Ischemia-reperfusion (IR) injury, a process involving the disruption and subsequent restoration of blood flow, is a significant contributing factor to both cardiovascular diseases and broader tissue damage. Carnosine, a natural dipeptide notably abundant in muscle tissue and recognized for its antioxidant attributes, may offer protective benefits against the deleterious effects of IR injury. A total of 24 rats were randomly allocated into four distinct groups: control, carnosine control, IR, and Carnosine + IR.

Background: Erythrocyte deformability, the ability of red blood cells to bend and twist as they pass through capillaries, is es-sential for tissue perfusion. This study investigates the effects and underlying mechanisms of rosmarinic acid treatment on erythrocyte deformability in rats subjected to lower limb ischemia-reperfusion injury.

Methods: The study was conducted on Wistar albino rats weighing 400-450 g.

Unlabelled: We evaluated the protective effects of melatonin against skeletal muscle ischemia-reperfusion injury, a significant cause of skeletal muscle damage. Ischemia-reperfusion (I/R) injury occurs due to a temporary restriction of blood flow (ischemia) followed by its restoration (reperfusion), triggering oxidative stress, inflammation, and cell death. Although current treatments are limited, melatonin's antioxidant and anti-inflammatory properties suggest potential benefits.

Article Synopsis
  • Erythrocyte deformability is essential for tissue perfusion, and this study investigates how Thymoquinone affects this property in rats with lower extremity ischemia-reperfusion injury.
  • Researchers divided Wistar rats into five groups, including a control and various Thymoquinone treatment groups, to examine its effects on erythrocyte deformability and other markers post-injury.
  • Results showed that Thymoquinone significantly improved erythrocyte deformability and morphology while increasing the activity of endothelial nitric oxide synthase compared to the untreated ischemia-reperfusion group.*

Background: This study aimed to investigate the incidence of postoperative atrial fibrillation (POAF) in patients undergoing off-pump versus on-pump coronary artery bypass grafting (CABG) under cardiopulmonary bypass (CPB).

Methods: A total of 3,197 consecutive patients (1,816 males, 1,381 females; mean age: 60.8 ± 9.

Article Synopsis
  • The study aimed to assess the effects of irisin in a mouse model experiencing hind limb ischemia reperfusion (I/R).
  • Mice were divided into four groups to analyze the impacts of irisin administration before the I/R procedure, focusing on biochemical and histopathological changes after 2 hours of ischemia and 2.5 hours of reperfusion.
  • Results indicated that irisin could enhance total antioxidant status and reduce inflammation, suggesting protective benefits against skeletal muscle damage due to ischemia reperfusion injury.

N-acetylcysteine (NAC) is an antioxidant which works as a free radical scavenger and antiapoptotic agent. N-acetylcysteine-amide (NACA) is a modified form of NAC containing an amide group instead of a carboxyl group of NAC. Our study aims to investigate the effectiveness of these two substances on erythrocyte deformability and oxidative stress in muscle tissue.

Pyoderma gangrenosum is a rare inflammatory ulcerative skin disease characterized by painful, progressive necrosis of wound margins. A 34-year-old male patient was admitted to our clinic with progressive ulcerative lesion at the wound site after endovenous laser ablation and varicose vein surgery. Although parenteral antibiotherapy was initiated with the diagnosis of wound infection, rapid progression was observed in the lesion.

Introduction: Many structural and functional damages are observed in cells and tissues after reperfusion of previously viable ischemic tissues. Acute ischemia reperfusion (I/R) injury of lower extremities occurs especially when a temporary cross-clamp is applied to the abdominal aorta during aortic surgery. Research regarding the treatment of I/R injury has been increasing day-by-day.

Background: Ischemia reperfusion injury (I/R) in hind limb is a frequent and important clinical phenomenon. Many structural and functional damages are observed in cells and tissues in these kinds of injuries. In this study, we aimed to evaluate the effect of picroside II on lipid peroxidation and erythrocyte deformability during I/R in rats.
