CT Scan Technique Could Improve COPD Diagnosis And Treatment
Date: Oct-09-2012A new approach to lung scanning could improve the diagnosis and treatment of a lung disease that affects approximately 24 million Americans and is the country's third-highest cause of death. In a new paper published online in Nature Medicine, a team from the University of Michigan Medical School reports on a technique called parametric response mapping, or PRM...
Tomatoes Lower Stroke Risk
Date: Oct-09-2012If you eat plenty of tomatoes your risk of having a stroke will probably be lower, scientists from the University of Eastern Finland in Kuopio revealed in the October 9th issue of Neurology. The authors added that lycopene, an antioxidant in tomatoes, appears to have the stroke-prevention benefits. Several studies have been carried out on tomatoes and many have found that they do have significant health benefits...
New Research Takes Us Another Step Towards Understanding And Treating Melanoma
Date: Oct-09-2012These proteins are required for melanocyte stem cell self-maintenance and, as such, correct pigmentation throughout the mice's life span. Without these two proteins, the mice's fur turns white. Their research is published in the review Cell Report and paves the way for serious possibilities in terms of stopping the formation of melanomas, tumours that originate from melanocyte cells. Melanocytes are cells in the organism used for skin, fur and hair pigment. This pigmentation function provides protection from the sun and lends organisms their colour...
Treating HER2+ Breast Cancer With HIV Drug
Date: Oct-09-2012The HIV protease inhibitor, Nelfinavir, can be used to treat HER2-positive breast cancer in the same capacity and dosage regimen that it is used to treat HIV, according to a study published in the Journal of the National Cancer Institute. Breast cancer is one of the most common causes of cancer deaths in the U.S. with approximately 39,520 women succumbing to the disease in 2011. HER2-postive breast cancer is known to be more aggressive and less responsive to treatments compared to other types of breast cancer...
Electricity Found In Biological Clock
Date: Oct-09-2012Biologists from New York University have uncovered new ways our biological clock's neurons use electrical activity to help keep behavioral rhythms in order. The findings, which appear in the journal Current Biology, also point to fresh directions for exploring sleep disorders and related afflictions. "This process helps explain how our biological clocks keep such amazingly good time," said Justin Blau, an associate professor of biology at NYU and one of the study's authors...
Medical Advances May Be An Unexpected Offshoot Of Tree Nut Research
Date: Oct-09-2012Prescription drugs that today help patients fight severe fungal infections might tomorrow be even more effective, thanks to unexpected findings from agriculture-based, food-safety-focused studies by U.S. Department of Agriculture (USDA) scientists and their colleagues. Petri-dish experiments conducted by now-retired Agricultural Research Service (ARS) research leader Bruce C. Campbell, ARS molecular biologist Jong H...
A New Information-Theoretical Model Of Human Sensory Perception And Memory Sheds Light On Some Peculiarities Of The Nervous System.
Date: Oct-09-2012Ask adults from the industrialized world what number is halfway between 1 and 9, and most will say 5. But pose the same question to small children, or people living in some traditional societies, and they're likely to answer 3. Cognitive scientists theorize that that's because it's actually more natural for humans to think logarithmically than linearly: 30 is 1, and 32 is 9, so logarithmically, the number halfway between them is 31, or 3. Neural circuits seem to bear out that theory...
Drinking Milk Said To Protect From Colon Cancer Progression
Date: Oct-09-2012A protein that exists in milk can significantly reduce the rate at which colon cancer cells grow over time, researchers from the University of Lund, Sweden, reported in the Journal of Dairy Science, the official journal of the American Dairy Science Association. Previous studies have shown that milk can reduce the risk of developing diabetes and metabolic syndrome. One study found that milk can also positively impact your brain and mental performance...
Learning About Nausea Through 'Disgusted' Rats: Research May Lead To New Cancer Treatments
Date: Oct-09-2012Nausea is a common and distressing side effect of many drugs and treatments. Unlike vomiting, nausea is not well understood, but new research by University of Guelph scientists may soon change that. Guelph PhD student Katharine Tuerke, neuroscience researcher Cheryl Limebeer and Prof. Linda Parker in the Department of Psychology believe they've found the mechanism in the brain that is responsible for the sensation of nausea - with the help of some "disgusted" rats. Their study was published this week in Journal of Neuroscience...
Mechanism Identified That Protects Our Brains From Turning Stress And Trauma Into Post-Traumatic Stress Disorder
Date: Oct-09-2012Researchers from the University of Exeter Medical School have for the first time identified the mechanism that protects us from developing uncontrollable fear. Our brains have the extraordinary capacity to adapt to changing environments - experts call this 'plasticity'. Plasticity protects us from developing mental disorders as the result of stress and trauma. Researchers found that stressful events re-programme certain receptors in the emotional centre of the brain (the amygdala), which the receptors then determine how the brain reacts to the next traumatic event...
