HIV-infected patients are at a markedly increased risk for community acquired Methicillin-resistant Staphylococcus aureus (CA-MRSA) infections according to a new study by researchers at John H. Stroger, Jr. Hospital of Cook County and Rush University Medical Center.
The study, published in the April 1 issue of the journal Clinical Infectious Diseases, found the incidence of CA-MRSA in the Chicago area was six-fold higher among HIV-infected patients than it was among HIV-negative patients.
UC engineering researchers create tiny pools without walls with programmable microfluidic systems.
Microfluidic devices typically depend upon electrokinetic or traditional pressure methods to move microscopic amounts of fluid around a fixed microchip.
As just published as the cover story in "Lab on a Chip," in "Virtual electrowetting channels: electronic liquid transport with continuous channel functionality," engineering researchers at the University of Cincinnati have created a paradigm shift — and moved some tiny channels in the process.
ITHACA, NY. Were the twelve apostles guilty of overeating at the Last Supper? Two brothers—an eating behavior expert and a religious studies scholar—are publishing findings that might make you think twice at your Easter dinner.
In a first-of-its kind controlled experiment, researchers from the Boston University School of Public Health (BUSPH) and Brown University have found that surprisingly, binge drinking the night before a test does not impact college students' test performance – although it can affect their moods, attention and reaction times.
INDIANAPOLIS — Researchers have discovered how a genetic disease known mainly for its life-threatening tumors also can cause sudden death from cardiovascular disease in children, and are mounting a clinical trial to develop treatments for the problem.
PHILADELPHIA – Postmenopausal women who regularly use aspirin and other analgesics (known as painkillers) have lower estrogen levels, which could contribute to a decreased risk of breast or ovarian cancer.
"We observed some significant inverse associations between concentrations of several estrogens and the use of aspirin, aspirin plus non-aspirin nonsteroidal anti-inflammatory drugs (NSAIDs), and all analgesics combined," said Margaret A. Gates, Sc.D., research fellow at the Channing Laboratory at Brigham and Women's Hospital and Harvard Medical School.
DALLAS – March 23, 2010 – Human pancreatic cancer cells dramatically regress when treated with chemotherapy in combination with a synthetic compound that mimics the action of a naturally occurring "death-promoting" protein found in cells, researchers at UT Southwestern Medical Center have found.
The research, conducted in mice, appears in today's issue of Cancer Research and could lead to more effective therapies for pancreatic and possibly other cancers, the researchers said.
SAN FRANCISCO, March 23, 2010 — Scientists today described a new ultra-rapid acting mealtime insulin (AFREZZA™) that is orally inhaled for absorption via the lung. Because the insulin is absorbed so rapidly, AFREZZA's profile closely mimics the normal early insulin response seen in healthy individuals. AFREZZA is awaiting approval by the U. S. Food and Drug Administration (FDA). This presentation took place at the 239th American Chemical Society National Meeting, being held here this week.
Facelifts and other wrinkle-reducing procedures have long been sought by people wanting to ward off the signs of aging, but new research suggests that it takes more than tightening loose skin to restore a youthful look. A study by physicians at the University of Rochester Medical Center indicates that significant changes in facial bones – particularly the jaw bone – occur as people age and contribute to an aging appearance.
COLUMBUS, Ohio – Conventional wisdom among scientists for years has suggested that because individuals with Down syndrome have an extra chromosome, the disorder most likely results from the presence of too many genes or proteins contained in that additional structure.
But a recent study reveals that just the opposite could be true – that a deficiency of a protein in the brain of Down syndrome patients could contribute to the cognitive impairment and congenital heart defects that characterize the syndrome.
RUSTON, La – Professors Henry Cardenas and Sven Eklund, and Ph.D. candidate Kunal Kupwade-Patil of the College of Engineering and Science at Louisiana Tech University will present their award-winning paper at the Second International Conference on Sustainable Construction and Materials Technologies in Ancona, Italy, in June.
Measuring a set of protein changes in the blood linked to alcohol use may potentially lead to a more accurate diagnostic test than those currently available, according to Penn State College of Medicine researchers.
London, ON – A new study at The University of Western Ontario finds the sauces you use when firing up the barbecue this summer may provide unforeseen health benefits.
The research, led by Western biology and psychology postdoctoral fellow Raymond Thomas, shows common marinades may be more than just tasty sauces – they can also provide a major source of natural antioxidants. The paper was co-authored by Mark Bernards and Christopher Guglielmo in Western's department of biology.
Montreal, March 23, 2010 – Age and gender play a major role in how people respond to stress, according to a new study on 20-to-64-year-olds. Published in the journal Psychophysiology, the investigation was led by scientists from the Université de Montréal and the Montreal Heart Institute in collaboration with colleagues from the Université du Québec à Montréal and McGill University.
Feeling better about the future might help you feel better for real. In a new study, psychological scientists Suzanne Segerstrom of the University of Kentucky and Sandra Sephton of the University of Louisville studied how law students' expectations about the future affected their immune response. Their conclusions: Optimism may be good for your health.
