  • Five compounds of iridoids, lignan and phenylpropanoid glycosides were isolated from the roots of Valeriana jatamansi by column chromatography. Their structures were elucidated as 11-methoxyviburtinal (1), baldrinal (2), prinsepiol-4-O-${\beta}$-D-glucoside (3), coniferin (4), and hexacosanic acid (5) by spectroscopic analysis. 11-Methoxyviburtinal was a new compound, and others were isolated from the plant for the first time.

  • We fabricated $(Li_{0.5-x}Na_xLa_{0.5})Ti_{0.8}Zr_{0.2}O_3$(LNTLZ)ceramics ($0{\leq}x{\leq}0.4$) with a perovskite structure via standard solid state synthesis. The influence of Na content on the structural and electrical properties of LNTLZ ceramics was also investigated. During XRD patterns analysis, all of the samples showed orthorhombic structure. The resistance of LNTLZ ceramics decreased as Na content increased, and the maximum activation energy shows 0.56 eV at x=0.4 at room temperature. These results indicated that LNTLZ ceramics are a candidate for use Lithium ion batteries as electrolytes.

  • Polystyrene superstructure films show faint rainbow color, and this low color saturation limits its wide application. In this paper, polystyrene superstructure films with single bright blue color were prepared by vertical deposition self-assembly method using polystyrene microspheres with average diameter of $310{\pm}10nm$ as raw material. Polystyrene superstructure films were modified by adding nano-carbon powder, and effect of the amount of nano-carbon powde on color performance was studied. The results showed that without addition of nano-carbon powder, the superstructure films showed a faint rainbow color, while with addition of nano-carbon power, the superstructure films exhibited a single bright blue under the same natural light source. Changing the amount of nano-carbon powder addition could adjust color saturation of the film. With increasing the amount of nano-carbon powder addition from 0.008 wt% to 0.01 wt%, color saturation of the superstructure film increased gradually. Further increasing the amount of nano-carbon powder addition to 0.011wt%, color saturation of the superstructure film didn't increase anymore and tended to get dark.

  • The aim of the present study was to investigate the development of theory of the deficiency of yin-yang in the spleen-stomach(脾胃). The spleen-stomach theory is a very valuable composition of the oriental medicine. Its first theoretical basis was established by Li Dong Yuan(李東垣) who wrote Piweilun("脾胃論"). He insisted the importance of spleen yang(脾陽) which is the "postnatal base of life" by transforming and transporting of food essence and fluids and raises the clear. After him, his theory had influenced many descendant medical men. one of them, Ye Tian Shi(葉天士) found out the differences of between stomach and spleen. Especially he focused on the stomach yin(胃陰) which is easy to be exhausted by dry-fire(燥火). And he also made another remedy, "the stomach yang should be moved well(宣通胃陽)", which emphasize on that cold and stagnant cause the deficiency of the stomach yang. After that, spleen yin(脾陰) theory was set up by Tang Zong Hai(唐宗海). His spleen yin(脾陰) was deeply related with digestive enzymes and pancreas, because his theory was established by comparing oriental and western medicine. These four theories became the theoretical basis of the deficiency of yin-yang in the spleen-stomach(脾胃), and similar symptom of the spleen-stomach(脾胃) could be categorized according to the pattern identification(辨證) which was developed from these four theory.

  • This study aimed to find the possibility of interactions between the Doctrine of the Mean and evolutionary biology. Between the two disciplines, there exists a huge gap such as "traditional era vs. modern times" and "humanities vs. natural science." However, this paper assumed that an analysis of their similarities and differences would allow us to find the possibility for them to interact and communicate with each other. For this purpose, the author proposed a three-step approach to studies of the following topics: human nature in step 1, validity of reasons to live in step 2 and biologically affinitive relations in step 3. The present study in step 1 pays attention to the similarities and differences between genes and in-ui-ye-ji (a set of four Confucian values: benevolence, righteousness, propriety and wisdom). This step discusses the issues of ri (principle) and ki (generative force) in Zhu Xi's theory vs. genes and vehicles in evolutionary biology, innate goodness vs. altruism of genes and in-ui-ye-ji vs. epigenetic rules. In step 2, attention is paid to the similarities and differences between natural selection and shi zhong (時中). They are discussed in terms of the upset of the law of nature vs. mutation, changes vs. evolutions and shi zhong vs. natural selection/adaptation. Step 3 focuses on the similarities and differences between species diversity and li-yi-fen-shu (one li and its many aspects). The discussion in this step addresses the issues of part or whole vs. li-yi-fen-shu, biological affinity vs. single energy and ecosystem vs. "the earth moves orderly, and everything thereon flourishes." If these studies are conducted as planned, a new direction can be set for Zhu Xi's neo-Confucianism. Further, the interaction between humanities and natural science will pave the way for us to overcome asymmetry between different disciplines.

  • In this study, the electrochemical behavior of Sm on the binary liquid Al-Ga cathode in the LiCl-KCl molten salt system is investigated. First, the co-reduction process of Sm(III)-Al(III), Sm(III)-Ga(III), and Sm(III)-Ga(III)-Al(III) on the W electrode (inert) were studied using cyclic voltammetry (CV), square-wave voltammetry (SWV) and open circuit potential (OCP) methods, respectively. It was identified that Sm(III) can be co-reduced with Al(III) or Ga(III) to form AlzSmy or GaxSmy intermetallic compounds. Subsequently, the under-potential deposition of Sm(III) at the Al, Ga, and Al-Ga active cathode was performed to confirm the formation of Sm-based intermetallic compounds. The X-ray diffraction (XRD) and scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS) analyses indicated that Ga3Sm and Ga6Sm intermetallic compounds were formed on the Mo grid electrode (inert) during the potentiostatic electrolysis in LiCl-KCl-SmCl3-AlCl3-GaCl3 melt, while only Ga6Sm intermetallic compound was generated on the Al-Ga alloy electrode during the galvanostatic electrolysis in LiCl-KCl-SmCl3 melt. The electrolysis results revealed that the interaction between Sm and Ga was predominant in the Al-Ga alloy electrode, with Al only acting as an additive to lower the melting point.

  • GST pull-down assays were used to characterize the SARS-CoV membrane (M) and nucleocapsid (N) interaction, and it was found that the amino acids 211-254 of N protein were essential for this interaction. When tetrad glutamines (Q) were replaced with glutamic acids (E) at positions of 240-243 of the N protein, the interaction was disrupted.

  • Automatic image completion techniques have difficulty processing images in which the target region has multiple planes or is non-facade. Here, we propose a new image completion method that uses belief propagation based on planar priorities. We first calculate planar information, which includes planar projection parameters, plane segments, and repetitive regularity extractions within the plane. Next, we convert this planar information into planar guide knowledge using the prior probabilities of patch transforms and offsets. Using the energy of the discrete Markov Random Field (MRF), we then define an objective function for image completion that uses the planar guide knowledge. Finally, in order to effectively optimize the MRF, we propose a new optimization scheme, termed Planar Priority-belief propagation that includes message-scheduling-based planar priority and dynamic label cropping. The results of experiment show that our approach exhibits advanced performance compared with existing approaches.

  • Objectives The purpose of this study is to investigate recent clinical studies on the effect of acupuncture on sore throat. Methods Based on the PubMed search with the key search terms of 'sore throat, acupuncture', dated from 1992 to 2015, 7 controlled trials and 8 case series was found, and were analyzed for this study. Results 1. The most commonly used acupoints were Quchi (LI11), and Hegu (LI4). 2. The most commonly used meridians were The Lung Meridian of Hand-Taiyin and The Large Intestine Meridian of Hand-Yangming. 3. Acupuncture treatment was effective for both acute and chronic sore throat. 4. More clinical studies are needed to prove the effectiveness of the acupuncture on sore throat. To be more objective on the study results, we can measure temperature drops on or amount of analgesic consumption for sore throat after acupuncture treatment.
