Many researchers have wanted to enhance NMDA receptor signals to treat disorders such as schizophrenia. But at the same time, they need to avoid killing neurons with “excitotoxicity”, which comes from excess calcium entering the Read more
In 2018, Winship magazine had a feature story on pancreatic cancer. Our team developed an illustration that we hoped could convey the tumors’ complex structure, which contributes to making them difficult to treat. Oncologist Bassel El-Rayes described how the tumors recruit other cells to form a protective shell.
"If you look at a tumor from the pancreas, you will see small nests of cells embedded in scar tissue," he says. "The cancer uses this scar Read more
A study published in the May 17, 2010, issue of the journal Pediatrics found that one type of pesticide commonly used on fruits and vegetables may be contributing to attention deficit hyperactivity disorder, or ADHD, in children.
The study measured the levels of pesticide byproducts in the urine of 1,139 children from across the United States. Children with the highest concentration of pesticides in their urine were more likely to have symptoms of ADHD.
Barr says while the study doesnâ€™t prove causality between pesticide exposures and ADHD, it does shed light on how even low level daily exposures to pesticides could potentially impact cognitive health.
â€œIt seems very plausible that low-level daily exposures to pesticides can produce some subtle effects like ADHD or other neurological delays,â€ she says.
Barr notes that additional research is needed to confirm a connection to pesticides and ADHD, but says there are tips for limiting your exposure to commonly used pesticides.
â€œWeâ€™ve done studies here at Emory and also at CDC that have indicated that if you use organic food or if you wash your food properly prior to preparation, you can reduce the levels of these metabolites in your urine.Â Eat as much organic produce as possible, or wash your fruits and vegetables very well and that likely could decrease the chances of your children developing ADHD,â€ says Barr.
