Genetic polymorphism at the CSN1S1 gene in Girgentana dairy goat breed
2013
The aim of this work was to evaluate the variability of the αs1-casein locus in the endangered Girgentana dairy goat breed in order to define genetic improvement and a conservation program for this breed. The study was performed on 200 dairy goats by means of different PCR protocols. The most frequent alleles were A (0.590) and F (0.290) followed by B (0.065) and N (0.047). CSN1S1 E allele was identified with a very low frequency (0.008). The most common genotype was AF (0.365) followed by AA (0.340). The high frequency of the strong genotypes is associated with the production of milk with high fat and protein content and with optimal technological properties. In Girgentana goat breed, the …
Application of microsatellite markers as potential tools for traceability of Girgentana goat breed dairy products
2015
In livestock, breed assignment may play a key role in the certification of products linked to specific breeds. Traceability of farm animals and authentication of their products can contribute to improve breed profitability and sustainability of animal productions with significant impact on the rural economy of particular geographic areas and on breed and biodiversity conservation. With the goal of developing a breed genetic traceability system for Girgentana dairy products, the aim of this study was to identify specific microsatellite markers able to discriminate among the most important Sicilian dairy goat breeds, in order to detect possible adulteration in Girgentana dairy products. A tot…
July 2003: 62-year-old female with progressive muscular weakness
2004
The July 2003 Case of the Month (COM). A 62-year-old female patient experienced progressive muscular weakness over the last ten years, involving shoulder and pelvic girdle muscles, paraspinal and facial muscles. A biopsy was taken from the left deltoid muscle where hepatitis vaccination had taken place 4 weeks previously. The specimen revealed macrophagic myofasciitis due to the injection of aluminium-bound vaccines. The finding can be reproduced experimentally by injecting vaccines in rats. The pathomechanism is supposed to involve immune stimulation due to long term persistence of the adjuvant. Macrophagic myofasciitis has been suggested to occasionally cause myopathy but is supposed to b…
Entre moneo e memini. Arquitectura funeraria militar en el sureste de Sicilia.
2023
Nel luglio del 1943 la costa sud-orientale della Sicilia fu teatro dello sbarco attuato dalle forze militari Alleate da cui prende avvio la liberazione dal nazi-fascismo dell’Italia e dell’Europa. Gli eventi bellici siciliani furono inevitabilmente piuttosto cruenti e videro un numero elevato di morti di soldati italiani, tedeschi e dei militari delle forze anglo-americane. Sin dagli anni Cinquanta del ’900, la Commonwealth War Grave Commission e la Volksbund, al fine di onorare i militari Alleati e tedeschi caduti in battaglia, avviarono la realizzazione di diversi cimiteri di guerra tra Agira, Catania, Siracusa e Motta Sant’Anastasia. I primi tre, progettati da Louis de Soissons, destinat…
Symplectic analysis of thin-walled curved box girders with torsion, distortion and shear lag warping effects
2022
Shear lag effect and torsional and distortional warping can significantly affect the performance of thin-walled curved box girders used in modern bridge engineering. The structural behaviour of these bridges exhibits complexity due to coupled bending and torsion together with warping effects of non-uniform torsion, distortion and shear lag. A practical method of analysis, based on the symplectic approach, with the same perspective as the Higher Order Beam Theories, is presented for overcoming the difficulties of numerical approaches via the Finite Element Method. In this paper, the Hamiltonian Structural Analysis method implements the analysis of the shear lag effect together with non-unifo…
Analysis of non-uniform torsion in curved incrementally launched bridges
2014
Abstract Incremental launching is a common and convenient methodology to build continuous girder bridges on several piers. Although it has mainly been applied to straight bridges with box sections, today it is also used for construction of horizontally curved bridges with concrete and composite steel–concrete closed or open sections like I-girders. In these cases the contribution of torsion to the stress state becomes of primary importance when the construction stages of these bridges are analysed. Moreover, the presence of thin-walled cross-sections, makes the analysis of non-uniform torsion fundamental when the angle of twist per unit length is not constant or warping is prevented in thos…
Effects of school-based interventions on motivation towards physical activity in children and adolescents: A systematic review and meta-analysis
2020
Introduction Assuming that motivation is the key to initiate and sustain beneficial health behaviors, the aim of this systematic review was to analyze the effects of school-based physical activity interventions on a variety of motivational outcomes towards PA in school-aged children and adolescents. Methods A comprehensive literature search was carried out in six electronic databases to identify randomized controlled trials and quasi-experimental trials examining the effects of PA interventions implemented during the regular school day, e.g., during physical education lessons or lunch breaks. Primary outcomes of interest were students' motivation, basic psychological needs, goal orientation…
CARTOGRAPHY OF AGROCLIMATIC INDICES AT MESOSCALE LEVEL: METHODOLOGY AND CASE STUDY OF BORDEAUX WINEGROWING AREA. Implications on vine development and…
2007
Climate spatial variability knowledge is essential in agronomy and forestry, in order to characterize production potential or to assess pest development risks. In viticulture, climate mainly governs grapevine development rate and berry ripening. The aim of the present work is to characterise climate spatial variability at mesoscale level, using several spatialization techniques at daily time step, applied to climate variables and agroclimatic indices, in order to evaluate its consequences on grapevine development and grape ripening. This study was led in the Bordeaux winegrowing region. Six variables were studied: minimum and maximum temperatures, solar radiation, reference evapotranspirati…
Dissolved silica in the Garonne River waters : changes in the weathering dynamics
2000
The major ion chemistry of the Garonne River is indicative of seasonal variations in the weathering dynamics of the drainage basin. Using the geochemical model MEGA for calculation of the contribution of atmospheric CO2 to the total bicarbonate fluxes exported by the Garonne River allows estimations of the concentrations of the major dissolved elements that originate from silicate- and carbonate-rock weathering. The molecular ratio SiO2/Al2O3 was calculated for the 1989–1992 period to identify the main type of weathering in the Garonne River, and montmorillonite was shown to be the major mineral occurring in the weathering products. The seasonal variations of the SiO2/Al2O3 ratio also showe…
