Aims: We sought to review cellular changes that occur with reperfusion to try to understand whether ischemia-reperfusion injury (RI) is a potentially modifiable therapeutic target for cardioprotection or neuroprotection in patients undergoing cardiopulmonary resuscitation.
Data Sources: Articles written in English and published in PubMed.
Results: Remote ischemic conditioning (RIC) involves brief episodes of non-lethal ischemia and reperfusion applied to an organ or limb distal to the heart and brain. Induction of hypothermia involves cooling an ischemic organ or body. Both have pluripotent effects that reduce the potential harm associated with RI in the heart and brain by reduced opening of the mitochondrial permeability transition pore. Recent trials of RIC and induced hypothermia did not demonstrate these treatments to be effective. Assessment of the effect of these interventions in humans to date may have been modified by use of concurrent medications including propofol.
Conclusions: Ongoing research is necessary to assess whether reduction of RI improves patient outcomes.

Intestinal ischemia-reperfusion injury (IIR/I) significantly increases morbidity and mortality. This study examines the therapeutic effects of geraniol (GNL), which is noted for its anti-inflammatory and antioxidant properties, on intestinal I/R injury in rats. Forty-nine male Wistar-Albino rats were divided into seven groups.

Precise and effective management of myocardial ischemia/reperfusion injury (MIRI) is still a formidable challenge in clinical practice. Additionally, real-time monitoring of drug aggregation in the MIRI region remains an open question. Herein, a drug delivery system, hesperadin and ICG assembled in PLGA-Se-Se-PEG-IMTP (HI@PSeP-IMTP), is designed to deliver hesperadin and ICG to the MIRI region for in vivo optical imaging tracking and to ameliorate MIRI.

Background: Therapeutic hypothermia improves outcomes in experimental stroke models, especially after ischemia-reperfusion injury. In recent years, the safety and efficacy of hypothermia combining thrombolysis or mechanical thrombectomy have attracted widespread attention. The primary objective of the study was to evaluate the effectiveness and safety of hypothermia by combining reperfusion therapy in acute ischemic stroke patients.

Acute kidney injury induced by stings from multiple wasps is a medical emergency and is a driving factor of acute renal dysfunction. Numerous studies have shown that mitochondrial reactive oxygen species (mtROS) play a key role in ischemia-reperfusion injury-, cisplatin-, and sepsis-induced acute kidney injury. However, the role of mtROS and its underlying mechanisms in wasp-venom-induced acute kidney injury remain inconclusive.

Introduction: Grafts with alcohol-associated liver disease (ALD) subjected to prolonged cold ischaemia from donors after brain death (DBD) are typically unsuitable for transplantation. Here, we investigated the role of growth hormone (GH) in livers with ALD from DBDs and its relationship with vascular endothelial growth factor A (VEGFA) and VEGFB.
Methods: Livers from rats fed ethanol for 6 weeks and with brain death (BD) were cold stored for 24 h and subjected to reperfusion.
