Unsuspected protein CD147, regulates the production of plaque-forming peptides that are the defining feature of Alzheimer's

Researchers at the Department of Energy's Lawrence Berkeley National Laboratory have discovered an unsuspected subunit of the protein complex gamma-secretase, which plays a central role in Alzheimer's disease.

Breast CT may improve on mammography - more gentler, more accurate

A new breast screening technology that may be able to detect tumors earlier than mammography -- without the need for uncomfortable breast compression -- is being tested in patients at the University of California, Davis, Medical Center.

New laser technology for more precise cancer treatments

Tom Cowan’s team is thinking smaller, but with big impact. Particle accelerators are a key research tool in a high energy physicist’s arsenal, but they take up a lot of space - miles and miles of it. But at the University of Nevada, Reno, smaller is better.

Scientists take aim at virulent bacteria by decoding machinery of key control enzyme

By deciphering the ingenious mechanism used by a particular enzyme to modify bacterial chromosome chemistry, scientists have come a step closer to designing a new kind of drug that could stop virulent bacterial infections in their tracks. Their research will be published in the May 6 issue of the journal Cell.

Researchers make new advances in determining the structure of all possible DNA sequences

Oregon State University researchers have made significant new advances in determining the structure of all possible DNA sequences – a discovery that in one sense takes up where Watson and Crick left off, after outlining in 1953 the double-helical structure of this biological blueprint for life.

Fusing physics with medicine to fight cancer

Everyone’s lives are touched by cancer - it is a disease that affects 1 in 3 of us throughout our lifetime. Future developments that lead to earlier diagnosis and more effective therapy lie in further successful collaboration between high energy physicists and the healthcare industry.

Common chest X-ray in the elderly can reveal osteoporosis

According to Canadian researchers undetected osteoporosis in the elderly might be discovered if chest X-rays that are done for other reasons were examined for fractures of the vertebrae.

Color doppler sonography speeds detection of necrotizing enterocolitis in premature infants

Measuring blood flow to a newborn's intestines using a special form of ultrasound can help radiologists identify a life-threatening complication in a serious bowel disease, according to a study in the May issue of the journal Radiology.

Chest x-rays may provide information to help detect osteoporosis in the elderly

Undetected osteoporosis in the elderly might be discovered if chest radiographs (x-ray images) that are done for other reasons were examined for fractures of the vertebrae, according to an article in the April 25 issue of Archives of Internal Medicine.

Breast cancer detector that uses electricity instead of X-rays

A painless, portable device that uses electrical current rather than X-ray to examine breasts for cancer is under study at the Medical College of Georgia.

Using X-ray crystallography, researchers have "seen" the structural basis for antibiotic resistanc

Using X-ray crystallography, researchers at Yale have "seen" the structural basis for antibiotic resistance to common pathogenic bacteria, facilitating design of a new class of antibiotic drugs, according to an article in Cell.

Researchers make gains in understanding antibiotic resistance

Howard Hughes Medical Institute researchers chiseling away at the problem of antibiotic resistance now have a detailed explanation of how the drugs' main cellular target in bacteria evolves to become resistant to some of these medications.

Researchers study radiation blockers while conducting nuclear imaging of Iodine uptake in mouse tissues

Scientists have found that a dose five times higher than the FDA-recommended dosage of potassium iodide in the event of a nuclear accident is needed to protect small animals effectively from radioactive iodide in medical imaging procedures. The long-term animal nuclear imaging project is being conducted by a collaboration of biology and physics researchers from the Department of Energy's Jefferson Lab and The College of William & Mary (CWM).

Researchers determine structure of binding site of colon-cancer drug Erbitux and its protein target

Researchers at the University of Pennsylvania School of Medicine have determined the precise molecular details of how Erbitux, a recently approved colorectal cancer drug, binds to its target on cancer cells. Knowing this chemical configuration will lead to better drug design for this family of cancer medications.

You need to do vigorous activity if you want to be lean

Adolescents who get daily vigorous physical activity tend to be leaner and fitter than their less active peers, researchers have shown.

Study shows connection of varicose veins to chronic pelvic pain

Research presented today at the Society of Interventional Radiology's 30th Annual Scientific Meeting found that 16 percent of women with varicose veins in their legs simultaneously had ovarian varicose veins -- a common but often under-diagnosed cause of chronic pelvic pain.

New drug approved for treating endometriosis

Drug manufacturer Pfizer announced today that the U.S. Food and Drug Administration (FDA) has given approval for the release of depo-subQ provera 104 to be prescribed for the management of pain associated with endometriosis, a gynecological condition that affects one in ten women of reproductive age.
