This paper provides detailed information on the distribution of neuropeptide tyrosine (neuropeptide Y; NPY) immunoreactive neurons and fibers in the hippocampal region of eight neuropathologically confirmed cases of Alzheimer's-type dementia (ATD) at postmortem. These neuronal networks are detected by a polyclonal antibody raised against the unconjugated(More)
The alpha 1 subunit of the cardiac L-type Ca2+ channel (alpha 1C) is one of the many alternatively spliced products of a single gene that is expressed in a number of excitable tissues. Sequence comparison indicates that the amino terminus is a site of significant structural diversity. To explore the role of the amino terminus of alpha 1C in expression and(More)
Despite its widespread availability and known safety and efficacy, a therapy with intravenous thrombolysis is still undergiven. We aimed to identify whether nationwide quality projects--like the stroke registry in Austria--as well as online benchmarking and predefined target values can increase rates of thrombolysis. Therefore, we assessed 6,394 out of(More)
BACKGROUND In 2008 the Austrian Task Force for Neuromyelitis Optica (NMO) started a nation-wide network for information exchange and multi-centre collaboration. Their aim was to detect all patients with NMO or NMO spectrum disorders (NMO-SD) in Austria and to analyse their disease courses and response to treatment. METHODS (1) As of March 2008, 1957 serum(More)
Two specific silver-staining methods demonstrating either extracellular amyloid and/or precursors of amyloid or intraneuronal neurofibrillary changes were used to examine cerebellar pathology in cases of presenile and senile dementia of the Alzheimer type, cases of Down's syndrome, and non-demented controls. The sensitivity of the techniques permitted(More)
Neuromyelitis optica (NMO) is characterised by a particular pattern of the optic nerves and the spinal cord. Long-term MRI follow-up studies of spinal NMO lesions are rare, or limited by short observation periods. In nine patients with definite NMO or recurrent longitudinally extensive transverse myelitis (LETM) with NMO-IgG serum antibodies, repeated MRI(More)
Neurons identified by their immunoreactivity with antisera against neuropeptide Y (NPY) were studied in three selected areas of the cerebral cortex in brains from controls and in senile dementia of the Alzheimer type (ATD). Changes were more profound in temporal cortex than in parietal cortex, and more severe in parietal cortex than in frontal cortex,(More)
The detailed distribution of neuropeptide tyrosine (neuropeptide Y; NPY) immunoreactive neurons and fibers is given for the normal human hippocampus. These neuronal elements are detected by a polyclonal antibody raised against the unconjugated peptide and controls were obtained by using liquid phase absorption immunocytochemistry. The description covers the(More)
We measured brain activities with a whole head magnetoencephalograph (MEG) to investigate the influence of a background odor on alphabetical encoding of words in 20 healthy volunteers (10 females). Odor stimulation and control air stimulation were both accomplished with a computer-controlled olfactometer by providing permanent stimulation conditions.(More)
