Vitamin C linked to reduced risk of stroke
Date: Feb-17-2014A study due to be presented at a conference later this year suggests that eating foods containing vitamin C, such as oranges, peppers, strawberries, papaya and broccoli, may be linked to a reduced risk for hemorrhagic stroke.According to the US Centers for Disease Control and Prevention (CDC), stroke is the fourth leading cause of death in the US, where every year 795,000 Americans suffer a stroke and 130,000 die from one.There are two main types of stroke: ischemic and hemorrhagic.
Indigenous response to natural disaster could be replicated elsewhere
Date: Feb-17-2014When a tsunami struck American Samoa in 2009, indigenous institutions on the islands provided effective disaster relief that could help federal emergency managers in similar communities nationwide, according to a study from the University of Colorado Denver and the University of Hawaii at Manoa.The study found that following the tsunami, residents of the remote U.S. territory in the South Pacific relied on Fa'aSamoa or The Samoan Way, an umbrella term incorporating a variety of traditional institutions governing the lives of its citizens.
A step closer to efficient treatment for cancer-causing herpes
Date: Feb-17-2014Herpes virus proteins are more 'spaghetti-like' than previously thought, which provides a vital clue in the search for an efficient treatment against a type of herpes which causes a form of cancer known as Kaposi's sarcoma.That's according to researchers from The University of Manchester who have discovered that the virus protein uses its flexible arms to pass on viral building blocks to the proteins of cells that it hijacks.

Stock market volatility and mental disorders linked
Date: Feb-17-2014Falling stock prices lead to increased hospitalisations for mental disorders, according to new research published in the journal Health Policy and Planning.Researchers assessed the relationship between stock price movements and mental disorders using data on daily hospitalisations for mental disorders in Taiwan over 4,000 days between 1998 and 2009. They found that a 1000-point fall in the Taiwan Stock Exchange Capitalisation Weighted Stock Index (TAIEX) coincided with a 4.71% daily increase in hospitalisations for mental disorders.
'Smart' gold nanoshells transport cancer drugs
Date: Feb-17-2014Nanoparticles capable of delivering drugs to specifically targeted cancer cells have been created by a group of researchers from China.The multifunctional 'smart' gold nanoshells could lead to more effective cancer treatments by overcoming a major limitation of modern chemotherapy techniques - the ability to target cancer cells specifically and leave healthy cells untouched.Small peptides situated on the surface of the nanoshells are the key to the improved targeting ability, guiding the nanoshells to specific cancer cells and attaching to markers on the surface of the cells.
How beneficial bacteria communicate with human cells
Date: Feb-17-2014Communication is vital to any successful relationship. Researchers from the Institute of Food Research and the University of East Anglia have discovered how the beneficial bacteria in our guts communicate with our own cells.This is a key step in understanding how our bodies maintain a close relationship with the population of gut bacteria that plays crucial roles in maintaining our health, fighting infection and digesting our food.A study, published in the journal Cell Reports, shows that the gut bacteria produce an enzyme that modifies signalling in cells lining the gut.
Switch discovered that decides cell fate
Date: Feb-17-2014Harvard stem cell scientists have a new theory for how stem cells decide whether to become liver or pancreatic cells during development. A cell's fate, the researchers found, is determined by the nearby presence of prostaglandin E2, a messenger molecule best known for its role in inflammation and pain. The discovery, published in the journal Developmental Cell, could potentially make liver and pancreas cells easier to generate both in the lab and for future cell therapies.

Stem cells help to rebuild the brain after stroke
Date: Feb-17-2014Enhancing the brain's inherent ability to rebuild itself after a stroke with molecular components of stem cells holds enormous promise for treating the leading cause of long-term disability in adults.Michael Chopp, Ph.D., Scientific Director of the Henry Ford Neuroscience Institute, presented this approach to treating neurological diseases at the American Heart Association's International Stroke Conference in San Diego.
