Ultrastructural quantitative analysis was undertaken to determine whether any age-related synaptic changes occur in cortical layer 1 of the human precentral motor gyrus (Brodmann's area 4) and postcentral somatosensory gyrus (Brodmann's area 3). Immersion fixed, osmicated, uranyl acetate/lead citrate stained (OsUL) preparations of autopsied brains were(More)
A multicentre study of computer aided diagnosis for patients with acute abdominal pain was performed in eight centres with over 250 participating doctors and 16,737 patients. Performance in diagnosis and decision making was compared over two periods: a test period (when a small computer system was provided to aid diagnosis) and a baseline period (before the(More)
Ultrastructural observation of the molecular layer of the parietal cortex of rats, aged 3, 6, 10 and 17 months, revealed various atypical synaptic profiles besides typical synapses. The atypical synapses were frequently in the vicinity of hypertrophied astrocytic profiles, and were sometimes completely surrounded by astrocytic processes. The presynaptic(More)
Quantitative ultrastructural analysis of rat parietal cortex was undertaken to determine the nature of the synaptic changes occurring in the molecular layer over a series of ages in early- (3 months), mid- (6 and 10 months) and late- (17 months) adulthood. The total number of synapses remained constant until 10 months of age, but decreased significantly by(More)
Quantitative ultrastructural analyses of ethanolic phosphotungstic acid-stained human layer 1 precentral motor cortex (Brodmann's area 4) and layer 1 postcentral somatosensory cortex (Brodmann's area 3) were undertaken to determine the nature of synaptic changes occurring over a series of ages (45-84 years) of a normal aging human population. In the(More)
A review of one thousand injuries due to Rugby Football is reported. There is a high incidence of fracture (15.7%) and head injury of various types (14.0%) in this series although only four adults required immediate hospital admission for the head injury.
Streptococcus pyogenes rarely causes meningitis. A recent increase in the incidence and severity of diseases due to S. pyogenes has been observed worldwide, without an apparent increase in the incidence of S. pyogenes meningitis. However, more recently severe and fulminant cases of S. pyogenes meningitis have been reported in the literature. This case(More)
The tape-measure is frequently used by the medical profession to assess muscle function following injury. It is assumed that increasing limb girth is reflected by increasing muscle power and strength; but this assumption is empirical and may not in practice be justified. The relationship between thigh circumference and muscle strength and power, measured as(More)
Transforming growth factor-beta (TGF-beta), a multifunctional, immunosuppressive cytokine, is shown to be present in substantial amounts in commercially available intravenous immunoglobulin (IVIG) preparations. To assess whether TGF-beta isoforms are changed in the plasma of paediatric patients with childhood autoimmune diseases after IVIG infusion, 17(More)
