Behavioural and neurochemical effects after repeated administration of N-ethylpentylone (ephylone) in mice
2022
N-ethyl-pentylone (NEP), also known as "ephylone" and N-ethylnorpentylone, has been identified as one of the most recent novel psychostimulants to emerge into the illicit drug market and it has been associated with some intoxications and even fatalities. However, little is known about the consequences of its repeated consumption as well as the role of the monoaminergic system in such consequences. Thus, the aim of our study was to investigate the neurochemical profile and the behavioural effects after both acute and repeated NEP exposure. Male OF1 mice were acutely (1, 3, 10 mg/kg, i.p.) or repeatedly (1, 3, 10 mg/kg, i.p., 5 days, twice/day) exposed to NEP, and anxiety-like behaviour, aggr…
Lethal and behavioural effects of a green insecticide against an invasive polyphagous fruit fly pest and its safety to mammals
2021
Abstract Plant essential oil-based insecticides, with special reference to those that may be obtained from largely available biomasses, represent a valuable tool for Integrated Pest Management. However, the sublethal effects and the potential effects on aggressive insect traits of these green insecticides are understudied. Herein, the lethal and sub-lethal effects of the carlina oxide, constituting more than 97% of the whole Carlina acaulis (Asteraceae) root essential oil (EO), were determined against an invasive polyphagous tephritid pest, Ceratitis capitata (medfly). The carlina oxide was formulated in a mucilaginous solution containing carboxymethylcellulose sodium salt, sucrose, and hyd…
La agresividad auto y heteroevaluada: variables implicadas [Self and heteroinform aggression: involved variables]
2006
The infantile and juvenile aggressiveness is considered to be a complex phenomenon, with multiple factors that contribute to different aggressive manifestations. For all this, this phenomenon has been an object of many investigations, which have the aim to understand the basic mechanisms that cause and regulate these behaviors (Eron y Huesmann, 1984; Caprara y Pastorelli, 1989, 1993, 1996; Bandura, Barbaranelli, Caprara, Pastorelli, y Regalia 2001; Caprara, Barbaranelli, Pastorelli, Bandura, y Zimbardo, 2001). This work tries to analyze the aggressive behavior and the implied processes. We have evaluated the emotional instability (IE, Caprara & Pastorelli, 1993; Del Barrio, Moreno & Lopez, …
Disposition-Content Congruency in Adolescents’ Alcohol-Related Social Media (Self-) Effects: The Role of the Five-Factor Model
2019
Objective: Accumulating evidence indicates that social networking sites play an increasingly important role in young people’s drinking behavior. The present study adds to this research by assessing the conditionality of the relationships between exposure to and self-sharing of alcohol-related content on social media and adolescents’ drinking behavior. Specifically, the moderating role of the five-factor model of personality is determined. Method: A cross-sectional survey study was conducted among 866 mid-adolescents (Msubsample = 14.85 years, SD = 0.71, 57.5% girls). Polynomial regression analysis with response surface modeling was used to test the interactions. Results: Exposure, but not s…
Antecedents of trait aggressiveness among sports students
2016
In light of the speed increase of aggressive episodes and disorderly incidents in sporting contexts both on and off the field of play, psychologists’ interest has been focused on normative standards regarding socio-moral interaction such as sportspersonship and fair play, as well as on those intra and interpersonal factors influencing aggressiveness. The current research aimed at pinpointing the extent to which self-determined motivation and trait self-control influence aggressiveness considered as a personality trait. 448 students (M = 240, F = 208; M age = 23,04, SD = 6,65) enrolled in Italian Faculties of Sport and practicing competitive sports filled out a questionnaire composed by: the…

Autisma iezīmes, agresivitāte un vecāku – bērnu mijiedarbība bērniem vecumā no 22 līdz 30 mēnešiem
2018
Pētījuma ietvaros tika apzinātas sakarības starp autiskā spektra iezīmēm, agresivitāti un audzināšanas pieejām vecāku-bērnu mijiedarbībā bērniem 22-30 mēnešu vecumā, un noskaidrots, vai pastāv statistiski nozīmīgas atšķirības agresivitātes rādījumos bērniem ar un bez autiskā spektra traucējumu iezīmēm. Pētāmo izlase: 115 bērni vecumā no 22 līdz 30 mēnešiem, apakšizlasē 18 bērni.

Externalizing Behaviors and Cigarette Smoking as Predictors for Use of Illicit Drugs: A Longitudinal Study Among Finnish Adolescent Twins
2010
We examined whether externalizing problem behaviors (hyperactivity–impulsivity, aggressiveness, and inattention) predict illicit drug use independently, or whether their associations with drug use are mediated through cigarette smoking. We used a prospective longitudinal design within theFinnTwin12-17study among Finnish adolescents with baseline at age 12 and follow-up surveys at ages 14 and 17. Path models were conducted withMplusand included 1992 boys and 2123 girls. The outcome was self-reported ever use of cannabis or other illicit drugs at age 17. The predictors were: externalizing behaviors (hyperactivity–impulsivity, aggressiveness, and inattention) assessed by teachers and parents (…
