Apoptotic extrusion is a multicellular process utilized by live cells to remove neighboring apoptotic cells. In epithelial tissues, this process has been shown to be critical for the preservation of tissue integrity and barrier function. Here we demonstrate that extrusion is driven by the retraction of the apoptotic cell, which, in turn, triggers a transient and coordinated elongation of the ne...

conclusion our results showed that obtained protein patterns of the isolated strains were more reliable than serotyping results for typing purposes. our findings indicated that pap adhesion–encoding operon has an important role in the development and severity of uti. many cases of serious urogenital diseases are caused by a limited number of uropathogenic e.coli strains that generally possess s...

conclusions the impact of sugars and other factors on biofilm formation can vary depending on the type of bacteria present. results results showed that the presence of sugars has no effect on the bacterial growth rate; all three concentrations of sugars were hydrophilic and demonstrated a high affinity toward binding to the surfaces. background bacteria utilize various methods in order to live ...

Proteins are important in bacterial adhesion, but interactions at molecular-scales between proteins and specific functional groups are not well understood. The adhesion forces between four proteins [bovine serum albumin (BSA), protein A, lysozyme, and poly-d-lysine] and COOH, NH2 and OH-functionalized (latex) colloids were examined using colloid probe atomic force microscopy (AFM) as the functi...

Objective Bacterial adhesion is governed by specific and nonspecific interactions such as hydrophobicity. Hydrophobic interactions play a role in the adherence of microorganisms to a wide variety of surfaces and facilitate biofilm formation due to bacterial adhesion. In this article the relation between cell surface hydrophobicity and antibiotic resistance was studied. Materials and Methods ...

asthma is considered as a chronic inflammatory airway disease and defined as increased tracheobronchial responsiveness to variety of stimuli. edema and inflammatory cell infiltration in airway is observed in the asthmatic patients. one of the essential changes in inflammation is adhesion of leukocyte to endothelium and transmigration of leukocytes to the sites of inflammation. unfortunately, li...

objectives: postsurgical adhesion is one of the common complications after surgery. some anti-adhesion barriers are commercially available which are not customary used by physicians as much as expected because of ineffectiveness. recently, nanofibers have been introduced as anti-adhesion barriers with the potential of drug delivery. in the light of role of inflammation and oxidative stress in a...
