ReviewVitamin E and D regulation of allergic asthma immunopathogenesis.
Asthma occurs as complex interactions of the environmental and genetics. Clinical studies and animal models of asthma indicate dietary factors such as vitamin E and vitamin D as protective for asthma risk. In this review, we discuss opposing regulatory functions of tocopherol isoforms of vitamin E and regulatory functions of vitamin D in asthma and how the variation in global prevalence of asthma may be explained, at least in part, by these dietary components.

High mobility group box 1 (HMGB1) has been identified to be a critical mediator of severe sepsis. Ketamine has been shown to reduce sepsis-induced pathological complications. These effects are because of the reduced expression and release of several inflammatory mediators. ⋯ Rats treated with ketamine improved survival in rats and significantly reduced CLP-induced dysfunction/injury of organs. Ketamine suppresses LPS-induced HMGB1 release in LPS-activated RAW264.7 cells and a CLP-induced model of sepsis in rats by partially inhibiting NF-κB/p38 MAPK pathways. Ketamine increased survival time induced by CLP and reduced organ dysfunction in septic peritonitis.
