Hematology is the branch of medicine concerned with the study of the cause, prognosis, treatment, and prevention of diseases related to blood. It involves treating diseases that affect the production of blood and its components, such as blood cells, hemoglobin, blood proteins, bone marrow, platelets, blood vessels, spleen, and the mechanism of coagulation. Such diseases might include hemophilia, sickle cell anemia, blood clots (thrombus), other bleeding disorders, and blood cancers such as leukemia, multiple myeloma, and lymphoma. The laboratory analysis of blood is frequently performed by a medical technologist or medical laboratory scientist.
Lucy Wills, LRCP was an English haematologist and physician researcher. She conducted seminal work in India in the late 1920s and early 1930s on macrocytic anaemia of pregnancy. Her observations led to her discovery of a nutritional factor in yeast which both prevents and cures this disorder. Macrocytic anaemia is characterized by enlarged red blood cells and is life-threatening. Poor pregnant women in the tropics with inadequate diets are particularly susceptible. The nutritional factor identified by Lucy Wills was subsequently shown to be folate, the naturally occurring form of folic acid.
Nicosan, also known as Hemoxin, Niprisan, or Nix-0699, is a phytochemical which was studied in sickle-cell disease (SCD). As of 2017 it does not appear to be commercially available, as the only manufacturer, which was in Nigeria, has stopped producing it due to financial problems.
The Royal Society Africa Prize has been awarded by the Royal Society since 2006 to African-based researchers at the start of their career who are making innovative contributions to the biological sciences in Africa. £60,000 is awarded as a grant for the recipient to carry out a research project that is linked to an African centre of scientific excellence, normally a University or equivalent research centre, and a further £5,000 is given directly to the prizewinner.
Sickle cell disease (SCD), also simply called sickle cell, is a group of hemoglobin-related blood disorders typically inherited. The most common type is known as sickle cell anemia. It results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. This leads to a rigid, sickle-like shape under certain circumstances. Problems in sickle cell disease typically begin around 5 to 6 months of age. A number of health problems may develop, such as attacks of pain in joints, anemia, swelling in the hands and feet, bacterial infections, dizziness and stroke. Long-term pain may develop as people get older. The average life expectancy in the developed world is 40 to 60 years. It often gets worse with age. All the major organs are affected by sickle cell disease. The liver, heart, kidneys, gallbladder, eyes, bones, and joints also can suffer damage from the abnormal functions of the sickle cells, and their inability to flow through the small blood vessels correctly.

Graham Roger Serjeant is a British medical researcher who studied sickle-cell disease in Jamaica, setting up screening programmes and a cohort study from birth. He directed the MRC Laboratories at the University of the West Indies and instituted the Sickle Cell Trust (Jamaica), a local charity.
