The study searched for epidermal growth factor receptor (EGFR) gene amplification in hyperplastic glottis lesions. After classical pathohistological findings of hematoxylin-eosin (HE) slides and quantitative immunohistochemical (IHC) analysis, fluorescent in situ hybridization (FISH) was used on tissue microarrays of laryngeal hyperplastic tissue ranging from normal mucosa to abnormal and atypi...

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...

BACKGROUND Defining the arrhythmogenic substrate is essential for successful ablation of scar-related ventricular tachycardia. The visual characteristics of endocardial ischemic scar have not been described in vivo. The goal of this study was (1) to quantify the visual characteristics of normal tissue, scar border zone, and dense scar in vivo with the use of a novel endoscopic catheter that all...

The purpose of this study was to assess the impact of respiratory gating on tumor and normal tissue dosimetry in patients treated with SBRT for early stage non-small cell lung cancer (NSCLC). Twenty patients with stage I NSCLC were studied. Treatment planning was performed using four-dimensional computed tomography (4D CT) with free breathing (Plan I), near-end inhalation (Plan II), and near-en...

background and objective: different mechanisms may lead to the development of soft tissue tumor-like lesions in the oral cavity. many of these lesions can be identified as specific entities on the basis of their histopathological features and are divided into fibrous, vascular, and giant cell types. the purpose of this study was to establish the relative prevalence of the different histopatholo...

Abstract Background Amino acid PET radiopharmaceutical, 18F-fluciclovine, shows increased uptake in brain tumors relative to normal tissue and may be a useful tool for detecting recurrent metastases. Here, we report results from prospective pilot study evaluating the use of 18F-fluciclovine PET/CT distinguish radiation necrosis tumour progression among patients with metastases treated stereotac...

The equine stomach consists of two separate non-glandular and glandular sections. Despite the incidence most lesions in region, both parts are prone to lesions. In this study, 41 hybrid-native horses, including 24 stallions 17 mares, were examined over five years. total, 27 horses (65.85%) that sampled had lesions, erosion, granuloma, or on region stomach. Occurrence gastric erosive granulomato...
