BACKGROUND Mutations in the spastin gene are the commonest cause of hereditary spastic paraparesis (HSP), accounting for up to 40% of autosomal dominant cases. The phenotype associated with HSP due to mutation in the spastin gene (SPG4) tends to be pure HSP. OBJECTIVE To characterize in more detail the genetic and phenotypic characteristics of SPG4 by(More)
The hereditary spastic paraplegias (HSP) are a heterogeneous group of conditions in which the main feature is a progressive spastic paraparesis. Mutations in the receptor expression enhancing protein 1 (REEP1) gene have recently been reported to be associated with an autosomal dominant HSP phenotype (SPG31). The objective of this study was to identify the(More)
BACKGROUND Lithium has neuroprotective effects in cell and animal models of amyotrophic lateral sclerosis (ALS), and a small pilot study in patients with ALS showed a significant effect of lithium on survival. We aimed to assess whether lithium improves survival in patients with ALS. METHODS The lithium carbonate in amyotrophic lateral sclerosis (LiCALS)(More)
AIMS Loss of nuclear TDP-43 characterizes sporadic and most familial forms of amyotrophic lateral sclerosis (ALS). TDP-43 (encoded by TARDBP) has multiple roles in RNA processing. We aimed to determine whether (1) RNA splicing dysregulation is present in lower motor neurones in ALS and in a motor neurone-like cell model; and (2) TARDBP mutations (mtTARDBP)(More)
Mutations in the transactive response DNA binding protein-43 (TARDBP/TDP-43) gene, which regulates transcription and splicing, causes a familial form of amyotrophic lateral sclerosis (ALS). Here, we characterize and report the first tardbp mutation in zebrafish, which introduces a premature stop codon (Y220X), eliminating expression of the Tardbp protein.(More)
Chronic idiopathic axonal polyneuropathy (CIAP) is a term describing neuropathies with both sensory and motor involvement in a length dependant distribution where neurophysiology reveals axonal damage, neuropathy onset is insidious and shows slow or no progression of the disease over at least 6 months with no aetiology being identified despite appropriate(More)
OBJECTIVE To determine whether inclusion of vitamin E into kidney storage solutions protects metabolism and tubular ultrastructure of stored rat kidney. METHODS Rat kidneys were flush stored in Marshall's Citrate (MC) and MC + vitamin E (25% of LD 50 and 50% of LD 50) for 24 hours at 0 degrees C. After storage kidney slices were tested for gluconeogenesis(More)
