Dementia with Lewy bodies (DLB) is a neuropsychiatric disease associated with extrapyramidal features which differ from those of Parkinson's disease, including reduced effectiveness of L-dopa and severe sensitivity reactions to neuroleptic drugs. Distinguishing Alzheimer's disease from DLB is clinically relevant in terms of prognosis and appropriate(More)
OBJECTIVE To observe the effects of introducing an acute pain service to the general surgical wards of a large teaching hospital. DESIGN A study in seven stages: (1) an audit of current hospital practice succeeded by the sequential introduction to the general surgical wards of (2) pain assessment charts; (3) an algorithm to allow more frequent use of(More)
The human striatum, which receives dopaminergic innervation from the substantia nigra and ventral tegmental area (cell groups A8, A9 and A10), has structural and functional subdivisions both rostrocaudally and dorsoventrally. These relate to motor and non-motor origins of cortical projections and the specific areas of the substantia nigra and ventral(More)
Neuronal nicotinic receptors have been implicated in schizophrenia on the basis of the high incidence of tobacco smoking in patients, abnormalities in cytisine and alpha-bungarotoxin (alphaBGT) binding in the hippocampus, and linkage between auditory P50 deficits and the region of chromosome 15 coding the alpha7 subunit. In another disease associated with(More)
The effects of cytotoxic lesions in either the anterior cingulate cortex or the retrosplenial cortex were compared with those of fornix lesions on three tests of spatial memory. Two of the tasks, delayed nonmatching-to-position and spatial reversal learning, were tested in an automated apparatus. The third task, forced alternation, was tested in a T-maze.(More)
BACKGROUND High serum alanine aminotransferase (ALT) levels have been associated with increased risk of diabetes and with increased mortality, but associations of variations of ALT in the normal range with outcomes have been less well studied. METHODS We studied the relationship between ALT, mortality and cardiovascular events in the West of Scotland(More)
Brain tissue obtained at autopsy continues to provide unique opportunities in current dementia research. Not only is tissue analysis still essential for diagnosis, but investigation of neurochemical pathology, at a level of resolution beyond current in vivo imaging, continues to provide new insights into the involvement of neurotransmitter signalling(More)
Groups of rats were trained on one of two variants of an operant memory task which allows strength of memory (accuracy), bias and response rates to be measured directly. In matching to position (MTP), one of two retractable response levers appeared at random as the sample. A response caused the lever to retract and this was followed by a delay (0-64 s)(More)
Striatal nicotinic acetylcholine receptors with high affinity for nicotinic agonists are involved with the release of a number of neurotransmitters, including dopamine. Previous findings as to whether these receptors are changed in Parkinson's disease and Alzheimer's disease are inconsistent and no previous investigations have focused on these receptors in(More)
INTRODUCTION Central-venous-catheter (CVC)-related bloodstream infection (CRBSI) is a complication of intensive care stay which can have important adverse consequences for both patient and institution. There are a number of evidence-based interventions that reduce CRBSI, but it is recognised that consistently applying the best evidence every time is a(More)
