3D Integration : towards high-performance innovative imaging sensors
2017
Nowadays, CMOS image sensors are almost exclusively architectured around analog pixels. A transition to purely digital pixels would significantly improve the performances of imagers. Unfortunately, such an approach is difficult to consider because it causes an oversized and unusable pixel for the consumer market. One of the promising ways to solve this problem of pixel integration is to think not only in 2D dimensions, but in 3D dimensions by distributing the different functionalities on several interconnected wafers.Thus, the work presented in this manuscript describes the design of a purely digital image sensor in CMOS 3D-IC 130 nm Tezzaron technology. This sensor is architectured around …
COVID-19: dalle indicazioni ministeriali per la fase 2 alla nuova visione di odontoiatria sicura, sostenibile e centrata sul paziente
2020
La pandemia COVID-19, originaria di Wuhan in Cina, è diventata una grande sfida per la salute pubblica globale, modificando radicalmente la vita di tutti i giorni e le attività lavorative, specialmente quelle di ambito sanitario tra cui l’attività odontoiatrica. È stato necessario attuare delle misure di controllo delle infezioni per prevenire ulteriori diffusioni del virus. L’alto livello di attenzione che si è riusciti a raggiungere nella fase acuta della pandemia stessa ha determinato un efficiente bio-contenimento. Si impone, sin dalla fase 2, un ragionato e idoneo adeguamento di protocolli operativi di prevenzione e protezione. Prudenza, perizia e diligenza devono essere i punti cardin…
Recensione di Carolina Castellano, Una questione di provincia. Criminalità e camorra tra età giolittiana e fascismo, Editoriale Scientifica, Napoli, …
2021
Il volume Una questione di provincia, pubblicato nel 2020 dalla napoletana editoriale Scienti fica, si concentra sull’analisi delle «forme peculiari della criminalità camorrista» (p. 15) tra età giolittiana e fascismo nell’area dell’agro napoletano estesa fra le pendici del Vesuvio e la piana di nola, la piana del Volturno e l’area intorno ad Aversa.
Membrane vesicles shed by oligodendroglioma cells induce neuronal apoptosis.
2006
In order to investigate the mechanism by which oligodendrogliomas cause neuronal damage, media conditioned by G26/24 oligodendroglioma cells, were fractionated into shed vesicles and vesicle-free supernatants, and added to primary cultures of rat fetal cortical neurons. After one night treatment with vesicles, a reproducible, dose-dependent, inhibitory effect on neurite outgrowth was already induced and, after 48-72 h of incubation, neuronal apoptosis was evident. Vesicle-free supernatants and vesicles shed by NIH-3T3 cells had no inhibitory effects on neurons. Western blot analyses showed that treated neurons expressed a decreased amount of neurofilament (NF), growth-associated protein (GA…
Chemotherapy-induced apoptosis in hepatocellular carcinoma involves the p53 family and is mediatedviathe extrinsic and the intrinsic pathway
2010
We investigated the downstream mechanisms by which chemotherapeutic drugs elicit apoptosis in hepatocellular carcinoma (HCC). Genomic signatures of HCC cell lines treated with different chemotherapeutic drugs were obtained. Analyses of apoptosis pathways were performed and RNA interference was used to evaluate the role of the p53 family. Endogenous p53, p63 and p73 were upregulated in response to DNA damage by chemotherapeutic drugs. Blocking p53 family function led to chemoresistance in HCC. Stimulation and blocking experiments of the CD95-, the TNF- and the TRAIL-receptor systems revealed that cytotoxic drugs, via the p53 family members as transactivators, can trigger expression of each o…
Autocrine production of interleukin-4 and interleukin-10 is required for survival and growth of thyroid cancer cells.
2006
AbstractAlthough CD95 and its ligand are expressed in thyroid cancer, the tumor cell mass does not seem to be affected by such expression. We have recently shown that thyroid carcinomas produce interleukin (IL)-4 and IL-10, which promote resistance to chemotherapy through the up-regulation of Bcl-xL. Here, we show that freshly purified thyroid cancer cells were completely refractory to CD95-induced apoptosis despite the consistent expression of Fas-associated death domain and caspase-8. The analysis of potential molecules able to prevent caspase-8 activation in thyroid cancer cells revealed a remarkable up-regulation of cellular FLIPL (cFLIPL) and PED/PEA-15, two antiapoptotic proteins whos…
Tra «pentoloni per il solfato ammonico» e «un numero inverosimile di tubi»: le lettere di Carlo Emilio Gadda all’Ammonia Casale
2022
The essay analyzes the correspondence between Carlo Emilio Gadda and the "Ammonia Casale S.A." which intermittently covers a period from April 1927 to January 1940, with a long break between the autumn of 1931 and the spring of 1936. It is a decisive period of time on the public and private level. Reading the correspondence allows you to retrace an entire page of the history of Italian industry under fascism from an eccentric perspective.
Reversible stress-induced lipid body formation in fast twitch rat myofibers
2012
We analyzed the existence of lipid bodies (LBs) in the fast twitch rat flexor digitorum brevis (FDB) myofibers and found that these structures were scarce. However, isolation procedure of the myofibers, heath shock, viral infection or the glycosylation inhibitor tunicamycin induced formation of the LBs, which were stationary structures flanking Z lines. We next infected FDB myofibers with recombinant Semliki Forest virus expressing caveolin 3-yellow fluorescent protein (cav3-YFP) since this chimeric protein was targeted to the LBs facilitating their further analysis. Photobleaching experiments showed that the LBs recovered cav 3-YFP extremely slowly, indicating that they were not continuous…
