$High-trauma fractures in older adults linked to osteoporosis, increased risk of another fracture$

High-trauma fractures in older adults linked to osteoporosis, increased risk of another fracture

Contrary to a widely held assumption, high-trauma nonspine fractures in older women and men, such as from a car crash, are associated with low bone mineral density and an increased risk of a subsequent fracture, according to a study in the November 28 issue of JAMA.

$Factors identified to predict hip fracture in postmenopausal women$

Factors identified to predict hip fracture in postmenopausal women

A clinical model that includes 11 factors has been developed to help predict the 5-year risk of hip fracture in postmenopausal women, according to a study in the November 28 issue of JAMA.

$Model provides risk factors for hip fractures in older women$

Model provides risk factors for hip fractures in older women

Experts say there are around 329,000 hip fractures in postmenopausal women in the United States each year and up to 24% of hip fracture patients over 50 die within one year of the injury because of complications related to the injury itself or the extended recovery period.

Scientists bridge the "terahertz gap"

Going through airport security can be such a hassle. Shoes, laptops, toothpastes, watches and belts all get taken off, taken out, scanned, examined, handled and repacked. But "T-rays", a completely safe form of electromagnetic radiation, may reshape not only airport screening procedures but also medical imaging practices.

Premenopausal women with depression have less bone mass

Premenopausal women with even mild depression have less bone mass than do their nondepressed peers, a study funded in part by the National Institute of Mental Health (NIMH), part of the National Institutes of Health (NIH), shows.

Tiny DNA molecules show liquid crystal phases, pointing to new scenario for first life on earth

A team led by the University of Colorado at Boulder and the University of Milan has discovered some unexpected forms of liquid crystals of ultrashort DNA molecules immersed in water, providing a new scenario for a key step in the emergence of life on Earth.

New portable and low-cost device will make quality control of radiotherapy treatments possible

The research team from the Department of Electronics and Computer Science at the University of Granada (UGR), together with the Department of Radiology at the Hospital Virgen de las Nieves in Granada, have designed a portable and low-cost device which can measure the ionizing radiation someone is exposed to, for example, during radiotherapy.

Use of intraoperative MRI adds time but care-changing information to neurosurgery, study shows

Although the use of intraoperative MRI can add time to surgical procedures, it can help surgeons detect residual disease and, if needed, modify their plan for surgery while the patient is on the operating room table, according to a study conducted by researchers at the University Hospitals of Cleveland/Case Western Reserve University in Cleveland, OH and Johns Hopkins University in Baltimore, MD.

Bacteria shed light on an important group of human proteins

A collaboration between researchers in Switzerland, the UK and France has led to the solution of the first crystal structure of a member of the Rhesus protein family and thereby shed new light on a group of proteins of great importance in human transfusion medicine.

Cethromycin achieves all endpoints in second pivotal Phase III Trial for treatment for pneumonia

Advanced Life Sciences Holdings, Inc. (Nasdaq: ADLS), today announced positive results from Trial CL-05, the second of two pivotal phase III clinical trials designed to assess the safety and effectiveness of cethromycin, a novel once-a-day oral antibiotic for the treatment of mild-to-moderate community acquired pneumonia (CAP), the sixth leading cause of death in the United States.

Head-to-head comparison of Forteo and Fosamax

The osteoporosis drug Forteo works better than Fosamax to strengthen bones in arthritis patients with prednisone-induced osteoporosis, according to a new study from a researcher at the University of Alabama at Birmingham (UAB.)

Telomerase enzyme structure provides significant new target for anti-cancer therapies

Inappropriate activation of a single enzyme, telomerase, is associated with the uncontrollable proliferation of cells seen in as many as 90 percent of all of human cancers. Since the mid-1990s, when telomerase was first identified in human tumors, scientists have eyed the enzyme as an ideal target for developing broadly effective anti-cancer drugs.

Lung cancer treatment leads to Irish honour

A new scanning technique to improve radiotherapy treatment of lung cancer has been developed by a team led by Dr Gerry Hanna, and Dr Alan Hounsell, from Queen’s University.

Molecular docking unlocks function of enzymes

Fitting a key into a lock may seem like a simple task, but researchers at Texas A&M University are using a method that involves testing thousands of keys to unlock the functions of enzymes, and their findings could open the door for new targets for drug designs.

Skipping meals to lose weight

Foregoing food for a day each month stood out among other religious practices in members of the Church of Jesus Christ of Latter-Day Saints (LDS or Mormons), who have lower rates of heart disease than other Americans, researchers reported at the American Heart Association's Scientific Sessions 2007.

New technique determines age of living subjects using chest and dental x-rays

Researchers from the Laboratory of Anthropology at the University of Granada have devised a new technique to determine the age of living subjects using chest and dental x-rays.

64-slice CT scans a good test for clogged arteries

A study by an international team of cardiac imaging specialists, led by researchers at Johns Hopkins, concludes that sophisticated computed tomography (CT) scans of the heart and its surrounding arteries are almost as reliable and accurate as more invasive procedures to check for blockages.

CAD plus MDCT helps find solid lung nodules early

Computer-aided detection combined with MDCT improves radiologists' ability to detect solid lung nodules early enough for them to be treated without increasing interpretation time according to a recent study conducted by researchers at Hopital Pitie-Salpetriere in Paris, France.

Minority patients do not necessarily have worse outcomes after liver transplantation

When treated at the same medical centers as Caucasians, they fare just as well. These are the results of a new study in the November issue of Hepatology, a journal published by John Wiley & Sons on behalf of the American Association for the Study of Liver Diseases (AASLD). The article is also available online at Wiley Interscience.
