     From VOA Learning English, this is the Health & Lifestyle report.
     In the future, to help treat people with brain diseases such as Alzheimer's and Parkinson's.
     These two diseases are age-relat tissue, especially the brain.
     People suffering from Alzheimer's and Parkinson's havedeposits of sticky plaque in their brains. Over time, this plaque reduces brain function. Eventually, death.
     Scientists say plaque can be reduced
     But scientists say the plaque deposits can be reduced with chemicals from plants, including prickly pear and brown seaweed. Scientists say the chemicals — or, extracts — appear to replace the harmful, sticky plaque with deposits that are less harmful.
     These scientists are researchers at the University of Malta and the National Center of Scientific Research at the University of Bordeaux.
     They tested the chemical extracts of the plants on a substance called Brewer's yeast. This yeast had plaque deposits similar to those seen in Alzheimer's disease. Scientists say the health of the yeast improved greatly after exposure to the chemical extracts.
      changed to develop symptoms of Alzheimer's.
     They found that when the flies were given brown seaweed extract, their lifespans increased by two days. Prickly pear helped the insects live four days longer.
     That may not sound like a long time. However, that one day in the life of a fruit fly is equal to one human year.
     Researchers also noted that movement in some diseased insects improved.
     They reported their findings in the journal Neuroscience Letters.
     The best way to fight neurodegenerative diseases
     Researchers say that the sticky plaques in both Alzheimer's and Parkinson's diseases appear to form through the same biological pathways. Targeting these pathways, they say, is the best way to fight the diseases.
     The lead author of the study is Ruben Cauchi of the University of Malta's Center for Molecula in health foods and some cosmetics. So, they are very safe.
      as so-called "fountain of youth" products.
     And that's the Health & Lifestyle report.
