background several factors may cause infertility and fetal loss. blood groups antigens seem to be implied in the mechanisms of infertility and fetal loss. maternal natural antibody can react against father’s blood group antigens on spermatozoa. the effects of parental blood group system on infertility and fetal surveillance perceived by its manifestation in prezygotic (caused infertility) and p...

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...

The role of the ABO blood group system in determining the outcome of bone marrow transplantation was investigated in 53 patients with aplastic anemia and acute leukemia grafted from HLA-identical siblings. There was no correlation between ABO compatibility and marrow engraftment, graft rejection, or graft-versus-host disease. In 5 recipients with antibodies prior to transplantation to antigens ...

A best evidence topic (BET) in cardiac surgery was written according to a structured protocol. The question addressed was whether ABO-incompatible (ABO-I) heart transplant recipients have a similar survival rate as an ABO-compatible (ABO-C) transplant in the pediatric population <1 year of age. Altogether more than 112 papers were found using the reported search, of which 10 represented the bes...

The editorial process of a scientific journal involves highly specialized skills and hard work of many con­ tributors, including editors and reviewers. These tasks require not only the intellectual competence of each but also hours of administrative work, evaluating manuscripts and maintaining the flow of publications in progress. The flow of the peer review process in ABO initiates through the...

The ABO blood group is the most important blood group system in transfusion medicine and organ transplantation. To date, more than 160 ABO alleles have been identified by molecular investigation. Almost all ABO genotyping studies have been performed in blood donors and families and for investigation of ABO subgroups detected serologically. The aim of the present study was to perform ABO genotyp...

ABO is the most clinically important blood group system in transfusion and transplantation medicine. The popular ABO genotyping methods, such as the sequencing of exons 6 and 7 and sequence-specific primer (SSP)-PCR, often lead to ambiguous typing results. Long PCR-sequencing method was designed to analyze two regulatory regions (promoter and CBF/NF-Y enhancer regions) and all genomic sequences...

BACKGROUND ABO blood typing in pre-transfusion testing is a major component of the high workload in blood banks that therefore requires automation. We often experienced discrepant results from an automated system, especially weak serum reactions. We evaluated the discrepant results by the reference manual method to confirm ABO blood typing. METHODS In total, 13,113 blood samples were tested w...

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...

Lossy trapdoor functions (LTDF) and all-but-one trapdoor functions (ABO-TDF) are fundamental cryptographic primitives. And given the recent advances in quantum computing, it would be much desirable to develop new and improved lattice-based LTDF and ABO-TDF. In this work, we provide more compact constructions of LTDF and ABO-TDF based on the learning with errors (LWE) problem. In addition, our L...
