Deimund Nominated for Marshall Scholarship

Posted in Student on Monday, November 9th, 2009

COLLEGE STATION, Nov. 9, 2009 – Mark Deimund, a senior in the Artie McFerrin Department of Chemical Engineering, has been nominated for the Marshall Scholarship, one of the two most prestigious and highly coveted academic scholarships available to United States students.

Deimund, class of 2010, is from Oklahoma City. The president of Texas A&M University’s American Institute of Chemical Engineers chapter, his recent research on biomass processing has garnered him a patent, and his current research involves systems biology in liver cells. He also is an avid strength trainer and enjoys classical literature. If selected as a Marshall Scholar, Deimund said he will study advanced chemical engineering at Cambridge University. He said he will also apply for the Winston Churchill Foundation Scholarship and the Gates-Cambridge Scholarship.

Deimund was recently named a 2009 recipient of the Craig C. Brown Outstanding Senior Award from the Dwight Look College of Engineering.

The Marshall Scholarship is tenable for two years of study at any university in the United Kingdom. Students must be graduating seniors or recent graduates and be nominated by the university. Hundreds of students from across the United States apply each year; only 40 of the approximately 1,100 who applied for the Marshall Scholarship in 2008 were selected as scholars.

Nominees will hear of their selection as finalists in the next one to two weeks. Finalists will then participate in regional or district interviews in Houston in November. The announcement of scholars will be announced shortly thereafter.

Texas A&M University has produced four Marshall Scholars, the most recent being Faye Hays in 2007. In the 2009 competition, biochemistry major Matthew Hickey was a finalist for the Marshall.

The Marshall Scholarships began in 1953 as a gesture of thanks from the British Government for U.S. assistance in rebuilding Europe after World War II. Former Marshall Scholars include Supreme Court Justice Stephen Breyer and New York Times Foreign Affairs columnist Thomas Friedman. According to the Marshall Scholarship Foundation, as future leaders, Marshall Scholars are “expected to strengthen the enduring relationship between the British and American peoples, their governments and their institutions. Marshall Scholars are talented, independent and wide-ranging, and their time as scholars enhances their intellectual and personal growth. Their direct engagement with Britain through its best academic programms contributes to their ultimate personal success.”

Because of the fierce competition for these scholarships, the preliminary process to be selected as an official university nominee is quite rigorous. Currently enrolled students and recent graduates should apply for selection in April, with the official deadline for the scholarships being in early October. To be awarded the university’s nomination, a student must show strong scholarly potential, demonstrated through their academic record and letters of recommendation from faculty, leadership ability, demonstrated through their involvement in student and civic organizations, and excellent speaking and analytical skills, as demonstrated in a series of interviews.

Once approved, prospective nominees can expect to spend months developing their applications as they work closely under the advice and guidance of faculty and academic advisors. The official announcement of university endorsement is made only after the nominees submit their finalized application to the scholarship foundations.

The SEF seeks collaborative work in programming and education objectives with other professional societies, both national and foreign. Specific focus areas of the forum include using appropriate metrics for sustainability; developing approaches for designing products and processes that can be optimized to desired metrics criteria and that incorporate environmental and societal benefit factors; and assessing impacts of resource use on environmental and social benefits of products, processes and services.

Other focus areas include designing new processes or products that are comparatively benign; responding to socioeconomic measures such as emission trading; and developing educational materials related to the field.

El-Halwagi will receive the award at an awards ceremony taking place during the 2009 AIChE Annual Meeting in Nashville.

Research Examines How Infections Begin in Human GI Tract

Posted in Department on Thursday, November 5th, 2009

COLLEGE STATION, Texas, Nov. 5, 2009 – Understanding how certain pathogenic bacteria strains such as E. coli cause infection in people begins with unraveling the complex “talk” between the trillions of cells living in the human gastrointestinal (GI) tract, says Arul Jayaraman, a Texas A&M University researcher who has developed an artificial system that mimics the unique bacteria-laden environment of the human GI tract.

The system is detailed this month in “Lab on a Chip,” a scientific journal published by the Royal Society of Chemistry – the largest organization in Europe for advancing the chemical sciences.

It represents a significant step in understanding bacterial interactions in the GI tract because it accurately simulates conditions within that area by enabling human epithelial cells to grow in balance with the naturally occurring bacteria (termed “commensal”) that reside in the GI tract.

Traditionally, growing both types of these cells simultaneously in a laboratory environment has been difficult because bacteria reproduce at a much faster rate than epithelial cells and tend to monopolize the nutrients needed by the epithelial cells, says Jayaraman, assistant professor in Texas A&M’s Artie McFerrin Department of Chemical Engineering.

“If you try to achieve this in a cell-culture dish what happens is that you have a very nutrient-rich environment that bacteria basically thrive in, dividing rapidly,” Jayaraman says. “You can start with the same number of cells, relatively in proportion, but the bacteria will keep dividing, taking up all of the nutrients. Epithelial cells then do not get what they need. They are typically more finicky than bacterial cells. The numbers then kick in, and it is an exponential process where you will soon have millions of bacteria outnumbering epithelial cells, which will soon die.”

That doesn’t happen in Jayaraman’s model, which grows the epithelial and commensal cell colonies separately before allowing them to interact as they would in the gut. Once the two types of cells are interacting in the right balance, Jayaraman can recreate the sequence of events in a GI tract infection by introducing a foreign pathogen – in this case, Enterohemorrhagic E. coli – to the cells within his model.

Previous studies have just added pathogenic bacteria into colonies of endothelial cells, but this approach does not replicate the cellular interactions and chemical signals present in the human GI tract, Jayaraman notes.

“If you really want to understand how the commensal bacteria that are in the GI tract either prevent or enhance infection, you need to have a way in which you can actually recreate the system with both components present – the commensal cells and the epithelial cells,” Jayaraman says. “To our knowledge, this is the first report describing co-culture of bacteria and epithelial cells and its application to investigate pathogen colonization and infection.”

Commensal bacteria, he explains, produce a wide range of bacterial signals, and the concentration of these signals in the GI tract is extremely high.

These signals, he adds, are given off during normal metabolic processes of the cells. While there is no evidence to suggest that they were created specifically for defensive purposes, some of these signals have evolved to act as a line of defense. Others may actually enhance a pathogen’s infectious potential, he says. For the invading pathogen, it’s a matter of “talking” to the right cells and avoiding the “wrong” ones.

It’s a game of “push and pull” that is further complicated by the fact that the strength of these signal levels varies, Jayaraman says. For example, a person may be under a lot of stress, which can cause stress hormones to be high and might in turn diminish the signals that aid in defense against a pathogen. Other times, a gastric disease might kill some of these cells that are emitting a protective signal, lowering the overall strength of the signal and making a person more susceptible to serious infection, Jayaraman notes.

So far, Jayaraman’s model has yielded some interesting findings, shedding light on the constant array of signals being emitted within the GI tract and their effects on invading pathogens. One of those findings reveals how indole, a chemical produced by commensal cells within the GI tract, acts a signal to foreign pathogens.

“Indole already has been shown as an important signal for communication between bacteria,” Jayaraman says. “We are looking at how pathogens might also be affected by indole, and we are seeing that they are indeed affected.”

Specifically, if a pathogen passes through bacteria that produce indole, the pathogen will become less infectious, Jayaraman explains. Conversely, if it passes through bacteria where there is no indole, the pathogen retains it same degree of virulence.

“In a sense, the pathogen is looking for weak points in a ‘wall’ of defense,” Jayaraman says. “We believe this can be applied to several other signals. There might be signals that increase a pathogen’s infectiousness. Does it choose a location in the wall where it can pass through without decreasing its infectious potential, or does it look for a place where its infectiousness is enhanced?”
