This study examined the antibacterial activity of prepolymerized resin filler, in which the bactericide quaternary ammonium was immobilized. The experimental filler was prepared by grinding prepolymerized resin blocks of methacrylate monomers, silica particles, and the antibacterial monomer methacryloyloxydodecylpyridinium bromide (MDPB). The number of(More)
This study examined the hypothesis that experimental primer containing the antibacterial monomer 12-methacryloyloxydodecylpyridinium bromide (MDPB), which was previously reported to show bactericidal effects in vitro, inhibits bacteria in cavities under in vivo conditions. The number of bacteria resulting from applying primer solution to cavities in dog(More)
Monte-Carlo Tree Search (MCTS) is remarkably successful in two-player games, but parallelizing MCTS has been notoriously difficult to scale well, especially in distributed environments. For a distributed parallel search, transposition-table driven scheduling (TDS) is known to be efficient in several domains. We present a massively parallel MCTS algorithm,(More)
PURPOSE To determine and compare the intrinsic antibacterial activity of commercially available simplified adhesive systems. MATERIALS AND METHODS The antibacterial activity of five self-etching/priming one-step adhesives and three priming/bonding adhesives against Streptococcus mutans, Lactobacillus casei, and Actinomyces viscosus was assessed by the(More)
OBJECTIVE To evaluate the efficacy of low dose tamsulosin for facilitating spontaneous passage of ureteral stones in Japanese male patients. METHODS A total of 71 patients with symptomatic ureteral stones, 10 mm or smaller in size, were randomly allocated into groups 1 and 2. Group 1 received tamsulosin (0.2 mg/day) for a maximum of 4 weeks and group 2(More)
The lethal ventricular arrhythmia Torsade de pointes (TdP) is the most common reason for the withdrawal or restricted use of many cardiovascular and non-cardiovascular drugs. The lack of an in vitro model to detect pro-arrhythmic effects on human heart cells hinders the development of new drugs. We hypothesized that recently established human induced(More)
OsPIP1;1 is one of the most abundant aquaporins in rice leaves and roots and is highly responsible to environmental stresses. However, its biochemical and physiological functions are still largely unknown. The oocyte assay data showed OsPIP1;1 had lower water channel activity in contrast to OsPIP2;1. EGFP and immunoelectron microscopy studies revealed(More)
To investigate the roles that the community effect and entrainment function of cultured cardiomyocyte play in decreasing beating fluctuation and reestablishing synchronized beating, we developed a single-cell-based two-dimensional network culture assay to measure and compare the dynamics of beating rhythm synchronization of individual cells before and after(More)
We propose a multifocus scanning technique in second-harmonic-generation (SHG) microscopy in which the SHG detection efficiency and the image acquisition rate are improved by several tens of times compared with typical single-focus scanning techniques. Because of a microlens array scanner, the laser beam of a mode-locked Ti:sapphire laser is split into ~100(More)
