The purpose of this investigation was to determine the interrelationships of the various sexual and aggressive behaviors exhibited by Hereford bulls in sexual performance (serving capacity) tests and to determine the extent to which these interrelationships change with age (maturity). Correlation matrices were constructed for the frequencies of sexual and aggressive behaviors exhibited by two g...

Reactive aggression following provocation is a frequent form of human social behavior. The neural basis of reactive aggression, especially its control, remains poorly understood, however. We conducted an event-related potential (ERP) study using a competitive reaction time task that elicits aggression through provocation. Participants were selected from a larger sample because of extreme scores...

Even though neurofibromatosis ( NF) is not a rare neurological disorder, but there is few studies regarding  the relationship between  NF and psychological disorders. A 14 year old girl with NF type 1 associated  with multiple cerebral lesions was admitted in psychiatric ward due to restlessness , hypertalktiveness aggressive behavior, and flight of idea. Psychiatric diagnosis, based on DSM IV ...

Aggressive angiomyxoma is a rare, slow-growing soft tissue tumor that usually arises in the pelvis and perineal regions of women in reproductive age, with a marked tendency to local recurrence. Because of its rarity, it is often initially misdiagnosed. Surgical resection is the main treatment modality of aggressive angiomyxoma. We describe a case of a vaginal aggressive angiomyxoma in a 47-year...

Recent advances in the study of affective-cognitive regulation of aggressive behavior suggest positive correlations between poor executive capacities (ECF) and dispositional negative reactivity (Posner & Rothbart, 2000). If the global assumption is correct what are the likely implications of predicted relation? The central issue in present research was to verify this assumption and examine ...

o bjectives: the aim of this study was to determine the cementum thickness in the first molars of patients with localized aggressive periodontitis (lap) compared to healthy individuals. materials and methods: this case-control study compared eight first molar teeth af-fected by lap with eight third molar teeth of healthy individuals. the teeth were dis- infected by immersion in 10% buffered for...

Argyrophilic staining of nucleolar organizer regions (AgNOR) has been considered to be useful in the diagnosis and prognostic evaluation of different cutaneous tumors. In order to evaluate the role of the AgNOR technique in discriminating aggressive from non-aggressive basal cell carcinoma (BCC), paraffin-embedded histologic sections from 30 cases of aggressive BCC (BCC2) and 30 cases of n...

effects of oral administration of testosterone and fluoxetine exposure on aggressive behavior of the fighting fish, betta splendens , were investigated. testosterone diluted in ethanol and sprayed on pre-weighted pellet to achieve concentrations of 0, 1, 2 and 4 mg/kg of hormone in food. two main behaviors were recorded: the time in front of mirror and duration of the gill flaring using a mirro...

background: periodontal subgingival pathogens affect local and systemic immune responses and initiate an acute phase systemic inflammatory response characterized by the release of c-reactive proteins (crps). this study has been carried out to evaluate the serum concentration of crps, which can be used as a marker of periodontal disease as well as a risk indicator for cardiovascular diseases. ma...
