Objective(s): In this work, pomegranate juice was used as a capping agent for self- assembly to form particles-like Au nanostructures in the presence of AuHCl4.3H2O as aurate source. Besides, to investigate the concentration effect of pomegranate juice as the green capping agent on the morphology and particle size of final products several experiments were...

71 samples of milk and dairy products were collected from 18 cities throughout iran. 93 strains of lactic acid bacteria (lab) were isolated and assayed against four opportunistic patho gens including e. coli, proteus and klebsiella as gram-negative and s. aureus as a gram-positive organism. all indicators (organisms) were hospital strains. among isolated bacteria, lactobacilli (37 isolates) had...

sudarshan churna (sc) is very potent ayurvedic medicine ; composed of 42 medicinal plants, which is used traditionally in treatment of malaria, viral fever, and bacterial infection. the present study was designated to evaluate the antimicrobial activity of aqueous extract of sudarshan churna (asc) using the paper disc diffusion method. the asc was found active against the gram-negative bacteria...

aims: the internal unit and icu of hospitals are a suitable environment for growing of bacteria such as staphylococcus epidermidis and pseudomonas, acinetobacter. the aim of our study was to evaluate the effect of different disinfectants on bacteria isolated from the surface of hospitals in isfahan. instrument & methods: in this study, 200 samples were randomly selected from different parts of ...

abstract background: streptococcus mutans in the oral cavities sable to produce mutacin (bacteriocin-like substances) with antibiotic properties. the aim of this study was to investigate the frequency and expression of genes encoding mutacins typei, ii, iii and iv and also two of 8 genes in a cluster encoding the putative bacteriocins, the designated bsm 283, bsm 299, bsm 423, bsm 1889c, bsm 18...

quinolones are broad-spectrum antibacterial agents.they have many clinical uses which are increasing.quinolones exert antibacterial activity primarily by inhibiting bacterial DNA gyrase.the inhibition of DNA gyrase by the quinolones are greatly influenced by the nature of the C-7 substituent on the quinolones molecule.substitution of bulky functional groupd is also possible in C-7 position.furt...
