Aging and Alzheimer's disease: Novel brain imaging technologies help create new insights

The emergence of multiple new brain imaging technologies and the combined application of these new approaches is helping to create new insights into aging and Alzheimer's disease. One of the hallmarks of Alzheimer's disease is the deposition of amyloid beta protein in clumps or "plaques" within the brain. These plaques can be measured in humans with PET scans that use a chemical marker or radiotracer called 11C-PIB.

'Molecular band-aid' may help protect hearts of Duchenne muscular dystrophy patients

Researchers at the University of Minnesota Medical School have discovered a chemical that may, over the long term, protect the hearts of Duchenne muscular dystrophy patients - a fatal and most common form of muscular dystrophy in children.

Workings of IGFs on muscle cells

The muscle-building abilities of hormones known as insulin-like growth factors (IGFs) are legendary. Just do an online search and you'll find not only scientific papers discussing the effects of IGFs on the cells that give rise to muscle tissue, but also scores of ads touting the purported benefits of IGF supplements for bodybuilding.

Illumina announces enhancement to OmniExpress BeadChip

Illumina, Inc. today unveiled its new HumanOmniExpress+ Custom BeadChip (OmniExpress+), an enhancement to the recently announced OmniExpress BeadChip that allows for the addition of up to 200,000 custom variants for a total of >900k variants per sample. OmniExpress+ leverages the proven iSelect custom genotyping infrastructure to provide researchers with unlimited flexibility in adding custom content for disease or pathway-specific markers, rare variants from the 1,000 Genomes Project, or panels for fine-mapping onto the industry’s most optimal set of SNPs.

New method may shed light on the mechanism behind folding and misfolding of proteins

Researchers at the Department of Chemistry at the Technische Universit-t M-nchen (TUM) have developed a method that allows the observation of local movements in proteins on a time scale of nanoseconds to microseconds.

Dual role of Notch signalling pathway

Scientists headed by ICREA researcher Marco Mil-n, at the Institute for Research in Biomedicine (IRB Barcelona), reveal a surprising new function of Notch protein that contrasts with the one known to date. Found in the cell membrane, this protein activates a signalling pathway that regulates the expression of genes that make the cell divide, grow, migrate, specialise or die.

Study suggests HuR gene plays a critical role in inducing cells' inflammatory response

To understand the role of inflammation in cardiovascular and other diseases, it is essential to identify and characterize genes that induce an inflammatory response in the body -- and the genes that regulate them.

Human brain processes predictable sensory input more efficiently

The human brain processes predictable sensory input more efficiently. Alink and colleagues based this conclusion on the characteristics of responses in the primary visual cortex. It is known that the primary visual cortex is critical for vision and that responses in this brain area create a map of what we are currently looking at.

Link between potential hyper-activity of mTOR signalling pathway and cancer cells

The link between obesity and disease has been well documented. There's evidence now that obesity and cancer have a strong link, as they've shown in the United States at least 90,000 cancer deaths a year can be attributed to obesity. University of Alberta researcher Richard Lamb is on his way to understanding the correlation and it's a good example of how the scientific process works.

Concurrent use of proton-pump inhibitor and clopidogrel does not elevate cardiovascular risk

Heart patients who took a stomach acid-suppressing proton-pump inhibitor along with clopidogrel - a drug that prevents blood clots - were only half as likely to be hospitalized for upper digestive tract bleeding than those who used clopidogrel alone, according to a new study supported by HHS' Agency for Healthcare Research and Quality and the National Heart, Lung, and Blood Institute at the National Institutes of Health.

CLC bio releases groundbreaking whole-genome de novo assembler

Today, CLC bio released a groundbreaking whole-genome de novo assembler that will assemble genomes of any size, including human and plant genomes on a single workstation computer. Equally important, CLC bio’s de novo assembler is the first assembler that enables molecular biologists to set up, adjust, and run their large genome de novo assemblies through a graphical user-interface.
