March 4, 2013 | With hors d’oeuvres and a relaxed atmosphere, the University of Arkansas for Medical Sciences (UAMS) took a second swipe Feb. 27 at knocking down the barriers between medical researchers and their academic disciplines.

UAMS research scientists and physicians gathered for “The Showcase of Medical Discoveries: A Focus on Nanomedicine,” the second of an ongoing series. The first showcase was in November and focused on cardiovascular research on campus. Both were sponsored by the UAMS College of Medicine to give the college’s research scientists the opportunity to discuss their findings with each other, donors and interested students and faculty.

“This is a good exposure,” said William Culp, M.D., professor in the UAMS College of Medicine’s Department of Radiology. “I was only aware of about a third of what’s up here. This is a good thing for the faculty to find out what other faculty are doing.”

Like the representatives of 10 other research teams standing before large posters summarizing their projects, Culp talked with several of the 100 people at the gathering in the rotunda of the Winthrop P. Rockefeller Cancer Institute. He was part of a group looking for potential ways to use nanomedicine to protect stroke patients from neurological damage.

The idea for the showcase grew out of a series of roundtable discussions Debra Fiser, M.D., dean of the UAMS College of Medicine, and Lawrence Cornett, Ph.D., vice chancellor of research, had with College of Medicine faculty. Each discussion group involved 10-12 faculty members, and nearly every group expressed a desire for more opportunities to interact with fellow faculty members on a social basis regarding their scientific work.

At the February showcase, Fiser said the first goal of the events is to foster a spirit of collaboration among research teams, and the second goal is to introduce to its researchers people who are actively involved at UAMS and donors.

“In some cases, they are people who haven’t donated to research but have a general interest in science or in the area and want to know more,” Fiser said. “The feedback we’ve gotten from attendees has been very positive. They’ve said this is something that is fascinating to them, and they have enjoyed interacting directly with the scientists.”

One of the researchers at the February showcase was among the many who said he enjoyed the interaction.

“You can’t be a scientist without absolute commitment,” said Mark Smeltzer, Ph.D., professor in the College of Medicine’s Department of Microbiology and Immunology. “If you’re committed to that, then why would you not want to talk about it?”

Smeltzer’s research is exploring the use of nanotechnology to fight bacteria, particularly Staphylococcus aureus. The showcases give researchers a chance to learn more about how others are using the technology

Cornett said because the feedback has been positive and the turnout good at both events, it is likely there will be more showcase events later this year.

Posters at the showcase, using text and graphics, described the work of many different research project groups that include dozens of basic and clinical scientists as well as trainees. They were:
