Chinese hamster ovary cells were exposed to the sulfhydryl compound cysteamine at concentrations ranging from 0 to 8 mM for 120 min. No toxicity was found in cells maintained at 5 degrees during treatment; however, at 37 degrees and 44 degrees a paradoxical toxicity was observed, i.e., substantial toxicity was observed at cysteamine concentrations of 0.2 to 1 mM but decreased at higher drug con...

The aim of our work was to compare cytotoxic and membrane-damaging effects of O. majorana L. essential oil and linalool on Hep G2 and to investigate their possible protective (antioxidant) effects against H2O2 induced membrane damage. The oils were investigated by GC and GC-MS and antioxidant activity was evaluated by DPPH and -carotene–linoleic acid assays. Assessment of cell viability was ma...

The present investigation was an attempt to elucidate oxidative stress induced by bisphenol A on erythrocytes and its amelioration by green tea extract. For this, venous blood samples from healthy human adults were collected in EDTA vials and used for preparation of erythrocytes suspension. When erythrocyte suspensions were treated with different concentrations of BPA/H2O2, a dose-dependent inc...

We determine paleoelevation of the Sierra Nevada, California, by tracking the effect of topography on precipitation, as recorded in hydrogen isotopes of kaolinite exposed in gold-bearing river deposits from the Eocene Yuba River. The data, compared with the modern isotopic composition of precipitation, show that about 40 to 50 million years ago the Sierra Nevada stood tall (>/=2200 meters), a r...

In this paper, we perform multi-sensor multi-resolution data fusion of Landsat-5 TM bands (at 30 m spatial resolution) and multispectral bands of World View-2 (WV-2 at 2 m spatial resolution) through linear spectral unmixing model. The advantages of fusing Landsat and WV-2 data are two fold: first, spatial resolution of the Landsat bands increases to WV-2 resolution. Second, integration of data...

this study presents a review on advanced oxidation processes (aop) for simultaneous removal of no and so2. aop is based on using a strong oxidant such as ozone and h2o2 which is able to generate highly reactive intermediates. the pollutant will be oxidized and removed by these intermediates. in recent years, aop has been considered as an effective and attractive technology in the field of flue ...

Oxidative damage plays a critical role in the etiology of neurodegenerative disorders including Parkinson's disease (PD). In our study, an ancient Chinese kidney-tonifying formula, which consists of Cistanche, Epimedii, and Polygonatum cirrhifolium, was investigated to protect MES23.5 dopaminergic neurons against hydrogen peroxide- (H2O2-) induced oxidative damage. The damage effects of H2O2 on...

Galactosylated BSA (galBSA) and its conjugate to horseradish peroxidase (galBSA-HRP) enter the galactose-specific pathway of hepatocytes. 10 min after intravenous injection, structures containing either ligand sediment mostly between 33,000 and 3 X 10(6) g X min (LP fraction) and have an equilibrium density of 1.11-1.13 g/ml in sucrose gradients (Quintart, J., P. J. Courtoy, J. N. Limet, and P....

This work presents the comparison of four advanced oxidation processes driven by UVC-LED radiation (278 nm—2 W/m2) for simultaneous bacteria inactivation (Escherichia coli—106 CFU/mL) and microcontaminant removal (imidacloprid—50 µg/L) in simulated wastewater secondary effluent. To this end, activation H2O2 S2O82− as precursors HO• SO4•−, respectively, UVC-LED/Fe3+–NTA (ferric nitrilotriacetate...
