Gating Ritual: Simulations of Gating in Glutamate-Gated Chloride Channel [PDF]
Biophysical Journal, 2015 Ligand-gated ion channels (LGICs) are responsible for converting chemical signals to electrical ones in the nerve system, which is a key element in the fast synaptic signal transmission. The first crystal structures of prokaryotic homologs were solved a few years ago, and today there are many more structures available - including a human one.

Graphene field effect transistors with ferroelectric gating
, 2010 Recent experiments on ferroelectric gating have introduced a novel functionality, i.e. nonvolatility, in graphene field effect transistors. A comprehensive understanding in the non-linear, hysteretic ferroelectric gating and an effective way to control ...

Optically gated beating-heart imaging [PDF]
, 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.

Mechanism of activation at the selectivity filter of the KcsA K+ channel
eLife, 2017 Potassium channels are opened by ligands and/or membrane potential. In voltage-gated K+ channels and the prokaryotic KcsA channel, conduction is believed to result from opening of an intracellular constriction that prevents ion entry into the pore.

Gating currents indicate complex gating of voltage-gated proton channels [PDF]
Proceedings of the National Academy of Sciences, 2018 The voltage-gated proton channel (HV1) is a unique molecule that resides at the interface between ion channels and bioenergetic molecules that use proton gradients to store or transduce energy. HV1 plays key roles in the health and disease of diverse tissues and species (1). Important information regarding the physical components of ion-channel gating (

Gating-by-tilt of mechanosensitive membrane channels
, 2003 We propose an alternative mechanism for the gating of biological membrane channels in response to membrane tension that involves a change in the slope of the membrane near the channel. Under biological membrane tensions we show that the energy difference

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

Cells, 2015 Each positive well in ELISPOT assays contains spots of variable sizes that can range from tens of micrometers up to a millimeter in diameter. Therefore, when it comes to counting these spots the decision on setting the lower and the upper spot size ...
