Naltrexone antagonizes acetaldehyde-induced increments in dopamine neurons activity
2014
Abstract Acetaldehyde is the main metabolite of ethanol ingested through alcoholic beverages. Traditionally considered aversive is presently being viewed as an activating agent of the mesolimbic dopamine system but underlying mechanisms are only partially known. Here we show that acetaldehyde-induced increase in firing rate, burst firing and spikes/burst of antidromically-identified ventro-tegmental area Nucleus Accumbens-projecting neurons are abolished by pretreatment with the opiate unselective antagonist naltrexone (1mg/kg/ip). Similar effects are obtained after administration of naloxone (0.1mg/kg/iv). These results indicate: 1) endogenous opiate system(s) participate in acetaldehyde-i…

Aproximación al perfil psicológico del usuario de esteroides anabolizantes no indicados
2019
El uso de esteroides anabolizantes androgénicos (EAA) no es un fenómeno reciente, pero ha experimentado una importante evolución en los últimos años, pasando de ser un problema muy localizado en los entornos del deporte profesional a extenderse en el ámbito de la práctica deportiva de recreo o estética, mediante el consumo no terapéutico de estos medicamentos o productos. En la literatura científica actual podemos encontrar como se abarca el estudio del uso no terapéutico de los EAA desde distintas perspectivas, desde un punto de vista estrictamente médico, en cuanto a los efectos adversos producidos por este uso incontrolado, pasando por estudios que se centran en estudiar la prevalencia d…

Eating and feeding disorders are common in pediatric age and may be important to discover and recover the early symptoms in order to optimize the treatment and management.
Search for low-energy neutrinos from astrophysical sources with Borexino
2019
We report on searches for neutrinos and antineutrinos from astrophysical sources performed with the Borexino detector at the Laboratori Nazionali del Gran Sasso in Italy. Electron antineutrinos ($\bar{\nu}_e$) are detected in an organic liquid scintillator through the inverse $\beta$-decay reaction. In the present work we set model-independent upper limits in the energy range 1.8-16.8 MeV on neutrino fluxes from unknown sources that improve our previous results, on average, by a factor 2.5. Using the same data set, we first obtain experimental constraints on the diffuse supernova $\bar{\nu}_e$ fluxes in the previously unexplored region below 8 MeV. A search for $\bar{\nu}_e$ in the solar ne…
Borexino’s search for low-energy neutrino and antineutrino signals correlated with gamma-ray bursts
2017
International audience; A search for neutrino and antineutrino events correlated with 2350 gamma-ray bursts (GRBs) is performed with Borexino data collected between December 2007 and November 2015. No statistically significant excess over background is observed. We look for electron antineutrinos ( ν¯e ) that inverse beta decay on protons with energies from 1.8 MeV to 15 MeV and set the best limit on the neutrino fluence from GRBs below 8 MeV. The signals from neutrinos and antineutrinos from GRBs that scatter on electrons are also searched for, a detection channel made possible by the particularly radio-pure scintillator of Borexino. We obtain currently the best limits on the neutrino f…

Brexit atspoguļojums "The Guardian" mājaslapā
2017
Lielbritānijas un Ziemeļīrijas Apvienotās Karalistes lēmums sasaukt referendumu par tās turpmāko likteni Eiropas Savienībā, ir piesaistījis pastiprinātu starptautisko uzmanību. Tika radīts jaunvārds, lai apzīmētu AK izstāšanos no ES – Brexit. Pētījums tika izstrādāts, lai izvērtētu, kā Brexit tika atspoguļots vienā no masu mediju avotiem. Ietekmīgais britu laikraksts The Guardian tika izvēlēts kā avots pētījuma korpusam. Empīrisko datu analīze tika balstīta uz R. Vodakas diskursa-vēsturiskās pieejas teorētiskajām atziņām, pievēršoties The Guardian vispārējāi nostājai pret Brexit. Lingvistiskās analīzes metodoloģisko rāmi veido četras diskursa-vēsturiskās pieejas stratēģijas: nosaukšana, apg…
studio osservazionale retrospettivo della correlazione tra riduzione della massa ossea e disturbi comportamentali
Nel nostro studio sono stati esaminati due gruppi di soggetti, così suddivisi, un gruppo già con diagnosi strumentale di riduzione della massa ossea ed un gruppo controllo. Nel reclutamento del gruppo di controllo sono stati esclusi soggetti di età superiore a 65 anni, in terapia cortisonica per patologie croniche da più di sei mesi, individui che evidenziano all’anamnesi fattori che aumentano il rischio o le conseguenze delle cadute, quali disabilità, fattori ambientali, consumo di benzodiazepine, abuso di alcol o droghe, o con patologie note che possano essere responsabili di osteoporosi secondaria. La scheda di valutazione anamnestica, nei pazienti affetti da osteoporosi o osteopenia è c…
