Research ArticleOpen accessIn the abstractEvidence of Mitochondrial Dysfunction in Autism and Implications for TreatmentDaniel A. Rossignol, J. Jeffrey BradstreetClassical mitochondrial diseases occur in a subset of individuals with autism and are usually caused by genetic anomalies or mitochondrial respiratory pathway deficits. However, in many cases of autism, there is evidence of mitochondrial dysfunction (MtD) without the classic features associated with mitochondrial disease. MtD appears to be more common in autism and presents with less severe signs and symptoms. … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 2 · 30 Jun 2008 · 16,373 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Novel Rodent Model of Autism: Intraventricular Infusions of Propionic Acid Increase Locomotor Activity and Induce Neuroinflammation and Oxidative Stress in Discrete Regions of Adult Rat BrainDerrick F. MacFabe, Karina Rodríguez-Capote, Jennifer E. Hoffman et al.Innate neuroinflammatory changes, increased oxidative stress and disorders of glutathione metabolism may be involved in the pathophysiology of autism spectrum disorders (ASD). Propionic acid (PPA) is a dietary and gut bacterial short chain fatty acid which can produce brain and behavioral changes reminiscent of ASD following intraventricular infusion in rats. Adult Long-Evans rats were given intraventricular infusions of either PPA … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 2 · 30 Jun 2008 · 12,613 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOxidative Stress in Autism: Elevated Cerebellar 3-nitrotyrosine LevelsElizabeth M. Sajdel-Sulkowska, Boguslaw Lipinski, Herb Windom et al.It has been suggested that oxidative stress and/or mercury compounds play an important role in the pathophysiology of autism. This study compared for the first time the cerebellar levels of the oxidative stress marker 3-nitrotyrosine (3-NT), mercury (Hg) and the antioxidant selenium (Se) levels between control and autistic subjects. Tissue homogenates were prepared in the presence of protease inhibitors from … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 2 · 30 Jun 2008 · 17,119 accessesView PDF Cite

Research ArticleOpen accessIn the abstractColourimetric Determination of Phospholipase Activities in Balamuthia mandrillarisSyed Razi HaiderBalamuthia mandrillaris is a recently identified protozoan pathogen that can cause fatal granulomatous encephalitis however the pathogenesis and pathophysiology associated with Balamuthia encephalitis remain unclear. We have recently isolated B. mandrillaris from a 33-years old male who died of encephalitis. Using this isolate, we demonstrated for the first time that B. mandrillaris exhibited phospholipase activities. More specifically, B. mandrillaris exhibited … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 30 Sep 2007 · 6,771 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGranulomatous Amoebic Encephalitis: Clinical Diagnosis and ManagementNaveed Ahmed KhanGranulomatous amoebic encephalitis (GAE) is a serious human disease with fatal consequences. With the mortality rate of more than 90%, it is not surprising that the majority of GAE infections are identified at the post-mortem stage. The most distressing aspect is that the high level of mortality is attributed to lack of awareness. Early diagnosis with aggressive treatment can lead … …American Journal of Infectious Diseases, Vol. 1, Issue 2 · 30 Jun 2005 · 7,187 accessesView PDF Cite
