Bioelectrical impedance vectors analysis (BIVA) in older adults according to level of physical activity and muscle strength: a comparison of classic and specific approaches

Frontiers in Aging
IndroductionBioelectrical Impedance Analysis (BIA) is a widely used method to assess body composition. Traditional BIA models use predictive equations without considering individual characteristics such as age, sex, and activity level.

Normal inflammation and regeneration of muscle following injury require osteopontin from both muscle and non-muscle cells

Skeletal Muscle, 2019
Background Osteopontin is secreted by skeletal muscle myoblasts and macrophages, and its expression is upregulated in muscle following injury. Osteopontin is present in many different structural forms, which vary in their expression patterns and effects ...

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Function of mTOR complex 1 and 2 in skeletal muscle [PDF]

, 2009
Growth of an organ during development and during adaptation in the adult can be controlled by alterations either in the number or the size of cells. The two mechanisms are fundamentally different and require distinct regulation.

Diversification of the muscle proteome through alternative splicing

Skeletal Muscle, 2018
Background Skeletal muscles express a highly specialized proteome that allows the metabolism of energy sources to mediate myofiber contraction. This muscle-specific proteome is partially derived through the muscle-specific transcription of a subset of ...

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Cromakalim (BRL 34915) restores in vitro the membrane potential of depolarized human skeletal muscle fibres [PDF]

, 1989
The purpose of the present study was to analyze the effects of cromakalim (BRL 34915), a potent drug from a new class of drugs characterized as K+ channel openers, on the electrical activity of human skeletal muscle.

Nicotinamide phosphoribosyltransferase (Nampt) in Lateral Hypothalamus Maintains Skeletal Muscle Functions Through Lactate‐Mediated Calcium Signalling in Male Mice

Journal of Cachexia, Sarcopenia and Muscle
Background Sarcopenia has become an urgent socioeconomic problem in rapidly aging societies. The pathogenesis of age‐associated sarcopenia is not fully understood and no effective therapeutic strategies have been developed to date.

Weightlifting outperforms voluntary wheel running for improving adiposity and insulin sensitivity in obese mice

Journal of Sport and Health Science
Background: Exercise is an effective intervention for obesity and type 2 diabetes, with significant physiological benefits over pharmacological interventions.

SMCHD1 regulates a limited set of gene clusters on autosomal chromosomes

Skeletal Muscle, 2017
Background Facioscapulohumeral muscular dystrophy (FSHD) is in most cases caused by a contraction of the D4Z4 macrosatellite repeat on chromosome 4 (FSHD1) or by mutations in the SMCHD1 or DNMT3B gene (FSHD2).
