Bone quality regulator identified - possible target for preventing and treating bone fractures

University of California - San Francisco (UCSF) scientists have determined that the quality of bone matrix, a key component of bone, is regulated by a molecule known as transforming growth factor beta.

Risedronate prevents bone loss and periodontal disease

Drugs that reverse and prevent bone loss due to osteoporosis also significantly ward off periodontal disease, according to a graduate of the Case Western Reserve University School of Dental Medicine who reports in the current Menopause journal article, "Periodontal Assessments of Postmenopausal Women Receiving Risedronate."

Breast CT may be better than mammography at detecting breast lesions

Breast CT, an investigational technology for early breast cancer detection, may be better than mammography at detecting breast lesions and is much more comfortable for women, researchers from the University of California, Davis reported at the annual meeting of the Radiological Society of North America in Chicago.

Researchers gain detailed view yet of the heart of the translocon

Researchers have gained the most detailed view yet of the heart of the translocon, a channel through which newly constructed proteins are inserted into the cell membrane. The process of transporting proteins across or into membranes is a critical function that occurs in every cell.

Ultrasound to view heart's interior in three dimensions

Duke University engineers are developing technology that may enable physicians to someday use high frequency ultrasound waves both to visualize the heart's interior in three dimensions and then selectively destroy heart tissue with heat to correct arrhythmias.

New high-resolution data on intact ribosome

A new, sharper picture of the nano-machine that translates our genetic program into proteins promises to help researchers explain how some types of antibiotics work and could lead to the design of better ones.

Molecule called metallacarborane appears to fight HIV protease

A molecule consisting of two "cages" of metallic atoms bound to carbon has shown great promise in preliminary tests of becoming a new weapon in the anti-HIV arsenal, researchers at UT Southwestern Medical Center report.

Breast magnetic resonance imaging helps doctors select best treatment for early breast cancers

Breast magnetic resonance imaging enhances patient selection for accelerated, partial breast irradiation by detecting previously unsuspected, microscopic lesions within the breast, according to a study presented October 17, 2005, at the American Society for Therapeutic Radiology and Oncology's 47th Annual Meeting in Denver.

Research points way to more effective delivery of medicine around the body

New research showing how drugs stick to a key protein in the bloodstream could help to create drugs that are delivered more effectively to organs in the body.

Fijiian seaweed shows potential to kill cancer cells, bacteria and the HIV virus

Researchers have discovered 10 new molecular structures with pharmaceutical potential in a species of red seaweed that lives in the shallow coral reef along the coastline of Fiji in the south Pacific Ocean.

Electron-beam computed tomography - a more accurate replacement for coronary catheterizations

Electron-beam computed tomography (EBCT) is more accurate than conventional catheter angiography for detecting a dangerous congenital heart abnormality that could cause sudden death, according to research by a Saint Louis University radiologist published last month in Catheterization and Cardiovascular Interventions: Journal of the Society for Cardiovascular Angiography and Interventions.

Researchers reveal basis for hereditary coproporphyria

A research team led by scientists at The University of Texas Medical School at Houston has determined the structure of an enzyme that when defective causes an inherited disease that afflicts sufferers with severe abdominal pain, psychiatric symptoms, skin fragility, and light sensitivity.

PACs should not be used routinely in patients in intensive care units with severe heart failure

The use of a pulmonary artery catheter (PAC) -- a device used for more than 30 years to assess cardiovascular health and to help guide the treatment of critically ill patients -- does not appear to improve outcomes nor confer added risks to patients.

Researchers "should rethink what they are doing" in creating drugs based on a fruit-fly model

The first close-up look at a pro-inflammatory signaling molecule involved in immune response in mammals suggests that researchers "should rethink what they are doing" in creating drugs based on a fruit-fly model, scientists say.

Discovery may lead to development of more effective antibiotics

Researchers at the Georgia Institute of Technology and the John Innes Centre in the United Kingdom have uncovered a mechanism with which disease-causing bacteria may thwart the body's natural defense responses. The findings, which could ultimately lead to the development of more effective antibiotics, appear in the September 29, 2005 issue of the journal Nature.

Digital mammography and breast cancer in older women

Digital mammography that uses computers to detect breast cancer found significantly (up to 28%) more cancers than screen film mammography in women 50 and younger, premenopausal and perimenopausal women, and women with dense breasts, according to results from one of the largest breast cancer screening studies ever performed.

Still a long way to go in diagnostic evaluation of all patients who suffer ischemic strokes

Women who survive a stroke are less likely than men to get crucial tests of their heart and neck arteries that can help improve their treatment and reduce their risk of a second stroke, a new University of Michigan study finds.

New treatment option for chronic sinusitis

Acclarent on Saturday unveiled their new treatment option for chronic sinusitis, the Balloon Sinuplasty procedure. Results from the initial safety and feasibility study of this unique, catheter-based treatment for chronic sinusitis were presented by William Bolger, MD, FACS.

Daylight savings changes may help extend the life and health of people's teeth and bones

Beginning in 2007, daylight savings time will be extended by almost a month. This additional amount of daylight may also help extend the life and health of people's teeth and bones. That's because vitamin D, also known as the "sunshine vitamin," is made by the body through casual and minimal sun exposure.
