OBJECTIVE To study the feasibility of engineering cartilage tissue in a tube lined with epithelium and implanting allogenic chondrocytes in a novel scaffold that is made of chitosan nonwoven cloth coated with poly(DL-lactide-co-glycolide). DESIGN Laboratory research. SUBJECTS Allogenic chondrocytes were obtained from the auricles of 1-month-old New(More)
BACKGROUND Hepatocellular carcinoma (HCC) is the sixth most common cancer worldwide and the most common form of liver cancer. However, while it is associated frequently with hepatitis C virus (HCV) there is only an elementary understanding of its molecular pathogenesis. METHODS To gain insight into the molecular mechanisms of HCV-induced(More)
OBJECTIVE To study the repair of the rabbit ear cartilage defects with transforming growth factor-beta1 (TGF-beta1) and allogenic chondrocyte/poly-DL-lactide (PDLLA) higher porosity polymer. METHODS A total of 18 rabbits were divided into the TGF-beta1 and chondrocytes/PDLLA graft group, the chondrocytes/PDLLA graft group, and the blank control group.(More)
Lung cancer seriously threatens human health, so it is important to investigate gene expression changes in affected individuals in comparison with healthy people. Here we compared the gene expression profiles between smokers with and without lung cancer. We found that the majority of the expressed genes (threshold was set as 0.1 RPKM) were the same in the(More)
OBJECTIVE To investigate the possible effects of intranasal corticosteroids on the focal bacterial colonization and mucosal histomorphological changes in experimental acute bacterial maxillary sinusitis in rabbits. METHODS Acute bacterial maxillary sinusitis was induced in 48 rabbits. They were divided into 4 groups: antibiotic group (group A), antibiotic(More)
The study aims to investigate the feasibility of repairing cartilaginous defects with chondrocytes induced from allogenic bone marrow mesenchymal stem cells (BMMSC) in rabbits’ ear. BMMSCs were isolated and purified from New Zealand rabbits, in vitro amplified, and cultured in chondrocyte induction medium in order to acquire chondrocytes. After 3 weeks of(More)
In this paper, we study a software-focused products and service supply chain based on the practice of two leading electronic manufacturing services providers in the world and their major corporate clients. We discuss the common and unique issues that a software-focused supply chain has compared with a traditional supply chain. We also indicate the research(More)
The frontal sinus surgery is difficult to perform but the ethmoid bulla is a relative, constant landmark in the middle turbinate that can improve the surgery. The purpose of this study was to evaluate the validity, security, and predominance of approaches to the frontal sinus via the route anterior to the ethmoid bulla. The data from 370 endoscopic frontal(More)
OBJECTIVES To apply the technique of injection of a combination of autologous fascia lata and fat into the vocal fold via the cricothyroid gap for unilateral vocal fold paralysis and to evaluate the therapeutic effect in 12 patients who underwent the procedure. DESIGN Retrospective analysis of 12 patients. SETTING Academic research. PATIENTS A mixture(More)
Traditional frontal sinus surgery is associated with a significant trauma. Herein, we have discussed the feasibility, technique, and efficacy of a minimally invasive anterior-to-ethmoidal bulla surgical approach performed under nasal endoscopy to treat isolated frontal sinusitis. Fifteen patients with isolated frontal sinusitis underwent the(More)
