Recent studies have uncovered the vital roles played by microRNAs (miRNAs) in regulating cardiac injury. Amongst them, the cardiac enriched microRNA-1 (miR-1) has been extensively studied and proven to be detrimental to cardiac myocytes. Hence, the current study aims to explore whether miR-1 affects myocardial ischemia/reperfusion injury (MIRI) in rats undergoing sevoflurane preconditioning and the underlying mechanism. After successful model establishment, rats with MIRI were transfected with mimics or inhibitors of miR-1, or siRNA against MAPK3, and then were injected with sevoflurane...

Purpose: Sevoflurane preconditioning (SPC) can provide myocardial protective effects similar to ischemic preconditioning. However, the exact mechanism of SPC remains unclear. Previous studies indicate that vascular endothelial growth factor receptor 1 (VEGFR-1) is involved in ischemic preconditioning-mediated cardioprotection. This study was designed to determine the significance of VEGFR-1 signaling in SPC-mediated cardioprotection. Materials and methods: Myocardial ischemia-reperfusion (I/R) rat model was established using the Langendorff isolated heart perfusion apparatus...

Volatile anesthetic preconditioning has been shown to be a potent way to provide myocardium protection against ischemia/reperfusion (I/R) injury; however, this cardioprotection is lost in senescent animal models and elderly patients. NFkB-regulated genes have been linked to myocardial I/R injury and anesthetic preconditioning. Here, we investigated NFkB activation related to anesthetic preconditioning in aging rat myocardium. Isolated, Langendorff perfused rat hearts from Fischer 344 male rats, 24 months old, were randomly assigned to one of the three groups...

Anesthetic preconditioning is a cellular protective approach whereby exposure to a volatile anesthetic renders cardio injury. Sevoflurane preconditioning has been shown to exhibit cardio protective effect on hypoxia/reoxygenation (H/R) injury, but the underlying mechanism is unclear. Syntaxin 1A (STX1A), an important regulator in cardio disease, was predicted to be the target gene of microRNA-34a-5p (miR-34a-5p). The current research was designed to delineate the role of miR-34a-5p in regulating sevoflurane preconditioning in cardiomyocytes injury...

Systemic inflammation induces brain neuronal inflammation, in turn causing acute cognitive disorders. Furthermore, neuronal inflammation is one cause of postoperative cognitive disorder (POCD) and delirium. However, no sufficiently established pharmacological treatment is available for neurocognitive inflammation. This study evaluated the possible neuroprotective effects of preconditioning with sevoflurane anesthesia on cognition and neuroinflammatory changes in an animal model of lipopolysaccharide (LPS)-induced systemic inflammation...

Acute traumatic spinal cord injury (tSCI) results in a lifetime of paralysis associated with a host of medical complications. The developing secondary complications of tSCI may result in further chronic neurodegenerative diseases. Sevoflurane preconditioning (SF-PreCon) has shown guaranteed protective effects in myocardial or cerebral ischemic/reperfusion injury. However, the role of SF-PreCon in tSCI still remains to be elucidated. Here, we found that SF-PreCon ameliorated the developing secondary complications through reducing the apoptosis rate and the secretion of inflammatory cytokines in injured spinal cord tissues, and therefore enhancing the recovery after tSCI...

BACKGROUND: Various volatile anesthetics and ischemic preconditioning (IP) have been demonstrated to exert protective effect against ischemia/reperfusion (I/R) injury in liver. We aimed to determine whether application of IP under isoflurane and sevoflurane anesthesia would confer protection against hepatic I/R injury in rats. METHODS: Thirty-eight rats weighing 270 to 300 grams were randomly divided into 2 groups: isoflurane (1.5%) and sevoflurane (2.5%) anesthesia groups...

Remote ischemic preconditioning (RIPC) seems to be a promising cardioprotective strategy with contradictive clinical data suggesting the anesthetic regimen influencing the favorable impact of RIPC. This study aimed to investigate whether cardio protection by RIPC is abolished by anesthetic regimens. Male Wistar rats were randomized to 6 groups. Anesthesia was either maintained by pentobarbital (Pento) alone or a combination of sevoflurane (Sevo) and remifentanil or propofol (Prop) and remifentanil in combination with and without RIPC...

Severe trauma constitutes a major cause of death and disability, especially in younger patients. The cerebral autoregulatory capacity only protects the brain to a certain extent in states of hypovolemia; thereafter, neurological deficits and apoptosis occurs. We therefore set out to investigate neuroprotective strategies during haemorrhagic shock. This review was performed in accordance to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Before the start of the search, a review protocol was entered into the PROSPERO database...

BACKGROUND: Efficacy of remote ischemic preconditioning (RIPC) for cardioprotection in cardiac surgery is controversial. We aimed to evaluate the clinical and molecular effects of RIPC on the concentrically hypertrophied myocardium. METHODS: Seventy-two aortic stenosis patients receiving aortic valve replacement (AVR) under sevoflurane anesthesia were randomly allocated to RIPC (3cycles of 5-min inflation [300mmHg] and deflation on the left arm) or control (deflated cuff placement) group...

Background: Calcium regulatory proteins-L-type Ca2+ channels (LTCCs), ryanodine receptor 2 (RyR2), and Na+ /Ca2+ exchanger isoform 1 (NCX1) have been recognized as important protective mechanisms during myocardial ischemia-reperfusion injury (I/RI). Both sevoflurane postconditioning (SevoPoC) and delayed remote ischemic preconditioning (DRIPC) have been shown to protect the heart against I/RI. In this study, we aimed to compare the effects of SevoPoC and DRIPC on the expression of the three calcium regulatory proteins in an isolated rat heart model...

BACKGROUND: Myocardial ischaemia reperfusion injury following cardiac surgery with cardiopulmonary bypass (CPB) increases postoperative mortality. Setting techniques to protect the heart during this critical period therefore represents a considerable challenge. METHOD: A randomised controlled study in Caen University Hospital Centre, investigated whether the clinical cardio protective effects of administration sevoflurane before cardiopulmonary bypass during coronary artery bypass graft surgery (CABG) could translate into protected atrial trabeculae contractility against hypoxia-reoxygenation in vitro...

Late preconditioning (LPC) can be induced by volatile anesthetics and initiates cardioprotection against ischemia/reperfusion injury for three to four days. We investigated the possibility to extend the time window of sevoflurane-induced LPC by repeated sevoflurane administration. An in vivo rat model of regional myocardial ischemia/reperfusion injury was used. Myocardial infarct size was determined by TTC staining at the end of the experiment. In the first series of experiments, male Wistar rats were randomized to five groups (each n=8)...

BACKGROUND: Although sevoflurane (Sevo) had been shown to ameliorate posttransplant injury in various organs, data available are inconsistent, particularly in the context of lung transplantation (Tx). We here investigated if preconditioning by Sevo can protect from posttransplant injury regarding both, primary graft dysfunction (PGD) and acute rejection (AR) after experimental lung Tx, thereby focusing on two important clinical outcome parameters. MATERIALS AND METHODS: Three experimental approaches were used: (1) BALB/c mice were preconditioned for 2 h with Sevo or a fentanyl cocktail (Control; n = 10); (2) syngeneic (Syn) mouse lung Tx (C57BL/6) with a Sevo-preconditioned graft followed by 18 h storage to mimic PGD (Syn-Tx, n = 12) versus controls (fentanyl cocktail); and (3) allogeneic (Allo) Tx (BALB/c, donor; C57BL/6, recipient) to mimic AR (Allo-Tx, n = 12) versus controls (fentanyl cocktail)...

BACKGROUND: Sevoflurane postconditioning (S-post) has similar cardioprotective effects as ischemic preconditioning. However, the underlying mechanism of S-post has not been fully elucidated. Janus kinase signaling transduction/transcription activator (JAK2-STAT3) plays an important role in cardioprotection. The purpose of this study was to determine whether the cardioprotective effects of S-post are associated with activation of the JAK2-STAT3 signal pathway. METHODS: An adult male Sprague-Dawley (SD) rat model of myocardial ischemia/reperfusion (I/R) injury was established using the Langendorff isolated heart perfusion apparatus...
