TRPC5 Promotes Intermittent Hypoxia-Induced Cardiomyocyte Injury Through Oxidative Stress.
Nat Sci Sleep
December 2024
Department of Cardiovasology, the Traditional Chinese Affiliated Hospital of Xinjiang Medical University, Urumqi, 830011, People's Republic of China.
Purpose: Intermittent hypoxia (IH), a defining feature of obstructive sleep apnea (OSA), is associated with heart damage and linked to transient receptor potential canonical channel 5 (TRPC5). Nonetheless, the function of TRPC5 in OSA-induced cardiac injury remains uncertain. For this research, we aimed to explore the role and potential mechanism of TRPC5 in cardiomyocyte injury induced by intermittent hypoxia.

Introduction: Cardiac dysfunction is a common complication of sepsis. This study aimed to elucidate the regulatory effect of DLEU1 on sepsis-induced myocardial injury.
Material And Methods: HL-1 cardiomyocytes were treated with lipopolysaccharide (LPS) to mimic sepsis-induced myocardial injury in vitro, and the mouse septic model was established through cecum ligation and perforation (CLP).
Sevoflurane attenuates hypoxia/reoxygenation-induced cardiomyocyte injury by regulating miR-4454.

December 2024
Department of Cardiovascular Medicine, Ganzhou People's Hospital, No. 16 Meiguan Avenue, Ganzhou 341000, China.
Background: Sevoflurane (Sevo) prevents hypoxia/reoxygenation (H/R)-induced cardiomyocytes injury. The expression of miR-4,454 was increased in individuals experiencing an acute myocardial infarction.
Objective: The purpose of current investigation was to delved into whether the effects of Sevo on cardiomyocytes are mediated through regulation of miR-4,454 expression.
Ciprofol Ameliorates Myocardial Ischemia/Reperfusion Injury by Inhibiting Ferroptosis Through Upregulating HIF-1α.

Department of Anesthesiology, First Affiliated Hospital of Soochow University, Suzhou, Jiangsu, People's Republic of China.
Purpose: Ciprofol is a novel intravenous anesthetic that has been increasingly used in clinical anesthesia and sedation. Studies suggested that ciprofol reduced oxidative stress and inflammatory responses to alleviate cerebral ischemia/reperfusion (I/R) injury, but whether ciprofol protects the heart against I/R injury and the mechanisms are unknown. Herein, we assessed the effects of ciprofol on ferroptosis during myocardial I/R injury.

Coronary computed tomography angiography (CCTA) is a powerful tool to rule out coronary artery disease (CAD). In the last decade, myocardial perfusion CT (CTP) technique has been developed for the evaluation of myocardial ischemia, thereby increasing positive predictive value for diagnosis of obstructive CAD. A diagnostic strategy combining CCTA and perfusion acquisitions provides both anatomical coronary evaluation and functional evaluation of the stenosis, increasing the specificity and the positive predictive value of cardiac CT.
