Treating mental disorders with fewer side effects

Now, researchers have managed to genetically modify yeast cells to produce drugs for mental disorders such as schizophrenia with fewer side effects.

“Development of medicines from natural plant substances is widely used. However, since plants do not produce these substances to fight human diseases, there is often a need to modify them to make them more effective and safe,” said Michael Krogh Jensen, a senior researcher at DTU Biosustain and co-founder of the biotech company Biomia.

The challenge of measuring adult neurogenesis is difficult, but it’s not impossible. A big part of the solution is knowing what to measure and where. While this new study was performed on rats—and therefore may be a poor predictor of what we’ll see in humans—it can direct future research by showing neuroscientists where to look and what to look for.

And unlike the hard problem of consciousness, unraveling the mysteries of adult neurogenesis may have clinical applications. Better the lifecycle of neurons may reveal how neurological disorders such as Parkinson’s and Alzheimer’s disease emerge. There’s even research linking disorders such as depression and anxiety to neurogenesis activity.

This knowledge may lead to new treatments, but if not, it could also reveal a better understanding of how our lifestyles and environments support brain health and regeneration throughout human life.

Only 2% of Alzheimer’s is 100% genetic. The rest is up to your daily habits.

People want a perfect memory. They wish that they can remember everything that they want to remember. But it doesn’t work like that.

Most people over the age of 50 think that forgetting someone’s name or forgetting why they went into the kitchen is a sign of Alzheimer’s. It isn’t. Most of our forgetfulness is perfectly normal.

A team of surgeons in New York has performed the world’s first transplant of an entire eye in a procedure widely hailed as a medical breakthrough, although it isn’t yet known whether the man will ever see through the donated eye.

The groundbreaking surgery involved removing part of the face and the whole left eye—including its blood supply and optic nerve—of a donor and grafting them onto a lineworker from Arkansas who survived a 7,200-volt electric shock in June 2021.

Aaron James, 46, suffered extensive injuries including the loss of his left eye, his dominant left arm above the elbow, his nose and lips, front teeth, left cheek area and chin.

Researchers at the University of Oxford, UK have found that butyrate, a short-chain fatty acid produced by gut bacteria, can boost the antimicrobial activity of immune cells in the gut, possibly helping them better fend off bacterial infections and improve immune health.

The study, which exposed human monocytes and macrophages (immune cells) to bacterial infections to simulate real-world scenarios in the lab, backs up ongoing research into the benefits of butyrate as a therapeutic component to combat conditions—from food allergies to inflammatory bowel disease (IBD) and support immune system function.

Two recent studies due to be presented as posters at the American Heart Association (AHA) Scientific Sessions 2023 between November 11–13 examine how frequent cannabis use could potentially lead to increased chances of cardiology issues, including heart attack, stroke, or heart failure. These studies were conducted by an international team of researchers and holds the potential to help scientists, medical professionals, and the public better understand the long-term health risks associated with cannabis use, specifically pertaining to cardiovascular concerns.

For the first study, which was conducted by the All of Us Research Program, researchers enlisted 156,999 participants who had not experienced heart failure at the time of the study’s enrollment to take part in a survey-based study to evaluate their cannabis use habits and conduct a follow-up survey 45 months later. The results indicated that heart failure emerged with 2,958 (1.88 percent) of the participants during the 48-month study period along with a 34 percent increased risk of emerging heart failure for participants were reported daily cannabis use compared to participants who didn’t use cannabis.

“Our results should encourage more researchers to study the use of marijuana to better understand its health implications, especially on cardiovascular risk,” said Dr. Yakubu Bene-Alhasan, who is a resident physician at Medstar Health and lead author of the study. “We want to provide the population with high-quality information on marijuana use and to help inform policy decisions at the state level, to educate patients and to guide health care professionals.”
