Activation of Mitochondrial Ca2+ Oscillation and Mitophagy Induction by Femtosecond Laser Photostimulation

open access: yesBio-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

Blood‐based proteomic profiling reveals context‐dependent changes in BCL2‐associated signaling during taxane therapy in breast cancer patients

open access: yesFEBS Open Bio, EarlyView.
Chemotherapy side effects significantly impact cancer survivors' quality of life. Using protein levels in blood samples from breast cancer patients before and after 12 weeks of taxane treatment, we detected treatment‐dependent changes in calcium signaling and aging pathways associated with cancer recurrence.

Molecular Dynamics Simulation Study of Solid Vibration Permeation in Microporous Amorphous Silica Network Voids

open access: yesMembranes, 2019
Microporous silica membranes have silica polymer network voids smaller than 3 Å where only small gas molecules such as helium (2.6 Å) and hydrogen (2.89 Å) can be transported.

Fatigue Crack Initiation and Growth in Nanocrystalline Ni at Multiple Length‐Scales

open access: yesAdvanced Engineering Materials, EarlyView.
Overview of miniaturized in situ SEM fatigue setup and resultant fatigue crack growth data for nanocrystalline Ni. The presented study focuses on the analysis of fatigue crack growth rate (FCGR) in focused ion beam‐notched microcantilevers prepared from nanocrystalline (NC) Ni as a model material.

Mitogen‐induced oscillations of membrane potential and Ca2+ in human fibroblasts [PDF]

open access: yesFEBS 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

Speeding-up Screening of S1 SARS-CoV2 Inhibitors by Nanostructured Biomimetic ACE2 Sensors Based on a Superconductive Josephson Junction Toroidal Array Oscillating Effect

open access: yesECS Sensors Plus
We 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

open access: yesFrontiers 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

Experimental and Numerical Modal Analysis of Composite Sandwich Structures Using Surfboards as Model Systems

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents an experimental and numerical modal investigation of composite sandwich structures using surfboards as model systems. By comparing different core materials and reinforcement strategies, the study demonstrates how local stiffeners influence vibrational response and introduce characteristic modal features, highlighting modal ...

Swelling and membrane potential dynamics of glial Müller cells

open access: yes, 2022
Presently a detailed biophysical model describing reversible and irreversible swelling dynamics of Muller cells (MC) is reported. The model includes a biophysical block of ionic and neutral species transport via MC mem-brane, water transport induced by ...
