Are postural responses to backward and forward perturbations processed by different neural circuits?
Item does not contain fulltext Startle pathways may contribute to rapid accomplishment of postural stability. Here we investigate the possible influence of a startling auditory stimulus (SAS) on postural responses. We formulated four specific questions: (1) can a concurrent SAS shorten the onset of automatic postural responses?; and if so (2) is this effect different for forward versus backward perturbations?; (3) does this effect depend on prior knowledge of the perturbation direction?; and (4) is this effect different for low- and high-magnitude perturbations? Balance was perturbed in 11 healthy participants by a movable platform that suddenly translated forward or backward. Each particip…
Intravesical bleomycin in bladder tumour prophylaxis.
The authors have evaluated the efficacy, tolerability and systemic absorption of bleomycin administered by intravesical route in the prophylaxis of recurrences of superficial vesical tumours after endoscopic resection (TUR). Thirty mg of bleomycin dissolved in 30 ml of saline solution were instilled in the bladder once a week for the first month and then once a month for 12 months. The instilled fluid was held in the bladder for 1 hour. The systemic absorption of the drug was evaluated by a microbiological assay of bleomycin in plasma and in the perfusion liquid recovered from the bladder. Fifteen patients were treated; most had a long history of multiple recurrent tumours despite previous …
