Foods , 2013, DOI: 10.3390/foods2010053
Abstract: Cereal foods are a fundamental part of a balanced diet and several studies have assigned to wholemeal cereal products a protective role in human health, due to their content of bioactive compounds. Within the phytochemicals, lignans are of increasing interest for their potential anticarcinogenic, antioxidant, estrogenic and antiestrogenic activities. The aim of this work is to contribute to the updating of food lignan databases by providing the profile and the amount of lignans in cereals, buckwheat and several cereal based foods commonly consumed in human diets. Values were taken from published papers. Items were divided in different groups, namely grains, brans and flours, bread, cereal staple foods, breakfast cereals and other cereal products, and values for secoisolariciresinol, matairesinol, pinoresinol, lariciresinol are given. For example, the total average values for the mentioned lignans in grains ranged between 23 μg/100 g and 401 μg/100 g dry weight. The contribution of each single lignan molecule to the total value of lignans appears to be different for every cereal species. Lignan content and typology in processed foods depends on the raw materials used, their degree of refinement and on processing conditions.

Agriculture , 2013, DOI: 10.3390/agriculture3020285
Abstract: Wild rocket [ Diplotaxis tenuifolia (L.) DC.] belongs to the Brassicaceae family and has its origin in the Mediterranean region. The effect of conventional and integrated cultivation practices on the nutritional properties and benefits of wild rocket [ Diplotaxis tenuifolia (L.) DC.] were studied. Bioactive molecules content (vitamin C, quercetin, lutein), antioxidant properties and bioactivity of polyphenolic extracts from the edible part of rocket in Caco-2 cells were determined. Regarding antioxidant properties, FRAP (Ferric Reducing Antioxidant Power) values ranged from 4.44 ± 0.11 mmol/kg fw to 9.92 ± 0.46 mmol/kg fw for conventional rocket and from 4.13 ± 0.17 fw mmol/kg to 11.02 ± 0.45 mmol/kg fw for integrated rocket. The characteristics of wild rocket as a dietary source of antioxidants have been pointed out. Significant differences in the quality of conventional and integrated rocket have been shown, while no influence of agronomic practice on biological activity was reported. A significant accumulation of cells in G1 phase and a consequent reduction in the S and G2 + M phases were observed in Caco-2 cells treated with rocket polyphenol extract.

Antioxidants , 2013, DOI: 10.3390/antiox2020052
Abstract: The artichoke ( Cynara cardunculus L. subsp. scolymus L.), the cultivated cardoon ( Cynara cardunculus var. altilis DC.) and the wild cardoon ( Cynara cardunculus var. sylvestris L.) are species widely distributed in the Mediterranean area. The aim of this research was to evaluate the antioxidant properties of seeds from lines of artichoke and cultivated and wild cardoon in both aqueous-organic extracts and their residues by FRAP (Ferric Reducing Antioxidant Power) and TEAC (Trolox Equivalent Antioxidant Capacity) evaluations. Both artichoke and cardoon seeds are a good source of antioxidants. Among artichoke seeds, hydrolysable polyphenols contribution to antioxidant properties ranged from 41% to 78% for FRAP values and from 17% to 37% for TEAC values. No difference between cultivated and wild cardoon in antioxidant properties are reported. Our results could provide information about the potential industrial use and application of artichoke and/or cardoon seeds.
The Concept of “Persecution” in Refugee Law: Indeterminacy, Context-sensitivity, and the Quest for a Principled Approach
Francesco Maiani
Les Dossiers du Grihl , 2010, DOI: 10.4000/dossiersgrihl.3896
Abstract: IntroductionIn explaining to us the object and purpose of this workshop, Jean-Pierre Cavaillé has posited that the notion of persecution suffers from a “woeful lack of definition”. If this were unconditionally true, then international refugee law would be in jeopardy.It would be in jeopardy, because the concept of “persecution” is central to the universal refugee definition laid down by the 1951 Geneva Convention (GC). Indeed, Article 1A GC defines the refugee as someone who has a well-founde...
Nicola Cabibbo, Physicist and Science Manager*
Maiani L.
EPJ Web of Conferences , 2012, DOI: 10.1051/epjconf/20122400002
Abstract: Universality of the weak interactions is reviewed, with special emphasis on the origin of the Cabibbo theory of strange-particle β-decays and its role in the discovery of the unified Electroweak Theory. Achievements and present challenges of the Standard Theory of particles interactions are briefly illustrated. As a homage to Nicola Cabibbo, his leading role in the Roma school of theoretical physics and in the Italian science in general is reviewed.

Nutrition Journal , 2011, DOI: 10.1186/1475-2891-10-125
Abstract: An observational study was conducted on 131 healthy free-living subjects. Dietary intake was assessed by dietary diary. Standardised procedures were used to make anthropometric measurements. On blood samples (serum, plasma and whole blood) were evaluated: antioxidant status by vitamin A, vitamin E, carotenoids, vitamin C, uric acid, SH groups, SOD and GPx activities; lipid blood profile by total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides; total antioxidant capacity by FRAP and TRAP; the immune status by TNF-α, and IL-10 cytokines; the levels of malondialdehyde in the erythrocytes as marker of lipid peroxidation.The daily macronutrients intake (g/day) have shown a high lipids consumption and significant differences between the sexes with regard to daily micronutrients intake. On total sample mean Mediterranean Diet Score (MDS) was 4.5 ± 1.6 and no significant differences between the sexes were present. A greater adherence to a Mediterranean dietary pattern increases the circulating plasma levels of carotenoids (lutein plus zeaxanthin, cryptoxanthin, α and β-carotene), vitamin A and vitamin E. The levels of endogenous antioxidants were also improved. We observed higher levels in anti-inflammatory effect cytokines (IL-10) in subjects with MDS ≥ 6, by contrast, subjects with MDS ≤ 3 show higher levels in sense of proinflammatory (TNF α P < 0.05). Lower levels of MDA were associated with MDS > 4. Our data suggest a protective role of vitamin A against chronic inflammatory conditions especially in subjects with the highest adherence to the Mediterranean-type dietary pattern.Mediterranean dietary pattern is associated with significant amelioration of multiple risk factors, including a better cardiovascular risk profile, reduced oxidative stress and modulation of inflammation.The Mediterranean Diet (MD), a nutritional model inspired by the traditional food regimes of countries in the Mediterranean basin, including Italy, Greece, Spain and Morocco, has ente
Unstable Systems in Relativistic Quantum Field Theory
L. Maiani,M. Testa
Physics , 1997, DOI: 10.1006/aphy.1997.5762
Abstract: We show how the state of an unstable particle can be defined in terms of stable asymptotic states. This general definition is used to discuss and to solve some old problems connected with the short-time and large-time behaviour of the non-decay amplitude.
Causality in Local Quantum Field Theory
L. Maiani,M. Testa
Physics , 1994, DOI: 10.1016/0370-2693(95)00800-Z
Abstract: The problem of causality is analyzed in the context of Local Quantum Field Theory. Contrary to recent claims, it is shown that apparent noncausal behaviour is due to a lack of the notion of sharp localizability for a relativistic quantum system. (Replaced corrupted file)
