objective(s): staphylococcus aureus is an important bacterial pathogen responsible for a variety numbers of nosocomial and community acquired infections. biofilm formation is regarded as an important factor in the establishment of s. aureus infection. the contribution of the genetic background of s. aureus to biofilm formation is poorly understood. the aim of the present work was to genotype s....

The epithelial apical junctional complex (AJC) is an important regulator of cell structure and function. The AJC is compartmentalized into substructures comprising the tight and adherens junctions, and other membrane complexes containing the membrane proteins nectin, junctional adhesion molecule, and crumbs. In addition, many peripheral membrane proteins localize to the AJC. Studies of isolated...

Objective(s): The present paper aims to review the studies describing the interactions between HopQ and CEACAMs along with possible mechanisms responsible for pathogenicity of Helicobacter pylori.Materials and Methods: The literature was searched on “PubMed” using different key words including Helicobacter pylori, CEACAM and gastric.<br ...

t tight junctions (TJs), claudins with four transmembrane domains are incorporated into TJ strands. Junctional adhesion molecule (JAM), which belongs to the immunoglobulin superfamily, is also localized at TJs, but it remains unclear how JAM is integrated into TJs. Immunoreplica electron microscopy revealed that JAM showed an intimate spatial relationship with TJ strands in epithelial cells. In...

T HE multistep theory of tumorigenesis is now widely accepted. During the tumor development the genetic alterations are accumulated, oncogenes are activated, and tumor suppressor genes are inactivated. Recently, the interesting idea is emerging that some cell adhesion molecules, integral membrane proteins, may work as tumor suppressors (Hedrick et al., 1993). Most of these cell adhesion molecul...

The purpose of this study is to ascertain the relationship between complementary and alternative healthcare versus Traditional Healthcare. This study finds that all forms of alternative care looked at are complements to traditional forms of healthcare. We find that higher education and being married increase the likelihood of utilizing CAM. Furthermore it is shown that white people and females ...

Several membrane-bound molecules expressed at the surface of tumor cells have been shown to be released in a soluble form, thereby affecting cell-cell interactions by reduction of ligand densities. Moreover, since the binding domain of the soluble molecules often remains functional, proteolytic cleavage can also reduce the recognition of tumor cells by effector cells bearing the corresponding r...

Introduction: Psoriasis is an inflammatory skin disease in which abnormal individual immune reactivity plays an important role. Eselectin and P-selectin are adhesion molecules expressed on vascular endothelial cells in several inflammatory skin diseases, including psoriasis. The aim of the present study was to describe selected immunological changes, concerning adhesion molecules status (sEsele...
