BACKGROUND: The noble gas helium induces pre- and postconditioning in animals and humans. Volatile anesthetics induce cardioprotection in humans undergoing coronary artery bypass graft (CABG) surgery. We hypothesized that helium induces pre- and postconditioning in CABG-patients, affecting signaling molecules protein kinase C-epsilon (PKC-ε), p38 mitogen activated protein kinase (p38 MAPK), extracellular signal-regulated kinase 1/2 (ERK-1/2) and heat shock protein 27 (HSP-27) within cardiac tissue, and reducing postoperative troponin levels...

BACKGROUND: In many clinical conditions that involve free flaps and tissue transplantations the possibility of minimizing ischemia-reperfusion injury can be a determinant factor for the success of the surgery itself. We hypothesize that preconditioning with sevoflurane is a protective factor against ischemia-reperfusion injury. METHODS: In this randomized controlled trial, patients ASA I-II undergoing breast reconstruction with deep inferior epigastric perforator flaps were allocated into two groups and analyzed: group BAL included patients who received balanced anesthesia with sevoflurane for 30 min before removal of the flap and throughout the surgery...

PURPOSE: Sevoflurane preconditioning (SevoPreC) has been proved to prevent organ ischemia/reperfusion (I/R) injury in various animal models and preclinical studies. Clinical trials on cardioprotection by SevoPreC for adult patients undergoing coronary artery bypass graft (CABG) revealed mixed results. The aim of this meta-analysis was to evaluate the cardiac effect of SevoPreC in on-pump CABG. METHODS: Randomized controlled trials (RCT) comparing the cardiac effect of SevoPreC (compared with control) in adult patients undergoing CABG were searched from PubMed, Embase, and the Cochrane Library (up to November 2015)...

PURPOSE: The glycocalyx is a glycoprotein-polysaccaride layer covering the endothelium luminal surface, and plays a key regulatory role in several endothelial functions. Lung ischemia reperfusion (IR) is a clinical entity that occurs in everyday thoracic surgery and causes glycocalix destruction and a florid local and systemic immune response. Moreover, sevoflurane is able to modulate the inflammatory response triggered by IR lung injury. In this study, we evaluated the protective effects of sevoflurane on the pulmonary endothelial glycocalyx in an in-vivo lung autotransplant model in pigs...

Sevoflurane has been shown to improve ischemia/reperfusion injury (IRI) through several mechanisms, including amelioration of inflammatory response. However, there haven't been any studies considering the potential role of the complement system in sevoflurane-mediated amelioration of ischemia/reperfusion injury. Our purpose was to investigate the molecular mechanisms involved in sevoflurane preconditioning in liver and lung injury induced by liver ischemia-reperfusion (LIR), giving emphasis to the immunological mechanisms...

BACKGROUND: Tumor cell migration and diffuse infiltration into brain parenchyma are known causes of recurrence after treatment in glioblastoma (GBM), mediated in part by the interaction of glioma cells with the extracellular matrix, followed by degradation of matrix by tumor cell derived proteases, particularly the matrix metalloproteinases (MMP). Sevoflurane and thiopental are anesthetics commonly used in cancer surgery. However, their effect on the progression of glioma cells remains unclear...

BACKGROUND: Reverse-mode of the Na(+)/Ca(2+) exchanger (NCX) stimulation provides cardioprotective effects for the ischemic/reperfused heart during ischemic preconditioning (IP). This study was designed to test the hypothesis that pretreatment with an inhibitor of cardiac delayed-rectifying K(+) channel (IKr), E4031, increases reverse-mode of NCX activity, and triggers preconditioning against infarct size (IS) and arrhythmias caused by ischemia/reperfusion injury through mitoKCa channels...

Acute lung injury (ALI) mainly occurs as increased permeability of lung tissue and pleural effusion. Inhaled anesthetic sevoflurane has been demonstrated to alleviate lung permeability by upregulating junction proteins after ischemia-reperfusion. However, the exact mechanisms of its protective effect on reperfusion injury remain elusive. The aim of this study was to assess possible preconditioning with sevoflurane in an in vitro model of lipopolysaccharide (LPS)-induced barrier dysfunction in human lung microvascular endothelial cells (HMVEC-Ls)...

Ischemic preconditioning (IPC) has been considered to be a potential therapy to reduce ischemia-reperfusion injury (IRI) since the 1980s. Our previous study indicated that sevoflurane preconditioning (SPC) also reduced intestinal IRI in rats. However, whether the protective effect of SPC is similar to IPC and the mechanisms of SPC are unclear. Thus, we compared the efficacy of SPC and IPC against intestinal IRI and the role of protein kinase C (PKC) and mitochondrial ATP-sensitive potassium channel (mKATP) in SPC...

Neuroprotection against cerebral ischemia afforded by volatile anesthetic preconditioning (APC) has been demonstrated both in vivo and in vitro, yet the underlying mechanism is poorly understood. We previously reported that repeated sevoflurane APC reduced infarct size in rats after focal ischemia. In this study, we investigated whether inhibition of apoptotic signaling cascades contributes to sevoflurane APC-induced neuroprotection. Male Sprague-Dawley rats were exposed to ambient air or 2.4 % sevoflurane for 30 min per day for 4 consecutive days and then subjected to occlusion of the middle cerebral artery (MCAO) for 60 min at 24 h after the last sevoflurane intervention...

BACKGROUND: Sevoflurane is one of the commonly used volatile anesthetics in cancer patients. The protective effect of sevoflurane preconditioning has raised concerns about whether sevoflurane could act advantageously for survival even of cancer cells. Therefore, we investigated the effects of sevoflurane on proliferation in colon cancer cell lines. METHODS: HCT116 and HT29 cells were plated in 96-well plates at a density of 1 x 10(4) cells/well and incubated overnight...

BACKGROUND: Sevoflurane preconditioning (SP) has been shown to invoke potent myocardial protection in animal studies and clinical trials. However, the mechanisms underlying SP are complex and not yet well understood. We investigated the hypothesis that the cardioprotection afforded by SP is mediated via the Wnt/glycogen synthase kinase 3β (GSK3β)/β-catenin signaling pathway. METHODS: Two models were established: a Langendorff perfused rat heart model and the H9C2 cell hypoxia/reoxygenation model...

The mechanism of sevoflurane preconditioning-induced neuroprotection is poorly understood. This study was aimed at identifying microRNAs (miRNAs) involved in the protective effect of sevoflurane preconditioning against hypoxic injury using the miRCURYTM LNA Array. The screened differentially expressed miRNAs were further validated using qRT-PCR. Finally, after transfection of miRNA (miR-101a or miR-34b) mimics or inhibitor, MTT and flow cytometry assays were used to evaluate cell survival and apoptosis in sevoflurane preconditioning...
