To examine the effects of maternal resveratrol in rats borne to dams with gestational high-fat diet (HFD)/obesity with or without postnatal high-fat diet. We first tested the effects of maternal resveratrol intake on placenta and male fetus brain in rats borne to dams with gestational HFD/obesity. Then, we assessed the possible priming effect of a subsequent insult, male offspring were weaned onto either a rat chow or a HFD. Spatial learning and memory were assessed by Morris water maze test. Blood pressure and peripheral insulin resistance were examined. Maternal HFD/obesity decreased adiponectin, phosphorylation alpha serine/threonine-protein kinase (pAKT), sirtuin 1 (SIRT1), and brain-derived neurotrophic factor (BDNF) in rat placenta, male fetal brain, and adult male offspring dorsal hippocampus. Maternal resveratrol treatment restored adiponectin, pAKT, and BDNF in fetal brain. It also reduced body weight, peripheral insulin resistance, increased blood pressure, and alleviated cognitive impairment in adult male offspring with combined maternal HFD and postnatal HFD. Maternal resveratrol treatment restored hippocampal pAKT and BDNF in rats with combined maternal HFD and postnatal HFD in adult male offspring dorsal hippocampus. Maternal resveratrol intake protects the fetal brain in the context of maternal HFD/obesity. It effectively reduced the synergistic effects of maternal HFD/obesity and postnatal HFD on metabolic disturbances and cognitive impairment in adult male offspring. Our data suggest that maternal resveratrol intake may serve as an effective therapeutic strategy in the context of maternal HFD/obesity.

Resveratrol (RSV) is a naturally occurring astragalus-like polyphenolic compound with remarkable weight loss properties. However, the mechanism of RSV in treating obesity is unclear. In this narrative review, we explored electronic databases (PubMed) for research articles from 2021 to the present using the keywords "resveratrol" and "obesity".

Evidence suggests that prenatal maternal immunological stress is associated with an increased risk of neurological and psychiatric disorders in the developing offspring. Protecting the embryo during this critical period of neurodevelopment, when the brain is especially vulnerable, is therefore crucial. Polyphenols, with their antioxidant and anti-inflammatory properties, offer promising therapeutic approaches.

This review addressed the most recent data (last 10 years) on exposure to phthalates in different scenarios and how the use of natural products could mitigate the harmful effects caused by exposure at different stages of development.
Abstract: This review article summarizes the experimental findings in rodents published between 2014 and 2024 concerning phthalates exposure and reproductive outcomes.

Background: Type 2 diabetes mellitus (T2DM) is primarily attributed to impaired insulin secretion caused by β cell dysfunction. 1,8-Cineole is a key bioactive compound in the essential oil extracted from Fructus Alpiniae Zerumbet, which possesses anti-inflammatory and antioxidant properties. Nevertheless, it remains elusive about the protective effect and precise mechanisms of 1,8-Cineole against the β cell deterioration in T2DM.

Article Synopsis
- Inhalation of crystalline silica (CS) can cause serious lung issues like chronic inflammation and pulmonary fibrosis (PF), which currently has few effective treatments.
- This study is the first to explore how resveratrol (Res) may help treat PF by using a mix of network pharmacology and experimental methods to understand its effects better.
- Results revealed that Res can reduce lung damage and other harmful effects by influencing the autophagy signaling pathway, specifically targeting the AMPK/mTOR pathway, highlighting its potential as a treatment for PF.
