Iron banded worms drying out of blood could be linked to Parkinson's and Alzheimer's

02-09-2008 · EurekAlert!

Researchers at the University of Warwick and the Indian Institute of Technology Kanpur have discovered that the mechanism that we rely on to transport iron safely through our blood can collapse into a state which grows long worm-like "fibrils" banded by lines of iron rust. This process could provide the first insight into how iron gets deposited in the brain to cause some forms of Parkinson's & Alzheimer's and Huntington's diseases.

  1. Separating the brain's 'bad' from 'good' iron
    08-23-2007 · EurekAlert!
    Duke University chemists are developing ways to bind up iron in the brain to combat the neurological devastation of Parkinson's and Alzheimer's diseases. The key is to weed out potentially destructive forms of iron that generate harmful free radicals while leaving benign forms of iron alone to carry out vital functions in the body.

  2. Researchers link metal ions to neurodegenerative disease
    08-06-2007 · EurekAlert!
    Researchers have defined for the first time how metal ions bind to amyloid fibrils in the brain in a way that appears toxic to neurons. Amyloid fibrils are linked to the development of neurodegenerative diseases such as Alzheimer's, Parkinson's and Creutzfeldt-Jakob. Although metal ions, most notably copper, can bind to amyloid in several specific ways, the researchers found that only one way appears toxic.

    In a new, large-scale, prospective study exploring the link between levels of urate in the blood and risk of Parkinson’s disease, researchers from the Harvard School of Public Health (HSPH) have found that high levels of urate are strongly associated with a reduced risk of the disease.

    11-05-2007 · EurekAlert!
    Alzheimer's disease may progress more rapidly in people with high blood pressure or a form of irregular heartbeat, atrial fibrillation, according to results of a Johns Hopkins study published in the Nov. 6, 2007, issue of Neurology. The findings suggest that treating these conditions may also slow memory loss in people with AD.

    11-02-2007 · EurekAlert!
    A new study led by Children's Hospital Oakland Research Institute senior scientist, Elizabeth Theil, PhD, is the first to suggest that a small protein or heptapeptide could be used to accelerate the removal of iron from ferritin. The results of this study may help scientists develop new medications that dramatically improve the removal of excess iron in patients diagnosed with blood diseases such as B-Thalassemia (Cooley's anemia) or sickle cell disease.

    11-20-2007 · EurekAlert!
    The extra blood volume produced in the obese may so dilute levels of a telltale protein produced by prostates that the popular PSA test may be essentially useless for diagnosing prostate cancer in men carrying extra pounds, a new study in the Journal of the American Medical Association suggests.

  7. Asexual worm quickly adapts to soil contamination
    05-14-2007 · EurekAlert!
    Soil contaminants lead to rapid genetic adaptations in the nematode Acrobeloides nanus. The worms from contaminated soil live longer and lay more eggs under polluted conditions than the worms from unpolluted soil. Dutch-sponsored researcher Agnieszka Doroszuk demonstrated this in her study into the long-term effects of environmental pollution on soil organisms.

  8. Protein inhibitor tangles with Alzheimer's disease
    02-15-2007 · EurekAlert!
    A hallmark of Alzheimer's disease (AD) is the abnormal accumulation of phosphorylated forms of a protein known as tau. In a new study, Mayo Clinic researchers have now shown in mice that a drug that inhibits the function of the protein Hsp90 (EC102) reduces the amount of phosphorylated tau in the brain. Unlike many drugs, EC102 is able to cross the blood-brain barrier, making it a highly promising therapeutic candidate for AD.

    Women who use hormone therapy before the age of 65 could cut their risk of developing Alzheimer's disease or dementia. This possibility is raised by research that will be presented at the American Academy of Neurology's 59th Annual Meeting in Boston, April 28-May 5, 2007.
