Menstrual cycle variation in women's preferences for the scent of symmetrical men.

Abstract: Evidence suggests that female sexual preferences change across the menstrual cycle. Women’s extra-pair copulations tend to occur in their most fertile period, whereas their intra-pair copulations tend to be more evenly spread out across the cycle.This pattern is consistent with women preferentially seeking men who evidence phenotypic markers of genetic bene¢ts just before and during ovulation.This study examined whether women’s olfactory preferences for men’s scent would tend to favour the scent of more symmetrical men, most notably during the women’s fertile period. College women sniied and rated the attractiveness of the scent of 41T-shirts worn over a period of two nights by diierent men. Results indicated that normally cycling (non-pill using) women near the peak fertility of their cycle tendedto prefer the scent of shirts worn by symmetrical men. Normally ovulating women at low fertility within their cycle, and women using a contraceptive pill, showed no signi¢cant preference for either symmetrical or asymmetrical men’s scent. A separate analysis revealed that, within the set of normally cycling women, individual women’s preference for symmetry correlated with their probability of conception, given the actuarial value associated with the day of the cycle they reported at the time they smelled the shirts. Potential sexual selection processes and proximate mechanisms accounting for these ¢ndings are discussed.

Identification of increased nitric oxide biosynthesis during pregnancy in rats.

Abstract: We reported previously that plasma levels, urinary excretion, and metabolic production of cyclic guanosine 3',5'-monophosphate (cGMP) are increased in gravid rats, and postulated that endogenous nitric oxide (NO), a potent vasodilator and immune modulator, may mediate this change. Four lines of evidence are now presented demonstrating increased biosynthesis of NO during pregnancy in rats: 1) Urinary excretion and plasma levels of the stable NO metabolite, nitrate, are elevated in pregnant rats; urinary excretion of nitrate is increased in pseudopregnant rats. 2) The urinary excretion of cGMP also increases during pregnancy and pseudopregnancy, paralleling the rise in urinary nitrate excretion. 3) Chronic treatment with the NO synthase inhibitor, NG-nitroarginine methyl ester (NAME), inhibits the increase in urinary nitrate excretion. 4) Nitric oxide hemoglobin is detected by electron paramagnetic resonance spectroscopy in the blood of pregnant, but not in nonpregnant, rats. The results show endogenous NO production is increased in gravid rats. This finding raises the possibility that NO may contribute to maternal vasodilation and uterine immune suppression of normal pregnancy.

Customer relationship management: key components for IT success

Abstract: This article is directed towards information technology (IT) and marketing managers considering implementation of a customer relationship management (CRM) solution. The goal of this article is not to provide an all‐inclusive tutorial on CRM, but rather to provide a high level insight of the fundamental principles behind CRM and critical aspects of the IT development process. The article begins with an IT manager’s introduction into the basic CRM business and marketing principles. At the heart of the article is a proposed system development lifecycle that highlights the aspects unique or critical to CRM. Finally, it concludes with some final thoughts for long‐term success. After reading this article, the reader will be mindful of the major issues needed for success and be equipped to discuss primary development matters with vendors, staff and management.

Adverse effects of early dexamethasone treatment in extremely-low-birth-weight infants

Abstract: Background Early administration of high doses of dexamethasone may reduce the risk of chronic lung disease in premature infants but can cause complications. Whether moderate doses would be as effective but safer is not known. Methods We randomly assigned 220 infants with a birth weight of 501 to 1000 g who were treated with mechanical ventilation within 12 hours after birth to receive dexamethasone or placebo with either routine ventilatory support or permissive hypercapnia. The dexamethasone was administered within 24 hours after birth at a dose of 0.15 mg per kilogram of body weight per day for three days, followed by a tapering of the dose over a period of seven days. The primary outcome was death or chronic lung disease at 36 weeks' postmenstrual age. Results The relative risk of death or chronic lung disease in the dexamethasone-treated infants, as compared with those who received placebo, was 0.9 (95 percent confidence interval, 0.8 to 1.1). Since the effect of dexamethasone treatment did not vary a...

Charge-Dipole Model for the Universal Field Dependence of Mobilities in Molecularly Doped Polymers

Abstract: Using the general result that the mobility $\ensuremath{\mu}$ of charge carriers driven in a spatially correlated random potential by an electric field $E$ can be expressed in terms of the Laplace transform of a particular correlation function related to the random potential, we demonstrate that the exponential dependence of $\ensuremath{\mu}$ on $\sqrt{E}$ universally observed in molecularly doped polymers arises naturally from the interaction of charge carriers with randomly distributed permanent dipoles.
