Binge-like alcohol exposure in adolescence: behavioural, neuroendocrine and molecular evidence of abnormal neuroplasticity … and return
2021
Binge alcohol consumption among adolescents affects the developing neural networks underpinning reward and stress processing in the nucleus accumbens (NAc). This study explores in rats the long-lasting effects of early intermittent exposure to intoxicating alcohol levels at adolescence, on: (1) the response to natural positive stimuli and inescapable stress
Rilevazione statistica della diffusione dei fenomeni di binge drinking, drunkoressia e gambling tra gli adolescenti palermitani
2017
L’obiettivo dello studio è l’analisi della diffusione dei comportamenti riconducibili ai fenomeni di Binge Drinking, Drunkoressia e Gambling in individui che possiedono un’età compresa tra i 13 e 20 anni: si è deciso di analizzare nello specifico tale fascia d’età poiché la propensione di alcuni soggetti ad assumere condotte pericolose per la propria salute risulta essere particolarmente alta proprio durante la fase adolescenziale. Quest’ultimo è infatti un periodo di intenso sviluppo neuro- cognitivo che conduce a cambiamenti importanti ai fini del comportamento, dell’affettività, della ricerca e della selezione di stimoli più gratificanti: il risultato è un aumento della predisposizione a…
Recent advances in smart biotechnology: Hydrogels and nanocarriers for tailored bioactive molecules depot
2017
Over the past ten years, the global biopharmaceutical market has remarkably grown, with ten over the top twenty worldwide high performance medical treatment sales being biologics. Thus, biotech R&D (research and development) sector is becoming a key leading branch, with expanding revenues. Biotechnology offers considerable advantages compared to traditional therapeutic approaches, such as reducing side effects, specific treatments, higher patient compliance and therefore more effective treatments leading to lower healthcare costs. Within this sector, smart nanotechnology and colloidal self-assembling systems represent pivotal tools able to modulate the delivery of therapeutics. A comprehens…
Immuno-oncological treatment of Non-Small-Cell Lung Cancer (NSCLC) in advanced stage with Nivolumab
2023
Immuno-oncology marked a therapeutic revolution in the treatment of cancer. Thanks to the new strategy that aims to awaken the immune system to fight cancer cells, there has been a change in the clinical course in the treatment of advanced Non-Small Cell Lung Cancer (NSCLC). Our study aimed to evaluate the therapeutic efficacy of nivolumab monotherapy in the treatment of patients with advanced stage IIIB/IV non-small cell lung cancer beyond the second line. The results showed a progression-free survival of 7.35 months and an improvement in the quality of life of patients compared to other treatments. In addition, no type 3 and type 4 adverse reactions were detected in patients treated with …
Meccanismi immunologici e molecolari del danno epatico da farmaci
2015
I polimorfismi genetici e/o i fattori ambientali, ad esempio l’alcol e/o i farmaci concomitanti, contribuiscono alla suscettibilità individuale nel determinare il danno epatico da farmaci. L’HLA si è dimostrato essere uno dei più importanti predittore di suscettibilità individuale anche per quei farmaci per i quali questa non era stata mai sospettata.
N-valproyl-aminoacids as new potential antiepileptic drugs: Synthesis, characterization and in vitro studies on stability
2015
Epilepsy, affecting at least 50 million persons worldwide, is one of the most common neurological disorders. Despite the significant advances in understanding epileptogenic mechanisms and in counteracting their pathological consequences, this clinical condition still has to be faced of treating more effectively the symptoms (epileptic seizures) and of preventing their unfavourable evolution. So far, research has been unsuccessful involved in developing effective antiepileptic drugs (AEDs) capable of preventing the development of the pathogenic process, set in motion by different etiological factors, that leads ultimately to chronic epilepsies .[1, 2] So, a substantial need remains to develo…
The Essential Oil of Thymbra capitata and its Application as A Biocide on Stone and Derived Surfaces
2019
Many chemicals used nowadays for the preservation of cultural heritage pose a risk to both human health and the environment. Thus, it is desirable to find new and eco-friendly biocides that can replace the synthetic ones. In this regard, plant essential oils represent effective alternatives to synthetic substances for the preservation of historical monuments. Thymbra capitata (syn. Thymus capitatus) is a medicinal and aromatic plant growing in the Mediterranean area and endowed with important pharmacological properties related to its essential oil. Among them, the antimicrobial ones make the T. capitata essential oil an ideal candidate for industrial applications
PEG-benzofulvene copolymer hydrogels for antibody delivery.
2010
A new amphiphilic copolymer have been synthesized starting from the hydrosoluble polyaspartylhydrazide (PAHy) polymer, by grafting both hydrophilic PEG(2000) chains and hydrophobic palmitic acid (C(16)) moieties on polymer backbone, and the structure of obtained PAHy-PEG(2000)-C(16) copolymer have been characterized by 2D (1)H/(13)C NMR experiments. PAHy-PEG(2000)-C(16) copolymer showed the ability of self-assembling in aqueous media giving a core-shell structure and resulted potentially useful for encapsulating and dissolving hydrophobic drug. The formation of micellar core-shell structure has been investigated by 2D (1)H NMR NOESY experiments. The presence of cross-peaks for protons of C(…
Effects in cigarette smoke stimulated bronchial epithelial cells of a corticosteroid entrapped into nanostructured lipid carriers
2014
Background Nanomedicine studies have showed a great potential for drug delivery into the lung. In this manuscript nanostructured lipid carriers (NLC) containing Fluticasone propionate (FP) were prepared and their biocompatibility and effects in a human bronchial epithelial cell line (16-HBE) stimulated with cigarette smoke extracts (CSE) were tested. Results Biocompatibility studies showed that the NLC did not induce cell necrosis or apoptosis. Moreover, it was confirmed that CSE increased intracellular ROS production and TLR4 expression in bronchial epithelial cells and that FP-loaded NLC were more effective than free drug in modulating these processes. Finally, the nanoparticles increased…
Bisphosphonate-polyaspartamide conjugates as bone targeted drug delivery systems.
2015
Poly-hydroxy-aspartamide was used as a backbone to synthesize bisphosphonate derivatives thus achieving macromolecular carriers to be potentially used as targeting agents for bone drug delivery. Molecules bearing bisphosphonate groups, such as aminobisphosphonate (ABP) and neridronate (NRD), have been conjugated to polyaspartamide (α,β-poly(N-2-hydroxyethyl)-dl-aspartamide, PHEA), with or without a spacer (succinic acid or 6-aminocaproic acid) thus obtaining PHEA-succinate-ABP and PHEA-caproylcarbamate-ABP and PHEA-ABP and PHEA-NRD, respectively. Bisphosphonate-polymer conjugates were physico-chemically characterized using size exclusion chromatography and 1H-NMR; and their in vitro and e…
