Clinical studies have shown a correlation of HER-2/neu amplification/over-expression and favorable response to neoadjuvant chemotherapy and anti-HER-2/neu antibody treatment. However, contradictory findings also have been reported. Some tumors may develop resistance to neoadjuvant chemotherapy after an initial period of sensitivity. Our study attempts to(More)
In this study, we demonstrate the application of immunomagnetic labeling and magnetic resonance imaging (MRI) for the noninvasive visualization of changes in bacterial density distributions as a function of time in a water-saturated porous medium. Magnetite particles (50-60 nm diameter) were attached via a monoclonal antibody to the surface' of Escherichia(More)
The effects and mechanisms of locally applied d-amphetamine (AMPH) into the ventral tegmental area (VTA) on extracellular dopamine (DA) concentrations in both the nucleus accumbens (N ACC) and the medial prefrontal cortex (mPFC) were investigated. A solution containing either, 0, 100, 500 or 1000 microM AMPH was infused, using a 1-ml Hamilton syringe, into(More)
This work demonstrates a simple route for synthesizing multi-functional fluorescent nanodiamond-gold/silver nanoparticles. The fluorescent nanodiamond is formed by the surface passivation of poly(ethylene glycol) bis(3-aminopropyl) terminated. Urchin-like gold/silver nanoparticles can be obtained via one-pot synthesis, and combined with each other via(More)
Nitride LED (e.g., GaN) has become the mainstream of blue light source. The blue light can be converted to white light by exciting a phosphor (e.g., Nichia's YAG or Osram's TAG) with the complementary yellow emission. However, GaN is typically deposited on sapphire (Al2O3) substrates formed by crystal pulling or hexagonal (e.g., 4 H or 6 H) SiC wafers(More)
The order of the stress singularity of a magnetoelectroelastic bonded antiplane wedge is analyzed by complex potential function and eigenfunction expansion method. Contrary to the familiar problem of elastic anisotropic bonded wedges which always produce real values for the order of singularity, the results of the magnetoelectroelastic bonded wedges may be(More)
Mono to few-layer graphene were prepared on pre-annealed polycrystalline nickel substrates by chemical vapor deposition at a relatively low temperature of 800 degrees C using fast cooling rate. It was observed that the reduced solubility of Carbon in Ni at low temperature and an optimum gas mixing ratio (CH4:H2 = 60/80 (sccm)) can be used to synthesize(More)
