The Kell blood-group antigen was originally reported to be a protein expressed in erythroid tissue only. Transcriptional analysis of the KEL promoter activity in human erythroleukaemia K562 and epithelial HeLa cells by electrophoretic mobility-shift and supershift assays, chloramphenicol acetyltransferase assays, co-transfection studies and site-directed mutagenesis provided the following resul...

BACKGROUND AND OBJECTIVES Blood incompatibility arises from individual and ethnic differences in red blood cell (RBC) antigen profiles. This underlines the importance of documenting RBC antigen variability in various ethnic groups. Central Asia is an area with a long and complex migratory history. The purpose of this article is to describe key antigen frequencies of Afghan ethnic groups in the ...

BACKGROUND & OBJECTIVES Little data are available regarding the frequencies of the blood group antigens other than ABO and RhD in the Indian population. Knowledge of the antigen frequencies is important to assess risk of antibody formation and to guide the probability of finding antigen-negative donor blood, which is especially useful when blood is required for a patient who has multiple red ce...

BACKGROUND Molecular testing is more precise compared to serology and has been widely used in genotyping blood group antigens. Single nucleotide polymorphisms (SNPs) of blood group antigens can be determined by the polymerase chain reaction with sequence specific priming (PCR-SSP) assay. Commercial high-throughput platforms can be expensive and are not approved in China. The genotype frequencie...

Many different blood group systems, such as Rh, ABO, Kell, Kidd, Duffy, MNS, have been reported as causes of hemolytic disease of the newborn. Hemolysis due to minor blood group incompatibility in the fetus or newborn has been determined in isolated case reports. Here, we report a case of a patient who had received red cell transfusion due to severe Rh c and E incompatibility, leading to hemoly...

155 Abstract: Alloimmunization can be a significant complication of transfusion therapy in patients with thalassemia and hemoglobinopathies. The aim of this study was to investigate Rh and Kell antigens in patients with thalassemia major and in donors in Turkey. A total of 3061 donors and 155 thalassemic patients from three different blood donation centers in Turkey were the subjects of this st...

The mental decline of King Henry VIII from being a jovial, charismatic and athletic young man into an increasingly paranoid, brutal tyrant in later life, ever more concerned at his lack of one or more male heirs, has attracted many medical diagnostic theories. Previous hypotheses have included diabetes, syphilis and hypothyroidism, among others. However, these inadequately explain Henry's failu...
