The constitution of human is a stable state with the specificity of function and metabolism, which can distinguish one from another during the process that he is born, grow up and senile. This state may usually decide the specialty of physical response, sensitivity to the cause and type of disease. In Western medicine, there is a middle zone between that of disease and that of normal state, whether it can be disease or not. Based on these concept, the constitutional pathology is suggested. The constitution of human is classified into five types in the part of pathology. In this study, a experiment was designed for the scientific access of Chinese constituion theory and constitutional food therapy.

Diao, Qi,Li, Xiaoyang,Diao, Mengxiao,Lee, Yong-Ill,Liu, Hong-Guo Elsevier 2018 JOURNAL OF COLLOID AND INTERFACE SCIENCE - Vol.522 No.-

<P><B>Abstract</B></P> <P><B>Hypothesis</B></P> <P>Our previous studies have shown that the metal nanoparticle/polymer composite structures fabricated at the liquid/liquid interface have good reusability but lower catalytic activity for heterogeneous reactions in aqueous solutions. This should be attributed to the poor water wettability and more compact structure of the polymer matrices. Therefore, it should be possible to improve the catalytic activity through designing and fabricating a porous composite structure with good water wettability.</P> <P><B>Experiments</B></P> <P>A modified liquid/liquid interface adsorption and fabrication method was used. An aqueous solution of copper acetate and a chloroform/DMF mixed solution of PS-<I>b</I>-PAA acted as the two phases. Through spontaneous emulsification, self-assembly of the polymer molecules with Cu<SUP>2+</SUP> ions in the droplets, and adsorption of the formed spherical micelles and nanofibers to the planar liquid/liquid interface, a porous composite microstructure was formed.</P> <P><B>Findings</B></P> <P>This structure consisted of nanofiber-connected nanospheres which have a PS core and a PAA corona. Tiny and well-dispersed Cu nanoparticles were embedded in the hydrophilic corona and were adsorbed on the nanofibers surface as well. After physical cross-linking with 1,6-diaminohexane, the composite material exhibited high catalytic activity and good reusability for the reactions in aqueous solutions. For example, the rate constant for the reduction of <I>p</I>-nitroaniline reached 1965 s<SUP>−1</SUP> g<SUP>−1</SUP>.</P> <P><B>Graphical abstract</B></P> <P>Block copolymer/copper composite microstructure with highly heterogeneous catalytic activity was fabricated successfully at the liquid/liquid interface.</P> <P>[DISPLAY OMISSION]</P>

A Dynamic Evaluation of the Effects of A Free Trade Area of the Americas : An Intertemporal, Global General Equilibrium Model

Diao, Xinshen,Somwaru, Agapi 세종대학교 국제경제연구소 2001 Journal of Economic Integration Vol.16 No.1

This study examines the dynamic effects of a Free Trade Area of the Americas (FTAA) on the countries within the Western Hemisphere. The analysis uses an intertemporal, global, multi-sector general equilibrium model which takes into account changes in saving-investment, capital accumulation, and the linkages between openness in trade and economic growth. The study finds that the developing countries in the hemisphere may not enjoy welfare gain from an FTAA if they trade more with non-hemisphere countries and if trade-diverting effects dominate trade-creating effects. Taking into account the total factor productivity (TFP)-trade linkages, however, all developing countries in the region would benefit from an FTAA. The direct effects of an FTAA on the U.S. and Canada are modest, while the indirect effects of an FTAA, i.e., the effects on U.S. and Canadian firms to invest in their neighboring countries, are strong.

Diao, Chun-Yu,Guo, Hong-Bing,Ouyang, Yu-Rong,Zhang, Han-Cong,Liu, Li-Hong,Bu, Jie,Wang, Zhi-Hua,Xiao, Tao Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.4

Objective: The aim of this study was to screen for possible biomarkers of metastatic osteosarcoma (OS) using a DNA microarray. Methods: We downloaded the gene expression profile GSE49003 from Gene Expression Omnibus database, which included 6 gene chips from metastatic and 6 from non-metastatic OS patients. The R package was used to screen and identify differentially expressed genes (DEGs) between metastatic and non-metastatic OS patients. Then we compared the expression of DEGs in the two groups and sub-grouped into up-regulated and down-regulated, followed by functional enrichment analysis using the DAVID system. Subsequently, we constructed an miRNA-DEG regulatory network with the help of WebGestalt software. Results: A total of 323 DEGs, including 134 up-regulated and 189 down-regulated, were screened out. The up-regulated DEGs were enriched in 14 subcategories and most significantly in cytoskeleton organization, while the down-regulated DEGs were prevalent in 13 subcategories, especially wound healing. In addition, we identified two important miRNAs (miR-202 and miR-9) pivotal for OS metastasis, and their relevant genes, CALD1 and STX1A. Conclusions: MiR-202 and miR-9 are potential key factors affecting the metastasis of OS and CALD1 and STX1A may be possible targets beneficial for the treatment of metastatic OS. However, further experimental studies are needed to confirm our results.

Diao Yong-Fa,Li Xun,Gu Ping-Dao,Li Hao 한국화학공학회 2009 Korean Journal of Chemical Engineering Vol.26 No.3

Numerical simulation was used to research the two-phase flow in the axisymmetric inlet square separator, including the basic flow characteristics, separation efficiency and comparing the difference between single-inlet and double-inlet separator. The effect of the reflecting cone’s geometrical sizes on pressure loss and efficiency was discussed. And the wall erosion condition because of solid particle impingement was calculated and analyzed. The tangential inlet diffuse square separator using RSM modeling that considers anisotropic situation was researched. The distribution of axial, tangential and radial velocity and the pressure loss calculated were analyzed. The results show that there is the typical double deck flow structure in the separator, the square section influences the tangential velocity in the corner, the pressure distribution divides in the inlet on the reflecting cone, and the pressure loss increases with the increase of inlet velocity.

Effects of Serum Addition and Different Culture Media on Growth of Porcine Preantral Follicles In Vitro

Diao, Yun-Fei,Kim, Hong-Rye,Han, Rong-Xun,Kim, Myung-Yoon,Park, Chang-Sik,Jin, Dong-Il The Korean Society of Animal Reproduction 2010 Reproductive & developmental biology Vol.34 No.3

Current developments in IVF and animal cloning have resulted in increasing demand for large quantities of oocytes and ovarian follicles at specific stages of development. These medical and scientific needs may be met by developing an optimal culture system for preantral follicles. In this study, we investigated the growth of porcine preantral follicle cultures in different media and in the presence and absence of serum. Follicles were manually dissected from ovaries obtained from prepubertal gilts at a local slaughterhouse, and cultured for 3 days in M199 or NCSU23 medium supplemented with porcine FSH, transferrin, L-ascorbic acid and insulin. Follicle diameters were measured on day 1 and 3 of culture. In Experiment 1, the effect of supplementing culture medium with fetal calf serum (FCS) on porcine preantral follicle growth was examined. In the group of cultures supplemented with FCS, follicle diameter after 3 days of culture, survival rate and antrum formation rate in the FCS group were significantly higher than those of the control group. In Experiment 2, the effects of culture medium (M199 and NCSU23) on follicle growth were compared. Follicle diameters were increased in the M199 group, compared with those in NCSU23 (p<0.05), but we observed no significant differences in survival and antrum formation rates between cultures grown in the two media. In conclusion, supplementation of the culture medium with serum enhances preantral follicle growth and antrum formation, and M199 is superior to NUSU23 for porcine preantral follicle culture in vitro.

Tribo-Design of Coating/Substrate System

DIAO Dongfeng ENGINEERING TRIBOLOGY RESEARCH INSTITUTE KYUNGPOOK 1999 INTERNATIONAL SYMPOSIUM ON HIGH PERFORMANCE OF TRI Vol.1999 No.-

The design of coatings in tribo -system able to perform well in different wear conditions without lubricants requires a combination of adequate hardness and toughness, good adhesion, a low friction coefficient and a low wear rate. Recently introduced hard coating with interlayers or lubricative particles can be a major step towards the achievement of such coatings in practical usage is their high yielding, Failure and spalling tendency. Therefore, the inhibiting factors in using these coatings for tribo-application are our limited knowledge on the critical stress for the plastic deformation or the fracture. In this paper, three kind of coating/substrate systems(coating without interlayer, coating with an interlayer and coating with particles) in tribo-contact condition were introduced from the point of view of finite element analysis. A theoretical design method for coating/substrate system was given in a series of maps in which the positions of yield initiation and the effect of design factors(coating thickness, yield strenght), as well as, contact factors(contact width, friction coefficient) on the yielding behavior of the coating/substrate system will be pointed out.
