Photorealistic rendering is one of the oldest and most important research areas in computer graphics. More recently, the concept of non-photorealistic rendering has been proposed as an alternative with important advantages for numerous application areas. The popularity of non-photorealism can be mainly attributed to its simplicity, which could potentially(More)
Degenerative lumbar spinal stenosis (DLSS) can be treated by several surgical procedures. However, the choice of procedure and use of instrumentation remain controversial. In this retrospective study of 81 patients with DLSS, 43 patients received decompression and posterolateral fusion without instrumentation, and the surgery for 38 patients was(More)
We analyzed the clinical efficacy of the Zero-P implant (Synthes GmbH Switzerland, Oberdorf, Switzerland) in the treatment of single level cervical spondylotic myelopathy. The clinical data of 47 patients with single level cervical spondylotic myelopathy were retrospectively analyzed. Twenty-two patients were treated with a Zero-P implant (Group A) and 25(More)
Sacral chordoma is a vessel-rich and infiltrative tumor, but the fundamental knowledge of its biological behavior remains unknown. This study was designed to investigate the expression levels and contributions of vascular endothelial growth factor (VEGF) and matrix metalloproteinase-9 (MMP-9) in the angiogenesis and recurrence of sacral chordoma and their(More)
Increasing numbers of studies support the hypothesis that chordoma arises from notochordal cell rests, although the mechanism awaits further research. Brachyury is the first specific molecule linking chordoma with the notochord, and galectin-3 has been widely used as a marker of notochordal cells. We conducted a histological study of the expression of these(More)
Douchi is a type of Chinese traditional fermented food that is an important source of protein and is used in flavouring ingredients. The end product is affected by the microbial community present during fermentation, but exactly how microbes influence the fermentation process remains poorly understood. We used an Illumina MiSeq approach to investigate(More)
Recombinant microbial transglutaminase (rMTG) is usually expressed as a soluble zymogen (pro-rMTG) in heterologous expression systems but proteolytic activation of the inactive pro-rMTG is essential. Instead of screening proteases for activating pro-rMTG, we examined an alternative method by introducing a specific cleavage site of enterokinase between the(More)
Ultrasound elastography could be used as a new noninvasive technique for detecting early osteoarthritis. As the first critical step, this study theoretically predicted the excitation power and the measurement errors in detecting cartilage detect. A finite element model was used to simulate wave propagation of elastography in the cartilage. The wave was(More)
The aim of this study is to evaluate an integrated cage and plate device (the plate cage Benezech, PCB) filled with autogenous bone in anterior cervical discectomy and fusion. The fused segment height, lordosis, and fusion were assessed by postoperative radiographic examination at different intervals. Patients were evaluated using Odom's criteria and the(More)
