OBJECTIVE D-dimer is a breakdown product of fibrin mesh after factor XIII stabilization. Previously, many authors have demonstrated a relationship between D-dimer level and stroke progression or type. This study aimed to investigate the relationship between D-dimer level and stroke volume. METHODS Between January 2008 and December 2009, we analyzed the(More)
Tumor necrosis factor (TNF)-like weak inducer of apoptosis (TWEAK) is an inflammatory cytokine that modulates several biological responses by inducing chemokines and proinflammatory cytokines. We hypothesized that TWEAK could promote secretion of IL-17, an amplifier of inflammatory arthritis. To test this, we investigated the capacity of TWEAK to induce(More)
Pipes are everywhere; they are used in power plants, chemical plants, and gas, oil and water supply systems. An inpipe robot is developed, whose movement is copied from the inchworm in nature. It consists of two universal joints, and two clamping and one expansion devices, which use the compressed air as the energy source; the clamping devices are operated(More)
Interleukin-21 (IL-21) is a T cell-derived cytokine modulating T cell, B cell, and natural killer cell responses. To determine whether IL-21 contributes to pathologic processes, recombinant IL-21 receptor (R) fusion protein (rhIL-21R-Fc) was examined in mice models of autoimmune arthritis (collagen-induced arthritis). DBA/1J mice were immunized with chicken(More)
The short in vivo half-life of GLP-1 prevents it from being used clinically. This short half-life occurs because GLP-1 is rapidly degraded by dipeptidyl peptidases such as DPP-IV. To overcome this obstacle, a GLP-1/Fc was constructed and evaluated to determine if it was degraded by DPP-IV and in serum. When the degradation of GLP-1/Fc by human DPP-IV and(More)
Central corneal thickness (CCT) can be a promising source of glaucoma monitoring and diagnosis. This study evaluated changes in CCT according to experimental adjustment of intraocular pressure (IOP) in canine eyes. To adjust and measure IOP, each eye was cannulated with two 26-gauge needles under inhalant anesthesia. One needle was connected to a pressure(More)
Bone destruction is critical in the functional disability of patients with rheumatoid arthritis (RA). Osteoclasts, specialized bone-resorbing cells regulated by cytokines, such as receptor activator of NF-κB ligand (RANKL), are primarily implicated in bone destruction in RA. The aim of the study was to examine whether tumor necrosis factor-like weak inducer(More)
Pipes are everywhere; they are used in power plants, chemical plants, and gas, oil supply system. The high temperature and high pressure piping for power plants, you have to go through the gas that may remain inside the piping, the use of the electric driving device is limited. This is a robot that mimics the motion of inchworms. This robot has limited the(More)
— This paper describes the issues and challenges in the design of an interoperable mobile security card for campus-wide ubiquitous services. The card holder becomes able to take pleasure of utilizing the ubiquitous services everywhere on a campus with high security. In order to realize the services, the card has been designed to have 1) a ZigBee module for(More)
