Characterization of Transepithelial Potential Oscillations in the \u3cem\u3eDrosophila\u3c/em\u3e Malpighian Tubule [PDF]

, 2001
The Malpighian tubule of Drosophila melanogaster is a useful model system for studying the regulation of epithelial ion transport. In acutely isolated tubules, the transepithelial potential (TEP) undergoes large oscillations in amplitude with a period of

Structural Determinants of Skeletal Muscle Ryanodine Receptor Gating*

Journal of Biological Chemistry, 2013
Background: The molecular basis of calcium release by ryanodine receptors (RyRs) is incompletely understood. Results: Mutations predicted by a computational model alter Ca2+-dependent single RyR channel activity.

ER proteostasis meets mitochondrial function: contact sites as hubs of communication and therapeutic targets

The FEBS Journal, EarlyView.
Proteostasis ensures proper protein folding, modification, and degradation, while its impairment triggers ER stress. Chronic ER stress and maladaptive UPR via the CHOP–ERO1 axis remodel ERMCs, altering calcium signaling and mitochondrial metabolism.

Molecular genetic analysis for malignant hyperthermia : a thesis presented to Massey University in partial fulfilment of the requirements for the degree of Master of Science in Biochemistry [PDF]

, 2004
Malignant hyperthermia (MH) is a rare pharmacogenetic disorder in humans caused by inhalational general anaesthetics and depolarising muscle relaxants. An MH reaction shows abnormal calcium homeostasis in skeletal muscle leading to a hypermetabolic state

Applying lessons from limb muscle disuse and ageing to better understand ventilator‐induced diaphragm dysfunction

Experimental Physiology, EarlyView.
Abstract Mechanical ventilation (MV) is a life‐saving intervention applied to critically ill patients. A common consequence of MV is ventilator‐induced diaphragm dysfunction (VIDD), which is characterized by significant diaphragm atrophy and reduced contractile function. Older patients who receive MV are more likely to develop VIDD, have worse recovery,

DIAGNOSTICATION OF MALIGNANT HYPERTHERMIA IN SWINE

Scientific Papers Animal Science and Biotechnologies, 2023
Malignant hyperthermia (MH) causes neurological, liver, and kidney damage and death in humans and major economic losses in the swine industry. A single point mutation in the gene for the skeletal muscle ryanodine receptor (Ryrl) was found to be ...

Lifestyle modification in atrial fibrillation: Mechanisms, phenotypes and ablation outcomes

Experimental Physiology, EarlyView.
Abstract Atrial fibrillation (AF) is the most prevalent sustained cardiac arrhythmia and is associated with significant morbidity, mortality and healthcare utilization. Catheter ablation is increasingly used as a rhythm‐control intervention for patients with symptomatic paroxysmal and persistent AF, yet recurrence rates remain suboptimal.

Distance constraints on activation of TRPV4 channels by AKAP150-bound PKCα in arterial myocytes. [PDF]

, 2017
TRPV4 (transient receptor potential vanilloid 4) channels are Ca2+-permeable channels that play a key role in regulating vascular tone. In arterial myocytes, opening of TRPV4 channels creates local increases in Ca2+ influx, detectable optically as "TRPV4

Cardiac remodelling in type 2 diabetes: Pathophysiological mechanisms and opportunities for multiscale computational modelling and simulation

The Journal of Physiology, EarlyView.
Abstract figure legend Overview of multiscale cardiac remodelling in type 2 diabetes and how to model and simulate these changes using a human‐based, multiscale computational framework. Cardiac remodelling in type 2 diabetes occurs at ionic channel, protein, cellular, tissue and whole‐organ level, affecting the electrophysiological function, mechanical
