BACKGROUND & OBJECTIVES Indian population is characterized by the presence of various castes and tribal groups. Various genetic polymorphisms have been used to differentiate among these groups. Amongst these, the ABO blood group system has been extensively studied. There is no information on molecular genotyping of ABO blood groups from India. Therefore, the main objective of this study was to ...

OBJECTIVE To evaluate the correlations between the components of the Objective Grading System developed by the American Board of Orthodontics (ABO) and smile esthetics. MATERIALS AND METHODS The clinical photographs of 48 orthodontically treated patients were rated by a panel of 25 experienced orthodontists (15 men and 10 women) and 20 parents of orthodontic patients (eight men and 12 women)....

BACKGROUND Erythrocyte-magnetized technology (EMT) is a new fully automated method for ABO-RH-K phenotyping and antibody detection. The magnetization of red cells avoids centrifugation and washing phases. This report describes the results of an evaluation of this new technology on its specific automated system. STUDY DESIGN AND METHODS ABO-RH-K phenotyping was compared between EMT and a semia...

The ABO system is one of the major blood groups that have significant impact on blood transfusion and paternity testing. We have found a new ABO allele by analyses of the ABO genotype of the Taiwanese population. Exons 6 and 7 of the ABO gene were amplified by the polymerase chain reaction and analyzed by direct sequencing. The results indicated that the ABO gene in the Taiwanese population con...

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...

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...

In this study we analyzed the complete genomic sequences, except intron 1, and 2 regulatory regions of 6 common (ABO*A101, ABO*A201, ABO*B101, ABO*O01, ABO*O02, and ABO*O03) and 18 rare ABO alleles, 3 of which were new. This was done by phylogenetic analysis and correlating sequence data with the ABO phenotypes. The study revealed multiple polymorphisms in noncoding regions. The intron-based ph...

The clinical significance of ABO and Rhesus blood group systems has been well documented. The objective of this study was to determine the frequency of ABO and Rhesus blood groups in blood donors in Lahore, Pakistan, with a view to generate data with multipurpose future practicalities in the field of medicine. Blood groups of 3000 blood donors were determined by commercially available standard ...
