Nogo-A is an important axonal growth inhibitor in the adult and developing CNS. In vitro, Nogo-A has been shown to inhibit migration and cell spreading of neuronal and nonneuronal cell types. Here, we studied in vivo and in vitro effects of Nogo-A on vascular endothelial cells during angiogenesis of the early postnatal brain and retina in which Nogo-A is(More)
AIM The goal of this case-control study was to identify the significance of certain risk factors for epilepsy in Turkey. METHOD A total of 805 cases, aged 1-16 years, followed-up for epilepsy at the Pediatric Neurology Department and a control group consisting of 846 age-matched cases without epilepsy were included in the study. The risk factors examined(More)
UNLABELLED DYT-1 dystonia is the most common primary dystonia seen in childhood. It is an autosomal dominantly inherited disorder caused by deletion of a GAG triplet in exon 5 of the DYT1 gene. It characteristically starts in a distal limb during late childhood, subsequently spreads to involve other body regions sparing oromandibular muscles. However,(More)
Ethylmalonic encephalopathy (EE) is an autosomal recessive devastating metabolic disorder affecting the brain, gastrointestinal tract, peripheral vessels and rarely the other vascular organs. We report a 10-month-old girl who presented as a meningococcemia clinic but later diagnosed ethylmalonic encephalopathy. Molecular analyses revealed a homozygous c.554(More)
Chronic inflammatory demyelinating neuropathy, a treatable immune-mediated disease of the peripheral nervous system is less common in childhood compared to adults. Despite different sets of diagnostic criteria, lack of a reliable biologic marker leads to challenges in diagnosis, follow-up and treatment. Our first aim was to review clinical presentation,(More)
PURPOSE Subacute sclerosing panencephalitis (SSPE) is a progressive, lethal disease. Brain histopathology in certain SSPE patients shows, neurofibrillary tangles composed of abnormally phosphorylated, microtubule-associated protein tau (PHF-tau). Because the, phosphorylation of tau is inhibited by insulin and insulin-like growth factor-1 (IGF-1), we(More)
OBJECTIVE We performed diffusion tensor imaging (DTI) and magnetic resonance spectroscopy (MRS) studies in a group of patients with subacute sclerosing panencephalitis (SSPE) in order to estimate the pathologic process underlying the phenotypic variability. METHODS Patients with SSPE who had MRI including DTI and MRS examinations were evaluated according(More)
Neurofibrillary tangles (NFTs) have been shown in 20% of subacute sclerosing panencephalitis (SSPE) cases. NFTs contain paired helical filaments formed by hyperphosphorylated tau. The intraneuronal tau metabolism and the rate of formation of paired helical filaments can be regulated by interactions between tau and isoforms of Apolipoprotein E (Apo E). Tau(More)
