Little attention has been directed toward identifying the changes which occur in salivary composition in response to exercise. To address this, our article first refers to the main aspects of salivary gland physiology. A knowledge of the neural control of salivary secretion is especially important for the understanding of the effects of exertion on salivary(More)
Peak oxygen consumption (peak VO2) has become a critical component in the evaluation of heart transplant recipients (HTR). In these patients, peak VO2 remains low after cardiac transplantation mainly because of persisting peripheral limitations in the working muscles. Muscular electrical stimulation, on the other hand, has been shown to enhance the(More)
A family with familial cerebellar ataxia and hypogonadotropic hypogonadism is described. The condition was inherited as an autosomal recessive defect. CT scan in one case revealed cerebellar and brain stem atrophy. Endocrinological tests showed abnormalities only in two patients who were clinically affected. In both cases raised gonadotropic levels were(More)
INTRODUCTION The medical conditions shared by hospital emergency services and community-hospital neurology clinics (CHNC) have not been described, and the quality of the medical care received in these conditions has not been evaluated in our environment. METHODS Over a 2 month period, those patients presenting at any of the seven CHNC in a Health Care(More)
The purpose of this study was to determine the anaerobic threshold from analysis of amylase concentration in total saliva during a laboratory exercise test. Each of 20 healthy young men performed both a submaximal and a maximal test on a treadmill. During the submaximal test, capillary blood and total saliva samples were collected for determination of(More)
UNLABELLED To establish the frequency of drug-induced parkinsonism (DIP) and the drugs responsible for this side-effect we reviewed the database of our Movement Disorders Unit during the first 4 years of its use. The diagnostic criteria for DIP included: (1) the presence of two or more cardinal symptoms of parkinsonism, (2) an absence of parkinsonian(More)
BACKGROUND The purpose of our investigation was to assess the use of a fixed value (12-13) of the Rating of Perceived Exertion (RPE) scale (6-20) as a valid method for the determination of the workload corresponding to the ventilatory threshold (VT) during a ramp protocol on a cycle ergometer. METHODS Eleven trained cyclists (22 +/- 3 years of age;(More)
BACKGROUND Previous studies have shown the diagnostic relevance of the so-called free testosterone/cortisol ratio (FTCR). A condition of overtraining might indeed exist in an athlete when at least one of the two following criteria are observed: a) a FTCR value lower than 0.00035 (FT in nmol x L(-1) and C in micromol x L(-1)); and b) a decrease in the FTCR(More)
