background : lack of physical activity is the fourth common cause of human death. given the increased rate of sedentary life style among employees, the aim of this study was to evaluate physical activity status of governmental employees in changing stage based on the transtheoretical model (ttm) in hamadan, iran, in 2014. methods: this descriptive-analytical study was performed on 1200 governme...

objectives the aim of this study was to identify the relation between physical activity level and the structures of trans-theoretical model (ttm). materials and methods this cross-sectional study was conducted on 423 female students of tonekabon in iran. participants completed the demographic questionnaires, the ttm’s structural questionnaires as well as the international physical activity ques...

microbial phytases were applied mainly to animal and human foodstuffs in order to improvemineral bioavailability and food processing. in addition, phytases have potentialbiotechnological application in various other fields, such as environmental protection,aquaculture and agriculture. bacillus sp. dm12, an isolate from a hot spring, produces phytase,which catalyzes the hydrolysis of phytic acid...

background drug resistance of microorganisms to antimicrobial agents is on the rise. therefore, an alternative route to overcome drug resistance of various microorganisms is needed. objectives this study was conducted to assess antibacterial activity of silver nanoparticles (agnps) produced by satureja hortensis extract against bacillus cereus isolated from soil of sistan plain (zabol, southeas...

the resistance of antimicrobials has become a global hazard with the irrational use of antibiotics. infection of drug-resistance bacteria seriously threatens human health. currently there is an urgent need for the development of novel antimicrobial agents with new mechanisms and lower levels of toxicity. in this paper, a series of (s,z)-4-methyl-2-(4-oxo-5-((5-substitutedphenylfuran-2-yl) methy...

there has been special interest in the chemistry of quinolone and pyrimidine derivatives due to their diverse biological activities such as anticonvulsant, anti-malarial agents, antibacterial, antiviral, cytostatic, antithelemintic, antigenotoxic, anti-cancer agents. these compounds are also used as targeting delayed-type hypersensivity and anti-convulsant agents. as a part of our research work...

antibacterial activity of the aerial extracts from xanthium brasilicum prepared in methanol, diethyl ether, petroleum benzene and an equal mixture of the three solvents were studied against bacterial laboratory standards and clinical isolates using the disk diffusion method. the best antibacterial results were obtained when methanol or the solvent mixture was used. the crude extract with the hi...
