1. Effects of perilipin-5 on lipid metabolism and high-sensitivity cardiac troponin I
SUMMARY OBJECTIVE: Heart attack is one of the most common causes of sudden death in adults. Therefore, early detection of heart attack and investigation of potential new biomarkers are of great importance. We investigated whether perilipin-5 is a potential biomarker by examining changes in perilipin-5 serum levels along with high-sensitivity cardiac troponi

2. The effects of dexketoprofen on renal ischemia-reperfusion injury: an experimental study
Abstract Objective Ischemia/reperfusion (I/R) may cause irreversible damage to tissues and organs. We evaluated the effects of dexketoprofen on a renal I/R model in rats. Methods The study included 30 male rats. Control group received 1 mL of saline. Dexketoprofen group received 1 mL (25 mg) of dexketoprofen intraperitoneally. After 60 minutes renal ischem

3. RhoA/ROCK-1 Signaling Pathway and Oxidative Stress in Coronary Artery Disease Patients
Abstract Introduction: Coronary artery disease (CAD) is an ischemic condition that occurs as a result of partial or complete interruption of blood flow by narrowing or complete blockage of the vessels supplying the heart, which are called coronary arteries. Our objective in this study is to investigate the RhoA/Rho-associated kinase (ROCK)-1 signaling pathw

4. Cardioprotective Effect of Cilostazol on Ischemia-Reperfusion Injury Model
Abstract Introduction: To clarify the potential protective role of cilostazol on rat myocardial cells with ischemia-reperfusion injury (IRI) models. Methods: The study was conducted with three groups of 10 Wistar rats (control group, rats without any coronary ischemia; sham group, rats with coronary ischemia but without cilostazol administration; and cilos

5. Astaxanthin protects against hearing impairment in diabetic rats
Abstract Objectives: Diabetes Mellitus (DM) causes an increase in oxidative stress that leads to deterioration in auditory functions. Astaxanthine (AST) is known to have strong antioxidant effects. In this study, the aim is to investigate the effect of AST against hearing loss that is due to DM. Methods: This study is an experimental animal study. The stud

6. Campsiandra laurifolia Reduces Oxidative Stress and Inflammation in Rats with Ulcerative Colitis
Abstract Ulcerative colitis (UC) affects the mucosa and submucosa of the large intestine. One of the mechanisms involved in its etiology is oxidative stress (OS), directly involved in the inflammatory process characteristic of UC. The Campsiandra laurifolia, known as acapurana, was described as possessing antioxidant properties. We used 24 male Wistar rats,

7. Postharvest ascorbic acid application maintained physiological and antioxidant responses of Guava (Psidium guajava L.) at ambient storage
Abstract Guava (Psidium guajava) is a highly perishable fruit with a short shelf life as physico-chemical changes occur continuously and rapidly after harvest leading to heavy postharvest losses. This experiment was laid down to unravel the effects of ascorbic acid (AA) on ripened guava fruits to improve its shelf life and quality. Four different concentrati

8. Negative early life experiences as risk factors for suicidal behavior in bipolar disorders
Ultrafiltration coupled with liquid chromatography-mass spectrometry (LC-MS) was established to screen xanthine oxidase (XO) inhibitors from Pueraria lobata root extract. Four compounds were screened out and identified as puerarin, daidzin, daidzein and genistein with half-maximal inhibitory concentration (IC50) values of 30.8, 5.31, 14.5 and 3.02 µg mL−1

10. Cyclocarya paliurus (Batal.) Iljinskaja polysaccharides alleviate type 2 diabetes mellitus in rats by resisting inflammatory response and oxidative stress
Abstract This study aimed to investigate the effects of Cyclocarya paliurus (Batal.) Iljinskaja polysaccharides (CPP) on the glucose-lipid metabolism in T2DM rats. T2DM model was established in 40 Wistar rats which were then randomly divided into model, CPP-1, CPP-2 and CPP-3 groups. Ten normal rats were selected as the control group. The CPP-1, CPP-2 and CP

11. Protective Effects of Adrenomedullin on Rat Cerebral Tissue After Transient Bilateral Common Carotid Artery Occlusion and Reperfusion
Abstract Objective: We aimed to investigate the protective effect of adrenomedullin (ADM) on cerebral tissue of rats with cerebral ischemia/reperfusion (I/R) injury. Methods: Thirty-two Wistar rats were randomized into four groups (n=8). In the I/R Group, bilateral common carotid arteries were clamped for 30 minutes and, subsequently, reperfused for 120 mi
