Oxygen isotope analysis of benthic foraminifera in deep sea cores from the Atlantic and Southern Oceans shows that during the last interglacial period, North Atlantic Deep Water (NADW) was 0.4 degrees +/- 0.2 degrees C warmer than today, whereas Antarctic Bottom Water temperatures were unchanged. Model simulations show that this distribution of deep water temperatures can be explained as a resp...

[1] More than a decade ago, ice core records from Greenland revealed that the last glacial period was characterized by abrupt climate changes that recurred on millennial time scales. Since their discovery, there has been a large effort to determine whether these climate events were a global phenomenon or were just confined to the North Atlantic region and also to reveal the mechanisms that were...

OBJECTIVES This study aimed to determine the frequency of dysmenorrhea, as identified by different definitions, in a population of young women, and to investigate factors associated with this complaint. MATERIALS AND METHODS A final group of 408 young women completed a self-assessment questionnaire. This was a cross-sectional analytical study. RESULTS Menstrual pain was reported by 84.1% of...

Numerous studies have shown that menstrual cycle related variations in sex hormones influence various cognitive processes. These shifts are considered as the evidence for a hormone-mediated adaptive design underlying human mating motivation. In a series of related studies we have shown that (i) femininity does not vary across the menstrual cycle, whereas masculinity is the most pronounced durin...

Ultrasonic appearance probably indicative of imminent fetal death One of the difficulties in recognising fetal death by ultrasonic scanning in early pregnancy is that the negative finding of no fetal heart movement must always be less convincing than a positive finding. Furthermore, Robinson' found only one instance of irregularity of the fetal heart in ten cases scanned before their pregnancie...

Introdução: A "pobreza menstrual" é uma realidade invisível e injustiça social que impõe às mulheres penalidades relacionadas a tabus, estigmas, vergonha discriminação, além de reduzir o acesso tratamentos ginecológicos para sangramentos anormais, dismenorreia, infecções síndrome pré-menstrual. Objetivo: Realizar revisão sistemática identificar as populações vulneráveis à condição menstrual". F...
