Oxytocin Receptor Signaling in Vascular Function and Stroke

Frontiers in Neuroscience, 2020
The oxytocin receptor (OXTR) is a G protein-coupled receptor with a diverse repertoire of intracellular signaling pathways, which are activated in response to binding oxytocin (OXT) and a similar nonapeptide, vasopressin.

Oxytocin and orexin systems bidirectionally regulate the ability of opioid cues to bias reward seeking

Translational Psychiatry, 2022
As opioid-related fatalities continue to rise, the need for novel opioid use disorder (OUD) treatments could not be more urgent. Two separate hypothalamic neuropeptide systems have shown promise in preclinical OUD models. The oxytocin system, originating

A role of the uterine cervix in the pathogenesis of adenomyosis and endometriosis?

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Data indicate a link between the cervix and pathologies like adenomyosis and endometriosis. Uterine flexion on the cervix, diameter and stiffness of the internal cervical orifice represent an obstacle to downstream menstrual flow, that when excessive increases the intensity of uterine contractions.

New Topics in Vasopressin Receptors and Approach to Novel Drugs: Vasopressin and Pain Perception

Journal of Pharmacological Sciences, 2009
Arginine vasopressin (AVP) activates three vasopressin receptors and it also has an agonistic activity on the oxytocin receptor. For an accurate description of the target receptor subtype(s) responsible for complex AVP and oxytocin actions, a careful ...

Differential effects of MDMA and methylphenidate on social cognition [PDF]

, 2014
Social cognition is important in everyday-life social interactions. The social cognitive effects of 3,4-methylenedioxymethamphetamine (MDMA, 'ecstasy') and methylphenidate (both used for neuroenhancement and as party drugs) are largely unknown.

Prostaglandin dose and time to fetal expulsion after intrauterine fetal death at 22 to 28 gestational weeks in Sweden: A retrospective cohort study

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective Prostaglandin regimens for induction of intrauterine fetal death (IUFD) <28 gestational weeks (GW) are unstandardized. We aimed to describe prostaglandin regimens for induction after IUFD and assess association between dose and time to fetal expulsion.

The anterior cervical angle: A novel predictor of vaginal birth

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective This study investigates the role of anterior utero‐cervical angle as a predictor of labor induction success, comparing outcomes between normal vaginal delivery and cesarean section groups. Methods A prospective cohort study was conducted on 55 patients undergoing labor induction (46 normal vaginal delivery, 9 cesarean section ...

Chronic oxytocin administration stimulates the oxytocinergic system in children with autism

Nature Communications
Clinical efficacy of intranasal administration of oxytocin is increasingly explored in autism spectrum disorder, but to date, the biological effects of chronic administration regimes on endogenous oxytocinergic function are largely unknown.

Development of Magnetic Nanobeads Modified by Artificial Fluorescent Peptides for the Highly Sensitive and Selective Analysis of Oxytocin

Sensors, 2020
We describe two novel fluorescent peptides (compounds 1 and 2) targeting oxytocin with a boron-dipyrromethenyl group as the fluorophore bound to an artificial peptide based on the oxytocin receptor, and their application for the analysis of oxytocin ...
