Twenty-one women undergoing termination of pregnancy for severe fetal abnormality received remifentanil and propofol using a target-controlled infusion system and were studied prospectively. Target concentrations were initially set at 1 ng.mL(-1) for remifentanil and 0.8 microg.mL(-1) for propofol. Remifentanil concentration was adjusted to obtain visual(More)
A study was made of the dynamics of psychophysiological parameters and the activities of the systems regulating the heart rate in prospective post-secondary students taking competitive entrance examinations. The responses of the regulatory systems to examination stress were of two types, sympathetic and parasympathetic, depending on the initial state of the(More)
Effects of examination stress on psychological characteristics and indices of the autonomic nervous system were studied in pupils of the eighth and tenth grades of high schools providing differential (test group, “Neuron” gymnasium) and general education (control group). General health state and levels of activity and mood (feeling, activity, mood; FAM) and(More)
The effects of daily and weekly academic loads on the psychological and cardio-and hemodynamic characteristics of students were analyzed. The self-estimated state of health, activity, and mood were evaluated with the use of the HAM (Health-Activity-Mood) questionnaire; the introversion and extraversion, neuroticism, and intelligence of the subjects were(More)
Obsessive-compulsive disorder (OCD) is an anxiety disorder characterized by repeated thoughts and behaviors. Inhibitory deficits are presumably related to the onset and maintenance of this disorder. The present study investigated whether obsessive-compulsive (OC) symptoms are related to enhanced response tendencies in reaction to external stimuli. Our goal(More)
Obsessive-compulsive disorder (OCD) is characterized by repeated thoughts and behaviors. This study explored the stages of motor response preparation that precede action performance or inhibition: We investigated whether OCD is related to enhanced action tendencies in response to external stimuli. Response preparation processes were assessed using the(More)
Over periods exceeding two years, 63 Pseudomonas aeruginosa strains isolated from three children with cystic fibrosis were characterized using a 154 character auxanogram. Numerical analysis was carried out to establish intrastrain variability in relation to intensity of immune response and clinical outcome. For two patients, strains segregated in two(More)
