First synthetic activator of two critical proteins identified: New approach to treat numerous metabolic disorders? (November 19, 2010) -- Scientists have identified a novel synthetic activator of a pair of proteins that belong to a protein family playing key roles in human metabolism and immune function. The discovery could provide new and potentially more effective therapeutic approaches to diseases ranging from diabetes to osteoporosis. ... > full story
Pomegranate juice reduces damage to tissues, inflammation and infections, study suggests (November 19, 2010) -- Studies in recent years have claimed multiple health benefits of pomegranate juice, including that it is a good source of antioxidants and lowers both cholesterol and blood pressure, especially in diabetic and hypertensive patients. A preliminary study now suggests that it can ward off a number of complications in kidney disease patients on dialysis, according to new study. ... > full story
First successful salivary stone removal with robotics (November 19, 2010) -- Doctors report the first use of a surgical robot guided by a miniature salivary endoscope to remove a 20mm salivary stone and repair the salivary duct of a patient. Giant stones have traditionally required complete removal of the salivary gland. This technique not only saves the salivary gland, but reduces blood loss, scarring, and hospital stay. ... > full story
Physicists study behavior of enzyme linked to Alzheimer's, cancer (November 19, 2010) -- Physicists are using complex computer simulations to illuminate the workings of a crucial protein that, when malfunctioning, may cause Alzheimer's and cancer. Their hope is to one day contribute to developing medication that not only can precisely recognize and target a key that causes Alzheimer's or cancer inside a crowded cell, but also then switch a sick cell like that back to its healthy form of interaction at a molecular level. ... > full story
Study finds evidence of gender bias toward diagnosing boys with autism (November 19, 2010) -- Social factors can play a key role in whether or not a child is diagnosed as autistic, a new study has found. Boys were more likely to receive a diagnosis of autistic spectrum disorder than girls, even when symptoms were equally severe, according to researchers. ... > full story
E. coli infection linked to long-term health problems (November 19, 2010) -- People who contract gastroenteritis from drinking water contaminated with E coli are at an increased risk of developing high blood pressure, kidney problems and heart disease in later life, finds a new study. ... > full story
Potential genetic target for heart disease discovered (November 19, 2010) -- Researchers have found a potential genetic target for heart disease, which could lead to therapies to prevent the development of the nation's number one killer in its initial stages. ... > full story
Taking a break from osteoporosis drugs can protect bones, study finds (November 19, 2010) -- Taking time off from certain osteoporosis drugs may be beneficial to bone health, according to a new study. Researchers found that bone density remained stable for three years in patients who took a drug holiday from bisphosphonates, a popular class of osteoporosis drugs that can cause fractures in the thigh bones and tissue decay in the jaw bone. ... > full story
Coaching with compassion can 'light up' human thoughts (November 19, 2010) -- Researchers have used an fMRI to document reactions in the human brain to compassionate and critical coaching methods. Students tended to activate areas of the brain associated with openness to learning when working with coaches who inspired them. Students tended to shut down when coaches were perceived as judgmental. ... > full story
Scientists discover how estrogen works and flip its switch to reap benefits without risks (November 19, 2010) -- Estrogen sharpens mental performance in humans and animals and shows promise as a treatment for brain disorders. But long-term estrogen therapy increases the risk of cancer, heart disease and stroke. Researchers have now discovered how to reap estrogen's benefits without the risk. Using a special compound, they flipped a switch that mimics the effect of estrogen on cortical brain cells. The scientists also found how estrogen physically works in brain cells to boost mental performance. ... > full story
Chemicals' study pinpoints threat to workers' lungs (November 19, 2010) -- Tiny particles used in a range of everyday products from computers to shampoo can adversely affect the lungs in very different ways, a study has shown. Research suggests that industrial manufacturers using nanoparticles should be aware of the risks that different types of nanoparticles pose to workers who handle them. ... > full story
Controlling cursors with thoughts: Faster, simpler, and more accurately; advance helps people regulate their own brain response, with therapeutic implications (November 19, 2010) -- Using a new brain-computer training approach, 14 volunteers learned in only six minutes how to move a screen cursor with their thoughts. Near-instant feedback helped the people quickly master some of their own brain responses. ... > full story
