Researchers estimate survival chances during CPR for cardiac arrest

A US study published in The BMJ found that a person's chance of surviving while receiving CPR for cardiac arrest declines rapidly from 22% after one minute to less than 1% after 39 minutes. The likelihood of leaving hospital with no major brain damage also decreases significantly after 32 minutes without heartbeat.

New direct links discovered between the brain and its surrounding environment

Researchers have found a connection between the brain and its tough protective covering, the dura mater, allowing waste fluid to leave the brain while exposing it to immune cells. This discovery has implications for neural-immune system responses and aging, potentially leading to new treatments for neurodegenerative diseases.

Spent hemp biomass: A feed use that supports milk production in dairy cows

A new study published in the Journal of Dairy Science explores the use of spent hemp biomass as a feed ingredient for lactating dairy cows. The research shows that hemp biomass is safe and does not negatively affect milk production or animal health, despite being less palatable due to its characteristic smell. The study suggests potent...

Scientists discover that a protein associated with neurodegenerative diseases is also linked to childhood brain cancer

A study conducted at a FAPESP-supported research center discovered a link between the protein VAPB and tumor cell proliferation in medulloblastoma, one of the most common and aggressive brain tumors in children. High expression of VAPB correlated with reduced patient survival.

Johns Hopkins researchers make progress toward developing blood tests for psychiatric and neurological disorders

Johns Hopkins researchers have made progress toward developing a blood test to identify disease-associated changes in the brain linked to postpartum depression and other psychiatric disorders. They identified 26 placental mRNAs present in maternal blood only during pregnancy, which reflected changes occurring inside the tissues.
