9thInternational Conference on Hematology

Date: November 02-04, 2017

Venue: Las Vegas, USA

Hematology 2016 has been designed with many interesting and informative scientific sessions; it includes all possible aspects of Hematology research.

Hematology

Erythrocytesare also known as red blood cells which carry oxygen to the body and collect carbon dioxide from the body by the use of hemoglobin and its life span of 120 days. along the side the leucocytes helps in protecting the healthy cells because the W.B.C (leucocytes) act as the defending cells in protecting the immune system from the foreign cells. Theseleucocytesare multipotent cells in bone marrow and there life span is of 3-4 days where the yellow blood cells are called as thrombocytes they are where small and irregular in shape they have life span of 5-9 days they are mostly seen in mammals they help in clotting of blood which are in fibrin form called as thrombosis these lead to heart stroke, blockage of blood in blood mostly in arms and legs. where C.B.C is known ascomplete blood countis done to know the number of cells in a body these are mainly done by lab technician presently they are been tested by automatic analyzer the high and low amount of cells will lead to many diseases. Decrease of R.B.C in the body these causes of anemia which leads to weakness, feeling of tired, shortness of breath and person will be noticeably pale. Formation of blood cellular components are called as Hematopoiesis and all the cellular blood components are derived from hematopoiesis stem cells in a healthy individual nearly 10111012new blood cells are produced these help in steady peripheral circulation. If there is a increases of R.B.C in the body these causes polycythemia these can be measured through hematocrit level.

Blood Disorders

Hemophilia Ais a genetic deficiency in clottingfactor VIII,which causes increased bleeding and usually affects males. About 70% of the time it is inherited as an X-linked recessive trait, but around 30% of cases arise from spontaneous mutations. Hemophilia B is ablood clottingdisorder caused by amutationof thefactor IXgene, leading to a deficiency of factor IX. It is the second-most common form ofhaemophilia, rarer thanhaemophilia A. It is sometimes calledChristmas disease, named afterStephen Christmas, the first patient described with this disease.In addition, the first report of its identification was published in the Christmas edition of theBritish Medical Journal.Hemophilia C is a mild form of haemophiliaaffecting both sexes. However, it predominantly occurs in Jews ofAshkenazidescent. It is the fourth most common coagulationdisorder aftervon Willebrand's diseaseandhaemophiliaAandB.In theUSAit is thought to affect 1 in 100,000 of the adult population, making it 10% as common as haemophilia A. Idiopathic thrombocytopenic purpura(ITP), also known asimmune thrombocytopenia,primary immune thrombocytopenia,primary immune thrombocytopenic purpuraorautoimmune thrombocytopenic purpura, is defined as isolated low platelet count (thrombocytopenia) with normalbone marrowand the absence of other causes of thrombocytopeniaVon Willebrand diseasesis the most common hereditarycoagulationabnormality described in humans. Platelets also called "thrombocytes" areblood cellswhose function (along with thecoagulation factors) is to stop bleeding by clumping and clogging blood vessel injuries.Platelets have nocell nucleus: Coagulation is highlyconservedthroughout biology; in allmammals, coagulation involves both a cellular (platelet) and aprotein(coagulation factor) component and these are occoured due togenetic blood disorders

Hematologic Malignancies

Lymphatic leukemiawhich effect the white blood cells(w.b.c) they are closely related to the lymphomas and some of them are unitary diseases which related to the adult T cells leukemia these come under the lymphoproliferative disorders. Mostly they involve in the B-cell sub type lymphocytes. The myeloid leukemia is preferred to the granulocyte precursor in the bone marrow and spinal cord and these arises the abnormal growth in the blood from tissues in the bone marrow. They are mainly related to the hematopoietic cells and these sub title into acute and chronic lymphoblastic leukemia. The acute leukemia is that rapidly producing immature blood cells as they are bulk number of cells healthy cells are not produced in bone marrow due this spill over the blood stream which spread to other body parts. Where as in chronic leukemia highly bulid of matured cells are formed but still abnormal white cells are formed these can not be treated immediately mostly seen in older people. The cancer which originate from white blood cells are called as lymphoma and this disorder is mainly seen inHodgkin lymphomathese diseases is treated by radiation and chemotherapy, orhematopoietic stem cell transplantation. The cancer which starts with in the cell are called as Non Hodgkin lymphocytes and these lymphocytes are of lymph nodes. The bone marrow which develops too many white blood cells leads tomultiple myleoma. The further details on malignance are been discussed inHematology oncology conference-2015.

Hematology and immunology

Blood groupsare of ABO type and but at present the Rh blood grouping of 50 well defined antigens in which 5 are more important they are D,C,c,E and e and Rh factors are of Rh positive and Rh negative which refers to the D-antigen. These D-antigen helps in prevention of erythroblast fetalis lacking of Rh antigen it defined as negative and presences of Rh antigen in blood leads to positive these leads to rh incompatibility. The prevention treatment of diseases related to the blood is called as the Hematology. The hematologists conduct works on cancer to. The disorder of immune system leading to hypersensitivity is called asClinical Immunologyand the abnormal growth of an infection are known as Inflammation and the arise of an abnormal immune response to the body or an immune suppression are known as Auto immune disorder. The stem cell therapy is used to treat or prevent a disease or a condition mostly Bone marrow stem cell therapy is seen and recently umbilical cord therapy Stem cell transplantation strategies remains a dangerous procedure with many possible complications; it is reserved for patients with life-threatening diseases.

Blood Transplantation

Theumbilical cordis a conduit between the developingembryoorfetusand theplacenta. The umbilical vein supplies the fetus with nutrient-richbloodfrom theplacenta The hematopoitic bone marrow transplant, the HSC are removed from a large bone of the donor, typically thepelvis, through a largeneedlethat reaches the center of the bone. Acute myeloid leukemia is a cancerof themyeloidline of blood cells, characterized by the rapid growth of abnormalwhite blood cellsthat accumulate in thebone marrowand interfere withthe production of normal blood cells and the Thrombosis is the formation of ablood clot inside ablood vessel, obstructing the flow ofbloodthrough thecirculatory system. TheHemostaticis a process which causes bleeding to stop, meaning to keep blood within a damaged blood vessel this is the first stage of wound healing. Metabolic syndromeis a disorder of energy utilization and storage, diagnosed by a co-occurrence of three out of five of the following medical conditions, obesity,elevated blood pressure,elevated fasting plasma glucose,high serum triglycerides, and lowhigh-density lipoprotein(HDL) levels. Metabolic syndrome increases the risk developingcardiovascular diseaseanddiabetes.

Diagnosis and Treatment

Palliative careis amultidisciplinary approachto specialisedmedical carefor people with seriousillnesses The spleen, similar in structure to a largelymph node, acts as a blood filter. Anticoagulants(antithrombics) are a class of drugs that work to prevent thecoagulation(clotting) of blood. Some anticoagulants are used in medical equipment, such astest tubes ,blood transfusionbags, andrenal dialysisequipment. Anvena cava filteris a type of vascular filter, amedicaldevice that is implanted byinterventional radiologistsor vascular surgeons into theinferior vena cavato presumably prevent life-threateningpulmonary emboliistherapyusingionizing radiation, generally as part of cancer treatmentto control or killmalignantcells. Radiation therapy may be curative in a number of types of cancer if they are localized to one area of the body. The subspecialty ofoncologythat focuses on radiotherapy is calledradiation oncology. Translational research is another term fortranslated researchandtranslational science, Applying knowledge from basic science is a major stumbling block in science, partially due to the compartmentalization within science. Targeted drug delivery is a method of deliveringmedicationto a patient in a manner that increases theconcentrationof the medication in some parts of the body relative to others.

New Drug Development in Haematology

The development of antibiotic resistance in particular stems from the drugs targeting only specific bacterial molecules. Because the drugisso specific, any mutation in these molecules will interfere with or negate its destructive effect, resulting in antibiotic resistance. Known asDrug deliveryConditions treated with combination therapy includetuberculosis,leprosy,cancer,malaria, andHIV/AIDS. One major benefit of combination therapies is that they reduce development ofdrug resistance, since a pathogen or tumor is less likely to have resistance to multiple drugs simultaneously.Artemisinin-based monotherapies for malaria are explicitly discouraged to avoid the problem of developing resistance to the newer treatment. Drug Induced Blood Disorders causes of sickle cell anemia,pale skin non steroids antiinflammatory drugswhich causes ulcers Using drug repositioning, pharmaceutical companies have achieved a number successes, for examplePfizer'sViagrainerectile dysfunctionandCelgene'sthalidomidein severe erythema nodosum leprosum. Smaller companies, including Ore Pharmaceuticals,Biovista, Numedicus,Melior Discoveryand SOM Biotech are also performing drug repositioning on a systematic basis. These companies use a combination of approaches including in silico biology and in vivo/in vitro experimentation to assess a compound and develop and confirm hypotheses concerning its usage for new indications.

Hematology Research

Lymphatic diseasesthis is a type of cancer of the lymphatic system. It can start almost any where in the body. It's believed to be caused by HIV, Epstein-Barr Syndrome, age and family history. Symptoms include weight loss, fever, swollen lymph nodes, night sweats, itchy skin, fatigue, chest pain, coughing and/or trouble swallowing. Thelymphatic systemis part of thecirculatory system, comprising a network oflymphatic vesselsthat carry a clear fluid called lymph directionally towards the heart. The lymphatic system was first described in the seventeenth century independently byOlaus RudbeckandThomas Bartholin. Unlike thecardiovascular systemthe lymphatic system is not a closed system. The human circulatory system processes an average of 20 litres ofbloodper day throughcapillary filtrationwhich removesplasmawhile leaving theblood cells. Roughly 17 litres of the filtered plasma get reabsorbed directly into the blood vessels, while the remaining 3 litres are left behind in theinterstitial fluid. One of the main functions of the lymph system is to provide an accessory return route to the blood for the surplus 3 litres. Lymphatic diseases are ofNon-Hodgkin's Lymphoma, Hodgkins. Thethymusis a specialized primarylymphoidorgan of theimmune system. Within the thymus,T cellsor Tlymphocytesmature. T cells are critical to theadaptive immune system, where the body adapts specifically to foreign invaders.One of the example of lymph node development. Formation oflymph nodeinto the tumor which lead to cancer called oncology.

Various Aspects of Haematology

Pediatric Haematology and Oncologyis an internationalpeer-reviewedmedical journalthat covers all aspects ofpediatrichematologyandoncology. The journal covers immunology, pathology, and pharmacology in relation to blood diseases and cancer in children and shows how basic experimental research can contribute to the understanding of clinical problems. Physicians specialized in hematology are known ashematologistsorhaematologists. Their routine work mainly includes the care and treatment of patients with hematological diseases, although some may also work at the hematology laboratory viewingblood filmsandbone marrowslides under themicroscope, interpreting various hematological test results andblood clotting testresults. In some institutions, hematologists also manage the hematology laboratory. Physicians who work in hematology laboratories, and most commonly manage them, are pathologists specialized in the diagnosis of hematological diseases, referred to as hematopathologistsorhaematopathologists.Experimental Hematologyis apeer-reviewedmedical journalofhematology, which publishesoriginal researcharticles and reviews, as well as the abstracts of the annual proceedings of theSociety for Hematology and Stem Cells and they should be done under theHematology guidlines.

Blood Based Products

Ablood substituteis a substance used to mimic and fulfill some functions ofbiologicalblood. It aims to provide an alternative toblood transfusion, which is transferring blood orblood-based productsfrom one person into another. Thus far, there are no well-acceptedoxygen-carryingblood substitutes, which is the typical objective of ared blood celltransfusion; however, there are widely available non-bloodvolume expandersfor cases where only volume restoration is required. These are helping doctors and surgeons avoid the risks of disease transmission and immune suppression, address the chronic blood donor shortage, and address the concerns of Jehovah's Witnesses and others who have religious objections to receiving transfused blood.Pathogen reductionusing riboflavin and UV lightis a method by which infectiouspathogensinblood for transfusionare inactivated by addingriboflavinand irradiating withUV light. This method reduces the infectious levels of disease-causing agents that may be found in donated blood components, while still maintaining good quality blood components for transfusion. This type of approach to increase blood safety is also known as pathogen inactivation in the industry. Anartificial cellorminimal cellis an engineered particle that mimics one or many functions of abiological cell. The term does not refer to a specific physical entity, but rather to the idea that certain functions or structures of biological cells can be replaced or supplemented with a synthetic entity. Often, artificial cells are biological or polymeric membranes which enclose biologically active materials. As such,nanoparticles,liposomes,polymersomes, microcapsules and a number of other particles have qualified as artificial cells.Manufacturing of semi synthetic products of drugs are known as therapeutic biological products.Anticoagulants(antithrombics) are a class of drugs that work to prevent thecoagulation(clotting) of blood. Such substances occur naturally in leeches and blood-sucking insects.
