Metabolic abnormalities and reprogramming in cats with naturally occurring hypertrophic cardiomyopathy

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.

New insights provided by myofibril mechanics in inherited cardiomyopathies [PDF]

, 2019
Cardiomyopathies represent a heterogeneous group of cardiac disorders that perturb cardiac contraction and/or relaxation, and can result in arrhythmias, heart failure, and sudden cardiac death.

Hysteresis cycles of a single myofibril. [PDF]

, 2016
A A single myofibril consisting of 7 sarcomeres was stretched to an averaged sarcomere length of 3.7μm and subsequently cycled by approximately ± 2.5μm. The small insert shows the corresponding average sarcomere length (red line) ± standard error (black ...

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.

Myofibril diameter is set by a finely tuned mechanism of protein oligomerization in Drosophila

eLife, 2019
Myofibrils are huge cytoskeletal assemblies embedded in the cytosol of muscle cells. They consist of arrays of sarcomeres, the smallest contractile unit of muscles.

The Effects of Angiotensin Receptor Neprilysin Inhibitor on Endoplasmic Reticulum Stress in Doxorubicin‐Mediated Cardiomyopathy‐Associated Heart Failure Model in Rats

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 ...

Effect of Sarcoplasmic Protein Solutions Dried at Different Times and Rates on Water Migration in Lamb Myofibril In Vitro

Foods
To determine whether sarcoplasmic proteins affected water migration in myofibrils during air-drying, with protein denaturation as an indicator of sarcoplasmic protein changes, the extent of sarcoplasmic protein changes in lamb during air-drying was first

Polyphenol dietary supplementation prevents inflammation‐induced muscle atrophy in a zebrafish (Danio rerio) model

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Diet‐induced inflammation is a major cause of muscle degeneration impacting human and animal health. Owing to their anti‐inflammatory and antioxidant properties, polyphenols have attracted considerable interest as feed additives.

INTRINSIC BIREFRINGENCE OF GLYCERINATED MYOFIBRILS [PDF]

The Journal of Cell Biology, 1971
Patterns of intrinsic birefringence were revealed in formalin-fixed, glycerinated myofibrils from rabbit striated muscle, by perfusing them with solvents of refractive index near to that of protein, about 1.570. The patterns differ substantially from those obtained in physiological salt solutions, due to the elimination of edge- and form birefringence.
