The effects of transcutaneous electrical stimulation on left visuo-spatial hemineglect, assessed by a visuo-motor exploratory task (letter cancellation), were investigated in patients with right hemisphere lesions. In Experiment 1 left neck stimulation temporarily improved the deficit in 13 out of 14 patients (93%), while stimulation of the right neck had(More)
The effects of transcutaneous electrical stimulation on deficits of tactile perception contralateral to a hemispheric lesion were investigated in 10 right brain-damaged patients and in four left brain-damaged patients. The somatosensory deficit recovered, transiently and in part, after stimulation of the side of the neck contralateral to the side of the(More)
OBJECTIVE To assess the occurrence, type, and burden of adverse clinical events (ACE) among residents of chronic facilities. An ACE is any acute or subacute change in health status suggesting acute or subacute illness. DESIGN Survey with face-to-face functional assessment and 3-month retrospective chart review. STUDY POPULATION One hundred six(More)
Space constancy was investigated in seven blindfolded left-neglect patients by driving them along routes involving one or two, left or right, 90 degrees turns. At the end of each route patients had to indicate its starting point while still blindfolded. On average, no considerable left/right differences were found in pointing accuracy. The entailments of(More)
In epidemiological studies, a high haematocrit has been associated both with increased cardiovascular risk and with hyperinsulinaemia, a surrogate of insulin resistance. To examine directly the relationship between the haematocrit and insulin sensitivity, we studied 12 healthy volunteers and 12 patients with non-insulin-dependent diabetes mellitus (NIDDM)(More)
Both hyperinsulinemia and free oxygen radicals have been implicated in the pathogenesis of atherosclerosis, but the relationship between insulin levels or insulin action and the oxidant/antioxidant balance has not been explored. We measured the effect of physiologic hyperinsulinemia on plasma concentrations of vitamin E, a major free radical scavenger(More)
To evaluate the metabolic or cardiovascular effects induced by self-administration of human growth hormone (HGH) alone or combined with testosterone and anabolic steroids, we conducted a study with 15 male body builders. Of these, 8 (control group) did not take any hormonal substances; 6 (experimental group) self-administered testosterone, anabolic(More)
BACKGROUND In vitro sunscreen tests are diffusively used to test both the sun protection factor (SPF) and the photo-stability of filters. Spectrophotometric measurements of the absorbance of ultraviolet radiations through a sunscreen applied on a suitable substrate allow a rapid evaluation of its protection factor both at short and long wavelength(More)
