about 8% of the general population suffers from autoimmune diseases, from which 78% are women. one of the most important causes of thyroid diseases is autoimmunity in origin, and it seems that people with thyroid diseases present more signs of asthma. this study was therefore designed to investigate the frequency of autoimmune thyroid diseases in women suffering from bronchial asthma. in a cros...

background: in lupus nephritis (ln), deposition of pathogenic autoantibodies in the glomeruli is mediated via cross-reactivity with alpha-actinin. association of serum alpha-actinin antibody (aαa) with ln has been shown in a few studies but the results are controversial. methods: eighty patients into entered the study. the diagnosis of sle was confirmed according to the american college of rheu...

background: immunopathological and inflammatory processes play important roles in the initiation and development of ischemic heart disease (ihd). objective: the aim of this study was to evaluate the serum levels of several autoantibodies including rheumatoid factor (rf), anti-nuclear antibodies (ana), anti-small nuclear ribonucleoprotein (anti-sm), anti-phosphatidylserine (anti-ps) and anti-car...

Background: Invariant natural killer cells (iNKT) are an important immunoregulatory T cell subset. Currently several flow cytometry-based approaches exist for the identifi-cation of iNKT cells, which rely on using the 6B11 monoclonal antibody or a combina-tion of anti-Vα24 and anti-Vβ11 antibodies. Objective: The aim of this study was to compare the ability of two flow cytometry-based methods f...

background: human cd34 is a transmembrane glycoprotein which is expressed in human hematopoietic stem cells (hscs) and the small- vessel endothelial cells of a variety of tissues. cd34 plays a critical role as a marker for diagnosis and classification of leukemia. anti cd34 antibodies are used for isolation and purification of hscs from bone marrow, peripheral blood and cord blood. objective: t...

objectives: clinical laboratory health care workers can become infected through their occupation with blood-borne pathogens by percutanous injuries and mucocutaneous blood contacts such as cuts, needle sticks, splashes to mucous membranes or other body injuries. the purpose of this study was to determine the seroprevalence of, hepatitis c virus (hcv), and some of the risk factors in medical lab...

aim : this study was designed to evaluate the frequency of antibody against these viruses in individuals attending the endoscopy ward of taleghani hospital tehran, iran. background : blood-borne viruses such as hepatitis b and hepatitis c virus and htlv-1 virus are among the world’s public health problems. hepatitis viruses cause liver problems and htlv-1 infection can lead to adult t-cell lymp...

The purpose of the present study was to identify a potential interference of bovine herpesvirus-1 (BoHV-1) with sperm-oocyte interactions during bovine in vitro fertilization. An inhibition of almost 70% of sperm-zona binding was observed when bovine cumulus-denuded oocytes were inseminated in the presence of 10(7) 50% tissue culture infective dose/ml BoHV-1. The inhibitory effect of BoHV-1 on ...

The pars distalis of the tortoise, Geoclemis reevesii, was studied immunocytochemically with regards to its fine structure and distribution of different cell types. The pars distalis consists of cephalic and caudal lobes and a zona tuberalis, each with distinct cellular components. The cephalic lobe contains ACTH cells and prolactin (PRL) cells, while the caudal lobe consists of STH (GH) cells,...
