PURPOSE In the present study, the clinical outcomes and second-look arthroscopic findings of intra-articular injection of stem cells with arthroscopic lavage for treatment of elderly patients with knee osteoarthritis (OA) were evaluated. METHODS Stem cell injections combined with arthroscopic lavage were administered to 30 elderly patients (≥65 years)(More)
PURPOSE This study compared the clinical results and second-look arthroscopic findings of patients undergoing open-wedge high tibial osteotomy (HTO) for varus deformity, with or without mesenchymal stem cell (MSC) therapy. METHODS This prospective, comparative observational study was designed to evaluate the effectiveness of MSC therapy. The patients were(More)
Detection and quantitation of nucleic acids have gained much importance in the last couple of decades, especially in the post-human genome project era. Such processes are tedious, time consuming and require expensive reagents and equipment. Therefore, in the present study, we demonstrated a simple process for the separation and analysis of small DNA(More)
Numerous studies have identified beta-amyloid(1-42) protein (Abeta42) in the cerebrospinal fluid as a potential biomarker of Alzheimer's disease. It is of particular interest to establish the diagnosis before reaching the stage of clinical severity. The current methods for studying amyloid detection, however, is often time-consuming, expensive, and labor(More)
OBJECTIVES This study describes the outbreaks of H5N8 highly pathogenic avian influenza (HPAI) in Korea during the first wave, from January 16, 2014 through July 25, 2014. Its purpose is to provide a better understanding of the epidemiology of H5N8 HPAI. METHODS Information on the outbreak farms and HPAI positive wild birds was provided by the Animal and(More)
A fully integrated microchip for performing cell lysis, polymerase chain reaction (PCR) and quantitative analysis of DNA amplicons in a single step is described herein. The chip was built on glass substrate using an indium-tin-oxide (ITO) microheater and PDMS engraved microchannels, which integrated an electrochemical cell lysis zone, a continuous flow PCR(More)
This paper presents new material data for single-and multi-layer CMOS compatible poly-SiGe films, including mechanical quality factor (Q), Young's modulus, and strain gradient. Using audio frequency folded-flexure comb-drive resonators, the mechanical quality factor of poly-SiGe was determined at 2µTorr pressure. As-deposited poly-SiGe has Q = 20,000 –(More)
We have developed microsystems with a capillary electrophoresis and an electrochemical detector. The microfabricated CE-ECD systems are adequate for a disposable type and the characteristics are optimized for application in electrochemical detection. The system was realized by means of a polydimethylsiloxane (PDMS)-glass chip and an indium tin oxide(More)
PURPOSE To compare the clinical and radiologic efficacy of adipose-derived stem cells (ADSCs) with fibrin glue and microfracture (MFX) versus MFX alone in patients with symptomatic knee cartilage defects. METHODS Patients who were aged 18 to 50 years and had a single International Cartilage Repair Society grade III/IV symptomatic cartilage defect (≥3(More)
The occurrence of Bovine Spongiform Encephalopathy (BSE, so called mad cow diseases) that was first identified in England in 1986 was considered as being limited to only European countries, including England. However, the outbreak in Asia as well as North America since 2001 has amplified the fear that there isn't any nation in the world that is a safe area.(More)
