Frontiers in PhysiologyBlood flow restriction applied during low-load resistance training (LL-BFR) induces a similar increase in the cross-sectional area of muscle fibers (fCSA) compared to traditional high-load resistance training (HL-RT).

Nature Communications, 2021 Mitochondria produce high amounts of ATP to power myosin motors and sustained muscle contraction. Here, the authors show that during development, muscles coordinate the morphogenesis of their myofibrils directly with their mitochondria to optimize both ...

ESC Heart Failure, Volume 12, Issue 2, Page 1256-1270, April 2025.Abstract Background and aims The heart is a metabolic organ rich in mitochondria. The failing heart reprograms to utilize different energy substrates, which increase its oxygen consumption. These adaptive changes contribute to increased oxidative stress.

Stem Cells International, 2015 Quantitative methods were established to determine the level of maturation of human embryonic stem cell-derived ventricular cardiomyocytes (hESC-vCMs) that were treated with different metabolic stimulants (i.e., isoproterenol and oleic acid) during early

Theoretical considerations on myofibril stiffness
Biophysical Journal, 1997 A discrete model of the interaction between individual myofilaments was developed to study the stiffness of a sarcomere for the case in which filament compliance is not negligible. Our model retains, in the limit, the characteristics of the previously published model by Ford et al. (Ford, L. E., A. F. Huxley, and R. M. Simmons. 1981.

Dapagliflozin alleviates high‐fat‐induced obesity cardiomyopathy by inhibiting ferroptosis
ESC Heart Failure, Volume 12, Issue 2, Page 1358-1373, April 2025.Abstract Aim: Dapagliflozin (Dapa) is a novel hypoglycaemic agent with multiple cardiovascular protective effects, and it is widely used in treatment of heart failure patients, but whether it can improve obese phenotype of heart failure and its mechanism is still unclear.

Journal of Applied Toxicology, EarlyView.ABSTRACT One of the most serious complications associated with the use of the chemotherapeutic agent doxorubicin (DOX) is cardiomyopathy. Although cardioprotective drugs such as angiotensin receptor‐neprilysin inhibitors (ARNI) are used to prevent cardiomyopathy in DOX patients, no studies have reported the relationship between ARNI and endoplasmic ...

Kinetic mechanism of myofibril ATPase
Biophysical Journal, 1994 The kinetic mechanism of myofibril ATPase was investigated using psoas and mixed back muscle over a range of ionic strengths. Myofibrils were labeled with pyrene iodoacetamide to measure the rate constants for the binding of ATP and formation of the weakly attached state.

Bronchial Mucosal Abnormalities in Idiopathic Subglottic Stenosis
The Laryngoscope, EarlyView.Idiopathic subglottic stenosis (iSGS) is a challenging variant of airway stenosis associated with consistent distal airway abnormalities on bronchoscopy, including pits, depressions, and striations. Despite these findings, most patients demonstrate normal or mild–moderate obstruction on spirometry.

Submillisecond rotational dynamics of spin-labeled myosin heads in myofibrils
, 1980 The rotational motion of crossbridges, formed when myosin heads bind to actin, is an essential element of most molecular models of muscle contraction.
