Teoria e pratica dei capitali urbani. La forma temporale e monetaria della città
2007
Questa monografia affronta il tema dei mercati immobiliari urbani, muovendosi su tre livelli: il livello della teoria del capitale di matrice speculativo-finanziaria (basata su principi economici post-keynesiani) che fornisce gli elementi teorici per comprendere le connessioni tra i mercati finanziari internazionali e i mercati immobiliari urbani, e le trasmutazioni di liquidità che trasformano i beni capitali immobiliari in beni moneta; il livello degli strumenti di analisi estimativa che consentono di indagare e di rappresentare le caratteristiche dei segmenti di mercato; il livello della verifica conoscito-operativa nel mercato immobiliare urbano, che analizza i mutamenti della forma tem…
Tolerance, Adaptation, and Cell Response Elicited by Micromonospora sp. Facing Tellurite Toxicity: A Biological and Physical-Chemical Characterization
2022
The intense use of tellurium (Te) in industrial applications, along with the improper disposal of Te-derivatives, is causing their accumulation in the environment, where oxyanion tellurite (TeO32−) is the most soluble, bioavailable, and toxic Te-species. On the other hand, tellurium is a rare metalloid element whose natural supply will end shortly with possible economic and technological effects. Thus, Te-containing waste represents the source from which Te should be recycled and recovered. Among the explored strategies, the microbial TeO32− biotransformation into less toxic Te-species is the most appropriate concerning the circular economy. Actinomycetes are ideal candidates in…
Annealing study of bismuth thin films
2010
Electrical and magnetotransport properties of thin bismuth films were studied in the range of 4.2 - 295 K in applied magnetic fields up to 3.5 T. The bismuth films were deposited on mica and SiO substrates and subjected to post deposition thermal annealing in order to improve the crystal structure. Annealed films showed lower resistivities and higher magnetoresistance as compared to the non annealed samples, however, the resistivity behavior was non-metallic and the mean grain size in the films were not significantly increased. A two carrier model for magnetoresistance and Hall coefficient was used to extract carrier mobilities and concentrations from the transport data.

Detailed spectroscopy of 193Bi
2015
An experiment aiming to study shape coexistence in 193Bi has been performed. Due to its transitional character, it has an exceptionally large number of structures identified close to the yrast line. Many new states have been found, significantly extending the previously known level scheme of 193Bi, including several new rotational bands. The π i13/2 band was extended to I π = 45/2+. The I π = 31/2+ member of the π i13/2 band was found to de-excite also to a long-lived isomeric state. This isomeric state is located at 2350 keV and has a spin and parity of 29/2+. The half-life of the isomeric state was measured to be 85(3) μs and it decays via the emission of an 84 keV E2 transition. A level …
Effect of Non-Surgical Periodontal Treatment on Oxidative Stress Markers in Leukocytes and Their Interaction with the Endothelium in Obese Subjects w…
2020
Aim: The primary objective of this pilot study was to evaluate the effect of non-surgical periodontal treatment. The secondary aim was to evaluate the effect of dietary therapy on both parameters of oxidative stress in leukocytes and leukocyte-endothelial cell interactions in an obese population. Methods: This was a pilot study with a before-and-after design. Forty-nine obese subjects with periodontitis were randomized by means of the minimization method and assigned to one of two groups, one of which underwent dietary therapy while the other did not. All the subjects underwent non-surgical periodontal treatment. We determined periodontal, inflammatory and oxidative stress parameters&mdash
Química supramolecular y aspectos biomédicos de azamacrociclos [1+1] de 1H-pirazol
2019
En este trabajo se presenta la síntesis y la caracterización de dos nuevas familias de ligandos azamacrocíclicos [1+1] constituidos por la unidad de 1H–pirazol y por una poliamina de distinta naturaleza. La primera familia está formada por cinco ligandos, los cuales se encuentran constituidos por la unidad de 1H–pirazol y por una poliamina de cadena abierta: L1–L5. La segunda familia está formada por tres ligandos de tipo escorpiando, los cuales se encuentran constituidos por la unidad de 1H–pirazol y por la poliamina tris(2–aminoetil)amina, que puede incorporar en su estructura la unidad de antraceno y la unidad de trifenilamina (TPA): L6–L8. El comportamiento ácido–base, así como la quími…
Oxidative Stress and Antioxidant Levels in Patients with Anorexia Nervosa after Oral Re-alimentation: A Systematic Review and Exploratory Meta-analys…
2015
Oxidative stress markers seem to be higher in patients with anorexia nervosa (AN) than healthy controls, but the potentially beneficial effects of weight gain is not known. We calculated random effects standardised mean differences (SMDs) as effect size measures of oxidative stress marker changes after re-alimentation reported in two or more studies, summarising others descriptively. Seven longitudinal studies (n = 104) were included. After a median follow-up period of 8 weeks, AN patients significantly increased their body mass index (15.1 ± 2.1 to 17.1 ± 2.2, p < 0.0001). This weight gain was followed by a significant increase in serum levels of the antioxidant albumin (studies = 6, SM…
Activation of the p38MAPK cascade is associated with upregulation of TNF alpha receptors in the spinal motor neurons of mouse models of familial ALS.
2005
Phosphorylated p38 mitogen-activated protein kinase (p38MAPK), but not activated c-jun-N-terminal kinase (JNK), increases in the motor neurons of transgenic mice overexpressing ALS-linked SOD1 mutants at different stages of the disease. This effect is associated with a selective increase of phosphorylated MKK3-6, MKK4 and ASK1 and a concomitant upregulation of the TNFalpha receptors (TNFR1 and TNFR2), but not IL1beta and Fas receptors. Activation of both p38 MAPK and JNK occurs in the activated microglial cells of SOD1 mutant mice at the advanced stage of the disease; however, this effect is not accompanied by the concomitant activation of the upstream kinases ASK1 and MKK3,4,6, while both …
