Dynamic response of model lipid membranes to ultrasonic radiation force. [PDF]

open access: yesPLoS ONE, 2013
Low-intensity ultrasound can modulate action potential firing in neurons in vitro and in vivo. It has been suggested that this effect is mediated by mechanical interactions of ultrasound with neural cell membranes.

Organelle calcium-derived voltage oscillations in pacemaker neurons drive the motor program for food-seeking behavior in Aplysia

open access: yeseLife, 2021
The expression of motivated behaviors depends on both external and internally arising neural stimuli, yet the intrinsic releasing mechanisms for such variably occurring behaviors remain elusive. In isolated nervous system preparations of Aplysia, we have

Orexin enhances firing activities of neurons in neonatal rat sublaterodorsal tegmental nucleus

open access: yesDi-san junyi daxue xuebao, 2020
Objective To investigate the effect and underlying mechanism of orexin in modulating the firing activties of sublaterodorsal tegmental nucleus (SLD) neurons and its possible role in mediating rapid eye movement (REM) sleep regulation.

Numerical Investigation of T-Shaped Microfluidic Oscillator with Viscoelastic Fluid

open access: yesMicromachines, 2021
Oscillatory flow has many applications in micro-scaled devices. The methods of realizing microfluidic oscillators reported so far are typically based on the impinging-jet and Coanda effect, which usually require the flow Reynolds number to be at least at

Lipidomics in research on yeast membrane lipid homeostasis [PDF]

open access: yes, 2017
Mass spectrometry is increasingly used in research on membrane lipid homeostasis, both in analyses of the steady state lipidome at the level of molecular lipid species, and in pulse-chase approaches employing stable isotope-labeled lipid precursors ...

Dynamics of sodium current mediated early afterdepolarizations

open access: yesHeliyon, 2017
Early afterdepolarizations (EADs) have been attributed to two primary mechanisms: 1) recovery from inactivation of the L-type calcium (Ca) channel and/or 2) spontaneous Ca release, which depolarizes the membrane potential through the electrogenic sodium ...

A design principle of spindle oscillations in mammalian sleep

open access: yesiScience, 2022
Summary: Neural oscillations are mainly regulated by molecular mechanisms and network connectivity of neurons. Large-scale simulations of neuronal networks have driven the population-level understanding of neural oscillations.

The Membrane Steps of Bacterial Cell Wall Synthesis as Antibiotic Targets [PDF]

open access: yes, 2016
Peptidoglycan is the major component of the cell envelope of virtually all bacteria. It has structural roles and acts as a selective sieve for molecules from the outer environment. Peptidoglycan synthesis is therefore one of the most important biogenesis

Influence of Membrane Vibration on Particles Rejection Using a Slotted Pore Membrane Microfiltration

open access: yes, 2021
A new method is proposed to increase the rejection in microfiltration by applying membrane oscillation, using a new type of microfiltration membrane with slotted pores.
