The saponin rich fraction (SRF) of Bacopa monnieri were prepared and evaluated for in vitro immune response using murine immune cells. Thioglycollate medium elicited peritoneal exudates cells (PEC) were used to study in vitro effects of the fraction (SRF) on release of immune mediators. SRF was evaluated at different concentrations (832 – 6.5μg/ml) for release of nitric oxide (NO), superoxide (...

The chemical composition of the essential oils from the fruits of Daucus carota var. sativus (yellow carrot) and var. boissieri (red carrot) was determined using GC/FID and GC/MS. Altogether; 29 and 32 compounds were identified accounting for 96.58 and 96.72 % of the total detected components in the hydrodistilled yellow and red carrot oils, respectively. Carotol constituted the major component...

Many studies have evidenced that the phenolic components from flaxseed (FS) oil have potential health benefits. The effect of the phenolic extract from FS oil has been evaluated on two human breast cancer cell lines, MCF7 and MDA-MB231, and on the human non-cancerous breast cell line, MCF10A, by SRB assay, cellular death, cell cycle, cell signaling, lipid peroxidation and expression of some key...

objective: grape virus diseases are a serious problem in iran. leaves and fruits of grape have been used for different purposes like cooking in iran. the present investigation was carried out to study on the cytotoxic-activities of extracts of fruits and leaves of vitis vinifera from both virus-free and virus-infected grape cultivars against breast cancer cell line (mda-mb-231) and human embryo...

background: achillea talagonica (asteraceae) is an endemic herbaceous plant in iran with small yellow flowers and several times pinnately divided leaves in worm shape. the plant was found to be cytotoxic in our previous studies.   materials and methods: a. talagonica was collected in may 2005 from talegan in north of iran during the full flowering stage. dried aerial parts of the plant were red...

Here we describe the diversity and activity of sulfate-reducing bacteria (SRB) in sulfidogenic bioreactors by using the simultaneous analysis of PCR products obtained from DNA and RNA of the 16S rRNA and dissimilatory sulfite reductase (dsrAB) genes. We subsequently analyzed the amplified gene fragments by using denaturing gradient gel electrophoresis (DGGE). We observed fewer bands in the RNA-...

The main intention of this study to understand the microbial consortium of Sulphate Reducing Bacteria(SRB) and Sulphure oxidizing bacteria (SOB) on Extra polymeric substance produced by Pseudomonas sp., with combination of E-coli. In stressing the importance of anaerobic corrosion by SRB, corrosive effects of acids produced by microorganisms may be overlooked Sulphur oxidizers chiefly of the ge...

Marine microorganisms are important sources for novel natural products. Hence, the aim of this study was introducing the marine microorganisms with capability to produce antioxidant and cytotoxic metabolites. For this purpose, ten live sea cucumbers (Holothuria leucospilota) were collected from Larak Island. Then, their intestine contents were serially diluted and treated by heating (55 °c). 10...
