Increased cholinergic tone induced by pyridostigmine (PD) increases basal plasma GH levels and potentiates the GH response to GHRH in normal adults. In this study the effects of PD (60 mg, orally) on both basal and GHRH (1 microgram/kg)-induced GH secretion in seven children with familial short stature (FSS), six with GH deficiency (GHD) and 10 with(More)
Three cases of connective tissue tumors causing hypophosphatemic osteomalacia are reported and the literature is reviewed. In two of our patients the tumors were completely excised with total disappearance of the symptoms. In one case a total excision was not possible and the symptoms of this patient have not completely disappeared. The substance(More)
The function of the growth hormone-insulin-like growth factor I (GH-IGF-I) axis is reduced in aging, although the secretory capacity of somatotrope cells is preserved. Previous studies have suggested that continuous administration of GH-releasing peptides (GHRPs) results in homologous desensitization to the GH-releasing effect of the peptides. In the(More)
In man the GH-releasing hexapeptide His-DTrp-Ala-Trp-DPhe-Lys-NH2 (GHRP-6) has been shown to be active even after oral administration. On the other hand, it has been shown that arginine (ARG) totally restores the reduced somatotropic responsiveness to GHRH observed in aging. Based on the foregoing, in this study we verified the GH-releasing activity of oral(More)
Previously, we discovered linomide analogues as novel HIV-1 integrase (IN) inhibitors. Here, to make possible structure-activity relationships, we report on the design and synthesis of a series of substituted dihydroquinoline-3-carboxylic acids. The crystal structure of the representative compound 2c has also been solved. Among the eight new analogues, 2e(More)
BACKGROUND Left ventricular hypertrophy (LVH) appears to be poorly correlated with clinical measurements of blood pressure: a better correlation may be observed with data from 24 h ambulatory blood pressure monitoring (ABPM). The aim of this study was to compare the results of non-invasive ABPM in a population of patients with essential hypertension who had(More)
The hipopituitarim's treatment is in want to use the hormonal replacement with corticosteroid and l-tiroxine in all patients. The exogenous gonadotropin or sexual hormones are administrated in both sexes in different way for different ages. The pituitary dwarfism secondary to GH deficiency is now cured with the syntetic GH use. The DDAVP is the drug of(More)
