Boston, MA (PRWEB) January 16, 2013
Doctors Health Press, a division of Lombardi Publishing Corporation and publisher of various natural health newsletters, books, and reports, including the popular online Doctors Health Press e-Bulletin, is reporting on a new study out of the University of California, Los Angeles (titled “Pesticides and Parkinson’s: UCLA researchers uncover further proof of a link”) that has found a link between certain pesticides used to protect plant life—and Parkinson’s disease.
As Doctors Health Press e-Bulletin notes in its recent article (http://www.doctorshealthpress.com/general-health-2/even-more-harmful-effects-from-pesticides-discovered), paraquat, maneb, and ziram are common chemicals sprayed in the U.S. (especially California) and have been tied to increases in Parkinson’s. This was not only among people who work on the farms, but also in those who lived or worked nearby.
As the article “Even More Harmful Effects from Pesticides Discovered” reports, this new study now adds another pesticide to the equation: benomyl. It has been a decade since the U.S. banned its use, but researchers have found its toxic effects still linger—and it, too, is linked to Parkinson’s.
The Doctors Health Press e-Bulletin article explains that researchers believe exposure to benomyl triggers cellular changes that can pave the road to Parkinson’s. It stops one particular enzyme from trapping “DOPAL,” which is a natural toxin in the brain. Without that enzyme, DOPAL can build up, damage neurons, and raise the risk for Parkinson’s. This discovery could actually lead to positive developments: like whether protecting that enzyme could slow the progression of the disease in patients already diagnosed with Parkinson’s.
The article notes that millions live with Parkinson’s symptoms, which include slow speech and movements, tremors, and rigidity. Researchers have found certain genetic links, but the article states genetics are only a minor risk factor. So, researchers now believe environmental factors—like pesticides—play a big role in Parkinson’s.
Doctors Health Press e-Bulletin reports that benomyl was widely used in the U.S. for 30 years until a toxic link to liver cancer, brain malformations, and problems with the reproductive system was discovered. It was banned in 2001. Still, the researchers wanted to explore the pesticide for potential long-term effects. Under the microscope, they confirmed that the pesticide damaged or destroyed neurons. They found this again in a fish model—the pesticide damaged important “dopaminergic” neurons, while leaving others untouched.
The Doctors Health Press e-Bulletin article concludes that this health breakthrough is big news, because until now, scientists have targeted one specific protein known to lead to Parkinson’s. But looking into this pesticide has led researchers to an enzyme that is another target entirely to try and stop this disease.
