Background: The objective of this study is to establish importance of anti-FSH antibodies in IVF outcome. Materials and Methods: This research was designed based on evaluation of several articles from 2000 till 2012 about anti-FSH antibodies in IVF outcome. Results: Serum concentrations of anti-FSH IgG and IgA were linearly associated with poorer ovarian stimulation outcome. For example 1.0 AU ...

The study have been done to detecting HRSV infections among hospitalized children under 10 years old in Salahaldin Governorate, addition compare different diagnostic methods for detection of this virus.
 Nasopharyngeal Swabs (NPS) and whole blood samples were taken from 400 between end August 2013, the May 2014, each sample was analyzed by Real time –PCR, IgM IgG specific determining speci...

Sera of localized juvenile periodontitis (LJP) patients colonized by Actinobacillus actinomycetemcomitans serotype b often contain markedly elevated levels of immunoglobulin G (IgG) antibodies to serospecific determinants in the O polysaccharide of lipopolysaccharide (LPS), as well as to outer membrane proteins of this species. IgG antibodies in LJP sera are known to opsonize A. actinomycetemco...

Background: Although in vitro fertilization (IVF) has been found to bypass the inhibitory effect of high levels of antisperm antibodies on sperm motility, fertilization rates are reduced in approximately 40% of the attempts. In this study, we investigated the relationship between antisperm antibodies measured by the direct mixed agglutination reaction (MAR) and the fertilization rate in inferti...

Background: Mild to severe post-transfusion adverse reactions have been reported in a proportion of immunodeficient patients receiving intravenous immunoglobulin (IVIg). Anti-IgA antibody has been proposed to be associated with development of such reactions. Objective: To assess the association between anti-IgA levels of different isotypes and adverse reactions induced in immunodeficient patien...

By using an indirect fluorescent antibody (IFA) procedure, we were recently able to demonstrate that a significant portion of natural antibody reactivity to Gram-negative bacteria resided in the IgG class as well as in the IgM class of antibodies (1). The magnitude of this IgG act ivi ty had apparently eluded detection in previous studies that used bactericidal, agglutination and other tests (2...

Heterophile antibodies in patients' serum may produce false increases in apparent analyte concentrations in "sandwich"-type immunoassays. Using three patients with endogenous anti-mouse IgG antibodies and a two-site mouse monoclonal assay for thyrotropin, we studied the ability of IgG fragments to block this positive interference. Mouse whole IgG and IgG Fc fragment blocked the interference vir...

background: patients with primary sjögren’s syndrome (pss) produce functional igg against cholinoreceptor of exocrine glands modifying their activity. the aim of the present work was to demonstrate pss igg antibodies (pss igg) interacting with m 3 muscarinic acetylcholine receptors (machr) of rats submandibular glands that alter mucin release and production via phospholipase c (plc) and cycloox...
