Phenacetin (1), acetaminophen (2), acetanilide (3), 4-aminophenol (4), and aniline (5) were tested in S.J.L. Swiss mice for their mutagenic and analgesic activities. The S-analogues of 1 and 2, 4-mercaptoacetanilide (6) and 4-ethylthioacetanilide (7), respectively, were synthesized and tested in the same way to define if both activities could be separated(More)
The potential of Fourier transform mid-infrared spectroscopy (FT-MIR) using an attenuated total reflectance (ATR) cell was evaluated for the authentication of 11 unifloral (acacia, alpine rose, chestnut, dandelion, heather, lime, rape, fir honeydew, metcalfa honeydew, oak honeydew) and polyfloral honey types (n = 411 samples) previously classified with(More)
The amino acid composition of 53 honey samples from Spain, consisting of 39 floral, 5 honeydew, and 9 blend honeys, has been determined. Physicochemical characteristics, polyphenolic content, amino acid composition, and estimation of the radical scavenging capacity against the stable free radical DPPH of the honey samples were analyzed. The resulting data(More)
With the aim of finding methods that could constitute a solid alternative to melissopalynological and physicochemical analyses to determine the botanical origin (floral or honeydew) of honeys, the free amino acid content of 46 honey samples has been determined. The honeys were collected in a small geographic area of approximately 2000 km(2) in central(More)
This study was carried out to establish the changes in the free amino acid contents of floral honeys, honeydew honeys, and blend honeys during storage at room temperature and to test the capacity of the amino acids to distinguish the origin of the honeys after storage. For this purpose, 54 artisanal honeys (39 floral, 5 honeydew, and 10 blend) were studied.(More)
PURPOSE To assess the efficacy of petrolatum jelly for the prevention of diaper rash and to evaluate the relationship between the occurrence of diaper rash and certain treatments and type of nutrition. DESIGN AND METHODS A randomized clinical trial was carried out with two parallel groups (n = 213) at the neonatal care unit of Donostia University Hospital(More)
Genetic Algorithms (GA) are a mathematical tool based on the mechanisms of the evolution of species and are successfully applied mainly as function optimizers. They look for the most fit solution for a particular problem, by means of the evolution of populations of data that, once codified –generally a binary encoding– use genetic operators which(More)
