calcifying odontogenic cyst (coc) is a unique odontogenic lesion with combined features of a cyst and neoplasm.  this lesion shows a great diversity in its clinicopathological behavior.  it may become aggressive and rarely malignant.  this case is an aggressive coc of the maxilla in a young male patient which recurred after several radical surgical excisions.  eventually invading the cranium, t...

introduction: giant cell lesions of the bone comprise a group of jaw bone pathologies. different pathogeneses such as reactive, vascular or neoplastic have been proposed for these lesions. in addition, differentiating between aggressive and nonaggressive central giant cell granuloma (cgcg) of the jaws based on histopathologic features is still impossible and due to different treatment protocols...

background: aggressive personality changes are one of the most prevalent neuropsychiatric disorders after traumatic brain injury (tbi). it may lead to serious impairments in social relations and affect rehabilitation process. present research was performed to identify the determinant factors of personality change of aggressive characteristics after tbi. methods: 238 tbi patients (195 men and 43...

We have been made aware that the estimate of individual repeatability that we used in our study (i.e. the intraclass correlation coefficient) overestimates repeatability, and that calculating repeatability using the analysis of variance-based method, as described by Lessells & Boag [1]), is a more appropriate estimate. Consequently, we have recalculated repeatability using this more appropriate...

The present study aimed to investigate the longitudinal influence of physical education classes, extracurricular sports activities, and leisure satisfaction on aggressive behavior among South Korean adolescents. Data were drawn from the Korea Youth Panel Survey. We used latent growth curve modeling to explain the growth trajectory of adolescent aggressive behaviors and a multi-group analysis to...

Repeatable behavioural traits ('personality') have been shown to covary with fitness, but it remains poorly understood how such behaviour-fitness relationships come about. We applied a multivariate approach to reveal the mechanistic pathways by which variation in exploratory and aggressive behaviour is translated into variation in reproductive success in a natural population of blue tits, Cyani...

Research is needed to validate lesions recorded at meat inspection as indicators of pig welfare on farm. The aims were to determine the influence of mixing pigs on carcass lesions and to establish whether such lesions correlate with pig behaviour and lesions scored on farm. Aggressive and mounting behaviour of pigs in three single sex pens was recorded on Day -5, -2, and -1 relative to slaughte...

Relational aggression is a form of covert or indirect aggression or bullying in which harm is caused through damage to relationships or social status within a group, rather than through physical violence. We compare findings from empirical research into relational aggression with the depictions, interpretations and interventions described in trade-books and popular media dealing with that same ...

Bullying is characterized by repeated physical or verbal interactions that are meant to be hostile, cause distress, and involve a power differential between bully and victim (1). While certain characteristics of bullying distinguish it from other forms of aggressive behaviour (for example, its repetitive nature and power differential), bullying can occur in many forms across the lifespan, from ...
