Resilience to social defeat stress in adolescent male mice.

2022

Adverse social experiences during adolescence are associated with the appearance of mental illness in adulthood. Social defeat (SD) is an ethologically valid murine model to study the consequences of social stress. In adolescent mice, SD induces depressive-like behaviors, increased anxiety and potentiates the reinforcing effects of cocaine and alcohol. However, not all mice exposed to SD will be susceptible to these effects. Adult mice resilient to the effects of SD show a consistent phenotype being resilient to depressive-like behaviors and to the increase in cocaine and alcohol consumption. The aim of the present study was to characterize the resilient phenotype to depressive-like behavio…

C3N4/reduced graphene oxide photocatalysts loaded with Ag or Ag/Pt for H2 evolution from aqueous solution of triethanolamine

2023

Composites of C3N4/reduced graphene oxide have been used as photocatalysts for triethanolamine photo- reforming with H2 generation in aqueous solution. The rate of H2 production over the Ag loaded best per- forming photocatalyst reached 525 μmol⋅h

Pre-treatment with high doses of cocaine decreases the reinforcing effects of cocaine in the conditioned place preference paradigm.

2012

The aim of the present study was to determine if pre-exposure to high doses of cocaine can subsequently alter the rewarding effects of this drug. Adult male mice received a pretreatment of physiological saline, or 12.5 or 25 mg/kg of cocaine (one injection a day for five days). After an interval of six days without injections, the rewarding effects of low doses of cocaine (0.5, 1 or 1.5 mg/kg) were evaluated in the conditioned place preference (CPP) paradigm. Doses of 1 and 1.5 mg/kg induced a clear CPP in animals pre-treated with saline but were ineffective in those pre-treated with 25 mg/kg of cocaine. Only the dose of 1.5 mg/kg induced CPP in mice pre-treated with 12.5 mg/kg of cocaine. …

Prenatal attachment in women subjected to fetal echocardiography

2012

ackground The experience of fetal echocardiography (as advanced level screening, usually done between 19th and 23rd week of gestation) is a complex psychological condition for mothers. It can influences the relationship they structure with themselves and their future children. Sometimes this examination can result in a diagnosis of fetal congenital heart disease. This event could be critical for the psychological representation of the child, made by mother, pushing her to an emotional blockage or hyper involvement (Righetti, Di Bernardo, Maggino, 2008) . In continuity with specific studies on this topic (ibidem), this research study investigates the configuration of prenatal attachment bond…

Color stability of CAD/CAM Zirconia ceramics following exposure to acidic and staining drinks.

2017

Background The aim of this in vitro study was to evaluate the color stability of CAD/CAM Zirconia ceramics following exposure to acidic drink (Coca Cola) and after exposure to staining solution (coffee). Material and Methods All the samples were immersed in different staining solutions over a 28-day test period. A colorimetric evaluation according to the CIE L*a*b* system was performed by a blind trained operator at 7, 14, 21, 28 days of the staining process. Shapiro Wilk test and Kruskal-Wallis ANOVA were applied to assess significant differences among restorative materials. Paired t-test was applied to test which CIE L*a*b* parameters significantly changed after immersion in staining solu…

Usos y abusos de drogas en contextos de prostitución

2010

Este trabajo examina los riesgos asociados al consumo de drogas en distintos entornos de prostitución (calle, clubs, saunas, apartamentos), a partir de los datos obtenidos mediante una encuesta a 260 mujeres que ejercían la prostitución y ocho grupos de discusión en seis provincias españolas. El consumo de alcohol, tabaco y cocaína fueron las drogas más usadas, con un patrón de consumo instrumental (excepto el tabaco), para facilitar la realización de los servicios sexuales. Las probabilidades de consumo de alcohol y cocaína se incrementaban cuando el cliente lo demanda, y presentaban ciertos beneficios para las mujeres, como ocuparse con un mayor número de clientes y el incremento de los i…

Mujeres dependientes de alcohol o cocaína: un estudio comparativo desde una perspectiva cualitativa

2008

-josefa.gomez@uv.es Objetivo: Realizar un análisis comparativo de los comportamientos sociales de las mujeres alcohólicas respecto a las cocainómanas. Material y métodos: Se han estudiado seis mujeres alcohólicas y seis mujeres cocainómanas en tratamiento ambulatorio, mediante la técnica del relato de vida. La información fue analizada utilizando la Grounded Theory. Resultados: Las mujeres alcohólicas adquieren la dependencia a través de un consumo progresivo, mientras que las cocainómanas se inician a partir de un hecho concreto, relacionándolo con la pareja consumidora y/o la búsqueda de placer. Un estigma social, que se manifiesta en las mujeres adictas, es el relacionado con el incumpli…

Occurrence of illicit drugs in two wastewater treatment plants in the South of Italy

2017

In this study the occurrence and the behavior of illicit drugs and their metabolites have been investigated for two wastewater treatment plants (WWTPs) (namely, WWTP-1 and WWTP-2) located in Sicily (island of Italy). Samples were analyzed for methamphetamine, cocaine (COC), 3,4-methylenedioxymethamphetamine (MDMA), methadone (METH), 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP), 3,4-methylenedioxy amphetamine (MDA); 3,4-methylenedioxy ethylamphetamine (MDEA), 11-nor-9-carboxy-Δ9-tetrahydrocannabinol (THC-COOH) and Benzoylecgonine (BEG). The BEG, COC, MOR and THC-COOH were found at the highest concentration in both WWTPs. The Wastewater-based epidemiology calculation for BEG, COC…
