STATISTICAL ANALYSIS OF A SURVEY ABOUT DIFFUSION OF BINGE DRINKING AND DRUNKOREXIA AMONG YOUNG PEOPLE
2017
Youth alcohol consumption is a major global public health concern. Previous reviews have concluded that exposure to alcohol marketing was associated with drinking initiation and higher alcohol consumption among youth. From January to May 2017, a survey has been conducted through administration of questionnaires about the diffusion of binge drinking and drunkorexia among the students of Palermo. Test was administered, during school time, to 2331 students between the ages of 13 and 20. Regarding the analysis of the questionnaires, 97.8% of student declare to have drunk at least once: their first taste of alcoholic drink happens at the age of thirteen/fourteen. They prefer to drink at the disc…
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…
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 …
POSTPRANDIAL HYPERGLYCEMIA IS A DETERMINANT OF PLATELET ACTIVATION IN EARLY 2 DIABETES MELLITUS
2010
BACKGROUND: Chronic hyperglycemia is a major contributor to in vivo platelet activation in diabetes mellitus. OBJECTIVES: To evaluate the effects of acarbose, an alpha-glucosidase inhibitor, on platelet activation and its determinants in newly diagnosed type 2 diabetic patients. METHODS: Forty-eight subjects (26 males, aged 61 +/- 8 years) with early type 2 diabetes (baseline hemoglobin A(1c) < or = 7% and no previous hypoglycemic treatment) were randomly assigned to acarbose up to 100 mg three times a day or placebo, and evaluated every 4 weeks for 20 weeks. The main outcome measures were urinary 11-dehydro-thromboxane (TX)B(2) (marker of in vivo platelet activation) and 8-iso-prostaglandi…
Cathepsin L in metastatic bone disease: therapeutic implications
2010
AbstractCathepsin L is a lysosomal cysteine proteinase primarily devoted to the metabolic turnover of intracellular proteins. However, accumulating evidence suggests that this endopeptidase might also be implicated in the regulation of other important biological functions, including bone resorption in normal and pathological conditions. These findings support the concept that cathepsin L, in concert with other proteolytic enzymes involved in bone remodeling processes, could contribute to facilitate bone metastasis formation. In support of this hypothesis, recent studies indicate that cathepsin L can foster this process by triggering multiple mechanisms which, in part, differ from those of t…
A Curcumin-BODIPY Dyad and Its Silica Hybrid as NIR Bioimaging Probes
2022
In this paper we describe the synthesis of a novel bichromophoric system in which an efficient photoinduced intercomponent energy transfer process is active. The dyad consists of one subunit of curcumin and one of BODIPY and is able to emit in the far-red region, offering a large Stokes shift, capable of limiting light scattering processes for applications in microscopy. The system has been encapsulated in MCM-41 nanoparticles with dimensions between 50 and 80 nm. Both the molecular dyad and individual subunits were tested with different cell lines to study their effective applicability in bioimaging. MCM-41 nanoparticles showed no reduction in cell viability, indicating their biocompatibil…

Curcumin as a possible lead compound against hormone-independent, multidrug-resistant breast cancer
2009
We examine the possible evidence that the phytochemical curcumin may overcome resistance to hormonal and cytotoxic agents in breast cancer. We present our observations on MCF-7R, a multidrug-resistant (MDR) variant of the MCF-7 breast cancer cell line. In contrast to MCF-7, MCF-7R lacks aromatase and estrogen receptor alpha (ERalpha) and overexpresses the multidrug transporter ABCB1 and the products of different genes implicated in cell proliferation and survival, like c-IAP-1, NAIP, survivin, and COX-2. Nevertheless, in cytotoxicity and cell death induction assays, we found that the antitumor activity of curcumin is substantial both in MCF-7 and in MCF-7R. We elaborated the diketone system…
LE VARIANTI DEL GENE CYP2C19 NELLA FARMACO-GENOMICA DEL CLOPIDOGREL
2010
Il clopidogrel per espletare la propria funzione di antiaggregante piastrinica necessita l’intervento di diversi citocromi epatici. Le varianti del gene CYP2C19 sembrano influenzarne sensibilmente l’attivazione e pertanto l’azione farmacologica. Sono stati identificati tre alleli principali. L’allele CYP2C19*1 è il wild type e codifica per un enzima costituzionalmente attivo. Gli alleli CYP2C9*2 e CYP2C9*3 codificano invece per forme enzimatiche parzialmente funzionanti e sono responsabili sia in eterozigosi che in omozigosi della variazione di attività farmacologica. La valutazione delle varianti è stata eseguita mediante le metodiche PCR-RFLP e sequenziamento diretto. Abbiamo allestito du…
