Antimicrobial Effect of Silver Ionised Water Prepared with the Sintering Coating Method—Effect on Acid Production in Plaque

Purpose: To investigate the effect of silver ionised water on acid production in plaque. Methods: After injecting 0.5 mL of silver ionised water (concentration: 5 ppm) produced with the sintering coating method in the sensor part of the pH metre, plaque collected from the oral cavity by one platinum loop was mixed in. Immediately after that, a 5% sucrose solution (1 g/20 mL) was added and the pH was continuously measured for 30 minutes at 1-minute intervals (A). Similarly, silver ionised water was mixed with 5% sucrose solution in the same way as in (A) at 3 (B), 5 (C), 10 (D) and 15 minutes (E) after plaque contamination. The pH was measured at 1-minute intervals. The pH of the purified water containing no silver ionised water mixed with plaque and sugar solution at the same time was measured and used as a control. Each experiment was conducted three times, and the pH measured every minute was compared as a percentage of the pH at the beginning of the measurement (100%). Results: Analysis of variance of the repeated measurements to determine the effect of silver ionised water on the decrease in pH revealed a main effect of silver ionised water and an interaction between time and group [F(1.302,20.826) = 39.145, p < 0.01]. Multiple comparisons using Dunnett’s method showed a significant decline in the rate of decrease in pH from B to E as compared with that in the control (p < 0.01). Conclusion: Silver ionised water was found to inhibit the acid production in plaque.

Evolutionary Progress:Stephen Jay Gould’s Rejection and Its Critique

In evolutionary theory,we generally believe that the evolution of life is from simple to complex,from single to diverse,and from lower to higher.Thus,the idea of evolutionary progress appears obvious.However,in contemporary academic circles,some biologists and philosophers challenge this idea.Among them,Gould is the most influential.This paper first describes Gould’s seven arguments against evolutionary progress,i.e.,the human arrogance argument,anthropocentric argument,no inner thrust argument,no biological base argument,extreme contingency argument,statistical error argument,and bacteria(other than human beings)ruling the earth argument.Gould’s arguments against evolutionary progress have great influence in contemporary evolutionary theory.Thus,it is necessary to conduct a careful philosophical analysis of each of Gould’s arguments to reveal his philosophical mistakes.This research contends that Gould’s arguments against evolutionary progress are invalid.

Optimizing Reverse Osmosis Membrane Parameters through the Use of the Solution-Diffusion Model: A Review

When designing and building an optimal reverse osmosis (RO) desalination plant, it is important that engineers select effective membrane parameters for optimal application performance. The membrane selection can determine the success or failure of the entire desalination operation. The objective of this work is to review available membrane types and design parameters that can be selected for optimal application to yield the highest potential for plant operations. Factors such as osmotic pressure, water flux values, and membrane resistance will all be evaluated as functions of membrane parameters. The optimization of these parameters will be determined through the deployment of the solution-diffusion model devolved from the Maxwell Stephan Equation. When applying the solution-diffusion model to evaluate RO membranes, the Maxwell Stephan Equation provides mathematical analysis through which the steps for mass transfer through a RO membrane may be observed and calculated. A practical study of the use of the solution-diffusion model will be discussed. This study uses the diffusion-solution model to evaluate the effectiveness of a variety of Toray RO membranes. This practical application confirms two principal hypotheses when using the diffusion-solution model for membrane evaluation. First, there is an inverse relationship between membrane and water flux rate. Second, there is a proportional linear relationship between overall water flux rate and the applied pressure across a membrane.

Dracocephalum palmatum Stephan extract induces apoptosis in human prostate cancer cells via the caspase-8-mediated extrinsic pathway

Dracocephalum palmatum Stephan is a medicinal plant traditionally used by nomadic people in Eastern Russia;however,research on this plant is currently limited.Recently,although studies have been conducted on the constituents of this plant and their antioxidant effects,data on its various pharmacological activities are still lacking.Thus,this study examined the anticancer potential of the dried leaves of D.palmatum S.(DpL)using human prostate cancer PC-3 cells.The antioxidant potential of DpL was evaluated by estimating the total flavonoid and total phenolic content(TFC and TPC,respectively).Additionally,we investigated the effects of the DpL ethyl acetate fraction(DpLE)on cell proliferation,intracellular reactive oxygen species(ROS)generation,apoptosis,and cell cycle arrest in this cell line.The expression levels of superoxide dismutase(SOD)-1,SOD-2,B-cell lymphoma 2(Bcl-2)and Bcl-2 associated X(Bax)ratio,phospho-protein kinase B(p-AKT),cleaved caspase-8,poly adenosine diphosphate(ADP)ribose polymerase(PARP),and cleaved-PARP were evaluated by western blotting.The results indicated that DpLE causes apoptosis and exerts intracellular ROS-independent anticancer effects on prostate cancer cells,associated with increased SOD-2,cleaved caspase-8,and cleaved-PARP expression and inhibited p-AKT signaling.Thus,DpLE may be a potential resource for the development of promising chemotherapeutic agents for prostate cancer.

让资本和市场充分参与到设计中——专访法兰克福展览公司亚洲控股公司董事长鲍思丰Stephan Buurma

有些人说设计师需要基础设施,我觉得他们最需要的是市场,让他们有用武之地的市场。法兰克福展会历史源远流长。1240年,神圣罗马帝国皇帝腓特烈二世批准法兰克福市举办展览会,开办了第一个秋季展览会。到了近代,由于大型展览及文化活动的需要,于1907年开始兴建多功能厅Festhalle,成为当时欧洲最大展馆之一。1909年展馆落成,商人们汇聚新址进行洽商。1919年法兰克福展览公司举办了首个国际法兰克福展览会,到现在已经有近百年的历史。在本届上海设计之都活动周上,我们有幸采访到了法兰克福展览公司亚洲控股公司董事长鲍思丰先生,了解这家有着悠久历史底蕴的公司对于创意与城市发展的认识。
