A model for cooperative gating of L-type Ca2+ channels and its effects on cardiac alternans dynamics.

PLoS Computational Biology, 2018
In ventricular myocytes, membrane depolarization during the action potential (AP) causes synchronous activation of multiple L-type CaV1.2 channels (LTCCs), which trigger the release of calcium (Ca2+) from the sarcoplasmic reticulum (SR).

Near‐Infrared Light‐Activated Polydopamine Nanoparticles Conjugated With Transferrin Peptides for Enhanced Brain Accumulation

Advanced Healthcare Materials, EarlyView.
This study demonstrates that Tf‐PDA NPs combine a receptor‐mediated targeting with mild photothermal activation to enhance nanoparticle accumulation in the brain. NIR‐activated Tf‐PDA NPs increase BBB permeability to NPs in vitro and in vivo without inducing cytotoxicity or adverse immune responses.

Plasma membrane compartmentation in Saccharomyces cerevisiae [PDF]

, 2009
In the plasma membrane of cells the complex variety of components is sorted into subcompartments, microdomains and nanoclusters. We only begin to understand the principles of this higher order.

Spike-timing dependent plasticity and feed-forward input oscillations produce precise and invariant spike phase-locking

Frontiers in Computational Neuroscience, 2011
In the hippocampus and the neocortex, the coupling between local field potential (LFP) oscillations and the spiking of single neurons can be highly precise, across neuronal populations and cell types. Spike phase (i.e.

Inositol trisphosphate‐induced membrane potential oscillations in Xenopus oocytes.

The Journal of Physiology, 1988
1. The role of inositol 1,4,5‐trisphosphate (Ins1,4,5P3) in controlling the membrane potential oscillations induced by acetylcholine in Xenopus oocytes was investigated by studying the effect of injecting Ins1,4,5P3. 2. Perfusing Xenopus oocytes with low concentrations of acetylcholine (less than or equal to 1 x 10(‐7) M) induced regular oscillations ...

Generating Unconventional Spin‐Orbit Torques With Patterned Phase Gradients in Tungsten Thin Films

Advanced Materials, EarlyView.
ABSTRACT A key aim in spintronics is to achieve current‐induced magnetization switching via spin‐orbit torques without external magnetic fields. For this, the focus of recent work has been on introducing controlled lateral gradients across ferromagnet/heavy‐metal devices, giving variations in thickness, composition, or interface quality.

Effect of humic-acid fouling on membrane distillation

, 2016
Membrane distillation (MD) can concentrate non-volatile solutes or remove volatiles and dissolved gases from an aqueous feed. A microporous hydrophobic membrane provides a barrier between the hot feed and cold distillate.
