Effect of Pulsatile Intravenous Oxytocin Administration to Pregnant Sheep Over the Last Third of Gestation on Fetal ACTH and Cortisol Responses to Hypotension
Autor: Susan Zarzeczny, Peter W. Nathanielsz, James R. Owiny, D. W. Sadowsky
Publikováno v: Journal of the Society for Gynecologic Investigation. 2:13-18
OBJECTIVE To examine the effect of increasing myometrial contractility in the last third of gestation on ovine fetal response to hypotension. METHODS Oxytocin (600 microU/kg/minute) or saline was infused via the maternal jugular vein as 5-minute puls

Lack of Effect of Melatonin on Myometrial Electromyographic Activity in the Pregnant Sheep at 138–142 Days Gestation (Term = 147 Days Gestation)*
Autor: Peter W. Nathanielsz, D W Sadowsky, Steven M. Yellon, Murray D. Mitchell
Publikováno v: Endocrinology. 128:1812-1818
A 24-h rhythm has been demonstrated in fetal and maternal melatonin plasma concentrations in pregnant sheep in the last third of gestation. Melatonin in the maternal circulation can cross the placenta and is the major source of melatonin in the fetal

Progesterone receptor localization and isoforms in myometrium, decidua, and fetal membranes from rhesus macaques: evidence for functional progesterone withdrawal at parturition
Autor: G J, Haluska, T R, Wells, J J, Hirst, R M, Brenner, D W, Sadowsky, M J, Novy
Publikováno v: Journal of the Society for Gynecologic Investigation. 9(3)
It is not known whether withdrawal of progesterone (P) action is a prerequisite for parturition in women or in nonhuman primates because concentrations of circulating progesterone or progesterone receptors (PR) in myometrium and decidua do not decrea

Amniotic fluid prolactin is decreased by experimental intrauterine infection or interleukin-1beta infusion but not via prostaglandins in pregnant rhesus macaques
Autor: C L, Bethea, M G, Gravett, D W, Sadowsky, G J, Haluska, M K, Axthelm, M J, Novy, M K, Axethelm
Publikováno v: Biology of reproduction. 58(6)
Amniotic fluid contains a high concentration of prolactin produced and secreted by the decidua. In vitro models have suggested that bacterial products inhibit prolactin secretion by decidual cells. To further examine this potentially important regula

Effect of pulsatile oxytocin administration to the pregnant ewe in the last third of gestation on fetal ACTH and cortisol response to acute hypoxemia
Autor: Susan L. Jenkins, James R. Owiny, D. W. Sadowsky, P. W. Nathanielsz
Publikováno v: Journal of the Society for Gynecologic Investigation. 2(5)
OBJECTIVE The aim of this study was to examine the effect of increased myometrial contractility throughout the last third of pregnancy on the ovine fetal response to short-term hypoxemia. METHODS Oxytocin (600 microU/kg/minute, n = 5) or saline (n =

Prostaglandin endoperoxide-H synthase (PGHS) activity and immunoreactive PGHS-1 and PGHS-2 levels in human amnion throughout gestation, at term, and during labor
Autor: G. Machin, Tamas Zakar, B. Resch, Jonathan J. Hirst, David M. Olson, D. W. Sadowsky, Nestor Demianczuk, Fang Guo, F. J. Teixeira
Publikováno v: The Journal of clinical endocrinology and metabolism. 78(6)
Prostaglandins (PGs) are of primary importance in the initiation and maintenance of labor in women. A major intrauterine source of prostaglandins is the amnion, which synthesizes increased amounts of PGE2 at term labor. Because PG endoperoxide-H synt

Maintaining fetal normoglycemia prevents the increase in myometrial activity and uterine 13,14-dihydro-15-keto-prostaglandin F2 alpha production during food withdrawal in late pregnancy in the ewe
Autor: Audrey A. Kelleman, Zbigniew Binienda, Peter W. Nathanielsz, Murray D. Mitchell, Evan D. Rosen, D. W. Sadowsky
Publikováno v: Endocrinology. 127(6)
Food deprivation during pregnancy leads to an increase in maternal and fetal prostaglandin (PG) production and increased uterine contractility. We investigated the effect of maintaining fetal normoglycemia during food withdrawal-induced maternal hypo

Lack of effect of fetal administration of cocaine on maternal and fetal plasma adrenocorticotropin, cortisol and lactate concentrations at 127-138 days gestational age

CIÊNCIAVITAE
Few in vivo studies have attempted to characterize the effects of cocaine on the maternal and fetal pituitary-adrenal axis during pregnancy. We, therefore, administered cocaine (2 mg.kg-1) intravenously to 6 fetal sheep at 127-138 days of gestation.
