Anomalies of the epidermal growth factor receptor (EGFR) gene, including amplification, rearrangement, and overexpression, have been reported in malignant human gliomas in vivo. In vitro glioma cell lines coexpress EGFR and at least one of its ligands, transforming growth factor alpha, suggesting the existence of an autocrine growth stimulatory loop. We have studied the tumor tissue from 62 hum...
Classical hemophilia results from a defect of the intrinsic tenase complex, the main factor X (FX) activator. Binding of factor VIIa to tissue factor triggers coagulation, but little amplification of thrombin production occurs. Handling of hemophilia by injection of the deficient or missing (thus foreign) factor often causes immunological complications. Several strategies have been designed to ...
Objectives: Older adults show many difficulties of speech perception in noisy situations due to peripheral and central auditory impairments, and cognitive dysfunctions. One of the most common rehabilitative procedures for older adults with hearing loss is amplification. However, there is some evidence of dissatisfaction of amplification in older adults. Methods & Materials: We assessed cogni...
PURPOSE The purpose of this study is to investigate the prognostic significance of SOX2 gene amplification and expression in patients with American Joint Committee on Cancer stage III lung squamous cell carcinoma (SCC) who underwent surgery followed by adjuvant radiotherapy. MATERIALS AND METHODS Pathological specimens were obtained from 33 patients with stage III lung SCC treated with surger...
Background & Aims:Thromboembolism is an acute cardiovascular disease that ranges from clinically unimportant to massive embolism. Both acquired and hereditary risk factors contribute to the disease. We aimed to determine the prevalence of two hereditary predisposing factor of the disease, prothrombin G20210A and factor V Leiden (G1691A) polymorphisms, in Kerman population.<br /...
OBJECTIVES The transcription factor SOX2 (3q26.3-q27) is an embryonic stem cell factor contributing to the induction of pluripotency in terminally differentiated somatic cells. Recently, amplification of the SOX2 gene locus has been described in squamous cell carcinoma (SCC) of different organ sites. Aim of this study was to investigate amplification and expression status of SOX2 in sinonasal c...
In a subset of lung adenocarcinomas, the epidermal growth factor receptor (EGFR) is activated by kinase domain mutations and/or gene amplification, but the interaction between the two types of abnormalities is complex and unclear. For this study, we selected 99 consecutive never-smoking women of East Asian origin with lung adenocarcinomas that were characterized by histologic subtype. We analyz...
