Journal ArticleDOI
In vitro blood flow in a rectangular PDMS microchannel: experimental observations using a confocal micro-PIV system.
Rui Lima,Shigeo Wada,Shuji Tanaka,Motohiro Takeda,Takuji Ishikawa,Ken-ichi Tsubota,Yohsuke Imai,Takami Yamaguchi +7 more
TL;DR: The present study clearly shows that confocal micro-PIV can be effectively integrated with a PDMS microchannel and used to obtain blood velocity profiles along the full depth of the microchannel because of its unique 3-D optical sectioning ability.
Journal ArticleDOI
In vivo imaging of spontaneous ultraweak photon emission from a rat’s brain correlated with cerebral energy metabolism and oxidative stress
Masaki Kobayashi,Motohiro Takeda,Tomoo Sato,Yoshihiko Yamazaki,Kenya Kaneko,Ken-Ichi Ito,Hiroshi Kato,Humio Inaba +7 more
TL;DR: In conclusion, imaging of ultraweak photon emission from a brain constitutes a novel method, with the potential to extract pathophysiological information associated with neural metabolism and oxidative dysfunction of the neural cells, and this intensity is associated with the cerebral blood flow and hyperoxia.
Journal ArticleDOI
Radial dispersion of red blood cells in blood flowing through glass capillaries: the role of hematocrit and geometry
TL;DR: The information provided by this study not only complements previous investigations on microhemorheology of both dilute and concentrated suspensions of RBCs, but also shows the influence of both Hct and geometry on the radial dispersion of R BCs.
Journal ArticleDOI
Size-selective growth and stabilization of small CdSe nanoparticles in aqueous solution.
Yeon Su Park,Yeon Su Park,Andriy Dmytruk,Igor Dmitruk,Atsuo Kasuya,Motohiro Takeda,Noriaki Ohuchi,Yukihiro Okamoto,Noritada Kaji,Manabu Tokeshi,Yoshinobu Baba +10 more
TL;DR: General trends for the possibility of selective growth of stable semiconductor NPs with particular sizes in aqueous solution are shown and it is seen that capping molecules having relatively compact outermost spatial geometry led to NPsWith excellent long-term stability, whereas those having relatively bulky outer most spatial geometry produced NPswith at most only moderate long- term stability.
Journal ArticleDOI
In vitro confocal micro-PIV measurements of blood flow in a square microchannel: The effect of the haematocrit on instantaneous velocity profiles
TL;DR: The confocal micro-PIV measurements demonstrate that the root mean square (RMS) values increase with the haematocrit implying that it is important to consider the information provided by the instantaneous velocity fields, even at low Re.
