Administration of the antioxidant n-acetyl-cysteine in pregnant mice has long-term positive effects on metabolic and behavioral endpoints of male and female offspring prenatally exposed to a high-fat diet

A growing body of evidence suggests the consumption of high-fat diet (HFD) during pregnancy to model maternal obesity and the associated increase in oxidative stress (OS), might act as powerful prenatal stressors, leading to adult stress-related metabolic or behavioral disorders. We hypothesized that administration of antioxidants throughout gestation might counteract the negative effects of prenatal exposure to metabolic challenges (maternal HFD feeding during pregnancy) on the developing fetus.

Modulation of pain sensitivity by chronic consumption of highly palatable food followed by abstinence: emerging role of fatty acid amide hydrolase

There is a strong relationship between palatable diet and pain sensitivity, and the cannabinoid and opioid systems might play an important role in this correlation. The palatable diet used in many animal models of obesity is the cafeteria (CAF) diet, based on human food with high sugar, salt, and fat content. In this study, we investigated whether long-term exposure to a CAF diet could modify pain sensitivity and explored the role of the cannabinergic system in this modification.

Beneficial effects of a selected probiotic mixture administered to high fat-fed mice before and after the development of obesity

We investigated the efficacy of different probiotics and bacteria used in dairy products to prevent the development of obesity and ameliorate established obesity in C57BL/6J mice fed a high fat diet (HFD). For the preventive efficacy, Lactobacillus rhamnosus GG, L. acidophilus LA1/K8, a mixture of Bifidobacterium lactis Bi1, B. breve Bbr8 and B. breve BL10 (B. mix), or a mixture of L. bulgaricus Lb2 and S. termophilus Z57 were given to mice before (2 weeks) and together with HFD (12 weeks).
