INTRODUCTION The aim of the study was to evaluate the incidence of chronic post-traumatic stress disorder (PTSD) after childbirth in relation to pre-partum variables (personality characteristics, anamnestic risk factors) and intra-partum obstetrical and neonatal variables. Since expectations before an event could modify the perceptions, reactions, and(More)
The ultrastructure of the luminal surface epithelium was compared in endometrial samples taken from 23 normally cycling women and from 22 patients submitted to ovarian stimulation with clomiphene citrate (100 mg/day for 5 days), human menopausal gonadotrophin (hMG) and human chorionic gonadotrophin (hCG). On day 2 after ovulation, only four out of nine(More)
OBJECTIVE To assess the adaptation in autonomic control mechanisms that accompanies the marked haemodynamic changes, such as increases in cardiac size and output, that occur in the course of normal human pregnancy. DESIGN We studied 14 healthy pregnant women (aged 30+/-1 years) before the 6th week (early stage) and within weeks 32-34 (late stage) of(More)
"Chronoastrobiology: are we at the threshold of a new science? Is there a critical mass for scientific research?" A simple photograph of the planet earth from outer space was one of the greatest contributions of space exploration. It drove home in a glance that human survival depends upon the wobbly dynamics in a thin and fragile skin of water and gas that(More)
This review provides evidence that the bioengineering community needs to develop cost-effective, fully unobtrusive, truly ambulatory instrumentation for the surveillance of blood pressure and heart rate. With available instrumentation, we document a disease risk syndrome, circadian blood pressure overswinging (CHAT, short for circadian(More)
Taking the heart rate (HR) for one cycle, whether to examine behavior in the region of periods of 1 s, 1 day, 1 week, 1.3 or 10.5 years, etc., is hazardous. Replications, when possible are mandatory for examining altered variability, whatever the period(s) involved may be. This replication in the individual, and across individuals when the periods are long,(More)
System time is defined as the duration (T) and sampling density (deltat) of a given study. A time horizon is obtained by combining analytical results on endpoints of time structures (chronomes), usually on control groups, from accumulating diverse studies carried out with drastically different values of T and deltat. These two design considerations depend(More)
