This study examined the effect of bovine colostrum (Dynamic colostrum) supplementation on blood and saliva variables (study 1) and the absorption of orally administered human recombinant insulin-like growth factor (IGF)-I (rhIGF-I) labeled with 123I (123I-rhIGF-I) (study 2). In study 1, adult male and female athletes were randomly assigned in a double-blind fashion to either an experimental (Dy...
The negative feedback exerted by insulin-like growth factor I (IGF-I) on GH secretion occurs at the pituitary, as well as the hypothalamic level, via stimulation of SS and/or inhibition of GHRH release. In fact, recombinant human IGF-I (rhIGF-I) administration inhibits basal GH secretion, at least in fasted humans, though its effect on the GH response to GHRH is still controversial. GH secretag...
The aim of this study was to investigate whether apoptosis contributes to nephrotoxicity caused by amphotericin B (AmB). By detecting apoptosis-specific DNA fragmentation, it is demonstrated that proximal tubular cells (LLC-PK(1)) and medullary interstitial cells (RMIC) respond with programmed cell death when treated with therapeutic doses of AmB. Concomitant application of AmB and recombinant ...
CONTEXT Acid labile subunit (ALS) deficiency, caused by IGFALS mutations, is a subtype of primary IGF-I deficiency (PIGFD) and has been associated with insulin resistance (IR) and osteopenia. Whether patients respond to recombinant human IGF-I (rhIGF-I) is unknown. OBJECTIVE AND DESIGN This study determined the 14-hour pharmacokinetic response of free and total IGF-I and IGF binding protein 3...
Objective To measure the efficacy of mecasermin (recombinant human insulin-like growth factor 1, rhIGF-1), for treating symptoms of Rett syndrome (RTT) in a pediatric population using a double-blind crossover study design. Methods Thirty girls with classic RTT in postregression stage were randomly assigned to placebo or rhIGF-1 in treatment period 1 and crossed over to the opposite assignment...
This study examined the effect of bovine colostrum (Dynamic Colostrum) supplementation on blood and saliva variables (study 1) and the absorption of orally administered human recombinant IGF-1 (rhIGF-1) labeled with 123 iodine (study 2). In study 1 adult male and female athletes were randomly assigned in a double-blind fashion to either an experimental (Dynamic; n=19) or a control (Placebo; n=...
Sexually dimorphic growth hormone (GH) secretory pattern is important in the determination of gender-specific patterns of growth and metabolism in rats. Whether GH secretion in humans is also sexually dimorphic and the neuroendocrine mechanisms governing this potential difference are not fully established. We have compared pulsatile GH secretion profiles in young men and women in the baseline s...
Renal failure is associated with dramatic changes in the growth hormone/insulin-like growth factor (GH/IGF) axis. In children, this results in growth retardation, which is treated with injections of recombinant human GH (rhGH). Given the many recent advances in the knowledge of the components of the GH/IGF axis, it is timely to review the role of GH in renal failure and to discuss likely new tr...
