Fake Landscapes
2016
L'articolo affronta i risvolti architettonici del camuffamento strategico effettuato per scopi militari durante la Seconda Guerra Mondiale. Si tratta di una pratica particolare messa in atto soprattutto in California nascondendo con enormi teloni dipinti interi edifici o capannoni facendolo apparire come altre cose e quindi evitando il riconoscimento da parte dei bombardieri. Si trattava quindi di fatto di ampie operazioni di land art o di un ambito dove l'architettura del paesaggio incontra la scenografia. Camouflage was a strategic technique used during the Second World War mainly in California but aslo elsewhere. It consisted in a massive operation on the landscape. The essay analyses it…
Magnetic functionalities in MOFs: from the framework to the pore
2017
In this review, we show the different approaches so far developed to prepare Metal-Organic Frameworks (MOFs) presenting electronic functionalities, with particular attention to magnetic properties. We will cover the chemical design of the framework necessary for the incorporation of different magnetic phenomena, as well as the encapsulation of functional species in the pores leading to hybrid multifunctional MOFs combining an extended lattice with a molecular lattice.
Inhibition of HSP70: a challenging anti-cancer strategy.
2012
HSP70 is a chaperone that accumulates in the cells after many different stresses promoting cell survival in response to the adverse conditions. In contrast to normal cells, most cancer cells abundantly express HSP70 at the basal level to resist to various insults at different stages of tumorigenesis and during anti-cancer treatment. This cancer cells addiction for HSP70 is the rational for its targeting in cancer therapy. Much effort has been dedicated in the last years for the active search of HSP70 inhibitors. Additionally, the recent clinical trials on highly promising inhibitors of another stress protein, HSP90, showed compensatory increase in HSP70 levels and raised the question of nec…
From a Better Understanding of the Mechanisms of Action of Histone Deacetylases Inhibitors to the Progress of the Treatment of Malignant Lymphomas an…
2017
Background Notable progress has been made in chemo- and immunotherapy of B-cell lymphomas, but less in the treatment of T-cell lymphomas. Objective Histone deacetylases inhibitors are a potentially useful therapeutic mean, as an epigenetic dysregulation is present in lymphomas, and especially in T-cell types. We aimed to study the progress made in this area. Method A mini-review was achieved using the articles published in PubMed in the last two years and the new patents made in this field. Results Histone deacetylases inhibitors are involved in the derepression of tumor suppressor genes through a histone deacetylase-mediated transcriptional process. Their inhibition is followed by cell cyc…
Cathepsin D expression levels in nongynecological solid tumors: clinical and therapeutic implications.
2004
Cathepsin D is a lysosomal acid proteinase which is involved in the malignant progression of breast cancer and other gynecological tumors. Clinical investigations have shown that in breast cancer patients cathepsin D overexpression was significantly correlated with a shorter free-time disease and overall survival, whereas in patients with ovarian or endometrial cancer this phenomenon was associated with tumor aggressiveness and a degree of chemoresistance to various antitumor drugs such as anthracyclines, cis-platinum and vinca alkaloids. Therefore, a lot of research has been undertaken to evaluate the role and the prognostic value of cathepsin D also in other solid neoplasms. However, conf…
Association study of 44 candidate genes with depressive and anxiety symptoms in post-partum women.
2009
The post-partum period is a time of extreme vulnerability for a whole spectrum of psychiatric disorders. Delivery may be considered an important risk factor in genetically susceptible women. Five hundred and eight SNPs in 44 genes at candidate pathways putatively related to mood changes after delivery were genotyped in a multicenter cohort of 1804 women from Spain. Participants completed two scales at 2-3 days, 8 weeks, and 32 weeks post-partum, the Edinburgh Post-partum Depression Scale (EPDS) and the Spielberger State-Trait Anxiety Inventory (STAI). Those women who scored 9 or more on EPDS were evaluated for major depression using the Diagnostic Interview for Genetics Studies (DIGS) adapt…
Comparison among different rainfall energy harvesting structures
2018
In this paper, an experimental comparison between different rainfall harvesting devices through the study of the electrical rectifying circuit is proposed. In more detail, three harvesting structures are considered: the cantilever, the bridge and the floating circle. Different waveforms were acquired and discussed. The processed data were compared in order to suggest the best choice for the rectifying circuit, from the simplest one to that most frequently endorsed in the technical literature.
The mixed capacitated general routing problem with turn penalties
2011
In this paper we deal with the mixed capacitated general routing problem with turn penalties. This problem generalizes many important arc and node routing problems, and it takes into account turn penalties and forbidden turns, which are crucial in many real-life applications, such as mail delivery, waste collection and street maintenance operations. Through a polynomial transformation of the considered problem into a Generalized Vehicle routing problem, we suggest a new approach for solving this new problem by transforming it into an Asymmetric Capacitated Vehicle routing problem. In this way, we can solve the new problem both optimally and heuristically using existing algorithms. A powerfu…
Il principio di gerarchia delle resistenze capacity design
2012
The devastating effects generated by earthquakes occurred in different parts of the world have attract at a major interest in Earthquake Engineering. This branch of Structural Engineering studies the response and capacity of structural systems subjected to seismic actions, and develops design and prediction methods aimed at achieving adequate safety standards in presence of seismic events. A strategy used for the seismic prediction of RC structures, based on the capacity design of structural elements is the "hierarchy of strengths" (HS) principle. The paper shows how a proper use of the HS capacity design method can be included within the seismic design of RC structures achieving high level…
Retrofitting of Existing Steel MR-Frames by Encasing the Columns
2005
Summary The study concerns the behaviour of steel MR-frames subjected to vertical and lateral forces, not properly designed according to capacity design criteria, and upgraded by means of encasing the steel columns with concrete having different grade. The purpose of the paper is to examine if the proposed technique allows one to adequately increase the lateral stiffness and the resistance of the frames. Pushover analyses on multi-storey frames are performed trough a non-linear calculus program, able to take into account of the second order effects. The behaviour of frames with encased columns was compared with those of the bare frames, highlighting that with the proposed technique it is po…
