Polymerizable sol-gel synthesis of dark-visible light antibacterial magnetically-recoverable AgBr-loaded iron oxide/alumina nanocomposite.

The demand for a facile approach for synthesizing multifunctional nanocomposites is increasingly vital across diverse applications. In this study, a polymerizable sol-gel synthesis has been reported to obtain nanocomposites of magnetic iron oxide deposited over alumina nanopowder. The synthesis is mediated by the deposition of a calculated amount of iron(III) methacrylate, along with ethylene glycol dimethacrylate crosslinker, over alumina nanopowder, followed by thermally-inducing free radical polymerization at 125 °C for 30 min.

Association between duration of coal dust exposure and respiratory impairment in coal miners of West Bengal, India.

. The prevalence and severity of respiratory disorders are very high among coal miners as continuous exposure of workers in such an environment leads to accumulation of dust in the lungs. This study was designed to assess the prevalence of lung function impairment and to determine whether there is any correlation between dust exposure duration and lung function indices.

Radioprotective effect of ethanolic extract of on γ-irradiation-induced reproductive alterations in ovary and uterus.

Evaluation of the modulatory effect of ethanolic extract of tuber (EEAIT) against γ-irradiation induced ovarian and uterine toxicity. Extract preparation was done by 80% hydro-ethanol using Soxhlet apparatus. EEAIT was administered to female Swiss albino mice ( 5) daily (200 and 400 mg/kg body weight/d) for 7 days before γ-irradiation exposure (2.

Combined effect of coal dust exposure and smoking on the prevalence of respiratory impairment among coal miners of West Bengal, India.

Accelerating prevalence of coal workers pneumoconiosis is considered as a serious occupational health problem. This cross-sectional study was designed to determine the prevalence of lung function impairment of underground coal miners in West Bengal, India. A total of 230 underground coal dust-exposed subjects and 130 nonexposed subjects were examined for lung function test and also information on sociodemographic characteristics, addiction, respiratory morbidity, personnel protective equipment and dust exposure were collected.

Targeting mitochondria with folic acid and vitamin B ameliorates nicotine mediated islet cell dysfunction.

Nicotine, one of the well-known highly toxic components of cigarette smoke, causes a number of adverse health effects and diseases. Our previous study has shown that nicotine induces reactive oxygen species (ROS) in islet cell and disrupts islet cell mitochondrial membrane potential (ΔΨm). However, supplementation with folic acid and vitamin B were found effective against nicotine induced changes in pancreatic islet cells.

Possible involvement of iNOS and TNF-α in nutritional intervention against nicotine-induced pancreatic islet cell damage.

Nicotine is the more abundant and most significant components of cigarette smoke. Epidemiological evidence strongly suggests an association between cigarette smoking and pancreatic injury. Although effects of smoking on endocrine pancreas are still controversial Here, we examined the impact and underlying mechanisms of action of folic acid and vitamin B12 on nicotine induced damage in pancreatic islets of rats.
