Endocrinological effects of high-dose Hypericum perforatum extract WS 5570 in healthy subjects
Get PDFIn this single-blind study, the effects of acute oral administration of high-dose Hypericum perforatum extract WS 5570 on the cortisol ( COR), adrenocorticotropic hormone ( ACTH), growth hormone (GH), and prolactin (PRL) secretions were examined in 12 healthy male volunteers. In a randomized order, the subjects received placebo or WS 5570 at several dosages (600, 900, and 1,200 mg) at 08.00 h on 4 different days. After insertion of an intravenous catheter, blood samples were drawn 1 h prior to administration of placebo or WS 5570 ( 600, 900, or 1,200 mg), at the time of administration, and during 5 h thereafter at intervals of 30 min. The serum concentrations of COR, GH, and PRL as well as the plasma levels of ACTH were determined in each blood sample by means of double antibody radioimmunoassay, fluoroimmunoassay, and chemiluminescence immunometric assay methods. The area under the curve value was used as parameter for COR, ACTH, GH, and PRL responses. Repeated-measures Anova revealed a significant stimulatory effect of WS 5570 on the ACTH secretion, whereas COR and PRL secretions were not significantly influenced. Moreover, there was a stimulatory peak of GH release 240 min after challenge with WS 5570 in some but not all volunteers, without reaching statistical significance in comparison with placebo. Mean arterial blood pressure and heart rate remained unchanged after administration of WS 5570. Apparently, WS 5570 at the dosages given in this study inconsistently causes endocrinological effects in healthy subjects by influencing central neurotransmitters. Copyright (C) 2004 S.

MODEL AND VERIFICATION OF WS-CDL BASED ON UML DIAGRAMS
No full text The Web Services Choreography Description Language (WS-CDL) is a specification developed by the W3C and can be viewed as a blueprint for the development of end-point services. Consequently, it is worth providing a systematic approach for its modeling, analysis and verification. The Unified Modeling Language (UML) is an industry standard for modeling. Applying UML to model WS-CDL is obviously a promising solution to bring together academics and practitioners through a unique standard language. In this paper, we propose to use different UML diagrams to model WS-CDL. UML Component Diagram is used to model the underlying structure of WS-CDL. UML Sequence Diagram is utilized to model the activities in WS-CDL. UML State Machine Diagram is utilized to model the behaviors of each role participating in a WS-CDL specification. We then enrich the UML State Machine Diagram with data by the use of UML Class Diagram. Given the UML specification of WS-CDL, we then provide a systematic way of formally analyzing and verifying WS-CDL against desired properties. Some experiments show that our approach can verify structural, behavioral and data properties in a middle-scale data-enriched WS-CDL specification. </jats:p
A Multi‐Functional Separator for Li‐S Batteries: WS₂@C Nanoflowers Catalyze the Rapid Recycling of Lithium Polysulfides by Polar Attraction
Get PDFFeaturing high theoretical capacity, environmental friendliness and low cost, lithium‐sulfur (Li‐S) batteries become promising alternatives to satisfy the growing demand for energy storage. To boost their energy density for practical application, modified separators are needed to suppress shuttle effects resulting from the solubility of lithium polysulfides (LiPSs). Herein, we modified traditional polypropylene (PP) separators with functional WS₂@C nanoflower composites (WS₂@C‐PP). They can effectively adsorb LiPSs and catalyze their conversion on the edge sites of the WS₂. Also, the unique construction of a carbon layer coating on the WS₂ nanoflowers combines active sites and conducting properties. The material benefits the reversibility of redox reactions and reutilization of active materials. With the WS₂@C‐PP separator, the cell displays improved cycling stability and rate performance. When cycling at 0.1 C, the cell discharges a capacity of up to 1475 mAh g⁻¹, and it contributes 943 mAh g⁻¹ originally at 1 C, with a decay rate of only 0.07 % after 500 cycles. Our work highlights the potential of functional separators to advance the properties of Li‐S batteries

Semi-dry mesophilic anaerobic digestion of water sorted organic fraction of municipal solid waste (WS-OFMSW)
No full textAn innovative municipal solid waste separation technology - water separation was developed in China recently. The purpose of this study was to evaluate the feasibility of anaerobic digestion from water sorted organic fraction of municipal solid waste (WS-OFMSW) to methane. A group of bench-scale (35 L) mesophilic (30 +/- 2 degrees C) batch anaerobic digestions were carried out with three total solids in reactor (TSr = 16.0%, 13.5% and 11.0%). The biodegradability of WS-OFMSW with VS/TS of 61.6% was better than that of mechanically sorted OFMSW but still poor than that of source sorted OFMSW. No inhibitions of metal ions, volatile fatty acids and ammonia on anaerobic digestion were found. The reactors with TSr 16.0%, 13.5% and 11.0% achieved methane yield of 273, 283 and 314 L/kgVS and VS removal rate of 26.1%, 35.8% and 41.8%, respectively. The average methane content in biogas was about 66% for all reactors. (C) 2009 Elsevier Ltd. All rights reserved
