Using an Adapted Job Demands–Resources Model to Examine the Use of Legal, Prescription, and Illegal Drugs for Cognitive Enhancement in the Working Population in Germany

open access: yesSociological Inquiry, EarlyView.
Chronic stress is a global issue with detrimental effects on health and productivity, often leading individuals to adopt health‐related coping strategies. This study uses an adapted Job Demands–Resources model to examine how various job demands and resources impact perceived stress and, consequently, the use of legal, prescription, and illegal drugs ...

Exercise during 14 days of head down tilt bedrest attenuates motor unit impairments in older humans

open access: yesExperimental Physiology, EarlyView.
Abstract Head‐down tilt bedrest (HDBR) models the effects of mechanical unloading on neuromuscular function. The efficacy of exercise in preserving motor unit (MU) function in older adults during HDBR remains unclear. This study investigated the effects of 14‐day HDBR on MU properties in older adults and the protective role of exercise.

Identification of TREK channels in mouse intracardiac ganglion neurons

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Role of TWIK‐related K+ (TREK) channels in intracardiac ganglion neurons. CD‐1 mice were used to establish primary cultures of intracardiac neurons for immunochemical characterization and patch‐clamp electrophysiology. Intracardiac neurons express functional TREK channels, which modulate neuronal excitability by regulating ...
