Districare gli stereotipi dal genere semantico in italiano. Un'indagine psicolinguistica
No full textOur contribution is the adaptation to Italian of the study conducted on French by Richy and Burnett in 2021 with the aim to answer two research questions: (i) To what extent does the cultural bias influence the interpretation of a gender-neutral nominal expression? (ii) Can masculine nouns designating definite, specific individuals be interpreted as referring to either a man or a woman? Our results show that neutralized nominals are interpreted according to the gender bias, while masculine nominals are interpreted as just referring to men. This indicates that in Italian, masculine role nouns do not refer to women and that neutralizing a gender language does not contrast gender inequalities

Antioxidants, reactive oxygen species and nutrition
No full textFree radicals and other oxygen-derived species (ROS) are constantly generated in vivo, both by "accidents of chemistry" and for specific metabolic purpose. The reactivity of different free radicals varies, but some can cause severe damage to biological molecules, especially to DNA, lipids and proteins. Oxidative damage to these molecules has been implicated in a wide variety of degenerative diseases such as atherosclerosis and cancer. The human body has powerful mechanisms for defence against free radicals and other reactive oxygen species. Components of both endogenous and exogenous origins contribute to protection, and new data suggests that the various defences are complementary to one another, so, they interact to spare or replace each other. Nevertheless the antioxidant defence systems are not 100% effective, the result is a condition called oxidative stress, that is an imbalance between pro-oxidant factors and antioxidants. Hence, diet-derived antioxidants may be particularly important in slackening cumulative oxidative damage and helping the human body to stay healthier for longer. Vitamin C is an effective scavenger of many oxyradicals in body's aqueous compartments such as blood plasma end cell cytosol. Vitamin E provides antioxidant protection in body's lipid phases, especially by protecting the unsaturated fatty acids of cell membranes and plasma lipoproteins. Carotenoids are also believed to provide antioxidant protection to lipid rich tissues. A variety of minor plant constituents (phytochemicals), such as flavonoids, exhibit antioxidant and free radical scavenging properties in vitro, suggesting a possible protective role in the human body. However, the mechanisms through which these compounds act in vivo are still incompletely understood and many uncertainties persist relative to their bioavailability and metabolic fate in human body. The progress of the studies in this particularly topic will have important repercussions both in the preventive medicine and in clear pathology. The possibility to taking protective components with foods is very important for health human body and even more for ill person. With respect to this, the enteral and parenteral nutrition, as specialized nutrition support during critical illness, will evolve in response to the results of studies regarding to the different antioxidants (exogenous and endogenous) interactions and synergisms. Moreover, will be investigated possible sinergisms and antagonisms between natural antioxidants and dietary components, as well as, other substances such as drugs or farmacological active molecules
CONJUGATED LINOLEIC ACID. A natural anticarcinogenic substance from animal food
No full textConjugated linoleic acid (CLA) is a natural component of animal food derived from linoleic acid. It is present mainly in dairy products and bovine meat and the amount of these unusual essential fatty acids in animal food depends on seasonal conditions, feeding conditions and rumen microflora. This short review provides an update on in vivo and in vitro studies which demonstrate anticarcinogenic activity of CLA in various animal organs and in different stages of carcinogenesis. These compounds exhibit a protective effect also in atherosclerotic disease at a concentration similar to that found in food. Studies are being carried out to assess the health protecting effect of CLA in humans
Quantifiers
No full textThe chapter focuses on those quantity words that combine with a nominal expression. It distinguishes three main classes: quantifiers proper, quantity adjectives, and semi-lexical quantity nouns. Quantifiers select a full nominal expression (DP) as their complement, which can be either definite or indefinite. Quantifiers like ‘all’ select a definite DP, which can appear separated from the quantifier in so-called ‘floating constructions’. Quantifiers like ‘some’ select an indefinite DP, which can be realised by the quantitative clitic en/ne in Catalan, French, and Italian and can occur with a partitive prepositional phrase. Quantity adjectives do not occur in floating or partitive constructions. Semi-lexical nouns require a determiner and combine with an indefinite DP in pseudo-partitive constructions

Nuove frontiere nella valutazione della qualità degli alimenti
No full textLa globalizzazione del mercato che introduce nuovi prodotti e nuove preparazione gastronomiche provenienti da Paesi quali India, Cina, Sud America, insieme allo sviluppo di avanzate tecniche agronomiche, di allevamento e di conservazione hanno contribuito in maniera determinante all'e¬norme disponibilità e diffusione dei prodotti alimentari sulle nostre tavole, tanto che sono ormai eliminati i vincoli della stagionalità per molti prodot¬ti, specie per gli ortofrutticoli. Nello scenario attuale definire il concetto di qualità degli alimenti (Food Quality, FQ) solo in termini di salubrità e sicurezza igienica non e più suffi¬ciente. La norma UNI EN ISO 8402 definisce la qualità come « l'insieme delle proprietà e caratteristiche di un prodotto o servizio che gli conferiscono l'attitudine a soddisfare bisogni espressi o impliciti». ». La qualità di un prodot¬to alimentare diviene un concetto complesso da definire: si tratta di una no¬zione in parte soggettiva (caratteristiche organolettiche del prodotto), in parte oggettiva (qualità nutrizionali, sicurezza d’uso, proprietà salutistiche fattori psicologici ecc). Sulla base di tutti questi fattori la tendenza attuale e quella di riferirsi alla qualita con un nuovo concetto, ovvero quello della Total Food Quality (TFQ)
Photoacustic techniques applied to non-destructive analysis of phytochemicals in typical foods of the Mediterranean diet
No full textFruits and vegetable have long been regarded as having considerable beneficial effects on health due in part, to the presence of bioactive compounds or phytochemicals. Some of these molecules, such as chlorophylls, carotenoids and anthocyanins are responsible for the organoleptic qualities of fruit and vegetables. In addition, they are implicated in numerous physiological processes of the plants, being produced in response to different types of abiotic and biotic stress. In particular, chlorophylls and carotenoids, widely found in the skins of fruits like apples, are involved in the photosynthesis process, while anthocyanins together with carotenoids, play an important role in protecting the fruits from photo-damage induced by UV irradiation. Thanks to these properties, the mentioned pigments play an important role as biomarkers of nutritional, healthy and commercial quality, so in this respect they receive great interest not only from nutritionists, but also from the agro-food industry.
In apples, chlorophylls, carotenoids and anthocyanins undergo to the changes during ripening and storage of fruits and their direct determination by a non-destructive analytical approach make it possible to correlate the content of these pigments with the degree of ripeness, freshness and shelf life of fruits. Eventually, non-destructive analysis could allow to standardize the quality parameters to meet the needs of both consumers and market.
In recent years, the photoacustic non-destructive technique (PA) have had a great acceleration in food analysis, since is not affected by scattering of light in turbid media, as occur for traditional spectroscopic techniques. Moreover, PA require little or no manipulation of the sample, nor require extraction procedures, so it can be employed for the direct optotermic characterization of the molecules contained in complex matrices such foods.
PA measurement were carried out on the apple peels of two cultivars: Golden Delicious and Royal Gala. The results revealed that PA signals were in agreement with the presence of chlorophylls (a and b), carotenoids and anthocyanins in different side of apple according to the different colour of the portion of apple peel analysed.
The quantitative standardization of the system will allow to correlate the concentration and the proportion of chlorophylls, carotenoids and anthocyanins with ripening state of the fruits in order to provide indication on optimum harvest date of apple fruits
