(Pro)renin receptor [(P)RR], a specific receptor for renin and prorenin, is a 350 amino acid protein with a single transmembrane domain. In the present study, the expression of (P)RR in the human brain and pituitary, and its co-localisation with arginine vasopressin and oxytocin in the human hypothalamus were studied by quantitative reverse transcriptase(More)
An adrenal pheochromocytoma producing somatostatin (SRIF) and vasoactive intestinal polypeptide (VIP) in a 17-year-old boy is presented. High concentrations of immunoreactive (IR)-SRIF were found in plasma taken from the antecubital vein (31.0-33.0 pg/ml) and the inferior caval vein near the tumor (54.6 pg/ml), but after removal of the tumor the values(More)
Two patients with urinary calculi presented hypercalcemia with very moderate calciuria and serum parathormone levels. These cases are used as a basis for a description of the familial hypercalcemia-hypocalciuria syndrome reported by Marx, a dominant autosomal disease in which the hypercalcemia is associated with a moderate hypermagnesemia and normal renal(More)
BACKGROUND An effective ureteroileal reimplantation without reflux and obstruction is indispensable for lower urinary reconstruction or diversion using an ileal segment. Based on our earlier experience of afferent nipple valve malfunction of the Kock pouch, we performed Le Duc-Camey antireflux ureteroileal implantation. In the present study, we evaluated(More)
A growth hormone-releasing hormone (GHRH)-secreting pancreatic tumor in a 36-year-old man, who had typical, familial, multiple endocrine neoplasia (MEN) type I with hyperparathyroidism and acromegaly, is described. The resected tumor, weighing 30 g, showed unusual histological features characterized by a meningioma-like arrangement of crescent-shaped cells(More)
