Virtual reality images created on the back and front of a display.

To better investigate the biological mechanism of microorganisms, we developed a novel, to the best of our knowledge, virtual reality (VR) microscope that incorporates a head-mounted display (HMD) that creates VR images with a digital microscope. This type of VR microscope can be used with any type of optical microscope. The fabricated microscope is quite different from a common bifocal device because it can create VR images on the back and front of a display.

Side edge emission from a waveguide substrate.

In this study, we fabricated embedded titanium dioxide () nanograting structures with slanted cross section on a silicon dioxide () substrate using electron beam lithography (EBL) and reactive ion etching (RIE) methods, and we analyzed their optical signals. The surface morphologies of the embedded nanograting structures were monitored by a scanning optical microscope (SEM). By focusing the transverse electric (TE) polarized beam with the wavelength =633 at the incident angle =22.

Optical Third Harmonic Generation Using Nickel Nanostructure-Covered Microcube Structures.

We investigated the optical third harmonic generation (THG) signal from nanostructure-covered microcubes on Ni. We found that the hierarchical structures greatly change the third-order optical nonlinearity of the metallic surface. While the symmetry and lightning rod (LR) effects on microstructures did not significantly influence the THG, the localized surface plasmon (LSP) effect on the nanostructures enhanced it.

Nonlinear optics on nano/micro-hierarchical structures on metals: focus on symmetric and plasmonic effects.

In this review, the authors study their creation of nano/micro-hierarchical structures on Ag and Ni substrates by femtosecond laser treatment and their investigation of their optical second-harmonic generation (SHG) signal intensities by SHG spectroscopy. The authors obtained the nanostructure-covered microgroove and microcube structures. These hierarchical surface structures were found to modify significantly the optical nonlinearity of the metal surfaces.

Pharmacokinetics, distribution, and excretion of 125I-labeled human plasma-derived-FVIIa and -FX with MC710 (FVIIa/FX mixture) in rats.

Introduction: MC710 is a mixture agent consisting of plasma-derived activated factor VII (FVIIa) and factor X (FX) at a weight ratio of 1:10 developed as a novel bypassing agent for the management of the bleeding of hemophilia patients with inhibitors. The pharmacokinetics, distribution, and excretion of (125)I-labeled-FVIIa ((125)I-FVIIa) and -FX ((125)I-FX) were studied in male rats after a single intravenous administration of (125)I-FVIIa or (125)I-FX combined with MC710.

Methods: (125)I-FVIIa or (125)I-FX was administered intravenously with MC710 to male rats in a single dosage (FVIIa 0.

Stacks of nucleic acids as molecular wires: direct measurement of the intermolecular band dispersion in multilayer guanine assemblies.

The intermolecular band dispersion related to the highest occupied molecular orbital in highly ordered, hydrated multilayer films of the DNA base guanine has been measured using photon-energy-dependent ultraviolet photoelectron spectroscopy. A bandwidth of 331 ± 8 meV at room temperature and a small effective mass of about 1.11 times that of a free charge suggest a high intrinsic hole mobility along quasi-one-dimensional stacks formed perpendicular to layered, hydrogen-bound networks.

Combining FVIIa and FX into a mixture which imparts a unique thrombin generation potential to hemophilic plasma: an in vitro assessment of FVIIa/FX mixture as an alternative bypassing agent.

Introduction: We previously reported that a combination of factors VIIa (FVIIa) and X (FX) might represent an effective and attractive alternative to recombinant factor VIIa (rFVIIa) and plasma-derived activated prothrombin complex concentrate (APCC) for controlling bleeding in hemophiliacs with inhibitors. The present study describes the standardization and preparation of a virus-inactivated and nano-filtrated plasma-derived FVIIa/FX concentrate. We hypothesized that the hemostatic capacity was equivalent to or better than current bypassing agents as evaluated by measurements of waveform APTT clotting and thrombin generation.

Von Willebrand factor accelerates platelet adhesion and thrombus formation on a collagen surface in platelet-reduced blood under flow conditions.

Plasma von Willebrand factor (VWF) has been identified as an indispensable factor for platelet adhesion and thrombus formation on a collagen surface under flow conditions. VWF binds to collagen and then tethers platelets to the collagen surface through interaction with platelet glycoprotein Ib and also contributes to the thrombus formation on the collagen surface. In the present study, we demonstrated that the addition of VWF/factor VIII complex or purified VWF (> 2 ristocetin cofactor activity units/mL) increased platelet adhesion to the collagen surface in platelet-reduced blood ( approximately 5 x 10(4) platelets/microL) to the normal level.
