Vik named 2008 SMU Ford Research Fellow

vik.jpgSteven Vik, in the Department of Biological Sciences of Dedman College, has received an SMU 2008 Ford Research Fellowship.

A professor in the Department of Biological Sciences, Vik’s research interests include protein structure and function, and the biochemistry of membrane-bound enzymes. His work focuses on key mechanisms of bioenergetics, the study of how living systems get and use the energy sources required to sustain life.

Vik has made significant contributions to the understanding of the key enzyme in these processes, the ATP synthase.

He was the first to correctly deduce the internal mechanisms of how the movement of charged ions across a biological membrane coupled with the ATP synthase’s rotary mechanism produce adenosine triphosphate, ATP, which is essential for nerve functioning, muscular and molecular movement and other vital cellular processes.

Vik is a member of the editorial board of the “Journal of Biological Chemistry.”

Medical Tourism: Risky business to seek cheaper health care

More and more Americans are choosing to receive medical treatment — even complicated surgeries — in foreign countries to save big money. The practice is called “medical tourism,” but do the risks to consumers outweigh the savings?

That’s an important question, says Nathan Cortez, SMU Dedman School of Law assistant professor, who is focusing his research in health law on this emerging medical market.

“Patients take a calculated risk by seeking medical care overseas in regulatory systems that may not offer the rights or protections they expect,” Cortez says.

Interviewed for National Public Radio last November, he warned that although patients are free to travel overseas and reap whatever savings they can find, the international shop-around could affect how U.S. hospitals pay for care for the uninsured.

“We see this all the time with other industries,” Cortez told NPR. “Health care has been notoriously a local industry, and now it’s … succumbing to globalization like other industries have.”

Cortez has published the first comprehensive look at how domestic policy-making can offer American medical tourists some level of consumer protection. “Patients Without Borders: The Emerging Global Market for Patients and the Evolution of Modern Health Care” is included in the winter 2008 issue of the “Indiana Law Journal.”

Attempts to restrict patient travel may not be effective, Cortez warns. But he offers some practical approaches to help protect American patients: Regulating the activities of brokers and others who arrange for U.S. patients to travel overseas could provide access to information about the quality of care outside the United States.

Lawmakers could require employers or insurers that encourage patients to have surgery overseas to pay for pre-screening and post-operative care in the United States.

Lawmakers could require employers to share a minimum portion of the cost savings with patients willing to have surgery overseas, which would partially compensate them for any additional risk they may bear.

Although lowering the cost of medical care is a universal concern, Cortez says there is no evidence of American employers requiring employees to seek cross-border treatment. But neither are cost-conscious companies who are quietly adding foreign hospitals to their provider networks seeking publicity for those additions.

“California is the only state where you can buy insurance plans that require treatment outside the United States,” Cortez says. “It’s a niche market for the immigrant population there — you agree to go to Mexico.”

Cortez was a featured speaker at a March symposium on cross-border health care hosted by the Wisconsin International Law Journal, and is conducting research for that publication on the underlying trends that encourage medical tourism.

“I argue that the practices and standards in the medical industry are becoming more similar across borders, which makes medical tourism possible,” Cortez says.

Cortez teaches courses in administrative law, health law, FDA law and the legislative process. Before joining SMU in fall 2007, he practiced with the Washington, D.C., firm of Arnold & Porter representing medical technology clients, with a special emphasis on health care fraud and abuse, FDA enforcement and health privacy. He earned a J.D. from Stanford.

SMU is a nationally ranked private university in Dallas founded 100 years ago. Today, SMU enrolls nearly 11,000 students who benefit from the academic opportunities and international reach of seven degree-granting schools. For more information see www.smu.edu.

Ethiopian fossils to shed light on climate change

Crew2007-2008-sm.jpgA team of researchers led by paleobotanist Bonnie Jacobs and sedimentologist Neil Tabor of Southern Methodist University returned to northwestern Ethiopia in late December 2007 to spend almost a month collecting additional plant fossils and gaining a more thorough understanding of their geological context.

In December 2006, the team collected more than 600 plant fossils, which are on loan for study in labs at SMU’s Roy M. Huffington Department of Earth Sciences in Dedman College. All told, the team has documented more than 1,500 plant fossils, hundreds of vertebrate fossils and numerous examples of ancient soils. This year they widen their search to better understand the geology, landscape, plant and animal communities, and climate of Chilga, Ethiopia, 28 million years ago.

The project, which also is training Ethiopian students in geology and paleontology, is funded by a $300,000, three-year grant from the National Science Foundation.

In this second year of the grant period, the team will collect from a fruit and seed deposit — to compare with that collected last year — sample leaves to provide information about insect plant-eaters, and explore for new fossil sites, according to Jacobs, associate professor, and Tabor, assistant professor, both in the Department of Earth Sciences.

The 2007-2008 Ethiopia crew

The project is expected to help scientists understand the world’s changing climate, by knowing about that of the past based upon plant fossils and ancient soils.

Documenting past climate at low latitudes, including in Africa, helps researchers understand global climate change. In addition, the early origins of Africa’s flora are largely a mystery. What we know comes primarily from hypotheses generated by the modern distributions of plants rather than from the fossil record.

Angiosperms, “flowering plants,” make up nearly all living plants in today’s tropical, subtropical and temperate regions. In Africa, little is known about how they changed and adapted between their evolutionary origins 130 million years ago and recent times. Chilga fossils provide a unique view of the Earth’s plant life 28 million years ago, and fill a gap in understanding the evolution of today’s tropical floras.

The 2006 effort focused on, CH-3, which was known to produce both plant and vertebrate fossils. Until last year, only 92 plant specimens had been collected from CH-3 and these all came from the surface. These are usually bigger, less delicate specimens because they’ve been exposed to erosion and perhaps moved from their original position in the sediment.

The researchers excavated into the hillside at CH-3, exposing the fossiliferous deposit and, after only eight days, collected 523 specimens — mainly fruits and seeds. Their finds included some things never seen before at Chilga, such as several flowers, some very tiny seeds, and a large fruit, all of which are still being studied.

Besides Jacobs and Tabor, the 2007 team included: SMU students Dan Danehy and Harvey Herr; John Kappelman, University of Texas at Austin; and Ellen Currano, Penn State University.
