What factors affect intrapartum maternal temperature? A prospective cohort study: maternal intrapartum temperature.
BACKGROUND In recent years, several reports have indicated that maternal temperature elevations during labor may also be observed in the absence of an infection. Presumed noninfectious causes of maternal temperature elevations include epidural analgesia, endogenous heat production generated by the contracting uterus, and delivery in an overheated room. To investigate the potential causes of non...
متن کاملIncrease in scrotal temperature in car drivers.
Several recent studies have reported a gradual decline in sperm production in men. Endocrine disrupters as well as lifestyle have been suggested as risk factors. One lifestyle factor that may affect human fertility is driving a vehicle for a prolonged period. Several authors have suggested that driving position may increase the scrotal temperature. In order to validate this hypothesis we conduc...
متن کاملTemperature increase of 21st century mitigation scenarios.
Estimates of 21st Century global-mean surface temperature increase have generally been based on scenarios that do not include climate policies. Newly developed multigas mitigation scenarios, based on a wide range of modeling approaches and socioeconomic assumptions, now allow the assessment of possible impacts of climate policies on projected warming ranges. This article assesses the atmospheri...
متن کاملMeasurement of sickling by controlled temperature increase.
Previous experiments to study the rate of red cell sickling have employed rapid mixing apparatus for SS cells with dithionite and have shown that the half-time of sickling is quite rapid, on the order of seconds. An alternative approach is to slow down the rate by taking advantage of the negative temperature coefficient of the process. We developed a method in which deoxygenation of a cell susp...
متن کاملTemperature-induced maternal effects and environmental predictability.
Maternal effects could influence the persistence of species under environmental change, but the adaptive significance of many empirically estimated maternal effects remains unclear. Inferences about the adaptive significance of maternal effects depend on the correlation between maternal and offspring environments, the relative importance of frequency- or density-dependent selection and whether ...
