purpose: to investigate the penetration of cefixime, cephalexin and ciprofloxacin into the human eye based on microbial inhibition by human aqueous samples after oral administration. method: sixty patients aged 40 to 75 years who were scheduled for cataract surgery were divided into three equal groups. one group received 500 mg oral ciprofloxacin 24, 12 and 2 hours preoperatively; another group...

background and aims: influenza a virus infects birds and some mammalian including human. h1 and h3 subtypes are circulated in both human and birds’ population. to determine the prevalence of the mentioned subtypes in birds, different captive bird species in tehran zoo, and affiliated centers in tehran were investigated for virus infection. methods: in this study, between november 2008 and febru...

microtubule affinity-regulating kinase 2 (mark2) protein has a substantial role in regulation of vital cellular processes like induction of polarity, regulation of cell junctions, cytoskeleton structure and cell differentiation. the abnormal function of this protein has been associated with a number of pathological conditions like alzheimer disease, autism, several carcinomas and development of...

this work studies the biosurfactants production which enables the diesel biodegradation byusing mixed microbial consortia from polluted sites. it was carried out by culturing three microbial consortia(named as xa, xb and xc) obtained from polluted soils, and enriched in diesel as sole carbon source.batchexperiments were done to study the effects of three variables (temperature,hydrocarbon conce...

neurodegeneration is the pathophysiological basis for permanent neurological disabilities in multiple sclerosis (ms); thus neuroprotection is emerging as a therapeutic approach in ms research. modulation of excitotoxicity by inhibition of nmdars has been suggested for neuroprotection, but selective antagonisation of the nr2b subtype of these receptors, a subtype believed to play a more pivotal ...

Inhibition performances of imidazoline derivatives with different alkyl chain length for carbon steel in H2S acid solutions has been studied by polarization curves, AC impedance measurements, current transient, Atomic Force Microscopy (AFM) and Density Functional Theory (DFT) techniques. Results showed that the inhibition occurs through adsorption of the inhibitors molecules ...

Effects of different carbon sources on growth and production of antifungal agent(s) by Gymnopilus spectabilis were investigated. Different carbon sources including; Glucose, fructose, lactose, maltose, manitol and sucrose at the concentration of 10 g/l and slow releasing carbon sources including malt extract and soluble starch at the concentration of 2g/l were used. Inhibition of spore germinat...

The corrosion behavior of mild steel (Ck 45) in 3.0 M H3PO4 solution in the absence and presence of penicillin G was studied using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques. The best inhibition effect at 10 mM of drug was a marked characteristic of the inhibitor. It was found that the inhibition efficiency of the inhibitor...

The cytotoxic activity of ethanolic extracts of Thymus vulgaris, Thuja orientalis and Achillea millefolium was investigated on various growing tumor cell lines. MTT colorimetric assay was used for measuring the inhibition of cell proliferation. All of the three extracts showed a relatively dose-dependent inhibition of proliferation of human breast cancer (SK-Br-3, MDA-MB-435) and leukemia ...
