Roberta Diaz Brinton, director of the Center for Innovation in Brain Science at the University of Arizona, is investigating whether the drug allopregnanolone – a naturally occurring brain steroid – could promote a process called neurogenesis, which triggers brain cell growth and might restore cognitive function.

Coronavirus cases nationally are falling from their July peaks and some hard-hit states are showing signs of improvement – a hopeful sign even as the country deals with about 1,000 COVID-19 deaths every day. Arizona, once one of the hardest-hit states, has seen a dramatic improvement after Gov. Doug Ducey, who initially resisted stronger measures, closed bars and allowed localities to require masks. “Definitely things are improving and they’re actually improving quite dramatically,” said Joe Gerald, an associate professor at the University of Arizona's Mel and Enid Zuckerman College of Public Health.

The Michael J. Fox Foundation has awarded more than $8.8 million in wide-ranging grants to scientists aiming to better understand, diagnose and treat Parkinson's disease. One grant recipient is Dr. Lalitha Madhavan, an associate professor in the University of Arizona Department of Neurology at the College of Medicine - Tucson. She and her team are developing a human cellular system to help in the early identification and study of Parkinson’s mechanisms. Specifically, they want to develop dopamine neurons and patient-derived skin cells – called fibroblasts – for use in evaluating in clinical trials potential Parkinson's therapies and biomarkers.

While leading health organizations such as the World Health Organization and Centers for Disease Control and Prevention recommend the use of hand dryers, experts say misinformation about this equipment remains. Kelly Reynolds, a professor and Department Chair at the Mel and Enid Zuckerman College of Public Health at the University of Arizona, offered an explanation as to the root of these misconceptions, stating that, “Consumers may only read (sensationalized) headlines which can influence public opinion toward biased or erroneous conclusions, (but) the fact is, the breadth of data available does not favor one hand drying method as being more hygienic or safer.”

The Arizona Poison and Drug Information Center at the University of Arizona College of Pharmacy and Banner Health's Poison and Drug Information Center in Phoenix are warning residents statewide against using inappropriate medications and botanical products such as oleandrin to prevent or treat COVID-19.

Inappropriate medications – such as oleandrin, a derivative of oleander known to be toxic – used to prevent or treat COVID-19 could cause significant harm and no benefit, University of Arizona Health Sciences-based center and Banner Health center warn.

Bolstered by a $1.6 million grant, Dr. Timothy Bolger, at the University of Arizona Cancer Center, is studying how cells respond to stress and the role this process has in cancer growth and aging.

Understanding how cells respond to stress may provide new building blocks for designing future cancer and aging treatments. Timothy Bolger, a researcher at the University of Arizona Cancer Center, received a $1.6 million grant from the National Institutes of Health to investigate how cells respond to stress and the role this process may have in cancer growth and aging.

A University of Arizona Health Sciences cohort study of more than 50,000 menopausal women showed significant decrease in Alzheimer’s disease diagnosis.
