ABO antigens are known to be oligosaccharide antigens, and are widely expressed on the membranes of red blood cells and tissue cells. Therefore, the determining ABO blood group antigens is important in both transfusion and organ transplantation, and is one of the markers used for personal identification in forensics. The ABO blood group is currently determined by the presence of A and B antigen...

Otkrićem ABO sustava krvnih grupa 1900. godine austrijski liječnik Karl Landsteiner utemeljio je transfuzijsko liječenje. Radom Yamamota 1990. klonirani su ABO geni, što je omogućilo naprednije strukturne i funkcionalne analize ABO sustava (1). Humani ABO gen smješten je na kromosomu 9 (9q34.1-q34.2). Sadrži 7 eksona i 6 introna koji obuhvaćaju 18 kb genomske DNA. Svaki tip krvne grupe sustava ...

BACKGROUND The aim was to elucidate clinical trial efficacy, safety, and dosing practices of abobotulinumtoxinA (ABO) treatment in adult patients with blepharospasm and hemifacial spasm. To date, most literature reviews for blepharospasm and hemifacial spasm have examined the effectiveness of all botulinum neurotoxin type A products as a class. However, differences in dosing units and recommend...

Lower levels of factor VIII and von Willebrand factor (vWF) have been reported in individuals with blood type O compared with individuals with other ABO blood types. However, this relationship has been demonstrated only by association studies and not by linkage studies. Also, it is not clear whether the ABO locus exerts a functional effect directly on these plasma factors or whether the ABO loc...

H uman leukocyte antigen (HLA) matching is critically important for successful hematopoietic progenitor cell (HPC) transplantation because the rates of engraftment and transplant outcomes are strongly influenced by the degree of match. This is largely because HLA antigens are expressed on immature pluripotent stem cells. In contrast, ABO incompatibility is not a barrier to successful HPC transp...

BACKGROUND Discrepant results in antigen and reverse ABO blood typing are often caused by a variant ABO gene. Molecular analysis can help to characterize such variants. Here, we describe the identification of a novel ABO gene variant in a patient with aberrant ABO phenotype and discrepant genotyping results. METHODS A patient with discrepant results in automated forward and reverse ABO phenot...

BACKGROUND Measurement of the ABO antibody (Ab) titer is important in ABO-incompatible transplantation. However, to the best of our knowledge, no standard protocol or external survey program to measure the ABO Ab titer has been established in Korea. We investigated the current status of ABO Ab titer measurements at various laboratories in Korea and the impact of the protocol provided to reduce ...

A clinicopathologic analysis of liver transplantation across major ABO blood group barriers was carried out 1) to determine if antibody-mediated (humoral) rejection was a cause of graft failure and if humoral rejection can be identified, 2) to propose criteria for establishing the diagnosis, and 3) to describe the clinical and pathological features of humoral rejection. A total of 51 (24 primar...

INTRODUCTION OnabotulinumtoxinA (ONA; Botox, Allergan, Irvine, CA) was discovered for cosmetic use in the mid-1980s for which it was FDA approved in April 2002. AbobotulinumtoxinA (ABO; Dysport, Valeant Pharmaceuticals International, Inc, Montreal, Quebec) was FDA approved in April 2009 for therapeutic and esthetic uses. The most recent studies make a comparison between the two formulations; ho...
