A group of infants and mothers tested at UT Arlington have given researchers another reason to extol the unique properties of breast milk.
A team led by Sandy Dasgupta, Jenkins Garrett Professor of Chemistry and Biochemistry, has found evidence that breast-fed babies can metabolize the environmental contaminant perchlorate, decreasing their risks of detrimental developmental effects from exposure.
The research suggests a link between this characteristic and bifidobacteria, bacteria that is plentiful in the digestive systems of breast-fed babies.
The team’s work with 18 pairs of infants and mothers is detailed in the article “Breast-fed Infants Metabolize Perchlorate,” which was recently accepted for publication by the American Chemical Society journal Environmental Science & Technology.
“Both Centers for Disease Control researchers and our lab have previously observed that there is a higher concentration of perchlorate in breast milk versus formula. Although the merits of breastfeeding far outweigh any risk posed by this, it has caused some mothers concern.” Dr. Dasgupta says. “Our results suggest that nature has already devised a way to at least partly take care of it.”

A UT Arlington multidisciplinary team has received a $360,000 grant from the National Science Foundation to build artificial nanopores made of silicon that can detect “bad molecules” as a very early indication of cancer and other diseases.
Samir Iqbal, an assistant professor of electrical engineering who focuses on nanotechnology, is leading the project. He works with Sandy Dasgupta, the Jenkins Garrett Professor of Chemistry and Biochemistry, and Richard Timmons, a Distinguished Professor of Chemistry.
Nanopores are tiny openings—about 1,000 times smaller than a human pore on the skin or a human hair—made in very thin silicon chips. The silicon chips are the same material in computer processors and memories.
Dr. Iqbal’s team will run human blood-derived samples through these artificially created nanopores in a silicon chip and record how the composition may change as a function of disease.

A team of University of Texas at Arlington researchers have developed a method that uses magnetic carbon nanoparticles to target and destroy cancer cells through laser therapy—a treatment they believe could be effective in cases of skin and other cancers without damaging surrounding healthy cells.
A paper about the work by Ali R. Koymen, professor of physics, and Samarendra Mohanty, assistant professor of physics, was published in January’s edition of the Journal of Biomedical Optics.
Ling Gu and Vijayalakshmi Vardarajan, two post-doctoral researchers in Dr. Mohanty’s lab, were coauthors on the paper “Magnetic-field-assisted photothermal therapy of cancer cells using Fe-doped carbon nanoparticles.”
Mohanty says the carbon nanoparticles can be coated to make them attach to cancer cells once they are positioned in an organ by the magnetic field. The magnetic carbon nanoparticles also are fluorescent, so they can be used to enhance contrast of optical imaging of tumors along with that of MRI.

Hear nursing researcher Judy LeFlore discusses her studies on virtual patients as training tools at the Focus on Faculty lecture at noon Wednesday, Feb. 29, in the sixth floor parlor of the Central Library.
Dr. LeFlore is an associate professor of nursing and director of pediatric, acute care pediatric, and neonatal nurse practitioner programs. Her topic is “Can Virtual-Patients Teach Student Nurses About Pediatric Respiratory Diseases?”
She and co-researcher Mindi Anderson, assistant professor of nursing, study the use of video game technology for nursing training. They were two of six authors awarded first place for their game proposal at the 11th Annual International Meeting on Simulation in Healthcare.
Qilian Liang, professor of electrical engineering, has received a $300,000 National Science Foundation grant to determine how much closer technology can push toward the upper boundary of a smart grid’s threshold.
Dr. Liang joined UT Arlington in 2002 and is working to marry electrical grid infrastructure with information technologies to transmit and distribute power closer to that threshold. The goal of the project is to determine the threshold and to figure out the roadmap toward that threshold.
One study conducted by the U.S. Department of Energy concludes that internal modernization could save between $46 billion and $117 billion in 20 years. A smart grid is a digitally enabled electrical grid that collects information about usage and demand then acts to improve the efficiency, reliability, and sustainability of electricity services.

The College of Nursing will use a $419,000 federal grant to bolster recruitment of minorities to its nursing Ph.D. program with hopes of addressing cultural disparities in health research and patient care.
The grant—a three-year award from the U.S. Department of Health and Human Services—will provide funds to recruit candidates from historically underrepresented groups and ensure the success of students through mentoring, professional socialization, and enhanced academic advising. Administrators believe their efforts will result in more students and graduates doing research related to disparities and provide more Ph.D.-prepared nurses to increase the number of minority faculty in nursing programs.
“The shortage of Ph.D.-prepared nurses is especially acute among minority nurses,” says Jennifer Gray, associate dean of the College of Nursing and principal investigator on the new grant. “As we have more and more minority patients seeking health care, we need minority health care providers who better understand their culture and could possibly be more effective.”
