ATLANTA - Physicians treating patients with shock should consider norepinephrine instead of dopamine as a tool for stabilizing blood pressure, according to an editorial in the March 4, 2010, issue of the New England Journal of Medicine (NEJM). Jerrold Levy, MD, FAHA, professor and deputy chair for research, Department of Anesthesiology, Emory University School of Medicine, and co-director of cardiothoracic anesthesiology, Emory Healthcare, authored the editorial. The editorial accompanies a...

Scientists have shown that cells' DNA-reading machinery can skim through certain kinds of damaged DNA without skipping any letters in the genetic "text." The studies, performed in bacteria, suggest a new mechanism that can allow bacteria to develop resistance to antibiotics. The results were published online this week in the Proceedings of the National Academy of Sciences. The senior author is Paul Doetsch, PhD, professor of biochemistry and radiation oncology at Emory University School of...

Ancient human teeth are telling secrets that may relate to modern-day health: Some stressful events that occurred early in development are linked to shorter life spans. "Prehistoric remains are providing strong, physical evidence that people who acquired tooth enamel defects while in the womb or early childhood tended to die earlier, even if they survived to adulthood," says Emory University anthropologist George Armelagos. Armelagos led a systematic review of defects in teeth enamel and...

Scientists at Emory University School of Medicine have discovered unexpected properties for a precursor to melatonin, the hormone that regulates sleep cycles. Melatonin is produced from the neurotransmitter serotonin in a daily rhythm that peaks at night. Melatonin's immediate precursor, N-acetylserotonin, was not previously thought to have effects separate from those of melatonin or serotonin. Now an Emory team has shown that N-acetylserotonin can stimulate the same circuits in the brain...

Draw a map of the brain when fear and anxiety are involved, and the amygdala"”the brain's almond-shaped center for panic and fight-or-flight responses"”looms large. But the amygdala doesn't do its job alone. Scientists at Emory University have recently built upon work from others, extending the fear map to part of the brain known as the prelimbic cortex. Researchers led by Kerry Ressler, MD, PhD, found that mice lacking a critical growth factor in the prelimbic cortex have trouble...

Emory University researchers believe they have come up with the cheapest, most efficient way yet to monitor adult mosquitoes and the deadly diseases they carry, from malaria to West Nile Virus. Emory has filed a provisional patent on the Prokopack mosquito aspirator, but the inventors have provided simple instructions for how to make it in the Journal of Medical Entomology. "This device has broad potential, not only for getting more accurate counts of mosquito populations, but for better...

Researchers at Emory University School of Medicine have determined the structures of two enzymes that customize histones, the spool-like proteins around which DNA coils inside the cell. The structures provide insight into how DNA's packaging is just as important and intricate as the information in the DNA itself, and how these enzymes are part of a system of inspectors making sure the packaging is in order. The results are published online this week in the journal Nature Structural and...

Model is expected to help researchers better understand social bonding and impairments to such behavior Researchers at the Yerkes National Primate Research Center, Emory University, have successfully generated the first transgenic prairie voles, an important step toward unlocking the genetic secrets of pair bonding. The future application of this technology will enable scientists to perform a host of genetic manipulations that will help identify the brain mechanisms of social bonding and...

The pedal-to-the-metal signals driving the growth of several types of cancer cells lead to a common switch governing the use of glucose, researchers at Winship Cancer Institute of Emory University have discovered. Scientists who study cancer have known for decades that cancer cells tend to consume more glucose, or blood sugar, than healthy cells. This tendency is known as the "Warburg effect," honoring discoverer Otto Warburg, a German biochemist who won the 1931 Nobel Prize in Medicine. Now...

Educating family members of heart failure (HF) patients about the health benefits of consuming a low-salt diet and providing skills for support and communication can effectively reduce HF patients' sodium consumption, according to an interdisciplinary study led by Emory University cardiovascular nursing researcher Sandra Dunbar, RN, DSN, FAAN, FAHA. Dunbar will present key findings of this study today at the annual meeting of the American Heart Association in Orlando. "Greater efforts are...

Sonny Carter was a physician, professional soccer player, naval officer, and NASA astronaut. He was born Manley Lanier Carter, Jr. on August 15, 1947 in Macon, Georgia. He graduated from Lanier High School in 1965 and then went to on study at Emory University, where he received a Bachelor of Arts degree in Chemistry in 1969. While at Emory, Carter played collegiate soccer and ran track. He was team captain and most valuable player of the soccer team during his senior season. In 1970, Carter...
