Subacute Testicular Toxicity to Cadmium Exposure Intraperitoneally and Orally

Oxidative Medicine and Cellular Longevity, Volume 2019, Issue 1, 2019., 2019
The toxic effects of cadmium (Cd) on reproductive parameters are widely described in the literature. Experimental models often make use of the intraperitoneal route (i.p.), although human intoxication occurs preferentially by the oral route and can be continuous.

Relationship between Oxidative Stress and Physical Activity in Women with Squamous Intraepithelial Lesions in a Cervical Cancer Control Program in the Brazilian Amazon

Oxidative Medicine and Cellular Longevity, Volume 2019, Issue 1, 2019., 2019
Human papillomavirus (HPV) infection is recognized as the most common sexually transmitted disease in the world, and there is a consensus on its role in the etiology of preneoplastic epithelial changes in the cervix. Through the process of lipid peroxidation, oxidative stress is found in the course of premalignant and malignant changes.

Relações patofisiológicas entre estresse oxidativo e arteriosclerose [PDF]

Química Nova, 2011
Oxidative stress is the result of an imbalance between oxidant and antioxidant species, with predominance of oxidative species with harmful action of reactive oxygen species (ROS) and reactive nitrogen species (RNS) on cells. Changes in the levels of nitric oxide (NO•) can be the cause and/ or a result of various pathophysiological processes.

Curcumin Supplementation Decreases Intestinal Adiposity Accumulation, Serum Cholesterol Alterations, and Oxidative Stress in Ovariectomized Rats

Oxidative Medicine and Cellular Longevity, Volume 2016, Issue 1, 2016., 2016
The aim of this study was to investigate the potential of curcumin oral supplementation (50 and 100 mg/Kg/day, for 30 days) in circumventing menopause‐associated oxidative stress and lipid profile dysfunctions in a rat ovariectomy (OVX) model. Female Wistar rats were operated and randomly divided into either sham‐operated or OVX groups.

Choline and Cystine Deficient Diets in Animal Models with Hepatocellular Injury: Evaluation of Oxidative Stress and Expression of RAGE, TNF‐α, and IL‐1β

Oxidative Medicine and Cellular Longevity, Volume 2015, Issue 1, 2015., 2015
This study aims to evaluate the effects of diets deficient in choline and/or cystine on hepatocellular injury in animal models (young male Wistar rats, aged 21 days), by monitoring some of the oxidative stress biomarkers and the expression of RAGE, TNF‐α, and IL‐1β.
