aim : to evaluate the diagnostic value of helicobacter pylori stool antigen test before and after eradication background : there are different methods for diagnosis and follow up of helicobacter pylori infection, including invasive methods done with endoscopy and non invasive ones such as ubt and urine analysis antibody. one of non invasive new methods is analysis of helicobacter pylori stool a...

This work was designed to provide high protective, long-lasting immunity against FMD by enhancing the immunogenicity of trivalent vaccine using carbomer as adjuvant G. pigs an alternative cheapest animal model for quality control testing prepared vaccines formulae. Guinea were chosen experimental models develop concepts and techniques study PD50 because similarities clinical symptoms in these a...

Bone marrow stromal cell-2 (BST-2) has major roles in viral tethering and modulation of interferon production. Here we investigate BST-2 as a receptor for the delivery of antigen to dendritic cells (DCs). We show that BST-2 is expressed by a panel of mouse and human DC subsets, particularly under inflammatory conditions. The outcome of delivering antigen to BST-2 expressed by steady state and a...

background: cervical cancer is one of the most common types of women’s reproductive cancers. a major risk factor for cervical cancer is exposure to a group of common sexually transmitted viruses called human papillomavirus  (hpv). the over expression of hpv 16 i.e., e6 antigen in the tumors of suspected cervical cancer tissues. however e-6 antigen has hyaluronan binding protein site. methods: t...

Naturally evolving antibodies attain elevated affinity in germinal centers (GCs).[1] In these dynamic open micro-structures, competition between B cell clones and their somatic mutants drives an increase average across individual populations of up to a few thousand cells. Such evolutionary learning the antigenic target (known as maturation), however, eventually saturates. Most notably, saturati...
