BACKGROUND Duchenne and Becker muscular dystrophies are allelic disorders arising from mutations in the dystrophin gene. Duchenne muscular dystrophy is characterised by an absence of functional protein, while Becker muscular dystrophy is usually caused by in-frame deletions allowing synthesis of some functional protein. Treatment options are limited, and we(More)
The structure and infectivity of the oocysts of a new species of Cryptosporidium from the feces of humans are described. Oocysts are structurally indistinguishable from those of Cryptosporidium parvum. Oocysts of the new species are passed fully sporulated, lack sporocysts. and measure 4.4-5.4 microm (mean = 4.86) x 4.4-5.9 microm (mean = 5.2 microm) with a(More)
Antisense oligonucleotides (AOs) can be used to redirect dystrophin pre-messenger RNA (mRNA) processing, to remove selected exons from the mature dystrophin mRNA, to overcome nonsense mutations, and/or restore the reading frame. Redundancy within the dystrophin protein allows some domains to be removed without seriously compromising function. One of the(More)
Protein-truncating mutations in the dystrophin gene lead to the most common childhood form of muscle wasting, Duchenne muscular dystrophy. Becker muscular dystrophy, a condition that typically arises from dystrophin gene lesions that do not disrupt the reading frame, clearly indicates that substantial domains of the dystrophin protein are not essential.(More)
Duchenne and Becker muscular dystrophies are allelic disorders arising from mutations in the dystrophin gene. Duchenne muscular dystrophy is characterized by an absence of functional protein, whereas Becker muscular dystrophy, commonly caused by in-frame deletions, shows synthesis of partially functional protein. Anti-sense oligonucleotides can induce(More)
Within the coccidia, morphological features of the oocyst stage at the light microscope level have been used more than any other single characteristic to designate genus and species. The aim of this study was to conduct morphometric analysis on a range of Cryptosporidium spp. isolates and to compare morphological data between several genotypes of C. parvum(More)
Antisense oligonucleotide (AO) manipulation of pre-mRNA splicing of the dystrophin gene is showing promise in overcoming Duchenne muscular dystrophy (DMD)-causing mutations. To date, this approach has been limited to studies using animal models or cultured human muscle cells, and evidence that AOs can induce exon skipping in human muscle has yet to be(More)
We give a survey of results on global stability for deterministic compartmental epidemiological models. Using Lyapunov techniques we revisit a classical result, and give a simple proof. By the same methods we also give a new result on differential susceptibility and infectivity models with mass action and an arbitrary number of compartments. These models(More)
BACKGROUND Duchenne muscular dystrophy is a fatal genetic disorder caused by dystrophin gene mutations that result in premature termination of translation and the absence of functional protein. Despite the primary dystrophin gene lesion, immunostaining studies have shown that at least 50% of DMD patients, mdx mice and a canine model of DMD have rare(More)
Genetic and phylogenetic characterization of Cryptosporidium isolates at two loci (18S rRNA gene and heat shock gene) from both Australian and United States dogs demonstrated that dog-derived Cryptosporidium isolates had a distinct genotype which is conserved across geographic areas. Phylogenetic analysis provided support for the idea that the "dog"(More)
