In cell transplantation therapy for the treatment of neurodegenerative disorders, encapsulation of implanted cells in a semipermeable membrane is a promising approach to protect the implanted cells from host immune rejection and inhibit the invasion of tumor into surrounding tissue if the implanted cells form a tumor after transplantation. However, implanted neurons isolated by capsules could n...

Understanding of T helper 17 lineage (TH17) polarization has been significantly promoted by cell culture experiments that reduce the complexity of the in vivo environment. We here investigated TH17 amplification by coating of cytokine preparations. Cytokine preparations coated to the surface compared to the same amount given in solution significantly enhanced TH17 polarization assessed by flow ...

Scanning-beam interference lithography (SBIL) is a novel concept for nanometeraccurate grating fabrication. It can produce gratings with nanometer phase accuracy over large area by scanning a photoresist-coated substrate under phase-locked image grating. For the successful implementation of the SBIL, it is crucial to measure the spatial period, phase, and distortion of the image grating accurat...

We have investigated the process of somatic-type cytokinesis in Arabidopsis (Arabidopsis thaliana) meristem cells with a three-dimensional resolution of approximately 7 nm by electron tomography of high-pressure frozen/freeze-substituted samples. Our data demonstrate that this process can be divided into four phases: phragmoplast initials, solid phragmoplast, transitional phragmoplast, and ring...

A unique, sensitive, and highly specific immunoassay system for antibodies using gold nanoparticles has been developed. The assay is based on the aggregation of gold nanoparticles that are coated with protein antigens in the presence of their corresponding antibodies. The aggregation of the gold nanoparticles results in an absorption change at 620 nm that is monitored using an absorption plate ...

Cutting processes of carbon fibre reinforced polymer (CFRP) material generate significant energy in the form heat which can be detrimental to final surface and sub-surface quality. By artificially changing temperature workpiece simulate cutting temperatures, thermal effects on friction metrics understood. Feed rate CFRP pre-heating for macro nanoscale open loop pin plate testing has been comple...

Poly(ethylene oxide) brushes have been covalently bound to glass surfaces and their presence was demonstrated by an increase in water contact angles from fully wettable on glass to advancing contact angles of 54 degrees, with a hysteresis of 32 degrees. In addition, electrophoretic mobilities of glass and brush-coated glass were determined using streaming potential measurements. The dependence ...

The effects of extracellular matrix (ECM) proteins and cationic polymers on the adhesion and proliferation of rat islet cells, RIN-5F cells, were investigated. ECM proteins of laminin, fibronectin, vitronectin, type I collagen, type II collagen, and type IV collagen, and cationic polyelectrolytes of poly(L-lysine) and poly(allylamine) were coated on the wells of polystyrene cell culture plates....

A biofuel cell (BFC) cathode has been developed based on direct electron transfer (DET) of hemoglobin (Hb) molecules with an indium-tin-oxide (ITO) electrode and their electrocatalysis for reduction of hydrogen peroxide (H2O2). In this study, the ITO-coated glass plates or porous glasses were prepared by using a chemical vapor deposition (CVD) method and examined the electrochemical characteris...
