Filament compliance influences cooperative activation of thin filaments and the dynamics of force production in skeletal muscle. [PDF]
Striated muscle contraction is a highly cooperative process initiated by Ca²⁺ binding to the troponin complex, which leads to tropomyosin movement and myosin cross-bridge (XB) formation along thin filaments. Experimental and computational studies suggest

Aprotinin reduces cardiac troponin I release and inhibits apoptosis of polymorphonuclear cells during off-pump coronary artery bypass surgery [PDF]
Objectives: In addition to blood-sparing effects, aprotinin may have cardioprotective and anti-inflammatory effects during cardiopulmonary bypass-assisted cardiac surgery.

Potentiating Cerebral Perfusion Normalizes Glymphatic Dynamics in Systemic Inflammation
LPS‐induced systemic inflammation increases glymphatic influx but delays cervical lymphatic drainage, accompanied by AQP4 depolarization and impaired glymphatic clearance. Enhancing cerebral blood flow via the inotropic agent levosimendan effectively restored AQP4 polarization, improving glymphatic flux and amyloid‐β clearance.

Generation and Characterization of a Tissue-Specific Centrosome Indicator Mouse Line. [PDF]
Centrosomes are major microtubule organizing centers (MTOCs) that play an important role in chromosome segregation during cell division. Centrosomes provide a stable anchor for microtubules, constituting the centers of the spindle poles in mitotic cells,

Binding of Doxorubicin to ALYREF disrupts its phase‐separated condensate and induces DNA damage and apoptosis in cardiomyocytes Abstract The clinical utility of the anticancer agent doxorubicin (DOX) is limited by its dose‐dependent cardiotoxicity.

Depletion of Branched-Chain Aminotransferase 2 (BCAT2) Enzyme Impairs Myoblast 3 Survival and Myotube Formation [PDF]
Much is known about the positive effects of branched-chain amino acids (BCAA) in regulating muscle protein metabolism. Comparatively much less is known about the effects of these amino acids and their metabolites in regulating myotube formation.

Mechanisms of exercise-induced improvements in the contractile apparatus of the mammalian myocardium [PDF]
One of the main outcomes of aerobic endurance exercise training is the improved maximal oxygen uptake, and this is pivotal to the improved work capacity that follows the exercise training.

In contrast to the adult mammalian heart, which lacks regenerative capacity, the neonatal heart retains a transient regenerative capacity. In this study, high mobility group box 2 (HMGB2) is identified as a crucial protein driving heart regeneration based on comprehensive analyses using quantitative proteomics with tandem mass tag (TMT) labelling, RNA ...
