BACKGROUND
Amyotrophic lateral sclerosis (ALS) is characterized by progressive muscle wasting and functional decline. Prognostic assessment in clinical practice relies largely on functional scales and traditional anthropometric measures. The prognostic relevance of muscle mass, muscle strength and sarcopenia in ALS remains...
BACKGROUND
Skeletal muscle injuries significantly impair mobility and function, yet effective therapeutic interventions remain limited. Both eccentric exercise (EE) and concentric exercise (CE) promote muscle repair, but the underlying mechanisms are not fully understood. Muscle-derived extracellular vesicles (mEVs) have emerged as...
BACKGROUND
Ultra-endurance sports are increasingly popular, yet the long-term physiological consequences of sustained extreme training loads remain poorly understood. In particular, the effects of prolonged ultra-endurance exercise on skeletal muscle structure, function and molecular remodelling are largely unknown. This case study...
Sarcopenia is an age-related pathological syndrome characterized by progressive and generalized loss of skeletal muscle mass and function, with muscle atrophy representing its cardinal pathological hallmark. Ferroptosis, an iron-dependent regulated cell death, has been implicated in the pathogenesis of muscle...
BACKGROUND
Sarcopenia is highly prevalent in decompensated cirrhosis and independently predicts adverse outcomes. Although nutritional therapy is guideline-recommended, evidence comparing specialist dietitian-supervised nutritional care with routine physician-delivered dietary advice remains limited.
AIM
To compare the efficacy of dietitian-supervised intensive nutritional therapy with physician-led...
In mammals, nearly every cell contains an intrinsic circadian clock that functions both as a timekeeping system and an environmental sensor, integrating external cues to maintain alignment between internal physiology and the external environment. While the core clock machinery is...
Cancer cachexia, affecting up to 80% of patients with advanced cancer, is characterized by metabolic and inflammatory dysregulation driven by tumour- and host-derived factors. Although cytokines are central to cachexia pathogenesis, their circulating profiles and transcriptional relevance across models and...
BACKGROUND & AIMS
Cancer cachexia is associated with systemic skeletal muscle loss and poor survival; however, early muscle changes preceding systemic muscle loss remain unclear. Therefore, this study aimed to determine whether tongue-complex muscle area (TCMA) can serve as an early...
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...
Sarcopenia, an age-related degenerative disease of skeletal muscle, is closely associated with osteoporosis and other bone disorders, partly due to dysregulated endocrine function of skeletal muscle. However, the specific cellular sources and molecular mechanisms driving this pathological secretory phenotype remain...
BACKGROUND
Skeletal muscle atrophy is a frequent comorbidity of metabolic disorders and chronic diseases, and despite its high prevalence, no pharmacological therapy is available, representing a major unmet clinical need. Adiponectin and its receptors are key regulators of skeletal muscle metabolism,...
Cancer cachexia is characterised by progressive skeletal muscle wasting and dysfunction, yet the early events that precede overt muscle wasting remain poorly defined. Here, we utilised a time-coursed C26 carcinoma model in male and female mice to define the pre-cachectic...
BACKGROUND
Dietary and pharmacologic weight loss can reduce skeletal muscle. Whether calcium beta-hydroxy-beta-methylbutyrate (CaHMB)-enriched supplementation preserves muscle while promoting fat loss in adults with obesity remains uncertain. We evaluated a CaHMB-enriched nutritional supplement during energy restriction.
METHODS
In this randomized, double-blind, controlled trial,...
BACKGROUND
The serine/threonine kinase AKT is a key regulator of glucose and energy metabolism. Prevailing dogma suggests that AKT is an obligate intermediate for glucose uptake in all metabolic tissues and that impaired AKT signalling is a major molecular driver of...
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...
