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...

BACKGROUND Oxytocin (OT) is synthesized as a prohormone that is sequentially processed to peptides. These peptides are the bioactive amidated form (OT) and the C-terminal extended peptides, OT-Gly, OT-Gly-Lys and OT-Gly-Lys-Arg, which are designated together as OT-X. As an extension of our previous study finding decreased plasma OT in autism, studies were conducted to determine whether there we...

BACKGROUND Oxytocin (OT), synthesized in the heart, has the ability to heal injured hearts and to promote cardiomyogenesis from stem cells. Recently, we reported that the OT-GKR molecule, a processing intermediate of OT, potently increased the spontaneous formation of cardiomyocytes (CM) in embryonic stem D3 cells and augmented glucose uptake in newborn rat CM above the level stimulated by OT. ...

in this research degradation and mineralization of ortho-toluidine (ot) in the wastewater of petrochemical industries was investigated by uv/tio 2 process in a batch recirculating photo reactor. the influence of different variables such as initial ph, amount of tio 2 and initial concentration of ot on the reaction rate was investigated. in optimum conditions (1.75 g/l of catalyst, ph at 7 and i...

For a long time, the hypothalamic nonapeptide oxytocin (OT) is known to play a crucial role in many reproductive and behavioral functions. In recent years, a new biological effect of OT has been identified in neoplastic pathology. In this context, OT acts as a growth regulator. through the activation of specific G-coupled transmembrane receptors (OTR). In vitro, an antiproliferative effect of O...
