As part of the Fralin Undergraduate Research Fellowship, Tuhy is studying the formalin pain test, the most commonly used preclinical model to quantitatively evaluate inflammatory pain in rodents with minimal subjective input.

Songbirds exposed to lead-contaminated water show telltale signs about human impacts

Songbirds exposed to lead-contaminated water show telltale signs about human impacts Published Thursday, Feb. 4, 2021, 11:14 am Join AFP s 100,000+ followers on Facebook Purchase a subscription to AFP | Subscribe to AFP podcasts on iTunes News, press releases, letters to the editor: augustafreepress2@gmail.com (© Xavier MARCHANT – stock.adobe.com) Humans, wildlife, and the environment are all interconnected and play a role in one another’s health and well-being. Sentinel species, such as birds, are good indicators of environmental health, and they can send subtle warning signs that humans may be in danger next. In an experimental exposure study, Kendra Sewall, an associate professor of biological sciences in the College of Science, and a diverse team of scientists and students have found that lead levels like those reported in Flint, Michigan, can interfere with the neural mechanisms of vocal development of songbirds and affect mate attraction.

Study depicts previously unknown molecular mechanism underlying healthy brain development

Study depicts previously unknown molecular mechanism underlying healthy brain development A research team led by Michael Fox, a professor at the Fralin Biomedical Research Institute at VTC, has identified the type of brain cell that produces collagen 19, a protein that is crucial for the formation of inhibitory circuits in the brain. The study, published in the Journal of Neuroscience, depicts a previously unknown molecular mechanism underlying healthy brain development. This insight could one day help scientists establish the basis for developing new drugs that mature or repair cellular networks and mitigate disease. Neurons and glia are the most abundant types of brain cells. Glia, in particular star-shaped glia called astrocytes, release signaling molecules that support the growth and maintenance of healthy synapses, the chemical communication structures between neurons.
