TUMORI a CELLULE GERMINALIin ETA' PEDIATRICA: FATTORI PROGNOSTICI del PROTOCOLLO AIEOP TCG 91.
2002
CIRCA IL 20% DEI PAZIENTI CON TUMORI A CELLULE GERMINALI (tcg) SONO RESISTENTI AL TRATTAMENTO. GLI aUTORI HANNO EFFETTUATO UNO STUDIO POLICENTRICO AL FINE DI RILEVARE CORRELAZIONI TRA PARAMETRI CLINOCO/LABORATORISTICI E LA PROGNOSI
I TUMORI A CELLULE GERMINALI: CLINICA E TERAPIA
1990
Gli studi embriologici ed anatomopatologici hanno chiarito le origini dei Tumori a cellule germinali e di classificarli in diversi tipi istologici, benigni e maligni, riconducibili al momento differenziativo durante il quale la cellula primordiale viene colpita da un imput o proliferativo o neoplastico. Viene esaminato ogni aspetto clinico con la migliore forma di terapia.
Functional characterisation of the first HSP110 inhibitors.
2023
Heat shock proteins are molecular chaperones highly expressed in haematological malignancies. My laboratory has shown that the heat shock protein HSP110 is a new and important therapeutic target In colorectal cancer and in non-Hodgkin's lymphoma. As there were no existing inhibitors of HSP110, a screening strategy of a chemical library was carried out and allowed the identification of two molecules capable of specifically inhibiting the chaperone activity of HSP110. My thesis objective was to characterise and functionally validate these newly identified molecules in diffuse large cell B lymphomas. I have shown that one of these molecules limits the interaction of HSP110 with the SYK signall…
Clivaggio e shuttling nucleo-citoplasmatico della proteina Sirt1, in cellule di carcinoma mammario MDA-MB231.
2013
Sirt1 è una proteina nota per il suo ruolo di istone deacetilasi NAD+ dipendente che sembra essere coinvolta in una ampia gamma di processi cellulari, quali regolazione genica, controllo dello stato metabolico, meccanismi di sopravvivenza allo stress. Dalla letteratura emergono dati contrastanti concernenti la funzione di Sirt1 nei tumori, le vengono infatti attribuiti ruoli sia di oncogene che di soppressore tumorale, argomento fortemente dibattuto. A conferma di ciò, la localizzazione subcellulare e la funzione di Sirt1 variano nei differenti tipi cellulari (1). E’ anche noto che Sirt1 risulta frequentemente clivata in varie linee cellulari grazie ad attività proteolitiche nucleari (2). Q…

CELLULE MESENCHIMALI NELLA PRATICA CLINICA: STATO SPERIMENTAZIONE E PROSPETTIVE DI APPLICAZIONE.
Study of the dynamics of biomolecules by high speed atomic force microscopy and surface enhanced Raman spectroscopy
2015
This thesis focuses on the coupling of High–Speed Atomic Force Microscopy (HS-AFM) and Surface Enhanced Raman Spectroscopy (SERS) for biomolecule analysis. We have designed a fabrication protocol to manufacture “SERS-active” substrates. The efficacy of gold, silver and gold-silver bimetallic crystalline nanoparticle substrates were evaluated. We have investigated the impact of optical and morphological features of the substrates on Raman signal intensity by analyzing well-known samples such as bipyridine ethylene and methylene blue molecules. We took an interest in three distinct biological problematics with HS-AFM and SERS analyses. First, we have detected the chemical signature of cytochr…

Utilisation of natural carotenoids from Momordica cochinchinensis (gac) as health compounds : extraction and bioactvity depending on the origin and o…
2014
The aril of Momordica cochinchinensis (gac), plant from the Cucurbitaceae family, is the richest source of lycopene and β-carotene, which are a strong antioxidant and a pro-vitamin A, respectively, interesting for health-complements. First, a process of soft extraction-fractionation was developed for extracting effectively the natural carotenoids from gac without loss of their original quality. Then, the lycopene and β-carotene extracted from gac were analyzed and characterized. At least 95% of the extracts were composed of the all-trans isomer. They were not degraded during the heat-treatment mimicking formulation processing. Their thermal stereo-mutation was evaluated. Lycopene is more an…
