Organic Analysis at the Hanford Nuclear Site

Autor: M.R. Smith, T.E. Jones, R.M. Bean, H. Babad, J.A. Campbell, D.M. Strachan, D.W. Koppenaal, R.W. Stromatt

Publikováno v: Analytical Chemistry. 66:1208A-1215A

Of all the nuclear weapons production facilities in the United States, the Hanford site currently accounts for the largest volume percentage of defense-related high-level waste (HLW). After approximately 40 years of nuclear weapons production, Hanfor

The self-priming action of LHRH is under negative FSH control through a factor released by the ovary: observations in female rats in vivo

Autor: J. de Koning, J.A.M.J. van Dieten, A. M. I. Tijssen, D.W. Koppenaal

Publikováno v: Journal of Endocrinology. 129:205-211

Female rats were treated with Metrodin (highly purified urinary FSH from menopausal women) or saline during the oestrous cycle. On the day of pro-oestrus they were anaesthesized with phenobarbital and received four repetitive LHRH injections 1 h apar

Effect of x-irradiation on growth and the expression of parathyroid hormone-related peptide and Indian hedgehog in the tibial growth plate of the rat

Autor: Marcel Karperien, J.M. Wit, B.C.J. van der Eerden, Boudewijn Bakker, D.W. Koppenaal

Publikováno v: Hormone research. 59(1)

Aim: To study the effect of irradiation on the longitudinal growth and the expression of parathyroid hormone-related peptide (PTHrP) and Indian hedgehog (IHh) in tibial growth plates of rats. Methods: At 3 weeks of age, 30 male rats received a single

On the dynamics between gonadotrophin surge-inhibiting factor and gonadotrophin releasing hormone (GnRH): role of self-priming and desensitization in the luteinizing hormone response to GnRH after follicle stimulating hormone treatment

Autor: W.E. Westhoff, J. de Koning, J.A.M.J. van Dieten, D.W. Koppenaal

Publikováno v: Human reproduction (Oxford, England). 9(9)

The effects were studied of follicle stimulating hormone (FSH)-induced production of gonadotrophin surge-inhibiting factor (GnSIF) on three phases of the pituitary responsiveness to gonadotrophin releasing hormone (GnRH): the unprimed, primed and des

Induction of the gonadotrophin surge-inhibiting factor by FSH and its elimination: a sex difference in the efficacy of the priming effect of gonadotrophin-releasing hormone on the rat pituitary gland

Autor: D.W. Koppenaal, J. de Koning, J.A.M.J. van Dieten, A. M. I. Tijssen

Publikováno v: The Journal of endocrinology. 138(2)

This study was designed to explore the efficacy of gonadotrophin-releasing hormone (GnRH) to antagonize the effect of gonadotrophin surgeinhibiting factor (GnSIF) on the timing of the induction by GnRH of the maximal self-priming effect on pituitary

The effect of gonadotrophin surge-inhibiting factor on the self-priming action of gonadotrophin-releasing hormone in female rats in vitro

Autor: D.W. Koppenaal, J. de Koning, A. M. I. Tijssen

Publikováno v: The Journal of endocrinology. 134(3)

The present study was designed to explore further the functional antagonism between gonadotrophin-releasing hormone (GnRH) and the ovarian factor, gonadotrophin surge-inhibiting factor (GnSIF). In all experiments, pituitary tissue was exposed to vari
