1. The theory of six allelic genes is reviewed, using the new improved nomenclature, and data are summarized regarding the distributions of the eight Rh types among white and negro individuals in New York City. 2. Results are presented of tests for property Hr in a series of 239 white individuals and 49 negroes. Statistical analysis of these data yields results supporting Race and Taylor's hypo...

background: determining of gene frequencies of a, band 0 genes from abo blood group system and d and d genes from rhesus system are objectives of the present study. methods: the study was a cross sectional descriptive study. all the voluntary blood donors, 7361 people, attending to the hamadan, iran, blood bank during 1996 were studied. primary information from the sex of blood donors and their...

Since platelets possess A and B antigen, mismatched ABO platelets could, theoretically, become activated or hypofunctional by exposure to anti-A or anti-B antibodies found in transfused or recipient plasma. Following normal baseline platelet aggregation to adenosine diphosphate (ADP), platelets from normal donors of different blood types were incubated at 37°C for 10 minutes with 50μl of normal...

 Objectives: To demonstrate the prevalence of ABO blood groups with deep venous thromboembolism in Chinese Han population. METHODS A retrospective study was conducted between January 2010 and March 2015 in The First Affiliated Hospital of Shantou University Medical College in Chaoshan District of Guangdong Province in South China. Eighty nine patients with confirmed diagnosis of deep venous t...

Objectives This study aims at investigating the relationship between malaria and blood group types in east China. Methods Between 1 January 2011 and 31 March 2017, 99 malaria patients were enrolled for the study. Laboratory tests were conducted on their infection status and blood types. Clinical data of the participants were retrieved for analysis. Results There was no mortality during the ...

INTRODUCTION Recently, numerous studies have been carried out to explain the genetics and immunopathogenesis of Behçet's disease (BD). There is still insufficient understanding of its etiopathogenesis, but substantial genetic and immune system abnormalities have been suggested. Several studies have shown remarkable associations of ABO blood groups with various diseases. This study investigated ...

Vertebrate hematopoiesis first produces primitive (embryonic) lineages and ultimately generates the definitive (adult) blood. Whereas definitive hematopoiesis may produce many diverse blood types via a common multipotent progenitor, primitive hematopoiesis has been thought to produce only erythrocytes or macrophages via progenitors that are unipotent for single blood lineages. Using a variety o...

Background and Objectives: A blood distribution network orchestrates distribution of safe blood products to hospitals. Blood shortage and blood wastage are two important factors which may affect efficiency of blood distribution network. Service delivery time is another factor that refers to the time interval between blood request by a hospital and transfusing it to the patient....
