Bio-Protocol, 2022 Ultra-precise stimulation solely to individual mitochondria, without any influence to the whole cell, is quite difficult by traditional biochemical reagents. In mitophagy research, the mitochondria and even the whole cell usually suffer irreversible

Structure and Oscillation of Membrane Potential in Block Copolypeptide Membranes.
membrane, 1997 Membranes solvent-cast from the triblock copolypeptide poly (γ-benzyl-L-glutamate) x-poly (L-leucine) y-poly (γ-benzyl-L-glutamate) x, in which the mole ratio of the constituent blocks was properly tailored, displayed a mesophase structure comprised of cylindrical domains of poly (γ-benzyl-L-glutamate) in a continuous matrix of poly (L-leucine ...

Mitogen‐induced oscillations of membrane potential and Ca2+ in human fibroblasts [PDF]
FEBS Letters, 1990 Using the whole‐cell technique, we have measured recurring hyperpolarizations induced by fetal calf serum and bradykinin in human fibroblasts. By coupling fura‐2 microfluorimetry to electrophysiology, we have also measured directly cytosolic Ca2+ and found that Ca2+ oscillations occur in synchrony with membrane currents. Mitogen stimulation of cells in

Spontaneous Basilar Membrane Oscillation and Otoacoustic Emission at 15 kHz in a Guinea Pig [PDF]
, 2004 A spontaneous otoacoustic emission (SOAE) measured in the ear canal of a guinea pig was found to have a counterpart in spontaneous mechanical vibration of the basilar membrane (BM).

Advanced Functional Materials, EarlyView.Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

ECS Sensors PlusWe present a method for integrating a quantum superconductive oscillation effect, induced by a potential S1 SARS-CoV-2 inhibitor, which achieves a 99.992% blockade of S1 virus communication with a biomimetic angiotensin-converting enzyme 2 (ACE2) sensor.

DC-shifts in amplitude in-field generated by an oscillatory interference model of grid cell firing
Frontiers in Systems Neuroscience, 2014 Oscillatory interference models propose a mechanism by which the spatial firing pattern of grid cells can arise from the interaction of multiple oscillators that shift in relative phase. These models produce aspects of the physiological data such as the

Role of membrane potential in vasomotion of isolated pressurized rat arteries
, 2002 Vasomotion, the phenomenon of vessel diameter oscillation, regulates blood flow and resistance. The main parameters implicated in vasomotion are particularly the membrane potential and the cytosolic free calcium in smooth muscle cells.
