Abstract
Acute myocardial infarction (AMI) is associated with high morbidity and mortality worldwide. Although early reperfusion is the most effective strategy to salvage ischemic myocardium, reperfusion injury can develop with the restoration of blood flow. Therefore, it is important to identify protection mechanisms and strategies for the heart after myocardial infarction. Recent studies have shown that multiple intracellular molecules and signaling pathways are involved in cardioprotection. Meanwhile, device-based cardioprotective modalities such as cardiac left ventricular unloading, hypothermia, coronary sinus intervention, supersaturated oxygen (SSO2), and remote ischemic conditioning (RIC) have become important areas of research. Herein, we review the molecular mechanisms of cardioprotection and cardioprotective modalities after ischemia-reperfusion injury (IRI) to identify potential approaches to reduce mortality and improve prognosis in patients with AMI.

Pathways for Cardioprotection in Perspective: Focus on Remote Conditioning and Extracellular Vesicles. BIOLOGY 2023; 12:biology12020308.

Abstract
Despite the development of cutting-edge treatments, coronary artery disease (CAD) morbidity and mortality rates remain present at high levels. Therefore, new cardioprotective approaches are crucial to improve the health of patients. To date, experimental investigations of acute ischemia-reperfusion injury (IRI) have generally demonstrated the efficacy of local ischemic preconditioning and postconditioning cardioprotection techniques as well as of remote conditioning. However, application in clinical settings is still highly controversial and debated. Currently, remote ischemic conditioning (RIC) seems to be the most promising method for heart repair. Protective factors are released into the bloodstream, and protection can be transferred within and across species. For a long time, the cross-function and cross-transmission mechanisms of cardioprotection were largely unknown. Recently, it has been shown that small, anuclear, bilayered lipid membrane particles, known as extracellular vesicles (EVs), are the drivers of signal transduction in cardiac IRI and RIC. EVs are related to the pathophysiological processes of cardiovascular diseases (CVDs), according to compelling evidence. In this review, we will first review the current state of knowledge on myocardial IRI and cardioprotective strategies explored over the past 37 years. Second, we will briefly discuss the role of EVs in CVD and the most recent improvements on EVs as prognostic biomarkers, diagnostic, and therapeutic agents. We will discuss how EVs can be used as a new drug delivery mechanism and how they can be employed in cardiac treatment, also from a perspective of overcoming the impasse that results from neglecting confounding factors.

Abstract
INTRODUCTION Upon injury, skeletal muscle undergoes a multiphase process beginning with degeneration of the damaged tissue, which is accompanied by inflammation and finally regeneration. One consequence of an injured microenvironment is excessive production of reactive oxygen species, which results in attenuated regeneration and recovery of function ultimately leading to fibrosis and disability. The objective of this research was to test the potential of the antioxidant, N-Acetyl-L-Cysteine (NAC), as a mediator of reactive oxygen species damage that results from traumatic muscle injury in order to support repair and regeneration of wounded muscle tissue and improve function recovery. MATERIALS AND METHODS Adult female Lewis rats were subjected to compartment syndrome injury as previously published by our group. Rats received intramuscular injections of NAC or vehicle at 24, 48, and 72 hours postinjury. Muscle function, tissue fibrosis, and the expression of myogenic and angiogenic markers were measured. RESULTS Muscle function was significantly improved, and tissue fibrosis was significantly decreased in NAC-treated muscles. CONCLUSIONS These results suggest that NAC treatment of skeletal muscle after injury may be a viable option for the prevention of long-term fibrosis and scar formation, facilitating recovery of muscle function.

Abstract
BACKGROUND The role of the neurogenic pathway in early phases of cardioprotection during remote ischemic preconditioning (RIPC) and adenosine preconditioning is reported. AIM This study was designed to explore the involvement of the neurogenic pathway in late phases of cardioprotection during RIPC and adenosine preconditioning. MATERIAL AND METHODS Fifty-four Wistar rats were used and divided into 9 experimental groups. RIPC was induced by tying the blood pressure cuff around the hind limb and subjecting to 4 cycles of inflation and deflation of 5 minutes each. In early RIPC, the heart was isolated immediately after the last episode of RIPC, whereas in late RIPC, the heart was isolated 24 hours after the last cycle of RIPC. In a similar way, adenosine preconditioning was instituted in early and late phases by either isolating the heart 40 minutes or 24 hours after adenosine (4 mg/kg, intraperitoneally [i.p.]) administration. Isolated hearts were subjected to ischemia-reperfusion (I/R) injury on the Langendorff's system. RESULTS Both early and late phases of RIPC and adenosine preconditioning significantly abrogated I/R-induced myocardial injury in terms of decrease in the release of lactate dehydrogenase, creatine kinase, and decrease in infarct size. Pretreatment with hexamethonium, a ganglion blocker (20 mg/kg, i.p.), significantly abolished the cardioprotective effects of both early and late phases of RIPC and adenosine preconditioning. CONCLUSION Apart from the involvement of the neurogenic pathway in the early phases, there is a critical role of the neurogenic pathway in the late phase of cardioprotection during RIPC and adenosine preconditioning.

Abstract
A humoral mechanism of cardioprotection by remote ischemic preconditioning (RIP) has been clearly demonstrated in various models of ischemia-reperfusion including upper and lower extremities, liver, and the mesenteric and renal arteries. A wide range of humoral factors for RIP have been proposed including hydrophobic peptides, opioid peptides, adenosine, prostanoids, endovanilloids, endocannabinoids, calcitonin gene-related peptide, leukotrienes, noradrenaline, adrenomedullin, erythropoietin, apolipoprotein, A-I glucagon-like peptide-1, interleukin 10, stromal cell-derived factor 1, and microRNAs. Virtually, all of the components of ischemic preconditioning's signaling pathway such as nitric oxide synthase, protein kinase C, redox signaling, PI3-kinase/Akt, glycogen synthase kinase β, ERK1/2, mitoKATP channels, Connexin 43, and STAT were all found to play a role. The signaling pattern also depends on which remote vascular bed was subjected to ischemia and on the time between applying the rip and myocardial ischemia occurs. Because there is convincing evidence for many seemingly diverse humoral components in RIP, the most likely explanation is that the overall mechanism is complex like that seen in ischemic preconditioning where multiple components are both in series and in parallel and interact with each other. Inhibition of any single component in the right circumstance may block the resulting protective effect, and selectively activating that component may trigger the protection. Identifying the humoral factors responsible for RIP might be useful in developing drugs that confer RIP's protection in a more comfortable and reliable manner.

Abstract
The heart must consume a significant amount of energy to sustain its contractile activity. Although the fuel demands are huge, the stock remains very low. Thus, in order to supply its daily needs, the heart must have amazing adaptive abilities, which are dependent on dioxygen availability. However, in myriad cardiovascular diseases, “fuel” depletion and hypoxia are common features, leading cardiomyocytes to favor low-dioxygen-consuming glycolysis rather than oxidation of fatty acids. This metabolic switch makes it challenging to distinguish causes from consequences in cardiac pathologies. Finally, despite the progress achieved in the past few decades, medical treatments have not improved substantially, either. In such a situation, it seems clear that much remains to be learned about cardiac diseases. Therefore, in this review, we will discuss how reconciling dioxygen availability and cardiac metabolic adaptations may contribute to develop full and innovative strategies from bench to bedside.

Abstract
A 2×2 factorial design was used to evaluate possible preservation of mitochondrial functions in two cardioprotective experimental models, remote ischemic preconditioning and streptozotocin-induced diabetes mellitus, and their interaction during ischemia/reperfusion injury (I/R) of the heart. Male Wistar rats were randomly allocated into four groups: control (C), streptozotocin-induced diabetic (DM), preconditioned (RPC) and preconditioned streptozotocin-induced diabetic (DM+RPC). RPC was conducted by 3 cycles of 5-min hind-limb ischemia and 5-min reperfusion. DM was induced by a single dose of 65 mg/kg streptozotocin. Isolated hearts were exposed to ischemia/reperfusion test according to Langendorff. Thereafter mitochondria were isolated and the mitochondrial respiration was measured. Additionally, the ATP synthase activity measurements on the same preparations were done. Animals of all groups subjected to I/R exhibited a decreased state 3 respiration with the least change noted in DM+RPC group associated with no significant changes in state 2 respiration. In RPC, DM and DM+RPC group, no significant changes in the activity of ATP synthase were observed after I/R injury. These results suggest that the endogenous protective mechanisms of RPC and DM do preserve the mitochondrial function in heart when they act in combination.

Remote Ischemic Preconditioning Enhances the Expression of Genes Encoding Antioxidant Enzymes and Endoplasmic Reticulum Stress-Related Proteins in Rat Skeletal Muscle.

Abstract
Purpose: Ischemic preconditioning (IPC), including remote IPC (rIPC) and direct IPC (dIPC), is a promising method to decrease ischemia-reperfusion (IR) injury. This study tested the effect of both rIPC and dIPC on the genes for antioxidant enzymes and endoplasmic reticulum (ER) stress-related proteins. Materials and Methods: Twenty rats were randomly divided into the control and study groups. In the control group (n=10), the right hind limb was sham-operated. The left hind limb (IscR) of the control group underwent IR injury without IPC. In the study group (n=10), the right hind limb received IR injury after 3 cycles of rIPC. The IscR received IR injury after 3 cycles of dIPC. Gene expression was analyzed by Quantitative real-time polymerase chain reaction from the anterior tibialis muscle. Results: The expression of the antioxidant enzyme genes including glutathione peroxidase (GPx), superoxide dismutase (SOD) 1 and catalase (CAT) were significantly reduced in IscR compared with sham treatment. In comparison with IscR, rIPC enhanced the expression of GPx, SOD2, and CAT genes. dIPC enhanced the expression of SOD2 and CAT genes. The expression of SOD2 genes was consistently higher in rIPC than in dIPC, but the difference was only significant for SOD2. The expression of genes for ER stress-related proteins tended to be reduced in IscR in comparison with sham treatment. However, the difference was only significant for C/EBP homologous protein (CHOP). In comparison with IscR, rIPC significantly up-regulated activating transcription factor 4 and CHOP, whereas dIPC up-regulated CHOP. Conclusion: Both rIPC and dIPC enhanced expression of genes for antioxidant enzymes and ER stress-related proteins.

Abstract
The aim of this study was to estimate the protective effect of N-acetyl-l-cysteine (NAC) against cisplatin-induced cardiotoxicity under conditions of ischemic-reperfusion injury. Wistar albino rats were randomly divided into three groups (n = 8): control, cisplatin (5 mg/kg/w, i.p., 5 weeks) and cisplatin + NAC group (cisplatin – 5 mg/kg/w, i.p. and NAC – 500 mg/kg/w, i.p., 5 weeks). Isolated hearts were perfused according to the modified Langendorff technique at constant pressure (70 cmH2O). Following cardiodynamic parameters were measured: maximum rate of left ventricular pressure development, minimum rate of left ventricular pressure development, left ventricular systolic pressure (SLVP), left ventricular diastolic pressure and heart rate. The ischemic vasodilation episodes were induced by the complete interruption of coronary inflow for 30, 60 and 120 s. The samples of the coronary venous effluent (CVE) were continuously collected during the reperfusion period for determination of coronary flow (CF) rate and oxidative stress markers (H2O2, O2−, NO2− and thiobarbituric acid reactive substances – TBARS). Cisplatin reduced CF, heart rate and overflow (total, maximal and duration of overflow) during reperfusion, and increased SLVP (under basal conditions and after global ischemias). Cisplatin increased levels of H2O2 (under basal conditions), O2− and TBARS (under basal conditions and after ischemia), but decreased NO2− levels (during reperfusion) in CVE, and decreased superoxide dismutase and reduced glutathione in serum. NAC attenuated cisplatin-induced changes of cardiodynamic parameters (except CF under basal conditions) and oxidative stress parameters. Those results suggest that NAC, by decreasing oxidative stress, may be useful in cardioprotection during cisplatin therapy.

Abstract
Monoamine oxidases (MAOs) have recently emerged as important mitochondrial sources of oxidative stress in the cardiovascular system. Generation of reactive oxygen species during the brief episodes of ischemic preconditioning (IPC) is responsible for the cardioprotection at reperfusion. The aim of this study was to assess the effects of two MAO inhibitors (clorgyline and pargyline) on the IPC-related protection in isolated rat hearts. Animals subjected to 30 min global ischemia and 120 min reperfusion were assigned to the following groups: (i) Control, no additional intervention; (ii) IPC, 3 cycles of 5 min ischemia and 5 min reperfusion before the index ischemia; (iii) IPC-clorgyline, IPC protocol bracketed for 5 min with clorgyline (50 μmol/L); (iv) IPC-pargyline, IPC protocol bracketed for 5 min with pargyline (0.5 mmol/L). The postischemic functional recovery was assessed by the left ventricular developed pressure (LVDP) and the indices of contractility (+dLVP/dt max) and relaxation (-dLVP/dt max). Infarct size (IS) was quantified by TTC staining. In both genders, IPC significantly improved functional recovery that was further enhanced in the presence of either clorgyline or pargyline. IS reduction was comparable among all the preconditioned groups, regardless of the presence of MAO inhibitors. In isolated rat hearts, acute inhibition of MAOs potentiates the IPC-induced postischemic functional recovery without interfering with the anti-necrotic protection.

Abstract
Background. Remote ischemic preconditioning (RIP) and pharmacological preconditioning are the effective methods that can be used to prevent ischemia reperfusion (IR) injury. The aim of this study was to evaluate the effects of RIP and N-Acetylcysteine (NAC) with RIP in the rat hepatic IR injury model. Materials and Methods. 28 rats were divided into 4 groups. Group I (sham): only laparotomy was performed. Group II (IR): following 30 minutes of hepatic pedicle occlusion, 4 hours of reperfusion was performed. Group III (RIP + IR): following 3 cycles of RIP, hepatic IR was performed. Group IV (RIP + NAC + IR): following RIP and intraperitoneal administration of NAC (150 mg/kg), hepatic IR was performed. All the rats were sacrificed after blood samples were taken for the measurements of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels and liver was processed for conventional histopathology. Results. The hepatic histopathological injury scores of RIP + IR and RIP + NAC + IR groups were significantly lower than IR group (P = 0.006, P = 0.003, resp.). There were no significant differences in AST and ALT values between the IR, RIP + IR, and RIP + NAC + IR groups. Conclusions. In the present study, it was demonstrated histopathologically that RIP and RIP + NAC decreased hepatic IR injury significantly.

Abstract
Reactive oxygen species (ROS) are hypothesized to play a key role in myocardial ischemia-reperfusion (IR) injury after cardiopulmonary bypass in children. Clinical studies in adults and several animal models suggest that myocardial IR injury involves cardiomyocyte apoptosis and necrosis. This study investigated a potential relationship between IR-induced ROS production and neonatal cardiomyocyte apoptosis using both in vitro and ex vivo techniques. For in vitro experiments, embryonic rat cardiomyocytes (H9c2 cells) exposed to hypoxia-reoxygenation (HR) showed a time-dependent increase in gp91 phox (a marker for ROS production by NADPH oxidases), caspase-3 (a key mediator of apoptosis) expression, and a decrease in the glutathione redox ratio. N-acetylcysteine (NAC; 0.25-2 mM), a potent antioxidant, decreased gp91 phox and caspase-3 expression, inhibited apoptosis and restored the glutathione redox ratio. For ex vivo study, IR injury significantly reduced left ventricular (LV) function and increased the expression of gp91 phox and caspase-3 in Langendorff-perfused neonatal (7-14 d) rabbit hearts. NAC (0.4 mM) treatment completely attenuated LV dysfunction after IR. In summary, neonatal myocardial IR injury is associated with an increase in cardiomyocyte oxidative stress and apoptosis. NAC attenuates apoptosis in an in vitro embryonic rat cardiomyocyte model of HR, and myocardial dysfunction in an ex vivo neonatal rabbit model of myocardial IR injury.

Abstract
Although cellular transplantation has been shown to promote improvements in cardiac function following injury, poor cell survival following transplantation continues to limit the efficacy of this therapy. We have previously observed that transplantation of muscle-derived stem cells (MDSCs) improves cardiac function in an acute murine model of myocardial infarction to a greater extent than myoblasts. This improved regenerative capacity of MDSCs is linked to their increased level of antioxidants such as glutathione (GSH) and superoxide dismutase. In the current study, we demonstrated the pivotal role of antioxidant levels on MDSCs survival and cardiac functional recovery by either reducing the antioxidant levels with diethyl maleate or increasing antioxidant levels with N-acetylcysteine (NAC). Both the anti- and pro-oxidant treatments dramatically influenced the survival of the MDSCs in vitro. When NAC-treated MDSCs were transplanted into infarcted myocardium, we observed significantly improved cardiac function, decreased scar tissue formation, and increased numbers of CD31(+) endothelial cell structures, compared to the injection of untreated and diethyl maleate-treated cells. These results indicate that elevating the levels of antioxidants in MDSCs with NAC can significantly influence their tissue regeneration capacity.

Abstract
BACKGROUND Acute renal damage has numerous causes, including renal ischemia-reperfusion injury. Due to its diverse actions, cepharanthine is used to treat many acute and chronic diseases, including pit viper bites, alopecia areata, and leucopenia in radiation therapy. In this study, we examined whether cepharanthine provides a renal-protective effect in a renal ischemia-reperfusion model. MATERIALS AND METHODS Male Wistar rats were divided into four groups that received the following treatments: induction of renal ischemia-reperfusion (I/R group); subcutaneous injection of cepharanthine (10 mg/kg) followed 1 h later by induction of renal ischemia-reperfusion (Cepha + I/R group); subcutaneous injection of cepharanthine (10 mg/kg) (Cepha group); and subcutaneous injection of saline followed 1 h later by sham treatment (control group). Rats were sacrificed 24 h after renal ischemia-reperfusion or sham treatment. Serum blood urea nitrogen (BUN) and creatinine (Cre) concentrations were determined, histologic examination was performed, and oxidative stress was evaluated in kidney tissue. In addition, antimycin A (AMA)-stimulated RAW264.7 cells were treated with cepharanthine to determine its antioxidant effects. RESULTS Serum BUN and Cre levels were increased in the I/R group; however, these increases were significantly inhibited in the Cepha + I/R group. Similarly, kidney tissue damage observed in the I/R group was attenuated in the Cepha + I/R group. In vitro, cells treated with both cepharanthine and AMA showed reduced reactive oxygen species activity compared with cells treated with AMA alone. CONCLUSIONS Our findings suggest that cepharanthine may be effective in the treatment of various types of ischemia-reperfusion injuries.

Abstract
The present study was designed to investigate the modulatory effects of rottlerin on ischemia reperfusion induced myocardial injury. Isolated rat hearts were exposed to 30 min of global ischemia followed by 120 min of reperfusion using Langendorff apparatus. Myocardial injury was assessed in the terms of infarct size, release of lactate dehydrogenase (LDH), creatine kinase (CK) enzymes. Rottlerin, a selective PKCdelta inhibitor, did not modulate ischemia-reperfusion (I/R) induced myocardial injury at low dose (3 microM). However, at moderate dose (6 microM) it significantly produced cardioprotective effects. On the contrary, rottlerin at high dose (12 microM) significantly enhanced I/R induced myocardial injury. However, administration of FR-167653 (1.1 microM, 2.2 microM), a selective p-38 mitogen activated protein kinase (p-38 MAPK) inhibitor, attenuated rottlerin (12 microM) mediated enhancement in I/R induced myocardial injury in a dose dependent manner. Per se administration of FR-167653 (1.1 microM, 2.2 microM) also attenuated I/R induced myocardial injury in a dose dependent manner. Pretreatment with rottlerin (6 microM) did not enhance the cardioprotective effects of FR-167653 (2.2 microM). It may be concluded that rottlerin mediated cardioprotective effects at moderate dose, possible due to inhibition of PKCdelta; while at high dose it enhanced I/R induced myocardial injury which may be attributed to activation of p-38 MAPK.
