Researchers demonstrate ability of experimental technique to image telltale brain plaques
UPTON, NY – Researchers at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have demonstrated a new, highly detailed x-ray imaging technique that could be developed into a method for early diagnosis of Alzheimer’s disease. The technique has previously been used to look at [...]

Implications for biotech applications; possible targets for infection-fighting drugs
UPTON, NY — An international team of scientists has discovered extensive similarities between a strain of bacteria commonly associated with plants and one increasingly linked to opportunistic infections in hospital patients. The findings suggest caution in the use of the plant-associated strain for a range of biotech [...]

Cells are like robust computational systems, Carnegie Mellon-led team reports
Posted on 18. Jun, 2009 by admin.
PITTSBURGH—Gene regulatory networks in cell nuclei are similar to cloud computing networks, such as Google or Yahoo!, researchers report today in the online journal Molecular Systems Biology. The similarity is that each system keeps working despite the failure of individual components, whether they are master genes or computer processors.
This finding by an international team led [...]

Depression may increase Alzheimer’s risk in people with memory problems
Posted on 18. Jun, 2009 by admin.
People with memory problems who are depressed are more likely to develop Alzheimer’s disease than those who aren’t depressed, according to a new UCLA study.
Researchers also found, however, that the popular Alzheimer’s drug donepezil may help delay the progression to Alzheimer’s in depressed individuals who suffer from mild cognitive impairment or memory problems.

Mayo genomic discovery: Protecting kidney function during heart failure
Posted on 18. Jun, 2009 by admin.
ROCHESTER, Minn. — Mayo Clinic cardiology researchers have found a peptide that helps preserve and improve kidney function during heart failure, without affecting blood pressure. Earlier variations of this peptide caused blood pressure to drop limiting the potential benefits to the kidneys. The findings appear in the current Proceedings of the National Academy of Sciences.
“Heart [...]

SLU researcher tests new treatment for virus
ST. LOUIS – In a multi-center trial led by a Saint Louis University researcher, investigators found that a new combination therapy of daily consensus interferon and ribavirin helps some hepatitis C patients who have not responded to previous treatment. The findings, published in the June issue of Hepatology, offer [...]

CHAPEL HILL, N.C. – In 2004, researchers at the University of North Carolina at Chapel Hill Lineberger Comprehensive Cancer Center announced a crucial discovery in the understanding of cellular aging. They found that as cells and tissues age, the expression of a key protein, called p16INK4a, dramatically increases in most mammalian organs. Because p16INK4a is [...]
