The oxytocin receptor, luteolysis and the maintenance of pregnancy.

Journal of reproduction and fertility. Supplement, 2019
During luteal regression episodic pulses of oxytocin secretion become coupled to the release of prostaglandin F2 alpha (PGF2 alpha) following synthesis of endometrial oxytocin receptors, but in early pregnancy the inhibition of oxytocin receptor ...

Reconstruction of the Hypothalamo-Neurohypophysial System and Functional Dissection of Magnocellular Oxytocin Neurons in the Brain

Neuron, 2020
The hypothalamo-neurohypophysial system (HNS), comprising hypothalamic magnocellular neuroendocrine cells (MNCs) and the neurohypophysis, plays a pivotal role in regulating reproduction and fluid homeostasis by releasing oxytocin and vasopressin into the

Oxytocin at physiological concentrations evokes adrenocorticotropin (ACTH) release from corticotrophs by increasing intracellular free calcium mobilized mainly from intracellular stores. Oxytocin displays synergistic or additive effects on ACTH-releasing factor or arginine vasopressin-induced ACTH secretion, respectively [PDF]

, 1992
The potency of oxytocin (OT) in evoking ACTH secretion by isolated, superfused rat adenohypophyseal corticotrophs and its enhancement by CRF and arginine vasopressin (AVP) were analyzed.

Virtual reality simulation training for childbirth: A cluster randomized crossover study

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective To compare knowledge acquisition and domain‐specific feedback between virtual reality (VR) and mannequin‐based simulation for teaching medical students normal vaginal delivery (NVD). Methods We conducted a cluster randomized crossover study comparing a novel in‐house‐developed NVD VR simulator utilizing an Oculus® Quest 2 HMD with ...

Safety, Tolerability and Pharmacokinetics of Single Doses of Oxytocin Administered via an Inhaled Route in Healthy Females: Randomized, Single-blind, Phase 1 Study

EBioMedicine, 2017
Background: The utility of intramuscular (IM) oxytocin for the prevention of postpartum hemorrhage in resource-poor settings is limited by the requirement for temperature-controlled storage and skilled staff to administer the injection.

Brain-based health visiting: How neuroscience is shaping practice [PDF]

, 2014
Health visitors have always been faced with change and challenge to their role, partly as a result of health visiting being underpinned by a set of 'soft' skills that are difficult to articulate.

Chronic oxytocin administration as a treatment against impaired leptin signaling or leptin resistance in obesity

Frontiers in Endocrinology, 2015
This review summarizes the existing literature on the effects of oxytocin administration in the treatment of obesity in different animal models and in humans, focusing on the central control of food intake, the oxytocin effects on adipose tissue and the ...

Oxytocin and Self-Consciousness [PDF]

Frontiers in Human Neuroscience, 2016
In recent years, the study of self-consciousness from neuroscience and psychobiological perspectives has flourished rapidly. The understanding of the brain areas involved in self-consciousness and the complex intertwining of self-consciousness levels has expanded greatly, and the awareness of neurotransmitter influence on self-consciousness has begun ...

RAGE regulates oxytocin transport into the brain

Communications Biology, 2020
Oxytocin, a nonapeptide hormone, has a key role in female reproductive functions as well as in social memory in the brain. In our recent Communications Biology article, we reported that oxytocin is transported from the peripheral blood into the brain by ...

The involvement of actin, calcium channels and exocytosis proteins in somato-dendritic oxytocin and vasopressin release [PDF]

, 2012
Hypothalamic magnocellular neurons release vasopressin and oxytocin not only from their axon terminals into the blood, but also from their somata and dendrites into the extracellular space of the brain, and this can be regulated independently ...
