Haloperidol does not antagonize the effects of stress on aggressive behaviour in mice.
1990
The possibility that antipsychotic drugs antagonize the behavioural effects of stress on agonistic behaviour has been explored. Male mice of the OF.1 strain were subjected to the following treatments: 1) Immobilization stress (ten or twenty minutes in duration), 2) haloperidol (three doses) and 3) immobilization stress (ten minutes) plus haloperidol. Individually housed experimental animals confronted standard opponents (anosmic animals) in ten-minute encounters in a neutral cage. Encounters were videotaped and behaviour evaluated, assigning times allocated by subjects to eleven broad behavioural categories. The data show that stress markedly decreases attack behaviour, but haloperidol does…

Acute behavioural and neurotoxic effects of MDMA plus cocaine in adolescent mice.
2008
The poly-drug pattern is the most common among those observed in MDMA users, with cocaine being a frequently associated drug. This study evaluates the acute effects of MDMA (5, 10 and 20 mg/kg), alone or in combination with cocaine (25 mg/kg), on motor activity, anxiety (elevated plus maze and social interaction test), memory and brain monoamines in adolescent mice, Both drugs, administered alone or concurrently, produced hyperactivity and a decrease in social contacts. However, an anxiolytic effect, studied by means of the elevated plus maze and expressed as an increase in the time spent on the open arms, was observed only in those animals treated with cocaine and MDMA. The passive avoidan…
Ontogenetic trophic segregation between two threatened smooth-hound sharks in the Central Mediterranean Sea
2020
AbstractElasmobranchs are among the species most threatened by overfishing and a large body of evidence reports their decline around the world. As they are large predators occupying the highest levels of marine food webs, their removal can alter the trophic web dynamic through predatory release effects and trophic cascade. Suitable management of threatened shark species requires a good understanding of their behaviour and feeding ecology. In this study we provide one of the first assessments of the trophic ecology of the “vulnerable” smooth-hounds Mustelus mustelus and M. punctulatus in the Central Mediterranean Sea, based on stomach contents and stable isotope analyses. Ontogenetic diet ch…
LGB´s Arts Affinity: An Empirical Study of Theater Audiences Based on Motivations
2021
The extended belief of gay people being more creative and showing higher interest toward arts lacks robust empirical support. The pioneer study on this issue highlighted that LGB´s arts participation was mostly explained by demographic factors such as level of studies, residence and family situation, which suggests that differences due to sexual orientation tend to fade. In this paper, we put forward the hypothesis that sexual orientation influences motivations to participate, which emphasizes their role and heterogeneity. To do so, we conducted a survey on participants at an alternative performing arts festival collecting information on socio-demographics, including sexual orientation, mot…
The antidepressant-like effect of tDCS in mice: A behavioral and neurobiological characterization
2017
Abtract Background Transcranial direct current stimulation (tDCS) is a non-invasive method increasingly popular for the treatment of several brain disorders, such as major depression. Despite great enthusiasm and promising results, some studies report discrepant findings and no consensus exists for the clinical use of tDCS. Objective The present study aims to (i) determine the most effective stimulation parameters to optimize antidepressant-like effect of tDCS in the forced-swim test in mice and (ii) identify brain regions recruited by tDCS and possibly involved in its behavioral effect using Fos immunohistochemistry. Results We reported that tDCS induced long-lasting antidepressant-like ef…

Learning to Eat Vegetables in Early Life: The Role of Timing, Age and Individual Eating Traits
2014
Vegetable intake is generally low among children, who appear to be especially fussy during the pre-school years. Repeated exposure is known to enhance intake of a novel vegetable in early life but individual differences in response to familiarisation have emerged from recent studies. In order to understand the factors which predict different responses to repeated exposure, data from the same experiment conducted in three groups of children from three countries (n = 332) aged 4-38 m (18.9 +/- 9.9 m) were combined and modelled. During the intervention period each child was given between 5 and 10 exposures to a novel vegetable (artichoke puree) in one of three versions (basic, sweet or added e…
Alcohol-impaired Walking in 16 Countries: A Theory-Based Investigation.
2021
Alcohol is a global risk factor for road trauma. Although drink driving has received most of the scholarly attention, there is growing evidence of the risks of alcohol-impaired walking. Alcohol-impaired pedestrians are over-represented in fatal crashes compared to non-impaired pedestrians. Additionally, empirical evidence shows that alcohol intoxication impairs road-crossing judgements. Besides some limited early research, much is unknown about the global prevalence and determinants of alcohol-impaired walking. Understanding alcohol-impaired walking will support health promotion initiatives and injury prevention. The present investigation has three aims: (1) compare the prevalence of alcoho…
