Assessment of Oxidative Stress Biomarkers in Rat Blood.

Redox status assessments are time-consuming, require a large volume of samples and great reagent amounts, and are not adequately described for methodological reproducibility. Here, the objective was to standardize redox balance determination, based on previously described spectrophotometric tests in pregnant rats, to improve precision, time dispensed, and the volume of samples and reagents, while maintaining accuracy and adequate cost benefits. This protocol summarizes oxidative stress markers, which focus on spectrophotometric tests for the assessment of thiobarbituric acid-reactive substances, reduced thiol groups, and hydrogen peroxide, as well as the antioxidant activity of superoxide dismutase, glutathione peroxidase, and catalase in washed erythrocyte and serum samples from full-term pregnant rats.

Severe Diabetes Induction as a Generational Model for Growth Restriction of Rat.

We used uncontrolled maternal diabetes as a model to provoke fetal growth restriction in the female in the first generation (F) and to evaluate reproductive outcomes and the possible changes in metabolic systems during pregnancy, as well as the repercussions at birth in the second generation (F). For this, nondiabetic and streptozotocin-induced severely diabetic Sprague-Dawley rats were mated to obtain female pups (F), which were classified as adequate (AGA) or small (SGA) for gestational weight. Afterward, we composed two groups: F AGA from nondiabetic dams (Control) and F SGA from severely diabetic dams (Restricted) (n minimum = 10 animals/groups).

Effects of diabetes between generations on the pre-embryos of rats.

Exposure to maternal hyperglycemia and high-fat diet consumption after weaning in rats: repercussions on periovarian adipose tissue.

Clinical and epidemiological studies show that maternal hyperglycemia can change the programming of offspring leading to transgenerational effects. These changes may be related to environmental factors, such as high-fat diet (HFD) consumption, and contribute to the comorbidity onset at the adulthood of the offspring. The objective of this study was to evaluate the hyperglycemic intrauterine environment, associated or not with an HFD administered from weaning to adult life on the periovarian adipose tissue of rat offspring Maternal diabetes was chemically induced by Streptozotocin.

Metabolic changes in female rats exposed to intrauterine hyperglycemia and postweaning consumption of high-fat diet†.

We evaluated the influence of the hyperglycemic intrauterine environment and postweaning consumption of a high-fat diet (HFD) on the glycemia, insulin, lipid, and immunological profile of rat offspring in adulthood. Female rats received citrate buffer (Control-C) or Streptozotocin (a beta cell-cytotoxic drug to induce diabetes-D) on postnatal day 5. In adulthood, these rats were mated to obtain female offspring, who were fed a standard diet (SD) or HFD from weaning to adulthood (n = 10 rats/group).
