Voltage‐gated potassium channels mediate thyroid hormone control of skeletal muscle excitability

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Thyroid hormone (TH)‐dependent remodelling of potassium (K+) channel networks regulates skeletal muscle (SkM) excitability. Triiodothyronine (T3), locally generated from thyroxine (T4) by type 2 deiodinase (D2), binds thyroid hormone receptors (TRα/β) and modulates transcription via thyroid response elements (TREs).

The Impact of Ageing on Skeletal Muscle: Roles of Mitochondrial Dysregulation, Systemic Communication, and Exercise

open access: yesJournal of Cellular Physiology, Volume 241, Issue 8, August 2026.
ABSTRACT Ageing is a major risk factor for degenerative diseases, including sarcopenia, which is characterized by a progressive loss of skeletal muscle mass and function, frailty, and is associated with increased mortality. Skeletal muscle regeneration relies on muscle stem cells and efficient communication with cellular microenvironment.

Downstream Pathways of Dystrophin Deficiency in Duchenne Muscular Dystrophy: Implications for Muscle Degeneration and Regeneration

open access: yesJournal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 4, August 2026.
ABSTRACT Background Duchenne muscular dystrophy (DMD) is the most common and severe form of muscular dystrophy, primarily affecting skeletal muscle and leading to premature death. Although the loss of dystrophin has long been recognised as the primary cause of the disease, no definitive cure is currently available. As a consequence, therapeutic efforts

Imeglimin Attenuates Skeletal Muscle Atrophy in Mouse Models of Obesity and Ageing

open access: yesJournal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 4, August 2026.
ABSTRACT Background Sarcopenia is a major contributor to frailty and mortality in ageing and obesity and is tightly linked to metabolic dysfunction. Imeglimin is a first‐in‐class oral hypoglycaemic agent targeting mitochondrial function; however, despite the central role of mitochondria in skeletal muscle homeostasis, its effects on skeletal muscle ...

Early and Divergent Lipid Mediator Remodelling in Fast Versus Slow Skeletal Muscles of Female hSOD1G93A Mice

open access: yesJournal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 4, August 2026.
ABSTRACT Background Skeletal muscle atrophy in amyotrophic lateral sclerosis (ALS) drives loss of muscle strength, function and quality of life in ALS patients. The endocannabinoid system (ECS) regulates muscle homeostasis via regenerative and metabolic processes, and although ECS alterations have been reported in ALS neural tissues, ECS remodelling ...

Smile Asymmetry and Eyelid Closure Following Temporalis Muscle Transfer for Facial Reanimation: A Systematic Review and Meta‐Analysis

open access: yesThe Laryngoscope, Volume 136, Issue 8, Page 3314-3324, August 2026.
This systematic review and meta‐analysis of 53 studies and 1354 patients evaluates the outcomes of temporalis muscle transfer in facial nerve paralysis. Our results show that temporalis muscle transfer can restore smile asymmetry, oral commissure movement, and eyelid closure—findings that are translated to clinician‐rated assessments.

Effect of a Single Session of Intense Resistance Exercise with Glutamine Supplementation on the Relative Expression of Alpha and IIX Isoforms of Fast-Twitch Myosin Heavy Chain Gene in Male Rats [PDF]

open access: yesمجله دانشگاه علوم پزشکی گرگان
Background and Objective: Neural, hormonal, and mechanical factors regulate the expression of fast-twitch isoforms in developing and mature muscle fibers. The transcriptional mechanisms responsible for regulating the gene expression of myosin heavy chain

Characterizing Metabolic and Compositional Heterogeneity of Calf Muscle Using CEST MRI at 3 T

open access: yesNMR in Biomedicine, Volume 39, Issue 8, August 2026.
This study used 3 T CEST MRI to characterize metabolic and compositional heterogeneity in eight healthy calf muscles, focusing on amide, PCr, rNOE, and MT contrasts. Distinct signatures emerged between deep stabilizer and superficial powerhouse muscles. Significant correlations with age, fat content, BMI, and strength (e.g., rNOE vs. strength) revealed

Activation of the Lactate Receptor GPR81 Ameliorates Senescence Hallmarks and Improves Muscle Function in Cellular and Progeroid Models of Aging

open access: yesAging Cell, Volume 25, Issue 8, August 2026.
Skeletal muscle aging is associated with a decrease in expression of the lactate receptor GPR81. Treating senescent myoblasts in vitro and progeric mice in vivo with GPR81 agonist decreases intramyocellular lipid accumulation and reverses hallmarks of aging. ABSTRACT Skeletal muscle aging is associated with increased lipid accumulation, or myosteatosis,

Physiological Basis of Sex Differences in Human Performance and Exercise‐Associated Pathology

open access: yesClinical Endocrinology, Volume 105, Issue 2, Page 151-162, August 2026.
ABSTRACT The presence of sex differences in human physical performance is well‐established and shaped by distinct endocrine, anatomical and physiological mechanisms. Despite sustained advances, our understanding of how inherent biological factors drive variations in exercise capacity and related pathologies is still developing.
