Differences in the in vitro sensitivity of ovine myometrium and mesometrium to oxytocin and prostaglandins E2 and F2alpha

Autor: M, Baguma-Nibasheka, R A, Wentworth, L R, Green, S L, Jenkins, P W, Nathanielsz

Publikováno v: Biology of reproduction. 58(1)

We compared the in vitro response to oxytocin, prostaglandin (PG)E2, and PGF2alpha of myometrium and mesometrium from six ovariectomized ewes and 53 ewes at 106-145 days gestational age (dGA), including 14 ewes in spontaneous or betamethasone-induced

Effect of in vivo estradiol administration to bilaterally ovariectomized rats on in vitro myometrial responsiveness to prostaglandin F2alpha and oxytocin

Autor: P L, Gordan, S L, Jenkins, R A, Wentworth, P W, Nathanielsz

Publikováno v: Biology of reproduction. 57(3)

Bilaterally ovariectomized, nonpregnant female CD rats were studied to investigate the effect of estradiol treatment on in vitro myometrial responsiveness to oxytocin and prostaglandin F2alpha. The first study investigated dose-dependent effects. Sev

Timing of the switch from myometrial contractures to contractions in late-gestation pregnant rhesus monkeys as recorded by myometrial electromyogram during spontaneous term and androstenedione-induced labor

Autor: D M, Farber, D A, Giussani, S L, Jenkins, C A, Mecenas, J A, Winter, R A, Wentworth, P W, Nathanielsz

Publikováno v: Biology of reproduction. 56(2)

Pregnant rhesus monkeys were studied to determine the precise time in relation to photoperiod of the onset, and the nature, of the switch in myometrial activity patterns from contractures to contractions. We investigated both spontaneous term labor a

Evidence for the presence of AH 13205-sensitive EP2-prostanoid receptors in the pregnant baboon but not in the pregnant sheep myometrium near term

Autor: R, Garcia-Villar, L R, Green, S L, Jenkins, R A, Wentworth, R A, Coleman, P W, Nathanielsz

Publikováno v: Journal of the Society for Gynecologic Investigation. 2(1)

Our purposes were to assess the effects of prostaglandin (PG) E2 and PGF2 alpha on myometrial contractility in pregnant sheep and baboons in an in vitro superfusion study, and to characterize further the PGE-sensitive (EP) receptor subtype involved i

Temporal structuring of delivery in the absence of a photoperiod: preparturient myometrial activity of the rhesus monkey is related to maternal body temperature and depends on the maternal circadian system

Autor: M B, Honnebier, S L, Jenkins, R A, Wentworth, J P, Figueroa, P W, Nathanielsz

Publikováno v: Biology of reproduction. 45(4)

No convincing evidence exists that the shift from myometrial contractures to contractions, which determines the synchronized 24-h rhythm in the dynamics of the primate uterus, may be attributed to an endogenous circadian rhythm. We therefore wished t

The Renal Excretion of Iodine Following Oral Administration of Gastrografin to Domestic Cats

Autor: Victor T. Rendano, R A Wentworth, M Marmor, P. C. Meunier, G. S. Allan

Publikováno v: Investigative Radiology. 15:47-51

Serum and urinary levels of iodine were determined in six cats before and after oral administration of Gastrografin. Iodine was identified by gamma spectrometry after the specimens had been subjected to neutron activation. Peak serum iodine levels, c

Hydromagnetic emissions, X-ray bursts, and electron bunches: 1. Experimental results

Autor: L. R. Tepley, R. C. Wentworth

Publikováno v: Journal of Geophysical Research. 67:3317-3333

Recent experimental results are presented concerning the occurrence, structure, and frequency-latitude dependence of hydromagnetic emissions (regular oscillatory micropulsations in the frequency range 0.4–7 cps). Results are also presented for the
