Pyrethroids are important insecticides used largely because of their high activity as an insecticide and their low mammalian toxicity. Some studies have demonstrated that these products show neurotoxic effects on the mammalian central nervous system. The aim of the present study was to investigate the propensity of permethrin to induce oxidative stress in adolescent rats and its possible attenuation by Vitamin E alone or+Coenzyme Q(10). Data indicated that adolescent rats exposed to permethrin exhibited alteration in the locomotor activity and plasma membrane fluidity of striatum. Vitamin E+Q(10) and Vitamin E alone supplementation reversed the negative effect on central nervous system. Permethrin alteration of striatum plasma membrane fluidity was restored by Vitamin E+Q(10). Data obtained from red blood cells showed that permethrin did not induce any modification of plasma membrane fluidity in adolescent rats, whereas antioxidants supplementation induced pro-oxidant effect. In summary some differences between antioxidant treatments were observed at striatum level: Coenzyme Q(10)+Vitamin E maintains plasma membrane fluidity, while Vitamin E is more effective to preserve GSH level.

Disturbance in sleep and activity rhythms are significant health risks associated with alcohol use during adolescence. Many investigators support the theory of a reciprocal relationship between disrupted circadian rhythms, sleep patterns, and alcohol usage. However, in human studies it is difficult to disentangle other factors (i.

Persistent post-surgical pain (PPSP) occurs in a proportion of patients following surgical interventions. Research suggests that specific microbiome components are important for brain development and function, with recent studies demonstrating that chronic pain results in changes to the microbiome. Consumption of a high fat, high sugar (HFHS) diet can drastically alter composition of the microbiome and is a modifiable risk factor for many neuroinflammatory conditions.

Maternal exposure to ozone during implantation results in reduced fetal weight gain in rats. Offspring from ozone-exposed dams demonstrate sexually dimorphic risks to high-fat diet feeding in adolescence. To better understand the adolescent hepatic metabolic landscape following fetal growth restriction, RNA sequencing was performed to characterize the effects of ozone-induced fetal growth restriction on male and female offspring.

Previous studies suggest that early-life stress (ELS) induced by early maternal separation and isolation (MS) stress during the stress hyporesponsive period (SHRP) leads to increased curiosity-like and increased risky decision-making behaviour in adolescence. Evidence suggests that dietary interventions early in adolescence could play an important role in mitigating the detrimental effects of MS stress on risky decision-making behaviour. Hence, the present study hypothesized that nutritional supplements such as saturated fat (SFA) and/or polyunsaturated fat (PUFA) would be beneficial in ameliorating the impact of MS stress on risky decision-making behaviour when incorporated into the diet during early adolescence.

Background/objectives: Both hyperandrogenism (HA) and vitamin D deficiency (VDD) can separately lead to impaired vascular reactivity and ovulatory dysfunction in fertile females. The aim was to examine the early interactions of these states in a rat model of PCOS.
Methods: Four-week-old adolescent female rats were divided into four groups: vitamin D (VD)-supplemented ( = 12); VD-supplemented and testosterone-treated ( = 12); VDD- ( = 11) and VDD-and-testosterone-treated ( = 11).
