1. 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

2. 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,

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. 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. 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

6. Photosynthetic and enzymatic metabolism of Ormosia arborea (Vell.) Harms under different water availabilities
Resumo Nesta pesquisa, hipotetizamos que as mudas de Ormosia arborea (Vell.) Harms crescem melhor e alcançam maiores níveis de troca gasosas quando cultivadas em solos com maior disponibilidade de água. Assim, este estudo foi desenvolvido para avaliar as respostas metabólicas das mudas a diferentes níveis de disponibilidade hídrica. A irrigação foi r

7. Fibroblast morphology, growth rate and gene expression in facial melasma
Abstract Background: In addition to melanocytic hyperfunction, changes are observed in the upper dermis of melasma, and fibroblasts play a central role in collagen synthesis and pigmentation induction. Objective: To explore the morphology, growth rate, and gene expression profile of fibroblasts from the skin with melasma in comparison to fibroblasts from t

11. Prognostic predictors of lymph node metastasis in penile cancer: a systematic review
ABSTRACT Purpose: Squamous cell carcinoma (SCC) of the penis is a rare disease in developed countries but is associated with significant morbidity and mortality. A crucial prognostic factor is the presence of inguinal lymph node metastases (ILNM) at the time of diagnosis. At least 25% of cases have micrometastases at the time of diagnosis. Therefore, we per
