IL VALORE PERCEPITO DAL TURISTA NELL’ESPERIENZA AGRITURISTICA: COSTRUZIONE DI UN INDICATORE SINTETICO

Antioxidant status and circulating lipids are altered in human gestational diabetes and macrosomia.

2007

Fetuses from mothers with gestational diabetes are at increased risk of developing neonatal macrosomia and oxidative stress. We investigated the modulation of antioxidant status and circulating lipids in gestational diabetic mothers and their macrosomic babies and in healthy age-matched pregnant women and their newborns. The serum antioxidant status was assessed by employing anti-radical resistance kit (KRL; Kirial International SA, Couternon, France) and determining levels of vitamin A, C, and E and the activity of superoxide dismutase (SOD). Circulating serum lipids were quantified, and lipid peroxidation was measured as the concentrations of serum thiobarbituric acid-reactive substances …

A Comprehensive Review on Lipid Oxidation in Meat and Meat Products.

2019

Meat and meat products are a fundamental part of the human diet. The protein and vitamin content, as well as essential fatty acids, gives them an appropriate composition to complete the nutritional requirements. However, meat constituents are susceptible to degradation processes. Among them, the most important, after microbial deterioration, are oxidative processes, which affect lipids, pigments, proteins and vitamins. During these reactions a sensory degradation of the product occurs, causing consumer rejection. In addition, there is a nutritional loss that leads to the formation of toxic substances, so the control of oxidative processes is of vital importance for the meat industry. Noneth…

N-3 fatty acids modulate antioxidant status in diabetic rats and their macrosomic offspring.

2006

We investigated the role of dietary n-3 polyunsaturated fatty acids (n-3 PUFA) in the modulation of total antioxidant status in streptozotocin (STZ)-induced diabetic rats and their macrosomic offspring. Female wistar rats, fed on control diet or n-3 PUFA diet, were rendered diabetic by administration of five mild doses of STZ on day 5 and were killed on days 12 and 21 of gestation. The macrosomic (MAC) pups were killed at the age of 60 and 90 days. Lipid peroxidation was measured as the concentrations of plasma thiobarbituric acid reactive substances (TBARS), and the total antioxidant status was determined by measuring (i) plasma oxygen radical absorbance capacity (ORAC), (ii) plasma vitami…

Combined effect of natural antioxidants and antimicrobial compounds during refrigerated storage of nitrite-free frankfurter-type sausage.

2019

Abstract The effects of nisin (200 and 400 ppm), e-polylysine (0.1 and 0.2%) and chitosan (0.5 and 1%) in combination with a Mixed Extract (green tea, stinging nettle and olive leaves extracts) on the physicochemical, microbiological characteristics, fatty acid composition and sensory attributes of the nitrite-free frankfurter-type sausages were assessed during 45 days of storage. The results revealed no significant differences on moisture, fat, protein, ash, salt and water activity (aw) among treatments. 1% Chitosan + Mixed Extract sausages displayed the lowest thiobarbituric acid reactive substances (TBARS) and total volatile nitrogen (TVN) values compared to Control after 45 days of refr…

Skriftliga språkkunskaper i A-svenska hos finska abiturienter på basis av processbarhetsteori

2016

Tämän tutkimuksen tarkoituksena oli tutkia suomenkielisten, ruotsin kielen pitkää oppimäärää opiskelevien abiturienttien kirjallista kielitaitoa lukio-opintojen loppuvaiheessa. Tutkimushenkilöt (n=12) olivat aloittaneet ruotsin kielen opiskelun alakoulun 3.–5. vuosiluokalla ja valmistautuivat tutkimushetkellä ruotsin kielen pitkän oppimäärän ylioppilaskirjoituksiin. Tutkimuksen pohjana käytettiin Pienemannin prosessoitavuusteoriaa (1998). Tutkittavat kieliopilliset rakenteet olivat inversio väitelauseessa, jälkilauseen sanajärjestys, kieltosanan paikka sivulauseessa, epäsuora kysymys sekä adjektiivi attributiivisena ja predikatiivisena lauseenjäsenenä. Tutkimuksen tulokset osoittavat, että …

"Sit mä tajusin, et tonne mä haen" : abiturienttien käsityksiä ammatin- ja koulutusvalinnasta sekä ammatinvalinnanohjauksesta lukiossa

2011

Ammatin- ja koulutusvalintaprosessi on nuorille ajankohtainen asia ensimmäisen kerran jo peruskoulun lopun lähestyessä. Lukion valinneet taas joutuvat pohtimaan ammatinvalinta-asioita perusteellisesti jopa ensimmäiseltä vuosikurssilta lähtien. Nykyään nuorilla on todella paljon vaihtoehtoja ja mahdollisuuksia siihen, mitä he voivat tehdä lukion jälkeen. Halusimmekin tutkia, kuinka abiturientit kokevat tämän elämänvaiheen ja mahdollisuuksien paljouden. Tämän pro gradu -työn tarkoituksena oli selvittää abiturienttien ammatin- ja koulutusvalinnallisia käsityksiä, suunnitelmia ja varmuutta. Selvitimme, mitkä ovat abiturienttien käsityksien mukaan merkittäviä asioita ammatin- ja koulutusvalinnas…

Chiral hemicucurbit[8]uril as an anion receptor: selectivity to size, shape and charge distribution

2017

A novel eight-membered macrocycle of the hemicucurbit[n]uril family, chiral (all-R)-cyclohexanohemicucurbit[8]uril (cycHC[8]) binds anions in a purely protic solvent with remarkable selectivity. The cycHC[8] portals open and close to fully encapsulate anions in a 1 : 1 ratio, resembling a molecular Pac-Man™. Comprehensive gas, solution and solid phase studies prove that the binding is governed by the size, shape and charge distribution of the bound anion. Gas phase studies show an order of SbF6− ≈ PF6− > ReO4− > ClO4− > SCN− > BF4− > HSO4− > CF3SO3− for anion complexation strength. An extensive crystallographic study reveals the preferred orientations of the anions within the octahedral cav…
