This study was to explore whether repeated non-invasive limb ischemic pre-conditioning (NLIP) can confer an equivalent cardioprotection against myocardial ischemia-reperfusion (I/R) injury in acute diabetic rats to the extent of conventional myocardial ischemic pre-conditioning (MIP) and whether or not the delayed protection of NLIP is mediated by reducing myocardial oxidative stress after ischemia-reperfusion. Streptozotocin-induced diabetic rats were randomized to four groups: Sham group, the I/R group, the MIP group and the NLIP group. Compared with the I/R group, both the NLIP and MIP groups showed an amelioration of ventricular arrhythmia, reduced myocardial infarct size, increased activities of total superoxide dismutase (SOD), manganese-SOD and glutathione peroxidase, increased expression of manganese-SOD mRNA and decreased xanthine oxidase activity and malondialdehyde concentration (All p < 0.05 vs I/R group). It is concluded that non-invasive limb ischemic pre-conditioning reduces oxidative stress and attenuates myocardium ischemia-reperfusion injury in diabetic rats.

Background And Purpose: To investigate the impact of a history of ischemic stroke or transient ischemic attack (TIA) on the effectiveness of remote ischemic conditioning (RIC) for outcomes in acute ischemic stroke patients.
Methods: We conducted a post hoc analysis of the Remote Ischaemic Conditioning for Acute Moderate Ischaemic Stroke (RICAMIS) trial. Patients in RICAMIS were categorized into two groups according to a history of stroke.

Purpose: To mitigate ischemia-reperfusion injury (IRI) triggered in solid organ transplant procedures, we aimed to evaluate the effects of multi-organ abdominal ischemic preconditioning (MAIP) in the context of renal IRI.
Methods: An experimental kidney transplant model was conducted. Rats were divided into three groups: an intervention free basal group from which physiological data was collected; a control group (CT), which consisted of transplanted animals without MAIP; and a treated group, in which a MAIP protocol was implemented in the donor during the procurement of the left kidney, monitoring the recipient for 24 hours.

The aim of this study was to assess if ischaemic preconditioning (IPC) can reduce pain perception and enhance corticospinal excitability during voluntary contractions. In a randomised, within-subject design, healthy participants took part in three experimental visits after a familiarisation session. Measures of pressure pain threshold (PPT), maximum voluntary isometric force, voluntary activation, resting twitch force, corticospinal excitability and corticospinal inhibition were performed before and ≥10 min after either, unilateral IPC on the right leg (3 × 5 min); a sham protocol (3 × 1 min); or a control (no occlusion).

Objective: Limb ischemia-reperfusion injury caused by repeated tourniquet application usually leads to acute kidney injury, adversely affecting patient prognosis. This study aimed to investigate the renoprotective effect of remote ischemic preconditioning (RIPC) in patients undergoing extremity surgery with repeated tourniquet application.
Methods: 64 patients were enrolled and randomly divided into an RIPC group and a control group, with 32 patients in each.
Remote ischemic preconditioning on perioperative autonomic nervous system function and postoperative recovery in patients undergoing cholecystectomy.

Background: Cholecystectomy often disrupts autonomic balance, impacting recovery. Remote ischemic preconditioning (RIPC) may enhance ANS function and protect organs, but its role in cholecystectomy is unclear.
Methods: In this randomized controlled trial, 80 patients aged 45 to 65 years, scheduled for elective laparoscopic cholecystectomy, were randomly assigned to either the RIPC group or the control group.
