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 non-ag...

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...

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...

PURPOSE The purpose is to investigate whether aggressive basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) differ from nonaggressive BCC and SCC with respect to the p53 mutation spectrum and whether specific mutations can serve as prognostic indicators of tumor aggressiveness. EXPERIMENTAL DESIGN We analyzed 342 tissues from patients with aggressive and nonaggressive BCCs and SCCs ...

By identifying aggressive cutaneous squamous cell carcinoma (cSCC) in patients who are at high risk for recurrences or second primaries after resection, intensive surveillance and therapy may decrease morbidity and mortality. We investigated the role of nuclear morphometry (karyometry) in differentiating between aggressive and nonaggressive cSCC. We retrospectively analyzed cSCC lesions from 40...

The current study examined the best friendships of aggressive and nonaggressive boys (N = 96 boys, 48 dyads, mean age = 10.6 years). Friends completed self-report measures of friendship quality, and their interactions were observed in situations that required conflict management and provided opportunities for rule-breaking behavior. Although there were no differences in boys' self-reports of fr...

OBJECTIVE This study was designed to assess central serotonergic (5-HT) function in aggressive and nonaggressive boys with attention deficit hyperactivity disorder. METHOD Prolactin response to a challenge dose of the 5-HT agonist d,l-fenfluramine was assessed in 25 7-11-year-old boys with attention deficit hyperactivity disorder who were divided into aggressive and nonaggressive subgroups. I...

The attributions and responses of aggressive and nonaggressive boys to ambiguously intended actions of friends and nonfriends were examined. Thirty-seven aggressive and 37 nonaggressive thirdand fifth-grade boys were presented with descriptions of encounters between peers in which one child experienced a negative outcome as the result of the ambiguously intended actions of another. Neither aggr...
