Breast cancer cells have to learn to walk before they can run

Early-stage breast cancer that has not yet invaded the surrounding tissues may already contain highly motile cells, bringing the tumor one step closer to metastasis, report researchers at the Salk Institute for Biological Studies.

Allergic reactions to gadolinium-containing contrast injections - study

Allergic-like reactions to gadolinium-containing contrast injections in adults and pediatric patients (those younger than 19 years of age) are rare, according to a recent study conducted by researchers at the University of Michigan Health Systems in Ann Arbor.

Cone-beam breast CT compared to conventional mammography

Cone-beam breast CT provides exceptional tissue contrast and can potentially reduce examination time with comparable radiation dose to conventional 2D mammography, according to a new study by a team of researchers from the University of Texas M. D. Anderson Cancer Center in Houston.

The blood-brain barrier: A misunderstood key to finding life-saving cures to brain disease

An international team of scientists that includes a Saint Louis University researcher suggest several strategies to propel research for treatments of brain diseases that include multiple sclerosis, Alzheimer's disease, obesity and stroke in the January issue of the Lancet Neurology.

Study examines computed tomographic pulmonary angiography for diagnosing blood clots in the lung

New research indicates that a diagnostic strategy using computed tomographic pulmonary angiography (CTPA) may be a safe alternative to conventional lungs scans (known as ventilation-perfusion scans) for excluding the diagnosis of pulmonary embolism (blood clots in the lung vessels), although CTPA may detect more clots, according to a study in the current issue of JAMA: The Journal of the American Medical Association.

Safer, more accurate, and more effective radiation therapy for pregnant women

Developing fetuses are extremely sensitive to radiation, which poses an impossible dilemma for expecting mothers in need of screening or treatment for cancer.

A new brain imaging study identifies 'brain signature' for cigarette cravings

A new brain imaging study by researchers in the Abramson Cancer Center of the University of Pennsylvania shows that cigarette cravings in smokers who are deprived of nicotine are linked with increased activation in specific regions of the brain.

Brains respond differently to thirst depending upon age

Twelve healthy subjects in their 60s and 70s showed a different pattern of brain activations during thirst and satiation than did 10 healthy subjects in their 20s who drank the same amounts and underwent imaging with positron-emission tomography (PET).

Brain malfunction explains dehydration in elderly

As Australia faces another hot, dry summer, scientists from Melbourne's Howard Florey Institute have warned that elderly people are at risk of becoming dehydrated because their brains underestimate how much water they need to drink to rehydrate.

How molecular muscles help cells divide

Time-lapse videos and computer simulations provide the first concrete molecular explanation of how a cell flexes tiny muscle-like structures to pinch itself into two daughter cells at the end of each cell division, according to a report in Science Express.

Researchers report protein interactions of MAP kinase signaling pathway

The Stowers Institute's Rong Li Lab, in collaboration with the Institute's Imaging Center, has achieved a quantitative in vivo measurement of the dynamic protein-protein interactions in the mitogen-activated protein (MAP) kinase cascade signaling pathway, which is critical to growth and differentiation decisions in all eukaryotic cells.
