Yawning Actually Helps You Keep Awake

... think contagious yawning is triggered by empathic mechanisms which function to maintain group vigilance, the Daily Mail quoted lead researcher, Dr Gordon Gallup, as saying. For the study, the researchers recruited 44 college students to watch, individually, films of people yawning and recorded the number of ...

Insight Into Neural Stem Cells Has Implications For Designing Therapies

..., is a key step toward understanding the molecular mechanisms of neural stem cell potential. "Now you could compare adult stem cells in different regions at the genetic level. Since different neural stem cells make different types of neurons, maybe you could determine which genes are important for making, say, ...

Scientists Find Single Circuit Channeling Depression in Rats

...ingle brain circuit that appears to funnel all the mechanisms and treatments of depression. Depression-related behavior is manifested in changes in electrical signals moving through the circuit, according to the study released on the journal Science's website. Karl Deisseroth, a professor of bioengineering ...

New Asthma Gene Identified

...so-called 'asthma gene' would provide a new set of mechanisms to try and modify and manage childhood asthma, Abecasis said. "Before we finished the paper, we would have guessed (ORMDL3) would be a gene with a well-understood role in allergic responses, but that is not what we found," said Abecasis, noting tha...

Genetic Disease Causes hearing loss

Exercise Reduces Inflammation

...may help explain some of the underlying biological mechanisms that take place as the result of regular exercise. According to the researchers, that knowledge could potentially lead to a better understanding of the relationship between exercise and inflammation. The objective of their research was to examine t...

Brain Pathway for Depression Revealed

...spects and found so many treatments with different mechanisms that the condition remains an enigma. They found that in rats the differing mechanisms of depression and its treatment in the end appear to funnel through a single brain circuit. Changes ...

Liver Cancer More Prevalent in Males

...arty is seen in mice. In order to understand the mechanisms underlying gender disparity in HCC, the UCSD researchers used a chemical carcinogen, DEN, to induce cancer in mice. This resulted in HCC in 100 percent of male mice, but only in 10 to 20 percent of their female littermates. The researchers discover...

Top China Official Pessimistic on Fixing Food Safety Woes

'The inspection, prevention and emergency response systems of food safety departments... will face increasing pressure and challenges,'...

Selenium Supplements Could Increase Diabetes Risk

... of the disease. However, our understanding of the mechanisms whereby selenium would increase risk of diabetes is very limited at this time and this issue needs to be further explored. "Nevertheless, I would not advise patients to take selenium supplements greater than those in multiple vitamins," he said. ...

Global Warming: Lessons of History Help the Future

...nse to crisis. In Ireland and India, too, coping mechanisms were badly eroded by the time the emergency struck. The Industrial Revolution drove many of Ireland's farmers into poverty, as they lost non-farming income, such as making linen, to textile mills in Britain. In India, the rural fabric was ripped to...

Protein Instrumental to Brain Development and Repair Identified

...n and adults. "By understanding the fundamental mechanisms of brain development, we get closer to finding clear instructions to repairing developmental brain disorders and injuries," Dr. Vittorio Gallo, Director, Center for Neuroscience Research, Children's Research Institute at Children's National Medical C...

Boffins Identify Gene That can Protect Humans from Nephronopthisis

...research with clinical studies can help uncovering mechanisms of human disease," said Henriette Uhlenhaut who carried out the research in Treier's lab. "The next step will be to translate the insights gained into new therapeutic approaches to develop alternatives to kidney transplantations. With GLIS2 we have...

Visual Impairment Linked to Greater Mortality Risk

...and the risk of death in older individuals. "The mechanisms for higher mortality associated with visual impairment remain unclear. It could be attributed to age-related ocular conditions, such as age-related macular degeneration (ARMD) or cataract, which can be markers of biological aging. Alternatively, visu...

Uncooked Fish may Cause Liver Cancer

... (Khon Kaen University) and colleagues discuss the mechanisms by which the food-borne trematode Opisthorchis viverrini (the SE Asian liver fluke) causes cholangiocarcinoma. The fluke is endemic to Thailand, Lao Peoples Democratic Republic, Vietnam, and Cambodia. In Thailand alone, 6 million people are though...

Stem Cells Research in Parkinsons Disease
