La pomice per il confezionamento di calcestruzzi leggeri strutturali
2011
The possibility of using pumice aggregates for concrete in structural applications is discussed. In particular, the mix design of lightweight concrete for the manufacturing masonry units having proper strength, is discussed. Moreover, the design of the unit shape according to the technical code requirements and making it possible to arrange reinforcing steel bars is described. Reinforced bearing masonry walls, made with the concrete units in question, were manufactured and tests on the panels and on the designed units were carried out. For comparison, tests on concrete units and structural elements were carried out after the substitution of pumice aggregates with ordinary lightweight aggreg…

Physical and biological properties of electrospun poly(d,l‐lactide)/nanoclay and poly(d,l‐lactide)/nanosilica nanofibrous scaffold for bone tissue en…
2021
Abstract Electrospun scaffolds exhibiting high physical performances with the ability to support cell attachment and proliferation are attracting more and more scientific interest for tissue engineering applications. The inclusion of inorganic nanoparticles such as nanosilica and nanoclay into electrospun biopolymeric matrices can meet these challenging requirements. The silica and clay incorporation into polymeric nanofibers has been reported to enhance and improve the mechanical properties as well as the osteogenic properties of the scaffolds. In this work, for the first time, the physical and biological properties of polylactic acid (PLA) electrospun mats filled with different concentrat…
Neutrophil extracellular traps arm DC vaccination against NPM-mutant myeloproliferation
2022
Neutrophil extracellular traps (NETs) are web-like chromatin structures composed by dsDNA and histones, decorated with antimicrobial proteins. Their interaction with dendritic cells (DCs) allows DC activation and maturation toward presentation of NET-associated antigens. Differently from other types of cell death that imply protein denaturation, NETosis preserves the proteins localized onto the DNA threads for proper enzymatic activity and conformational status, including immunogenic epitopes. Besides neutrophils, leukemic cells can release extracellular traps displaying leukemia-associated antigens, prototypically mutant nucleophosmin (NPMc+) that upon mutation translocates from nucleolus …
Tumor protein 53-induced nuclear protein 1 expression is repressed by miR-155, and its restoration inhibits pancreatic tumor development.
2007
Pancreatic cancer is a disease with an extremely poor prognosis. Tumor protein 53-induced nuclear protein 1 ( TP53INP1 ) is a proapoptotic stress-induced p53 target gene. In this article, we show by immunohistochemical analysis that TP53INP1 expression is dramatically reduced in pancreatic ductal adenocarcinoma (PDAC) and this decrease occurs early during pancreatic cancer development. TP53INP1 reexpression in the pancreatic cancer-derived cell line MiaPaCa2 strongly reduced its capacity to form s.c., i.p., and intrapancreatic tumors in nude mice. This anti-tumoral capacity is, at least in part, due to the induction of caspase 3-mediated apoptosis. In addition, TP53INP1 −/− mouse embryonic…
Anidulafungin in combination with amphotericin B against Aspergillus fumigatus.
2009
ABSTRACT We investigated the effects of anidulafungin alone and in combination with amphotericin B against Aspergillus fumigatus . Indifference was the only type of interaction observed in vitro. Anidulafungin at 1 and 5 mg/kg of body weight/day, amphotericin B at 1 mg/kg/day, and combination therapy prolonged the survival of mice with invasive aspergillosis. Anidulafungin at 5 mg/kg/day, alone and in combination with amphotericin B, reduced the kidney fungal burden. Overall, the combination was not superior to the most active single drug.
DYSMICROBISM, INFLAMMATORY BOWEL DISEASE AND THYROIDITIS: ANALYSIS OF THE LITERATURE
2015
The human body is colonized by a large number of microbes that are collectively referred to as the microbiota. They interact with the hosting organism and some do contribute to the physiological maintenance of the general good health thru regulation of some metabolic processes while some others are essential for the synthesis of vitamins and short-chain fatty acids. The abnormal variation, in the quality and/or quantity of individual bacterial species residing in the gastro-intestinal tract, is called dysmicrobism. The immune system of the host will respond to these changes at the intestinal mucosa level which could lead to Inflammatory Bowel Diseases (IBD). This inflammatory immune respo…
COLON MICROBIAL COMPOSITION IS CORRELATED WITH THE SEVERITY OF COLITIS INDUCED BY 2,4,6-TRINITROBENZESULFONIC ACID IN MICE.
2016
The objective of this study was to evaluate the changes in some bacterial species of colonic microbiota, the clinical signs and the intestinal changes in mice with 2,4,6-trinitrobenzenesulfonic acid (TNBS) induced colitis. CD-1 male mice were randomly divided into three groups and inoculated intrarectally with saline ethanol or TNBS solutions. ethanol and TNBS treatments induced weight loss accompained by mild and severe inflammation of the colon mucosa, respectively. however, TNBS-treated mice displayed significant differences compared to the saline group in terms of disease activity index and histological scoring. Both ethanol and TNBS groups showed an increased prevalence of escherichia …

The production management of hazelnuts in province of Cuneo, under a system dynamics approach. How the dormice affect its performance.
2019
The production of hazelnuts represents an important resource in several Italian rural areas. Sicily and Piedmont, ones of the most important producers of hazelnuts, are affected by the presence of a rodent (Glis Glis), that has reduced considerably the production of hazelnuts. This project aims to show the complexity of the issue by using a System Dynamics (SD) approach to help the decision-makers to implement an optimal policy to improve the performance of production management of hazelnuts, taking as example the case of Province of Cuneo. By using the case of Province of Cuneo where Policy-makers have applied some policies to reduce the impact of the presence of the rodent, a SD microworl…
