A recent study has suggested that aggressive (AGG) and non-aggressive, rule-breaking (RB) antisocial behavior evidence differential and subtype-specific patterns of genetic expression during development. Namely, although genetic influences on RB increase dramatically during early- to mid-adolescence, genetic influences on AGG appear to remain stable. As no other study has examined age-related c...

Ossifying fibromas form a part of the spectrum of fibro-osseous lesions of the jaws. They are rare, benign, nonaggressive tumors that are commonly seen in head and neck region. Fibro-osseous lesions are a diverse group of processes that are characterized by replacement of normal bone by fibrous tissue containing a newly formed mineralized product [1]. Ossifying fibroma is a rare, destructive, d...

Although a role for oncogenic KIT in driving mast cell disease is clear, the mechanisms driving the multiple phenotypic and clinical manifestations of this disorder are not well elucidated. We now show, using a large cohort of mastocytosis patients, including an almost equal number of aggressive and nonaggressive cases of systemic mastocytosis, that in contrast to the oncogenic KITD816V, TET2 m...

The results of three experiments demonstrate that physically aggressive displays are part of men's cultural script for restoring threatened gender status. In Studies 1 and 2, challenges to men's gender status elicited heightened physically aggressive displays, including punching a pad with greater force and selecting an aggressive boxing activity over a nonaggressive puzzle activity. Study 3 es...

A meta-analytic review was conducted to explain divergent findings on the relation between children's aggressive behavior and hostile attribution of intent to peers. Forty-one studies with 6,017 participants were included in the analysis. Ten studies concerned representative samples from the general population, 24 studies compared nonaggressive to extremely aggressive nonreferred samples, and 7...

In hamsters, adolescent anabolic-androgenic steroid (AAS) exposure facilitates offensive aggression, in part by altering the development and activity of anterior hypothalamic arginine vasopressin (AH-AVP). This study assessed whether these effects were lasting by examining aggression and AH-AVP during AAS withdrawal. Adolescent hamsters administered AAS were tested as adults for aggression at 1...

Long-term effects of multisensory stimulation were assessed using a "Snoezelen" room on older residents with dementia. Thirty patients were randomly assigned to 3 groups: multisensory stimulation environment (MSSE) group, individualized activities (activity) group, and control group. The MSSE and activity groups participated in two 30-minute weekly individualized intervention sessions over 16 w...

Ninety-nine 2-year-olds, out of a larger sample of 474 children, were classified as high (n = 49) or low (n = 50) in externalizing (aggressive/destructive) behaviors based on maternal reports assessed twice across a 2-month period. During a laboratory assessment, these toddlers participated in two empathy-eliciting tasks, from which affective, behavioral, and physiological measures were derived...

The aim of the present study was to examine the priming effects of violent movies and aggressive words on implicit aggression by using modified STROOP task. 190 adolescents participated in this study, with 95 assigned to non-violent movie group and 95 assigned to violent movie group. The results showed that no significant difference was found in the main affect of Movie Type, but it revealed si...

To identify Nicotiana tabacum genes involved in resistance and susceptibility to the phytopathogenic fungus Rhizoctonia solani, transcripts were generated (by subtractive libraries), which were differentially expressed in each interaction. This enabled isolation of a gene coding for a protein kinase that becomes silent during the susceptibility interaction and is activated during resistance. Th...
