Effect of farming system and cheese making technology on quality traits and fatty acid profile of Caciocavallo Palermitano cheese at different ripeni…
2011
The Caciocavallo Palermitano is a typical stretched curd cheese made from cow milk, mainly in the Western Sicily. The aim of this investigation was to verify the influence of farming system and cheese making process (traditional with wood tools and natural endemic flora vs. innovative with modern stainless steel tools and selected lactic bacteria) on qualitative characteristics, including fatty acid (FA) profile, of Caciocavallo Palermitano at different ripening time. Cheeses were obtained from bulk milk from two farms: one extensive rearing a local breed fed at pasture and one intensive rearing a specialized dairy breed fed mainly hay and concentrate. Milk and cheese properties and FA prof…
Ecology of Vastedda della valle del Belìce cheeses: A review and recent findings to stabilize the traditional production
2018
The increasing request for classic foods has led to a higher demand for cheeses enjoying a “recognition of quality” status. This phenomenon has also affected Sicilian dairy products, in particular protected designation of origin (PDO) “Vastedda della valle del Belìce” (VdB), a cheese traditionally available only during the summer season, but requested year round. The variations of the microbial populations of raw milk among the seasons influence the microbiological quality of the cheeses produced. This review article reports the historical importance of cheeses and the traditional equipment used for dairy productions in Sicily with a specific focus on VdB. The microbial ecology of this chee…
Experimental Evolution Reveals a Genetic Basis for Membrane-Associated Virus Release
2021
Many animal viruses replicate and are released from cells in close association to membranes. However, whether this is a passive process or is controlled by the virus remains poorly understood. Importantly, the genetic basis and evolvability of membrane-associated viral shedding have not been investigated. To address this, we performed a directed evolution experiment using coxsackievirus B3, a model enterovirus, in which we repeatedly selected the free-virion or the fast-sedimenting membrane-associated viral subpopulations. The virus responded to this selection regime by reproducibly fixing a series of mutations that altered the extent of membrane-associated viral shedding, as revealed by fu…
Ultrafast solvent-assisted level crossing in 1-Naphthol
2013
The nonadiabatic inversion dynamics of the energetic order of the electronic excited states of the photoacid 1-naphthol have been revealed by ultrafast spectroscopy on a femtosecond timescale (see picture; IC=internal conversion). The energetic order of the excited states La and Lb of 1-naphthol is reversed in 60 fs in polar dimethyl sulfoxide solvent.
Effects of UV Radiation and Diet on Polyunsaturated Fatty Acids in the Skin, Ocular Tissue and Dorsal Muscle of Atlantic Salmon (Salmo salar) Held in…
2010
Article published in Photochemistry and Photobiology, 86 (4): 909-919 JUL-AUG 2010 The effect of UV radiation (UVR) on juvenile Atlantic salmon (Salmo salar) was assessed by measuring the fatty acid (FA) profiles of muscle, dorsal and ventral skin, and ocular tissues following 4-month long exposures to four different UVR treatments in outdoor rearing tanks. Fish were fed two different diets (Anchovy- and Herring-oil based) that differed in polyunsaturated fatty acid (PUFA) concentrations. Anchovy-fed salmon had higher concentrations of ALA (alpha-linoleic acid; 18:3n-3), EPA (eicosapentaenoic acid; 20:5n-3) and DPA (docosapentaenoic acid, 22:5n-3) in their muscle tissues than fish fed the H…
Características de la práctica físico-deportiva del alumnado con discapacidad de la Universitat de València
2015
En la actualidad, la actividad físico-deportiva es fundamental para las personas con discapacidad debido a los múltiples beneficios físicos, psicológicos y sociales que aporta (Patel y Greydanus, 2010; Slater y Meade, 2004). Estudiar las características de la práctica físico-deportiva de este colectivo puede ser útil para poder desarrollar estrategias y programas que mejoren y aumenten dicha práctica (Bragaru,van Wilgen, Geertzen, Ruijs, Dijsktra y Dekker, 2013). Pese a ello, apenas existen estudios de carácter cuantitativo sobre el tema. De acuerdo con las carencias señaladas, el objetivo de este trabajo es identificar la cuantía de la práctica físico-deportiva del alumnado con discapacida…
Real-world experience with obeticholic acid in patients with primary biliary cholangitis
2021
Background & aims Obeticholic acid (OCA) is the second-line treatment approved for patients with primary biliary cholangitis (PBC) and an inadequate response or intolerance to ursodeoxycholic acid. We aimed to evaluate the effectiveness and safety of OCA under real-world conditions. Methods Patients were recruited into the Italian PBC Registry, a multicentre, observational cohort study that monitors patients with PBC at national level. The primary endpoint was the biochemical response according to Poise criteria; the secondary endpoint was the biochemical response according to normal range criteria, defined as normal levels of bilirubin, alkaline phosphatase (ALP), and alanine aminotransfer…

Main protein component of high density lipoprotein, apolipoprotein A1, modulates leukocyte cell respiration
2015
HDL:n (high density lipoprotein) pääproteiinikomponentin, apolipoproteiini A1:n (ApoA1), on todettu lisäävän glykolyysia ja oksidatiivista fosforylaatiota hiiren luurankolihassoluissa. ApoA1:llä oletetaan myös olevan merkittävä rooli lihaksen normaalissa aineenvaihdunnassa ja siihen liittyvissä sairauksissa. ApoA1 vaikuttaa leukosyyttien aktivaatioon ja jakautumiseen säätelemällä solun sisäistä kolesterolitasoa. Nämä muutokset vaikuttavat myös solun aineenvaihduntaan. ApoA1:n suoranaista vaikutusta leukosyyttien soluhengitykseen ei kuitenkaan ole aiemmin tutkittu. Aiemmin on esitetty, että leukosyyttejä voitaisiin käyttää biomarkkerina kuvaamaan muutoksia mitokondrioiden toiminnassa aineenv…
