introduction: the aim of this study was to determine a proper cell line for adherance of helicobacter pylori and a suitable method for attachment of this bacteria to cell lines in vitro. material and methods: a total of 22 h.pylori strains,isolated from the antral biopsies of 49 patients with dyspepsia,gastritis,gastric ulcer,duodenal ulcer, etc., were evaluated by elisa(upr)to determine the di...
Background and Aim: Helicobacter pylori is the etiologic agent of chronic –active gastritis, gastroduodenal ulcers in humans, and a co-factor in the occurrence of gastric cancer and mucosa-associated lymphoid tumors, Adhesion of H.pylori to the gastric mucosa is a critical and also initial step in the pathogenesis of the disease. Bacterial adhesion inhibitory agents provide a novel pharmacologi...
objective(s):anodized treated titanium surfaces, have been proposed as potential surfaces with better cell attachment capacities. we have investigated the adhesion and proliferation properties of h9c2 cardiac myoblasts on anodized treated titanium surface. materials and methods: surface topography and anodized tubules were examined by high-resolution scanning electron microscopy (sem). control...
Background: The present study aimed at investigating the role of depression and attachment styles in predicting cell phone addiction. Methods: In this descriptive correlational study, a sample including 100 students of Payame Noor University (PNU), Reyneh Center, Iran, in the academic year of 2013-2014 was selected using volunteer sampling. Participants were asked to complete the adult attachme...
Cell-based biosensors have become a research hotspot in biosensors and bioelectronics fields. The main feature of cell-based biosensors is the immobilization of living cell on the surface of transducers. Different types of polymers which are used as scaffolds for cell growth should be biocompatible and have reactive functional groups for further attachment of biomolecules. In this work, the cel...

objective: to date, several scaffolds have been fabricated for application in bone tissue repair. however, there remains a need for synthesis of scaffolds with better mechanical properties, which can be applied to defects in weight-bearing bones. we constructed a composite ceramic bioscaffold of hydroxyapatite-alumina and silicon carbide (ha-al2o3- sic) to take advantage of the mechanical prope...
Introduction: As the ability to repair cartilage tissue in body is limited, finding a suitable method for cartilage regeneration has gained the attention of many scholars. For this purpose, scaffold structure and morphology, along with cell culture on it, can be a novel method to treat cartilage injuries, osteoarthritis. Methods: In this study, polyhydroxybutyrate (PHB) is selected as the scaf...

Background: Though plausible candidate adhesion systems have been identified, current knowledge of embryo-maternal attachment in human is limited by the inability to conduct well-controlled functional investigations. We have sought a viable medium-throughput model for the identification and functional assessment of molecular markers in the initial epithelial phases of implantation. An ideal mod...
