Where the brain harbors unconscious fears

...rs said that their experimental technique not only pinpoints an important structure involved in the neural circuitry of processing fearful stimuli, but also offers a way to measure the success of therapies for anxiety disorders. The researchers concentrated on the amygdala because the almond-shaped structure i...

For first time, brain cells generated in a dish

...he body can on its own. In addition, the discovery pinpoints the cell that is truly what people refer to when they say "stem cell." Although the term is used frequently to describe immature cells that are the building blocks of bones, skin, flesh and organs, the actual stem cell as it exists in the brain has b...

Gladstone researchers identify new drug target for Alzheimer's disease

...eta was unable to harm the neurons. The study thus pinpoints NF-B as an important contributor to the destructive power of amyloid beta, making it a key drug target, and it singles out resveratrol as holding the most promise for therapeutic intervention....

Gladstone study links Alzheimer's with toxic protein fragments

... is a causative factor for Alzheimer's disease. It pinpoints mitochondria, the organelles within cells designed to turn glucose into energy, as a key site that specific fragments of a particular form of apoE attack, leading to the neuronal death characteristic of Alzheimer's disease (AD). The findings are publ...

New genetic discovery explains 74 percent cases of age-related macular degeneration

...researchers at Columbia University Medical Center, pinpoints the role that two genes Factor H and Factor B play in the development of nearly three out of four cases of age-related macular degeneration (AMD), a devastating eye disease that affects more than 10 million people in the United States. Findings ind...

Using the program, a health care department can determine the best location for emergency clinics based on population density and road accessibility, the most efficient facility layou...

Earliest fungi may have found multiple solutions to propagation on land, new study infers

A potential biological cause for sudden infant death syndrome

...ngs in a third population and, for the first time, pinpoints multiple defects in the serotonin system other than those in serotonin receptors: deficiencies in a particular type of serotonin receptor (called 5HT1A), an abnormally high number of serotonergic neurons (neurons that make and release serotonin), a p...

Researchers identify molecule that causes destructive lung inflammation in cystic fibrosis patients

...s and Children's pulmonologist Patricia Dubin, MD, pinpoints IL-23 as the crucial mediator to this inflammatory response. Results of this study are now published online in the American Journal of Physiology-Lung Cellular and Molecular Physiology. Many patients with CF develop chronic lung infections from a st...

Do you hear what I see?

WASHINGTON, DC February 16, 2007 -- New research pinpoints specific areas in sound processing centers in the brains of macaque monkeys that shows enhanced activity when the animals watch a video. This study confirms a number of recent findings but contradicts classical thinking, in which hearing, taste, to...

Scientists reveal structure of gateways to gene control

...ology and the study's lead investigator. The map pinpoints the locations of certain key gene-controlling nucleosomes -- spool-like structures that wrap short regions of DNA around a protein core. The research suggests how these nucleosomes, positioned at important transcription-promoter sites throughout the...

Study identifies a common genetic risk factor for colorectal and prostate cancer

...erm goal of developing a model that more precisely pinpoints who is at greater risk for developing colorectal, prostate, and other cancers. However, Henderson notes, We still need to identify the biological mechanism through which these variants are influencing the development of various cancers....
