Elevated plasma levels of transforming growth factor-beta(1) (TGF-beta(1)) in patients with advanced breast cancer: association with disease progression
(European Journal of Cancer, 2003)
We examined the association between an elevated plasma TGF-beta(1) level and the disease progression of advanced breast cancer (BC) patients (n = 44). TGF-beta(1) levels were detected by an enzyme-linked immunosorbent assay ...
Synthesis of Y2SiO5 : Eu3+ nanoparticles from a hydrothermally prepared silica sol
(Journal of Alloys and Compounds, 2008)
In this paper, a novel route for the synthesis of Y2SiO5 (YSO) nanoparticles doped with Eu3+ ions. based on the use of a hydrothermally prepared silica sol as a chemical precursor and nanostructurign template, is presented. ...
Electron paramagnetic resonance studies of Hg1-xMnxTe1-ySey
(Solid State Communications, 2002)
Electron paramagnetic resonance (EPR) spectra have been measured in diluted magnetic semiconductor Hg1-xMnxTe1-ySey with y = 0.01, x = 0.01, 0.03, 0.05, 0.14 in the temperature range 20-290 K. The influence of various ...
Morphology and growth of electrodeposited silver powder particles
(Hydrometallurgy, 2007)
The effect of overpotential pulsing and periodic current reversal on the morphology of silver powders was investigated using a scanning electron microscope (SEM). It is shown that the profile of pulses or current reversal ...
Use of nonlinear frequency response for discriminating adsorption kinetics mechanisms resulting with bimodal characteristic functions
(Adsorption, 2003)
One of the characteristic examples of the inability of the classical linear frequency response (FR) method to identify the correct kinetic mechanism is adsorption of some substances (p-xylene, 2-butane, propane or n-hexane) ...
Optical and electron paramagnetic resonance spectroscopy of Cd1-xMnxS quantum dots
(Journal of Physics: Condensed Matter, 2004)
Cd1-xMnxS quantum dots (QDs) with diameter d less than or equal to 4.5 nm and with manganese concentrations from x = 0.001 to 0.15 have been prepared using aqueous solution precipitation. Absorption and fluorescence spectra ...
Gap and dark solitons in discrete photorefractive media with intensity-resonant nonlinearity
(Applied Physics. B: Lasers and Optics, 2009)
Light propagation in one-dimensional nonlinear waveguide arrays with self-defocusing intensity-resonant nonlinearity is investigated theoretically. We study thoroughly conditions for existence and stability of both gap and ...
Two new analytic approximations of the Chandrasekhars H function for isotropic scattering
(Icarus, 2008)
The Chandrasekhars H functions play a central role in theoretical descriptions of radiative transfer in planetary and stellar atmospheres. In the present work our aim is to obtain in a simple way new analytic approximations ...
Behavior of silicon carbide/cordierite composite material after cyclic thermal shock
(Ceramics International, 2009)
In the present work Mg-exchanged zeolite and silicon carbide were used as starting materials for obtaining cordierite/SiC composite ceramics with weight ratio 30:70. Samples were exposed to the water quench test from 950 ...
Theoretical assessment of phosphate amendments for stabilization of (Pb plus Zn) in polluted soil
(Waste Management, 2009)
Contamination of the environment with toxic metals, such as lead (Pb), represents a serious concern for human health. Most of the studies on Pb stabilization were performed using various phosphorus-containing amendments ...
