The ABO histo-blood group, the critical determinant of transfusion incompatibility, was the first genetic polymorphism discovered in humans. Remarkably, ABO antigens are also polymorphic in many other primates, with the same two amino acid changes responsible for A and B specificity in all species sequenced to date. Whether this recurrence of A and B antigens is the result of an ancient polymor...
In past and ongoing military conflicts, the use of whole blood (WB) as a resuscitative product to treat trauma-induced shock and coagulopathy has been widely accepted as an alternative when availability of a balanced component-based transfusion strategy is restricted or lacking. In previous military conflicts, ABO group O blood from donors with low titers of anti-A/B blood group antibodies was ...
background: determining of gene frequencies of a, band 0 genes from abo blood group system and d and d genes from rhesus system are objectives of the present study. methods: the study was a cross sectional descriptive study. all the voluntary blood donors, 7361 people, attending to the hamadan, iran, blood bank during 1996 were studied. primary information from the sex of blood donors and their...
BACKGROUND An association between the ABO groups and pancreatic cancer has been shown previously, group A being significantly commoner in affected patients. We conducted the present study to investigate the prognostic effect of ABO blood group on overall survival of pancreas cancer patients. METHODS Patients who were diagnosed between 2005 and 2010 with pancreas cancer at Ankara Numune Educat...
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...
Background: ABO incompatibility is the most common cause of immune hemolytic disease of the newborn (HDN) and in most cases is not dangerous. The present study aimed to determine the prevalence of ABO-HDN and its effects on neonatal blood parameters in a population of patients referred to some training hospitals in Iran. Materials and methods: In This cross-sectional study, All newborns (a tot...
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...
