This study compared the effects of centrally administered oxytocin (OT) and arginine vasopressin (AVP) on partner preference formation and social contact in male and female prairie voles (Microtus ochrogaster). After 1 hr of cohabitation and pretreatment with either AVP or OT, both males and females exhibited increased social contact and significant preference for the familiar partner. After pr...

An efficient scheme is proposed which achieves the oblivious transfer with probabilistic receipt, α-OT, approximately for 0 < α < 1. The proposed scheme approximates α-OT with 2−i-OT for i = 1, 2, . . . , k. It implements γ-OT for some γ such that (α − 2−k)/(1 − 2−k) < γ ≤ α with − log(1 − α) invocations of 2−1-OT and at most 2 invocations of 2−i-OT for each i = 2, . . . , k. These invocations ...

We present a recently proposed theory of grammar, Optimality Theory (OT; Prince & Smolensky 1991, 1993). The principles of OT derive in large part from the high-level principles governing computation in connectionist networks. The talk proceeds as follows: (1) we summarize OT and its applications to UG. The we present (2) learning and (3) parsing algorithms for OT. Finally, (4) we show how cruc...

Oxytocin (OT), a nanopeptide hormone, plays a role in the emergence of maternal behavior, yet few studies examined OT in humans across pregnancy and the postpartum. We followed healthy women at three points: first trimester of pregnancy, third trimester, and first postpartum month. Plasma OT levels showed high individual stability. A third of the sample showed consistent OT levels, whereas othe...

Background: Oxytocin (OT) is a paracrine hormone with various biological activities and many sex organs in both sexes, as well as many tumor cells have shown to have related receptors. In this study the development of a receptor imaging tracer for possible tumor imaging has been described. Materials and Methods: OT was successively labeled with [67Ga]-gallium chloride after conjugation with fre...

Central oxytocin (OT) neurons limit intracerebroventricular (icv) ANG II-induced NaCl intake. Because mineralocorticoids synergistically increase ANG II-induced NaCl intake, we hypothesized that mineralocorticoids may attenuate ANG II-induced activation of inhibitory OT neurons. To test this hypothesis, we determined the effect of deoxycorticosterone (DOCA; 2 mg/day) on icv ANG II-induced c-Fos...

An OT-combiner takes n candidate implementations of the oblivious transfer (OT) functionality, some of which may be faulty, and produces a secure instance of oblivious transfer as long as a large enough number of the candidates are secure. We see an OT-combiner as a 2-party protocol that can make several black-box calls to each of the n OT candidates, and we want to protect against an adversary...

The difficulty of cervical penetration severely limits the use of transcervical AI (TAI) in sheep, and trauma from cervical manipulation (CM) may reduce fertility after TAI. We investigated the effects of cervical dilation using exogenous oxytocin (OT) to facilitate TAI and its effects on reproductive variables after laparoscopic AI (LAI). Estrus was synchronized by inserting pessaries impregna...

Previous studies showed the protective effects of oxytocin (OT) on myocardial injury in ischemic and reperfused rat heart. Moreover, exposure to various stressors not only evokes sudden cardiovascular effects but also triggers the release of OT in the rat. The present study was aimed to evaluate the possible cardioprotective effects of endogenous OT released in response to stress (St), and effe...
