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)
MRPS22 gene defect is a very rare newly discovered mitochondrial disorder. We report a 4-month-old severely affected male infant with MRPS22 mutation. Whole exome sequencing revealed a novel homozygous splicing mutation c.339 + 5 G > A in MRPS22 gene. He has mild dysmorphism, hypotonia, developmental delay but not hypertrophic cardiomyopathy and tubulopathy(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)
BACKGROUND We aimed to investigate the reliability of the Alvarado score (AS) in determining acute appendicitis and the different parameters that affect the AS. METHODS Three hundred and thirteen patients suspected of acute appendicitis (AA) aged 18-70 years were included in this study. Patient data including AS calculated from emergency services and at(More)
BACKGROUND The purpose of the present paper was to investigate the prevalence of prothrombotic risk factors associated with hemiplegic cerebral palsy (CP). METHODS Twenty-three hemiplegic CP patients were tested for inherited and acquired prothrombotic risk factors, except methylene tetrahydrofolate reductase (MTFR) polymorphism. RESULTS A total of(More)
Chemical entities designed to noncovalently interact with predetermined partners have fashioned a new paradigm in chemical biology. Fluorocarbons are extremely promising as supramolecular synthons toward these objectives. Bioorthogonal noncovalent interactions provide a way to modulate self-assembled systems in environments where such control has hitherto(More)
Some epithelial cancers can be induced to revert to quiescent differentiated tissue when combined with embryonic mesenchyme; however, the mechanism of this induction is unknown. Here we combine tissue engineering, developmental biology, biochemistry and proteomics approaches to attack this problem. Using a synthetic reconstitution system, we show that(More)
Fibronectin (FN) assembly into extracellular matrix is tightly regulated and essential to embryogenesis and wound healing. FN fibrillogenesis is initiated by cytoskeleton-derived tensional forces transmitted across transmembrane integrins onto RGD binding sequences within the tenth FN type III (10FNIII) domains. These forces unfold 10FNIII to expose cryptic(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)
