Despite recent research suggesting that relationally aggressive behaviors occur frequently and may lead to physically aggressive actions within urban school settings, there has been little prior research to develop and evaluate relational aggression prevention efforts within the urban schools. The current article describes the development and preliminary evaluation of the Preventing Relational ...

Introduction: Agonistic behaviors help to ensure survival, provide advantage in competition, and communicate social status. The resident-intruder paradigm, an animal model based on male intraspecific confrontations, can be an ethologically relevant tool to investigate the neurobiology of aggressive behavior. Objectives: To examine behavioral and neurobiological mechanisms of aggressive behavi...

The present study examined the relations between aggressive fantasies, thought control strategies and aggressive behaviour in a sample of non-clinical female participants (N = 72). First, the nature and prevalence of aggressive fantasies and thought control strategies were examined. Then, the relation between these constructs and aggressive behaviour was studied by means of correlations and reg...

The clinical, radiological and pathological features of two cases of an osteogenic tumour with long survival are described. The tumours have the histological pattern of benign osteoblastoma with other more cellular and aggressive features suggestive of a low grade osteosarcoma. They are locally invasive but the absence of metastases indicates that separation from both entities is justified clin...

Background & Objective: Basal cell carcinoma (BCC) is a common skin cancer arising from the basal layer of the epidermis and its appendages. They are locally invasive, aggressive, and destructive of skin and the surrounding structures. β-Catenin is a multifunctional protein located to the intracellular side of the cytoplasmic membrane coded by the CTNNB1 gene, which maps to chr...

objective: assessment of subgingival human cytomegalovirus (hcmv) and epstein barr virus (ebv-1) in subjects with aggressive periodontitis. materials and methods: samples were obtained from plaques formed in subgingival regions of 26 aggressive periodontitis patients. all specimens were submitted to polymerase chain reaction in order to detect hcmv and ebv-1. results: hcmv and ebv-1 were observ...

background: aggressive fibromatosis is a rare benign tumor with no potential for metastasis; however, its aggressive nature causes treatment failure and episodes of recurrence. there is no report from iran about the treatment of this tumor, and all published articles are single-case reports, therefore in this study, we report our experience from two of the largest referral centers of the south ...

background and aims. the aim of this study was to compare the effectiveness of adjunctive photodynamic therapy (pdt) in the treatment of aggressive periodontitis. materials and methods. a total of 24 patients with clinical diagnosis of aggressive periodontitis received scaling and root planing (srp) for periodontal treatment. in a split-mouth design study, the teeth of one quadrant of each arch...

Aggressive behavior is a common reaction in humans after an interpersonal provocation, but little is known about the underlying brain mechanisms. The present study analyzed oscillatory brain activity while participants were involved in an aggressive interaction to examine the neural processes subserving the associated decision and evaluation processes. Participants were selected from a larger s...
