Virus-cell interactions as a pathological mechanism of parvovirus infection

2014

Inferring Phytoplankton, Terrestrial Plant and Bacteria Bulk δ¹³C Values from Compound Specific Analyses of Lipids and Fatty Acids.

2015

Stable isotope mixing models in aquatic ecology require δ13C values for food web end members such as phytoplankton and bacteria, however it is rarely possible to measure these directly. Hence there is a critical need for improved methods for estimating the δ13C ratios of phytoplankton, bacteria and terrestrial detritus from within mixed seston. We determined the δ13C values of lipids, phospholipids and biomarker fatty acids and used these to calculate isotopic differences compared to the whole-cell δ13C values for eight phytoplankton classes, five bacterial taxa, and three types of terrestrial organic matter (two trees and one grass). The lipid content was higher amongst the phytoplankton (…

From soil to soil-less in horticulture: quality and typicity

2013

In this review, the technique of soil-less cultivation of horticultural crops is analysed, the main differences between this and traditional cultivation techniques are described, and the advantages and disadvantages of each method in relation to the others are identified. Soilless cultivation has revolutionised various sectors of vegetable and floriculture production, and recent years have also seen interest being shown by Italian fruit crop producers, particularly those involved in table grape viticulture. The various issues related to the use of this technique are described in relation to the needs of the substrate, water management, and mineral nutrition of the different species, and to …

Revegetation through hydroseeding in degraded Mediterranean areas

2012

Hydroseeding is a technique increasingly used to establish vegetation on degraded areas in order to perform environmental protection. The objective of this paper was to evaluate the effectiveness of four different hydroseeding methods on a degraded artificial slope in the southern Mediterranean area determining total vegetation cover, hydroseeding vegetation cover, hydroseeding success index (HSI), natural and hydroseeded vegetation height. The test area does not allow the use of any operating machine for soil and vegetation management, the only applicable technique is therefore hydroseeding. After hydroseeding was applied (December 2010), 21 checks were carried out every 15 days (from Janu…

Dry stone buildings in Sicily. An environmental and territorial resource

2013

Dry stone constructions are widespread throughout many regions across the world, in a wide variety of forms, according to the environmental and socio-economic contexts, and constitute a valuable know-how which is today in danger of disappearing. In Sicily dry stone works have traditionally been used in the area of Val di Noto where they constitute a key character of the landscape, and in the Madonie Mounts in which some policies of enhancement have been recently initiated. In the framework of the Grundtvig programme “La préservation du patrimoine architectural bâti en pierre sèche”, an in-depth analysis of these architectures have been pursued, aiming to create a database inventory. This pa…

Stakeholder perceptions of wood-based products in the built environment : a literature review

2022

Current global environmental challenges, such as climate change, set an urge to seek renewable low-emission alternatives to substitute fossil fuel-derived products while transitioning towards circular bioeconomy. Wood has proven to be a versatile renewable material that is able to substitute fossil-based materials. However, the market potential and uptake of wood-based products is also dependent on the preferences of consumers and other stakeholder groups. This paper presents a systematic literature review of studies examining stakeholder perceptions of wood-based products, which also resulted in the identification of research gaps and suggestions for future research directions. The results…

Single amino acid substitutions in the glycoprotein B carboxy terminus influence the fusion from without property of herpes simplex virus type 1.

1995

Syncytial mutations of herpes simplex virus type 1 (HSV-1) strains ANG, ANG path, HFEM, tsB5 and HSZP cause extensive cell fusion and were mapped to the cytoplasmic domain of glycoprotein B (gB), within the syn 3 locus. These strains are so far the only ones which show the phenotype ‘fusion from without’ (FFWO): 60 min after infection with high m.o.i., cells in a tissue culture are fused without transcription and translation of the viral genome. In this report we detected, using the recombinants 27/III and K-7, that an amino acid exchange from Ala to Val at aa position 854 of gB is the main determinant for FFWO activity of strains ANG, ANG path and recombinant K-7. The transfer of this muta…

A single tube PCR assay for detecting viruses and their recombinants that cause tomato yellow leaf curl disease in Mediterranean basin

2007

Tomato yellow leaf curl disease (TYLCD) is well known in Mediterranean countries, where it has been causing severe losses in tomato crops for decades. Until recently, two viruses (with several isolates) in the genus Begomovirus, family Geminiviridae, have been associated with the epidemics: Tomato yellow leaf curl virus (TYLCV) and Tomato yellow leaf curl Sardinia virus (TYLCSV). However, recombinants between these, such as Tomato yellow leaf curl Malaga virus (TYLCMalV), are spreading, and new methods for detecting all viruses present in the region are needed. By considering all DNA sequences available of viruses causing TYLCD in the Mediterranean basin, a PCR/RFLP protocol was developed t…

Il difficile bilanciamento tra tutela della madre vulnerabile, best interest del minore e diritti culturali della donna migrante al vaglio della Cort…

2021

Il contributo offre il commento di una recente della Corte Europea dei Diritti dell’Uomo riguardante un caso di violazione del diritto alla vita privata e familiare, di cui all’art. 8 della Convenzione Europea dei Diritti dell’Uomo, da parte della Repubblica Italiana. L’autrice ricostruisce i principali fatti che caratterizzano il caso concreto e le questioni di diritto sottoposte all’attenzione della Corte, analizzando la sentenza in commento sulla base di due essenziali nodi logico-argomenta- tivi: il primo riguarda il difficile contemperamento tra i valori protetti dalla normativa in materia di adozione e il diritto di genitori e figli a mantenere in vita, per quanto compatibile con il b…

Regional Farmers’ Perception and Societal Issues in Vineyards Affected by High Erosion Rates

2021

We explore the current situation in a viticultural region in Eastern Spain from a holistic and multifaceted research approach, which allowed us to understand the biophysical conditions, economic cost, social impact, and perception of the farmers’ community to the use of catch crops. A survey of the perception of the farmers, and an assessment of the biophysical impact of catch crops (CC) and tillage (C = Control plot) on soil organic matter, bulk density, infiltration capacity (single ring infiltrometer), and runoff generation and soil erosion (rainfall simulation experiments) was carried out. Two representative fields as study sites were selected in Les Alcusses valley, within Els Alforins…
