objective sub acute sclerosing pan encephalitis (sspe), a progressive neurological disorder characterized by inflammation of the brain (encephalitis), is the result of an inappropriate immune response to the measles virus or measles vaccination. sspe usually develops 2 to 10 years after the original viral attack. some of the major signs and symptoms are mental deterioration, jerky movements, an...

Importation of animals or animal products cannot take place without some element of risk. Risk analysis is a blend of art and science and is a tool intended to provide decision-makers with an objective, repeatable and defensible assessment of the risks posed by a particular import proposal. Risk analysis comprises risk identification, risk assessment, risk management and risk communication. Exa...

Neuronal population oscillations at a variety of frequencies can be readily seen in electroencephalographic (EEG) as well as local field potential recordings in many different species. Although these brain rhythms have been studied for many years, the methods for identifying discrete oscillatory epochs are still widely variable across studies. The "better oscillation detection" (BOSC) method ap...

The two most attractive current hypotheses concerning the aetiology of disseminated (multiple) sclerosis (MS) are those of (1) an 'autoimmune' process, analogous to experimental allergic encephalitis, or (2) an infection, for which the 'slow virus diseases' of the central nervous system represent a possible model. Experimental data have been advanced favouring each hypothesis, and it is in fact...

We introduce a new solid-state NMR method, which uses very slow sample rotation to visualize NMR spectra whose width exceeds feasible spectrometer bandwidths. It is based on the idea that if we reorient a tensor by a known angle about a known axis, the shifts in the NMR frequencies observed across the spectral width allow us to reconstruct the entire tensor. Called STREAQI (Slow Turning Reveals...

Slow breathing training reduces resting blood pressure, probably by modifying central autonomic control, but evidence for this is lacking. The pressor response to static handgrip exercise is a measure of autonomic control and the aim of this study was to determine whether slow breathing training modulates the pressor responses to exercise of untrained muscles. Twenty hypertensive patients train...

The major slow viral infections discovered in man manifest themselves in chronic neurological disease. Studies of these diseases have allowed a better understanding of the mechanisms of virus persistence in the central nervous system. Findings are summarized from recent investigations on such slow viral infections as subacute sclerosing panencephalitis, progressive multifocal leukoencephalopath...
