journal of Materials Science & Technology 2008年第3期24卷 313-316页

作者： B.H.Kim j.S.shin S.M.Lee B.M.Moon H.D.Kim S.Y.ju O.Y.Choi Advanced Materials R＆D Division Korea Institute of Industrial Technology Incheon 406-840 Korea Tooling Center GM Daewoo Auto ＆ Technology Co. Incheon 403-714 Korea

The effects of Si content on combinations of important properties such as hardness, hardenability, and weldability in addition to strength increment were systematically investigated to develop a Mo and V free low alloy cast steel for automobile cold pressing die insert. For the evaluation of the applicability as the die insert, the mechanical properties were measured after spheroidization annealing （SA）, quenching and tempering （Q/T）, and flame hardening （FH） treatments, respectively. The developed 0.8%-1.6%Si containing Mo and V free alloy cast steels showed excellent matrix strengthening effect, hardenability, and weldability, fulfilling the industrial criterion of the mechanical properties for the die insert.

Photogenerated singlet oxygen over zeolite-confined carbon dots for shape selective catalysis

Science china Chemistry 2019年第4期62卷 434-439页

Singlet oxygen as an activated oxygen species played an important role in organic synthesis. Suitable catalyst for converting ubiquitous oxygen molecule to singlet oxygen under mild conditions has attracted a wide range of attention. Herein, carbon dots have been confined into mesopores of silicalite-1 nanocrystals framework and acted as active sites for generation of singlet oxygen. The high oxygen-adsorption capacity of zeolite nanocrystals facilitated the photocatalytic generation rate of singlet oxygen, outpacing the free-standing carbon dots for 14-fold. The integrated carbon dot-zeolite nanocrystal hybrid also exhibited a special size-dependent selectivity for organic synthesis by using the in situ formed and confined singlet oxygen as active oxygen species.

Legionella dumoffii Tex-KL Mutated in an Operon Homologous to traC-traD is Defective in Epithelial Cell Invasion

Objective To understand the mechanism of invasion by Legionella dumoffii. Methods The L. dumoffii strain Tex-KL was mutated using the Tn903 derivative, Tn903 d IIlac Z. After screening 799 transposon insertion mutants, we isolated one defective mutant. We then constructed the gene-disrupted mutant, KL16, and studied its invasion of and intracellular growth in He La and A549 cells, and in A/j mice survival experiments. The structure of traC-traD operon was analyzed by RT-PCR. Results The transposon insertion was in a gene homologous to Salmonella typhi tra C, which is required for the assembly of F pilin into the mature F pilus structure and for conjugal DNA transmission. Results from RT-PCR suggested that the traC-traD region formed an operon. We found that when the tra C gene was disrupted, invasion and intracellular growth of L. dumoffii Tex-KL were impaired in human epithelial cells. When mice were infected by intranasal inoculation with a tra C deficient mutant, their survival significantly increased when compared to mice infected with the wild-type strain. Conclusion Our results indicated that the traC-traD operon is required for the invasion and intracellular growth abilities of L. dumoffii Tex-KL in epithelial cells.

The Arabidopsis bZIP1 Transcription Factor Is Involved in Sugar Signaling, Protein Networking, and DNA Binding

引用

Molecular Plant 2010年第2期3卷 361-373页

作者： shin Gene Kang john Price Pei-Chi Lin jong Chan Hong jyan-Chyun jang Department of Horticulture and Crop Science The Ohio State University Columbus OH 43210 USA Plant Biotechnology Center The Ohio State University Columbus OH 43210 USA Department of Plant Cellular and Molecular Biology The Ohio State University Columbus OH 43210 USA Department of Biochemistry Gyeongsang National University Jinju Gyeongnam 660-701 Korea

Sugar signaling is a mechanism that plants use to integrate various internal and external cues to achieve nutrient homeostasis, mediate developmental programs, and articulate stress responses. Many bZlP transcription factors are known to be involved in nutrient and/or stress signaling. An Arabidopsis Sl-group bZlP gene, AtbZIP1, was identified as a sugar-sensitive gene in a previous gene expression profiling study （Plant Cell. 16, 2128-2150）. In this report, we show that the expression of AtbZIP1 is repressed by sugars in a fast, sensitive, and reversible way. The sugar repression of Atb- ZIP1 is affected by a conserved sugar signaling component, hexokinase. Besides being a sugar-regulated gene, AtbZIP1 can mediate sugar signaling and affect gene expression, plant growth, and development. When carbon nutrients are limited, gain or loss of function of AtbZlP1 causes changes in the rates of early seedling establishment. Results of phenotypic analyses indicate that AtbZlP1 acts as a negative regulator of early seedling growth. Using gain- and loss-of-function plants in a microarray analysis, two sets of putative AtbZIP1-regulated genes have been identified. Among them, sugar-responsive genes are highly over-represented, implicating a role of AtbZlP1 in sugar-mediated gene expression. Using yeast two-hybrid （Y-2-H） screens and bimolecular fluorescence complementation （BiFC） analyses, we are able to recapitulate extensive C/S1 AtbZlP protein interacting network in living cells. Finally, we show that AtbZIP1 can bind ACGT-based motifs in vitro and that the binding characteristics appear to be affected by the heterodimerization between AtbZlP1 and the C-group AtbZIPs, including AtbZlP10 and AtbZlP63.

Anti-scarring effects of butaprost on human subconjunctival Tenon's fibroblasts

引用

International journal of Ophthalmology(English edition) 2017年第7期10卷 1028-1033页

作者： jong Hoon shin je Hyun Seo jae Ho jung Tae Woo Kim Department of Ophthalmology Pusan National University Hospital Department of Ophthalmology Pusan National University Yangsan Hospital Research Institute for Convergence of Biomedical Science and Technology Pusan National University Yangsan Hospital Department of Ophthalmology Seoul National University College of MedicineSeoul National University Bundang Hospital

AIM： To investigate the toxicity of the E-prostanoid 2（EP2） receptor agonist, butaprost against human subconjunctival（Tenon＇s capsule） fibroblasts, and to determine the underlying mechanism. METHODS： We isolated Tenon＇s fibroblasts from the subconjunctival area of healthy subjects and evaluated the types of EP receptors expressed using quantitative realtime reverse transcription polymerase chain reaction（RTPCR）. The toxicity of butaprost against the fibroblasts was evaluated using methyl thiazolyl tetrazolium and lactic dehydrogenase assays. The inhibition of conjunctival fibroblast proliferation by butaprost was assessed by measuring α-actin levels. The underlying mechanism was assessed by measuring intracellular cyclic adenosine monophosphate（c AMP） levels. Intergroup differences were statistically analyzed using an independent t-test. Densitometry of the Western blot bands was performed using the Image j software. RESULTS： Quantitative real-time RT-PCR revealed that the fibroblast EP2 receptor levels were higher than those of the other EP receptors. Butaprost did not show toxicity against Tenon＇s tissue, but inhibited conjunctival fibroblast proliferation by reducing collagen synthesis. EP2 receptor activation enhanced the c AMP cascade, which might be an important mechanism underlying this ***： Butaprost effectively reduces the subconjunctival scarring response. Given the significanceof wound healing modulation in blebs, butaprost＇s inhibitory effect on subconjunctival Tenon＇s fibroblasts may be beneficial in managing postoperative scarring in glaucoma surgery.
