Adipose‐derived small extracellular vesicles exacerbate microvascular dysfunction in heart failure with preserved ejection fraction via mmu‐miR‐582‐3p‐mediated Rap1b suppression

Interdisciplinary Medicine, EarlyView.
This study reveals that small extracellular vesicles (sEVs) from visceral fat compromise coronary microcirculation in a mouse model of heart failure with preserved ejection fraction (HFpEF). The SGLT2 inhibitor canagliflozin emerges as a therapeutic strategy, improving cardiac function and endothelial health.

Prevalence and Mechanisms of Sustained Force Production in the Musculature of the Southern Alligator Lizard (Elgaria multicarinata)

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT The southern alligator lizard (Elgaria multicarinata) exhibits prolonged mate‐holding behavior. This behavior maybe be underpinned by a phenomenon known as sustained force, observed in the jaw muscles of this species, in which the muscle fails to relax between subsequent contractions.

Stochastic Ratcheting on a Funneled Energy Landscape is Necessary for Highly Efficient Contractility of Actomyosin Force Dipoles

, 2017
Current understanding of how contractility emerges in disordered actomyosin networks of non-muscle cells is still largely based on the intuition derived from earlier works on muscle contractility.

Biomarkers for the estimation of isoproterenol‐induced myocardial infarction: A review of key parameters

Journal of Intelligent Medicine, EarlyView.
Abstract The isoproterenol‐induced myocardial infarction model is a well‐established experimental approach for studying cardiac injury and testing potential protective treatments. By overstimulating beta‐adrenergic receptors, this model closely reproduces key features of human heart attacks, including oxidative damage, calcium imbalance, inflammatory ...

Clinical, manometric, genetic, and histologic associations in pediatric intestinal pseudo‐obstruction: A case series

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objectives Pediatric intestinal pseudo‐obstruction (PIPO) is a severe bowel motility disorder characterized by impaired propulsion of gastrointestinal contents without mechanical obstruction. PIPO encompasses congenital and acquired disorders, including neuropathies, myopathies, and mesenchymopathies.

The effect of acid sphingomyelinase inhibitor on oxidative stress, advance glycation end products and myosin phenotype of rat soleus muscle under conditions of functional unloading

Acta Biomedica Scientifica
Introduction. Functional unloading of  muscles is  accompanied by  slow-to-fast transformation of muscle myosin phenotype, an increase in acid sphingomyelinase (ASM) activity, ceramide, reactive oxygen species (ROS), and  advanced glycation end products (

Loganin, an Iridoid Glycoside, Alleviates Paclitaxel‐Induced Skeletal Muscle Toxicity by Enhancing Mitochondrial Function, Boosting Antioxidant Defenses, and Reducing Cellular Senescence

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Mitochondrial dysfunction and energy imbalance caused by chemotherapy are key contributors to skeletal muscle atrophy, which severely impacts the quality of life in cancer patients. Paclitaxel, a commonly used chemotherapeutic agent, is known to promote muscle wasting and cellular senescence, largely by impairing mitochondrial function.

Circadian Immunity and Vascular Inflammation in Cardiovascular Disease Chronotherapy Windows: Time for a Re‐Assessment

Med Research, EarlyView.
ABSTRACT Circadian rhythms orchestrate cardiovascular physiology by regulating immune and inflammatory pathways. Disruption of these rhythms profoundly alters vascular homeostasis, thereby promoting the onset and progression of cardiovascular diseases (CVD).

Mitochondrial Sensitivity to Submaximal [ADP] Following Bed Rest: A Novel Two‐Phase Approach Associated With Fibre Types

Journal of Cachexia, Sarcopenia and Muscle
Background We recently demonstrated that following a 10‐day exposure to inactivity/simulated microgravity impairments of oxidative metabolism were located ‘upstream’ of mitochondrial function, as evaluated by maximal ADP‐stimulated mitochondrial ...

The major myosin-binding domain of skeletal muscle MyBP-C (C protein) resides in the COOH-terminal, immunoglobulin C2 motif. [PDF]

, 1993
A common feature shared by myosin-binding proteins from a wide variety of species is the presence of a variable number of related internal motifs homologous to either the Ig C2 or the fibronectin (Fn) type III repeats.
