1. Antioxidant Effect of Curcumin on the Prevention of Oxidative Damage to the Cochlea in an Ototoxic Rat Model Based on Malondialdehyde Expression
Abstract Introduction Aminoglycoside, as an antimicrobial medication, also has side-effects on the inner ears, bringing about hearing disorders. Curcumin has been proven to be a strong scavenger against various reactive oxygen species (ROS), and the increase in ROS production is considered to play an important role in the process of hearing disorder. Objec

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. 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

5. Productivity and analysis of morphological characters of experimental strawberry genotypes
RESUMO Mundialmente o consumo de morangos é bastante apreciado, tanto na forma in natura ou industrializada. A produção brasileira depende da importação de mudas de morangueiro de países como Espanha, Chile e Argentina, as quais são cultivares melhoradas em climas temperados, e, consequentemente, não se adaptam bem às condições tropicais brasileir

6. Evaluation of maternal antibodies against rabies in puppies and kittens in Mazandaran Province, Iran
RESUMO A raiva é uma doença zoonótica crítica de alto risco, que surgiu como um importante problema de saúde pública. Há investigações limitadas que exploram anticorpos derivados da maternidade (MDA) em filhotes e gatos de todo o mundo. Além disso, não existe tal pesquisa em nenhuma província do Irã. Este estudo mediu o nível sérico do MDA em

7. 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

8. Effect of mechanical ventilation during cardiopulmonary bypass on oxidative stress: a randomized clinical trial
Abstract Background: Cardiopulmonary bypass (CPB) causes systemic oxidative stress response and endothelial damage in systemic organs. We investigated the effects of positive end-expiratory pressure (PEEP) and mechanical ventilation (MV) applications on oxidative stress in CPB. Methods: Seventy-one patients were recruited and 60 completed the study. Random

10. Benzophenone Derivatives Showed Dual Anti-Inflammatory and Antiproliferative Activities by Inhibiting COX Enzymes and Promote Cyclin E Downregulation
Considering the promising antitumor effects of compounds with dual anti-inflammatory and antiproliferative activities, thus benzophenones analogs (2-7) were evaluated on in vivo anti-inflammatory assay and molecular docking analysis. Those with the best molecular docking results were in vitro evaluated on cyclooxygenase (COX) enzymes and tested regarding ant
