Epidemiology of yoga-related injuries in Canada from 1991 to 2010: a case series study.

The aim is to describe the epidemiology of yoga injuries presenting to select Canadian emergency departments (EDs). Those who presented with a yoga injury to a Canadian ED participating in the Canadian Hospitals Injury Reporting and Prevention Program and had completed a data collection form between 1991 and 2010 were included. Demographic and injury characteristics were tabulated and injury profiles of children were compared to adults.

Listening to a personal music player is associated with fewer but more serious injuries among snowboarders in a terrain park: a case-control study.

Background: Some snowboarders listen to music on a personal music player and the objective was to determine if listening to music was associated with injury in a terrain park.

Methods: A case-control study was conducted at a terrain park in Alberta, Canada during the 2008-2009 and 2009-2010 winter seasons. Cases were snowboarders who were injured in the terrain park and presented to either the ski patrol and/or a nearby emergency department (ED).

MicroRNA 146a (miR-146a) is over-expressed during prion disease and modulates the innate immune response and the microglial activation state.

Increasing evidence supports the involvement of microRNAs (miRNAs) in inflammatory and immune processes in prion neuropathogenesis. MiRNAs are small, non-coding RNA molecules which are emerging as key regulators of numerous cellular processes. We established miR-146a over-expression in prion-infected mouse brain tissues concurrent with the onset of prion deposition and appearance of activated microglia.
