some plant extracts have been reported to exhibit antimicrobial properties. plant based pesticides appear to be an alternative for the synthetic pesticides because of their less dangerous impacts. the objective of this study was to assess the inhibitory activity of brassica napus water extract on mycelial growth of six phytopathogenic fungi rhizoctonia solani, phythophtora drechseleri, pythium ...

Many bacterial pathogens are becoming drug resistant faster than we can develop new antimicrobials. To address this threat in public health, a metamodel antimicrobial cocktail optimization (MACO) scheme is demonstrated for rapid screening of potent antibiotic cocktails using uropathogenic clinical isolates as model systems. With the MACO scheme, only 18 parallel trials were required to determin...

among 160 samples collected from rice paddy of the guilan province including rice plant, seed, rhizospher, paddy's soil, paddy's water and sclerotium of the causal agent of rice sheath blight (rhizoctonia solani), 610 bacterial strains were isolated. 71 bacterial strains (11.64%) had the ability of inhibition mycelial growth fungus in dual culture test on pda medium. according to two characteri...

Objective(s): Blocking of vascular endothelial growth factor (VEGF) plays a pivotal role in inhibition of metastasis and is a target for development of anti-angiogenic agents. In this study, a peptide-based vaccine was designed and its potential for induction of humoral immune responses, generation of neutralizing antibodies, inhibition of tumor growth and metastasis w...

ABSTRACT Stachys is one of the largest genera in the flowering plant family. It is in the subfamily Lamioideae (Labiatae), spreading and growing in different parts of Iran. The purpose of this study was to investigate the chemical properties of Stachyslavandulifolia as well as the essence, ethanol and methanol extracts of this plant. It was collected from Chulus located in the West of Mazandara...

in the present study the distribution of rubella hemagglutination inhibition (hi) antibody titer in the sera of 1486 women of 18 to 25 years old residing in tehran were examined. sera were pretreated with acid washed kaolin and pigeon red blood cell. titers below 1:10 and in some studies below 1:20 are considered nonimmune to rubella. our results show that 10, 29% of studied population had hi a...
