The effect of a cell-adhesive peptide containing Arg-Gly-Asp (RGD) immobilized through poly(ethylene glycol) (PEG) on titanium (Ti) on calcification by MC3T3-E1 cells was investigated to develop a new surface modification technique using biofunctional molecules. RGD was immobilized on Ti through PEG, both terminals of which were terminated with -NH(2) and(More)
The isoelectric points (IEPs) of two zwitterions, glycine and both-terminals-terminated poly(ethylene glycol) (NH(2)-PEG-COOH), were determined from the titration curves, and the thicknesses of zwitterion layers immobilized on titanium (Ti) with immersion and electrodeposition at various pH based on IEPs were evaluated with ellipsometry to investigate the(More)
In this paper, we automatically extract statistical terms and build their co-occurrence networks from newspapers. Statistical terms are expression of the measurements of statistics to watch the movements of phenomena; birth rates, public approval rating of the Cabinet and so on. In recent years, we have a vast amount of available information because of(More)
The objective of this study was to investigate the effect of active hydroxyl groups on a titanium (Ti) surface on the bond strength between Ti and segmented polyurethane (SPU) composite through gamma-mercapto propyl trimethoxysilane (gamma-MPS). Active hydroxyl groups on Ti surface oxide were controlled by immersion in hydrogen peroxide (H2O2) with(More)
In this paper, we propose a visualization method for global dynamics. Global dynamics of various events and statistics are important to analyze complex international issues such as environmental, economic and political problems. We have been developing a system which can extract a co-occurrence network of statistical terms based on a suffix pattern(More)
The in vitro short-term platelet adhesion on various metals, as accelerated by the addition of Ca(2+), was evaluated in this study. Metals used for medical devices [an austenitic stainless steel, a cobalt (Co)-chromium (Cr)-molybdenum (Mo) alloy, a titanium (Ti)-6 aluminum (Al)-4 vanadium (V) alloy, a Ti-6Al-7 niobium (Nb) alloy, a Tinickel (Ni) alloy, and(More)

Purpose The study was aimed at investigating what kind of lip positions are selected by Japanese adult participants for an unfamiliar Mandarin rounded vowel /y/ and if their lip positions are related to and/or differentiated from those for their native vowels. Method Videotaping and post hoc tracking measurements for lip positions, namely protrusion and(More)
It is well known that the brain is one of the organs particularly affected by aging in terms of function, relative to the gastrointestinal tract and liver, which exhibit less functional decline. There is also a wide range of age-related neurological disorders such as stroke, Alzheimer's disease, and Parkinson's disease. Therefore, it is very important to(More)
Few large-scale investigations have looked at the oxyhemoglobin ratio (%O2-Hb) or the carboxyhemoglobin ratio (%CO-Hb) in fatal hypothermia and death by fire as applicable to forensic medicine. We therefore retrospectively examined right and left cardiac blood samples for both %O2-Hb and %CO-Hb in 690 forensic autopsy cases. We therefore sought to establish(More)
