Osteoarthritis (OA) is the most common joint disorder that has had an increasing prevalence due to aging of population. Recent studies have concluded OA progression related oxidative stress and reactive oxygen species (ROS). ROS are produced at low levels in articular chondrocytes, mainly by nicotinamide adenine dinucleotide phosphate (NADPH) oxidase, production been found be elevated patients with OA. The cartilage OA-affected rat exhibits a significant induction p47phox, cytosolic subunit...
In the field of book search, research on a web service-based user-customized recommendation system is being conducted to respond increasingly diverse user requirements. The collaborative filtering algorithm, which mainly used for recommendation, has problem in that it difficult reflect user’s recent interest without considering changes preference over time, and satisfaction decreases because repeatedly recommends only similar items. this paper, we propose method using category similarity...
Osteoarthritis (OA) is the most common type of joint disease associated with cartilage breakdown. However, role played by mitochondrial dysfunction in OA remains inadequately understood. Therefore, we investigated p66shc during oxidative damage and effects downregulation on progression.Monosodium iodoacetate (MIA), which commonly used to generate animal models, inhibits glycolysis biosynthetic processes chondrocytes, eventually causing cell death. To observe MIA poly(lactic-co-glycolic acid)...
Background: The goal of the present study was to define dimensions normal rotator interval with magnetic resonance arthrography and compare these those in shoulders known chronic anterior instability order determine if abnormalities might be better understood estimated preoperatively. Methods: We retrospectively reviewed a consecutive series 202 that had undergone between 2004 2005. Of these, 120 were included study. These divided into two groups according diagnosis. Group I comprised fifty...
Because inflammation in osteoarthritis (OA) is related to the Toll-like receptor 4 (TLR4) signaling cascades, TLR4 a reasonable target for developing therapeutics OA. Thus, we investigated whether TAP2, peptide antagonist of TLR4, reduces monoiodoacetate (MIA)-induced arthritic pain and cartilage degradation rats. expression human OA chondrocytes synoviocytes knee joint tissue MIA-induced arthritis were evaluated. model using Sprague-Dawley rats (6 week-old-male) treated with antagonist,...
Background and Objectives: This study investigated associated meniscus ligament injuries in tibial plateau fractures using magnetic resonance imaging (MRI) assessed soft tissue relation to the Schatzker classification Tscherne classification. Materials Methods: The data of 185 patients who sustained from January 2010 April 2021 were retrospectively reviewed. Fractures classified according system. Soft-tissue Menisci ligaments evaluated preoperative MRI. Nerve injuries, compartment syndrome...

Psychogenic dysphagia is a deglutition disorder characterized by fear of swallowing, with no structural or functional causes. This report presents the case young male patient who had severe malnutrition due to psychogenic and was provided visual biofeedback using fiberoptic endoscopic evaluation swallowing (FEES). A healthy 25-year-old man presented our clinic complaint throat discomfort when that started 6 months prior. As symptoms worsened, he became fearful food spreading his lungs after...
The theme, background, and signal music usage history information consists of general such as information, platform sensitive rights management permission range, contract information. If among these is disclosed, disputes trade secrets infringement personal protection between companies or individuals may arise. We propose a selective encryption/decryption method to secure the confidentiality, integrity, reliability non-repudiation used in blockchain environment. In proposed method,...
Theme, background and signal music is the inserted into broadcasting contents of a broadcaster, recognized as created content like normal music. Since there are lyricists composers who have rights music, copyright fee distributed. However, often occur problems with inaccurate monitoring results for theme, usage due to omission details non-transparent settlement method. In this paper, we propose method generating information based on blockchain, which source recorded by tool feature-based...
While it is suggested that platelet hyperreactivity plays a role in the arterial thrombi, its link with venous thromboembolism (VTE) not well defined. Aggregometry using low concentrations of agonists proposed as reliable method to detect hyperreactivity. The aim this study was examine whether affects development VTE after total knee arthroplasty (TKA).Total 150 elderly patients without history were enrolled. Mechanical prophylaxis used for TKA. We performed aggregation Chrono-log...
One of key issues organic solar cells (OSCs) is to protect them from oxygen and moisture. The most commonly used method utilizes UV-cured epoxy along with a desiccant inside the glass-capped OSC devices. Though conventional glass encapsulation allows high gas diffusion barrier, yet device opaque, which makes it difficult fabricate transparent device. For small molecule based photovoltaic devices, we come up an advanced where liquid getter filled. A highly first coated on flat UV-cured. then...
Si1-xGex layers were deposited using Si2H6/GeH4 and Si3H8/GeH4 by ultrahigh vacuum chemical vapor deposition, the effect of Si precursor type on surface roughnening is investigated. The root mean square (RMS) roughness that either Si2H6 or Si3H8 was increased gradually with increasing film thickness, resulting in an increase amplitude wavy below critical thickness for formation threading dislocations. residual strain SiGe decreased significantly through defect abrupt RMS larger than...
This paper proposes a group-based collusion-secure code design technique for protecting copyrights on digital contents. Designing codes were difficult and there problems in creating these large numbers, as should enable detecting collusion attacks when occurring content with inserted forensic marks. In addition, was problem applying to actual services that unique user-specific could not be issued. group anti-collusion (ACCs) made by introducing the concept of groups existing balanced...
<title>Abstract</title> The capacitance behavior of the ultra-thin ferroelectric/dielectric (FE/DE) stacked devices in nanoscale cylindrical structure deviated from negative (NC) state to unpredicted other states. This work confirmed that (2.0–3.0 nm) FE Hf<sub>0.33</sub>Zr<sub>0.67</sub>O<sub>2</sub> layer could have a positive capacitance, infinite or NC by controlling thickness DE Al<sub>2</sub>O<sub>3</sub> (1.0–3.0 nm). Detailed analytical model and numerical simulation based on...
