BACKGROUND Understanding the size and shape of radiofrequency lesions is important to reduce side effects when applied to patients. OBJECTIVES To investigate the radiofrequency lesions produced by the application of the Tew electrode for different temperatures and times. METHODS The white from a fresh hen's egg was placed in a rectangular glass container and warmed to 37 °C. After immersion...

Normal monkeys and monkeys with lesions of the hippocampal formation and adjacent cortex (the H+ lesion) were trained on the delayed nonmatching to sample (DNMS) task with a delay of 0.5 s between the sample and the choice. The animals with H+ lesions learned the task normally at this short delay and also exhibited the same pattern of response latencies as normal monkeys. This finding contrasts...

The study objective was to estimate the pressure threshold (ED(05), effective dose, or in situ peak rarefactional pressure associated with 5% probability of lesions) of ultrasound (US)-induced lung hemorrhage as a function of pulse duration (PD) in adult rats. A total of 220 10- to 11-week-old 250-g female Sprague-Dawley rats (Harlan) were randomly divided into 20 ultrasonic exposure groups (10...

Objective(s) Studies have described immunomedulatory effects of sun exposure and ultraviolet radiation on infectious and neoplastic diseases. Here the effect of exposure to low potency radiation of sun on the course of leishmaniasis in mice was studied. Materials and Methods Fifteen BALB/c mice were exposed to suberythemogenic doses of sun (mean 180 mJ/cm2/day of UVB) 2 months before and 4 m...

background and aims. reactive hyperplastic lesions of the oral connective tissue are associated with injuries of soft tissue and have high prevalence rates and different involvement patterns in different parts of the world. the aim of this study was to analyze demographic data of a university department. materials and methods. patient records of the department of oral pathology during a four-ye...

background: the clinical and pathological evaluation of oral lesions are very important in this field. the purpose of this study was to assess clinico- pathological agreement on 232 cases with oral lesion s.methods: the consecutive files of 232 patients with oral lesions from pathological laboratory archives of babol dental faculty and shahid beheshti hospital were reviewed and the data include...

This report describes the first isolation of Schizophyllum commune from a granulomatous lesion on the neck of a dog. The biopsy specimen from the lesion disclosed granulomatous inflammation with branching fungal hyphae without clamp connections. The clinical isolate was identified as S. commune by mycological examination and analysis of ribosomal DNA sequences.

Congenital gingival granular cell tumor is a rare benign lesion of uncertain origin, which has been found only in newborn infants. This article describes one such case. Our immunohistochemical study employing antibodies against S-100 protein, epithelial membrane antigen, carcinoembryonic antigen, wide-spectrum keratin, desmin and vimentin yielded data supporting the theory of a mesenchymal cell...

Purpose: In this study, unlike the previous studies, and Power Doppler vocal fremitus test (PDVFT) is utilized and is evaluated in subcategories to assess its role in the differentiation of benign and malignant lesions. Materials and Methods Thorough the 161 lesions of 147 patients are included in this prospective study. During PDVFT, it is determined that eight different fremitus patterns have...
