Bacterial ‘fight club’ approach effective for finding new drugs from natural sources

Creating bacterial "fight clubs" is an effective way to find new drugs from natural sources. That is the conclusion of a team of Vanderbilt chemists who have been exploring ways to get bacteria to produce biologically active chemicals that they normally hold in reserve. These compounds are called secondary metabolites. [More]

Decreased removal of toxic peptides causes onset of Alzheimer's disease

Jens Pahnke and his team at the University of Oslo has recently published results in the prestigious scientific journal 'BRAIN' showing that decreased removal of toxic peptides in the brain causes the onset and first clinical signs of Alzheimer's disease, rather than overproduction as has previously been assumed. This information can now be used to target specific genes to enhance their function in the brain of elderly or people at risk. [More]

Blueberries may be effective in treatment for PTSD

Up to 8 percent of people in the U.S. suffer from post-traumatic stress disorder (PTSD) as the result of witnessing or being the victim of a traumatic event. People with PTSD have been in a situation in which they were at risk of death, serious injury or sexual violence or have seen first-hand loved ones faces such threats. They may experience flashbacks, emotional detachment and jumpiness, among other symptoms that affect their ability to function in everyday life. [More]
