Dr Pawan’s interests were many and varied. He was the author of numerous papers and studied such subjects as the water supplies of Trinidad; the histology of Aedes and Anophole (sic = Anopheles) mosquitos; sickle-cell anaemia; and the mosquito transmission of Venezuelan Equine Encephalomeyelitis Virus in Trinidad.
English: In sickle cell anemia, the Thymine nucleotide base on the DNA template strand is replaced with Adenine, which causes the mRNA to have a Uracil nucleotide instead of an Adenine one. This carries forward and during translation, instead of glutamic acid being added, a valine amino acid is instead added to the chain of amino acids, which ...
The acute chest syndrome is a vaso-occlusive crisis of the pulmonary vasculature commonly seen in people with sickle cell anemia. This condition commonly manifests with a new opacification of the lung(s) on a chest x-ray. [1]
Alpha-thalassemia (α-thalassemia, α-thalassaemia) is a form of thalassemia involving the genes HBA1 [5] and HBA2. [6] Thalassemias are a group of inherited blood conditions which result in the impaired production of hemoglobin, the molecule that carries oxygen in the blood. [7]
Other disorders which cause macrocytosis without DNA replication problems (i.e., non-megaloblastic macrocytic anemias), are disorders associated with increased red cell membrane surface area, such as pathologies of the liver and spleen which produce codocytes or "target cells" which have a central collection of hemoglobin surrounded by a pallor (a thin area) then followed by a thicker ...
Lovotibeglogene autotemcel, sold under the brand name Lyfgenia, is a lentiviral gene therapy used for the treatment of sickle cell disease. [1] [3] [4] [5]The most common side effects include stomatitis (mouth sores of the lips, mouth, and throat), low levels of platelets, white blood cells, and red blood cells, and febrile neutropenia (fever and low white blood cell count), consistent with ...
The three major types of inherited genetic resistance (sickle-cell disease, thalassaemias, and glucose-6-phosphate dehydrogenase deficiency) were present in the Mediterranean world by the time of the Roman Empire, about 2000 years ago. [19] Molecular methods have confirmed the high prevalence of P. falciparum malaria in ancient Egypt. [20]
The ESR is decreased in polycythemia, hyperviscosity, sickle cell anemia, leukemia, chronic fatigue syndrome, [4] low plasma protein (due to liver or kidney disease) and congestive heart failure. Although increases in immunoglobulins usually increase the ESR, very high levels can reduce it again due to hyperviscosity of the plasma. [5]
