Inflammation (or inflammatory reaction) is the response to body aggression by a pathogen agent, an allergen, a toxic compound, a tissue lesion, etc.[...]

The dopamine D3 antagonist U-99194A maleate increases social behaviors of isolation-induced aggressive male mice.

1999

Rationale: Blockade of D1/D2 dopamine receptors produce an antiaggressive action commonly associated with an impairment of other motor behaviors. The D3 receptor seems to present opposite actions to the D1 and D2, since the blockade of this receptor produces stimulation of motor activity which has been associated with an increase in dopamine neurotransmission. Objective: In this work, the action of the dopamine D3 antagonist U-99194a maleate on locomotor activity and in a social interaction test in male mice was evaluated. Methods: Animals isolated during 30 days were treated with U-99194a maleate (20–40 mg/kg) or saline and locomotor activity was measured 20 min after drug administration. …

Memantine does not block antiaggressive effects of morphine in mice.

2002

The action of the noncompetitive N-methyl-D-aspartate (NMDA) receptor blocker memantine (5, 10, 20 and 40 mg/kg) was evaluated during social encounters in mice. Although a dose-dependent increase in locomotion was observed, only with the highest dose did it reach statistical significance. Aggressive behavior was decreased with 20 and 40 mg/kg of memantine, social contacts being increased only with 20 mg/kg. Subsequently, the effect of these memantine doses on the antiaggressive actions of morphine (10 mg/kg) was evaluated. None of the doses affected the antiaggressive action of morphine. As memantine administration produced an antiaggressive effect only at doses that affected locomotion, it…

The linguistic representation of gender violence in (written) media discourse

2014

‘Woman’ is a key social actor, and a central conceptualization, in the construction of media discourses of gender-based violence. Scholarly research at the turn of the 21st century (Bengoechea 2000; Lledó 2002; Fernández Díaz 2003; Jorge 2004) showed that in the Spanish press, media discourses had a tendency to naturalize male aggression not as violence but as part of the (private) sexual arrangement between the sexes. In this paper we explore the treatment of the phrasemujer maltratada(EN ‘battered woman’) in intimate partner violence newspaper articles from 2005 to 2010. Our aims are: (i) to account for the discursive representation of violence against women (VAW) in Spanish contemporary …

Mapping Brain Response to Social Stress in Rodents With c-fos Expression: A Review

2002

Social defeat is an important event in the life of many animals, and forms part of the process of social control. Adapting to social defeat is thus an intrinsic part of social "homeostasis", and mal-adaptation may have pathological sequelae. Experimental models of social defeat (e.g. inter-male aggression) have existed for many years. However, very few studies have investigated the changes in brain activity in male animals exposed to the social stress of being defeated by another conspecific male, and in all these studies the expression of the immediate-early gene c-fos has been used as the marker of neuronal activity. In general, the results obtained inform that many areas of the brain, es…

Differences in Inhibitory Control between Impulsive and Premeditated Aggression in Juvenile Inmates

2017

Inhibitory control dysfunction was considered a universal characteristic of violent offenders. The aim of this study was to examine differences in inhibitory control between two subtypes of violent youth; those displaying predominantly impulsive and those presenting predominantly premeditated aggression (PM). Forty-four juvenile offenders, defined on the basis of the Procedures for the Classification of Aggressive/Violent Acts (Stanford and Barratt, 2001) participated (N = 23: impulsive; N = 21 premeditated). A visual Go/NoGo task was used to compare behavioral responses and event-related potentials (ERPs) between groups. The task contained two letters (W and M), W was the Go stimulus and M…

Mothers who killed or attempted to kill their child: life circumstances, childhood abuse, and types of killing.

1999

The objectives of the present study were to examine the life circumstances, childhood abuse, and types of homicidal acts of 48 mothers who killed/attempted to kill their children) under age 12 between 1970-96 in Finland. Data on the mothers’ life stresses, psychological problems, and childhood abuse were collected from mental state examination (MSE) reports. The cases were divided into 15 neonaticides and 33 mothers who killed an older child. Childhood abuse was documented in 63% of the mothers’ MSE reports. Qualitative analysis identified neonaticides, joint homicide-suicide attempts, impulsive aggression, psychotic acts, postpartum depression, and abusive acts. Nonlinear principal compone…

Antisocial Behavior in Childhood and Adolescence

2001

Antisocial behavior is a broad construct that encompasses not only delinquency and crime, but also disruptive behavior of children, such as aggression, below the age of criminal responsibility. Legal, clinical, and developmental definitions of antisocial behavior have different foci. Development of antisocial behavior is studied using a longitudinal design. A high association has been obtained between aggression and hyperactivity in childhood and later antisocial behavior particularly in life-course-persistent offenders. The adolescence-limited pattern of offending is less strongly associated with disruptive behavior in childhood. Individual differences in aggression emerge early in life, a…
