SUBJECT We evaluated the efficacy for concomitant use of ischemic preconditioning (IPC) and cardioplegic arrest with adenosine premedication on myocardial protection. METHODS Twenty-one pigs were divided into three groups: 1) control group, 2) IPC group which had IPC, 3) IPC+adenosine triphosphate (ATP) group which had an administration of 140 gamma of ATP (Adetphos, Kowa, Tokyo, Japan) durin...

Objective(s): Liver transplantation is the most important therapy for end-stage liver disease and ischemia reperfusion (I/R) injury is indeed a risk factor for hepatic failure after grafting. The role of miRNAs in I/R is not completely understood. The aim of this study was to investigate the potential protective role of the mesenchymal stem cells (MSCs) and ischemic pr...

Ischemic preconditioning (IPC) is induced by exposure to brief durations of transient ischemia, which results in ischemic tolerance to a subsequent longer or lethal period of ischemia. In the present study, the effects of IPC (2 min of transient cerebral ischemia) were examined on immunoreactivity of platelet‑derived growth factor (PDGF)‑BB and on neuroprotection in the gerbil hippocampal CA1 r...

Ischemic or myocardial preconditioning (IPC) is a phenomenon whereby brief periods of ischemia have been shown to protect the myocardium against a more sustained ischemic insult. The result of IPC may be manifest as a marked reduction in infarct size, myocardial stunning, or incidence of cardiac arrhythmias. Whereas many endogenous neurotransmitters, peptides, and hormones have been proposed to...

Williams, N, Russell, M, Cook, CJ, and Kilduff, LP. Effect of ischemic preconditioning on maximal swimming performance. J Strength Cond Res 35(1): 221–226, 2021—The effect (IPC) performance was examined. Using a randomized, crossover design, national- international-level swimmers (n = 20; 14 men, 6 women) participated in 3 trials (Con, IPC-2h, IPC-24h). Lower-body IPC (4 × 5-minute bilateral bl...

Background: Antioxidants such as α-tocopherol (vitamin E) and β-carotene (vitamin A) play an important role in protective effect of repeated brief periods of ischemia, namely ischemic preconditioning (IPC). Values of these antioxidants were investigated and compared after induction of ischemia reperfusion (IR) and kidney IPC in both male and female rats. Methods: Forty eight Wistar rats were di...

PURPOSE In nonocular systems, activation of opioid receptors has been shown to ameliorate tissue damage induced by ischemic stress. The current study was an investigation of whether opioid receptors activated by endogenous or exogenous agonists can ameliorate ischemic retinal injury. METHODS In an investigation of whether endogenous opioid receptor-activation reduces ischemic injury, the effe...

BACKGROUND Cardiac protection afforded by ischemic preconditioning (IPC) and anesthetic preconditioning (APC) are significantly reduced in the senescent myocardium. The authors hypothesized that age would differentially modulate gene expression induced by IPC and APC in vivo. METHODS Affymetrix RAT EXON ST 1.0 gene chips (Affymetrix, Santa Clara, CA) were used to explore the transcriptional r...

Renal ischemic reperfusion (IR) injury is a significant clinical problem in anesthesia and surgery. Recently, it was demonstrated that both renal ischemic preconditioning (IPC) and systemic adenosine pretreatment protect against renal IR injury. In cardiac IPC, pertussis toxin-sensitive G-proteins (i.e., G(i/o)), protein kinase C (PKC), and ATP-sensitive potassium (K+(ATP)) channels are implica...
