Despite the accumulating evidence suggesting that the neuropeptide oxytocin (OT) plays a role in neuropsychiatric disorders characterized by social dysfunction, the influence of OT on the nonsocial aspects of learning and memory have been less investigated. To foster research in this area, we review the effects of OT on learning and memory in animal models and humans. In healthy animal models, ...

We investigated the production of oxytocin (OT) and oxytocin-neurophysin (bNpI) by bovine granulosa cells cultured in presence of 10% foetal calf serum, a condition known to induce spontaneous luteinization of these cells. The production of immunoreactive OT was significantly higher in the cultures of granulosa cells harvested from large follicles than in those derived from small follicles. Chr...

The title compound, C(18)H(15)BrSi, crystallizes with two almost identical mol-ecules (r.m.s. deviation for all non-H atoms = 0.074 Å) in the asymmetric unit. It is isomorphous with chloro-triphenyl-silane.

The right ventricular outflow tract (OT) is a functionally distinct area of the right ventricle. However, there is little information on the contrdingly, inflow tract (IT) and OT chords and right ventricular free wall segmental changes were measured with implanted ultrasound crystals. The timing and extent of shortening of IT and OT chords and free wall segments were determined both at rest and...

An oblivious transfer (OT) protocol allows a receiver to obtain one of two bits held by a sender without revealing its selection. An OT combiner securely implements OT by using oracle access to n OT candidates of which at most t may be insecure. It is known that OT combiners exist when t < n/2. However, known constructions either invoke each candidate multiple times or alternatively require t t...

Previous studies have suggested that administration of oxytocin (OT) can have modulatory effects on social and anxiety-like behavior in mammals that may endure beyond the time of acute OT administration. The current study examined whether repeated administration of OT to male Wistar rats (n = 48) during a key developmental epoch (early adolescence) altered their physiology and behavior in later...

Behavioral neuroscientists have shown that the neuropeptide oxytocin (OT) plays a key role in social attachment and affiliation in nonhuman mammals. Inspired by this initial research, many social scientists proceeded to examine the associations of OT with trust in humans over the past decade. To conduct this work, they have (a) examined the effects of exogenous OT increase caused by intranasal ...

OBJECTIVE Oxytocin (OT) has been implicated to play an important role in autism spectrum disorders (ASD) etiology. We aimed to find out the differences in plasma OT levels between children with autism and healthy children, the associations of OT levels with particular autism symptoms and the associations of particular parental autistic traits with their ASD children OT levels. METHODS We incl...

Results from previous studies indicate that oxytocin (OT)-containing neural pathways are activated in laboratory rats after systemic administration of CCK or d-fenfluramine and that centrally released OT may participate in the anorexigenic effects of these treatments. To explore the relationship between feeding behavior and OT function, the effects of CCK and d-fenfluramine on feeding and centr...
