Locational and Directional Dependencies of Smooth Muscle Properties in Pig Urinary Bladder

Frontiers in Physiology, 2019
The urinary bladder is a distensible hollow muscular organ, which allows huge changes in size during absorption, storage and micturition. Pathological alterations of biomechanical properties can lead to bladder dysfunction and loss in quality of life. To

BDNF is a mediator of glycolytic fiber-type specification in mouse skeletal muscle

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance The brain-derived neurotrophic factor (BDNF) is essential to promote neuronal differentiation, plasticity, and survival. Altered BDNF expression is associated with several pathologies, including neuropsychiatric and neurodegenerative ...

Prediction of muscle fiber composition using multiple repetition testing

Biology of Sport, 2020
Direct determination of muscle fiber composition is invasive and expensive, with indirect methods also requiring specialist resources and expertise. Performing resistance exercises at 80% 1RM is suggested as a means of indirectly estimating muscle fiber ...

Improvac immunocastration affects the development of thigh muscles but not pectoral muscles in male chickens

Poultry Science, 2020
Improvac has been tentatively used to immune-castrate roosters. The aim of this study was to investigate whether Improvac affected skeletal muscle development in chickens.

ERK1/2 signaling induces skeletal muscle slow fiber-type switching and reduces muscular dystrophy disease severity

JCI Insight, 2019
MAPK signaling consists of an array of successively acting kinases. ERK1 and -2 (ERK1/2) are major components of the greater MAPK cascade that transduce growth factor signaling at the cell membrane.

The muscle fiber type–fiber size paradox: hypertrophy or oxidative metabolism? [PDF]

European Journal of Applied Physiology, 2010
An inverse relationship exists between striated muscle fiber size and its oxidative capacity. This relationship implies that muscle fibers, which are triggered to simultaneously increase their mass/strength (hypertrophy) and fatigue resistance (oxidative capacity), increase these properties (strength or fatigue resistance) to a lesser extent compared ...

Influence of skeletal muscle heterogeneity on autophagic signaling and response

Autophagy Reports
Skeletal muscle is a heterogeneous tissue composed of fibers with distinct contractile, metabolic, and molecular characteristics. This intrinsic heterogeneity influences how individual fibers respond to physiological stimuli, pathological stress, and ...

Muscle fiber type grouping does not change in response to prolonged resistance exercise training in healthy older men

Experimental Gerontology, 2023
Background: Ageing of skeletal muscle is characterized in some by muscle fiber type grouping due to denervation-reinnervation cycles, but the severity of fiber type grouping varies widely across individuals of the same chronological age.

Ovarian Sex Cord Stromal Tumors in Children and Adolescents—The European Standard Clinical Practice Recommendations

Pediatric Blood &Cancer, EarlyView.
ABSTRACT As part of the European Cooperative Study Group for Paediatric Rare Tumours initiative, we developed standard clinical practice guidelines for ovarian sex cord stromal tumors, based on comprehensive national and international cohort analyses, literature review, and a final expert consensus conference.
