Dyskinesias are disorders of the central nervous system that result in involuntary movements in a fully conscious individual. This report describes a disorder in a five-year-old male neutered bichon frise characterised by episodic involuntary skeletal muscle activity with normal levels of consciousness that bears some similarity to the previously described(More)
The age-associated decrease in the efficiency of CNS remyelination has clear implications for recovery from demyelinating diseases such as multiple sclerosis (MS) that may last for several decades. Developing strategies to reverse the age-associated decline requires the identification of how the regenerative process is impaired. We addressed whether(More)
Glial growth factor-2 (GGF-2) is a neuronally derived isoform of neuregulin shown in vitro to promote proliferation and survival of oligodendrocytes, the myelinating cells of the CNS. Enhanced remyelination has been demonstrated in vivo following systemic delivery of human recombinant GGF-2 (rhGGF-2) in experimental autoimmune encephalomyelitis (EAE).(More)
To assess the effects of sex on CNS remyelination, demyelinating lesions were induced by injection of ethidium bromide into the caudal cerebellar peduncle of Sprague-Dawley rats divided into the following 8 groups: young adult male, young adult female, old adult male and old adult female and each of these in which the gonads had been removed 4 weeks prior(More)
It has been hypothesized that the progressive failure of remyelination in chronic multiple sclerosis is, in part, the consequence of repeated episodes of demyelination at the same site, eventually depleting oligodendrocyte progenitor cells (OPCs) and exhausting the remyelinating capacity. We investigated the effect of previous focal, ethidium(More)
The domestic dog (Canis familiaris) segregates more naturally-occurring diseases and phenotypic variation than any other species and has become established as an unparalled model with which to study the genetics of inherited traits. We used a genome-wide association study (GWAS) and targeted resequencing of DNA from just five dogs to simultaneously map and(More)
In a retrospective evaluation of 654 canine and feline myelograms, 58 were found to have been complicated by injection of the contrast medium into the subdural space. The medium was present predominantly dorsal to the spinal cord, with a sharp dorsal border and an undulating ventral border. Confirmation that this myelographic appearance was due to subdural(More)
BACKGROUND The brainstem auditory-evoked response (BAER) is currently the standard evaluation method of hearing in dogs. In asymmetrical hearing loss in human patients, simultaneous presentation of masking noise to the nontest ear is routinely performed during BAER to eliminate the crossover effect. HYPOTHESIS The crossover effect occurs during canine(More)
This article outlines the consensus proposal on diagnosis of epilepsy in dogs by the International Veterinary Epilepsy Task Force. The aim of this consensus proposal is to improve consistency in the diagnosis of epilepsy in the clinical and research settings. The diagnostic approach to the patient presenting with a history of suspected epileptic seizures(More)
Dogs with epilepsy are among the commonest neurological patients in veterinary practice and therefore have historically attracted much attention with regard to definitions, clinical approach and management. A number of classification proposals for canine epilepsy have been published during the years reflecting always in parts the current proposals coming(More)
