A new family of outwardly rectifying potassium channel proteins with two pore domains in tandem. [PDF]

open access: yes, 1995
Potassium channels catalyse the permeation of K+ ions across cellular membranes and are identified by a common structural motif, a highly conserved signature sequence of eight amino acids in the P domain of each channel's pore-forming alpha-subunit. Here

Advanced Materials for Biological Field‐Effect Transistors (Bio‐FETs) in Precision Healthcare and Biosensing

open access: yesAdvanced Healthcare Materials, EarlyView.
This review explores how advanced materials enhance Bio‐FETs for precision healthcare and biosensing. It covers their working principles, surface functionalization, and ultra‐sensitive detection capabilities. The integration of flexible designs, AI, and IoT for real‐time monitoring is discussed, along with challenges like material reproducibility and ...

Potassium Channels in the Human Myometrium

open access: yesExperimental Physiology, 2001
The contractility of the human uterus is under the fine control of a variety of interacting bioactive agents. During labour, the excitability of the uterus is drastically transformed in comparison with the non‐labour state and is manifest at the membrane level via the acivity of uterine ion channels.

Designing for Degradation: Transient Devices Enabled by (Nano)Cellulose

open access: yesAdvanced Materials, EarlyView.
Recent progress in transient devices enabled by (nano)cellulosic materials is reviewed. Transiency mechanisms, advantages of nanocelluloses, and a suite of applications are discussed. A circular thinking approach coupled with life cycle assessment is applied to critically revisit the potential, advantages, and challenges of nanocellulose‐enabled ...

Calcium and Potassium Channels in Experimental Subarachnoid Hemorrhage and Transient Global Ischemia

open access: yesStroke Research and Treatment, 2012
Healthy cerebrovascular myocytes express members of several different ion channel families which regulate resting membrane potential, vascular diameter, and vascular tone and are involved in cerebral autoregulation.

A Surprising Clarification of the Mechanism of Ion-channel Voltage-Gating [PDF]

open access: yesarXiv, 2006
An intense controversy has surrounded the mechanism of voltage-gating in ion channels. We interpreted the two leading models of voltage-gating with respect to the thermodynamic energetics of membrane insertion of the voltage-sensing 'module' from a comprehensive set of potassium channels.

The scorpion toxin and the potassium channel

open access: yeseLife, 2013
The structure of a complex containing a toxin bound to a potassium ion channel has been solved for the first time, revealing how scorpions have designed toxins that can recognize and target the filter that controls the movement of potassium ions through these channels.

KCNKØ: opening and closing the 2-P-domain potassium leak channel entails "C-type" gating of the outer pore. [PDF]

open access: yes, 2001
Essential to nerve and muscle function, little is known about how potassium leak channels operate. KCNKØ opens and closes in a kinase-dependent fashion. Here, the transition is shown to correspond to changes in the outer aspect of the ion conduction pore.

Rapid Surface Reconstruction of In2S3 Photoanode via Flame Treatment for Enhanced Photoelectrochemical Performance

open access: yesAdvanced Materials, EarlyView.
A rapid surface reconstruction strategy is proposed to enhance the charge collection efficiency and stability of indium sulfide (In2S3) photoanode via a high‐temperature flame treatment. This method selectively transforms the In2S3 surface into a diffusionless In2O3 and generates bulk sulfur vacancies, resulting in surface‐reconstructed In2S3 (sr‐In2S3)
