        Chinese Tea Ceremony

        Shu-meng Huang,Jin He 한국차학회 2015 한국차학회지 Vol.- No.S

        Chinese tea ceremony is not only the art of drinking tea, but also a way to spend your lifetime enjoying tea artistically. It is the perfect combinations of aesthetics, literature, painting, calligraphy, and music. We could enjoy teaby smelling, looking, and tasting. Moreover, we could cultivate our tastes in the poetic atmosphere made by drinking tea. It is the material and spiritual enjoyment that we get from tea ceremony. During the long history of Chinese tea culture, people always have been fond of tea ceremony. The aesthetics of Chinese tea ceremony began from Jin Dynasty, but formed at Tang Dynasty eventually. And The Book of Tea written by Lu Yu who was the master of tea in Tang Dynasty was the sign of tea ceremony becoming mature. From ancient times to nowadays, Chinese tea ceremony has great culture accumulations. In Wei and Jin Dynasties, and Tang Dynasty, the Fried Tea was very popular. However, Diancha became popular in the late years of Tang Dynasty and Song Dynasty. Using different hand tricks in Diancha, various strange patterns could be formed on the surface of the tea water. After that, brewing tea replaced the status of Diancha in Ming Dynasty. So Chinese tea ceremony not only has absorbed the essence of Chinese traditional culture, but has kept pace with the times as well. And it has always been loved by royalty, refined scholars, monks and priests. Furthermore, it has also been popular in common people. Chinese Tea ceremony is the treasure of Chinese traditional culture.

        Transcriptome analysis of differentially expressed genes in rabbits’ ovaries by digital gene-expression profiling

        Tao Huang,Ya‑dong Wang,Ming‑ming Xue,Xue Feng,Cai‑Xia Sun,An‑si Wang,Shu‑yu Xie,Meng Zhang,Gui‑Rong Sun,Ming Li 한국유전학회 2018 Genes & Genomics Vol.40 No.7

        Reproduction is a complex physiological process that is regulated by multiple genes and pathways. Compared with studies of common livestock, fewer studies of genes related to the fertility of rabbits (Oryctolagus cuniculus) have been reported, and the molecular mechanism of their high productivity is still poorly understood. To identify candidate genes associated with development and prolificacy in rabbits, we analyzed gene expression differences among the ovaries of mature Californian rabbit (LC), and mature (HH) and immature Harbin white rabbit (IH) using digital gene expression technology. We detected 885 and 321 genes that were significantly differentially expressed in comparisons between HH/IH and HH/LC, respectively. The functions of the differentially expressed genes (DEGs) were determined by GO classification and KEGG pathway analysis. The results suggest that most of the DEGs between the mature and immature developmental stages were predominantly associated with DNA replication, cell cycle, and progesterone-mediated oocyte maturation, and most were up-regulated in the IH group compared with the HH group. The DEGs involved in disparate fecundities between HH and LC were associated with reproduction, fructose and mannose metabolism, steroid hormone biosynthesis, and pyruvate metabolism. Our results will contribute to a better understanding of changes in the regulatory network in ovary at different developmental stages and in different fertility of rabbit.

        A Nano-power Switched-capacitor Voltage Reference Using MOS Body Effect for Applications in Subthreshold LSI

        Zhang, Hao,Huang, Meng-Shu,Zhang, Yi-Meng,Yoshihara, Tsutomu The Institute of Electronics and Information Engin 2014 Journal of semiconductor technology and science Vol.14 No.1

        A nano-power CMOS voltage reference is proposed in this paper. Through a combination of switched-capacitor technology with the body effect in MOSFETs, the output voltage is defined as the difference between two gate-source voltages using only a single PMOS transistor operated in the subthreshold region, which has low sensitivity to the temperature and supply voltage. A low output, which breaks the threshold restriction, is produced without any subdivision of the components, and flexible trimming capability can be achieved with a composite transistor, such that the chip area is saved. The chip is implemented in $0.18{\mu}m$ standard CMOS technology. Measurements show that the output voltage is approximately 123.3 mV, the temperature coefficient is $17.6ppm/^{\circ}C$, and the line sensitivity is 0.15 %/V. When the supply voltage is 1 V, the supply current is less than 90 nA at room temperature. The area occupation is approximately $0.03mm^2$.

      • The Different Expression of Gene Profiles on Hepatocellular Carcinoma Cells with Different Intracellular Hepatitis C Viral Load

        ( Chia-yen Dai ),( Shu-chi Wang ),( Meng-hsuan Hsieh ),( Cheng-fu Yang ),( Ching-i Huang ),( Chung-feng Huang ),( Ming-lun Yeh ),( Jee-fu Huang ),( Wang-long Chung ),( Ming-lung Yu ) 대한간학회 2017 춘·추계 학술대회 (KASL) Vol.2017 No.1

        Aims: The different hepatitis C virus (HCV) replication has been reported among individual hepatocytes in chronic HCV infection by identifying hepatocytes with different HCV RNA levels. We have previously established a fluorescence-activated cell sorting (FACS) protocol to study the effects of different intracellular viral loads in HCV-infected cells. The present study aimed to further study the gene expression on different hepatocellular carcinoma (HCC) cells with different HCV viral load. Methods: The JFH1-EYFP viral florescence intensity was used to sort the high and low viral load cells after 5 days infection in vitro which has been shown in our previous study that infected cells efficiently and accurately discriminated between high- and low-viral load cell populations. The next generation sequence-RNA sequence was used to clarify the mRNA and miRNA gene network between HCV-high and HCV-low infected cells of the HCC cell line. Venn diagram summarizing the probe sets that were differentially expressingbetween the Huh7.5.1 versus each differential viral load cell population and miRDB and miRTar databases were used to predict HVL and LVL/S2 unique miRNA target genes. Results: By analyzing the NGS dataset and miRNA microarray dataset, of the significant transcripts, three miRNA were unique for the LVL/S2 cells and nine miRNA unique for the HVL. Twenty-three miRNA were common for all 3 viral load groups. We verified them by q-PCR and data confirmed the array data expression level. We found that high viral loads were associated with cell inflammation- and cell death-associated pathway; and the low viral loads were associated many stress response- and cell adhesion molecular (CAMs)-related genes. Conclusions: With the established cell sorting protocol, we have demonstrated that different gene network between HCV-high and HCV-low infected cells in JFH1-EYFP infectious cells exists. Our results may provide a boarder gene regulation map between high and low viral load cell populations.

        Development and characterization of a potential diagnostic monoclonal antibody against capsid protein VP1 of the chicken anemia virus

        Yi-Yang Lien,Chi-Hung Huang,Fang-Chun Sun,Shyang-Chwen Sheu,Tsung-Chi Lu,Meng-Shiunn Lee,Shu-Chin Hsueh,Hsi-Jien Chen,Meng-Shiou Lee 대한수의학회 2012 JOURNAL OF VETERINARY SCIENCE Vol.13 No.1

        Chicken anemia virus (CAV) is an important viral pathogen that causes anemia and severe immunodeficiency syndrome in chickens worldwide. In this study, a potential diagnostic monoclonal antibody against the CAV VP1 protein was developed which can precisely recognize the CAV antigen for diagnostic and virus recovery purposes. The VP1 gene of CAV encoding the N-terminus-deleted VP1 protein, VP1Nd129, was cloned into an Escherichia (E.) coli expression vector. After isopropyl-b-D-thiogalactopyronoside induction, VP1Nd129 protein was shown to be successfully expressed in the E. coli. By performing an enzyme-linked immunoabsorbent assay using two coating antigens, purified VP1Nd129 and CAV-infected liver tissue lysate, E3 monoclonal antibody (mAb) was found to have higher reactivity against VP1 protein than the other positive clones according to the result of limiting dilution method from 64 clones. Using immunohistochemistry, the presence of the VP1-specific mAb, E3, was confirmed using CAV- infected liver and thymus tissues as positive-infected samples. Additionally, CAV particle purification was also performed using an immunoaffinity column containing E3 mAb. The monoclonal E3 mAb developed in this study will not only be very useful for detecting CAV infection and performing histopathology studies of infected chickens, but may also be used to purify CAV particles in the future.

        Risk of Death in Colorectal Cancer Patients with Multi-morbidities of Metabolic Syndrome: A Retrospective Multicohort Analysis

        Qingting Feng,Lingkai Xu,Lin Li,Junlan Qiu,Ziwei Huang,Yiqing Jiang,Tao Wen,Shun Lu,Fang Meng,Xiaochen Shu 대한암학회 2021 Cancer Research and Treatment Vol.53 No.3

        Purpose The prevalence of multi-morbidities with colorectal cancer (CRC) is known to be increasing. Particularly prognosis of CRC patients co-diagnosed with metabolic syndrome (MetSyn) was largely unknown. We aimed to examine the death risk of CRC patients according to the multiple MetSyn morbidities.Materials and Methods We identified CRC patients with MetSyn from the electronic medical records (EMR) systems in five independent hospitals during 2006-2011. Information on deaths was jointly retrieved from EMR, cause of death registry and chronic disease surveillance as well as study-specific questionnaire. Cox proportional hazards regression was used to calculate the overall and CRC-specific hazards ratios (HR) comparing MetSyn CRC cohort with reference CRC cohort.Results A total of 682 CRC patients in MetSyn CRC cohort were identified from 24 months before CRC diagnosis to 1 month after. During a median follow-up of 92 months, we totally observed 584 deaths from CRC, 245 being in MetSyn cohort and 339 in reference cohort. Overall, MetSyn CRC cohort had an elevated risk of CRC-specific mortality (HR, 1.49; 95% confidence interval [CI], 1.07 to 1.90) and overall mortality (HR, 1.43; 95% CI, 1.09 to 1.84) compared to reference cohort after multiple adjustment. Stratified analyses showed higher mortality risk among women (HR, 1.87; 95% CI, 1.04 to 2.27) and specific components of MetSyn. Notably, the number of MetSyn components was observed to be significantly related to CRC prognosis.Conclusion Our findings supported that multi-morbidities of MetSyn associated with elevated death risk after CRC. MetSyn should be considered as an integrated medical condition more than its components in CRC prognostic management.

        The Effect of Transformation on the Virulence of Streptococcus pneumoniae

        Xue-Mei Zhang,Yi-Bing Yin,Dan Zhu,Bao-De Chen,Jin-Yong Luo,Yi-Ping Deng,Ming-Fang Liu,Shu-Hui Chen,Jiang-Ping Meng,Kai Lan,Yuan-Shuai Huang,Ge-Fei Kang 한국미생물학회 2005 The journal of microbiology Vol.43 No.4

        Although pneumococcus is one of the most frequently encountered opportunistic pathogen in the world, the mechanisms responsible for its infectiveness have not yet been fully understood. In this paper, we have attempted to characterize the effects of pneumococcal transformation on the pathogenesis of the organism. We constructed three transformation-deficient pneumococcal strains, which were designated as Nos. 1d, 2d, and 22d. The construction of these altered strains was achieved via the insertion of the inactivated gene, comE, to strains 1, 2 and 22. We then conducted a comparison between the virulence of the transformation-deficient strains and that of the wild-type strains, via an evaluation of the ability of each strain to adhere to endothelial cells, and also assessed psaA mRNA expression, and the survival of hosts after bacterial challenge. Compared to what was observed with the wild-type strains, our results indicated that the ability of all of the transformation-deficient strains to adhere to the ECV304 cells had been significantly reduced (p < 0.05), the expression of psaA mRNA was reduced significantly (p < 0.05) in strains 2d and 22d, and the median survival time of mice infected with strains 1d and 2d was increased significantly after intraperitoneal bacterial challenge (p < 0.05). The results of our study also clearly indicated that transformation exerts significant effects on the virulence characteristics of S. pneumoniae, although the degree to which this effect is noted appears to depend primarily on the genetic background of the bacteria.
