BACKGROUND After acute myocardial infarction (AMI), several abnormalities of the autonomic control to the heart have been described. Heart rate (HR) variability has been used to explore the neural control to the heart. A low HR variability count measured 7-13 days after AMI is significantly related to a poor outcome. Little information is available on HR(More)
PURPOSE OF THE STUDY We aimed to evaluate whether prolonged occlusion can induce stratum corneum barrier damage, alterations in stratum corneum hydration or water-holding capacity (WHC) lasting longer than the occlusion time. MATERIALS AND METHODS 12 subjects were occluded on the forearm for 24, 48, 72 and 96 h. Two hours after occlusion removal,(More)
BACKGROUND Non-invasive bioengineering methods are widely used in the assessment of irritant skin reactions. OBJECTIVES To assess the ability of eight non-invasive measurement techniques to distinguish changes in skin conditions over time, these changes being induced by five different irritants. METHODS The following techniques were compared in a(More)
BACKGROUND Inferential evidence suggests that silent ischemia might be related to sympathetic activity. Study of [3H]norepinephrine kinetics is a suitable tool to assess the regional sympathetic activity. This method was applied to investigate whether silent myocardial ischemia in unstable angina is related to and depends on cardiac sympathetic(More)
Two studies were performed to evaluate the influence of glycerol on the recovery of damaged stratum corneum barrier function. Measurements of transepidermal water loss and capacitance were conducted in a 3-day follow-up after tape stripping (study 1) and a 7-day follow-up after a barrier damage due to a repeated washing with sodium lauryl sulphate. In study(More)
The differences between pre- and postmenopausal women and men on corneocyte surface area were investigated by a noninvasive exfoliation method. Surface corneocytes were collected with a modified detergent scrub technique. Separated corneocytes were analyzed by videomicroscopy and image analyses (NIH Image 1.59). Additionally transepidermal water loss (TEWL)(More)
BACKGROUND Heart Rate (HR) and Heart Rate Variability (HRV) depend on the neural control to the heart. HRV can be measured from 24-hours function. Little information is available on cardiac rhythm and on autonomic nervous control to the heart at birth. The aims of the study weew: 1) to study the cardiac rhythm in healthy newborn babies; 2) to asses the(More)
This study was designed to assess the accuracy of a diagnostic protocol of the mobile coronary care unit (MCCU) of Florence for acute chest discomfort. During 1986, 706 patients with chest pain were seen by the MCCU. Of these, 324 of 376 (95.2%) of those hospitalized and 247 of 324 (76.2%) of the nonhospitalized patients were entered in the study. The MCCU(More)
