Jeffrey Yu,Jun Lian,Ruei-Hong Li,Chen-Sin Hung,Dong-Tai Chen,Yu-Kai Chang 대한운동학회 2024 아시아 운동학 학술지 Vol.26 No.1

Objectives In the past centuries, the concept of “physical education” has changed from a more general concepts including physical activities and sports, to specifically inferring “instruction of physical activity”. Instead, “sports” has become the comprehensive concept of sports, exercise, and physical education. Given to the inconsistent terminologies and English translations of “體育 (ti-yu)” (physical education) and “運 動 (yun-dong)” (sports or exercise) in Mandarin, the purpose of this study was to investigate in the current terminology usage, hierarchy, and the English translation of “體育 (ti-yu)” and “運動 (yun-dong)” in Taiwan. Met hods Three government authorities, two sport related universities, eight top sport and exercise journals, and nighty-six college departments in Taiwan were analyzed. Results “運動 (yun-dong)” was the most widely used terminology as “體育 (ti-yu)” occupied the majority usage among government authorities, sport related universities, and title of top sport and exercise journals. Regarding English translation, despite of “department of physical education”, “sports” remained the most common terminology. Moreover, “體育 (ti-yu)” and “sports” are the highest hierarchy among government authorities, and sport related university; “體育 (ti-yu)” and “physical education” are the highest hierarchy among traditional sport and exercise journals; “運動 (yun-dong)” and “sports” are the highest hierarchy among college departments also the mainstream of current translation and hierarchy. Conclusions “體育 (ti-yu)” was the highest hierarchy in the past. However, “運動 (yun-dong)” has been the mainstream of the highest hierarchy in Mandarin according to college departments. In English, “sport(s)” is the main term in Taiwan when translating “體育 (ti-yu)” and 運動 (yun-dong)”, also being the highest hierarchy. On the other hand, “體育 (ti-yu)” and “physical education” are utilized regarding those departments focusing on educating PE teachers. This study expects the terminology, English translations, and hierarchy being align with the mainstream of current translation and hierarchy in the future.

Yu-lian Jiang,Yuanchun Li,Shen-quan Wang 제어·로봇·시스템학회 2017 International Journal of Control, Automation, and Vol.15 No.6

For networked control systems consisting of multiple simple-pendulums driven by corresponding DCmotors with time-varying communication and input delays, a distributed coordinated controller via observer-basedoutput feedback is designed to solve the tracking problem under both fixed and jointly-connected switching topologies. Firstly, the linearized dynamic model for multiple nonlinear simple-pendulum network systems with DCmotors is presented, and the distributed coordinated tracking problem considering time-varying input delays ismathematically described. Then the distributed observer-based tracking control protocol with time-varying communicationand input delays is proposed, and simultaneously, both the observer gain and feedback gain are designed. Two examples are simulated to demonstrate consensus tracking for three types of states, i.e., swing angles, angularvelocities of multiple simple-pendulums and armature currents of DC motors can be completed utilizing thedeveloped coordinated tracking control with fixed and jointly connected topologies.

Lian, Yu-Ji,Lim, Hak-Tae The Korean Society of Plant Biotechnology 2001 Plant molecular biology and biotechnology research Vol.3 No.1

New types of cytoplasmic male sterility in Brassica species would be very useful for the production of F$_1$, hybrid seeds. Leaves and stems of rapid cycling stock of B.juncea (CrGC4-3) containing Anand CMS were used as experimental materials for plant regeneration from protoplast culture. Very high plant regeneration rate (85%) was found in the Kao & Michayluk medium supplemented with 2 mg/L zeatin, 0.5 mg/L BAP, and 1 mg/L NAA when only leaf, not stem, segments were cultured. Protoplasts were isolated from leaves using mixtures of enzymes (1% Cellulycin, 0.5% Macerozyme) in 0.4 M mannitol and 50 mM $CaCl_2$.$2H_2$O. Mcrocalli induced from protoplasts were transferred to the shoot regeneration medium containing 2 mg/L BAP, 2 mg/L zeatin, and 0.5 mg/L NAA. After 60 days of initial protoplast culture, regenerated plantlets were obtained, acclimatized, transplanted into the pots, and grown up to the flowering stage.

Lian Yu Guo,Xing Fu Cai,Jung Joon Lee,강삼식,신은명,Hong Yu Zhou,Ji Won Jung,김영식 대한약학회 2008 Archives of Pharmacal Research Vol.31 No.4

Demethoxycurcumin and bisdemethoxycurcumin are the main active ingredients isolated from Curcumae Longae Radix. Recent studies demonstrated that both compounds exhibit antioxidative and anti-inflammatory effects as well as effects on cancer cell lines. In this study, we compared the activities of demethoxycurcumin and bisdemethoxycurcumin, and both compounds were evaluated on lipopolysaccharide (LPS)-induced nitric oxide (NO) production, inducible nitric oxide synthase (iNOS), cycloxygenase-2 (COX-2) and nuclear factor-kappaB (NF-κB) activity in a RAW 264.7 macrophage cell line. The evaluation:results suggested that the anti-inflammatory properties of demethoxycurcumin and bisdemethoxycurcumin were attributed to the inhibition of iNOS and COX-2 expression, as initiated by the inhibition of NF- κB activity. Additionally, both of them significantly inhibited carrageenan-induced paw edema in mice. Taken together, all of the results showed that the suppressive effect of demethoxycurcumin was stronger than that of bisdemethoxycurcumin, indicating that the methoxy group had enhanced demethoxycurcumin’s anti-inflammation effects.

Lian Yu Guo,Tran Manh Hung,배기환,김영식,Sehyun Jang,신은명,Ji Won Chung,강삼식,김현표 대한약학회 2009 Archives of Pharmacal Research Vol.32 No.3

Schisandrin is the main active ingredient isolated from Schisandra chinensis Baill. Recent studies have demonstrated that schisandrin exhibits anti-inflammatory effects in vivo and in vitro. In this study, we examined whether the order of lipopolysaccharide (LPS) treatment affects the mechanism of schisandrin anti-inflammatory activity. We found that the antiinflammatory mechanisms are not the same depending on whether macrophages were treated with schisandrin before or after LPS. The main difference is that inhibitor kappaBα (IκBα) degradation was not inhibited when macrophages were pretreated by LPS before schisandrin and was weakly inhibited when macrophages were pretreated by schisandrin before LPS.

Cimiside E Arrests Cell Cycle and Induces Cell Apoptosis in Gastric Cancer Cells

Lian Yu Guo,Eun Ji Joo,손건호,Su Jin Jeon,Sehyun Jang,신은명,Hong Yu Zhou,Yeong Shik Kim 대한약학회 2009 Archives of Pharmacal Research Vol.32 No.10

Cimiside E was isolated from the Cimicifuga heracleifolia Komarov extract, which has been previously demonstrated to possess apoptotic action on gastric cancer cells. The IC50 value of cimiside E on gastric cancer cells for 24 h was 14.58 μM. The mechanism of apoptosis was further elucidated through western blot, RT-PCR, morphology, Annexin V-FITC/PI staining and cell cycle analysis. Cell cycle arrest was induced by cimiside E in S phase at a lower concentration (30 μM) and G2/M phase at higher concentrations (60 and 90 μM). Cimiside E mediated apoptosis through the induction of the caspase cascade for both the extrinsic and intrinsic pathways. These findings suggest that cimiside E may be an effective chemopreventive agent against cancer.

A New Quorum-Sensing Inhibitor Attenuates Virulence and Decreases Antibiotic Resistance in Pseudomonas aeruginosa

Yu-Xiang Yang,Zhen-Hua Xu,Yu-Qian Zhang,Jing Tian,Li-Xing Weng,Lian-Hui Wang 한국미생물학회 2012 The journal of microbiology Vol.50 No.6

Quorum sensing (QS) has been a novel target for the treatment of infectious diseases. Here structural analogs of Pseudomonas aeruginosa autoinducer N-acyl homoserine lactone (AHL) were investigated for QS inhibitor (QSI) activity and a novel QSI was discovered, N-decanoyl-L-homoserine benzyl ester (C2). Virulence assays showed that C2 downregulated total protease and elastase activities, as well as the production of rhamnolipid, that are controlled by QS in P.aeruginosa wild-type strain PAO1 without affecting growth. C2 was also shown to inhibit swarming motility of PAO1. Using a microdilution checkerboard method, we identified synergistic interactions between C2 and several antibiotics, tobramycin, gentamycin, cefepime, and meropenem. Data from real-time RT-PCR suggested that C2 inhibited the expression of lasR (29.67%), lasI (21.57%), rhlR (28.20%), and rhlI (29.03%).

Yu-Lian Zhang,신현재,이정헌,이지은 대한이비인후과학회 2019 Clinical and Experimental Otorhinolaryngology Vol.12 No.2

Objectives. The extract of Hizikia fusiformis is known to exhibit anticancer, antiatopic and antioxidant activities. We aimed to investigate the extract of H. fusiformis on allergic rhinitis inflammation in a mouse model. Methods. The 4-week-old BALB/c mice were randomly assigned into four groups: group A, control group (n=9); group B, allergic rhinitis group (n=10); group C (n=10) received 300 mg/kg of H. fusiformis during nasal challenging period; group D (n=10) received 600 mg/kg of H. fusiformis during general sensitization period and 300 mg/kg of H. fusiformis during nasal challenging period. Allergic inflammation was made with ovalbumin (OVA) and alum then challenged intranasally with OVA. H. fusiformis was intraperitoneally administered 3 hours before the OVA administration. Allergic symptom score and the levels of immunoglobulin G1 (IgG1), IgG2a, OVA-specific IgE antibodies, levels of cytokines in the nasal mucosa and in spleen cell culture supernatant, such as tumor necrosis factor alpha (TNF-α), interleukin 4 (IL-4), IL-5, IL-13, and IL-10 were assessed. The percentage of regulatory T cell was analyzed by flow cytometry. Eosinophilic infiltration and goblet cell hyperplasia were also evaluated. Results. H. fusiformis administered groups C and D showed significant inhibitory effects on nasal symptoms, IL-13 mRNA expression and eosinophil infiltration/goblet cell hyperplasia in the nasal tissue; OVA-specific IgE production in serum (P<0.05). In group D, H. fusiformis treatment downregulated IL-4, IL-5, IL-13, TNF-α, and IL-10 cytokine expression in splenocyte culture as well as significantly decreased IgG2a, IgG1 levels in serum compared with group B (P<0.05). However, the expressions of IL-5, interferon-γ and forkhead box P3 mRNA did not change in groups C and D. Conclusion. H. fusiformis could induce antiallergic inflammation by suppressing the T-helper type 2 cytokine production (IL-13) locally and systemically, OVA-specific IgE formation, goblet cell hyperplasia, and eosinophilic infiltration in a mouse model of allergic rhinitis. Thus, H. fusiformis could be considered as a potential therapeutic agent in treating allergic rhinitis.

TAZ as a novel regulator of oxidative damage in decidualization via Nrf2/ARE/Foxo1 pathway

Yu Hai-Fan,Zheng Lian-Wen,Yang Zhan-Qing,Wang Yu-Si,Wang Ting-Ting,Yue Zhan-Peng,Guo Bin 생화학분자생물학회 2021 Experimental and molecular medicine Vol.53 No.-

TAZ, as a crucial effector of Hippo pathway, is required for spermatogenesis and fertilization, but little is known regarding its physiological function in uterine decidualization. In this study, we showed that TAZ was localized in the decidua, where it promoted stromal cell proliferation followed by accelerated G1/S phase transition via Ccnd3 and Cdk4 and induced the expression or activity of stromal differentiation markers Prl8a2, Prl3c1 and ALP, indicating the importance of TAZ in decidualization. Knockdown of TAZ impeded HB-EGF induction of stromal cell proliferation and differentiation. Under oxidative stress, TAZ protected stromal differentiation against oxidative damage by reducing intracellular ROS and enhancing cellular antioxidant capacity dependent on the Nrf2/ARE/Foxo1 pathway. TAZ strengthened the transcriptional activity of Nrf2 which directly bound to the antioxidant response element (ARE) of Foxo1 promoter region. Additionally, silencing TAZ caused accumulation of intracellular ROS through heightening NOX activity whose blockade by APO reversed the disruption in stromal differentiation. Further analysis revealed that TAZ might restore mitochondrial function, as indicated by the increase in ATP level, mtDNA copy number and mitochondrial membrane potential with the reduction in mitochondrial superoxide. Additionally, TAZ modulated the activities of mitochondrial respiratory chain complexes I and III whose suppression by ROT and AA resulted in the inability of TAZ to defend against oxidative damage to stromal differentiation. Moreover, TAZ prevented stromal cell apoptosis by upregulating Bcl2 expression and inhibiting Casp3 activity and Bax expression. In summary, TAZ might mediate HB-EGF function in uterine decidualization through Ccnd3 and ameliorate oxidative damage to stromal cell differentiation via Nrf2/ARE/Foxo1 pathway.

‘그러니까’의 담화화용적 기능 연구

( Lian-yu Piao ) 한국언어문화교육학회 2012 언어와 문화 Vol.8 No.1

In a foreign language learning, acquisition of discourse-pragmatic features is not easy, comparing to the acquisition of grammar functions. While a conjunctive adverb ‘Therefore’ in Korean language has a grammar function connecting sentences, it also functions as various discourse markers in a real world situation. However, Korean textbooks currently in use are only suggesting ‘therefore’ as a meaning of ‘reason·cause’, which is different from the case of Korean native speakers who use ‘therefore’ as of a discourse marker in spoken language. Considering this, it is essential to include ‘therefore’ as a discourse marker for language teaching. If discourse-pragmatic features of ‘therefore’ are accurately interpreted and also its rule is taught to leaners, then Korean language learning can be more efficiently accomplished.
