ABO blood type antigens are polymorphic, inherited structures presented on the surface of red blood cells. Although ABO blood group antigens is the most important antigens in transfusion medicine, its main role is not clearly clarified. Correlation between ABO blood group and susceptibility to certain infectious and non-infectious diseases is a controversial issue. Since, lack of blood type ant...

A glance at the table of contents of the British Medical Bulletin on Blood Groups reveals the complexity of the subject. It is a credit to the editor that he assembled a group of authors who not only know what to say but how to say it. This volume, short and to the point, provides a review of the newer developments in immunohematology which is suitable for students and practicing physicians ali...

Abstract We give a new characterisation of virtually free groups using graph minors. Namely, we prove that finitely generated, infinite group is if and only for any finite generating set, the corresponding Cayley minor excluded. This answers question Ostrovskii Rosenthal. The proof relies on showing generated excluded with respect to every set accessible, graph-theoretic accessibility due Thoma...

the aim of this study was to investigate the prevalence of hepatitis b, hepatitis c, hiv and syphilis infections in blood donors referred to tehran blood transfusion center (tbtc), and determine any association between blood groups and blood- borne infections between the years of 2005 and 2011.this was a retrospective study conducted at tbtc. all of the donor serum samples were screened for hbv...

abstract objective the history of the studies on blood groups dates back to early 20th century. more than 600 antigenic structures were detected among 29 blood groups. however, abo and rh antigenic structures were taken into consideration in transfusion medicine. frequency of the blood groups in a community helps the individuals in need and blood bank employees, which could be related to some d...
