The findings were published today in the New England Journal of Medicine. http://www.physorg.com/news175364749.html Medicine & Health Wed, 21 Oct 2009 17:27:08 EST news175364749 Both genetic and pathologic data indicate a role for the neuronal protein alpha-synuclein in Parkinson disease. Previous studies have indicated that phosphorylation of alpha-synuclein at amino acid 129 (Ser129) is a key event in alpha-synuclein-mediated nerve cell toxicity. However, Mel Feany and colleagues, at Brigham and Women's Hospital, Boston, have now identified a counterbalancing role in nerve cell protection for phosphorylation of alpha-synuclein amino acid 125 (Tyr125). http://www.physorg.com/news174591588.html Medicine & Health Mon, 12 Oct 2009 19:40:01 EST news174591588 Researchers from Boston University School of Medicine (BUSM) have identified genes which may influence the onset age of Parkinson's Disease (PD). The findings, which currently appear on-line in BMC Medical Genetics, are the first to identify genes contributing to the variation in onset age and may help identify mechanisms and therapeutic targets capable of delaying symptoms. http://www.physorg.com/news174139192.html Medicine & Health Wed, 07 Oct 2009 13:00:38 EST news174139192 A Michigan hospital is embarking on a research study for advanced Parkinson's disease using a state-of-the-art treatment called gene transfer. http://www.physorg.com/news174061732.html Medicine & Health Tue, 06 Oct 2009 15:37:38 EST news174061732 Drivers with mild to moderate Parkinson's disease may be at higher risk of crashes on foggy days and other times of low visibility.

The cells in the so-called substantia nigra, which contain the dark pigment neuromelanin, are affected. It is also known that the iron content of these cells increases during the course of Parkinson's disease. http://www.physorg.com/news169899879.html Medicine & Health Wed, 19 Aug 2009 11:50:04 EST news169899879 (PhysOrg.com) -- Protein function and gene expression are often regulated by reversible modifications of already existing proteins. Scientists from the Max Planck Institute of Biochemistry and the University of Copenhagen have now been able to prove that the reversible attachment of acetyl groups influences virtually all functions of human cells and therefore has a much greater importance than previously assumed. Whether it is cell division, signal transduction or ageing - all these processes are affected by acetyl groups acting as molecular switches. Therefore, these switches may prove to be a crucial factor in the development of new therapies against diseases like cancer, Alzheimer`s or Parkinson`s. http://www.physorg.com/news169738654.html Chemistry Mon, 17 Aug 2009 15:10:28 EST news169738654 Jichi Medical University has succeeded in restoring the motor function of patients suffering from Parkinson's disease by injecting their brains with a virus with a built-in gene that has an enzyme to produce dopamine, it has been learned. http://www.physorg.com/news169483653.html Medicine & Health Fri, 14 Aug 2009 16:00:01 EST news169483653 At least one strain of the H5N1 avian influenza virus leaves survivors at significantly increased risk for Parkinson's disease and possibly other neurological problems later in life, according to new research from St. Jude Children's Research Hospital. http://www.physorg.com/news169137452.html Medicine & Health Mon, 10 Aug 2009 16:00:04 EST news169137452 July 13, 2009 - People with Parkinson's disease have significantly higher blood levels of a particular pesticide than healthy people or those with Alzheimer's disease, researchers at UT Southwestern Medical Center have found. http://www.physorg.com/news166729972.html Medicine & Health Mon, 13 Jul 2009 22:00:01 EST news166729972 Eye movement tests developed by Queen's University researchers to aid in understanding childhood brain development and healthy aging may also help in the diagnosis of Attention Deficit Hyperactivity Disorder and detecting the early onset of Parkinson's disease.
