New anti-blood-thinning drug not as safe as protamine
The results of an international clinical trial led by Duke University Medical Center researchers has shown that a new drug is not a suitable replacement for protamine, a drug that has been used for more than 40 years after coronary artery bypass surgery to return thinned blood to its normal state. view more (2005-08-01)
Women may be able to 'take break' from osteoporosis drug without losing benefit
Most postmenopausal women who took the osteoporosis drug alendronate for 5 years and then stopped did not have an increased risk for nonvertebral fractures in the next 5 years, suggesting the medication has a lasting effect, according to a study in the December 27 issue of JAMA. view more (2006-12-27)
Plastic and reconstructive surgery ... in brief
New web-based research has quantified the attractiveness of the female form. Using morphing software, German researchers manipulated the features of one woman into 243 variations with differing leg lengths, weights, bust sizes, and hip and waist widths. view more (2009-02-27)
Problem: Implant Infection. Solution: Nanotech Surfaces
Orthopaedic implants help millions of Americans stay active. But these medical devices are prone to infection, forcing patients back to surgery for repair or replacement. Now, for the first time, a team of engineers has shown that zinc or titanium oxide nanosurfaces can reduce the presence of bacteria, a technique that can be applied to implants... view more...

BUSM researchers propose a relationship between androgen deficiency and cardiovascular disease
Researchers from Boston University School of Medicine (BUSM) in collaboration with researchers from Lahey Clinic Northshore, Peabody, Mass., believe that androgen deficiency might be the underlying cause for a variety of common clinical conditions, including diabetes, erectile dysfunction, metabolic syndrome and cardiovascular disease (CVD). view more (2009-09-28)
Retrospective study analyzes expenses of osteoporosis-related fracture over 3 years
In a retrospective analysis of more than 30,000 female Medicare patients 65 years and older, osteoporosis fractures resulted in fracture-related medical expenses of $15,522 per person over three years. view more (2008-09-15)
Mayo Clinic discovers DNA repair as key to Huntington's disease
Mayo Clinic researchers, along with collaborators from the National Institutes of Health (NIH) and University of Oslo, Norway, have discovered that a miscue of the body's genetic repair system may cause Huntington's disease, a fatal condition that affects 30,000 Americans annually by destroying their nervous system. view more (2007-04-23)

Microwires: replacement for the CD-ROM?
A ballpoint that detects if we are forging a signature or a substitute in miniature for the CD-ROM are some of the applications that can be carried out using microwires. view more (2005-03-07)
Stem cells found in adult hair follicles may provide alternative to embryonic stem cells
Having recently identified the molecular signature of these epidermal neural crest stem cells in the mouse, their research resolves conflicting scientific opinions by showing that these cells are distinctly different from other types of skin-resident stem cells/progenitors. Their work provides a valuable resource for future mouse neural crest stem... view more... (2006-12-12)
Fitness counteracts cognitive decline from hormone-replacement therapy
Women pondering hormone-replacement therapy also should consider regular exercise. A new study at the University of Illinois at Urbana-Champaign suggests that being physically fit offsets cognitive declines attributed to long-term therapy. view more (2006-01-25)
Pituitary hormone implicated in bone loss after menopause
New evidence in the April 21, 2006 Cell challenges the long-standing notion that declining estrogen levels alone lead to osteoporosis after women go through menopause. view more (2006-04-21)
UW scientists one step closer to stopping bone loss during spaceflight
Bone loss in long-duration spaceflight has been identified for decades as a significant problem affecting astronauts. More recently, scientists have found that the absence of gravity is causing astronauts on the International Space Station to lose up to 10 times more bone mass in key regions of the body each month than most post-menopausal women... view more...

Adiponectin is a metabolic link between obesity and bone mineral density
Researchers at the University of Toronto, Faculty of Medicine, Toronto, Canada, have discovered that adiponectin, a protein secreted from adipocytes, is a metabolic link that can explain, in part, the known positive relationship between obesity and both bone mineral density and reduced susceptibility to fractures. view more (2008-11-26)
Cancer risk slightly higher for women in discontinued hormone treatment trial
A follow up study of participants in the Women's Health Initiative (WHI) clinical trial led by a University of North Carolina at Chapel Hill researcher has found that women who were taking the combined hormone therapy of estrogen plus progestin may have an increased risk of cancer since the intervention was stopped, compared to participants in the... view more...

HIV study prompts call for revision of breastfeeding guidelines
A study by scientists at the Africa Centre for Health and Population Studies, South Africa, has shown that exclusive breastfeeding can significantly reduce the risk of HIV transmission from mother to child in infants aged under six months when compared to those also given solid foods or replacement feed (i.e. formula milk). view more (2007-03-30)
Mice roar message: genetic change happens fast
While looks can be deceiving, heredity is revealing, and two scientists who've studied the genetic makeup of a common field mouse report that what's most revealing to them is how fast both genes and morphology can change. view more (2007-10-22)
Dental implants preferred option for aging bridges
Aging dental bridges are a maintenance headache and a recipe for oral-health disaster. They are difficult to floss, often decay, and require replacement with longer bridges. According to the American Academy of Implant Dentistry (AAID), these bridges to nowhere should be replaced with permanent dental implants. view more (2008-05-30)
World first research to speed up cure for ear infections
Fast tracking the healing process for common ear infections will be the focus of ground-breaking research by WA's Lions Ear and Hearing Institute (LEHI). view more (2006-04-19)
