The electrophysiology of the betacell based on single transmembrane protein characteristics [PDF]

arXiv, 2007
The electrophysiology of betacells is at the origin of insulin secretion. Betacells exhibit a complex behaviour upon stimulation with glucose including repeated and uninterrupted bursting. Mathematical modelling is most suitable to improve knowledge about the function of various transmembrane currents provided the model is based on reliable data.

An In-Silico Study on Integrated Mechanisms of Mechano-Electric Coupling in Ischaemic Arrhythmogenesis [PDF]

arXiv, 2023
Heterogeneous mechanical dyskinesis during acute myocardial ischaemia is thought to contribute to arrhythmogenic alterations to cardiac electrophysiology. Various forms of mechano-electric coupling (MEC) mechanisms have been suggested to contribute to these changes, with two primary mechanisms being: (1) myofilament-dependent calcium release events ...

Ultra‐Flexible µ‐ECoG Arrays Based on PEDOT:PSS Micropillars

Advanced Materials Interfaces, EarlyView.
This work demonstrates an efficient procedure for fabricating ultra‐flexible neural interfaces endowed with micropatterned microelectrodes to increase surface area and characterized by extremely low impedance values to enable high‐quality recordings. The home‐built device has been shown to record somatosensory evoked potentials in vivo with exceptional

Force-controlled electrophysiology

BIO Web of Conferences, 2016
Glass micropipettes are the typical instrument for intracellular injection, patch clamping or extracellular deposition of liquids into viable cells. The micro pipette is thereby slowly approached to the cell by using micro manipulators and visual control

Early Repolarization Syndrome: Diagnostic and Therapeutic Approach

Frontiers in Cardiovascular Medicine, 2018
An early repolarization pattern can be observed in 1% up to 13% of the overall population. Whereas, this pattern was associated with a benign outcome for many years, several more recent studies demonstrated an association between early repolarization and

Ablation index, a novel marker of ablation lesion quality: prediction of pulmonary vein reconnection at repeat electrophysiology study and regional differences in target values

Europace, 2016
Aims Force-Time Integral (FTI) is commonly used as a marker of ablation lesion quality during pulmonary vein isolation (PVI), but does not incorporate power.

Palmitoylation: A Fatty Regulator of Myocardial Electrophysiology

Frontiers in Physiology, 2020
Regulation of cardiac physiology is well known to occur through the action of kinases that reversibly phosphorylate ion channels, calcium handling machinery, and signaling effectors.

Requirements for storing electrophysiology data [PDF]

arXiv, 2016
The purpose of this document is to specify the basic data types required for storing electrophysiology and optical imaging data to facilitate computer-based neuroscience studies and data sharing. These requirements are being developed within a working group of the Electrophysiology Task Force in the International Neuroinformatics Coordinating Facility (

Bayesian methods for event analysis of intracellular currents [PDF]

, 2016
Investigation of neural circuit functioning often requires statistical interpretation of events in subthreshold electrophysiological recordings. This problem is non-trivial because recordings may have moderate levels of structured noise and events may have distinct kinetics.

The Role of Silicon Technology in Organ‐On‐Chip: Current Status and Future Perspective

Advanced Materials Technologies, EarlyView.
This review explores the potential of silicon micro‐nanofabrication technologies in advancing organ‐on‐chip systems. The integration of actuation and sensing modalities, highlight emerging technologies is discussed for combining silicon‐based and polymer‐based components, and emphasize the need for robust, high‐throughput, and customizable organ‐on ...
