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)
"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)
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)
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)
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)
BACKGROUND A high incidence of erectile dysfunction (ED) among patients with obstructive sleep apnoea syndrome (OSAS) has been reported, with a strong correlation between obstructive sleep apnoea, ED, and quality of life (QOL), and it has been estimated that 10-60% of patients with OSAS suffer from ED. In this prospective randomised controlled trial, we(More)
Geomagnetic activity has a strong half-yearly but no precise yearly component in its spectrum, as Armin Grafe suggested nearly half a century ago. We have postulated elsewhere that non-photic cycles such as those in geomagnetics may have signatures in the biosphere and vice versa that biological rhythms have likely counterparts in the physical environment.(More)
