To determine the relative importance of the confining geometry and nanoscopic length scale versus water/interface interactions, the dynamic interactions between water and interfaces are studied with ultrafast infrared spectroscopy. Aerosol OT (AOT) is a surfactant that can form two-dimensional lamellar structures with known water layer thickness as well as well-defined monodispersed spherical r...

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...

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: Ei...

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 (ctrl)...

Operation Theatre (OT) is the most important area where precise controlled on indoor air quality is required because it is directly related to patient health and its recovery period. This work aims to study and visualize the airflow distribution of conventional flat air diffuser ventilation system and newly designed angular air ventilation system in OT. Angular Air Distribution (AAD) system is ...

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...

Last summer, AAAI sponsored a mobile robot competition in conjunction with the AAAI-92 conference in San Jose, California. Ten robots from across the country competed in the competition, with CARMEL from the University of Michigan finishing first. CARMEL is a Cybermotion K2A mobile platform with a ring of 24 sonar sensors and a single black and white CCD camera. For computing, CARMEL has three ...

The hypothalamic synthetic pathway of oxytocin (OT) involves the synthesis of carboxy-extended forms that serve as intermediate prohormones. We hypothesized that extended forms of OT are synthesized in the late-gestational rat uterus and that they compete for OT receptor binding. Parturition occurs only when the ratio of OT to its extended forms reaches a critical level. We have measured OT and...
