Northwestern University researchers have uncovered how ketamine delivers rapid and prolonged depression relief by activating new neurons for immediate effects and increasing their production for lasting benefits. This breakthrough could lead to safer, ketamine-inspired antidepressants.
Exploring the Impact of Hydrolyzed Collagen Oral Supplementation on Skin Rejuvenation: A Systematic Review and Meta-Analysis
With increasing life expectancy, the quest for skin rejuvenation has gained prominence among individuals of diverse age groups. The popularity of nutricosmetics, notably dietary supplements, has garnered significant attention in recent years. Many scientific investigations have amassed compelling evidence highlighting the positive impact of hydrolyzed collagen supplementation in mitigating the visible signs of skin aging. This study aims to know the powerful effect of hydrolyzed collagen on the skin. This research method is to conduct a systematic review followed by a meta-analysis of the clinical trial focusing on randomized, double-blind, and controlled trials that examined the oral consumption of hydrolyzed collagen and reported outcomes related to skin aging, wrinkles, moisture levels, elasticity, and firmness. The selected articles from CENTRAL, PubMed, Google Scholar, and ScienceDirect databases were published from 2017 to 2023. The subsequent meta-analysis, comprising 14 distinct studies and a collective cohort of 967 participants, revealed encouraging findings favoring hydrolyzed collagen supplementation. It consistently demonstrated substantial enhancements in skin moisture levels and elasticity compared to the placebo group, a trend robustly corroborated by subgroup analysis. These compelling findings underscore the effectiveness of a 12-week regimen of hydrolyzed collagen supplementation in revitalizing the skin by augmenting its hydration and elasticity.
AI can predict Alzheimer’s disease up to seven years before symptoms appear, study finds

Dementia prevention, intervention, and care: 2020 report of the Lancet Commission
The number of older people, including those living with dementia, is rising, as younger
age mortality declines. However, the age-specific incidence of dementia has fallen
in many countries, probably because of improvements in education, nutrition, health
care, and lifestyle changes. Overall, a growing body of evidence supports the nine
potentially modifiable risk factors for dementia modelled by the 2017 Lancet Commission
on dementia prevention, intervention, and care: less education, hypertension, hearing
impairment, smoking, obesity, depression, physical inactivity, diabetes, and low social
contact.
