Vibrational Spectra of a Mechanosensitive Channel [PDF]

open access: yes, 2013
We report the simulated vibrational spectra of a mechanosensitive membrane channel in different gating states. Our results show that while linear absorption is insensitive to structural differences, linear dichroism and sum-frequency generation ...

VAMP721 conformations unmask an extended motif for K+ channel binding and gating control [PDF]

open access: yes, 2016
Soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) proteins play a major role in membrane fusion and contribute to cell expansion, signaling, and polar growth in plants.

Membrane mechanics as a probe of ion-channel gating mechanisms [PDF]

open access: yes, 2008
The details of conformational changes undergone by transmembrane ion channels in response to stimuli, such as electric fields and membrane tension, remain controversial.

Activity and Ca2+ regulate the mobility of TRPV1 channels in the plasma membrane of sensory neurons

open access: yeseLife, 2015
TRPV1 channels are gated by a variety of thermal, chemical, and mechanical stimuli. We used optical recording of Ca2+ influx through TRPV1 to measure activity and mobility of single TRPV1 molecules in isolated dorsal root ganglion neurons and cell lines.

Multi-Talker Speech Promotes Greater Knowledge-Based Spoken Mandarin Word Recognition in First and Second Language Listeners

open access: yesFrontiers in Psychology, 2020
Spoken word recognition involves a perceptual tradeoff between the reliance on the incoming acoustic signal and knowledge about likely sound categories and their co-occurrences as words.

Molecular Dynamics Simulations of a Cytochrome P450 from Tepidiphilus thermophilus (P450-TT) Reveal How Its Substrate-Binding Channel Opens

open access: yesMolecules, 2021
Cytochrome P450s (P450) are important enzymes in biology with useful biochemical reactions in, for instance, drug and xenobiotics metabolisms, biotechnology, and health.

Time-resolved optical gating based on dispersive propagation: a new method to characterize optical pulses [PDF]

open access: yes, 2000
We introduce the technique of time-resolved optical gating (TROG) based on dispersive propagation (DP), a new noninterferometric method for characterizing ultrashort optical pulses in amplitude and phase without the need for a short optical gating pulse.

Phosphorylation-Dependent Regulation of Mammalian Aquaporins

open access: yesCells, 2019
Water homeostasis is fundamental for cell survival. Transport of water across cellular membranes is governed by aquaporins—tetrameric integral membrane channels that are highly conserved throughout the prokaryotic and eukaryotic kingdoms.

Development and validation of a matlab software program for decoding the treatment errors in real-time position management™ Gating-generated breathing trace

open access: yesJournal of Medical Physics, 2020
Introduction: The Real-time Position Management™ (RPM) is used as a motion management tool to reduce normal tissue complication. However, no commercial software is available to quantify the “beam-on” errors in RPM-generated breathing traces.

Optically gated beating-heart imaging [PDF]

open access: yes, 2014
The constant motion of the beating heart presents an obstacle to clear optical imaging, especially 3D imaging, in small animals where direct optical imaging would otherwise be possible.
