The new three-dimensional structure that the graphene connected with SWCNTs (G-CNTs, Graphene Single-Walled Carbon Nanotubes) can solve graphene and CNTs' problems. A comprehensive study of the mechanical and electrical performance of the junctions was performed by first-principles theory. There were eight types of junctions that were constituted by armchair and zigzag graphene and (3,3), (4,0)...

A numerical study is presented to investigate the electronic transport properties through a synthetic DNA molecule based on a quasiperiodic arrangement of its constituent nucleotides. Using a generalized Green's function technique, the electronic conduction through the poly(GACT)-poly(CTGA) DNA molecule in a metal/DNA/metal model structure has been studied. Making use of a renormalization schem...

Cell inflammation disrupts intestinal barrier functions and may cause disorders related to a leaky gut, possibly leading diabetes. The objective of this study was determine if carao (Cassia grandis) incorporated into yogurt enhances in vitro function. To achieve goal, Caco-2 cells were used as model permeability. treated with cytokines (interleukin-1β, tumor necrosis factor-α, interferon-γ, lip...

An 82-kD protein has been purified from the undercoat of the adherens junction isolated from the rat liver. The purification scheme includes low salt extraction followed by DEAE-cellulose ion exchange, DNase I-actin affinity, and carboxyl methyl-cellulose ion exchange chromatographies. The purified 82-kD protein was essentially free of contaminants as judged by SDS-PAGE combined with silver sta...

We have previously reported that EFA6, exchange factor for Arf6, is implicated upon E-cadherin engagement in the process of epithelial cell polarization. We had found that EFA6 acts through stabilization of the apical actin ring onto which the tight junction is anchored. Mutagenesis experiments showed that both the catalytic domain of EFA6 and its C-terminal domain were required for full EFA6 f...

A recently developed technique for ultra shallow pn junction formation has been applied for the fabrication of ringgate n-channel junction field effect devices (JFET) devices. Several different geometries, gate formation parameters and channel doping profiles have been realized and characterized with respect to I-V and C-V characteristics both on wafer and after packaging. Low-frequency noise m...
