Antigens of the ABO blood group system (i.e., A, B, and H antigens) and Rhesus factor were discovered more than one century ago by karl & steiner [1,2] who is considering the father of transfusion medicine, and with this discovery he enabling physicians to transfuse blood without endangering the patient′s life. The ABO antigens are defined by carbohydrate moieties on the extracellular surface o...

Background: The ABO blood group system was the first human blood group system to be discovered by Landsteiner in 1900. The second type of blood group is the rhesus system. There are only two Rh phenotype such as Rh positive and Rh negative, depending on whether Rh antigen is present on the red cell or not. The frequency of ABO and Rh phenotypes in different populations has been extensively stud...

Blood group system was discovered way back in 1901 by Karl Landsteiner, Clinically, only ‘ABO’ and ‘Rhesus’ groups are of major importance. ABO blood group distribution varies in different geographical, ethnic and socio-economic groups. Apart from blood transfusion practice, knowing of the ABO and Rh blood groups were useful in population genetic studies, researching population migration patter...

Introduction The antigens of the ABO blood group system (A, B and H determinants, respectively) are complex carbohydrate molecules on the extracellular surface of red blood cells1. However, besides being expressed on red blood cells, ABO antigens are also strongly expressed on the surface of a variety of human cells and tissues, including the epithelium, sensory neurones, platelets, and the vas...

OBJECTIVE To analyze the frequency of and odds for and against HIV infection based on ABO blood type in a large sample of blood donors. BACKGROUND Coevolution between pathogens and hosts may explain the ABO system of polymorphisms. HIV-infected cells add ABO(H) blood group antigens to the viral envelope. Naturally occurring antibodies against ABO(H) antigens that are present in normal human s...

Abstract Background Hypertension is a major health problem, especially because it has no clear symptoms. It is strongly correlated with modifiable risk factors such as adiposities, age, stress, high salt intake. Overweight and obesity is conveniently determined from BMI and visceral adiposity is determined by waist circumference. ABO blood group is one such factor which needs to be investiga...

The ABO blood group was discovered in 1900 by Austrian scientist, Karl Landsteiner. At present, the International Society of Blood Transfusion (ISBT) approves as 29 human blood group systems. The ABO blood group system consists of four antigens (A, B, O and AB). These antigens are known as oligosaccharide antigens, and widely expressed on the membranes of red cell and tissue cells as well as, i...

BACKGROUND Data on frequency distribution of ABO-Rh blood groups in cardiac syndrome X (CSX) patients are not available. We aimed to investigate the distribution of ABO-Rh blood groups in these patients. MATERIALS AND METHODS A total of 247 CSX patients' records were reviewed in a cross-sectional study from 2006 to 2010. One hundred forty six patients (59.1%) were female, and the mean patient...
