Background We investigated the relationship between receptivity to electronic cigarette (e-cigarette) advertisements at baseline and e-cigarette use at follow-up among adult baseline non-users of cigarettes and e-cigarettes. Methods A nationally representative online panel was used to survey non-users of cigarettes and e-cigarettes (n = 2191) at baseline and 5-month follow-up. At baseline, re...

Most models of sexual selection focus on coevolution of male sexual trait and female preference for the trait. However, whether the female preference modifies the male trait depends on the overall receptivity of females, on the importance of the male trait for the females, on female sampling behaviour, and on female control over copulation decision. These aspects are often neglected by theoreti...

Neuroendocrine mechanisms underlying complementary behaviors like male-typical mounting and female-typical receptivity are most often studied independently in males and females, respectively. Cnemidophorus uniparens is a unisexual lizard species consisting only of females that alternately express male- and female-like pseudosexual behavior across the ovarian cycle. Intact, postovulatory (PostOv...

Previous studies have investigated the lower embryo implantation rates in women with polycystic ovary syndrome, obesity and type 2 diabetes, and specifically the association between the abnormal oocyte and embryo and hyperinsulinemia. The importance of hyperinsulinemia on maternal endometrium receptivity remains to be elucidated. The present study used a hyperinsulinemic mouse model to determin...

The endometrium is a hormonally regulated organ that is non-adhesive to embryos throughout most of the menstrual cycle in humans. Endometrial receptivity refers to a hormone-limited period in which the endometrial tissue acquires a functional and transient ovarian steroid-dependent status allowing blastocyst adhesion. Functional genomic studies of human endometrium in natural cycles have demons...

However, the notion of receptivity as a static state in which the tissue is poised, frozen in time, awaiting the arrival of an adequately developed embryo, is naïve. An integrative definition of receptivity must embrace communication between maternal and embryonic tissues. At receptivity, the endometrium has reached a point at which negotiation can begin that may or may not lead to successful i...

the success rate of several advanced basic and clinical techniques in the field of mammalian biotechnology, including cloning, pre-implantation genetic diagnosis, and assisted reproductive techniques (art) depends mainly on the success rate of pregnancy following in vitro fertilization-embryo transfer (ivfet). the techniques used in art have advanced considerably since the first in vitro fertil...

Drawing on the notions of subjective knowledge (what someone thinks he/she knows about a topic) and receptivity (someone's ability, inclination, willingness to take in information, ideas, impressions or suggestions), we extend knowledge-attitudes-practice (KAP) model within an environmental sustainability policy (ESP) context: UK's single-use bag charge policy, specifically. Based cross-section...
