Ingegneria energetica ed economia etica

2007

Nell’ambito del paradigma economico “semiotico-ermeneutico e bio-tecnologico”, che afferma una teoria del valore trasversale basata sulla “combinazione creativa dell’energia e dell’informazione”, le valutazioni “economiche” non possono che avere natura multicriteriale e inglobano bilanci di natura termodinamica. I bilanci energetico-entropici devono accompagnare i bilanci puramente economici, per completare e rendere espliciti valori qualitativi non disgiunti dai valori quantitativo-monetari. Il modello valutativo/conoscitivo che viene presentato in questo contributo si situa in questa prospettiva teorico-metodologica. Il modello si basa su valutazioni energetico-entropiche ed economiche al…

Modelling the effect of ethanol on growth rate of food spoilage moulds

2005

The effect of ethanol (E) on the radial growth rate (mu) of food spoilage moulds (Aspergillus candidus, Aspergillus flavus, Aspergillus niger, Cladosporium cladosporioides, Eurotium herbariorum, Mucor circinelloides, Mucor racemosus, Paecilomyces variotii, Penicillium chrysogenum, Penicillium digitatum, Rhizopus oryzae and Trichoderma harzianum) was assessed in Potato Dextrose Agar (PDA) medium at a(w) 0.99, 25 degrees C. In order to model this effect, the Monod type equation described previously by Houtsma et al. (Houtsma, P.C., Kusters, B.J.M., de Wit, J.C., Rombouts, F.M., Zwietering, M.H., 1994.

Data from: Impact of host nutritional status on infection dynamics and parasite virulence in a bird-malaria system

2013

1. Host resources can drive the optimal parasite exploitation strategy by offering a good or a poor environment to pathogens. Hosts living in resource-rich habitats might offer a favourable environment to developing parasites because they provide a wealth of resources. However, hosts living in resource-rich habitats might afford a higher investment into costly immune defences providing an effective barrier against infection. Understanding how parasites can adapt to hosts living in habitats of different quality is a major challenge in the light of the current human-driven environmental changes. 2. We studied the role of nutritional resources as a source of phenotypic variation in host exploi…

CVB3 VP1 interacts with MAT1 to inhibit cell proliferation by interfering with Cdk-activating kinase complex activity in CVB3-induced acute pancreati…

2021

Coxsackievirus B3 (CVB3) belongs to the genus Enterovirus of the family Picornaviridae and can cause acute acinar pancreatitis in adults. However, the molecular mechanisms of pathogenesis underlying CVB3-induced acute pancreatitis have remained unclear. In this study, we discovered that CVB3 capsid protein VP1 inhibited pancreatic cell proliferation and exerted strong cytopathic effects on HPAC cells. Through yeast two-hybrid, co-immunoprecipitation, and confocal microscopy, we show that Menage a trois 1 (MAT1), a subunit of the Cdk-Activating Kinase (CAK) complex involved in cell proliferation and transcription, is a novel interaction protein with CVB3 VP1. Moreover, CVB3 VP1 inhibited MAT…

Single-chain antibodies against a plant viral RNA-dependent RNA polymerase confer virus resistance.

2004

Crop loss due to viral diseases is still a major problem for agriculture today. We present a strategy to achieve virus resistance based on the expression of single-chain Fv fragments (scFvs) against a conserved domain in a plant viral RNA-dependent RNA polymerase (RdRp), a key enzyme in virus replication. The selected scFvs inhibited complementary RNA synthesis of different plant virus RdRps in vitro and virus replication in planta. Moreover, the scFvs also bound to the RdRp of the distantly related hepatitis C virus. T(1) and T(2) progeny of transgenic lines of Nicotiana benthamiana expressing different scFvs either in the cytosol or in the endoplasmic reticulum showed varying degrees of r…

Rosyjskie skrzydlate słowa w polskim dyskursie internetowym

2022

This article is devoted to the functioning of Russian winged words in the Polish Internet discourse. The analysis of the material collected from a variety of websites, blogs, comments, and demotivators showed that Russian winged words are present in the statements of Internet users. In newspaper articles and news programmes, the author or the source of the winged word appears more often, while the authors of blogs and demotivators use Russian units which have lost the link with the source and are easily modifiable. Most often, in the statements of young people there are those that do not require linguistic and cultural competences; they constitute unnamed, permanent expressions for the broa…

Chemical composition and biological activity of the essential oil of Ballota hispanica (L.) Benth. growing wild in Sicily

2015

Ballota L. comprises several relevant species largely used for their excellent therapeutic properties. Ballota hispanica (L.) Benth. is widely used in herbal medicine, and it is sold in herbalist shops for its sedative and antispasmodic properties. Considering its traditional medicinal use and the lack of scientific studies on the volatile components of this species as well as on its biological activities, in this study the chemical composition of the essential oil from aerial parts of B. hispanica, collected in Sicily, was evaluated by gas chromatography and gas chromatography–mass spectrometry. α-Elemol was the most abundant component of the oil (10.9%), followed by α-ylangene (8.5%),…
