The purpose of this study was to examine whether mental fatigue influences the perceived effort required to complete fairly light and hard effort self-paced exercise challenges. 12 participants completed 2 trials in a randomised cross-over design. Each participant was required to complete a time-matched pre-exercise task: 1) a continuous cognitive activity(More)
Variations of plasma LH and testosterone in relation to sleep-related penile tumescence were assessed. Plasma LH and testosterone were measured at 10-20 min intervals in five normal adult men during 2 nights of sleep. Blood samples were obtained by means of an indwelling venous catheter while sleep was monitored polygraphically and penile tumescence(More)
Nocturnal penile tumescence (NPT) was assessed in 30 impotent patients for the purpose of differential diagnosis. In 11 psychogenic cases, with several exceptions, NPT was found to be normal, with a marked discrepancy between the NPT findings and the patients' estimates of their daytime erectile capacity. In 19 organic patients, maximal NPT corresponded(More)
INTRODUCTION Based on clinical observations, we hypothesized that in infiltrative high-grade brainstem neoplasms, such as diffuse intrinsic pontine glioma (DIPG), longitudinal metabolic evaluation of the tumor by magnetic resonance spectroscopy (MRS) may be more accurate than volumetric data for monitoring the tumor's biological evolution during standard(More)
BACKGROUND AND PURPOSE The conventional MR imaging appearance of diffuse intrinsic pontine glioma suggests intralesional histopathologic heterogeneity, and various distinct lesion components, including T2-hypointense foci, have been described. Here we report the prevalence, conventional MR imaging semiology, and advanced MR imaging features of non-necrotic(More)
BACKGROUND AND PURPOSE Assessing the response to treatment in infiltrative brain tumors by using lesion volume-based response criteria is challenging. We hypothesized that in such tumors, volume measurements alone may not accurately capture changes in actual tumor burden during treatment. We longitudinally evaluated volume changes in both normal-appearing(More)
Eighty patients who had undergone routine meniscectomy were divided into two groups for postoperative management. The first 40 patients were treated by the traditional method of a compression bandage with a backsplint, followed by a 10-day stay in hospital. In the other 40 patients a compression bandage was applied, reinforced by a plaster cylinder.(More)
