Journal ArticleDOI
Y-TZP ceramics for artificial joint replacements
Corrado Piconi,W. Burger,H.G. Richter,A. Cittadini,Giulio Maccauro,Valeria Covacci,N. Bruzzese,G.A. Ricci,E. Marmo +8 more
TL;DR: Samples made out Yttria coated powders show lower strength degradation than samples made out coprecipitated powders, and UHMWPE discs coupled to Y-TZP rings made out coated powder do not show increase in wear after repeated sterilization cycles of the ceramic rings.
Journal ArticleDOI
In vitro evaluation of the mutagenic and carcinogenic power of high purity zirconia ceramic.
Valeria Covacci,N. Bruzzese,Giulio Maccauro,C. Andreassi,G.A. Ricci,Corrado Piconi,E. Marmo,W. Burger,Achille Cittadini +8 more
TL;DR: It is shown that ceramic from high purity powders can be considered suitable for biomedical applications from the point of view of the effects of its radioactive impurity content, and the mutagenic and transforming effects of Y-TZP ceramic are demonstrated.
Journal ArticleDOI
Regulation of cell cycle progression and apoptosis by beta-carotene in undifferentiated and differentiated HL-60 leukemia cells: possible involvement of a redox mechanism.
Paola Palozza,Simona Serini,Angela Torsello,Alma Boninsegna,Valeria Covacci,Nicola Maggiano,Franco O. Ranelletti,Federica I. Wolf,Gabriella Calviello +8 more
TL;DR: Evidence is provided that β‐carotene modulates molecular pathways involved in cell cycle progression and apoptosis and support the hypothesis that a redox mechanism may be implicated and suggest that differentiated cells may be less susceptible to the carotenoid than highly neoplastic undifferentiated cells.
Journal ArticleDOI
Oxidative DNA damage as a marker of aging in WI-38 human fibroblasts.
Federica I. Wolf,Angela Torsello,Valeria Covacci,Silvia Fasanella,Micaela Montanari,Alma Boninsegna,Achille Cittadini +6 more
TL;DR: Results lend support to the concept that oxidative stress may be a key determinant of aging by demonstrating that DNA damage in old/58 PDs cells reflects both an increased susceptibility to oxidative stress and a reduced efficiency of repair mechanisms.
Journal ArticleDOI
DNA oxidative damage during differentiation of HL-60 human promyelocytic leukemia cells.
Valeria Covacci,Angela Torsello,Paola Palozza,Alessandro Sgambato,Giampiero Romano,Alma Boninsegna,and Achille Cittadini,Federica I. Wolf +7 more
TL;DR: In this article, DNA oxidative damage was measured in human promyelocytic leukemia HL-60 cells, in the same cells committed to granulocytic differentiation with dimethyl sulfoxide (DMSO) or all-trans-retinoic acid (RA) and in mature human peripheral granulocytes (HPG).
