The current work details the screening of about 100 isolates from various soil samples, from which 1 isolate was finally selected based on the productivity of cholesterol oxidase. Further biochemical identification tests and 16S rRNA gene sequencing identified this isolate as Streptomyces badius. A preliminary culture media optimization was carried out(More)
Increasing applications of microwave radiation are of great concern with regard to public health. Several studies have been conducted detect effects of microwave exposure genetic material leading to negative or questionable results. The Micronucleus (MN) assay which is proved to be a useful method for detection of radiation exposure-induced cytogenetic(More)
INTRODUCTION The purpose of this study was to compare the antimicrobial efficacy of sodium hypochlorite (SH) and calcium hypochlorite (CH) against Enterococcus faecalis (E. faecalis) using quantitative real-time polymerase chain reaction (qPCR) analysis and also to compare their cytocompatibility on L929 murine fibroblasts using Mossman's tetrazolium(More)
Cellulases are important glycosyl hydrolase enzymes, which break down cellulose to β-glucose. They have been used widely in biotechnological processing such as bioethanol production. In this work we studied maximizing cellulase production by Bacillus sp. BCCS A3 using response surface methodology (RSM). A good result was attained with these conditions (%(More)
Today, mobile phones are used frequently and held close to the body. It is believed that microwaves may interfere with the cellular signaling systems, affecting the mechanisms by which the cells balance their functions. The objective of this work is the evaluation of the influence of different intensities of 950 MHz cell phone electromagnetic field (EMF) on(More)
BACKGROUND Now-a-days, children are exposed to mobile phone radiation at a very early age. We have previously shown that a large proportion of children in the city of Shiraz, Iran use mobile phones. Furthermore, we have indicated that the visual reaction time (VRT) of university students was significantly affected by a 10 min real/sham exposure to(More)
In this study we aimed to isolate and identify bacteria showing high keratinolytic activity from different sources of decomposed poultry waste and soil in Shiraz, Iran. Initial screening identified 30 bacteria showing high proteolytic activity, which were selected for transfer to basal feather medium using feathers as the sole source of carbon, nitrogen and(More)
OBJECTIVE To evaluate the effect of fibrin perihepatic packing on controlling liver hemorrhage and liver wound healing. METHODS In this animal experimental study, 20 adult male Sprague Dawley rats, weighing 200-220 g, were included. Stab wound injury was created by number 15 scalpel, so that bilateral liver capsules and liver tissue were cut, and acute(More)
BACKGROUND A potential treatment for healing hepatic tissue is delivering isolated hepatic cells to the site of injury to promote hepatic cells formation. In this technology, providing an appropriate injectable system for delivery of hepatic cells is an important issue. In this regard, fibrin scaffolds were designed with many advantages over other scaffolds(More)
