Investigation of the effects of astaxanthin in experimental polycystic ovary syndrome (PCOS) in rats.

Objectives: The aim of this study was to investigate the effect of Astaxanthin (ASX) on ovaries in letrozole-induced polycystic ovary syndrome (PCOS) model in female rats by histopathological, immunohistochemical and biochemical techniques.

Materials And Methods: Seventy two Sprague-Dawley female rats with an average weight of 200-250 gr and 10-12 weeks old were randomly divided into 9 groups. PCOS model was applied to all groups except healthy group.

Lercanidipine alleviates doxorubicin-induced lung injury by regulating PERK/CHOP and Bax/Bcl 2/Cyt c pathways.

Doxorubicin (DOX), which is used to treat various cancers and hematological malignancies, has limited therapeutic application due to its toxicity in tissues and organs. These toxic effects occur through alterations in intracellular calcium regulation, elevated cell stress and oxidative damage, and increased apoptosis. Lercanidipine (LRD) is a long-acting antihypertensive calcium channel blocker with anti-inflammatory, anti-apoptotic, and antioxidant effects.

Antipsychotics Induced Reproductive Toxicity by Stimulating Oxidative Stress: A Comparative in Vivo and in Silico Study.

The pathophysiological mechanism behind the link between antipsychotic drugs and sexual dysfunction is still unknown. The goal of this research is to compare the potential effects of antipsychotics on the male reproductive system. Fifty rats were randomly assigned into the five groups indicated: Control, Haloperidol, Risperidone, Quetiapine and Aripiprazole.

Histopathological Overview of Experimental Ulcer Models.

Histopathology is the process of examining tissue that includes all the changes, when a diseased tissue shows compared to a healthy group with a result of a histological observation. Histopathology has become an essential process in medical experimental research and medical experimental models. Scientists have developed medical experimental animal models for these reasons and have pioneered new drug research for many years.

Nicotinamide Riboside Preserves Ovarian Injury in Experimental Sepsis Model in Rats.

Objective: The aim of the study is to investigate the protective effects of nicotinamide riboside on oxidative stress in an experimental sepsis model created by cecal ligation and puncture.

Materials And Methods: Rats were divided into 3 groups randomly: sham-operated (control) group, sep- sis group, and nicotinamide riboside-treated group. Sepsis model-induced cecal ligation and puncture was applied to sepsis group rats.
