Oxytocin (OT) has been linked to social behavior in rodents, non-human primates, and adult humans, but almost nothing is known about brain OT activity in human newborns or its impact on social development. To better understand the role of OT biology in human social functioning, a multi-disciplinary, longitudinal study was conducted. Cerebral spinal fluid (CSF) OT levels from 18 human neonates w...
We report that oxytocin (OT), a primitive neurohypophyseal hormone, hitherto thought solely to modulate lactation and social bonding, is a direct regulator of bone mass. Deletion of OT or the OT receptor (Oxtr) in male or female mice causes osteoporosis resulting from reduced bone formation. Consistent with low bone formation, OT stimulates the differentiation of osteoblasts to a mineralizing p...
1 Parr, L. A., Modi, M., Siebert, E., & Young, L. J. (2013). Intranasal oxytocin selectively attenuates rhesus monkeys' attention to negative facial expressions. Psychoneuroendocrinology, 38, 1748-1756. Notes: Intranasal oxytocin (IN-OT) modulates social perception and cognition in humans and could be an effective pharmacotherapy for treating social impairments associated with neuropsychiatric ...
improvement of artificial insemination efficiency in zandi ewes via estradiol and oxytocin injection
the aim followed in the present study was to evaluate the effect of estradiol (e2) injection and injection (either intramuscular (i.m) or intravenous (i.v)) of various doses of oxytocin (ot) on cervix dilation and on conception rate in zandi ewes during late breeding season. sixty three ewes were randomly selected. in experiment 1, the ewes received 100 µl e2 and 12h later were divided and assi...
Developmental exposure to oxytocin (OT) or oxytocin antagonists (OTAs) has been shown to cause long-lasting and often sexually dimorphic effects on social behaviors in prairie voles (Microtus ochrogaster). Because regulation of social behavior in monogamous mammals involves central receptors for OT, arginine vasopressin (AVP), and dopamine, we examined the hypothesis that the long-lasting, deve...
Previous studies have suggested that oxytocin (OT) may be anxiolytic in female laboratory rats and mice. The elevated plus-maze was used to compare anxiety-related behaviors of OT-deficient (OT-/-) and wild-type (OT+/+) mice. Female OT-/- mice displayed increased anxiety-related behavior compared with OT+/+ mice. The percentage of entries (P < 0.0002) and time spent (P < 0.003) in the open arms...
In previous studies we found indications of stress reduction in saline-injected rats when exposed to an oxytocin (OT)-injected cage mate. Olfactory impairment and OT antagonist treatment abolished the effects. This suggested an olfactorily mediated oxytocinergic stress-inhibitory mechanism. To test this hypothesis bodyweight, tail skin temperatures, food-intake and plasma ACTH and corticosteron...
In recent decades, scientific understanding of the many roles of oxytocin (OT) in social behavior has advanced tremendously. The focus of this research has been on maternal attachments and reproductive pair-bonds, and much less is known about the substrates of sociality outside of reproductive contexts. It is now apparent that OT influences many aspects of social behavior including recognition,...
This article is a biopsychosocial proposal about improvement of resilience to diseases, including the COVID-19, due affective attachment between humans and dogs. Resilience concerns physical emotional human capacity respond positively adverse events such as diseases. Recently, some authors have proposed independent hypotheses role oxytocin (OT) crossed immunity increase psychological immune res...
The effects of Equex STM paste (Equex) and oxytocin (OT) on the in vitro quality of frozen-thawed Asian elephant sperm were investigated in the study. The viability of frozen-thawed sperm was significantly higher in the Equex-treated (1 and 2%) groups than in the control group. There were no differences in the examined sperm parameters among the control and OT-treated (0.05-5IU) groups.
