Interleukin-8 (IL-8) is angiogeneic chemokine that plays a potential role in both development and progression of many human malignancies including nasopharyngeal carcinoma (NPC). Epstein- Barr virus (EBV) is recognized to be an important etiologic agent of NPC as the viral gene products are frequently detected in NPC tissue along with the elevation of antibody titre to the viral protein (VCA-p1...
Tumor suppressor p53 is a critical player in the fight against cancer as it controls the cell cycle check point, apoptotic pathways and genomic stability. It is known to be the most frequently mutated gene in a wide variety of human cancers. Single-nucleotide polymorphism of p53 at codon72 leading to substitution of proline (Pro) in place of arginine (Arg) has been identified as a risk factor f...
The present study was performed to identify the dysregulated microRNAs (miRNAs/miRs) and mRNAs, and enriched pathways involved in nasopharyngeal carcinoma (NPC) through the establishment of an miRNA‑mRNA‑pathways network. mRNA and miRNA expression profiles were collected from the European Molecular Biology Laboratory‑European Bioinformatics Institute. Differentially expressed genes and differen...
OBJECTIVES To compare HIV care quality provided by non-physician clinicians (NPC) and physicians. DESIGN Retrospective cohort study assessing the relationship between provider cadre and HIV care quality among non-pregnant adult patients initiating antiretroviral therapy (ART) in the national HIV care programme. METHODS Computerized medical records from patients initiating ART between July 2...
BACKGROUND Accumulating evidence has demonstrated that cyclooxygenase-2 (COX-2) is involved in head and neck cancers, especially in nasopharyngeal carcinoma (NPC). However, the association between COX-2 expression and lymph node metastasis in NPC remains uncertain. This systematic review and meta-analysis meta-analysis investigated the relationship between COX-2 expression and lymph node metast...
Many studies have suggested that folate-related one-carbon metabolism-related nutrients may play a role in certain cancer risks, but few studies have assessed their associations with the risk for nasopharyngeal carcinoma (NPC). In this study, we investigated the association between four folate-related one-carbon metabolism-related nutrients (folate, vitamin B6, vitamin B12 and methionine) and N...
BACKGROUND For patients with nasopharyngeal carcinoma (NPC) who undergo re-irradiation with intensity-modulated radiotherapy (IMRT), lethal nasopharyngeal necrosis (LNN) is a severe late adverse event. The purpose of this study was to identify risk factors for LNN and develop a model to predict LNN after radical re-irradiation with IMRT in patients with recurrent NPC. METHODS Patients who und...
Introduction: Nasopharyngeal carcinoma (NPC) is commonly known as a radiosensitive tumor with the initial good response to radiation. Despite the improved outcome in loco regional control by the introduction of combining treatment, modern radiotherapy techniques and enhanced imaging studies, local recurrent after primary treatment with rate ranges from 15-58% in 5 years, stil...
The authors propose a technique for reactive power compensation using powerful regenerative controlled-speed synchronous motor drive (SMD) based on three-level (3L) neutral point clamped (NPC) active front-end rectifier (AFE) and voltage source inverter (VSI). review of technical solutions showed that the limitations transmitted in system under consideration still have not been studied. paper p...
Penetration-aspiration is the most serious complication in patients with nasopharyngeal carcinoma (NPC) after radiotherapy. Radiotherapy has been shown to increase patient's survival rate and life expectancy but it showed side effects such as oropharyngeal dysphagia. It’s related morbidity mortality penetration-aspiration could progress aspiration pneumonia, sepsis, death if not treated properl...
