A study of the incidence of Rh-sensitization showed a 6.5% incidence of anti-D appearing for the first time during the last trimester of pregnancy. In 24 of the 29 subjects these antibodies were weak, and were found only when a sensitive technique using enzyme-treated Rh-deletion test cells was employed. The remaining five, however, had high-titre antibodies, which were associated with a positi...

background multiple sclerosis (ms) is a demyelinating condition affecting the central nervous system. although the cause of this condition is unknown, patients with ms seem to have genetic vulnerability to certain environmental factors such as infection that could trigger this condition. objectives we conducted this study to determine whether ms risk increases following primary infection with e...

Anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis is a potentially fatal autoimmune syndrome in which IgG antibodies target the NR1 subunit of NMDA resulting profound dysregulation and neurotransmission.

non-enzymatic glycosylation of proteins is one of the key mechanisms in the pathogenesis of diabetic complications. glycation of igg is of special interest due to its possible influence on the functionality of immunoglobulins and overall immuno-competence. the aim of this study was to clarify more details of in vitro glycation of igg and to study the effect of this modification on its interatio...

BACKGROUND Toxoplasma gondii is one of the most common causes of latent infections in humans worldwide. Detecting anti-Toxoplasma antibodies in serum using serological tests is a common method to diagnose toxoplasmosis. OBJECTIVES In the present study, an indigenous ELISA kit was prepared using tachyzoites from the RH strain of T. gondii, and its sensitivity and specificity were compared with...

ABO; Blood groups; Population genetics; Rh (D) Abstract Background: Frequency distribution of blood groups is important as it is used in modern medicine, genetic research, anthropology, and tracing ancestral relations of humans. The ABO and Rh blood groups are the most important blood groups despite the long list of several other blood groups discovered so far. Aim of the study: To study and do...

Background and Aim: One of the main goals of blood transfusion medicine is to determine the compatibility of the blood products with the patients. Therefore, clinical and laboratory (serologic) evaluations should be done to determine the maximum compatibility (or minimum incompatibility). The most known blood groups is the ABO antigenic system and the most important of them is Rh system. Among ...

Background: RhD antigen system is the leading cause of hemolytic disease of the fetus and newborn (HDFN). Paternal molecular RhD zygosity test is valuable to decide on the use of anti-D immunoglobulin prophylaxis in Rh D-negative pregnant women. We aimed to investigate the paternal RhD zygosity by two molecular methods among blood donors in Kurdistan province, the west of Iran. We also compared...

Red cell alloimmunisation in pregnancy may result haemolytic disease of the foetus and newborn (HDN). During pregnancy, there are possibilities foetal antigen being exposed to mother’s circulation, thereby leading production antibodies. The immunoglobulin G (IgG) antibodies from mother pass through maternal surface placenta, which is then sensitised obstructs formation red blood cells (RBCs). T...
