background and objectives: bacterial resistance to antibiotics has motivated the researchers to evaluate the novel anti-bac- terial compounds such as some thiazole and imidazole derivatives. thereby, in this work, we investigated the anti-bacterial effects of one new thiazole and two new imidazole derivatives on bacillus cereus , listeria monocytogenes , escherichia coli, salmonella typhimurium...

exploration of natural products with antitumoral effects such as etoposide, tenioposide, camptothecin and paclitaxel from conifers provoked us to do some research on anti-tumoral activity of iranian medicinal plants. ten different species of iranian conifers aerial parts were collected across the country. the relative potency of methanolic extract were investigated on the inhibition of topoisom...

background and objective: antibiotic consumption is the main way to cure infection induced by helicobacter pylori. on the other hand, antibiotics have side effects on human body. so, finding an efficient way to replace antibiotic consumption seems necessary. the aim of this study was to investigate the effect of broccoli sprout extract on the viability of probiotic bacteria and yogurt’s physico...

Background and Aim: This study aimed to compare the effects of acetone and ethanolic extracts of Plantago major (P. major) on S. mutans.   Materials and Methods: In this in vitro study, the antibacterial effects of eight different concentrations of the acetone and ethanolic extracts of P. major seed were examined on S. mutans, and the minimum inhibitory concentration (MIC) and minimum bacte...

effects of different carbon sources on growth and production of antifungal agent(s) by gymnopilus spectabilis were investigated. different carbon sources including; glucose, fructose, lactose, maltose, manitol and sucrose at the concentration of 10 g/l and slow releasing carbon sources including malt extract and soluble starch at the concentration of 2g/l were used. inhibition of spore germinat...

The present study was designed to examine the effects of Lactobacillus plantaraum and L. paracasei on the growth and aflatoxin-producing ability of Aspergillus parasiticus. In these experiments, direct and indirect interactions of two different probiotic lactobacilli with A. parasiticus was examined.A co-culture system which supported both fungal growth and probiotic bacteria showed the inhibit...

background: recently, the anti cancer effect of chromene derivatives in different cell types has been reported. in this study, we report some derivatives of dihydropyrano[c]chromenes with growth inhibitory and apoptotic activity against k562, chronic myeloid leukaemia (cml). methods: the cells were seeded in 96-well plates at 1×105 cells/well and treated with different concentrations of the dih...
