SARS-CoV-2 has given scientists a plethora of vaccines to evaluate. The response after the Johnson & Johnson vaccine, for instance, elicits a weaker immune response than the mRNA vaccines initially, “and then it actually starts to get better over time,” says Deepta Bhattacharya, PhD, a professor and immunologist at the College of Medicine – Tucson.

University of Arizona Health Sciences researchers discovered a potential treatment to reduce the risk of post-stroke dementia, which may be influenced by the immune response to dead brain tissue left in the wake of a stroke, according to a study published in the Journal of Neuroscience.

Solutions require complex, sustained effort to move the mountain of historical racism in medicine and the systemic ways it may exhibit itself today.

This free service is part of a research project on fatty liver, particularly non-alcoholic, at the Mel and Enid Zuckerman Arizona College of Public Health, which seeks to estimate the presence of scarring and fat in the liver of Hispanic inhabitants of Southern Arizona.

The U.S. healthcare industry is poised to grow tremendously over the next decade, but that doesn't mean its workers will reap the benefits. Not even doctors are safe from the crushing weight of debt anymore. Daniel Derksen, MD, a professor of public health at the Mel and Enid Zuckerman College of Public Health, said he's seen doctors in his state flock in greater numbers to places like Phoenix and Tucson, where the pay is greater.

Mask-wearing in childcare programs is linked with fewer COVID-19-related program closures, new data released suggest. Paloma Beamer, PhD, a professor in the Mel and Enid Zuckerman College of Public Health, has a 3-year-old son who wears masks at daycare and works closely with his school to train kids how to wear their masks.

Researchers have been looking to animal venoms for the next generation of antibiotics. Leslie Boyer, MD, associate professor at the College of Medicine – Tucson and medical director of the Arizona Poison Drug Information Center, who was not involved in the work, says the authors present convincing evidence for venom-dwelling microbes. But as a physician, she is skeptical that the microbes described in the paper have immediate clinical relevance.
