Association between dietary folate intake and serum insulin-like growth factor-1 levels in healthy old women

2013

Abstract Objective High serum levels of insulin-like growth factor-1 (IGF-1) seem to coincide with higher rates of some types of cancer and the risk of all-cause mortality in old people. Eating vegetables seems to reduce IGF-1 levels because they are rich in micronutrients such as vitamins. This study investigates the possible association between vitamin intake and IGF-1 levels in a representative group of healthy elderly women with Mediterranean dietary habits. Design This cross-sectional study included 124 healthy women with a mean age of 71.3 ± 4.2 years and a mean body mass index (BMI) of 27.37 ± 3.48 kg/m 2 attending a mild fitness program twice a week at public gyms in Padova. The mai…

Role of poultry meat in a balanced diet aimed at maintaining health and wellbeing: an Italian consensus document

2015

The relationship between the consumption of meat and health is multifaceted, and it needs to be analyzed in detail, with specific attention to the relevant differences that characterize the effects of the different meat types, as yet considered by only a limited literature. A variable but moderate energy content, highly digestible proteins (with low levels of collagen) of good nutritional quality, unsaturated lipids (mainly found in the skin and easily removed), B-group vitamins (mainly thiamin, vitamin B6, and pantothenic acid), and minerals (like iron, zinc, and copper) make poultry meat a valuable food. Epidemiological studies performed across the world, in highly diverse populations wit…

An Analysis of the Presence and Composition of OutLists at United States, Canadian, and European Medical Institutions

2019

Sexual and gender minority (SGM) medical students and physicians are exposed to bias in professional contexts. One strategy for promoting SGM visibility and inclusion within medicine is the development of institutional OutLists, which are online, opt-in lists of SGM-identified individuals affiliated with an academic institution. We present the first quantitative evaluation of publicly accessible OutLists at medical institutions in the United States, Canada, and Europe. Nineteen OutLists were identified in the United States; no OutLists were identified in other countries. All OutLists in the United States were identified at allopathic institutions with no institutional religious affiliation.…

Influence of fruit canopy position and maturity on yield determinants and chemical composition of virgin olive oil

2019

Background While both maturity and light exposure are important factors determining olive fruit physiology, the relationship between maturity, canopy position and optimal harvesting time has not been well-studied. To understand the interaction of these factors, olive fruits from upper and lower layers of the canopy were harvested from September to January. Maturity, moisture and fat content of the fruit as well as the quality and minor components of the oil extracted were measured. Results Lower light interception at the lower canopy positions resulted in differences in the fruits and oil extracted between canopy layers. Upper layer presented 60% of the overall production; fruit had one uni…

Grapevine row orientation mediated temporal and cumulative microclimatic effects on grape berry temperature and composition

2021

Abstract Ambient radiation and temperature are global drivers of grapevine growth, grape yield and composition, and wine quality. Knowledge of the implications of vineyard row orientation/microclimate is required for decision-making in current and future macro- and mesoclimates. Temporal and cumulative microclimatic changes, induced by vine row orientation (NS; EW; NE-SW; NW-SE) of vertically trellised Shiraz grapevines, on berry pulp temperature and composition at different ripeness levels were investigated. Berries dynamically gained heat energy relative to: ambient climate/weather; direct canopy wall/bunch irradiance; and berry skin colour development. Berries exposed to direct solar rad…

EFFECT OF CANOPY MANAGEMENT TECHNIQUES ON THE NUTRITIONAL QUALITY OF MONTEPULCIANO GRAPEVINE IN PUGLIA (SOUTHERN ITALY)

2012

<p style="text-align: justify;"><strong>Aims</strong>: Tests were carried out to assess the effects of early defoliation, cluster thinning and cluster cutting on the basic and nutritional composition of musts and wines of <em>Vitis vinifera</em> L. cv. Montepulciano.</p><p style="text-align: justify;"><strong>Methods and results</strong>: Both production and quality variables of the musts were evaluated. Antioxidant activity was determined on berries and on wines, as were the phenol and anthocyanin concentrations. The wines were compared by sensory evaluation. The results attested to a positive effect of the treatments on grape compositi…

Boundary elements analysis of adhesively bonded piezoelectric active repair

2009

Abstract This paper presents the analysis of active piezoelectric patches for cracked structures by the boundary element method. A two-dimensional boundary integral formulation based on the multidomain technique is used to model cracks and to assemble the multi-layered piezoelectric patches to the host damaged structures. The fracture mechanics behavior of the repaired structures is analyzed for both perfect and imperfect interface between patches and host beams. The imperfect interface, representing the adhesive between two different layers, is modeled by using a “spring model” that involves linear relationships between the interface tractions, in normal and tangential directions, and the …

ANALISI DEL COMPORTAMENTO MECCANICO DI SANDWICHES GREEN COSTITUITI DA PELLI IN BIOCOMPOSITO E CORE IN BALSA/SUGHERO

2022

Negli ultimi anni l’aumento della sensibilità nei confronti della salvaguardia ambientale, anche attraverso apposite norme in materia di lotta all’inquinamento e di riciclo dei materiali a fine vita, ha portato ad un notevole interesse dei ricercatori verso i cosiddetti compositi green, materiali costituiti in genere da rinforzi di origine naturale e matrici “bio-based” a basso impatto ambientale. Una categoria interessante di materiali innovativi, caratterizzati da una elevata resistenza a flessione unita ad un basso peso specifico, è rappresentata dai cosiddetti sandwiches, costituiti in genere da robuste pelli in composito fibro-rinforzato e da un core in materiale molto leggero e poco r…

ANALISI E SVILUPPO DI UN SETUP SPERIMENTALE PER LA DETERMINAZIONE DELLA TENACITÀ A FRATTURA A MODO II NEI MATERIALI COMPOSITI E IBRIDI

Il presente lavoro di Tesi si propone a compimento del percorso previsto dal Ciclo XXVI del corso di Dottorato di Ricerca in Ingegneria Civile e Ambientale – Indirizzo Materiali – seguito durante il triennio Gennaio 2013- Dicembre 2015 presso l’Università degli Studi di Palermo. L’elaborato si sviluppa in due principali sezioni. Dopo un’introduzione all’argomento affrontato, nella prima parte del lavoro, viene analizzato, sia sperimentalmente che numericamente, un setup tipicamente utilizzato nell’industria aeronautica per la caratterizzazione delle delaminazione a MODO II nei materiali compositi (Transverse Crack Tensile test – TCT-test). A partire dai risultati ottenuti dalle analisi prel…

POMOLOGICAL TRAITS, SENSORY CHARACTERISTICS, AND ANTIOXIDANT ACTIVITY IN FRUITS OF NINE LOQUAT CULTIVARS GROWN IN SICILY

2015

Loquat cultivation in Italy currently aims at offering a wider choice of cultivars to growers. The present study determined commercial quality, characterized the antioxidant capacity, and quantified the major bioactive compounds of some local ('BRT 20', 'Claudia', 'Nespolone di Trabia', 'Sanfilippara') and international ('Algerie', 'El Buenet', 'Bueno', 'Golden Nugget' and 'Peluche') cultivars. Fruit was harvested at commercial ripening and chemical-physical determinations of weight, diameters, skin and flesh color, soluble solid content, tritable acidity, antioxidant activity and polyphenol content, and sensory analyses were carried out. Data showed a large variability among genotypes and …
