Diversity Assessment and DNA-Based Fingerprinting of Sicilian Hazelnut (Corylus avellana L.) Germplasm
2022
The characterization of plant genetic resources is a precondition for genetic improvement and germplasm management. The increasing use of molecular markers for DNA-based genotype signature is crucial for variety identification and traceability in the food supply chain. We collected 75 Sicilian hazelnut accessions from private and public field collections, including widely grown varieties from the Nebrodi Mountains in north east Sicily (Italy). The germplasm was fingerprinted through nine standardized microsatellites (SSR) for hazelnut identification to evaluate the genetic diversity of the collected accessions, validating SSR discrimination power. We identified cases of homonymy and synonym…
Development-dependent changes in the tight DNA-protein complexes of barley on chromosome and gene level
2008
Abstract Background The tightly bound to DNA proteins (TBPs) is a protein group that remains attached to DNA with covalent or non-covalent bonds after its deproteinisation. The functional role of this group is as yet not completely understood. The main goal of this study was to evaluate tissue specific changes in the TBP distribution in barley genes and chromosomes in different phases of shoot and seed development. We have: 1. investigated the TBP distribution along Amy32b and Bmy1 genes encoding low pI α-amylase A and endosperm specific β-amylase correspondingly using oligonucleotide DNA arrays; 2. characterized the polypeptide spectrum of TBP and proteins with affinity to TBP-associated D…
Upes nēģa Lampetra fluviatilis populāciju ģenētiskās daudzveidības izpēte ar mikrosatelītiem
2020
Šis bakalaura darbs ir turpinājums kursa darbam - “Kurzemes upēs sastopamo upes nēģu Lampetra fluviatilis mikrosatelītu genotipēšana”. Šis ir pirmais pētījums Latvijā par upes nēģa ģenētisko daudzveidību un populācijas ģenētisko struktūru Latvijas upēs, pamatojoties uz mikrosatelītu DNS variācijām. Darba mērķis bija novērtēt upes nēģa populācijas ģenētisko daudzveidību Latvijā. Iegūtie dati veicinās zināšanas par upes nēģu ģenētisko struktūru un palīdzēs izstrādāt ieteikumus ģenētisko resursu ilgtspējīgai apsaimniekošanai. No piecām upēm (Saka, Venta, Daugava, Salaca, Gauja) kopā tika ievākti 210 upes nēģa audu paraugi no muguras spurām, no kuriem tika izdalīta DNS. Genotipēšana tika veikta…
RENATO DE FUSCO e RAFFAELLA ROSA RUSCIANO, Design e Mezzogiorno tra storia e metafora, Progedit, Bari 2015
2016
Comunemente si pensa che il Mezzogiorno sia un luogo sospeso nel tempo, la cui cultura millenaria s’è per così dire cristallizzata, incapace di evolversi, da secoli, incastonata in un magnifico paesaggio che trae la sua bellezza da fortunate condizioni geoclimatiche. Perciò il titolo del recente saggio di De Fusco e Rusciano – Design e Mezzogiorno – deve apparire inizialmente ossimorico: il design come simbolo della modernità del Nord e il Mezzogiorno come simbolo del sottosviluppo del Sud d’Italia. I tempi di Federico II appartengono ai libri di storia, la stupefacente architettura arabo-normanna, il magnifico edificio della Zisa, capolavoro di fisica tecnica… sono ormai residui di una glo…
Determination of N-nitrosodiethanolamine in cosmetic products by reversed-phase dispersive liquid-liquid microextraction followed by liquid chromatog…
2016
A new analytical method for the determination of N-nitrosodiethanolamine (NDELA), a very harmful compound not allowed in cosmetic products, is presented. The method is based on a new approach of dispersive liquid-liquid microextraction (DLLME) useful for extraction of highly polar compounds, called reversed-phase DLLME (RP-DLLME), followed by liquid chromatography-ultraviolet/visible (LC-UV/Vis) determination. The variables involved in the RP-DLLME process were studied to provide the best enrichment factors. Under the optimized conditions, a mixture of 750µL of acetone (disperser solvent) and 125µL of water (extraction solvent) was rapidly injected into 5mL of toluene sample solution. The e…
Determination of N -nitrosamines in cosmetic products by vortex-assisted reversed-phase dispersive liquid-liquid microextraction and liquid chromatog…
2018
A new analytical method for the simultaneous determination of trace levels of seven prohibited N-nitrosamines (N-nitrosodimethylamine, N-nitrosoethylmethylamine, N-nitrosopyrrolidine, N-nitrosodiethylamine, N-nitrosopiperidine, N-nitrosomorpholine, and N-nitrosodiethanolamine) in cosmetic products has been developed. The method is based on vortex-assisted reversed-phase dispersive liquid-liquid microextraction, which allows the extraction of highly polar compounds, followed by liquid chromatography with mass spectrometry. The variables involved in the extraction process were studied to obtain the highest enrichment factor. Under the selected conditions, 75 μL of water as extraction solvent …

Comparison of single-spot technique and RGB imaging for erythema index estimation
2016
A commercially available point measurement device, the Mexameter(®), and an experimental RGB imaging prototype device were used for erythema index estimation of 50 rosacea patients by analysing the level of skin redness on the forehead, both cheeks and both sides of a nose. Results are compared with Clinician's Erythema Assessment (CEA) values given by two dermatologists. The Mexameter uses 568 nm and 660 nm LEDs and a photodetector for estimation of erythema index, while the used prototype device acquired RGB images at 460 nm, 530 nm and 665 nm LED illumination. Several erythema index estimation algorithms were compared to determine which one gives the best contrast between increased eryth…
Di nuovo schiave. Donne e distopia (2007-2022)
2022
Il saggio analizza le peculiarità e le costanti della narrativa distopica scritta da donne in Italia lungo un arco di tempo che va dal 2007 al 2022. Riallacciandosi a una tradizione mainstream che in ambito anglosassone ha prodotto libri di successo come The Handmaid’s Tale di Margaret Atwood, le distopie italiane degli ultimi anni mettono in scena un futuro in cui a dominare è una società marcatamente patriarcale che esercita un controllo violento sul corpo e sull’identità femminili. Il cupo futuro raccontato da Laura Pugno, Nicoletta Vallorani, Maria Rosa Cutrufelli, Laura Pariani e altre scrittrici italiane nasce dall’amplificazione di stereotipi sessuali radicati nel presente e vuole es…
Genetic and aromatic diversity of the Burgundy truffle
2013
Truffles are ectomycorrhizal Ascomycota fungi belonging to the Tuberaceae family and more specifically to the Tuber genus. More than thirty Tuber species are currently described in Europe. In this thesis, we specifically focused on the Tuber aestivum-uncinatum model. This truffle is commonly called "Burgundy Truffle" and has a gastronomic and cultural interest.The first part of this thesis focused on the taxonomic status of the Burgundy truffle (Tuber uncinatum). For this, we used a multi-marker approach combining several genetic markers commonly used at the interspecific scale. Our analyses showed that the two taxa, Tuber aestivum (summer truffle) and Tuber uncinatum are conspecific.In the…
