Human immunodeficiency virus type 2 (HIV-2) and simian immunodeficiency virus isolated from a macaque monkey (SIVmac) are assumed to have originated from simian immunodeficiency virus isolated from sooty mangabey (SIVsm). Despite their close similarity in genome structure, HIV-2 and SIVmac show different sensitivities to TRIM5α, a host restriction factor against retroviruses. The replication of...

Haemolytic disease of the foetus and newborn (HDFN) is a condition in which the lifespan of an infant’s red blood cells (RBCs) is shortened by the action of specific maternal immunoglobulin G (IgG) antibody. Rhesus (Rh)D haemolytic disease of the newborn is a prototype of maternal isoimmunization and foetal haemolytic disease. Although rare, the other blood group antigens capable of causing all...

Compulsory exposure to genetically foreign maternal tissue imprints in offspring sustained tolerance to noninherited maternal antigens (NIMA). Immunological tolerance to NIMA was first described by Dr. Ray D. Owen for women genetically negative for erythrocyte rhesus (Rh) antigen with reduced sensitization from developmental Rh exposure by their mothers. Extending this analysis to HLA haplotype...

background: rh (rhesus) is a highly complex blood group system in man deeply rooted in transfusion medicine. isolation of rhd from cord blod, cloning and expression of recombinant rhd antigen in bacterial expression system was the aim of this study. methods: total rnas were extracted from cord blood (o + ).  the quality of rna was determined by electrophoresis. in or­der to obtain coding sequen...

The function of the Rhesus (Rh) complex in the human red cell membrane has been unknown for six decades. Based on the organismal, organ, and tissue distribution of Rh proteins, and on our evidence that their only known paralogues, the ammonium and methylammonium transport proteins (also called methylammonium permeases), are gas channels for NH(3), we recently speculated that Rh proteins are bio...

Rh (rhesus) D is the dominant antigen of the Rh blood group system. Recent advances in characterization of the nucleotide sequence of the cDNA(s) encoding the Rh D polypeptide allow the determination of the Rh D genotype at the DNA level. This can be of help in cases in which red blood cells are not available for phenotyping, eg, when in concerns a fetus. We have tested three independent DNA ty...

OBJECTIVE To determine the frequency of ABO blood group and Rhesus (Rh) D antigen in the females of "District" Peshawar, Khyber Pakhtunkhwa Province, Pakistan. METHODS This cross-sectional study was conducted on 429 women having pregnancy induced hypertension, admitted in the three teaching hospitals of Peshawar, over a period of one year. Blood sample was collected from each subject after ta...

The objective of this study was to determine if the genes for the putative ammonia transporters, Rhesus glycoproteins (Rh) and the facilitated urea transporter (UT) were expressed during early development of rainbow trout, Oncorhynchus mykiss Walbaum. We predicted that the Rh isoforms Rhbg, Rhcg1 and Rhcg2 would be expressed shortly after fertilization but UT expression would be delayed based o...

Objective: To determine the A, B, O, AB blood group distribution and Rhesus (Rh) positivity rate of Sivas province, thus to know groups in our region use it a practical scientific manner when necessary. Method: The results total 50,441 individuals over age 18 who applied Cumhuriyet University Health Services Application Research Hospital for various reasons between 2018 2020 were analyzed retro...

INTRODUCTION: The ABO and Rhesus-D blood group systems are important widely used in humans for transfusion of components various medical conditions. purpose this study was to determine the distribution Rhesus D groups among donors at Karnali Academy Health Sciences, Teaching Hospital, Jumla, Nepal. MATERIALS AND METHODS: From July 2019 January 2022, a retrospective cross-sectional 800 conducted...
