Diterpenes have recently received a great deal of interest as tools to investigate the botanical origin of coffee. Specifically, kahweol has been proposed as a marker of Coffea arabica while 16-O-methylcafestol (16-OMC) is a Coffea canephora specific marker and its detection and quantification allow the authenticity of pure C. arabica roasted coffee blends to be assessed. In this study, we evaluated...

In this work, several aroma precursors present in Moscato Giallo grape juice were identified and characterized using LC–MS and NMR techniques. A preliminary separation of various fractions was obtained using adsorption on Amberlite ^® XAD resin and HPLC chromatography on a reverse phase column. Subsequently, U-HPLC with mass spectrometry allowed the identification of some compounds corresponding...

Aim: This study assessed the efficacy of long‐term l‐arginine (l‐arg) therapy in preventing or delaying type 2 diabetes mellitus. Methods: A mono‐centre, randomized, double‐blind, parallel‐group, placebo‐controlled, phase III trial (l‐arg trial) was conducted on 144 individuals affected by impaired glucose tolerance (IGT) and metabolic syndrome (MS). l‐Arg/placebo was administered (6.4 g/day) on a...

The N-terminal 1–34 segment of parathyroid hormone (PTH) is fully active in vitro and in vivo and it elicits all the biological responses characteristic of the native intact PTH. Recent studies reported potent helical analogues of the PTH (1–11) with helicity-enhancing substitutions. This work describes the synthesis, biological activity, and conformational studies of analogues obtained from the most...
