BACKGROUND The impact of variation of Epstein-Barr virus (EBV) antibody titers before the development of nasopharyngeal carcinoma (NPC) is still unclear. We analyzed the fluctuations of antibodies against EBV before histopathological diagnosis to assess the risk of NPC and aimed to provide a reliable basis for screening in high risk populations. METHODS This study was based on a population-ba...

UNLABELLED Undifferentiated nasopharyngeal carcinoma (NPC) has a 100% association with Epstein-Barr virus (EBV). However, only three EBV genomes isolated from NPC patients have been sequenced to date, and the role of EBV genomic variations in the pathogenesis of NPC is unclear. We sought to obtain the sequences of EBV genomes in multiple NPC biopsy specimens in the same geographic location in o...

Renewable systems influence the process of supplying domestic electricity demands. It will be useful to replace the conventional energy generation system by renewable energy sources since the uncontrolled use of fossil fuels is accompanied by global warming and environmental hazards, in addition to the danger of their depletion, and because most of the energy derived from these fuels are used i...

PURPOSE To identify the novel gene signatures and molecular markers of nasopharyngeal carcinoma (NPC) by integrated bioinformatics analysis of multiple gene expression profiling datasets. EXPERIMENTAL DESIGN Seven published gene expression profiling studies and one of our unpublished works were reanalyzed to identify the common significantly dysregulated (CSD) genes in NPC. Overrepresentation...

All materials enter or exit the cell nucleus through nuclear pore complexes (NPCs), efficient transport devices that combine high selectivity and throughput. NPC-associated proteins containing phenylalanine-glycine repeats (FG nups) have large, flexible, unstructured proteinaceous regions, and line the NPC. A central feature of NPC-mediated transport is the binding of cargo-carrying soluble tra...

AIM The aim of this study is to assess the morphology of nasopalatine canal (NPC) with cone beam computed tomography (CBCT). MATERIALS AND METHODS A total of 460 subjects of both genders were subjected to CBCT with NewTom machine, and sagittal and coronal sections were used for evaluation of the shape of NPC and width of buccal cortical plate. Types of NPC were also assessed. RESULTS Of 460...

BACKGROUND Nasopharyngeal carcinoma (NPC) has known as a highly distinct kind of head and neck cancer. This distinction has been due to its clinical presentation, epidemiology, outcome, and treatment. There have not been any reports of epidemiological analysis of NPC in Iran. This study has evaluated the incidence rates and trends of nasopharyngeal carcinoma in the Iranian population during 200...

Nasopharyngeal carcinoma (NPC) is an epithelial malignancy of the head and neck and the incidence is higher in Southeast Asia. Tetrandrine (TET) is a bisbenzylisoquinoline alkaloid, a natural product, and exhibits biological activities including action against many human cancer cell lines. However, the molecular mechanism of TET-induced cell apoptosis in human NPC cells is still unclear. In the...

Nasopharyngeal carcinoma (NPC) is the most commonly diagnosed head and neck malignancy and is prevalent worldwide. Previous studies have demonstrated the antitumor properties of cepharanthine hydrochloride (CH) in several human cancer cells. However, the action of CH in NPC cells has yet to be determined. In the present study, we investigated the effects of CH in human NPC cell lines including ...

BACKGROUND A case-control study was conducted to evaluate the role of adult diet on nasopharyngeal carcinoma (NPC) in Taiwan. METHODS A total of 375 incident NPC cases and 327 controls matched to the cases on sex, age, and residence were recruited between July 1991 and December 1994. A structured questionnaire inquiring complete dietary history, socio-demographic characteristics, and other po...
