In the ABO blood group system, there are three alleles: i, I A, and I B. As both I A and I B are dominant over i, only ii people have type O blood. Individuals with I A I A or I A i have type A blood, and individuals with I B I B or I B i have type B. Those with I A I B have type AB.
Triiodothyronine, also known as T3, is a thyroid hormone. It affects almost every physiological process in the body, including growth and development, metabolism, body temperature, and heart rate. [1]
The major form of thyroid hormone in the blood is thyroxine (T 4), whose half-life of around one week is longer than that of T 3. In humans, the ratio of T 4 to T 3 released into the blood is approximately 14:1. T 4 is converted to the active T 3 (three to four times more potent than T 4) within cells by deiodinases (5′-deiodinase).
The Lutheran antigen systems is a classification of human blood based on the presence of substances called Lutheran antigens on the surfaces of red blood cells. There are 19 known Lutheran antigens. [1] The name Lutheran stems from a blood donor's misspelled last name, reportedly named Lutteran or Lutheran.
The term human blood group systems is defined by the International Society of Blood Transfusion (ISBT) as systems in the human species where cell-surface antigens—in particular, those on blood cells—are "controlled at a single gene locus or by two or more very closely linked homologous genes with little or no observable recombination between them", and include the common ABO and Rh (Rhesus ...
For example, an individual can be AB, D positive, and at the same time M and N positive , K positive (Kell system), Le a or Le b negative (Lewis system), and so on, being positive or negative for each blood group system antigen. Many of the blood group systems were named after the patients in whom the corresponding antibodies were initially ...
The ABO blood group system is used to denote the presence of one, both, or neither of the A and B antigens on erythrocytes (red blood cells). [1] For human blood transfusions, it is the most important of the 44 different blood type (or group) classification systems currently recognized by the International Society of Blood Transfusions (ISBT ...
Warm antibody autoimmune hemolytic anemia ( WAIHA) is the most common form of autoimmune haemolytic anemia. [1] About half of the cases are of unknown cause, with the other half attributable to a predisposing condition or medications being taken. Contrary to cold autoimmune hemolytic anemia (e.g., cold agglutinin disease and paroxysmal cold ...
