Asafetida (Ferula assa- foetida L.) is an important medicinal plant belonging to Apiaceae family and has long dormancy. In this research, vernalization, washing time, GA3, medium strength, harvesting time and interaction of these treatments were studied to optimize condition of germination. The results showed that vernalization at 4-5°C for two weeks increased germination by 50%, as compare...
identification and transfer of desirable genes from wild relatives to crop species is one of the breeding solutions for producing resistance to pathogens and pests. this study was conducted to evaluate crossability and the response to pythium ultimum in three species of the genus carthamus. to assess response to the pathogen, eight safflower (carthamus tinctorius l) genotypes, two ecotypes of c...
Identification of Candida cultured from various clinical specimens to the species level is increasingly necessary for clinical laboratories. Although sn PCR identifies the species within hours but its cost-effectiveness is to be considered. So there is always a need for media which help in the isolation and identification at the species level. The study aimed to evaluate the performance of diff...
High-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) are strong predictors of atherosclerosis. Statin-induced changes in the ratio of LDL-C to HDL-C (LDL-C/HDL-C) predicted atherosclerosis progression better than LDL-C or HDL-C alone. However, the best predictor of subclinical atherosclerosis remains unknown. Our objective was to investigate this issue by...
Human telomerase reverse transcriptase (hTERT) is upregulated in most cancer cell types as well in immortalized cells. The underlying mechanism for such upregulation, however, remains largely unknown. We report here that bile acids under acidified media increase hTERT expression via c-myc activation in primary human gastric cancer cell lines. Human gastric cancer MKN28, MGC803 and SGC7901 cells...
As there are sparse data on the impact of growth media on the phenomenon of biofilm development for Candida we evaluated the efficacy of three culture media on growth, adhesion and biofilm formation of two pathogenic yeasts, Candida albicans and Candida tropicalis. The planktonic phase yeast growth, either as monocultures or mixed cultures, in sabouraud dextrose broth (SDB), yeast nitrogen base...
The origin of desacetylcephalosporin C in cephalosporin C fermentation broths was investigated. Esterase activity was detected in cell-free extracts of Cephalosporium acremonium, but these extracts failed to deesterify cephalosporin C. When cephalosporin C was added to sterile and inoculated fermentation media, the antibiotic decayed at nearly identical rates. The formation of desacetylcephalos...
ABSTRACT- The aim of this study was to investigate the effects of “Arbuscular mycorrhizal fungi” (AM fungi) density and different growing media on the growth, photosynthesis parameters and yield of sweet pepper under greenhouse conditions. The experiment was conducted as a factorial plan based on control randomized design (CR...
Several concentrations of 9-chloro-9-(4-diethylaminophenyl)-10-phenylacridan (C-390), ranging from 5 to 100 micrograms/ml, were incorporated in brain heart infusion agar, MacConkey agar, and xylose-lysine-deoxycholate agar to evaluate the recovery of Pseudomonas aeruginosa from 538 sputum, 174 urine, and 22 stool samples. Seventy-six sputum samples containing P. aeruginosa grew this bacterium a...
