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...

Background and Aim: One of the main goals of blood transfusion medicine is to determine the compatibility of the blood products with the patients. Therefore, clinical and laboratory (serologic) evaluations should be done to determine the maximum compatibility (or minimum incompatibility). The most known blood groups is the ABO antigenic system and the most important of them is Rh system. Among ...

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...

ABO blood group system, a well-known genetic risk factor, has clinically been demonstrated to be linked with thrombotic vascular diseases. However, the relationship between ABO blood group and coronary artery disease (CAD) is still controversial. We here performed an updated meta-analysis of the related studies and tried to elucidate the potential role of ABO blood group as a risk factor for CA...

Pancreatic cancer is among the most aggressive types of cancer. It has mortality rates as the seventh most frequent cause of cancer death worldwide. The association between ABO blood group and risk of pancreatic cancer has been known for more than 40 years.Various studies, in detail, although conflicting on many occasions, on large population groups, cohort studies, case-control studies, retros...

MATERIAL AND METHODS 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 the ABO blood group.

Results: In this study, the following pattern of ABO blood groups was observed in IHD patients : blood group A 251 (27.67%); blood group B 329 (36.27%); blood group O 235 (25.91%); blood group AB 92 (10.14%). We found no relationship of ABO blood groups with age (p-value = 0.234), gender (p-value = 0.093), hypertension (p-value = 0.230), diabetes mellitus (p-value = 0.801), family history of IH...

von Willebrand factor (vWF) is synthesized exclusively by endothelial cells and megakaryocytes, and stored in the intracellular granules or constitutively secreted into plasma. ABO blood group antigens are covalently associated with asparagine-linked sugar chains of plasma vWF. The effect of ABO-mismatched bone marrow transplantation (BMT) or blood stem cell transplantation (BSCT) on the expres...

ABO blood groups and secretor status are important in clinical and forensic medicine and in relation to some diseases. There are geographic and racial differences in their frequencies, but the frequency of secretor status in different ABO blood group systems has not been determined yet. Therefore, the aim of this study was mainly to determine this point. Blood and saliva from 762 randomly selec...

BACKGROUND & OBJECTIVES There is lack of adequate information on the association between severe malaria and some human genetic markers like ABO blood types. The study was undertaken to evaluate the association between severe malaria infection and ABO blood types among febrile patients attending Felegeselam Health Center, northwestern Ethiopia. METHODS A total of 398 febrile patients were exam...
