Drug to reverse breast cancer spread in development

Posted: 25 Jan 2014 07:49 PM PST

Researchers at Cardiff University are developing a novel compound known to reverse the spread of malignant breast cancer cells. The vast majority of deaths from cancer result from its progressive spread to vital organs, known as metastasis. In breast cancer up to 12,000 patients a year develop this form of the disease, often several years after initial diagnosis of a breast lump. In a recent series of studies, researchers identified a previously unknown critical role for a potential cancer causing gene, Bcl3, in metastatic breast cancer.

Highly reliable brain-imaging protocol identifies delays in premature infants

Posted: 25 Jan 2014 02:24 PM PST

Infants born prematurely are at elevated risk for cognitive, motor, and behavioral deficits -- the severity of which was, until recently, almost impossible to accurately predict in the neonatal period with conventional brain-imaging technology. But physicians may now be able to identify the premature infants most at risk for deficits as well as the type of deficit, enabling them to quickly initiate early neuroprotective therapies, by using highly reliable 3-D MRI imaging techniques developed by clinician scientists.

High-intensity strength training shows benefit for Parkinson's patients

Researchers say that high-intensity strength training produced significant improvements in quality of life, mood and motor function in older patients with Parkinson's disease.

Infections damage ability to form spatial memories

Posted: 24 Jan 2014 08:11 AM PST

Increased inflammation following an infection impairs the brain's ability to form spatial memories, according to new research. The impairment results from a decrease in glucose metabolism in the brain's memory center, disrupting the neural circuits involved in learning and memory. This is the first study to image the effects of inflammation on the brain. The findings help explain why inflammation impairs memory and could spur the development of new drugs targeting the immune system to treat dementia.

More relief options may be available for hay fever sufferers

Posted: 24 Jan 2014 08:07 AM PST

There is more to seasonal allergies than a little congestion and sneezing. If you notice eating watermelon, cantaloupe or avocado make you cough and itch, it may be a symptom of ragweed allergy. But more help might be on the way for some of the 23 million hay fever sufferers.

Researchers identify two HIV-1 envelope immunogens capable of eliciting antibodies associated with vaccine protection

Researchers identified two HIV-1 Envelope immunogens that elicit broadly neutralizing antibodies when introduced as a vaccine.

Researchers find epileptic activity spreads in new way

Posted: 24 Jan 2014 06:37 AM PST

Biomedical engineers have found that epileptic activity can spread through a part of the brain in a new way, suggesting a possible novel target for seizure-blocking medicines. Evidence from a series of experiments and computer modeling strongly suggests individual cells in a part of the brain, known as the hippocampus, use a small electrical field to stimulate and synchronize neighboring cells, spreading the activity layer by layer.

Diabetes: Having a spouse with diabetes is a risk factor for diabetes yourself

Posted: 24 Jan 2014 05:27 AM PST

Living in a household implies sharing duties and responsibilities but it could also imply sharing your diabetes. Medical researchers have shown, through combined analyses of several studies, evidence that spousal diabetes is a diabetes risk factor.
