Oxidative stress has been reported to be a common underlying mechanism in the pathogenesis of many neurodegenerative disorders such as Alzheimer, Huntington, Creutzfeld-Jakob, and Parkinson disease. Despite the increasing number of articles showing a correlation between oxidative damage and neurodegeneration little is known about the genetic elements that(More)

Friedreich ataxia (FA), the most common form of hereditary ataxia, is caused by a deficit in the mitochondrial protein frataxin. While several hypotheses have been suggested, frataxin function is not well understood. Oxidative stress has been suggested to play a role in the pathophysiology of FA, but this view has been recently questioned, and its link to(More)
BACKGROUND Friedreich's ataxia (FA), the most frequent form of inherited ataxias in the Caucasian population, is caused by a reduced expression of frataxin, a highly conserved protein. Model organisms have contributed greatly in the efforts to decipher the function of frataxin; however, the precise function of this protein remains elusive. Overexpression(More)
Function of the melon necrotic spot virus (MNSV) genome-encoded proteins (p29, p89, p7A, p7B and p42) has been studied. Protein-expression mutants of an infectious, full-length cDNA clone of a Spanish MNSV-Al isolate and a recombinant green fluorescent protein (GFP)-expressing virus were used in infection bioassays on melon plants. Results revealed that p29(More)
Drosophila melanogaster has contributed significantly to the understanding of disease mechanisms in Parkinson's disease (PD) as it is one of the very few PD model organisms that allow the study of age-dependent behavioral defects, physiology and histology, and genetic interactions among different PD-related genes. However, there have been contradictory(More)
cells and muscles as tools to study neurodegenerative diseases in Drosophila melanogater " Summary: Drosophila melanogaster has contributed significantly to the understanding of disease mechanisms in Friedreich's ataxia (FRDA) and Parkinson's disease (PD) as it is one of the very few model organisms that allow the study genetic interactions among(More)
A context free grammar (CFG) is a set of symbols and productions used to define a context free language. We present an algorithm which, given a CFG and a string α, decides whether a string of the form βαγ belongs to the language or not. There is a wide variety of applications where deciding if a string belongs to the defined language has relevance but, due(More)
