in vitro antifungal activity of silver nanoparticles, at concentrations of 6, 8, 10, 12, 14 and 16 ppm, was studied on five phytopathogenic fungi, and a biocontrol agent. then effect of silver nanoparticle at 6 ppm (optimum concentration) was evaluated on macrophomina phaseolina in greenhouse. for in vitro experiment, the fungal isolates were grown on potato dextrose agar medium amended with si...

The Inhibition efficiency of Rosemary oil (Rosmarinus officinalis) for corrosion control high carbon steel was done in citric acid medium by weight loss method. Rosmarinus officinalis administered the proportion 0%, 0.50%, 1.00%, 1.50%, 2.00% and 2.50% concentration. This study unveiled that inhibition performed excellently with maximum percentage 88.3% at room temperature 0.5M solution. has sh...

the present investigation was carried out to isolate and characterize antagonistic bacteria against wilt causing fungal pathogen i.e. fusarium oxysporum, from the rhizosphere of tomato. fifty-six bacterial strains were isolated from the rhizosphere soil samples of healthy tomato fields, collected from different locations of faridabad district, haryana, india. out of these, ten isolates were fou...

one hundred sera from children 1 - 6 years of age, representative of a large serum collection, were tested for the prevalence of antibodies against different viruses. hemagglutination-inhibition (hi) antibodies were found in 68% for measles; 61 % for rubella; 75'% for influenza a2/hong kong/68, 16% for influenza b/md./59, 0% for group a arboviruses, 10% for group b arboviruses, 3% for phlebotom...

introduction and aims: omeprazole is a gastric parietal cells proton pump inhibitor that is also active against h. pylori in vitro. this study was designed to examine the neutralization of h. pylori cytotoxicity on vero cells by omeprazole micronized in strains isolated from gastritis, ulcer, cancer and barrett's ulcer, to determine whether omeprazole can inhibit vacuolation of the vero cells i...

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...

Abstract Introduction Withholding uninitiated actions and cancelling ongoing ones are two main components of response inhibition, a key element the executive control. Inhibitory performance is sensitive to emotional contexts elicited by subliminal supraliminal visual material. However, whether stimuli from other sensory modalities, such as odours, would equally modulate inhibition remains uncle...

The purpose of this project was to evaluate the antibacterial potential phytochemicals rutin, syringic acid, and Ziziphus mucronata extract on Chromobacterium violaceum quorum sensing. Z. extracts were imported from South Africa, then extracted in lab; a SEM imaging series conducted for contamination further develop portfolio it. null hypothesis if plant compounds are tested individually, they ...
