Some chemicals used by human such as food additives are mutagenic and mutagenicity effects analysis of them is very important because of considerable consumption by man. One of the most common methods used in the recognition of the chemicals' mutagenicity is Salmonella Typhimurium Reverse Mutation (Ames) test. The purpose of the present study is mutagenicity effects analysis of sodium nitrite, ...

background and objective: streptococcosis/lactococcosis is the cause of high morbidity and mortality in aquaculture sector and to date a number of species of streptococcus and lactococcus genera including s. iniae, s. agalactiae, s. dysagalactiae, s. parauberis, s. feacalis, l. garvieae and l. lactis have been discriminated as the cause of disease in aquatic animals. despite the use of diagnost...

<i>Ralstonia solanacearum</i> species complex (RSSC) is a soil borne plant pathogen causing bacterial wilt on various important crops, including Solanaceae plants. The pathogens within the RSSC produce exopolysaccharide (EPS), highly complicated nitrogen-containing heteropolymeric polysaccharide, as major virulence factor. However, biosynthetic pathway of EPS in has not been fully c...

OBJECTIVES Ginseng Rh2+ is enzyme-treated ginseng extract containing high amounts of converted ginsenosides, such as compound k, Rh2, Rg3, which have potent anticancer activity. We conducted general and genetic toxicity tests to evaluate the safety of ginseng Rh2+. METHODS An acute oral toxicity test was performed at a high-level dose of 4,000 mg/kg/day in Sprague-Dawley (SD) rats. A 14-day r...

AIDS is a global pandemic that has seen the development of novel and effective treatments to improve the quality of life of those infected and reduction of spread of the disease. Palmitic Acid (PA), which we identified and isolated from Sargassum fusiforme, is a naturally occurring fatty acid that specifically inhibits HIV entry by binding to a novel pocket on the CD4 receptor. We also identifi...

INTRODUCTION Many studies on the biological effects of electric and magnetic fields have been conducted since Wertheimer and Leeper reported an association between wiring configuration and childhood cancer among residents in Denver, Colorado. The genetic effects, especially mutagenicity and carcinogenicity, of electromagnetic fields have also been studied experimentally with positive and negati...

Introduction Due to their bioactive compounds and beneficial health effects, functional foods plant-based natural medicines are widely consumed. its bioactivities, vinegar is one of them that helps humans. Sugarcane original (SOV) a special made from sugarcane as raw material through biological fermentation processes. Methods The objective this study was assess the effects on growth performance...

A version of Modified Bacterial Foraging Optimization Algorithm to solve Constraints Numerical Optimization is tested. The proposal uses mutation operator, skew mechanism and local search operator. To prove the effectiveness of the mechanism and adaptations proposed, 24 well-known test problems are solved along set experiments. Performance measures are used for validating results obtained by th...
