basal cell carcinoma (bcc) is currently the most common cutaneous cancer found in humans. although it generally shows a relatively benign course (bccl), some cases show aggressive behavior (bcc2). until recently, traditional histologic diagnostic criteria have failed to discriminate unequivocally between bcc 1 and bcc2. in this study we selected 50 cases of bcc and categorized them into two gro...

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...

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 & 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...

Background and Objective: Clinical behavior of basal cell carcinoma (BCC) is known to be different according to histological growth pattern and basosquamous cell carcinomas (BSC) are known with their aggressive behavior and metastatic capacity. In this study, we evaluated bcl-2 and cyclin D1 expressions in BCC and BSC cases comparatively, to explore their predictive value on the aggres...
