El modulador alostérico negativo de los mGluR5, MPEP, potencia la reinstauración de la preferencia condicionada inducida con priming de cocaína
2019
Cocaine addiction is a chronic disorder with high relapse rates; therefore, understanding the neuronal mechanisms underlying drug-seeking during relapse is a priority to develop targeted pharmacotherapy. The metabotropic glutamate receptor 5 (mGluR5) seems to be involved in the reinstatement induced by cocaine-associated cues. The main objective of the study was to evaluate the efficacy of MPEP, a negative allosteric modulator of mGluR5, in attenuating or potentiating the reinstatement induced by priming doses of cocaine in the CPP paradigm, ultimately to further knowledge regarding the role of the mGluR5 in relapse into cocaine abuse. OF1 mice (48 female and 48 male) were conditioned in th…
Biodiversità e stenocoria all’interno delle diverse classi di vegetazione dei monti Peloritani: l’effetto dell’azione umana sugli spettri biologici e…
1998
Il bacino del Garda fu colonizzato dall'uomo sin dal Neolitico. Uno studio floristico effettuato tra il '92 ed il '94 lungo la sponda bresciana su una fascia compresa tra 0 e 100 m sul livello del lago, ha permesso di evidenziare le relazioni esistenti tra l'attività umana e la distribuzione di determinati contingenti floristici nell'area anzidetta. Gli interventi umani più evidenti sono stati i seguenti: * Bonifica, drenaggio o diserbo delle zone umide. Sostituzione con colture irrigue od attrezzature balneari. * Elimina-zione dei boschi ascrivibili all'ordine dei Populetalia albae dalle conoidi di deiezione e dalle sponde moreniche subpianeggianti a sud del bacino. Sostituzione con prati …
Effetti dell'attività antropica sulla flora spontanea delle coste benacensi.
1996
Viene presentato uno studio floristico effettuato tra il '92 ed il '94 lungo la sponda bresciana del lago di Garda, su una fascia compresa tra 0 e 100 m sul livello del lago. Tra le entità censite sono state distinte cinque diverse florule rappresentative dei diversi ambienti e tipi vegetazionali presenti nell'area studiata. La comparazione tra lo spettro biologico ed i gruppi corologici dell'elenco floristico generale e quelli di ciascuna florula, evidenzia differenze significative tra gli ambienti a confronto, che, nella stessa area, sono sottoposti a gradi di antropizzazione diversa: oltre a favorire l'insediamento di una ricca flora alloctona, l'azione antropica ha modificatol'equilibri…

Metabolic impact of adult-onset, isolated, growth hormone deficiency (AOiGHD) due to destruction of pituitary somatotropes.
2011
Growth hormone (GH) inhibits fat accumulation and promotes protein accretion, therefore the fall in GH observed with weight gain and normal aging may contribute to metabolic dysfunction. To directly test this hypothesis a novel mouse model of adult onset-isolated GH deficiency (AOiGHD) was generated by cross breeding rat GH promoter-driven Cre recombinase mice (Cre) with inducible diphtheria toxin receptor mice (iDTR) and treating adult Cre(+/-), iDTR(+/-) offspring with DT to selectively destroy the somatotrope population of the anterior pituitary gland, leading to a reduction in circulating GH and IGF-I levels. DT-treated Cre(-/-), iDTR(+/-) mice were used as GH-intact controls. AOiGHD im…
Hookworm-like eggs in children’s faecal samples from a rural area of Rwanda
2016
Background: Hookworm eggs identification and quantification is usually carried out by Kato-Katz method. However various structures present in the smear may be confused with eggs of such parasites. Objective: To document the presence of structures in Kato-Katz slides that could initially be misinterpreted as hookworm eggs. Method: 497 faecal samples were analysed by Kato-Katz technique, diphasic concentration technique, agar-plate coprocultive and larvae obtained were analysed by PCR and characterized by sequencing. Result: Hookworm-like eggs were found in 159 (32%) of the samples by Kato Katz, finally identified as Caenorhabditis elegans by PCR technique. Conclusion: The diagnosis of human …

Water Structure Recovery in Chaotropic Anion Recognition: High-Affinity Binding of Dodecaborate Clusters to γ-Cyclodextrin
2015
Dodecaborate anions of the type B12X12(2-) and B12X11Y(2-) (X=H, Cl, Br, I and Y=OH, SH, NH3(+), NR3(+)) form strong (K(a) up to 10(6) L mol(-1), for B12Br12(2-)) inclusion complexes with γ-cyclodextrin (γ-CD). The micromolar affinities reached are the highest known for this native CD. The complexation exhibits highly negative enthalpies (up to -25 kcal mol(-1)) and entropies (TΔS up to -18.4 kcal mol(-1), both for B12I12(2-)), which position these guests at the bottom end of the well-known enthalpy-entropy correlation for CDs. The high driving force can be traced back to a chaotropic effect, according to which chaotropic anions have an intrinsic affinity to hydrophobic cavities in aqueous …
Hierarchical-ACA DBEM for Anisotropic Three-Dimensional Time-Harmonic Fracture Mechanics
2012
A hierarchical BEM solver for the analysis of three-dimensional anisotropic time-harmonic fracture mechanics problems is presented. A thorough investigation on the relations and interactions between the numerically computed anisotropic fundamental solutions and the algorithm used to approximate the blocks of the hierarchical matrix, namely Adaptive Cross Approximation, is carried out leading to the employed computational strategy. The use of the hierarchical matrices and iterative solvers is proved as an effective technique for speeding up the solution procedure and reducing the required memory storage in time-harmonic three-dimensional anisotropic fracture mechanics problems.
