The selected ion flow tube technique was used to quantify in breath the trace gases acetone, ammonia, ethanol, isoprene, and methanol during single exhalations while fasting and in response to feeding. Six normal volunteers were fasted for 12 h, and, after baseline breath samples were obtained, were fed a liquid protein-calorie meal to provide 0.47 g/kg of protein (Fortisip). Further breath sam...

Background: The halophyte Lotus creticus L. (creta trefoil, Fabaceae) belongs to a family and genus containing several medicinal species, is considered promising crop for saline Mediterranean areas. However, the best of our knowledge, information regarding biological properties this species that could increase its biotechnological value particularly scarce. Objectives: We aimed evaluate potenti...

The application of conservation treatments on archaeological bone is, in many cases, a necessary step for its study. Cleaning interventions can generate modifications the surface material or even modify elements variables involved this process have been scarcely characterized. present study reports characterization how different liquids commonly used cleaning processes contribute to onset by in...

A previous study suggested the usefulness of pericardial fluid (PCF) and bone marrow aspirate (BMA) for the postmortem analysis of ethanol. The present study reviewed forensic autopsy cases (n = 2,983), which included 683 cases with the following positive toxicological findings, to reassess ethanol distribution and to investigate other gaseous and volatile substances in blood, PCF and BMA. Toxi...

BACKGROUND The aim of this study was to identify, quantify, and compare the phytochemical contents, antioxidant capacities, and antibacterial activities of Aloe vera lyophilized leaf gel (LGE) and 95% ethanol leaf gel extracts (ELGE) using GC-MS and spectrophotometric methods. RESULTS Analytically, 95% ethanol is less effective than ethyl acetate/diethyl ether or hexane (in the case of fatty ...
