Differential recovery of prostacyclin and endothelium-derived relaxing factor after vascular injury. Am. J. Physiol. 262 (Heart Circ. Physiol. 31): H1449-H1457, 1992. The recovery of prostacyclin (prostaglandin I2, PGI2) synthesis and endothelium-derived relaxing factor (EDRF) activity, as demonstrated by acetylcholine (ACh)-induced relaxation, by rabbit(More)
This article explores the often perplexing experience of being an epilepsy surgery candidate, as portrayed in four book-length accounts: Laura Doermer's Moritz mein Sohn (Moritz my son, 1990), David B.'s L'ascension du haut mal (The ascent of the high evil, 1996; published in English as Epileptic, 2003), Ray Robinson's Electricity (2006), and Alberto(More)
The development of a long-acting delivery system for D-Phe-Cys-Tyr-D-Trp-Lys-Val-Cys-Trp-NH2 (RC-160), an octapeptide analog of somatostatin, required the establishment of a method for determining the concentration of this analog in serum during treatment. A sensitive and specific radioimmunoassay (RIA) for RC-160 was developed and used for following the(More)
Mice homozygous for the recessive 'Ames' dwarf mutation have undetectable serum or pituitary prolactin (PRL). Accompanying this pituitary deficiency is a marked reduction of dopamine (DA) and its rate-limiting synthetic enzyme tyrosine hydroxylase (TH) in PRL-regulating tuberoinfundibular hypothalamic neurons. In order to determine whether this deficit in(More)
"Public Trust in Expert Knowledge: Narrative, Ethics, and Engagement" examines the social, cultural, and ethical ramifications of changing public trust in the expert biomedical knowledge systems of emergent and complex global societies. This symposium was conceived as an interdisciplinary project, drawing on bioethics, the social sciences, and the medical(More)
Hypothalamic tuberoinfundibular prolactin-inhibiting neurons show decreased levels and synthesis of dopamine in two types of genetically prolactin-deficient dwarf mice (Snell, Ames) which arise from separate mutations. A reduction to 2% of normal in this neuronal population has been quantified for Snell dwarfs. The present study was undertaken in order to(More)
Development of the hypophysiotropic hypothalamus in PRL-deficient Ames dwarf (df/df) mice was examined for steady state dopamine (DA) by visualization using formaldehyde-induced catecholamine histofluorescence and by quantification using catecholamine HPLC at selected postnatal ages (7, 14, 21, 30, and 90 days). Phenotypically normal (DF/?) littermate mice(More)
