A "hot patella" is a bone scan finding of increased tracer uptake in the patella, greater than the ipsilateral distal femur or the proximal tibia. Increased patellar uptake on the bone scans is a relatively frequent finding; this is often not commented upon. The aim of our study was to define the incidence of a "hot patella" on bone scans following total(More)
1. The changes in heart rate and arterial pressure produced by the intravenous injection of isoprenaline (0.5 mug/kg), noradrenaline (1.0 mug/kg), phenylethylamine (0.5 mg/kg), amphetamine (0.5 mg/kg) and by bilateral occlusion of the carotid arteries and by stimulation of the central ends of both vagus nerves have been recorded in groups of dogs(More)
Temporal detection thresholds are reported from two subjects to dynamic random dot stereograms (DRDSs) of both crossed and uncrossed disparity. The stimuli were 1 degree square, of 0.25 degrees disparity and were presented at 81 positions in a 9 degree square central region. In both subjects crossed disparity stimuli were detected at shorter durations. One(More)
Young (3-week-old) spontaneously hypertensive rats (SHR) had significantly higher basal plasma corticosterone levels than WKY rats and maximum responses to ACTH were also higher. In isolated adrenocortical cells from these rats, corticosterone production was also more responsive to ACTH in SHR. There was no significant difference in aldosterone production.(More)
The diagnosis of prosthetic joint infection and its differentiation from aseptic loosening remains problematic. The definitive laboratory diagnostic test is the recovery of identical infectious agents from multiple intraoperative tissue samples; however, interpretation of positive cultures is often complex as infection is frequently associated with low(More)
BACKGROUND & PURPOSE Skeletal stem cells (SSCs) and impaction bone grafting (IBG) can be combined to produce a mechanically stable living bone composite. This novel strategy has been translated to the treatment of avascular necrosis of the femoral head. Surgical technique, clinical follow-up and retrieval analysis data of this translational case series is(More)
