San Diego, CA — Alzheimer's disease (AD) is an incurable, progressive neurodegenerative disease affecting over five million people worldwide, and is the leading cause of dementia in the elderly. Currently, intravenous human immunoglobulin (IVIG) treatment is being explored in multiple off-label uses other than immunotherapy, including AD. Several clinical studies assessing the tolerability and efficacy of IVIG in Alzheimer's disease subjects are in progress with inconsistent outcomes. Recent studies conducted by Dr.

Researchers from Norway and the United Kingdom have developed a new instrument to measure work addiction: The Bergen Work Addiction Scale. The new instrument is based on core elements of addiction that are recognised as diagnostic criteria for several addictions.

Some people seem to be driven to work excessively and compulsively. These are denoted as work addicts – or workaholics.

New Rochelle, NY, April 23, 2012-- Videogame technology is proving to be a valuable tool for helping people of all ages improve lifestyle and health habits and manage disease. New research is showing that exergames have significant benefits for older adults by providing cognitive stimulation and a source of social interaction, exercise, and fun.

SAN DIEGO—Obstructive sleep apnea (OSA) is a disorder in which there are recurring episodes of upper airway collapse during sleep with ongoing effort to breathe. OSA is estimated to affect 1 in 5 adults in America. The serious nature of the problem was captured in a landmark study which found that middle-age and older men with even mild levels of OSA were in danger of increased risk of stroke and death. While a link between OSA and stroke is clear, OSA's effect on the cerebral (brain) vessels is not.

KATHMANDU, NEPAL (24 April 2012)—Today, recognizing the knowledge gap between the existing evidence of climate change and adaptation on the ground, researchers in Asia launched a novel learning platform to improve agricultural resilience to changing weather patterns, and to reduce emissions footprint.

Tampa, Fla. (April. 23, 2012) –When laboratory mice were modeled with colitis and treated with human umbilical cord-derived mesenchymal cells, the cells homed in on the inflamed colon and effectively ameliorated colitis, reported a study published in a recent issue of Cell Transplantation (20:9), now freely available on-line at http://www.ingentaconnect.com/content/cog/ct/.

Tampa, Fla. (April. 23, 2012) – Researchers interested in determining the direct effects of a high saturated fat and high cholesterol (HFHC) diet on implanted fetal hippocampal tissues have found that in middle-aged laboratory rats the HFHC diet elevated microglial activation and reduced neuronal development.

WASHINGTON, D.C., April 18, 2012 – Serious birth defects of the brain and spine in America's babies, particularly those of Hispanic origin, could be reduced if the nation's corn masa flour products were fortified with the B vitamin folic acid, according to a new petition filed with the U.S. Food and Drug Administration (FDA) by a coalition of six organizations:

St. Jude Children's Research Hospital scientists have rewritten the job description of the protein TopBP1 after demonstrating that it guards early brain cells from DNA damage. Such damage might foreshadow later problems, including cancer.

Olympic boxers can exhibit changes in brain fluids after bouts, which indicates nerve cell damage. This is shown in a study of 30 top-level Swedish boxers that was conducted at the Sahlgrenska Academy at the University of Gothenburg, Sweden, in collaboration with the Swedish Boxing Federation, published in PLoS ONE.

Researchers at Lund University have discovered a new stem cell in the adult brain. These cells can proliferate and form several different cell types - most importantly, they can form new brain cells.Now the researchers hope to put the discovery to use to develop methods that can repair diseases and injury to the brain.

CHAPEL HILL, N.C. – Scientists at the University of North Carolina at Chapel Hill have identified a new way to deliver long-lasting pain relief through an ancient medical practice.

In an article published in the April 23 online edition of Molecular Pain, UNC researchers describe how exploiting the molecular mechanism behind acupuncture resulted in six-day pain relief in animal models. They call this new therapeutic approach PAPupuncture.

A small minority of today's university students don't use email and others are confused by the array of technologies available at universities. Yet many students couldn't bear to be without their mobile phones and find themselves distracted by social networking sites during study.

SAN DIEGO— 'Brain freeze' is a nearly universal experience—almost everyone has felt the near-instantaneous headache brought on by a bite of ice cream or slurp of ice-cold soda on the upper palate. However, scientists are still at a loss to explain this phenomenon. Since migraine sufferers are more likely to experience brain freeze than people who don't have this often-debilitating condition, brain freeze may share a common mechanism with other types of headaches, including those brought on by the trauma of blast-related combat injuries in soldiers.
