chromium (cr) is one of the elements presents in crust of the earth. due to its toxicity, chromium is considered as water contaminant that may disturb metabolic activity. in the present study, adsorption of dissolved chromium (vi) onto elaeagnus angustifolia fruit charcoal, jujube fruit charcoal and the standard granular activated carbon (gac) has been investigated and compared. the effect of c...

phosphorus (p) is one a nutrient elements for plant growth. in most soils has complex behavior and forms sparingly soluble compounds with soil particles. phosphorus bioavailability can be controlled by soil biological activities for optimum nutrition of plants. this study was carried out in order to isolation of p-solubilizing bacteria (psb) as well as p-solubilizing fungi (psf) and their scree...

the complexation reactions of some transition metal ions and 2-aminopyridine (2-ampy) were studied potentiometrically in aqueous solution at µ=0.1 m and 25 °c. the overall stability constants log β’s of all species are obtained by computer refinement of ph-volume data with using the best computer program. several models were tested and the best one accepted according to the least sum of squared...

background: epigallocatechin gallate (egcg), a major constituent of green tea, has been introduced as a potent free radical scavenger and can effectively reduce free radical-induced lipid peroxidation. since free radical injury plays an important role in neuronal damage in parkinson’s disease (pd), this study examined whether egcg administration would reduce functional asymmetry in an experimen...

conclusions these results suggest that toxins induce inflammatory responses, particularly through expression of chemokine. recombinant stx and native toxin induced apoptosis by balancing between different pro- and anti-apoptotic bcl-2 family-factors in epithelial cells. in this study, for the first time, recombinant and native stx induction of apoptotic factors and stimulation of immune respons...

background: glioblastoma is the most common and most malignant cancer of central nervous system. targeted radiotherapy is an effective method toward its treatment. iododeoxyuridine (iudr) is a halogenated thymidine analogue known to be effective as a radiosensitizer in human cancer therapy. in this study we have evaluated the combination effects of 2-methoxyestradiol, an inhibitor of hypoxia in...

the chemical composition of the essential oil of fruits of pimpinella haussknechtiiboiss.was studied by gc-ms. after gc-ms analysis, one unknown component (56.7%) was observed, which was not characterized in the gc-ms library. the essential oil of p.hauskenekhtii was injected to hplc using ymc-pak-sil column (250 × 20 mm) with gradient system of hexane (a), and hexane: ethyl acetate, 9:1 (b) to...

to review the diffrent aspects of gender, subtype of cah, management and results in all our patients with ambiguous genitalia diagnosed as congenital adrenal hyperplasia during the past 30 years. methods: the files of all our patients with cah reviewed retrospectively. results: out of 256 patients who had ambiguous genitalia due to cah, 96% were female and 4% were male. 21-ohd was diagnosed in ...

objective(s): lipocalin2 (lcn2) gene is highly expressed in response to various types of cellular stresses. the precise role of lcn2 has not been fully understood yet. however, it plays a key role in controlling vital cellular processes such as proliferation, apoptosis and metabolism. recently it was shown that lcn2 decreases senescence and increases proliferation of mesenchymal stem cells (msc...
