UNLABELLED In this study, we analyzed the ABCD1 gene in X-linked adrenoleukodystrophy (X-ALD) patients and relatives from 38 unrelated families from South America, as well as phenotypic proportions, survival estimates, and the potential effect of geographical origin in clinical characteristics. METHODS X- ALD patients from Brazil, Argentina and Uruguay(More)
BACKGROUND Neurologic impairments in female heterozygotes for X-linked Adrenoleukodystrophy (X-ALD) are poorly understood. Our aims were to describe the neurological and neurophysiological manifestations of a cohort of X-ALD heterozygotes, and to correlate them with age, disease duration, mutations, X-inactivation and serum concentrations of a marker of(More)
X-linked adrenoleukodystrophy heterozygote women can present adult onset myeloneuropathy and little is known about its natural history. We aimed to describe the progression rate of the neurological impairment in the prospective follow-up of our cohort and to look for prognostic factors. The neurological scales Japanese Orthopaedic Association (JOA) and(More)
PURPOSE To report the clinical and neuroimaging, central nervous system (CNS) findings of patients with Fabry disease (FD) during 24 months of enzyme replacement therapy (ERT) with agalsidase-alpha. METHOD Eight patients were included. Six completed 24 months of ERT. Clinical and magnetic resonance imaging (MRI) data were obtained at 0, 12 and 24 months(More)
New N-p-chloro-, N-p-bromo-, and N-p-nitrophenylazobenzylchitosan derivatives, as well as the corresponding azophenyl and azophenyl-p-sulfonic acids, were synthesized by coupling N-benzylvchitosan with aryl diazonium salts. The synthesized molecules were analyzed by UV-Vis, FT-IR, 1H-NMR and 15N-NMR spectroscopy. The capacity of copper chelation by these(More)
Bioresorbable electrospun fibres have highly functional features that can preserve drug efficacy, avoiding premature degradation, and control drug release rates over long periods. In parallel, it is known that Alzheimer’s disease (AD) has been linked to impaired insulin signalling in the brain. Glucagon-like peptide 1 (GLP-1) analogues have beneficial(More)
The Fabry disease is caused by mutations in the gene (GLA) that encodes the enzyme α-galactosidase A (α-Gal A). More than 500 pathologic variants of GLA have already been described, most of them are family-specific. In southern Brazil, a frequent single-base deletion (GLA 30delG) was identified among four families that do not recognize any common ancestral.(More)
The spinocerebellar ataxia type 2 (SCA2) is a rare autosomal dominant neurodegenerative disease caused by expansions of a CAG repeat tract at ATXN2 gene. These repeats range from 22 to 31 CAG in normal alleles and from 32–34 to 64 and more, in expanded alleles. ATXN2 expansion accounts for around 50 % of the variability in age at onset (AO) of symptoms [1].(More)
