This study aimed to quantify dosimetric effects of weight loss for nasopharyngeal carcinoma (NPC) treated with intensity-modulated radiation therapy (IMRT). Overall, 25 patients with NPC treated with IMRT were enrolled. We simulated weight loss during IMRT on the computer. Weight loss model was based on the planning computed tomography (CT) images. The(More)
PURPOSE Our aim was to evaluate the volumetric and dosimetric changes of target volumes and organs at risk (OARs) during intensity-modulated radiation therapy (IMRT) for locoregionally advanced nasopharyngeal carcinoma (NPC) and the necessity of replanning. MATERIALS AND METHODS Twenty locoregionally advanced NPC patients treated by concurrent(More)
The Middle East respiratory syndrome coronavirus (MERS-CoV) closely resembled severe acute respiratory syndrome coronavirus (SARS-CoV) in disease manifestation as rapidly progressive acute pneumonia with multi-organ dysfunction. Using monocyte-derived-dendritic cells (Mo-DCs), we discovered fundamental discrepancies in the outcome of MERS-CoV- and(More)
Recent studies have identified olfactory ecto-mesenchymal stem cells (OE-MSCs) as a new type of resident stem cell in the olfactory lamina propria. However, it remains unclear whether OE-MSCs possess any immunoregulatory functions. In this study, we found that mouse OE-MSCs expressed higher transforming growth factor-beta and interleukin-10 levels than bone(More)
We have developed intelligent polymerized crystalline colloidal array (IPCCA) chemical-sensing materials for detection of Pb(2+) in high ionic-strength environments such as body fluids with a detection limit of <500 nmol L(-1) Pb(2+) (100 ppb). This IPCCA lead sensor consists of a mesoscopically periodic array of colloidal particles polymerized into an(More)
The protective potential of melatonin (MLT) in Parkinson's disease (PD) is the subject of considerable controversy. The purpose of the present study was to investigate serum MLT levels in unilateral 6-hydroxydopamine (6-OHDA) lesion rats and patients with PD. Blood samples were collected from rats at 10:00 am and from patients with PD and healthy subjects(More)
MicroRNAs (miRNAs) are a class of approximately 20-nucleotides single-stranded endogenous RNAs that regulate gene expression at the post-transcriptional level. miRNAs have recently been known to regulate cell proliferation, differentiation, and apoptosis. Fibrosis is the leading cause of organ dysfunction in diseases and results from an imbalance in the(More)
RATIONALE Heart valves develop from precursor structures called cardiac cushions, an endothelial-lined cardiac jelly that resides in the inner side of the heart tube. The cushions are then invaded by cells from different sources, undergo a series of complicated and poorly understood remodeling processes, and give rise to valves. Disruption of the fibroblast(More)
In the present study, double fluorescence staining combined with confocal laser scanning microscopy analysis were used to examine the effects of melatonin on ischemia-induced neuronal DNA strand breaks and its possible mechanisms in a transient middle cerebral artery (MCA) occlusion model. Results showed that melatonin dose-dependently reduced infarct areas(More)
To investigate the associations of serum levels of intercellular adhesion molecule-1 (ICAM1) and the pro-inflammatory cytokine interleukin-6 (IL-6) with migraine and migraine subtypes, and to study their correlation with each other in this condition. We used enzyme-linked immunosorbent assay to measure serum levels of ICAM1 and IL-6 in 103 migraine patients(More)
