Anoxic spreading depolarization in the neonatal rat cortex in vitro

Frontiers in Cellular Neuroscience, 2023
Anoxic spreading depolarization (aSD) is a hallmark of ischemic injury in the cerebral cortex. In adults, aSD is associated with rapid and nearly complete neuronal depolarization and loss of neuronal functions.

A new approach to immunoFET operation [PDF]

, 1990
A new method is presented for the detection of an immunological reaction taking place in a membrane, which covers the gate area of an ISFET. By stepwise changing the electrolyte concentration of the sample solution, a transient diffusion of ions through ...

ASCs-Exosomes Recover Coupling Efficiency and Mitochondrial Membrane Potential in an in vitro Model of ALS

Frontiers in Neuroscience, 2019
The amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder characterized by motoneurons death. Mutations in the superoxide dismutase 1 (SOD1) protein have been identified to be related to the disease.

Evaluation of the Anticancer Properties of Geranyl Isovalerate, an Active Ingredient of Argyreia nervosa Extract in Colorectal Cancer Cells

Frontiers in Pharmacology, 2021
Chemotherapy is a general treatment procedure for cancer. The diversity in cancer incidence and the failure of therapy due to chemoresistance lead to increased cancer-related deaths.

Oxygen reduction at the silver/hydroxide-exchange membrane interface [PDF]

, 2008
A solid-state cell is used to study the electrocatalysis of oxygen reduction at the silver/hydroxide-exchange membrane interface. The catalyst/membrane interface exhibits improved performance in comparison to a catalyst/aqueous sodium hydroxide interface.

Cromakalim (BRL 34915) restores in vitro the membrane potential of depolarized human skeletal muscle fibres [PDF]

, 1989
The purpose of the present study was to analyze the effects of cromakalim (BRL 34915), a potent drug from a new class of drugs characterized as K+ channel openers, on the electrical activity of human skeletal muscle.

Introducing Membrane Charge and Membrane Potential to T Cell Signaling

Frontiers in Immunology, 2017
While membrane models now include the heterogeneous distribution of lipids, the impact of membrane charges on regulating the association of proteins with the plasma membrane is often overlooked.

Determination of a Robust Assay for Human Sperm Membrane Potential Analysis

Frontiers in Cell and Developmental Biology, 2019
Mammalian sperm must undergo a complex process called capacitation in order to fertilize the egg. During this process, hyperpolarization of the sperm plasma membrane has been mostly studied in mouse, and associated to its importance in the preparation to

Applying a potential across a biomembrane: electrostatic contribution to the bending rigidity and membrane instability

, 2007
We investigate the effect on biomembrane mechanical properties due to the presence an external potential for a non-conductive non-compressible membrane surrounded by different electrolytes.

Subthreshold dynamics of the neural membrane potential driven by stochastic synaptic input [PDF]

, 2002
In the cerebral cortex, neurons are subject to a continuous bombardment of synaptic inputs originating from the network's background activity. This leads to ongoing, mostly subthreshold membrane dynamics that depends on the statistics of the background ...
