Ketamine induces multiple individually distinct whole-brain functional connectivity signatures

mycolabadmin

This study examined how ketamine, a promising depression treatment, affects different people’s brains in different ways. Rather than averaging brain scans across all participants, researchers looked at individual differences and found that each person showed unique patterns of brain activity changes. The research suggests that personalized approaches to ketamine treatment, based on individual brain responses, could help identify which patients would benefit most from the therapy.

Current situation regarding psychedelics and magic mushroom in Korea

mycolabadmin

This article reviews the current status of psychedelic mushrooms and their potential medical uses in Korea. Several wild mushroom species containing psilocybin have been identified in Korea and can cause hallucinations and other nervous system effects lasting a few hours. While psychedelics show promise for treating depression and anxiety, Korea currently classifies them as controlled substances, and only approved clinical trials can be conducted with government permission.

Vaping danger: A hidden threat among Malaysia’s youth

mycolabadmin

A 15-year-old student in Malaysia was hospitalized after vaping a product labeled as having a magic mushroom flavor. Testing revealed the vape actually contained MDMB-4en-PINACA, a highly potent synthetic cannabinoid that is 100-200 times stronger than natural cannabis. This case highlights the danger of unregulated vaping products being mixed with illegal substances that can cause serious health effects including seizures, heart problems, and organ damage. Doctors and the public need to be aware of these hidden threats in vaping products.

GDF11 slows excitatory neuronal senescence and brain ageing by repressing p21

mycolabadmin

As we age, brain cells called excitatory neurons undergo senescence, similar to cellular ageing. This study found that a protein called GDF11 protects these neurons from ageing. When GDF11 was removed from excitatory neurons in mice, the neurons aged faster, leading to memory problems and shorter lifespans. The research reveals that GDF11 works by blocking p21, a molecule that promotes cellular ageing.

Mechanisms of Talaromyces marneffei induced CNS injury: Synergistic roles of tauopathy, pyroptosis, and microglial inflammation

mycolabadmin

A dangerous fungus called Talaromyces marneffei can invade the brain and cause serious damage in people with weakened immune systems. The study shows the fungus harms brain cells through two pathways: direct damage to neurons and indirect damage through activation of brain immune cells that release harmful inflammatory chemicals. Understanding these mechanisms could help develop better treatments for this life-threatening infection.
