Aim: The objective of the present study was to evaluate the protective effects of halofuginone against renal ischemia/reperfusion (I/R) injury.
Materials And Methods: Male Wistar albino rats were unilaterally nephrectomized and the left renal pedicles were occluded for 45 min to induce ischemia and then reperfused for 6 h (early) or for 72 h (late). The rats were treated intraperitoneally with either halofuginone (100 μg/kg/day) or saline 30 min prior to ischemia and the dose was repeated in the late reperfusion groups. In the sham groups, rats underwent unilateral nephrectomy and were treated at similar time points. The animals were decapitated at either 6 h or 72 h of reperfusion and trunk blood and kidney samples were obtained.
Results: I/R injury increased renal malondialdehyde levels, myeloperoxidase activity and reactive oxygen radical levels, and decreased the renal glutathione content. Halofuginone treatment was found to reduce oxidative I/R injury and improve renal function in the rat kidney, as evidenced by reduced generation of reactive oxygen species, depressed lipid peroxidation and myeloperoxidase activity, and increased glutathione levels.
Conclusions: The present findings demonstrate the anti-inflammatory and antioxidant effects of halofuginone in renal I/R injury, supporting its potential use where renal I/R injury is inevitable.

Bufalin, which is isolated from toad venom, exerts positive effects on hearts under pathological circumstance. We aimed to investigate the effects and mechanisms of bufalin on myocardial I/R injury. In vivo, bufalin ameliorated myocardial I/R injury, which characteristics with better ejection function, decreased infarct size and less apoptosis.

Despite improvements in interventional techniques leading to faster myocardial reperfusion postmyocardial infarction, there has been a significant rise in the occurrence of myocardial ischaemia/reperfusion injury (MI/RI). A deeper understanding of the underlying mechanisms of MI/RI could offer a crucial approach to reducing myocardial damage and enhancing patient outcomes. This study examined the myocardial protective properties of puerarin (PUE) in the context of MI/RI using hypoxia/reoxygenation (H/R) or ischaemia/reperfusion (I/R) injury models were employed in H9c2 cells and C57BL/6 mice.

Background: We sought to define whether and how hepatic ischemia/reperfusion (I/R) as manifested by perioperative aspartate aminotransferase (AST) and alanine aminotransaminase (ALT) levels impact long-term outcomes after curative-intent resection of hepatocellular carcinoma (HCC).
Patients And Methods: Intrasplenic injection of HCC cells was used to establish a murine model of HCC recurrence with versus without I/R injury. Patients who underwent curative resection for HCC were identified from a multi-institutional derivative cohort (DC) and separate external validation (VC) cohort.

Nuclear factor erythroid 2-related factor 2 (NRF2) is a redox-sensitive transcriptional factor that enables cells to resist oxidant responses, ferroptosis and inflammation. Here, we set out to probe the effects of NRF2 on cardiomyocyte injury under acute myocardial infarction (AMI) condition and its potential mechanism. Human cardiomyocytes were exposed to hypoxia/reoxygenation (H/R) to induce cell injury.

Introduction: Ischemia followed by reperfusion in organ transplantations can lead to ischemia-reperfusion (I-R) injury, which is associated with oxidative stress and inflammatory responses. Alpha-pinene is an organic terpene with well-known antioxidant, anti-inflammatory, and anti-apoptotic properties. This study examines the preventive effects of alpha-pinene against renal I-R-induced kidney dysfunction, oxidative and inflammatory status, apoptosis, and histopathology changes.
