Background and Aim: Previous studies have shown that some dyes used in photodynamic therapy (PDT) have a low pH and may cause root demineralization and remove the smear layer. This study aimed to assess and compare the effects of root biomodification with citric acid and PDT on the adhesion and proliferation of human gingival fibroblasts (HGFs). Materials and Methods: In this in vitro experime...

endothelial dysfunction is thought to be a central pathogenic feature in preeclampsia on the basis of elevated adhesion molecules. soluble forms of these molecules can be detected in plasma, and their concentrations are thought to reflect the degree of activation of a particular cell type. the aim of the present study was to compare the levels of soluble vascular cell adhesion molecule-1 (svcam...

Chitosan bears numerous properties, such as biocompatibility, biodegradability and non-toxicity making it suitable for use in different biomedical fields. Zinc (Zn) is required for fibroblasts proliferation and collagen synthesis as essential elements of wound healing. Its nanoparticles are well known for their capability to enhance wound healing by cell adhesion and migration improvement throu...

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...

  Background : Pseudomonas aeruginosa is one of important opportunistic pathogen, that cases serious infections . It produces many virulence factors, and this bacterium usually is resistance against antimicrobial agents.   Objective :The aim of this study was evaluate the effects of sub-MICs of essential oils of Mentha spicata and Cumminum cyminum on alginate production, biofilm formation, swim...

Background: Inflammation is involved in development, progression, and complications of atherosclerotic disease. Clinical studies have indicated that the level of monocyte chemoattractant protein 1 (MCP-1), IL-18, and adhesion molecules correlates with the severity of atherosclerosis and can predict future cardiovascular events. Experimental studies have shown pentoxifylline (PTX) reduces these ...

Among the intermolecular interactions, the Casimir and van der Waals forces are the most important forces that highly affect the behavior of nanostructures. This paper studies the effect of such forces on the adhesion of cantilever freestanding nanostructures. The nanostructures are made of a freestanding nano-beam which is suspended between two upper and lower conductive surfaces. The linear s...

objective: we introduce an rgd (arg-gly-asp)-containing peptide of collagen iv origin that possesses potent cell adhesion and proliferation properties. materials and methods: in this experimental study, the peptide was immobilized on an electrospun nanofibrous polycaprolactone/gelatin (pcl/gel) hybrid scaffold by a chemical bonding approach to improve cell adhesion properties of the scaffold. a...

aim : the present study evaluated the association between g241r and k469e polymorphisms of intercellular adhesion molecule 1 gene and inflammatory bowel disease in iranian population.   background : inflammatory bowel disease including ulcerative colitis and crohn’s disease, is a chronic idiopathic inflammatory disease of the gastrointestinal tract. there are two single base polymorphisms of in...
