intraperitoneal adhesion formation is a major cause of intestinal obstruction and inferlitity.previous abdominal or pelvic surgery are the most common causes of intraperitoneal adhesion formation.addiction to opium and moephine is not only an important social and individual problem in the world but also affects human physiology and immune system.this randomized double-blind study was designed t...

platelet activation and adhesion to the site of vascular injury is a dynamic process comprising reversible and irreversible phases. platelet adhesion typically occurs in a multi-step process similar to the selectin/integrin-mediated adhesion of neutrophils. this phenomenon is highly regulated and influenced by the cross-talk between platelets and injured endothelium. this cross-talk involves a ...

background: postoperative peritoneal adhesion bands are one of the most common complications caused by foreign material.   objective: to investigate the effect of colchicine on talc-induced peritoneal adhesion bands.   method: adhesion bands were induced in 30 short hair england guinea pigs by introduction of talc-saline solution (10 ml, 10%) into the peritoneal cavity.  afterwards, the pigs we...

background & objectives:  methicillin resistance staphylococcus aureus (mrsa) is one of the most important pathogens that causes several nosocomial and community infections. adhesion to surfaces and biofilm formation is considered main step in staphylococcal infection. the aims of this study were to determine presence oficaabcd genes and relation to the biofilm formation in of mrsa isolates...

Bacterial adhesion and biofilm formation on surfaces raises health hazard issues in the medical environment. Previous studies of bacteria adhesion have focused on observations in their natural/native environments. Recently, surface science has contributed in advancing the understanding of bacterial adhesion by providing ideal platforms that attempt to mimic the bacteria's natural environments, ...

An investigation of the friction and sliding wear of gray cast iron against chromium plated cast irons was carried out on a newly constructed reciprocating friction and wear tester. The tests were the first to be done on the test rig under dry conditions and at the speed of 170 cm/min, and variable loads of 20-260 N for a duration of 15 min. to 3 hours. The gray cast iron surfaces worn by a pro...

objective: acinetobacter baumannii (a. baumannii) has a good potential to colonize on various surfaces. as a virulence factor, adhesion to surfaces is the first step in colonization. the two-partner secretion system (tps) proteins are key factors for bacterial attachment. the purpose of this study is to identify and study the role of this family of proteins in adhesion of a. baumannii to human ...
