L-FABP mRNA increased sharply in response to PHx but the increase was short lived, while L-FABP level increased at a later stage. Both L-FABP content and fatty acid uptake increased significantly during liver regeneration induced by PHx in rats. It is likely that L-FABP is one of the factors responsible for hepatic regeneration.
Manganite perovskite La1-xCaxMnO3(x=0.33, 0.5 and 0.9) have been prepared by chemical co-precipitation method. Ammonium carbonate was used to coprecipitate lanthanum, calcium and manganese ions as carbonates under basic condition. This precursor on calcining at 900°C yields La-Ca-Mn-O perovskite phase. Follow by sintering at 1200°C after the powders were pressed into pellets gave La1-xCaxMnO3(LCMO) polycrystalline ceramics. The crystal phases of the resulting powders and ceramics were examined by X-ray diffraction (XRD) technique. The morphology of the powders was observed by scanning electron microscopy (SEM) and electrical transport properties of ceramics were measured by conventional four-point probe technique.
La1-xCaxMnO3 (x=0.0-1.0) epitaxial thin films were deposited on both tilted and untilted LaAlO3 (0 0 1) single crystalline substrates using PLD (pulsed laser deposition) technique, in which the employed qualified polycrystalline La1-xCaxMnO3 targets were synthesized by sol-gel method. The structural properties and the ultraviolet LITV (laser induced thermoelectric voltage) effect of the as-grown films on the tilted substrates were studied. The results demonstrate that the intensities of the LITV signals depend non-monotonously on Ca content, that is, the peak values of the LITV signals firstly increase and then decrease with Ca content increasing. The maximal peak value of LITV was found in the film with Ca=0.33.
La2/3Ca1/3MnO3:Ag0.05(LCMO:Ag0.05) thin films were prepared on vicinal cut LaAlO3(LAO) substrates with various film thicknesses by pulsed laser deposition technique (PLD). XRD results show that all the samples are shown along the (00l) orientation in orthorhombic structure with Pbnm space group. While the film thickness is around 450nm, the optimum LIV effects of the epilayer thin film have been obtained. The LIV effects enhancement of the LCMO:Ag0.05 thin films due to the photon scattering effects have been restrained and anisotropic seebeck coefficient improved.
LaNiO3 single layer, LaNiO3/LaAlO3 superlattice on vicinal-cut single crystalline LaAlO3 (100) and LSAT (100) substrates were prepared by pulsed laser deposition technique. Single-phased LaNiO3 polycrystal target, which is synthesized by sol-gel method, is employed in the thin film deposition process. The structure and physical properties of both the targets and thin films are analyzed. X-ray diffraction results show LaNiO3 single layer is of c-orientation and textural growth, therefore LaNiO3/LaAlO3 forms not superlattice but multilayer. The ultra-violet LITV (laser induced thermoelectric voltage) effects of the LaNiO3/LaAlO3 mutilayer and LaNiO3 single layer were investigated. A comparison study of the influence of LaNiO3 targets prepared by different sol-gel method on the physical property, and LITV effect of thin films was performed as well.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
