ABO-incompatible transplants comprise up to 50% of allogeneic progenitor cell transplants. Major, minor and bidirectional ABO-incompatible transplants each have unique complications that can occur, including hemolysis at the time of progenitor cell infusion, hemolysis during donor engraftment, passenger lymphocyte syndrome, delayed red blood cell engraftment, and pure red cell aplasia. Appropri...
INTRODUCTION Inherited ABO blood groups have been shown to play possible contributions in the pathogenesis of various gynecologic and non-gynecologic carcinomas. With regard to gynecologic carcinomas, there is a confined number of studies that explored the relationship between ABO blood group and endometrial carcinoma (EC) in the PubMed-indexed literature. To the best of our knowledge, no such ...
The ABO locus in humans is characterized by elevated heterozygosity and very similar allele frequencies among populations scattered across the globe. Using knowledge of ABO protein function, we generated a simple model of asymmetric negative frequency dependent selection and genetic drift to explain the maintenance of ABO polymorphism and its loss in human populations. In our models, regardless...
BACKGROUND Detection methods for ABO antibody (Ab) titers vary across laboratories, and the results are different depending on the method used. We aimed to compare titer values using different detection methods for the measurement of ABO Ab titers. METHODS For ABO Ab detection, pooled group A or B red blood cells (RBCs) were reacted with each of 20 sera from blood groups A, B, or O without di...
The detection and quantification of potential genotoxic impurities (PGIs) play an important role in the pharmaceutical industry. The industry needs highly selective and sensitive analytical methods for trace level quantification of these PGIs in drug substances. A sensitive and stability indicating LC-MS/MS method was developed for the simultaneous detection and quantification of (S)-4-(4-amino...
This study aimed to investigate whether single nucleotide polymorphisms (SNPs) located near the gene of the ABO blood group play an important role in the genetic aetiology of menstrual disorders (MDs). Polymerase chain reaction-ligase detection reaction technology was used to detect eight SNPs near the ABO gene location on the chromosomes in 250 cases of MD and 250 cases of normal menstruation....
Many investigations have proved relations between ABO blood groups with some diseases and factor VIII and von willebrand level in plasma. In this study we investigated a relation between ABO blood groups and factor VIII and IX inhibitors in 102 patients with haemophilia A and 48 patients with haemophilia B. The assay of inhibitor was done by Bethesda method. There were no relation between ABO b...
Objective: To study phenotypic prevalence of ABO, Rh and Kell blood group system Material and Method: Voluntary blood donors were tested for red cell antigen of ABO, Rh (D, C, c, E, e) and Kell (K) blood group systems. Each sample was tested using LISS/Coombs ABO-Rh gel card and DiaClon Rh subgroups +K gel card. Calculations of antigen and phenotypes frequencies were expressed as percentages an...
The ABO blood group system plays an important role in transfusion and transplantation practices. Correct identification of the blood group of an individual is of paramount importance as minor errors can lead to fatal transfusion reactions. Weak expression of A, B and H antigens on the red cell surface can be inherited or acquired. They are probably the least frequently encountered and pose a ch...
The aim of this study was to investigate the serology and gene sequence characteristics of the A307 subgroup of ABO blood group. Monoclonal anti-A and anti-B antibodies were used to detect the ABO antigens of a proband whose positive blood type was not consistent with the negative blood type of ABO blood group. Meanwhile, standard A-, B-, and O-negative typing cells were used to test for ABO an...
