Myofibroblasts that express alpha-smooth muscle actin (alpha-SMA) are detected in many chronic inflammatory diseases. Transforming growth factor-beta (TGF-beta) is a potent inducer of myofibroblast accumulation in tissues. In this study, scattered myofibroblasts and TGF-beta were quantified and localized in nasal polyps (NPs) and normal nasal mucosa (NM).(More)
OBJECTIVE To determine the expression and the potential role of transforming growth factor beta (TGF-beta) in nasal polyposis. DESIGN Comparison of TGF-beta expression between normal and inflammatory nasal mucosa and polyps; in inflammatory nasal polyps, characterization of the TGF-beta isoforms expression and their potential location in macrophages and(More)
BACKGROUND Local anesthetic containing epinephrine is commonly used in many operations for the main purpose of hemostasis. A randomized, controlled, prospective clinical trial was designed to find out hemodynamic changes after local infiltration of different concentrations and/or different dosages of epinephrine during functional endoscopic sinus surgery(More)
OBJECTIVES Local anesthetics containing adrenaline, which often cause cardiovascular side effects, are routinely used in functional endoscopic sinus surgery (FESS) for the main purpose of hemostasis. The controversies concerning hemodynamic effects of adrenaline in local infiltration are widely discussed, but there is no definite conclusion. A prospective,(More)
The modifications of epithelial differentiation and proliferation observed in nasal polyps (NP) could be related to local secretion of growth factors, among which platelet-derived growth factor (PDGF) could play a key role. We therefore prospectively studied, by immunohistochemistry, proliferating cell nuclear antigen (PCNA, an S-phase cell marker), PDGF,(More)
Now a number of advanced control systems take advantage of networks such as Ethernet ,Fieldbus and Internet as their communication channel. Transmission time delay of these networks may lead unstable problems to system. In this paper, the predication of network delay using neural network is presented first. Then the analysis of the control oriented Quality(More)
STUDY DESIGN This case report illustrates three patients with extraforaminal disc herniation in the lumbar spine. OBJECTIVES Treatment consisted of discectomy through an intertransverse approach. SUMMARY OF BACKGROUND DATA The surgical treatment of lumbar disc herniation has been well studied and reported in the literature. Laminectomy, foraminotomy,(More)
Objective: To investigate the characteristics of lower airway abnormalities in allergic rhinitis(AR) patients without asthma. Methods: Between June 2008 and December 2012, 377 consecutive AR patients and 264 healthy subjects were recruited. All subjects underwent meticulous history taking, nasal examination, allergen skin prick test, blood routine test,(More)
To guarantee the success of Automatic Switched Optical Network (ASON) management, some important factors, such as state of the network element and environment contexts must be taken into account. This paper explores a mobile agent (MA) approach to support ASON management. The mobile agents are created dynamically according to the demand and dispatched into(More)
Synchronized wide area communication has become a mature technology, which makes the real-time interaction between the substations and the wide area protection and control system possible. However, the present protection and control system to handle this real-time data has been recognized to be deficient. This paper begins by reviewing the development(More)
