Physiological and Perceived Effects of Forearm or Head Cooling During Simulated Firefighting Activity and Rehabilitation.

Context:  Cooling devices aim to protect firefighters by attenuating a rise in body temperature. Devices for head cooling (HC) while firefighting and forearm cooling (FC) during rehabilitation (RHB) intervals are commonly marketed, but research regarding their efficacy is limited.

Objective:  To investigate the physiological and perceived effects of HC and FC during firefighting drills and RHB.

Electrocardiographic abnormalities as potential contributors to premature mortality in patients with mental illness in a psychiatric day treatment program.

Objective: Because patients with mental illness can die prematurely, we sought to determine if undetected cardiovascular disease might be present in a psychiatric day treatment population.

Method: We studied 96 patients in a day treatment program seen between February 2011 and August 2012. Data were obtained through an electronic medical record database.

The acid-activated ion channel ASIC contributes to synaptic plasticity, learning, and memory.

Many central neurons possess large acid-activated currents, yet their molecular identity is unknown. We found that eliminating the acid sensing ion channel (ASIC) abolished H(+)-gated currents in hippocampal neurons. Neuronal H(+)-gated currents and transient acidification are proposed to play a role in synaptic transmission.
