Prediction of clinical outcome in patients with non-ST-elevation acute coronary syndrome (NSTE-ACS) using the TIMI risk score extended by N-terminal pro-brain natriuretic peptide levels
Jarai R, Iordanova N, Jarai R, Jarai F, Raffetseder A, Woloszczuk W, et al.
Wien Klin Wochenschr . 2007 Nov; 119(21-22):626-32. PMID: 18043882
Background: N-terminal pro-brain natriuretic peptide (Nt-proBNP) is a strong independent predictor of death in acute coronary syndromes. In order to improve risk assessment in patients with unstable coronary artery disease...

Endurance running acutely raises plasma osteoprotegerin and lowers plasma receptor activator of nuclear factor kappa B ligand
Ziegler S, Niessner A, Richter B, Wirth S, Billensteiner E, Woloszczuk W, et al.
Metabolism . 2005 Jul; 54(7):935-8. PMID: 15988704
Abstract The balance of the 2 cytokines, osteoprotegerin (OPG) and the receptor activator of nuclear factor kappa B ligand (soluble (s)RANKL), is known to have considerable influence on bone formation...

The age-related down-regulation of the growth hormone/insulin-like growth factor-1 axis in the elderly male is reversed considerably by donepezil, a drug for Alzheimer's disease
Obermayr R, Mayerhofer L, Knechtelsdorfer M, Mersich N, Huber E, Geyer G, et al.
Exp Gerontol . 2005 Mar; 40(3):157-63. PMID: 15763392
GH secretion declines by 14%/decade of adult life, leading to the suggestion that people over the age of 60 years are functionally GH deficient. Recently, rivastigmine, a novel cerebral selective...

Risk assessment in patients with unstable angina/non-ST-elevation myocardial infarction and normal N-terminal pro-brain natriuretic peptide levels by N-terminal pro-atrial natriuretic peptide
Jarai R, Iordanova N, Jarai R, Raffetseder A, Woloszczuk W, Gyongyosi M, et al.
Eur Heart J . 2004 Dec; 26(3):250-6. PMID: 15618049
Aims: To compare the accuracy of the N-terminal fragment of its pro-hormone (Nt-proBNP) and N-terminal pro-atrial natriuretic peptide (Nt-proANP) in the prediction of the 2 year mortality and to investigate...

The cholinergic system controls ghrelin release and ghrelin-induced growth hormone release in humans
Maier C, Schaller G, Buranyi B, Nowotny P, Geyer G, Wolzt M, et al.
J Clin Endocrinol Metab . 2004 Sep; 89(9):4729-33. PMID: 15356087
The stomach-derived peptide hormone ghrelin induces appetite and GH release. Several ghrelin actions are possibly mediated and modulated by the central cholinergic system. The aim of this study was to...

Effects of 12 months of recombinant growth hormone therapy on parameters of bone metabolism and bone mineral density in patients on chronic hemodialysis
Kotzmann H, Riedl M, Pietschmann P, Schmidt A, Schuster E, Kreuzer S, et al.
J Nephrol . 2004 May; 17(1):87-94. PMID: 15151263
Background: Renal osteodystrophy is common in patients with chronic renal failure (CRF) on hemodialysis (HD), leading to reduced bone mineral density (BMD) and higher bone fracture incidences. Since growth hormone...

Normal regulation of elevated plasma ghrelin concentrations in dialysis patients
Schmidt A, Fabrizii V, Maier C, Riedl M, Schmidt A, Kotzmann H, et al.
Wien Klin Wochenschr . 2004 May; 116(7-8):235-9. PMID: 15143862
Background: Chronic renal failure is often associated with malnutrition, and malnourished patients are subject to increased morbidity and mortality. Therefore plasma concentrations of the stomach-derived peptide hormone ghrelin, which has...

Increases in plasma levels of atrial and brain natriuretic peptides after running a marathon: are their effects partly counterbalanced by adrenocortical steroids?
Niessner A, Ziegler S, Slany J, Billensteiner E, Woloszczuk W, Geyer G
Eur J Endocrinol . 2003 Dec; 149(6):555-9. PMID: 14640997
Objective: Long-distance running results in considerable stress. Little evidence exists about the role of the atrial and brain natriuretic peptides, ANP and BNP, deriving from the myocardium. The aim of...

The reduced release of GH by GHRH in 8 subjects aged 65-69 years is augmented considerably by rivastigmine, a drug for Alzheimer's disease
Obermayr R, Mayerhofer L, Knechtelsdorfer M, Tragl K, Geyer G
Gerontology . 2003 Apr; 49(3):191-5. PMID: 12679611
Background: The growth hormone (GH) secretion declines by 14% with each decade of adult life. Several attempts have been made to reverse the manifestations of the senile GH deficiency, termed...

One-year growth hormone therapy improves granulocyte function without major effects on nutritional and anthropometric parameters in malnourished hemodialysis patients
Kotzmann H, Schmidt A, Lercher P, Schuster E, Geyer G, Frisch H, et al.
Nephron Clin Pract . 2003 Mar; 93(2):C75-82. PMID: 12616034
Background/aims: Growth hormone (GH) resistance leads to enhanced protein catabolism and contributes to the malnutrition of patients with chronic renal failure (CRF). In short-term trials anabolic effects of rhGH therapy...
