Training benefits consequent to 8-weeks of kettlebell training [PDF]

, 2012
This study was designed to examine the changes in aerobic capacity and muscular strength consequent to 8 weeks of kettlebell training. Seventeen subjects (9 males, 8 females) completed 1 repetition maximum (1RM) testing for one-arm shoulder press, leg ...

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

The effect of high-dose vitamin D supplementation on muscular function and quality of life in postmenopausal women—A randomized controlled trial [PDF]

, 2017
Objective: Observational studies have suggested positive associations between serum 25-hydroxyvitamin D (25(OH)D) levels and muscular strength, balance and quality of life.

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

EFFECTS OF A STRUCTURED PHYSICAL EXERCISE PROGRAM ON THE DEVELOPMENT OF MUSCULAR STRENGTH IN PRISON POPULATIONS

Studia Universitatis Babeş-Bolyai: Educatio Artis Gymnasticae
Physical inactivity represents a major concern in prison environments, where limited movement opportunities contribute to decreased physical fitness and muscular strength.

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Colorectal cancer‐derived FGF19 is a metabolically active serum biomarker that exerts enteroendocrine effects on mouse liver

Molecular Oncology, EarlyView.
Meta‐transcriptome analysis identified FGF19 as a peptide enteroendocrine hormone associated with colorectal cancer prognosis. In vivo xenograft models showed release of FGF19 into the blood at levels that correlated with tumor volumes. Tumoral‐FGF19 altered murine liver metabolism through FGFR4, thereby reducing bile acid synthesis and increasing ...

Effects on strength of vibratory exercise compared to walking in postmenopausal women [PDF]

, 2008
A major problem associated with advanced adult age is the remarkable decline in functional capacity and the associated loss of independence (1). Muscle strength of the lower extremities is a major neuromuscular determinant of these losses and mobility (2)
