What the researchers identified is a specific protein "signal" that appears to prevent neural stem cells -- the sort that might be used to rebuild a damaged nervous system -- from taking their first step toward becoming neurons. "Stem cells don’t instantly convert into functional adult tissue," says author Nicholas ...

“In order to be best protected against HPV, teens need all three shots before they are exposed to the virus,” said Cynthia Rand, M.D., M.P.H., assistant professor of Pediatrics at the University of Rochester Medical Center, and author of a study in Pediatrics today about adolescents’ need for more doctor ...
In a study that appears in the October issue of the Journal of General Internal Medicine, they evaluate the usefulness of a scale that asks patients in primary care to rate their current pain from 0 (no pain) to 10 (worst pain). Universal pain screening is an increasingly common ...
"Previous inconsistencies could be due to a variety of sources, including differences in the symptom profiles of alcoholics who have participated in various studies, and/or methodological limitations of previous studies," explained Danielle Dick, corresponding author for the study. "If individuals are not carefully matched, and/or differ on other characteristics such ...
Eva Harth (Credit: photo by Neil Brake) Eva Harth is tackling the second part of this problem. She is creating a modular, multi-functional drug delivery system that promises simultaneously to enhance the effectiveness and reduce undesirable side-effects of a number of different drugs. Harth, who ...
"There is a strong correlation between dairy consumption and calcium," says Sibylle Kranz, assistant professor of nutritional sciences. "While there is calcium in fortified orange juice, for example, it is not as bioavailable as that found in milk." She notes that people need to take calcium with vitamin D ...
AMD results in partial or total blindness in 7 to 15% of the elderly, according to the Eye Diseases Prevalence Research Group. "Dietary changes may be the most practical and cost-effective prevention method to combat progression of AMD," says Allen Taylor, PhD, director of the Laboratory for Nutrition and Vision ...

During the procedure, a radiologist uses a needle to insert a small radioactive seed, about the size of a grain of rice, into the mass. Once lodged, surgeons use a wand that detects radioactivity to locate the mass and find the best pathway for removal. "The new technique is less invasive ...
“This ethnic difference in blood pressure dipping may help explain why African Americans are at greater risk of hypertension,” says Dr. Joel Hughes, Kent State assistant professor of psychology, “as a smaller dip in nighttime blood pressure has been associated with increased left ventricular mass and wall thickness in the ...
"Continuous positive airway pressure, or CPAP, is a well-established treatment for sleep apnea," said lead study author Akram Khan, MD, Assistant Professor, University of Florida Jacksonville, "and while most patients tolerate it well, some are unable to tolerate it or don’t want to, and those patients need alternative means of ...
Michael Frank, an assistant professor of psychology and director of the Laboratory for Neural Computation and Cognition at The University of Arizona, and his research colleagues have shed some light on how DBS interferes with the brain’s innate ability to deliberate on complicated decisions. DBS implants affect the region of ...
"Zinc plays a critical role in our bodies functioning properly," said Dr. Min Li, assistant professor of the Michael E. DeBakey Department of Surgery at BCM, and lead author of the study. "Zinc must be regulated through proteins called zinc transporters to keep us healthy." A previous study by one of ...
"We’ve always known personal income and education can affect one’s health outcomes," says Esme Fuller-Thomson, study co-author and assistant professor of social work at the Factor-Inwentash Faculty of Social Work at U of T. "What we didn’t know until now was the substantial strength of the relationship between state-level ...
"Several studies have found that peer drinking has more of an influence on an adolescent’s drinking than his or her own parent’s drinking," said Danielle Dick, corresponding author for the study. Now at Virginia Commonwealth University, Dick was an assistant professor at Washington University, St. Louis when this study ...
All participants in the study wore pedometers and received automated weekly goals that were based on their previous week’s walking activity. For half of the participants these goals were "lifestyle goals," meaning that any step taken during the day counted. The other half received "structured goals," in which only steps ...
MIT scientists report that adult stem cells produced in the brain are pre-programmed to make only certain kinds of connections- - making it impossible for a neural stem cell originating in the brain to be transplanted to the spinal cord, for instance, to take over functions for damaged cells. Some researchers ...
The study, led by radiologist Julie Song, M.D., examined 973 patients with 1,049 adrenal masses in order to describe the prevalence of pathology in adrenal masses incidentally identified on CT. According to the study, 1,045 of the 1,049 adrenal masses were confirmed to be benign and clinically insignificant. The study ...
In the first-ever study of its kind, U of T researchers Dr. Kumanan Wilson and Dr. Jennifer Keelan analyzed 153 videos about vaccination and immunization on YouTube, a popular online video-sharing site. Researchers found that more than half of the videos portrayed childhood, HPV, flu and other vaccinations negatively or ...
Meanwhile, most overweight women don’t want to be thin enough to achieve a healthy weight. According to the study, one of the few to quantify the magnitude of body-weight dissatisfaction, which was published recently in the journal Eating Behaviors, most -- 78 percent -- of the overweight males surveyed also want ...

The new research from the University of Michigan School of Public Health and the Arbor Research Collaborative for Health found that high out-of-pocket drug costs are only a partial reason why fewer American dialysis patients took their medications than in other countries, said Richard Hirth, professor at the U-M School ...
"If this is translatable to people, it could be really exciting," says Andrew Feinberg, M.D., professor of medicine, oncology and molecular biology and genetics and director of the Epigenetics Center at Hopkins. "It means we might be able to do something about at-risk cells before cancer develops, and treat these ...
What’s more, in several instances, re-introducing repressed miRNAs into Myc-containing cancer cells suppressed tumor growth in mice, raising the possibility that a sort-of gene therapy approach could be effective therapy for treating certain cancers. A research team led by Joshua Mendell, M.D., Ph.D., assistant professor at the McKusick-Nathans Institute of Genetic ...
"Rifapentine is back," says Johns Hopkins infectious disease specialist Eric Nuermberger, M.D., whose studies in mice, to be published in the Public Library of Science journal PLoS Medicine online Dec. 17, have found it so promising as an initial treatment for active TB that clinical trials are scheduled to begin ...
“Patients who received care from a geriatrician tend to have better prescribing and they tend not to receive drugs that are inappropriate for older patients,” said Mary Jo Pugh, Ph.D., the study’s lead author. That is because geriatricians are trained to “take a much closer look at the medications than the ...
