Organelle Optogenetics: Direct Manipulation of Intracellular Ca2+ Dynamics by Light

Frontiers in Neuroscience, 2018
As one of the ubiquitous second messengers, the intracellular Ca2+, has been revealed to be a pivotal regulator of various cellular functions. Two major sources are involved in the initiation of Ca2+-dependent signals: influx from the extracellular space

Genetic Biomarkers in the Risk Assessment of Sudden Cardiac Events: A Personalized Approach

iNew Medicine, EarlyView.
Genetic insights into the risk assessment of sudden cardiac events. ABSTRACT Sudden cardiac events are the leading cause of death worldwide. Conventional risk stratification methods, which largely depend on clinical history, imaging, and electrocardiography, are usually inadequate for identifying high‐risk individuals, especially those without visible ...

Calcium sparks in arterial smooth muscle cells regulate vascular tone

Journal of Biological Research, 2002
It is named Ca2+ sparks a local, rapid and transient Ca2+ release from sarcoplasmic reticulum (SR) by the opening of ryanodine-sensitive (RyR) channels. RyR channels localized in SR are found in all muscle cell types (cardiac, skeletal, smooth) and many

Review of Congenital Myasthenic Syndrome Caused by Pathogenic Variants in GFPT1

Muscle &Nerve, EarlyView.
ABSTRACT Glutamine:fructose‐6‐phosphate transaminase 1 (GFPT1) catalyzes the first and rate‐limiting step of the hexosamine biosynthetic pathway (HBP) to generate UDP‐GlcNAc. GFPT1 exon 9 is specifically spliced in in striated muscles, which makes a long isoform of GFPT1 (GFPT1‐L).

Myasthenia Gravis and Thymoma

Muscle &Nerve, EarlyView.
ABSTRACT Thymoma is the most common tumor of the anterior mediastinum. Approximately 20%–30% of patients with a thymoma develop myasthenia gravis (MG), and an additional one third may possess positive acetylcholine receptor (AChR) antibodies without MG.

Proteomic Profiling of Myofiber Repair Annexins and Their Role in Duchenne Muscular Dystrophy

PROTEOMICS, EarlyView.
ABSTRACT Myofiber regeneration and membrane repair play crucial roles in maintaining the continuous physiological functioning of the neuromuscular system. A swift and efficient repair mechanism enables the rapid restoration of sarcolemmal integrity following cellular impairment in damaged skeletal muscles.

Dysfunction of the sarcoplasmic reticulum in polymyositis [PDF]

Arthritis & Rheumatism, 1984
AbstractThe transport of calcium in vesicles of sarcoplasmic reticulum isolated from muscle specimens from 6 patients with early, active polymyositis and from 11 controls was examined. The time courses of calcium uptake and calcium‐dependent ATPase activity were measured simultaneously.

Accelerating virtual patient generation with a Bayesian optimization and machine learning surrogate model

CPT: Pharmacometrics &Systems Pharmacology, Volume 14, Issue 3, Page 486-494, March 2025.
Abstract The pharmaceutical industry has increasingly adopted model‐informed drug discovery and development (MID3) to enhance productivity in drug discovery and development. Quantitative systems pharmacology (QSP), which integrates drug action mechanisms and disease complexities to predict clinical endpoints and biomarkers is central to MID3.

A proposed role for non-junctional transverse tubules in skeletal muscle as flexible segments allowing expansion of the transverse network

European Journal of Translational Myology, 2019
Using a variety of technical approaches, we have detected the presence of continuous triads that cover the entire length of T tubules in the main white body muscles of several small fish.

Penile intracavernosal injection of succinylcholine for laryngospasm management during hypospadias repair

UroPrecision, EarlyView.
Abstract Background Laryngospasm is a serious anesthetic complication that can lead to acute airway obstruction and hypoxemia. Standard management involves deepening anesthesia and administering succinylcholine intravenously (IV) or intramuscularly (IM). However, if IV access is lost or IM drug delivery is too slow, alternative routes are required.
