Milk supply chain as a reservoir of antimicrobial-resistant species.

Milk is a source of essential nutrients, but food safety across the milk supply chain has emerged as an integral part of food trade. Of the several food safety hazards, antimicrobial-resistant species have emerged as one of the major microbial hazards with significant public health concerns. The present crosssectional study was undertaken with the objective to isolate species from the milk supply chain, characterize isolates for antimicrobial resistance, and trace the origin of isolates using molecular techniques.

Effect of Telmisartan on Arsenic-Induced (Sub-chronic) Perturbations in Redox Homeostasis, Pro-inflammatory Cascade and Aortic Dysfunction in Wistar Rats.

An experimental study was conducted in male Wistar rats to explore the antioxidant potential of telmisartan (an AT receptor blocker) to overcome arsenic ('As')-induced perturbations in redox homeostasis pro-inflammatory cytokines, prostaglandin-E levels and aortic dysfunction in Wistar rats. Wistar rats were randomly divided into four groups of six each. Group-I served as untreated control, while group-II received sodium (meta) arsenite (NaAsO) (10 mg/kg b.

Melatonin Ameliorates Neuropharmacological and Neurobiochemical Alterations Induced by Subchronic Exposure to Arsenic in Wistar Rats.

An experimental study was conducted in Wistar rats to characterize the arsenic ("As")-induced alterations in neurobiochemistry in brain and its impact on neuropharmacological activities with or without the melatonin (MLT) as an antioxidant given exogenously. Male Wistar rats were randomly divided in to four groups of six each. Group I served as untreated control, while group II received As [sodium (meta) arsenite; NaAsO] at 10 mg/kg bw (p.

Subchronic Arsenic Exposure Through Drinking Water Alters Lipid Profile and Electrolyte Status in Rats.

Arsenic is a groundwater pollutant and can cause various cardiovascular disorders in the exposed population. The aim of the present study was to assess whether subchronic arsenic exposure through drinking water can induce vascular dysfunction associated with alteration in plasma electrolytes and lipid profile. Rats were exposed to arsenic as 25, 50, and 100 ppm of sodium arsenite through drinking water for 90 consecutive days.

Arsenic causes aortic dysfunction and systemic hypertension in rats: Augmentation of angiotensin II signaling.

The groundwater pollutant arsenic can cause various cardiovascular disorders. Angiotensin II, a potent vasoconstrictor, plays an important role in vascular dysfunction by promoting changes in endothelial function, vascular reactivity, tissue remodeling and oxidative stress. We investigated whether modulation of angiotensin II signaling and redox homeostasis could be a mechanism contributing to arsenic-induced vascular disorder.

Atorvastatin ameliorates arsenic-induced hypertension and enhancement of vascular redox signaling in rats.

Chronic arsenic exposure has been linked to elevated blood pressure and cardiovascular diseases, while statins reduce the incidence of cardiovascular disease predominantly by their low density lipoprotein-lowering effect. Besides, statins have other beneficial effects, including antioxidant and anti-inflammatory activities. We evaluated whether atorvastatin, a widely used statin, can ameliorate arsenic-induced increase in blood pressure and alteration in lipid profile and also whether the amelioration could relate to altered NO and ROS signaling.

Subchronic arsenic exposure through drinking water alters vascular redox homeostasis and affects physical health in rats.

We evaluated whether arsenic can alter vascular redox homeostasis and modulate antioxidant status, taking rat thoracic aorta as a model vascular tissue. In addition, we evaluated whether the altered vascular biochemical homeostasis could be associated with alterations in the physical indicators of toxicity development. Rats were exposed to arsenic as 25, 50, and 100 ppm of sodium arsenite through drinking water for 90 consecutive days.
