The use of light for medical treatment has been studied previously. In this study, we examined the effect of light from a red light-emitting diode on osteogenic differentiation of mouse mesenchymal stem cells (D1 cells) which were cultured in the presence of osteogenic differentiation medium (ODM) for 3 days, then exposed to a red light-emitting diode (LED)(More)
PythDock is a heuristic docking program that uses Python programming language with a simple scoring function and a population based search engine. The scoring function considers electrostatic and dispersion/repulsion terms. The search engine utilizes a particle swarm optimization algorithm. A grid potential map is generated using the shape information of a(More)
In this paper, we present demand-side energy management under real-time demand-response pricing as a task scheduling problem which is NP-hard. Using minmax as the objective, we show that the schedule produced by our minMax scheduling algorithm has a number of salient advantages: significant peak-shaving, cost reduction, and risk-aversion for the consumers.(More)
STUDY DESIGN This is a retrospective study. PURPOSE We wanted to investigate the clinical relevance of the lumbar high intensity zone (HIZ) on magnetic resonance imaging (MRI) and the relationship of trauma history to internal disc disruption (IDD). OVERVIEW OF LITERATURE HIZs on lumbar spine (L-spine) MRI have been suggested as a reliable marker of IDD(More)
The purpose of this study was to evaluate the results of liner cementation into a stable acetabular shell using a metal-inlay polyethylene liner in 39 revision total hip arthroplasties. After an average of 2.8 years, 1 cemented liner dislodged from its metal shell at a postoperative 4 years. In the other 38 hips, mean Harris hip scores improved from 65(More)
Three dimensional (3D) quantitative structure-activity relationship studies of 37 B-Raf inhibitors, pyrazole-based derivatives, were performed. Based on the co-crystallized compound (PDB ID: 3D4Q), several alignment methods were utilized to derive reliable comparative molecular field analysis (CoMFA) and comparative molecular similarity indices analysis(More)
Use of SiteMap for binding site classification and its connection to QM/MM (quantum mechanics/ molecular mechanics) docking performance were investigated. Using the hydrophilic/hydrophobic character values along with balance between them which SiteMap calculates, we sorted 455 cocrystal complexes available from protein data bank into three groups and tested(More)
This study evaluated the clinical and radiographic results of 37 acetabular revisions using an acetabular roof reinforcement ring with a hook (ARRRH). The average age of the patients was 52.4 years, and the mean follow-up period was 4.5 years. The mean Harris hip score had improved from 49 points preoperatively to 87 points at the final follow-up. The bone(More)
Malunion of femoral head fractures has been rarely reported. We report on three cases of malunion of the femoral head, which were treated by partial ostectomy. All patients were involved in traffic accidents and had a posterior fracture-dislocation of the hip. The types of femoral head fractures were Pipkin type I with inferomedial fracture fragment in all(More)
BACKGROUND Theoretically, the motion of a bipolar hip prosthesis is most likely to occur at the inner joint if the frictional coefficients are equal at both surfaces. However, many studies have suggested that most motion occurs at the outer joint. MATERIAL AND METHODS We performed an analysis of motion in a cadaveric bone model and in 50 patients during(More)
