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.

New malaria agent found in chimpanzees close to that commonly observed in humans
Posted on 31. May, 2009 by admin.
Researchers based in Gabon and France report the discovery of a new malaria agent infecting chimpanzees in Central Africa. This new species, named Plasmodium gaboni, is a close relative of the most virulent human agent P. falciparum; it is described in an article published May 29 in the open-access journal PLoS Pathogens.
P. falciparum is the [...]

How oxidative stress may help prolong life
Posted on 31. May, 2009 by admin.
Oxidative stress has been linked to aging, cancer and other diseases in humans. Paradoxically, researchers have suggested that small exposure to oxidative conditions may actually offer protection from acute doses. Now, scientists at the University of California, San Diego, have discovered the gene responsible for this effect. Their study, published in PLoS Genetics on May [...]
