Behavior of the total antioxidant status in a group of subjects with metabolic syndrome.
2014
AIM: Our purpose was to examine the total antioxidant status (TAS) in subjects with metabolic syndrome (MS) subdivided according to the presence or not of diabetes mellitus. METHODS: We enrolled 106 subjects (45 women, 61 men) with MS subsequently subdivided in diabetics (14 women, 29 men) and nondiabetics (31 women, 29 men). TAS was obtained using an Assay kit which relies on the ability of plasma antioxidant substances to inhibit the oxidation of 2,2'-azino-bis(3-ethylbenzthiazoline sulfonic acid) to the radical ABTS+. RESULTS: In the group of MS subjects a significant decrease in TAS (p<0.05) in comparison with normal controls was evident. This difference was present between normal subje…

Relationship between elastase and total antioxidant status in young subjects with recent myocardial infarction
2008
In a group of young subjects with acute myocardial infarction (AMI) (68 men and 7 women; mean age 39.6 ± 5.7 years) we examined the plasma concentration of elastase, the thiobarbituric acid-reactive substances (TBARS) and the total antioxidant status (TAS) at the initial stage of AMI. In this group we found an increase of elastase (p <0.001) and TBARS (p < 0.001) and a decrease of TAS (p < 0.001). A statistical correlation was observed in the whole group of AMI patients between plasma elastase and TAS (p < 0.01) and this correlation was more statistically significant in patients with more risk factors and not in those with more involved vessels.
Effects of extra-virgin olive oil enriched with E-vitamin and Q10-coenzyme on the heart rate variability and plasma antioxidant status in athletes
2010
OBJECTIVES: To examine whether the assumption of extra virgin olive oil enriched with E-vitamin and Q10-coenzyme may improve the plasma anti-oxidant/pro-oxidant balance and be associated with favorable changes in heart rate variability (HRV). METHODS: Four male athletes, mean age 22 (range 21-24), were recruited. They assumed 20 ml per day of the integrator (20 mg Q10 and 15 mg Vit E) for one month. The plasma antioxidant capacity (AC) was evaluated by the crocin bleaching assay. The frequency-domain analysis of HRV was carried out using Cardioline Cube recorder and specific software to obtain, from an autoregressive power spectrum approach, the power in normalized units (nu) of the low-(LF…
Uso di estratti antiossidanti di crusca di grano duro per ottenere una nuova pasta funzionale con l’approccio di arricchimento “da grano a grano”
2017
La crescente attenzione dei consumatori per gli alimenti funzionali ha stimolato le ricerche su nuovi tipi di pasta ottenuti con ingredienti in grado di migliorarne l’attività antiossidante, il profilo amminoacidico o il contenuto di acidi grassi polinsaturi e fibre, con risultati, però, non sempre soddisfacenti a causa di alterazioni delle proprietà tecnologiche e sensoriali della pasta (consistenza, tenuta alla cottura, odori e sapori inusuali). La crusca di grano duro contiene numerosi composti bioattivi, tra cui fenoli, carotenoidi e tococromanoli, che possono essere estratti con tecnologie green e reintegrati nell’impasto per ottenere prodotti con caratteristiche simili alla pasta trad…
Raman Spectroscopy Technology to Monitor the Carotenoids in Skin of Thalassemia Patients: A Novel Non-Invasive Tool Relating Oxidative Stress with Ir…
2014
In this work we approach the relationship between redox state and iron overload by noninvasive instrumental techniques. Intracardiac, liver iron and liver fibrosis have been monitored in transfusion-dependent thalassemia patients by magnetic resonance imaging and hepatic transient elastography examinations. These measurements have been matched with a non-invasive, and yet unexplored in clinical practice, evaluation of body’s oxidative stress through measurement of antioxidant carotenoids in skin, by a spectroscopic method based on Raman technology (RRS). The global body’s antioxidant status results from a balance between the level of antioxidants in cells and body fluids, including blood, a…
