OBJECTIVES Oxytocin (OXY) in addition to peripheral actions has many central regulatory functions which can be studied on animal models. In the present study we examined in rats, which behavioral actions of OXY and long-acting carba-analog of OXY carbetocin (CBT) in the open-field can be inhibited by OXY-receptor antagonists. Our interest focused on the behavioral patterns considered indicative...

Opioid conjugate vaccines have shown promise in attenuating the behavioral effects of heroin or morphine in animals. The goal of this study was to extend this approach to oxycodone (OXY), a commonly abused prescription opioid. Haptens were generated by adding tetraglycine (Gly)(4) or hemisuccinate (HS) linkers at the 6-position of OXY. Immunization of rats with OXY(Gly)(4) conjugated to the car...

A blinded, randomised GCP study was performed to investigate the efficacy of a single injection of long-acting oxytetracycline (OXY) and flunixin (FLU) in young calves suffering from acute respiratory disease. Tilmicosine (TIL) and oxytetracycline alone were used as positive controls. Six hours post-treatment, rectal temperature in animals treated with OXY/FLU had decreased and was significantl...

The objectives of the study were to determine the pharmacokinetics of oxymorphone (oxy) and of ammonium sulfate-loaded, liposome-encapsulated oxymorphone (LE-ASG oxy) and to evaluate the behavioral effects of both opioid preparations by using ethographic evaluation specific to rhesus monkeys. Rhesus monkeys (n = 8) were injected with 2.0 mg/kg LE-ASG oxy s.c.. Blood samples were collected at se...

In the title compound, C12H12O7, the dihedral angles between the benzene ring and the mean planes of the 3-carb-oxy-meth-oxy, 1-carb-oxy-meth-oxy and acetyl substituents are 8.67 (7), 7.81 (6) and 10.3 (18)°, respectively. In the crystal, mol-ecules are linked by typical carb-oxy-lic acid O-H⋯O hydrogen bonds, forming a zigzag chain. C-H⋯O inter-actions also occur.

Arginine-vasopressin (AVP) and its associated neurophysin (AVP-NP) are synthesized via a precursor, propressophysin, which also contains a 39 amino acid glycopeptide at its C-terminus (C-terminus of propressophysin, or CPP). In the present study, immunocytochemical techniques were used to determine the cellular co-localization of CPP with AVP, oxytocin (OXY), AVP-NP and OXY-NP in the rat hypoth...

The hydr-oxy groups in the title compound, C(16)H(14)O(4), are each hydrogen bonded to the adjacent meth-oxy O atom; one of the two hydr-oxy groups is additionally linked to the O atom of the meth-oxy group of another mol-ecule, forming a linear chain.

Future use of coal for power generation in the US depends on technologies being made available to capture and store CO2 emissions from power plants. A key candidate CO2 capture technology is oxy-firing of coal. Application of oxy-firing to existing power plants presents unquantified challenges as the characteristics of oxy-firing compared to airfiring have not been fully determined. This presen...
