Non-canonical regulation of glutathione and trehalose biosynthesis characterizes non-Saccharomyces wine yeasts with poor performance in active dry ye…
2018
Several yeast species, belonging to Saccharomyces and non-Saccharomyces genera, play fundamental roles during spontaneous must grape fermentation, and recent studies have shown that mixed fermentations, co-inoculated with S. cerevisiae and non-Saccharomyces strains, can improve wine organoleptic properties. During active dry yeast (ADY) production, antioxidant systems play an essential role in yeast survival and vitality as both biomass propagation and dehydration cause cellular oxidative stress and negatively affect technological performance. Mechanisms for adaptation and resistance to desiccation have been described for S. cerevisiae, but no data are available on the physiology and oxidat…
COMBINATION OF ARGAN OIL AND PHOSPHOLIPIDS FOR THE DEVELOPMENT OF AN EFFECTIVE LIPOSOME-LIKE FORMULATION ABLE TO IMPROVE SKIN HYDRATION AND ALLANTOIN…
2016
Allantoin is traditionally employed in the treatment of skin ulcers and hypertrophic scars. In the present work, to improve its local deposition in the skin and deeper tissues, allantoin was incorporated in conventional liposomes and in new argan oil enriched liposomes. In both cases, obtained vesicles were unilamellar, as confirmed by cryo-TEM observation, but the addition of argan oil allowed a slight increase of the mean diameter (∼130nm versus ∼85nm). The formulations, especially those containing argan oil, favoured the allantoin accumulation in the skin, in particular in the dermis (∼8.7μg/cm(2)), and its permeation through the skin (∼33μg/cm(2)). The performances of vesicles as skin d…
Food-grade argan oil supplementation in molasses enhances fermentative performance and antioxidant defenses of active dry wine yeast
2015
The tolerance of the yeast Saccharomyces cerevisiae to desiccation is important for the use of this microorganism in the wine industry, since active dry yeast (ADY) is routinely used as starter for must fermentations. Both biomass propagation and dehydration cause cellular oxidative stress, therefore negatively affecting yeast performance. Protective treatments against oxidative damage, such as natural antioxidants, may have important biotechnological implications. In this study we analysed the antioxidant capacity of pure chemical compounds (quercetin, ascorbic acid, caffeic acid, oleic acid, and glutathione) added to molasses during biomass propagation, and we determine several oxidative …
Giacomo Serpotta tra sacro e profano
2022
We shall be taking an innovative and original approach in our examination of the insuperable figure of Giacomo Serpotta, an outstanding Sicilian stucco sculptor of the 18th century. The complete artistic output of Giacomo Serpotta is traced, oscillating between the sacred and the profane in the sculptural adornment of many churches and oratories. Here, Giacomo Serpotta shifts from the Baroque to Rococo, originating a sculptural art that is profoundly innovative in its language and symbology. Formal reading and chromatic-spatial games are intertwined with the symbolic in the light of significant essays by Carl Gustav Jung, Martin Heidegger and Carlo Giulio Argan
Argan oil prevents down-regulation induced by endotoxin on liver fatty acid oxidation and gluconeogenesis and on peroxisome proliferator-activated re…
2015
In patients with sepsis, liver metabolism and its capacity to provide other organs with energetic substrates are impaired. This and many other pathophysiological changes seen in human patients are reproduced in mice injected with purified endotoxin (lipopolysaccharide, LPS). In the present study, down-regulation of genes involved in hepatic fatty acid oxidation (FAOx) and gluconeogenesis in mice exposed to LPS was challenged by nutritional intervention with Argan oil. Mice given a standard chow supplemented or not with either 6% (w/w) Argan oil (AO) or 6% (w/w) olive oil (OO) prior to exposure to LPS were explored for liver gene expressions assessed by mRNA transcript levels and/or enzyme a…

Le arti decorative in Sicilia negli anni di Argan

Si ricostruiscono gli studi dedicati alle arti decorative siciliane nel periodo di permanenza in Sicilia di Giulio Carlo Argan
Argan e Giacomo Serpotta
2013
Il testo, frutto dell’intervento tenuto alla giornata di studi su Giulio Carlo Argan, docente di Storia dell’Arte all’università di Palermo tra il 1955 e il 1959, prende in esame un suo breve ma fondamentale contributo sullo scultore-stuccatore palermitano Giacomo Serpotta (1656-1752) scritto nel 1957. L’analisi critica del testo, interpretando la densità dei concetti espressi dal critico e storico dell’arte, mette in evidenza gli aspetti salienti della critica arganiana sull’argomento. Si rileva come Argan voli subito molto alto ed tracci delle interpretazioni ancora estremamente valide, come anche alcune letture complesse e di certo avvincenti, che pongono in ulteriore luce l’arte del mae…
