Selenium supplementation through Se-rich dietary matrices can upregulate the anti-inflammatory responses in lipopolysaccharide-stimulated murine macrophages.

The accessibility of selenium from naturally enriched sources such as cereals crops can potentially be used as selenium supplements to support nutritional requirements. Dietary selenium supplementation, as Se-rich wheat extracts, on RAW264.7 macrophage cells enhanced the antioxidant capacity via augmentation of cellular selenoprotein glutathione peroxidase 1 (GPx-1) expression in the absence or presence of lipopolysaccharide (LPS) treatment.

Persistence and biodegradation of quinalphos using soil microbes.

The present study reports the degradation of the persistent and toxic organophosphate, quinalphos, by employing microorganisms that were already members of the natural soil community for degradation. Bacillus and Pseudomonas spp., both of which are capable of degrading quinalphos from aqueous streams, were isolated from different contaminated soils.
