The mechanism of radiation-induced frank strand break formation in irradiated 5-bromo-2'-deoxyuridine (BrdU)-labelled DNA is still unclear despite the proven radiosensitizing properties of BrdU. Combination of ESR spectroscopy and quantum chemical modelling points to a simple reaction between the uridine-5-yl radical and water molecules that produces the(More)
Radiation-produced electrons initiate various reaction processes that are important to radiation damage to biomolecules. In this work, the site of attachment of the prehydrated electrons with methylacetoacetate (MAA, CH3-CO-CH2-CO-OCH3) at 77 K and subsequent reactions of the anion radical (CH3-CO•-CH2-CO-OCH3) in the temperature range (77 to ca. 170 K)(More)

In this work, we tested our hypothesis that surface chemistry and antioxidant properties of cerium nanoparticles (CNPs) are affected by presence of counterions. We first employed various precursor cerium (III) (Ce(III)) salts with different counterions (acetate, nitrate, chloride, sulfate) to synthesize CNPs following the same wet chemical methodology.(More)
Gli AA. studiano, con l'aiuto del microscopio ottico ed elettronico, la seatosi epatica del diabetico. Si insiste sulle modificazioni di struttura della cellula epatica già sovraccaricata di glicogeno, che caratterizzano in qualche modo il diabete mellito. Commentando le modalità fisiopatologiche del sovraccarico grasso del fegato diabetico, gli AA.(More)
E' stata studiata la struttura ultramicroscopica delle cellule endoteliali epatiche su materiale bioptico ottenuto da 28 diabetici e 2 soggetti sani: a) presenza di proliferazione delle cellule endoteliali piuttosto imponente; b) frequentissima ipertrofia, fino a diverse volte il diametro cellulare normale, tale da dare frequentemente l'obliterazione del(More)
The CBM Collaboration proposes to build a dedicated heavy-ion experiment to investigate the properties of highly compressed baryonic matter as it is produced in nucleus-nucleus collisions at the future accelerator facility in Darmstadt. Our goal is to explore the QCD phase diagram in the region of moderate temperatures but very high baryon densities. The(More)
