postconditioning is a simple and safe strategy for cardioprotection and infarct size limitation. our previous study showed that oxytocin (ot) exerts postconditioning effect on ischemic/reperfused isolated rat heart. the aim of this study was to investigate the involvement of ot receptor, mitochondrial atp-sensitive potassium channel (mkatp), nitric oxide (no) and cyclooxygenase (cox) pathways i...

Background: The capability of embryonic carcinoma cells P19 in differentiation to Cardiomyocyte was examined through inducing effects of Oxytocin (OT) and 5-Azacytidin (5Az) individually and compared with each other in laboratory condition. Materials and Methods: P19 Embryoid Bodies (EBs) was formed through hanging drops method. Then, EBs were treated with (5Az) or (OT) and the EB medium (Ct...

introduction: cardiac preconditioning represents the most potent and consistently reproducible method of rescuing heart tissue from undergoing irreversible ischemic damage. the aim of the present study was to evaluate oxytocin (ot) induced cardioprotection and its signaling pathways on lactate dehydrogenase (ldh) and creatine kinase-mb isoenzyme (ck-mb) in the anesthetized rats. methods: eighty...

Abstract Introduction: Occurrence of cardiac arrhythmias and myocardial infarction are two main deleterious events that are caused by ischemia-reperfusion (IR) injury in the heart. Cardiac preconditioning represents the most potent method of rescuing heart tissue from undergoing irreversible ischemic damage. The aim of the present study was to evaluate oxytocin (OT) cardioprotective effect...

Postconditioning is a simple and safe strategy for cardioprotection and infarct size limitation. Our previous study showed that oxytocin (OT) exerts postconditioning effect on ischemic/reperfused isolated rat heart. The aim of this study was to investigate the involvement of OT receptor, mitochondrial ATP-sensitive potassium channel (mKATP), nitric oxide (NO) and cyclooxygenase (COX) pathways i...

Oxytocin (OT) is a neuroendocrine nonapeptide that plays an important role in social memory and behavior. Nasal administration of OT has been shown to improve trust in healthy humans and social interaction in autistic subjects in some clinical trials. As a central nervous system (CNS) drug, however, OT has two unfavorable characteristics: OT is short-acting and shows poor permeability across th...

The nonapeptide oxytocin (OT) is used in medicine to help begin and/or continue childbirth. Its analogs can be also used to control bleeding following fetus delivery. The main function of oxytocin is to stimulate contraction of uterus smooth muscle and the smooth muscle of mammary glands, thus regulating lactation. This paper describes theoretical simulations of the distribution of the torsiona...

Cerebrospinal fluid and plasmatic levels of oxytocin (OT) have been found to change in mood disorders. In post-mortem studies, the numbers of OT-expressing neurons in the paraventricular nucleus have been reported to be increased. Moreover, OT is considered as an endogenous antistress hormone. It has also revealed antidepressive effects. OT may contribute to the dysregulation of the HPA system ...
