: Electroconvulsive therapy (ECT) can be effective in patients with depression resistant to pharmacologic medication. We report that serum levels of glial cell-line derived neurotrophic factor (GDNF) were increased following ECT of patients with drug-resistant depression. When patients were sub-classified into ECT responders and non-responders, serum GDNF levels were significantly increased (58%) in responsive patients following ECE No significant increase was seen in non-responders. These results suggest that successful ECT may be associated with elevated serum GDNF levels. (C) 2009 Elsevier Ireland Ltd. All rights reserved.

: Modern rice (Oryza sativa L.) cultivars, especially the newly bred 'super' rice, have numerous spikelets on a panicle with a large yield capacity. However, these cultivars often fail to achieve their high yield potential due to poor grain-filling of later-flowering inferior spikelets (in contrast to the earlier-flowering superior spikelets). Conventional thinking to explain the poor grain-filling is the consequence of carbon limitation. Recent studies, however, have shown that carbohydrate supply should not be the major problem because they have adequate sucrose at their initial grain-filling stage. The low activities of key enzymes in carbon metabolism may contribute to the poor grain-filling. Proper field practices, such as moderate soil drying during mid- and late grain-filling stages, could solve some problems in poor grain-filling. Further studies are needed by molecular approaches to investigate the signal transport, the hormonal action, the gene expressions, and the biochemical processes in inferior spikelets.

: New approach to spin dynamics simulation in magnetic system is presented. In the approach, we substitute new algorithm for Landau-Lifshitz-Gilbert dynamics. which enable us to achieve the final stable state of magnetic system much faster than traditional spin dynamics simulation. A square-shaped sample with 32 x 32 x 4 size under different conditions is calculated. Our results show the new approach can largely reduce the computational time. (C) 2009 Elsevier B.V.

: In this paper, we study a class of nonlinear value boundary problems for second order differential inclusions. By using the methods of upper-lower solutions, truncations and penalization, we give some existence results of the extremal (greatest and smallest) solutions. Our approach is based on the theories of fixed points, maximal monotone operators and ordered Banach spaces. (C) 2009 Elsevier Ltd. All rights reserved.

: Neuroprotective effects of combined lead and cadmium, as well as N-acetylcysteine, on cerebral cortical neurons following lipid peroxidation injury

: BACKGROUND: Studies have reported the antioxidant effects of lead and cadmium in the central nervous system, but very few have addressed the combined toxicity of lead and cadmium. The mechanisms by which these combined heavy metals are toxic, as well as how to protect cells from these agents, remains poorly understood.OBJECTIVE: Primary cultured rat cortical neurons were used to determine the effects of combined lead and cadmium on levels of glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), catalase (CAT), and acetylcholinesterase (ACNE), as well as malondialdehyde (MDA), and to evaluate the neuroprotective effects of N-acetylcysteine (NAC).DESIGN, TIME AND SETTING: An in vitro toxicological observation was performed at the Comparative Medicine Center of Yangzhou University from August 2007 to April 2008.MATERIALS: Lead acetate, cadmium acetate, and NAC were purchased from Sigma-Aldrich (St. Louis, USA). Commercial kits of GSH-Px, SOD, CAT, ACNE, and MDA were purchased from Nanjing Jiancheng Bioengineering Institute, Nanjing, China.METHODS: The cerebral cortical neurons were isolated from newborn Sprague dawley rats at 24 hours after birth and primary cultured for 6 days. Thereafter, the cells were treated with a range of cadmium doses (0, 5.0, and 10.0 mu mol/L), lead doses (0, 1.0, and 2.0 mu mol/L), or a combination of the two for 12 hours at 37 degrees C in a 5% CO2 incubator, respectively. In addition, the cells were incubated with different doses of cadmium and/or lead and (0 and 50 mu mol/L) NAC for 12 hours to assess the protective effects on cell survival.MAIN OUTCOME MEASURES: The activity of SOD, GSH-Px, CAT, and ACNE, as well as MDA content, in the cell lysates was detected using commercial kits.RESULTS: At 12 hours after treatment, compared to the control group, activity of GSH-Px, SOD, and ACNE in the lead, cadmium, or combined treated cells was significantly decreased with increasing doses of cadmium/or lead (P < 0.05), but CAT activity and MDA levels were significantly increased (P < 0.05). The combination of cadmium and lead led to higher levels of toxicity than individual exposure.CONCLUSION: The degree of oxidative damage increased when the two heavy metals were combined. NAC protected neonatal cortical neurons by increasing activity of anti-oxidative enzymes, and reducing lipid peroxidation, but the reduction was not statistically significant.

: Purpose - The purpose of this paper is to integrate distribut\ed ontologies on the web system and clarify the structure of the integrated oneDesign/methodology/approach - A formal method based on concept lattices is introduced as a mechanism to form more general semantic level. By checking the extension and the intension of concept, this method extracts the concept pairs satisfying inclusion relations from descartes' set of concepts in distributed ontologies first, and then constructs a concept lattice according to these concept pairs An algorithm to reduce redundant relations is also proposed to clarify the structure of integrated ontology.Findings - The experiments demonstrate the effectiveness of the proposed method to reduce redundant relations, and the Nir-to-Ner ratio inclines to 1 05 from 3 13.Research limitations/implications - Instances of certain concept are not given completely on the web, so it is difficult to check extension of different conceptsPractical implications - A very useful method of integrating distributed ontologies on the webOriginality/value Compared with existing methods, this formal method can be performed by program automatically without any human intervening, and can extract the inclusion relations between concepts from distributed ontologies completely.

: In this paper, the interactions of an isoflavone molecule, Genistein (Gen), with Pluronic F127 at different pH values have been investigated using laser light scattering techniques, film analysis methods, UV-vis spectroscopy and transmission electron microscopy. The TEM images and the DSL studies indicate the formation of a Gen/F127 complex induced by the solubilization of Gen in micelles, and the stability of the Gen/F127 complex decreases with the increase of pH. At pH of 6.4, the turbidity of the Gen/F127 complex solution is significantly reduced in the presence of 0.31 mola
