BIO Bragg gratings on microfibers for label-free biosensing
2021
[EN] Discovering nanoscale phenomena to sense biorecognition events introduces new perspectives to exploit nano science and nanotechnology for bioanalytical purposes. Here we present Bio Bragg Gratings (BBGs), a novel biosensing approach that consists of diffractive structures of protein bioreceptors patterned on the surface of optical waveguides, and tailored to transduce the magnitude of biorecognition assays into the intensity of single peaks in the reflection spectrum. This work addresses the design, fabrication, and optimization of this system by both theoretical and experimental studies to explore the fundamental physicochemical parameters involved. Functional biomolecular gratings ar…
Le preferenze dei consumatori verso i marchi e le etichette di qualità dei prodotti ittici
2022
Il consumo dei prodotti ittici è ormai sempre più analizzato per via delle implicazioni socio-economico-ambientali che da esso ne derivano. Se da un lato un maggiore consumo è sicuramente positivo in termini di salubrità, dall’altro mette in crisi il sistema ambiente per l’eccessivo sfruttamento degli stock ittici. Negli ultimi anni, vi è stata inoltre una progressiva crescita dell’attenzione del consumatore all’impatto ambientale dei processi produttivi con la conseguente maggiore presenza sul mercato di prodotti che utilizzando brand e label associati procedure certificate cercano di aggiungere alla qualità dei prodotti ittici percepita dai consumatori anche componenti che valorizzano pro…

Quantitative Proteome and Phosphoproteome Profiling in Magnaporthe oryzae
2021
The quality and consistency in every sample preparation procedure is crucial for any scientific output. Therefore, it is of utmost importance to have easy, economic, and robust sample preparation protocols. Here, we describe a simple and robust bottom-up proteomic sample preparation strategy for identification and label-free quantification (LFQ) of proteins and phosphoproteins. The presented workflow is designed for large-scale application and involves easy scalable and well-known robust sample preparation techniques, such as cell lysis with SDS buffer under heat, protein precipitation using methanol/chloroform, tryptic digest, and commercially available TiO2 phosphopeptide enrichment kits.…
The hidden side of adverbs
2018
This paper will address the predicative nature of manner adverb(ial)s and of three types of sentence adverbs (subject-oriented, modal, and evaluative) in Italian. Predication often becomes overt by means of morphological correlates. Is it possible to find any such evidence with invariable adverbs? To unveil their predicative nature, a procedure will be suggested in which two sentences, one with a -mente adverb, the other with its cognate adjective (a) share the content morphemes (identity of the signifiant) and (b) entail each other (identity of the signifié as regards semantic roles). A number of such pairs will be discussed, examples of which include: Intelligentemente, Leo intervenne ‘Cl…
(Table 1) Trace element/Ca ratios of Orbulina universa shells from late Neogene Mediterranean samples
2008
A Mediterranean composite sedimentary record was analyzed for Ba/Ca ratios on carbonate shells of Orbulina universa planktonic foraminifer (Ba/Ca)carb providing the opportunity to study and assess the extent of freshwater inputs on the basin and possible impacts on its dynamics during the Tortonian to Recent period. A number of scanning electron microscope analyses and auxiliary trace element measurements (Mn, Sr, and Mg), obtained from the same samples, exclude important diagenetic effects on the studied biogenic carbonates and corroborate the reliability of (Ba/Ca)carb ratios in foraminifera calcite as indicators of seawater source components during the studied interval. A long-term trend…
Stable isotopic composition of three foraminifera species in ODP Hole 160-963D
2020
Carbon-rich layers exist at both sides of the Mediterranean Sea sedimentary record and are called sapropels and organic rich layers (ORLs), respectively in the eastern and western basins. They have different levels of organic carbon accumulation and seafloor oxygen deprivation. The most recent sapropel and ORL deposition have a different timing, 10.8-6.1 and 14.5-9.0 ka respectively. Here we investigate oxygen isotopic records of three foraminifera species that occupy different habitats within the Sicily Channel water column since ~ 12.0 ka, thus in the sill between the eastern and western Mediterranean basins. These data are ice volume-corrected, to get information on water masses density …
