This study was performed to identify how the different levels of nitrogen application affected the variances of gluten properties and end-use qualities and the differences of variances among Korean wheat cultivars. Protein and dry gluten content, SDS sedimentation volume and water absorption of Mixolab increased as nitrogen application increased. This ratio of the increase was higher in Korean wheat cultivars for bread than in Korean wheat cultivars for noodles and cookies. The proportion of（α＋β）-gliadin measured by reversed-phase high-performance liquid chromatography（RP-HPLC） increased, but the proportion of ω-and γ-gliadin decreased as the protein content increased. The Korean wheat cultivars for bread showed a high proportion of（α＋β）-gliadin increase, the Korean cultivars for noodles had a high proportion of γ-gliadin decrease and the Korean wheat cultivars for cookies had a high proportion of ω-gliadin decrease. However, there was no variation of the component in the proportion of glutenin component measured by RP-HPLC, even though the protein content was increased, but all of the protein fractions measured by size exclusion（SE）-HPLC were increased. The soluble monomeric protein showed a high proportion of Korean wheat cultivars for bread by the increase of protein content. Bread loaf volume increased by the increase of protein content but there were no variances in the ratio of increase among Korean wheat cultivars. The cookie diameter decreased with the increase of protein content, and this ratio of decrease was the highest in Korean wheat cultivars for cookies. The hardness of cooked noodles also increased by the increase of protein content but there were no variations in springiness and cohesiveness. The decrease proportion of ω-gliadin affected the increase of bread loaf volume, the hardness of cooked noodles, and the decrease of cookie diameter.

Influence of protein characteristics and the proportion of gluten on end-use quality in Korean wheat cultivars

引用

Journal of Integrative Agriculture 2018年第8期17卷 1706-1719页

作者： Seong-Woo Cho chon-Sik Kang Hyeon Seok Ko Byung-Kee Baik Kwang-min Cho chul Soo Park Department of Crop Science & Biotechnology Chonbuk National University National Institute of Crop Science Rural Development Administration Farm & Agribusiness Management Division Rural Development Administration USDA-ARS CSWQRU Soft Wheat Quality Laboratory Research Center of Bioactive Materials Chonbuk National University

The effects of protein characteristics and the proportion of gluten on end-use quality in 13 Korean wheat cultivars for three years were verified in this study. Year, cultivar, and the interaction between the year and the cultivar influenced protein characteristics, the proportion of gluten except for γ-and ω-gliadin using RP-HPLC(reversed-phase high-performance liquid chromatography), and end-use quality. Protein characteristics and the proportion of gluten in Korean wheat cultivars were between those of Australian standard white(ASW) and hard wheat(AH). Korean wheat cultivars exhibited a higher average α+β gliadin proportion than imported wheat, a γ-gliadin proportion similar to that of dark northern spring wheat, and the same ω-gliadin proportion as AH. They showed a bread-loaf volume intermediate between those of ASW and AH and a texture of cooked noodles similar to that of soft white wheat, but less springiness than imported wheat. The cookie diameter of Korean wheat cultivars was similar to that of hard red winter wheat. There was a correlation between bread-loaf volume and protein characteristics, except for the protein content in Korean wheat cultivars. Springiness and cohesiveness of cooked noodles were not correlated with protein characteristics, while hardness was correlated with the protein content and water absorption of a mixograph. Cookie diameter was negatively correlated with the sodium dodecyl sulfate(SDS) sedimentation volume and water absorption of a mixograph. The end-use quality was not correlated with any proportion of gluten composition. Principal component analysis(PCA) showed that the proportion of gluten was not related to the quality of the bread(both PCs, 81.3%), noodle(77.7%), and cookie(82.4%). PCA explained that Keumkang is suitable for superior bread, while Uri is good for cooked noodles and cookies.

Percutaneous transcatheter closure of mitral paravalvular leak via transarterial retrograde approach

引用

Journal of Geriatric Cardiology 2015年第6期12卷 683-686页

Repeat surgery has usually been considered the first choice to solve paravalvular leaks of prosthetic valves, but it cames a high operative risk, a high mortality rate and an increased risk for re-leaks. Percutaneous closure of such defects is possible, and different approaches and devices are used for this purpose. For mitral paravalvular leaks, constructing an arterio-venous wire loop for delivering the closure device through an antegrade approach is the most commonly used technique. Transcatheter closure can also be performed through a transapical approach or retrograde transfemoral arterial approach. We present a case of 68-year-old man with a mitral paravalvular leak that was suc- cessfully closed using an Amplatzer~ Duct Occluder H, via retrograde transfemoral arterial approach under three-dimensional transesophag- eal echocardiographic guidance, without the use of a wire loop. The initial attempt to cross the paravalvular defect was unsuccessful, but the obstacle was finally overcome by introducing complex interventional techniques.

Web-based interactive visualization of 3D video mosaics using X3D standard

引用

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2006年第7期7卷 1259-1265页

作者： chon Jaechoon LEE Yang-Won SHIBASAKI Ryosuke Center for Spatial Information Science the University of Tokyo 4-6-1 Komaba Meguro Tokyo 153-8505 Japan

We present a method of 3D image mosaicing for real 3D representation of roadside buildings, and implement a Web-based interactive visualization environment for the 3D video mosaics created by 3D image mosaicing. The 3D image mo- saicing technique developed in our previous work is a very powerful method for creating textured 3D-GIS data without excessive data processing like the laser or stereo system. For the Web-based open access to the 3D video mosaics, we build an interactive visualization environment using X3D, the emerging standard of Web 3D. We conduct the data preprocessing for 3D video mosaics and the X3D modeling for textured 3D data. The data preprocessing includes the conversion of each frame of 3D video mosaics into concatenated image files that can be hyperlinked on the Web. The X3D modeling handles the representation of concatenated images using necessary X3D nodes. By employing X3D as the data format for 3D image mosaics, the real 3D representation of roadside buildings is extended to the Web and mobile service systems.

World Journal of Gastroenterology 2006年第7期12卷 1063-1070页

作者： Shu Yang chon Kar Leow Theresa May Chin Tan Department of Biochemistry Yong Loo Lin School of Medicine National University of SingaporeSingapore Department of Surgery Yong Loo Lin School of Medicine National University of Singapore Singapore

AIM： To examine the differences in the responses of normal and cirrhotic livers to partial hepatectomy in relation to the factors influencing liver regeneration.METHODS： Cirrhosis was induced in rats by administration of thioacetarnide. Untreated rats were used as controls. The control rats as well as the cirrhotic rats were subjected to 70% partial hepatectorny. At different time points after hepatectorny, the livers were collected and the levels of cytokines, growth factors and cell cycle proteins were analyzed.RESULTS： After hepatectomy, the cirrhotic remnant expressed significantly lower levels of cyclin D1, its kinase partner, cdk4, and cyclin E as compared to the controls up to 72 h post hepatectomy. Significantly lower levels of cyclin A and cdk2 were also observed while the cdk inhibitor, p27 was significantly higher. In addition, the cirrhotic group had lower IL-6 levels than the control group at all time points up to 72 h following resection.CONCLUSION： The data from our study shows that impaired liver regeneration in cirrhotic remnants is associated with low expression of cyclins and cdks. This might be the consequence of the low IL-6 levels in cirrhotic liver remnant which would in turn influence the actions of transcription factors that regulate genes involved in cell proliferation and metabolic homeostasis during the regeneration process.
