How good cholesterol turns bad (2/29/2012)

How good cholesterol turns badBerkeley Lab researchers have found new evidence to explain how cholesteryl ester transfer protein (CETP) mediates the transfer of cholesterol from "good" high density lipoproteins (HDLs) to "bad" low density lipoproteins (LDLs). These findings point the way to the design of safer, more effective next generation CETP inhibitors that could help prevent the development of heart disease. ...> Full Article


The molecular basis of touch sensation (2/28/2012)

A gene known to control lens development in mice and humans is also crucial for the development of neurons responsible for mechanosensory function, as neurobiologists of the Max Delbrueck Center Berlin-Buch have now discovered. They found that in mice in which they had removed the c-Maf gene in the nerve cells, touch sensation is impaired. This similarly applies to human carriers of a mutant c-Maf gene. ...> Full Article

Food scientists fortify goat cheese with fish oil to deliver healthy omega-3 fatty acids (2/26/2012)

Fish oil is an underused ingredient in the food industry because of its association with a strong odor and aftertaste. A new study in the February issue of the Journal of Food Science, published by the Institute of Food Technologists, shows that fish oil can be added to goat cheese to deliver high levels of heart-healthy omega-3 fatty acids without compromising taste or shelf-life. ...> Full Article

Study to determine whether fish oil can help prevent psychiatric disorders (2/20/2012)

This new study is a National Institute of Mental Health-funded randomized double-blind trial that was designed to test whether Omega-3 fatty acids improve clinical symptoms, and help adolescents and young adults (ages 12 to 25) who are at elevated risk for severe psychiatric disorders function better in school, work and other social environments. ...> Full Article


Top off breakfast with -- chocolate cake? (2/19/2012)

In a study of nearly 200 clinically obese, non-diabetic adults, professor Daniela Jakubowicz of Tel Aviv University found that a 600-calorie breakfast that includes dessert as well as proteins and carbohydrates can help dieters lose weight and keep it off over the long term. Her research indicates that such a morning meal staves off cravings and defuses psychological addictions to sweet foods. ...> Full Article


Why the middle finger has such a slow connection (2/18/2012)

Each part of the body has its own nerve cell area in the brain -- we therefore have a map of our bodies in our heads. The functional significance of these maps is largely unclear. What effects they can have is now shown by RUB neuroscientists through reaction time measurements combined with learning experiments and "computational modeling." They have been able to demonstrate that inhibitory influences of neighboring "finger nerve cells" affect the reaction time of a finger. ...> Full Article


The heart can make 'bad' fat burn calories (2/17/2012)

Brown fat burns calories to generate body heat in rodents and newborn humans. Researchers seeking to combat the obesity epidemic are trying to develop ways to increase the amount of brown fat an adult human has in the hope that this will make them lose weight. New research indicates that hormones produced by the heart can cause regular fat cells from mice and humans to take on characteristics of brown fat cells. ...> Full Article

Heart failure is associated with loss of brain cells and a decline in mental processes (2/15/2012)

Australian researchers have found evidence that heart failure is associated with a decline in people's mental processes and a loss of grey matter in the brain. These changes can make it more difficult for heart failure patients to remember and carry out instructions such as taking the correct medication at the right times. The study is published in the European Heart Journal. ...> Full Article


Potatoes lower blood pressure in people with obesity and hypertension without increasing weight (2/14/2012)

The first study to check the effects of eating potatoes on blood pressure in humans has concluded that two small helpings of purple potatoes a day decreases blood pressure by about four percent without causing weight gain. In a report in the ACS' Journal of Agricultural and Food Chemistry, the researchers say that decrease, although seemingly small, is sufficient to potentially reduce the risk of several forms of heart disease. ...> Full Article


Does online dating really work? (2/14/2012)

Whether enlisting the help of a grandmother or a friend or the magic of Cupid, singles long have understood that assistance may be required to meet someone special. Today such help is likely to come from online methods of matchmaking. But online dating, according to new Northwestern University research, depends largely on ineffective algorithms and profiles for finding potential love interests. Mobile dating, the latest iteration in digital dating, however, may hold the most promise. ...> Full Article


Twinkle, twinkle kidney stone: With a push you could be gone (2/13/2012)

What would happen if an astronaut developed kidney stones during a mission? Space researchers are developing ultrasound technology that uses enhanced imaging capabilities to detect stones and then give a "push" to help the stones pass naturally. This technology could also change the way kidney stones are treated on Earth. The researchers hope to begin clinical trials this summer. ...> Full Article

Brown fat burns calories in adult humans (2/6/2012)

Brown fat burns calories to generate body heat in rodents and newborn humans. Recently, adult humans have also been found to possess brown fat, leading to the suggestion that increasing the amount of brown fat a person has will make them slimmer. However, it has never been shown definitively that adult human brown fat burns energy. But now, researchers in Canada have provided this evidence. ...> Full Article

New tool enhances view of muscles (2/3/2012)

Simon Fraser University researcher James Wakeling is adding to the arsenal of increasingly sophisticated medical imaging tools with a new signal-processing method for viewing muscle activation details never seen before. His novel method using ultrasound imaging, 3D motion-capture technology and proprietary data-processing software can scan and capture 3D maps of the muscle structure in just 90 seconds. Previous methods took 15 minutes -- far too long to ask people to hold a muscle contraction. ...> Full Article

In a recent University of Illinois study, scientists showed that human colon cancer cells die when they are exposed to the approximate number of bioactive compounds present in one cup of mate tea, which has long been consumed in South America for its medicinal properties. "The caffeine derivatives in mate tea not only induced death in human colon cancer cells, they also reduced important markers of inflammation," said Elvira de Mejia, a U of I associate professor of food chemistry and food toxicology. ...> Full Article
