Chowdhury receives $354K NIH grant for protein research using mass spectrometry
A UT Arlington bio-analytical chemist exploring proteins, their structures and functions by using cutting-edge analytical instrumentation called mass spectrometry has received an Academic Research Enhancement Award from the National Institutes of Health.
The $354,749 in funding will help in identifying host-defense protein interactions networks caused by environmental and external agents.
Saiful Chowdhury, assistant professor in the Department of Chemistry and Biochemistry, is the principal investigator on the project. He is developing a mass spectrometry-based chemical cross-linking technology that will provide information on large-scale protein signaling networks in their natural biological conditions.
“Proteins reside inside and outside of the cells, and when we open the cells, most of the interaction information that can help us to better understand disease processes gets lost,” Chowdhury said. “Current biochemical methods are not very efficient to analyze system-level or large-scale protein interaction networks. Through innovative analytical techniques, and by chemical cross-linking of proteins before cell analysis, we can overcome current limitations.”

Mohanty team details new method of using optogenetics in the brain to control pain
A new study by a UT Arlington physics team in collaboration with bioengineering and psychology researchers shows for the first time how a small area of the brain can be optically stimulated to control pain.
Samarendra Mohanty, an assistant professor of physics, leads the Biophysics and Physiology Lab in the College of Science. He is co-author on a paper published online February 25 by the journal PLOS ONE.
Researchers found that by using specific frequency of light to modulate a very small region of the brain called the anterior cingulate cortex, or ACC, they could considerably lessen pain in laboratory mice. Existing electrode based ACC stimulation lacks specificity and leads to activation of both excitatory and inhibitory neurons.
“Our results clearly demonstrate, for the first time, that optogenetic stimulation of inhibitory neurons in ACC leads to decreased neuronal activity and a dramatic reduction of pain behavior,” Mohanty said. “Moreover, we confirmed optical modulation of specific electrophysiological responses from different neuronal units in the thalamus part of the brain, in response to particular types of pain-stimuli.”
The research focused on chemical irritants and mechanical pain, such as that experienced following a pinprick or pinch. Mohanty said the results could lead to increased understanding of pain pathways and strategies for managing chronic pain, which often leads to severe impairment of normal psychological and physical functions.

Photo highlights research by UT Arlington physicists about supernova remnant’s shape

A recent NASA news release and photo highlight a work published by Sangwook Park, assistant professor of physics, and Seth Post, a graduate student in physics, which studies the shape of a Type 1a supernova remnant using data collected by NASA’s Chandra X-ray observatory.
The paper by Park and Post, along with six co-authors from around the world, appeared in the Sept. 1, 2014, issue of The Astrophysical Journal. The scientists’ findings suggest that a very lopsided explosion may have produced the supernova remnant, which is named G299.2-2.9 (G299 for short) and is located within the Milky Way galaxy.
Type Ia supernovas have long been known to be uniform in their extreme brightness, the NASA news release said. This is important because scientists use these objects to accurately measure the distances of galaxies billions of light years away, and to determine the rate of expansion of the Universe. Traditional theoretical models of Type Ia supernovas generally predict that these explosions would be symmetric, creating a near perfect sphere as they expand. These models have been supported by results showing that remnants of Type Ia supernovas are more symmetric than remnants of supernovas involving the collapse of massive stars, according to the NASA release.
However, astronomers are discovering that some Type Ia supernova explosions may not be as symmetric as previously thought. G299 could be an example of such an "unusual" Type Ia supernova. Using a long observation from Chandra, the researchers discovered the shell of debris from the exploded star is expanding differently in various directions.
