Resveratrol and Sir2 Reverse Sleep and Memory Defects Induced by Amyloid Precursor Protein.

Resveratrol (RES), a natural polyphenolic phytochemical, has been suggested as a putative anti-aging molecule for the prevention and treatment of Alzheimer's disease (AD) by the activation of sirtuin 1 (Sirt1/Sir2). In this study, we tested the effects of RES and Sirt1/Sir2 on sleep and courtship memory in a Drosophila model by overexpression of amyloid precursor protein (APP), whose duplications and mutations cause familial AD. We found a mild but significant transcriptional increase of Drosophila Sir2 (dSir2) by RES supplementation for up to 17 days in APP flies, but not for 7 days.

Incidence and predictors of paternal anxiety and depression following fetal abnormalities requiring pregnancy termination: a cross-sectional study in China.

Background: China is a country with a high prevalence of fetal abnormalities. Termination of pregnancy for fetal abnormalities (TOPFA) is a devastating traumatic event for parents and families, resulting in serious and lasting psychological problems. The impact of TOPFA on mothers has been extensively explored, but little research has been conducted on the resulting paternal psychological problems.

Upregulation of IP receptor mediates APP-induced defects in synaptic downscaling and sleep homeostasis.

Evidence suggests that impaired synaptic and firing homeostasis represents a driving force of early Alzheimer's disease (AD) progression. Here, we examine synaptic and sleep homeostasis in a Drosophila model by overexpressing human amyloid precursor protein (APP), whose duplication and mutations cause familial early-onset AD. We find that APP overexpression induces synaptic hyperexcitability.

Meta-Analysis Study on Treatment of Children's Attention Deficit Disorder with Hyperactivity.

With the development of society and the economy, the prevalence of attention deficit hyperactivity disorder (ADHD) has been increasing. Due to its high comorbidity and high harm, it has received increasing attention. It causes damage to functions in multiple areas, and this damage may continue into adulthood.
