ABSTRACT: To compare the effective rates among one week, two week and four week treatment sessions of ozone therapy for lumbar disc herniation to provide a foundation for clinical decision-making. One hundred and eighty-seven lumbar disc herniation patients were divided into three groups, 103 cases for one week, 61 cases for two week and 23 cases for four week treatment sessions. The clinical curative effective rates in the three groups were 82.52%, 85.24% and 95.65% respectively. The effective rate among the three groups showed no significant difference at statistical analysis. Considering the cost-effectiveness of ozone therapy, increasing the treatment course does not enhance the curative effect.

ABSTRACT: A series of polypyrrole-LiFePO4 (PPy-LiFePO4) composites were synthesised by polymerising pyrrole monomers on the surface of LiFePO4 particles. AC impedance measurements show that the coating of polypyrrole significantly decreases the charge-transfer resistance of LiFePO4 electrodes. The electrochemical reactivity of polypyrrole and PPy-LiFePO4 composites for lithium insertion and extraction was examined by charge/discharge testing. The PPy-LiFePO4 composite electrodes demonstrated an increased reversible capacity and better cyclability, compared to the bare LiFePO4 electrode.

ABSTRACT: Peptides containing the extracellular matrix peptide cell attachment sequence RGD possess potent, endothelium-dependent vasorelaxant properties. In the present study, the ability of RGD-containing peptides to cause vasorelaxation in the presence and absence of a functional endothelium was examined in rat aortic rings along with the ability of RGD-containing peptides to increase cGMP production in these vessels. The active RGD-containing peptide GRGDNP induced rapid relaxation in endothelium-intact, norepinephrine contracted rat aortic rings. When the endothelium was removed, RGD-containing peptides produced a slow relaxation of contracted rings which took approx. 40 min to reach maximum relaxation. Control RGD peptides were without effect either in the presence or absence of a functional endothelium. While acetylcholine and sodium nitroprusside stimulated cGMP production in endothelium-intact and denuded aortic segments, neither the control RGD peptide nor the active GRGDNP increased cGMP in these vessels when compared to controls upon either short (30 s) or long (45 min) incubation times. These data indicate that relaxations of rat aortic rings in response to RGD-containing peptides occur both in the presence and absence of an intact endothelium and that cGMP is likely not the sole mediator of these responses.

ABSTRACT: Studies have been conducted on the equilibrium distribution of Au(III) between hydrochloric acid media and chlorinated organic solvents with nonionic surfactants, polyoxyethylene nonyl phenyl ethers (PONPEs). The equilibrium constants were determined on the basis of the stoichiometric relation as: AuCl4− + H+ + ⇌ The extraction efficiencies increased with an increase in ethylene oxide number of the surfactant, whereas for the diluent the order was chloroform < dichloromethane < dichloroethane.The selective extraction of Au(III) to some heavy metals (Pd(II), Pt(IV), Zn(H), Cu(II) and Fe(III)) could be attained satisfactorily, and the back extraction of Au(III) from the loaded solvent was realized by using water as the stripping solution. Successful application of the present extraction system to a gold leach liquor from a printed substrate was demonstrated.

ABSTRACT: Enriched Xenon Observatory (EXO)-200 uses 468 large area avalanche photodiodes (LAAPDs) for detection of scintillation light in an ultra-low-background liquid xenon (LXe) detector. We describe initial measurements of dark noise, gain and response to xenon scintillation light of LAAPDs at temperatures from room temperature to 169 K—the temperature of liquid xenon. We also describe the individual characterization of more than 800 LAAPDs for selective installation in the EXO-200 detector.
