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...

Thirty of the 38 cases were the result of Rh sensitization, and eight were due to incompatibility in the ABO system. Prenatal Investptions. Pregnant women attending the health centres, which combine the functions of prenatal and infant welfare clinics, were examined routinely for Rh blood groups. The Rh-negative women were tested for Rh antibodies. Cases with Rh antibodies were invited to atten...

the malignant process is uncertain. Blood group antigens provide a convenient system for the study of changes related to malignancy. The structure of the ABO and Rh blood group antigens is well studied. They are present in almost all body tis sues; highly specific antisera can be produced, and various specific tests for these antigens exist (1, 4, 6, 10). ABO and D (Rh0) blood group antigen dis...

OBJECTIVE To document the distribution of the ABO and rhesus (Rh) blood groups in a random sample of Saudi students from the King Khalid University, Abha, Kingdom of Saudi Arabia, and to compare our results from that of other studies in the Kingdom and elsewhere. METHODS The subjects included in this study were 944 males from the southwest region of Saudi Arabia including Aseer, Jizan, and Na...

Background: This study was conducted to determine whether type 1 diabetes mellitus (T1DM) is associated with ABO & Rhesus (Rh) blood groups. Materials and Methods: This analytical cross sectional study was carried out on 77 patients suffering from T1DM and 96 healthy children less than 18 years old referring to Yazd Diabetes Research Center from April 2018 to May 2019. The ABO blood group and ...

The RH blood group locus from RhD-positive donors is composed of two closely related genes, RHCE and RHD, encoding the Cc/Ee and D antigens, respectively. The major Rh antigen, D, is serologically defined as a mosaic of at least nine determinants (epD1 to epD9), and the lack of expression of some of these D epitopes at the surface of variant red blood cells defines the D category phenotypes. In...

This study was undertaken to find out the trend of blood group distribution (ABO and Rh) among the 1310 Nepalese attended in Tribhuvan University Teaching Hospital and Nepal Medical College Teaching Hospital Kathmandu. The frequency of distribution of A, B, AB and O was 28.5%, 27.3%, 8.7% and 35.5% respectively. Only 0.8% of them were found to be Rh (-) ve. In this population of study, O (+) ve...

AIM Preeclampsia (PE) is a major cause of maternal and neonatal morbidity and mortality. There is a genetic component in the development of PE with estimated heritability around 0.47. Several studies have investigated the association between maternal ABO blood groups (OMIM 110300) and risk of PE, with contradictory results have emerged. Considering that there is no study in this filed from Iran...
