Effects of pulsed high-frequency electromagnetic fields on the neuroendocrine system.
1998
The influence of pulsed high-frequency electromagnetic fields emitted from a circularly polarized antenna on the neuroendocrine system in healthy humans was investigated (900 MHz electromagnetic field, pulsed with 217 Hz, average power density 0.02 mW/cm<sup>2</sup>). Nocturnal hormone profiles of growth hormone (GH), cortisol, luteinizing hormone (LH) and melatonin were determined under polysomnographic control. An alteration in the hypothalamo-pituitary-adrenal axis activity was found with a slight, transient elevation in the cortisol serum level immediately after onset of field exposure which persisted for 1 h. For GH, LH and melatonin, no significant effects were found under…

The role of physical activity on postural stability and fitness characteristics in pediatric patients with GH deficiency
2019
Purpose: Patients with growth hormone deficiency (GHD) show low fitness levels before GH treatment is started. Muscular strength, flexibility and postural stability are related to health and quality of life. Since it is widely recognized that physical activity increases GH secretion and GH could ameliorate fitness, if a high adherence to treatment is documented (1), the purpose of this study is to investigate any difference on posturographic parameters and muscular features in physically active children with GHD, treated with GH with a high adherence to the treatment, and compared with sedentary pediatric patients. Methods: 13 children (7 males, 6 females) with GHD were enrolled at the Univ…
Influence of muscle strength and total work on exercise-induced plasma growth hormone isoforms in women
2003
The purpose of this investigation was to determine the influence of physical strength and the ability to do more total work on human growth hormone (GH) variants to a heavy resistance exercise protocol in untrained women. From a distribution of 100 healthy, untrained women, the strongest 10 women (S) and the weakest 10 women (W) were compared for GH responses pre- and post an acute heavy resistance exercise test (AHRET, 6 sets of 10 RM squats, 2 minutes rest between sets). Blood samples were obtained pre-exercise and immediately post-exercise and subsequently analysed in total as well as fractionated by Sephacryl S-100R column chromatography into three molecular weight size classes: fractio…
Effects of high-intensity training on physiological and hormonal adaptions in well-trained cyclists
2017
Purpose: This study aimed to compare the effects of three different high-intensity training (HIT) models, balanced for total load but differing in training plan progression, on endurance adaptations. Methods: Sixty-three cyclists (peak oxygen uptake (V˙ O2peak) 61.3 T 5.8 mLIkgj1 Iminj1 ) were randomized to three training groups and instructed to follow a 12-wk training program consisting of 24 interval sessions, a high volume of low-intensity training, and laboratory testing. The increasing HIT group (n = 23) performed interval training as 4 16 min in weeks 1–4, 4 8 min in weeks 5–8, and 4 4 min in weeks 9–12. The decreasing HIT group (n = 20) performed interval sessions in the opposite me…
Interventions to Slow Aging in Humans: Are We Ready?
2015
The workshop entitled 'Interventions to Slow Aging in Humans: Are We Ready?' was held in Erice, Italy, on October 8-13, 2013, to bring together leading experts in the biology and genetics of aging and obtain a consensus related to the discovery and development of safe interventions to slow aging and increase healthy lifespan in humans. There was consensus that there is sufficient evidence that aging interventions will delay and prevent disease onset for many chronic conditions of adult and old age. Essential pathways have been identified, and behavioral, dietary, and pharmacologic approaches have emerged. Although many gene targets and drugs were discussed and there was not complete consens…
Metabolic effects of GH therapy in adults with GH deficiency: a 2 year prospective study
2015
Background Growth hormone deficiency (GHD) in adults is associated with adverse metabolic profile, while data about the metabolic effects of GH treatment are controversial. Aim To evaluate the metabolic influence of GH replacement in GHD. Subjects and Methods Data of 65 patients (35 M, age 54 ± 18 yrs) were analyzed. Before GH therapy and yearly up to 2 years we measured BMI, WC, visceral adiposity index (VAI), IGF-1, lipide profile, HbA1c and basal insulin-secretion (Homa-β) and -sensitivity (Homa-IR) indexes. Results No subject showed overt dysglycemia at baseline and during GH therapy. Hypertriglyceridemia was detected in 36 patients at baseline and in 31 and 20 respectively at 12 and 24…

Growth performance in heavy lambs experimentally treated with 17 β-estradiol
2012
European and Italian legislation have banned use of growth promoters in livestock since 1988, but epidemiological data show that anabolic drugs are still being used illegally. Recent surveys carried out on the cattle farms in Northern Italy have confirmed the presence of growthpromoting hormones. Authors report data on growth performances in 80 Valle del Belice×Comisana weaned lambs experimentally treated with 17 beta-estradiol with 0.5 ml solution of oil Depot Estradiol ® (containing 5 mg of 17β- estradiol valerate) by intramuscular injection into the thigh. The experiment was founded by the National Ministry of Health, to validate histological test for surveillance and control of growth-p…
Die Bestimmung von Wachstumshormon (HGH) als Diagnosticum bei chromophoben und eosinophilen Adenomen der Hypophyse
1971
Der Wert der radioimmunologischen Bestimmung von Wachstumshormon (HGH) in der praoperativen Diagnostik von chromophoben und eosinophilen Adenomen der Hypophyse wird an 27 Fallen demonstriert. Als Funktionstest wird die Insulin-induzierte Hypoglykamie angewandt. Eine einfache Maszahl (FHGH) zur Auswertung der Ergebnisse wird vorgeschlagen, die durch Integration der Flachen unter den HGH-Kurven erhalten wird. Als indirekte Testverfahren zur Uberprufung der Hypophysenfunktion dienen ein Metopiron- und ein ACTH-Test.
