Elucidating the physiological mechanisms underlying enhanced arsenic hyperaccumulation by glutathione modified superparamagnetic iron oxide nanoparticles in Isatis cappadocica.

Widespread arsenic (As) contamination is a severe environmental and public health concern. Isatis cappadocica, an arsenic hyperaccumulator, holds great potential to clean up As-contaminated soil and groundwater. Iron oxide is one of the most common metal oxides in the natural environment and its nanoparticulate form has been previously utilized for the removal of heavy metals/metalloids from wastewater.

Protective effect of vitamin E against diabetes-induced oxidized LDL and aorta cell wall proliferation in rat.

Unlabelled: Hyperlipidemia and oxidized-low-density lipoproteins (Ox-LDL) are important independent cardiovascular risk factors that have been shown to stimulate vascular smooth muscle cell (VSMC) proliferation. The purpose of the present study was to investigate the effect of vitamin E on Ox-LDL, lipid profile, C-reactive protein (CRP), and VSMC proliferation of rat aorta.

Methods: Male Wistar rats (n = 32) were divided into four groups namely: sham (SH), control (C), non-treated diabetic, and vitamin E-treated diabetic (VETD) groups.

Kinetic study on the Cs(x)H(₃-x)PW₁₂O₄₀/Fe-SiO₂ nanocatalyst for biodiesel production.

The kinetic of the transesterification reaction over the Cs(x)H(₃-x)PW₁₂O₄₀/Fe-SiO₂ catalyst prepared using sol-gel and impregnation procedures was investigated in different operational conditions. Experimental conditions were varied as follows: reaction temperature 323-333 K, methanol/oil molar ratio = 12/1, and the reaction time 0-240 min. The H₃PW₁₂O₄₀ heteropolyacid has recently attracted significant attention due to its potential for application in the production of biodiesel, in either homogeneous or heterogeneous catalytic conditions.

Vasoprotective effect of vitamin E: rescue of ethanol-induced atherosclerosis and inflammatory stress in rat vascular wall.

Chronic ethanol consumption increases the incidence of cardiovascular disease. The mechanisms underlying ethanol-induced susceptibility to cardiovascular disease continue to be defined. This study examines the hypothesis that chronic ethanol consumption plausibly induces vascular wall abnormalities via inflammatory reactions.

Effects of vitamin E on pathological changes induced by diabetes in rat lungs.

Twenty-fourmale rats were divided into three groups: Control (C), non-treated diabetic (NTD), and vitamin E-treated diabetic (VETD) groups. After 6 weeks, we evaluated the changes in the alveolar epithelium, alveolar septum thickness, Hcy, and cathepsin G levels in the lung tissue and plasma serine protease inhibitor levels.The results revealed a significant increase in alveolar septum thickness, a high number of type II pneumocytes, high number of glycogen granules, increased vascular elastic membrane thickness, and increased Hcy and cathepsin G levels in the diabetic rats.
