low cost. The United Nations Food and Agricultural Department have stated: The potential to grow rice with an enhanced micronutrient can contribute to reducing malnutrition.

4. Tackling New Diseases

Before some of the genetic engineers was only dealing with pharmaceutical industry. But now biotechnology field has spread its wings wider in the health care industry and contribute to treat medical diseases by avoiding the use of insulin and other chemicals. With biotechnology, it includes interferon therapy to dissolve ones immune system and introduced hepatitis B vaccine for low cost.

Arthritis symptoms – gentle jogging could benefit knee and hip joints … – Express.co.uk

June 5th, 2017 8:41 pm

GETTY

A gentle jog could benefit the knees and hips and reduce the risk of the osteoarthritis, which affects millions of people in the UK.

There is currently no cure for the condition but sufferers can treat the condition with drugs - commonly non-steroidal anti-inflammatory drugs and by changing certain lifestyle factors.

Previously, experts have suggested jogging could damage the major joints and recommend other exercises such as pilates.

A new study looked at more than 110,000 people across the world. It found 3.5 per cent of people who run for fun and to stay fit developed arthritis in the knees or hips.

GETTY

This, experts said was compared to 10.2 per cent of those who didn't do any running - and was true for both men and women.

However the researchers said people should be wary of doing too much - as training and running competitively increased the risk to 13.3 per cent.

Dr Eduard Alentorn-Geli, of the Mayo Clinic in Rochester, Minnesota, and orthopaedic surgeon said: "The principal finding in this study is that, in general, running is not associated with osteoarthritis.

"The novel finding in our investigation is the increased association between running and arthritis in competitive - but not in recreational - runners.

When a joint develops osteoarthritis, some of the cartilage covering the ends of the bones gradually roughens and becomes thin, and the bone underneath thickens.

Running is not associated with osteoarthritis

According to Arthritis Research UK, over eight million people in the UK suffer from osteoarthritis - a condition perceived as only a disorder that affects the elderly.

Dr Alentorn-Gel and researchers from Spain, Sweden, and Canada pooled data from 17 studies involving a total of 114,829 people to evaluate the association of osteoarthritis with running.

The researchers compared the prevalence of the disease between runners and sedentary individuals who did not run.

Runners were considered 'competitive' if they were identified themselves as professional or elite athletes or participated in international competitions.

The researchers calculated the rate and odds ratio for osteoarthritis between runners at both competitive and recreational levels and people who did no exercise individuals.

They also looked at the location of arthritis in the hip or knee, gender and the years of exposure to running - less or more than 15 years.

GETTY

Dr Alentorn-Geli and his colleagues were not able to determine the amount of running that is safe for these joints.

The study was published in the Journal of Orthopaedic & Sports Physical Therapy.

Olivia Belle from Arthritis Research UK has previously told Express.co.uk said: If you have joint pain or mild osteoarthritis you might not always feel much like exercising.

But keeping active is one of the best ways to manage the symptoms.

Regular, safe, simple and effective exercise has been proven to greatly reduce pain and stiffness in joints.

Its also important for your joints that you maintain a healthy weight for you, and exercising regularly will help you with that.

Arthritis cure: Ditching THIS from your diet could ease symptoms – Express.co.uk

June 5th, 2017 8:41 pm

Reducing carbohydrates, such as bread and pasta, could better kickstart your immune system to fight disease.

One of its components - glucose - interferes with some of the bodys immune cells.

The simple sugar is generated when we digest carbs, and as well as being vital for energy its also important in cell division and growth.

However, in some cases it can stop the immune system working properly, and therefore help drive disease.

GETTY

Research by Trinity College Dublin discovered that when certain cells are starved of glucose, they stimulated the immune system.

Research by Trinity College Dublin discovered that when certain cells are starved of glucose, they stimulated the immune system.

These dendritic cells are the part of the immune system that monitors our body for signs of danger.

When they arent given of glucose, they push the immune systems T lymphocytes into action.

Indeed, they are what directly fight cancer and inflammatory diseases, such as arthritis and heart problems.

There are other immune cells, however, which become dysfunctional if they're starved of glucose.

This is because when responding to infection they have a high demand for it.

The research outlines how various cells may interact with glucose differently.

GETTY

The study authors believe the new findings could open up new approaches to treating cancers and immune-related conditions.

David Finlay, lead researcher, said: It is becoming clear that glucose is an important signaller in our immune system, in that cells that have access to glucose behave very differently to those that do not.

We have discovered that dendritic cells are actually better at stimulating immune responses when starved of glucose, which is not the case for any of the other immune cells that have been analysed.

The discovery that T cells and dendritic cells compete with each other for glucose offers a new and exciting insight into how glucose can regulate dendritic cell function.

Walkers stepping up to stamp out arthritis – Tbnewswatch.com

June 5th, 2017 8:41 pm

THUNDER BAY - Even though damp, cold weather can make even standing up difficult for people living with severe arthritis, dozens of people braved a grey morning to walk in support of the Arthritis Society.

On Sunday, more than 70 people participated in the 8th Annual Walk to Fight Arthritis at Prince Arthurs Landing.

Mariann Sawicki, committee member with the Arthritis Society of Thunder Bay, said she is happy with the turn out.

The weather probably deterred some people, she said. There are a lot of people out here. It just goes to show the importance. Everybody wants to do what they can for different diseases. They are very eager to help out and show their support.

This year, the fundraising target was $19,000 and prior to the walk starting the Arthritis Society had already raised $12,000. The money raised will be used to fund research for arthritis treatments and finding a cure.

Arthritis refers to a number of different disorders that target the joints in the body. It can cause stiffness, swelling, and reduced motion of joints. Types of arthritis include osteoarthritis, rheumatoid arthritis, lupus, gout, and Lyme Disease.

Sawicki said sometimes there are misconceptions that arthritis is a disease that only affects people as they age, but she said it can affect anyone.

I think there may be some misconception, she said. A lot of people may think it is for older people, but thats not the case. Im a registered nurse and Ive seen all kind of different types of arthritis. People need to realize that.

And despite the weather on Sunday, people were out not only in support of stamping out arthritis, but also practicing one of the best treatments for the disease.

Movement with arthritis is one of the best things for you and your joints, Sawicki said. Being active really helps. This weather is kind of damp, so it does trigger some symptoms for people, but people are still out here and ready to go.

Gene therapy could wipe immune memory and "turn off" severe allergies – New Atlas

June 5th, 2017 6:44 am

The team hopes to develop a single, injected, gene therapy treatment that could eliminate many severe allergic responses (Credit: University of Queensland)

Scientists may be one step closer to discovering a way to genetically "turn off" allergic responses with a single injection. A team of researchers at the University of Queensland has developed a new process that has successfully silenced a severe allergic response in mice, using blood stem cells engineered with a gene that can target specific immune cells.

The big challenge previous allergy researchers faced was that immune cells, known as T-cells, tended to develop a form of "memory" so that once someone developed an immune response to an allergen, it would easily recur upon future contact. The key was finding a way to erase that "memory" response to the protein in the allergen causing the immune reaction.

NEW ATLAS NEEDS YOUR SUPPORT

It's just US$19 a year.

"We take blood stem cells, insert a gene which regulates the allergen protein and we put that into the recipient," says Professor Ray Steptoe, explaining the new process developed by his team at The University of Queensland. "Those engineered cells produce new blood cells that express the protein and target specific immune cells, 'turning off' the allergic response."

The team's initial clinical investigations looked at an experimental asthma allergen, with the new process found to successfully terminate established allergic responses in sensitized laboratory mice. While the initial research has focused on a very specific asthma allergen, Professor Steptoe believes the process could be applied to many other severe allergic responses, such as peanuts, bee venom and shell fish.

The long-term goal of the research would be to develop a therapy that could cure specific allergies with a single injection, much like a vaccine.

"We haven't quite got it to the point where it's as simple as getting a flu jab," says Professor Steptoe, "so we are working on making it simpler and safer so it could be used across a wide cross-section of affected individuals."

The team is realistic about the time it will take before this discovery results in practical benefits for allergy sufferers, with at least five years more laboratory work needed before even human trials can be conducted. But this new discovery could mean that, within 10 or 15 years, asthma and other lethal allergic responses might be eliminated with a single, one-time treatment.

The findings were recent published in the journal JCI Insight.

What Are Stem Cells – Checkbiotech.org (press release)

June 5th, 2017 6:43 am

Tissue-specific stem cells

Tissue-specific stem cells, which are sometimes referred to as adult or somatic stem cells, are already somewhat specialized and can produce some or all of the mature cell types found within the particular tissue or organ in which they reside. Because of their ability to generate multiple, organ-specific, cell types, they are described as multipotent. For example, stem cells found

Stem cells are the foundation cells for every organ and tissue in our bodies. The highly specialized cells that make up these tissues originally came from an initial pool of stem cells formed shortly after fertilization. Throughout our lives, we continue to rely on stem cells to replace injured tissues and cells that are lost every day, such as those in our skin, hair, blood and the lining of our gut. Stem cells have two key properties: 1) the ability to self-renew, dividing in a way that makes copies of themselves, and 2) the ability to differentiate, giving rise to the mature types of cells that make up our organs and tissues.

Tissue-specific stem cells Tissue-specific stem cells, which are sometimes referred to as adult or somatic stem cells, are already somewhat specialized and can produce some or all of the mature cell types found within the particular tissue or organ in which they reside. Because of their ability to generate multiple, organ-specific, cell types, they are described as multipotent. For example, stem cells found within the adult brain are capable of making neurons and two types of glial cells, astrocytes and oligodendrocytes. Tissue-specific stem cells have been found in several organs that need to continuously replenish themselves, such as the blood, skin and gut and have even been found in other, less regenerative, organs such as the brain. These types of stem cells represent a very small population and are often buried deep within a given tissue, making them difficult to identify, isolate and grow in a laboratory setting. Neuron Dr. Gerry Shaw, EnCor Biotechnology Inc. Astrocyte Abcam Inc. Oligodendrocyte Dhaunchak and Nave (2007). Proc Natl Acad Sci USA 104:17813-8 http://www.isscr.org Embryonic stem cells Embryonic stem cells have been derived from a variety of species, including humans, and are described as pluripotent, meaning that they can generate all the different types of cells in the body. Embryonic stem cells can be obtained from the blastocyst, a very early stage of development that consists of a mostly hollow ball of approximately 150-200 cells and is barely visible to the naked eye. At this stage, there are no organs, not even blood, just an inner cell mass from which embryonic stem cells can be obtained. Human embryonic stem cells are derived primarily from blastocysts that were created by in vitro fertilization (IVF) for assisted reproduction but were no longer needed. The fertilized egg and the cells that immediately arise in the first few divisions are totipotent. This means that, under the right conditions, they can generate a viable embryo (including support tissues such as the placenta). Within a matter of days, however, these cells transition to become pluripotent. None of the currently studied embryonic stem cell lines are alone capable of generating a viable embryo (i.e., they are pluripotent, not totipotent). Why are embryonic stem cells so valuable? Unlike tissue-specific (adult) stem cells, embryonic stem cells have the potential to generate every cell type found in the body. Just as importantly, these cells can, under the right conditions, be grown and expanded indefinitely in this unspecialized or undifferentiated state. These cells help researchers learn about early human developmental processes that are otherwise inaccessible, study diseases and establish strategies that could ultimately lead to therapies designed to replace or restore damaged tissues. Induced pluripotent stem cells One of the hottest topics in stem cell research today is the study of induced pluripotent stem cells (iPS cells). These are adult cells (e.g., skin cells) that are engineered, or reprogrammed, to become pluripotent, i.e., behave like an embryonic stem cell. While these iPS cells share many of the same characteristics of embryonic stem cells, including the ability to give rise to all the cell types in the body, it is important to understand that they are not identical. The original iPS cells were produced by using viruses to insert extra copies of three to four genes known to be important in embryonic stem cells into the specialized cell. It is not yet completely understood how these three to four reprogramming genes are able to induce pluripotency; this question is the focus of ongoing research. In addition, recent studies have focused on alternative ways of reprogramming cells using methods that are safer for use in clinical settings. Disease- or patient-specific pluripotent stem cells One of the major advantages of iPS cells, and one of the reasons that researchers are very interested in studying them, is that they are a very good way to make pluripotent stem cell lines that are specific to a disease or even to an individual patient. Disease-specific stem cells are powerful tools for studying the cause of a particular disease and then for testing drugs or discovering other approaches to treat or cure that disease. The development of patientspecific stem cells is also very attractive for cell therapy, as these cell lines are from the patient themselves and may minimize some of the serious complications of rejection and immunosuppression that can occur following transplants from unrelated donors. Moving stem cells into the clinic Clinical translation is the process used to turn scientific knowledge into real world medical treatments. Researchers take what they have learned about how a tissue usually works and what goes wrong in a particular disease or injury and use this information to develop new ways to diagnose, stop or fix what goes wrong. Before being marketed or adopted as standard of care, most treatments are tested through clinical trials. Sometimes, in attempting new surgical techniques or where the disease or condition is rare and does not have a large enough group of people to form a clinical trial, certain treatments might be tried on one or two people, a form of testing sometimes referred to as innovative medicine. For more information on how science becomes medicine, please visit http://www.closerlookatstemcells.org. Current therapies Blood stem cells are currently the most frequently used stem cells for therapy. For more than 50 years, doctors have been using bone marrow transplants to transfer blood stem cells to patients, and more advanced techniques for collecting blood stem cells are now being used to treat leukemia, lymphoma and several inherited blood disorders. Umbilical cord blood, like bone marrow, is often collected as a source of blood stem cells and in certain cases is being used as an alternative to bone marrow transplantation. Additionally, some bone, skin and corneal diseases or injuries can be treated by grafting tissues that are derived from or maintained by stem cells. These therapies have also been shown to be safe and effective. Potential therapies Other stem cell treatments, while promising, are still at very early experimental stages. For example, the mesenchymal stem cell, found throughout the body including in the bone marrow, can be directed to become bone, cartilage, fat and possibly even muscle. In certain experimental models, these cells also have some ability to modify immune functions. These abilities have created considerable interest in developing ways of using mesenchymal stem cells to treat a range of musculoskeletal abnormalities, cardiac disease and some immune abnormalities such as graft-versus-host disease following bone marrow transplant. Remaining challenges Despite the successes we have seen so far, there are several major challenges that must be addressed before stem cells can be used as cell therapies to treat a wider range of diseases. First, we need to identify an abundant source of stem cells. Identifying, isolating and growing the right kind of stem cell, particularly in the case of rare adult stem cells, are painstaking and difficult processes. Pluripotent stem cells, such as embryonic stem cells, can be grown indefinitely in the lab and have the advantage of having the potential to become any cell in the body, but these processes are again very complex and must be tightly controlled. iPS cells, while promising, are also limited by these concerns. In both cases, considerable work remains to be done to ensure that these cells can be isolated and used safely and routinely. Second, as with organ transplants, it is very important to have a close match between the donor tissue and the recipient; the more closely the tissue matches the recipient, the lower the risk of rejection. Being able to avoid the lifelong use of immunosuppressants would also be preferable. The discovery of iPS cells has opened the door to developing patient-specific pluripotent stem cell lines that can later be developed into a needed cell type without the problems of rejection and immunosuppression that occur from transplants from unrelated donors. Third, a system for delivering the cells to the right part of the body must be developed. Once in the right location, the new cells must then be encouraged to integrate and function together with the bodys other cells. http://www.isscr.org Glossary Blastocyst A very early embryo that has the shape of a ball and consists of approximately 150-200 cells. It contains the inner cell mass, from which embryonic stem cells are derived, and an outer layer of cells called the trophoblast that forms the placenta. Cell line Cells that can be maintained and grown in a dish outside of the body. Clinical translation The process of using scientific knowledge to design, develop and apply new ways to diagnose, stop or fix what goes wrong in a particular disease or injury. Differentiation The process of development with an increase in the level of organization or complexity of a cell or tissue, accompanied by a more specialized function. Embryo The early developing organism; this term denotes the period of development between the fertilized egg and the fetal stage. Embryonic stem cell Cells derived from very early in development, usually the inner cell mass of a developing blastocyst. These cells are self-renewing (can replicate themselves) and pluripotent (can form all cell types found in the body). Induced pluripotent stem (iPS) cell Induced pluripotent cells (iPS cells) are stem cells that were engineered (induced) from non-pluripotent cells to become pluripotent. In other words, a cell with a specialized function (for example, a skin cell) that has been reprogrammed to an unspecialized state similar to that of an embryonic stem cell. Innovative medicine Treatments that are performed on a small number of people and are designed to test a novel technique or treat a rare disease. These are done outside of a typical clinical trial framework. In vitro fertilization A procedure in which an egg cell and sperm cells are brought together in a dish to fertilize the egg. The fertilized egg will start dividing and, after several divisions, forms the embryo that can be implanted into the womb of a woman and give rise to pregnancy. Mesenchymal stem cells Mesenchymal stem cells were originally discovered in the bone marrow, but have since been found throughout the body and can give rise to a large number of connective tissue types such as bone, cartilage and fat. Multipotent stem cells Stem cells that can give rise to several different types of specialized cells, but in contrast to a pluripotent stem cell, are restricted to a certain organ or tissue types. For example, blood stem cells are multipotent cells that can produce all the different cell types that make up the blood but not the cells of other organs such as the liver or brain. Pluripotent stem cells Stem cells that can become all the cell types that are found in an implanted embryo, fetus or developed organism. Embryonic stem cells are pluripotent stem cells. Self-renewal The process by which a cell divides to generate another cell that has the same potential. Stem cells Cells that have both the capacity to self-renew (make more stem cells by cell division) and to differentiate into mature, specialized cells. Tissue-specific stem cells (also known as adult or somatic stem cells) Stem cells found in different tissues of the body that can give rise to some or all of the mature cell types found within the particular tissue or organ from which they came, i.e., blood stem cells can give rise to all the cells that make up the blood, but not the cells of organs such as the liver or brain. Totipotent stem cells Stem cells that, under the right conditions, are wholly capable of generating a viable embryo (including the placenta) and, for humans, exist until about four days after fertilization, prior to the blastocyst stage from which embryonic stem cells are derived.

Do Carrots Really Help Your Vision? : The Salt : NPR – NPR

June 5th, 2017 6:43 am

Many lifelong carrot eaters feel a little betrayed.

"There is no way [carrots] affect eyesight," says Silvio Fontecchio, a project manager at a print shop in Tallahassee, Fla., whose parents told him when he was young that munching the orange veggie would help his eyes. "As a kid, my go-to snack was carrots and ranch [dressing], and I have really bad nearsighted vision."

For some, disillusion comes even earlier: When Rozalynn Goodwin, a health care executive in Columbia, S.C., told her 6-year-old son to eat his carrots to help his eyesight, he said, "I've been eating carrots, and I still had to get glasses." Goodwin didn't have a response.

We've all been sold the bill of goods that carrots improve eyesight. Yet many faithful crunchers still find themselves squinting at street signs. So, do carrots actually help us see better?

Absolutely, according to ophthalmologist Rebecca Taylor, a clinical spokesperson for the American Academy of Ophthalmology and one of the most enthusiastic carrot champions around.

"There's a reason why these adages become adages: in large part because they're true," says Taylor. "When you eat a carrot, you're helping your body take a light source [and interpret it]. ... That makes food pretty darn important. That's the stuff that will keep me up at night, it's so exciting."

For eyesight, a carrot's nutritional punch comes from beta carotene, a "carotenoid" the body can convert into vitamin A, according to T. Michael Redmond, chief of the Laboratory of Retinal Cell and Molecular Biology at the National Eye Institute. Vitamin A enables opsin proteins to form in "cone cells" and rhodopsin protein to form in "rod cells" near the back of the eye. Cone cells process light in daytime conditions, while rhodopsin does the same in dim light. When light hits rhodopsin or cone opsins, it creates an electric impulse that travels to the brain for interpretation, helping us see.

Vitamin A deficiency can lead to night blindness, a condition in which people have difficulty adjusting their vision to low levels of light. "You go into a movie theater," Taylor explains, "and you see nothing. You can't process the little bit of light that's in there."

But night blindness is rare in the U.S. because vitamin A deficiency is rare in this country, according to the Centers for Disease Control and Prevention. That may help explain why carrot enthusiasts don't have superior eagle eyes compared with carrot detractors: Even without carrots, most people are getting enough vitamin A from other sources. (Sweet potatoes can provide even more vitamin A than carrots do, and dark leafy greens like spinach and kale are also vitamin A treasure troves.)

Enabling vision is not the same as improving vision. According to the online World Carrot Museum which exists the British government began touting carrots' health benefits during World War II to lure consumers away from rationed foods. Part of that campaign emphasized vitamin A's role in seeing in the dark. From the campaign, the myth grew that carrots improved already-healthy vision in the dark for example, during blackouts. That claim is false, according to Harvard Health Publications.

"Vitamin A will [help] keep your vision healthy; it won't improve your vision," Taylor says. "It won't keep you from needing glasses or contacts."

There's one more catch to vitamin A's powers. Because vitamin A is a fat-soluble vitamin, one needs to eat it with fat in order to fully absorb it and its benefits. Eating a raw carrot won't deliver as much vitamin A punch. "That's why you need to dip it in ranch," quips Taylor.

Because the process of converting beta carotene to vitamin A is somewhat inefficient, the National Eye Institute's Redmond says it's important to eat orange-colored foods frequently, as well as other foods with vitamin A, like dairy and fish.

To make nourishing the eye easier, Taylor recommends an ideal plate for healthy vision. Most of the plate would be taken up with a spinach and kale salad, red peppers, almonds and carrots on top good sources of vitamin A, E and C, all of which support eye health. An oily dressing helps with intake of fat-soluble vitamins A and E. (Some hard-boiled eggs would also add carotenoids that protect vision, as well as fat to help absorption.) On the side, kiwi and oranges provide vitamin C, and fish like swordfish or salmon offer zinc, another key ingredient for eye health.

But if that doesn't tickle your fancy, Taylor recommends a favorite from childhood. "I used to grow carrots with my daddy in the garden," Taylor says. "Try roasting carrots, parsnips, beets and fingerling potatoes with olive oil, rosemary and sea salt. ... Life just doesn't get better than that."

The Eyesight of Dogs – Good Herald

June 5th, 2017 6:43 am

Dogs are said to have the ability to see spirits and other paranormal entities unseen by man. In spite of this ability, vision is said to be the least sensitive sense of a dog. Our four legged friends are noted to have excellent hearing abilities and ultra sensitive noses but vision of dogs is inferior to that of its human friends.

So what kind of vision do dogs have? In spite of the similarity in genetics, dogs vision is different from humans. There was once a theory that dogs are living in a colorless world as they do not have the ability to see colors. Studies have proven that dogs can see colors but unlike humans that have trichomatic vision, dogs are noted to have dichromatic vision. Due to the dichromatic vision, dogs can only see some colors in the spectrum. Although not scientifically verified, dogs are believed to be able to see only shades of yellow and blue. Because dogs have fewer photoreceptor cones, mans best friends do not have the ability to distinguish red and orange colors.

Dogs see better in dim lights. This ability enables dogs to hunt and capture prey even in the night. Running in the dark at high speed would not be a problem to dogs because of their ability to see in the dark. Dogs make dependable guards not only because of their alert and protective nature but also because of this night time vision. Dogs can see better in the dark because they have the ability to dilate the pupils to let more light in.

Behind the dogs retina is a layer of reflective cells known as tapetum lucidum that has the function of reflecting light so that object the dog see in the dark would appear to be well lighted. Dogs have a more accurate and developed wide angle vision and peripheral vision. Dogs can detect the slightest movement even at a distance.

Dogs though find it hard to focus on the shape of object because they are known to have low visual acuity. These animals can detect movements at a distance but they would not be able to distinguish the shape of the moving object. Dog can see distant movements but objects that can be seen clearly by humans as far as 75 feet will be seen by dogs clearly if the object is only 20 feet away

Dogs indeed see the world in a different manner. Even with its inferior vision, dogs still have the qualities that make them endearing pets.

Now that you have read some about how dogs see. How about learning more about related topics like can dogs see colors? Sarahs Dogs answers this and many other questions about dogs.

Tour de Cure raises money for diabetes prevention – NEWS10 ABC – NEWS10 ABC

June 5th, 2017 6:43 am

SARATOGA SPRINGS, N.Y. (NEWS10) Cyclists took over the Spa City today for the 2017 Saratoga Tour de Cure.

Its one of the biggest events in the Capital Region to raise awareness for diabetes, taking place at Saratoga State Park.

All these cyclists here to raise money for diabetes research, the heroes of the event are the ones donning red.

To get that many people out here to show support its just overwhelming, said Randy Lewis of Clifton Park.

For the past seven years, Type 1 diabetes patient, Lewis has biked in Saratogas Tour de Cure.

His family was there to cheer him on.

Two years ago, his youngest daughter joined him on the ride, when she too was diagnosed with the disease.

Even though Ive watched my dad for 24 years, grow up with this disease, I honestly thought my life was over, said Sydnie Lewis.

Around 1500 cyclists, some riding as far as 100 miles came to show support at the event.

This was an emotional day for the Red Riders, people who are biking with Type 1 or Type 2 diabetes.

Crossing the finish line the first time, I did it, I had tears in my eyes, said Red Rider, Jen Edmiston.

Ben Heidbreder, a 13-year old trained for months to bike 50 miles with his dad.

Very proud of him he raised over $2,300 for diabetes research. Hes a champion rider, said Jeff Heidbreder of his son.

The event is something Sydnie and her father look forward to every year.

A reminder that life can be a tough ride, but youre never alone.

Theres so many people around you whether have it or they know someone or they just know of the disease. You have a huge support group no matter where you go, said Sydnie Lewis.

The goal is to raise $1.1 million and all proceeds go towards mission of American Diabetes Association, to prevent and to cure diabetes.

The Real World, Diabetes: As cameras roll, patients seek healing – STAT

ONTEGO BAY, Jamaica The man who boasts ofchanging the face of diabetes spreads his arms out wide, like the Christ the Redeemer statue, but in neon orange shorts and bare feet. He looks earnestly into the rolling camera.

Welcome to Reversed, he intones. Seated behind him are four of his disciples: Americans with type 2 diabetes whove flown to this tropical beach town to participate in a reality TV show marketed as a momentous opportunity to restore their health.Over eight days, theyll learn to exercise and eat right and bare their struggles in cathartic therapy sessions.

Their host, Charles Mattocks, is a smooth-talking, fast-moving entrepreneur, who has leveraged his family fame (his uncle was Bob Marley) and his own medical history (he uses diet and exercise, not insulin, to manage his diabetes) to set himself up as a guru to diabetics everywhere.

In an age where nearly 1 in 10 Americans has diabetes, a disease that can bring a lifetime of painful complications, patients are often desperate for miraculous turnarounds and theres a booming trade in supplements, diets, and self-help books that promise answers. Now, theres a TV show, too.

But Reversed is unlikely to prove anyones salvation.

The show,which will begin airing next month on cable, is at once a vehicle for Mattocks to proselytize his gospel of self-help, a marketing gambit by a pharma company thats running out of money, and a season-long advertisement for a luxury getaway at the sparkling resort where it was filmed.

The carefully choreographed, relentlessly upbeat atmosphere cultivatedunderthe Jamaican sun feels, well, unreal. Back at home, the shows stars like the viewers expected to tune in dont have in-house chefs to cook them healthy meals or mentors toguide them through yoga lessons.

Instead, theyre grappling with the stubborn realities and compounding challenges so common inpatients with chronic disease: deteriorating vision, nerve damage in their feet,congestive heart failure, hypertension, high body fat, the inability to work and even to walk. Just before the show, one of the participantslost her home; two others, a married couple, had been relying on food banks because they hadnt been able to afford to go to a grocery store for months.

Mattocks, the shows executive producer and creator, said he originally imagined Reversedas The Biggest Loser meets diabetes a reference to the long-running weight-loss competition on NBC.

But the participants on Reversed arent competing. Judging from the two days of filming that STAT observed, the show has more in common with the reality TV tradition of putting a bunch of strangers in a house together and seeing what happens. Call it The Real World: Diabetes, featuring burned kale chips, frowned-on cigarette breaks, and one participants dramatic decision to quit the show. (I dont think he was coming here for the right reasons at all, Mattocks told STAT, borrowing the ultimate reality TV insult.)

So it went for the weekof filming, as Mattocks put his cast members through a quirky array of activities:There were massages, just steps from the glittering Caribbean. Trust exercises featuring blindfolds, a basketball, and a banana. Lessons about natural remedies and medicinal plants on a day trip to a nearby farm.

Where are all the new diabetes drugs?

The camera operators scurried on instinct toward any hint of drama or tears. And they didnt always abide by the shows lessons for good health: At lunch one day, for instance, the diabetics ate seasoned vegetablesand sipped water while some crew members chowed on hamburgers and swigged from plastic bottles of Ting, a sugary citrus soda popular in the Caribbean.

The debut 10-episode season airs this summer on Discovery Life, a cable channel that specializes in medical programming starring real people, like The Boy With No Brain and Untold Stories of the ER. Last year it drew an average of 88,000 viewers a night during prime time, according to Valeria Almada, a spokeswoman for the channel. That ranks around 97th among networks, by one recent estimate of viewership.

The shows primary sponsor is MannKind, an insulin manufacturer thats in bad financial shape. Neither the show nor the company would say how much the sponsorship cost, but MannKind willget advertising spots for its struggling insulin inhaler, Afrezza, during commercial breaks and perhaps a brief mention of the product on the show itself.

Mattocks makes a point of telling STAT that hes not promising anyone they can reverse their diabetes. But he has, in the past, said exactly that.

And one of the sponsors of his show expressly promised that, too on camera. The company, OneCare, makes software to help patients manage their diabetes. And in exchange for his $6,000 sponsorship, CEO Gary Austin got to film a segment on set in Jamaica in which he explains to the cast members how his product works and tells them it will help them vanquish diabetes. Its possible, he told them. You can reverse it.

Three of thepatients Mattocks recruited for the show are convinced.I truly believe that within the next year I will no longer be called a diabetic, said Lisa Campbell, cheerful and effortlessly expressive in her Southern drawl.

I truly believe that within the next year I will no longer be called a diabetic.

Lisa Campbell, cast member

At 54, she has a litany of health complaints so severe, they forced into retirement from her career as an elementary school teacher four years ago. Her right foot isswollen and her ankle deteriorated from complications ofdiabetic nerve damage, known as neuropathy. Her vision is so blurred by retinopathy that she recently went blind for four months. To get around her home near Atlanta, she juggles between a wheelchair, walker, and cane.

Her 49-year-old husband, Roger, who joined her on set, has also been ravaged by diabetes: His left leg was amputated a few inches below the knee in 2015 and shortly before the filming, hedbeen diagnosed with congestive heart failure. Hed also developed a wound on his stump, but didnt tell his doctor because he suspected hed get hospitalized and have to skipthe trip, his first ever out of the country. He refused to miss it.

For patients with such advanced conditions, the hope of vanquishing diseaseis often an unrealistic one. And criticsworryReversedwill add fuel to aflourishingcottage industry premised on the idea that diabetes can be reversed.

You can manage it. You can control it. You cant reverse it. All this talk about reversing diabetes is a huge load of BS, said David Kliff, who has type 1 diabetes and publishes the newsletter Diabetic Investor.

To be sure, diabetics, like everyone else, can only benefit from a healthy diet and exercise. But theres no cure for diabetes. Type 1 diabetics cant quit their medicine, ever. And its extremely difficult for type 2 diabetics to do so, barring bariatric surgery. More than 2,200 such patients went on an intense diet and exercise regimen for a studypublished in 2012; after one year, only 11.5 percent were able to get off their medicine or get their blood sugar levels down to a certain threshold. After four years, just 7 percent were still there.

The whole reversed idea is: run screaming from the meds, said Amy Tenderich, a vocal patient advocate with type 1 diabetes. She worries that it might send the wrong message that if you continue to need medication or have to go on insulin, that you have failed.

Rick Phillips, a blogger with type 1 diabetes, shares that concern. He wrote inablog postthat he saw the TV shows title as an affront,the latest in a line of rhetoric that blames diabetics for their own disease. He cited recent comments from White House budget director Mick Mulvaney suggesting that American taxpayers shouldnt have to pay for the health care of the person who sits home drinks sugary drinks, and doesnt exercise, and eats poorly, and gets diabetes.

Mattocks did not take kindly to Phillipss critique of his show. Instead, he jumped on Twitter to call Phillips irrelevant and a clown. He added: Go be miserable some other place.

Mattocks insists that his show demonstrates its possible to slow the progress of the disease by reversing the way patients live their lives. He brought ahandful of experts onto the set to dispensetips about healthy habits, like how to read nutritional labels on breakfast cereal and how to tell if blood sugar levels are in a safe range.

He also sought to effectively scare his stars straight.Cast memberswere taken on a day trip to a dialysis center and a diabetes clinic in Kingston, Jamaicas capital, where they gaped at local patients in the advanced stages of diabetes.

You can manage it. You can control it. You cant reverse it. All this talk about reversing diabetes is a huge load of BS.

Then there wasthescene filmed on Day 6: Participants had toput on baggy jeans, a long belt, and a big checkered shirt using only one hand a challenge meant to show them what daily life is like for patients whove lost limbs due to complications from advanced diabetes.

Roll sound. And action!

Margie Rivera, a bubbly grandmother from Tampa, Fla., went first, though she hardly needed the exercise to introduce her to the debilitating effects of diabetes. She lost her job as a dialysis technician a year ago after diabetic retinopathy eroded her vision. Just before filming began, another blow: She and her husband lost the house they had been renting with intent to buy.

Now, Rivera, 53, used her teeth to get the big shirt on. The pants went on easily enough until she struggled to lace the belt through the belt loops. God, this is hard, she murmured.

Next up was Jerome Hughes, a 43-year-old former retail manager from Atlanta whos quick to crack jokes. He had the bright idea of lacing the belt through the pants before putting them on. But he struggled mightily to get the bulky denim up over his black high-top shoes. As he grew more and more frustrated, Mattocks put a supportive arm over his shoulder and stepped in to help. Hughes struggled some more with the shirt, never getting it fully on, until Mattocks marched him away from the cameras. Both of their faces were creased with emotion.

Everyone on this show has been reversed, Mattocks later told STAT. Mentally, physically, emotionally, and even spiritually in a sense.

Mattocks, 46, is the opposite of what youd expect Bob Marley to be like. Tightly wound and usually multitasking, Mattocks buzzes around his set, always intentional and in control. He talks in real life in much the same way he does on camera: in a quiet and soothing voice, peppering his speech with phraseslike healing and journey and changing lives.

Mattocks only met his famous uncle twice, in brief encounters as a child. But the reggae legend has been his inspiration to make a difference in this world, he said.

He started out as a rapper and actor, then turned to cooking, branding himself as The Poor Chef demonstratinghealthy meals that could be made for just $7.

Mattocks was diagnosed with type 2 diabetes at age 38. His doctor gave him no guidance about lifestyle changes, he said. But on his own, he was determined to turn his health around. He stopped bulking up in the gym. He started walking, and then running. He stayed away from fried foods. He lost about 20 pounds in 2 1/2months.

Once-promising diabetes breakthrough comes unglued with a major retraction

Mattocks never went on insulin, and spent just nine months on metformin before his doctor advised him he could stop, he said.

That led to yet another career pivot: He became an evangelist for managing diabetes.

To that end, he vouched foran energysupplement aimed at diabetics. He wrote a childrens bookabout a furry diabetic bear named Charlie B. Marley. At one point, he even created a sugar-free chocolate bar infused with coconut oil and called it the Charles Bar.

Mattocks, who lives in Tampa, was careful when he talked to STAT about his journey: He made clear that he has not reversed his own diabetes but simply has it under control. But hes been much more aggressive about dangling the promise of reversal in other public outreach.

What if I told you that you could reverse your diabetes? he wrote in a 2015 op-ed.

And in the trailer for his documentary The Diabetic You: We did it, he says, We proved that diet and exercise, lifestyle changes, you can reverse diabetes. Then he breaks down with emotion, hand over his eyes, as the screen turns to black.

His swaggering confidence in his ability to tame a chronic diseasecomes across especially clearly in the recently released first issue of his new Reversed Magazinefor diabetics. Hes listed as chief editor.

Its in large part a tribute to himself, an Oprah magazine with lower production standards and more self-flattery.

Mattocks poses on the cover wearing a cowboy hat, bandanna, and a big-buckled belt. The tagline: Theres a new sheriff in town. Under that: Charles Mattocks changes the face of diabetes. An article inside says we must admire Charles Mattocks.

There were no auditions for Reversed.Mattocks picked the five stars of his show by plucking out old friends and friends of friends with an eye toward appealing to a broad audience. (Shes going to be great for the Latin American community, he said of Rivera, who was born in Puerto Rico.)

In the spirit of marriage boot camp reality shows, the producers put the Campbells on camera together as much as possible.Theyre a match of opposites Lisa lively and talkative; Roger, quiet and concise and that dynamic was on display duringon-camera therapy sessions, trust exercises, and cooking scenes.

With cameras rolling and the on-set dietician murmuring encouragement, the couple tore kale into strips, sprinkled on some olive oil, and gently massaged the oil into the leaves during one such scene. Lisa chattered happily about how much she loves preparing kale chips. Roger, who used to manage a paint store before his worsening health put him on disability, dutifully lowered the pan layered with kale stripsinto the oven.

(That was acting. I made them just for the camera. I do not like them, he later confessed to STAT.)

The crew moved on to the next shoot helping Rivera prepare healthy ice cream made from frozen strawberries and bananas.

Then a producer jumped in. Theyd forgotten about the kale chips!

Sure enough, they were burning in the oven. Much of the batch was charred to a crisp.

The setting was undeniably gorgeous: Most of the show was filmed in a 14-bedroom villanestled in lush green hills, with aglistening turquoise swimming pool out backand, far below, the ocean.

Still, the filming wasnt always easy for the Campbells. After Lisa took a tumble walking up an outdoor ramp, she mostly stuck to a wheelchair on set. For his part, Roger had experienced an alarming low blood sugar episode on Day 2of filming. He was often claustrophobic and felt too hot to sleep. And he needed frequent breaks to smoke. (Mattocks and the others gently chastised him about his cigarettesbut never asked him to stop.)

Despite it all, both he and Lisa made it to the shows graduation ceremony in the nearby resort town of Negril, where they donned black caps and gowns to acceptcertificates of accomplishment.

Just before the cameras started rolling, a crew member spotted a problem: a telltale green bottle of Ting, resting on a ledge. Get that soda out of the shot! he bellowed.

Mattocks is betting big on Reversed. Hes funding the project in part with his own savings, though he wouldnt specify how much. The shows total budget is very low, he said. Its more of a work of love, you know what Im saying?

To help pay the bills, Mattocks secured a few sponsors, including the struggling pharma company MannKind.

It was an unusual fit, given that Mattocks has long been a self-described outspoken critic of drugcompanies and their advertising. And, indeed, despite the sponsorship, the vibe on the Reversed setwas markedly anti-pharmaceutical.For a few days of filming, Mattocks brought in a health coach (a doctor who doubles as a naturopath and uses his website tosell supplements) to work with the cast members.

Everyone on this show has been reversed mentally, physically, emotionally, and even spiritually in a sense.

The diabetic stars of the show spoke in often bitter terms about their distaste for the drug industry and their desire to get off drugs for good.

We are naturally getting ourselves weaned off of this insulin, Lisa Campbell confidently told STAT.

In phone interviews nearly two months after returning home, three ofthe participants said they were on their way to reversing their diabetes. (Hughes, for his part, said he thought in terms of reversing his mindset.) They raved about their double-digit weight loss, their new diets packed with vegetables, and their reduced need for insulin. They were undaunted by the long odds they face in their quest to restore their health, saying that the mentoring they got on the show would give them an edge.

Even Roger Campbell, who hasnt managed to cut all of his unhealthy habits, speaks with pride about his progress. Sure, hes still smoking cigarettes, but hes down to half a pack a day, compared to a full pack a day before filming. And, yes, he hasnt given up soda completely, but hes replaced his bottle of Diet Coke every other day with a Coke Zero once a week. He credits those and other changes with cutting in half his use of insulin.

I actually feel like I am reversing my diabetes, Roger Campbell said. I hope to eradicate it completely.

Yet many of the challenges that shape their lives are unchanged: Roger Campbells congestive heart failure makes it hard for him to do much exercise. Lisa Campbell still struggles to see clearly and cooks her (newly healthy) breakfasts from her wheelchair. And money is still painfully tight. The couple remains reliant on food banks, where fresh produce can be limited.

Mattockss team recently released an pathos-heavytrailer for Reversed,which debuts at 7 p.m. on July 18.

Theres Rivera honing her arm muscles by stretching a resistance band. Hughes meditates, his eyes closed and hands clasped. Lisa Campbell splashesin the swimming pool. Gloved hands clean theopen wound on Roger Campbells leg stump. The cast member who quitwalksout the front door.

Five lives came for HOPE, banner text reads. Five lives will NEVER be the same.

New diabetes tech is coming. But will it make much difference?

Mattocks is already planning a second season. Another producer said theyrethinking about setting it in Latin America this time. Especially if next season we have a bigger budget and a bigger crew and a different location, I think we can rival any show out there, Mattocks mused.

In the meantime, hes begun marketing a new offering: a diabetes getaway, branded as the Reversed retreat, in the Jamaican resort house where the show was filmed.

For a week in September (just before the season finale of Reversed), instructors will be on hand to guide vacationers through the many of the same exercises the cast carried out for the cameras: early morning yoga. A juicing workshop. Group meditation.

The cost: up to $4,000 for the week, for those who spring for a private suite.

Airfare is not included.
