Background. Determination of Rh-affiliation is mandatory for donors and recipients, surgical patients, pregnant women, etc. There are variants the D antigen that difficult to identify by serological methods, example, a weak antigen.
 Aim. using genotyping in cases, when use methods does not allow obtaining reliable result.
 Material methods. We studied blood samples from (n=18), women...
BACKGROUND AND AIMS Seed quality may be compromised if seeds are harvested before natural dispersal (shedding). It has been shown previously that slow or delayed drying can increase potential quality compared with immediate rapid drying. This study set out to investigate whether or not there is a critical moisture content, below which drying terminates maturation events for seeds harvested afte...
The Rh system is the most polymorphic and immunogenic for all blood group systems. Currently more than 49 antigens were identified with five major antigens D, C, c, E, e. Knowledge of the Rh system's molecular basis, since its first cloning 17 years ago, allowed to understand the mechanism of Rh-negative phenotype and the variants of antigens as RHD and RHCE. Deletions, gene rearrangements and ...
OBJECTIVE To provide guidelines on use of anti-D prophylaxis to optimize prevention of rhesus (Rh) alloimmunization in Canadian women. OUTCOMES Decreased incidence of Rh alloimmunization and minimized practice variation with regards to immunoprophylaxis strategies. EVIDENCE The Cochrane Library and MEDLINE were searched for English-language articles from 1968 to 2001, relating to the preven...
چکیده سابقه و هدف سیستم گروه خون Rh یکی از پیچیده‌ترین سیستمهای گروههای خونی و دارای حدود 50 آنتی ژن است. دو ژن Rh D و Rh CE مسئول کد کردن آنتی‌ژن‌های سیستمRh هستند. فنوتیپ Rh null قادر به عرضه هیچ یک از این آنتیژنها نیست و شیوع آن یک در شش میلیون نفر است. می‌توان با تعیین فنوتیپ سایر افراد خانواده، خون مناسب را در موارد مورد نیاز تهیه کرد. مورد در سال 1392 خانمی 39 ساله با گروه A منف...
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...
A study of ABO blood group and Rh (D) factor, was carried out on 10478 cases. ‘0’ had the highest (35.13%) and blood group ‘AB’ the lowest (8.23%) frequency.Blood group 24.71% and 31.93%respectively. An overall 94.1 % of population was Rh (D)positive. Blood group A and B were A comparision of the ABO blood group and Rh(D) factor of the N.W.F.P., with that of Karachi population, shows that there...
Observations are described of the incidence among Caucasians and Negroes of the blood factors Rh(A), Rh(B) and Rh(C) which occur associated with the Rh(0) factor in typical Rh-positive blood. The antiserums used for the tests were derived from Rh-positive patients who had had hemolytic transfusion reactions or erythroblastotic babies. Among a large series of individuals, it was found that only ...
مالتیپل اسکلروزیس (ms) یک بیماری التهابی تخریب کنندهء میلین سیستم اعصاب مرکزی است که به ناتوانی حرکتی و اختلال در عملکرد حواس منجر می شود. این بیماری معمولا بین 20 تا 40 سالگی بروز می کند و میزان ابتلای زنان 2 برابر بیشتر از مردان است. در بین عوامل عفونی نقش ویروس و باکتری بخصوص ویروس اپشتین بار و باکتری pneumonia chlamydia در القای خود ایمنی و بروز ms مورد مطالعه قرار گرفته است. pneumonia chla...
