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.

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.

Nutritional Supplementation with the Mushroom Agaricus sylvaticus Reduces Oxidative Stress in Children with HIV

Canadian Journal of Infectious Diseases and Medical Microbiology, Volume 25, Issue 5, Page 257-264, 2014., 2014
BACKGROUND: The involvement of free radicals and oxidative stress in HIV infection has been extensively studied, and the benefits of antioxidant supplementation in animal studies have been demonstrated. However, few studies have demonstrated a benefit in clinical studies.

Characterization of Blood Oxidative Stress in Type 2 Diabetes Mellitus Patients: Increase in Lipid Peroxidation and SOD Activity

Oxidative Medicine and Cellular Longevity, Volume 2012, Issue 1, 2012., 2012
This study evaluated the oxidative stress through enzymatic and nonenzymatic biomarkers in diabetic patients with and without hypertension and prediabetics. The SOD and CAT (in erythrocytes) and GPx (in plasma) enzymatic activities, plasma levels of lipid peroxidation, and total thiols were measured in the blood of 55 subjects with type 2 diabetes and ...

Quercetin Treatment Ameliorates Systemic Oxidative Stress in Cirrhotic Rats

International Scholarly Research Notices, Volume 2011, Issue 1, 2011., 2011
Our aim was to investigate whether the antioxidant quercetin protects against liver injury and ameliorates the systemic oxidative stress in rats with common bile duct ligation. Secondary biliary cirrhosis was induced through 28 days of bile duct obstruction. Animals received quercetin (Q) after 14 days of obstruction.
