Acute Effects of Psilocybin After Escitalopram or Placebo Pretreatment in a Randomized, Double-Blind, Placebo-Controlled, Crossover Study in Healthy Subjects

mycolabadmin

This study examined whether taking the antidepressant escitalopram before using psilocybin affects the drug’s effects. Twenty-three healthy participants took either escitalopram or placebo for two weeks, then received a dose of psilocybin. Surprisingly, escitalopram did not reduce the positive mood effects of psilocybin and actually reduced some negative side effects like anxiety and bad feelings. The combination appeared safe with no increased cardiovascular risks.

The molecular mechanisms through which psilocybin prevents suicide: evidence from network pharmacology and molecular docking analyses

mycolabadmin

Researchers used computer-based analysis to understand how psilocybin, a compound found in certain mushrooms, might help prevent suicide. They identified four key proteins that psilocybin interacts with and found that it works through serotonin and calcium signaling pathways in the brain, which are known to be involved in depression and suicidal behavior. While these findings are promising, more research is needed to confirm these effects in humans before psilocybin can be used clinically for suicide prevention.

Epigenome-wide association study of BMI and waist-to-hip ratio and their associations with dietary patterns in Korean adults

mycolabadmin

This research examined how different types of obesity (overall body weight versus belly fat) are associated with changes in DNA methylation patterns in Korean adults. The study found that certain DNA regions become less methylated in obese individuals, and that these epigenetic changes are linked to different dietary patterns. The findings suggest that specific foods may influence these epigenetic modifications differently depending on whether someone has overall obesity or more belly fat, opening new possibilities for using diet to prevent or manage obesity.
