Skeletal muscle mass and force decline with age, and the loss of muscle force precedes muscle atrophy. However, the underlying mechanisms remain unclear. Here, we investigated the role of the myosin co-chaperone, uncoordinated mutant number-45 myosin chaperone B (UNC45B), in...
BACKGROUND
Resistance training benefits patients with sarcopenia. However, trials demonstrating the effectiveness of Tai Chi combined with elastic band training are sparse, and the underlying neurocognitive mechanisms remain unclear.
METHODS
Forty-nine older sarcopenia patients (≥60 years) were recruited and randomly assigned to three groups:...
BACKGROUND
Longitudinal associations between age-related changes in body composition, physical performance and incident diabetes mellitus (DM) in older adults and the mediating role of branched-chain amino acids (BCAAs) remain understudied.
METHODS
This prospective cohort study included 4000 community-dwelling older adults at baseline. Longitudinal...
Intrinsic Capacity (IC) is defined as the composite of physical and mental abilities an individual possesses, encompassing five domains: cognition, psychological health, sensory function, vitality, and locomotion. This construct is central to the World Health Organization's framework for assessing functional...
Sarcopenia is characterized by age-related declines in muscle strength and mass, along with impaired physical function. It remains an unmet medical need, and there are no pharmacological interventions approved for this indication. The activation of growth hormone secretagogue receptor (GHSR)-1a,...
BACKGROUND
Preclinical models suggest alternating activation and inhibition of mechanistic target of rapamycin complex 1 (mTORC1) could enhance adaptation to exercise ('cycling hypothesis'). Whether this concept translates to older adults is unknown. This exploratory trial assessed whether once-weekly sirolimus (rapamycin) 6 mg...
Sarcopenia and pain are two highly prevalent conditions in aging populations, each exerting profound effects on mobility, independence, and quality of life. Emerging evidence demonstrates that these conditions are not merely coincidental but are closely interconnected through shared biological, mechanical,...
Sarcopenia associated with aging is a significant health issue affecting the quality of life in the elderly, yet research on effective treatments remains insufficient. This study aims to investigate the therapeutic effects and mechanisms of Semaglutide (Sema) in D-gal-induced aging-related...
BACKGROUND
Osteosarcopenia-the coexistence of osteopenia/osteoporosis and sarcopenia-is associated with numerous adverse health outcomes, but its association with intrinsic capacity (IC) remains unknown. We aimed to explore the associations of osteosarcopenia with IC and all-cause mortality in older adults.
METHODS
We conducted a cross-sectional...
Sarcopenia, a condition characterized by loss of skeletal muscle mass (SMM) and strength, contributes to frailty, disability, and increased healthcare burden, yet remains underdiagnosed due to limitations of conventional assessment methods. Wearable and mobile technologies have emerged as potential tools...
Cerebral palsy (CP) is the most common cause of childhood-onset physical disability. It results from injury to the developing brain and is characterized by motor impairments, muscle weakness, and fatigue. CP is commonly associated with marked deficits in muscle mass...
BACKGROUND
Sarcopenia, characterized by a progressive decline in muscle mass and function associated with aging, impacts around 10% of older adults worldwide and leads to heightened morbidity, increased hospitalization, and escalating healthcare costs. Early detection is crucial for timely intervention. The...
BACKGROUND
Studies have shown that sarcopenia and its related parameters are associated with cognition. Preclinical evidence suggests that myokines, such as irisin, Brain-Derived Neurotrophic Factor(BDNF), myostatin and Insulin-like Growth Factor-1(IGF-1) might explain this relationship. This study aimed to explore the associations...
Gut microbiome plays an important role in several metabolic, immune, and inflammatory pathways; however, there is limited evidence for its role in body composition and musculoskeletal health. Sarcopenia, defined as a loss of skeletal muscle mass and function, and obesity,...
