[A Local Gender Equality Plan - A Modern Human Resources Development Tool].

The implementation of equal opportunities is a challenge for the staff of an anaesthesia department. At the Department of Anaesthesiology and Intensive Care Medicine at Hannover Medical School, a local Gender Equality plan has been implemented to create a secure and transparent framework for reconciling scientific and clinical careers with family responsibilities. Today, family and career should be equally compatible for men and women.

Functional and structural insights into activation of TRPV2 by weak acids.

Transient receptor potential (TRP) ion channels are involved in the surveillance or regulation of the acid-base balance. Here, we demonstrate that weak carbonic acids, including acetic acid, lactic acid, and CO activate and sensitize TRPV2 through a mechanism requiring permeation through the cell membrane. TRPV2 channels in cell-free inside-out patches maintain weak acid-sensitivity, but protons applied on either side of the membrane do not induce channel activation or sensitization.

The coumarin osthole is a non-electrophilic agonist of TRPA1.

The naturally occurring coumarin osthole has antipruritic properties, and recent reports suggest that this effect is due an inhibition or desensitization of the cation channels TRPV1 and TRPV3. Osthole was also suggested to activate TRPA1, an effect that should rather be pruritic than antipruritic. Here we characterized the effects of osthole on TRPA1 by means of ratiometric calcium imaging and patch clamp electrophysiology.

Gating of the capsaicin receptor TRPV1 by UVA-light and oxidants are mediated by distinct mechanisms.

Redox-sensitivity is a common property of several transient receptor potential (TRP) ion channels. Oxidants and UVA-light activate TRPV2 by oxidizing methionine pore residues which are conserved in the capsaicin-receptor TRPV1. However, the redox-sensitivity of TRPV1 is regarded to depend on intracellular cysteine residues.
