作者： SOO YEON kim SUN YOON SOO mi KWON KYE SOOK PARK YANG CHA LEE-kim Graduate School of Human Environmental Science Department of Food and Nutrition College of Human Ecology Yonsei Health Center Yonsei University 134 Shinchon-dong Sudaemun-ku 120-749 Seoul Korea

Objective To evaluate the effect of 3-month kale （Brassica oleracea acephala） juice supplementation on coronary artery disease risk factors among hypercholesterolemic men. Methods Thirty-two men with hypercholesterolemia （〉 200 mg/dL） were recruited after annual health examinations among the faculty and staff at university. The subjects consumed 150 mL of kale juice per day for a 12-week intervention period. Dietary and anthropometric assessments were performed and blood samples were collected to evaluate biochemical profiles before and after supplementation. Results Serum concentrations of HDL-cholesterol, and HDL- to LDL-cholesterol ratio were significantly increased by 27% （P〈0.0001） and 52% （P〈0.0001）, respectively. The LDL-cholesterol concentration and the atherogenic index were significantly reduced by 10% （P=0.0007） and 24.2% （P〈0.0001）, respectively without affecting body mass index, waist and hip circumferences, or nutrient intakes after three months of supplementation. While there was no difference in the concentration of malondialdehyde, significant increase in glutathione peroxidase activity （P=0.0005） were accompanied by a significant increase in the serum selenium level （P=0.0132）. It was also found that the responses of these risk factors to kale juice administration were dependent on smoking status. Conclusion Regular meals supplementation with kale juice can favorably influence serum lipid profiles and antioxidant systems, and hence contribute to reduce the risks of coronary artery disease in male subjects with hyperlipidemia.

Ever-changing endoscopic treatment for early gastric cancer:Yesterday-today-tomorrow

引用

World Journal of Gastroenterology 2014年第37期20卷 13273-13283页

作者： mi-Young kim Jun-Hyung Cho Joo Young Cho Digestive Disease Center Soonchunhyang University Hospital

Endoscopic resection has been an optimal treatment for selected patients with early gastric cancer(EGC) based on advances in endoscopic instruments and techniques. As endoscopic submucosal dissection(ESD) has been widely used for treatment of EGC along with expanding ESD indication, concerns have been asked to achieve curative resection for EGC while guaranteeing precise prediction of lymph node metastasis(LNM). Recently, new techniques including ESD or endoscopic full-thickness resection combined with sentinel node navigation enable minimal tumor resection and a laparoscopic lymphadenectomy in cases of EGC with high risk of LNM. This review covers the development and challenges of endoscopic treatment for EGC. Moreover, a new microscopic imaging and endoscopic techniques for precise endoscopic diagnosis and minimally invasive treatment of EGC are introduced.

Post-translational modifications （PTMs） of transcription factors play a crucial role in regulating metabolic homeostasis. These modifications include phosphory- lation, methylation, acetylation, ubiqulUnation, SUMOy- lation, and O-GIcnacylation. Recent studies have shed light on the importance of lysine acetylation at nonhis- tone proteins including transcription factors. Acetyla- tion of transcription factors affects subcellular distribution, Dna affinity, stability, transcriptional activity, and current investigations are aiming to further expand our understanding of the role of lysine acetyla- tion of transcription factors. In this review, we summarize recent studies that provide new insights into the role of protein lysine-acetylation in the transcriptional regulation of metabolic homeostasis.

The purpose of this study is to characterize a meta-signature of differentially expressed mRna in chronic kidney disease （CKD） to predict putative microRna （miRna） in CKD-mineral bone disorder （CKD- MBD） and confirm the changes in these genes and miRna expression under uremic conditions by using a cell culture system. PubMed searches using MeSH terms and keywords related to CKD, uremia, and mRna arrays were conducted. Through a computational analysis, a meta-signature that characterizes the significant intersection of differentially expressed mRna and expected miRnas associated with CKD-MBD was determined. Additionally, changes in gene and miRna expressions under uremic conditions were confirmed with human Saos-2 osteoblast-like cells. A statistically significant mRna meta-signature of upregulated and downregulated mRna levels was identified. Furthermore, miRna expression profiles were inferred, and computational anaIyses were performed with the imputed mieroRna regulation based on weighted ranked expression and putative microRna targets （IMRE） method to identify miRnas associated with CKD occurrence. TLR4 and miR-146b levels were significantly associated with CKD-MBD. TLR4 levels were significantly downregulated, whereas pri- miR-146b and miR-146b were upregulated in the presence of uremic toxins in human Saos-2 osteoblast-like cells. Differentially expressed miRnas associated with CKD-MBD were identified through a computational analysis, and changes in gene and miRna expressions were confirmed with an in vitro cell culture system.

Recent advances in genomic medicine have opened up the possibility of tailored medicine that may eventually replace traditional “one-size-fits all” approaches to the treatment of inflammatory bowel disease (IBD). In addition to exploring the interactions between hosts and microbes, referred to as the microbiome, a variety of strategies that can be tailored to an individual in the coming era of personalized medicine in the treatment of IBD are being investigated. These include prompt genomic screening of patients at risk of developing IBD, the utility of molecular discrimination of IBD subtypes among patients diagnosed with IBD, and the discovery of proteome biomarkers to diagnose or predict cancer risks. Host genetic factors influence the etiology of IBD, as do microbial ecosystems in the human bowel, which are not uniform, but instead represent many different microhabitats that can be influenced by diet and might affect processes essential to bowel metabolism. Further advances in basic research regarding intestinal inflammation may reveal new insights into the role of inflammatory mediators, referred to as the inflammasome, and the macromolecular complex of metabolites formed by intestinal bacteria. Collectively, knowledge of the inflammasome and metagenomics will lead to the development of biomarkers for IBD that target specific pathogenic mechanisms involved in the spontaneous progress of IBD. In this review article, our recent results regarding the discovery of potential proteomic biomarkers using a label-free quantification technique are introduced and on-going projects contributing to either the discrimination of IBD subtypes or to the prediction of cancer risks are accompanied by updated information from IBD biomarker research.

Prediction of gas pulsation of an industrial compressor

引用

Journal of Central South University 2013年第10期20卷 2735-2740页

作者： Heuicheol kim mi-Gyung Cho Jaehong Park Cheolho Bai Jaesool Shim School of Mechanical Engineering Yeungnam University Department of Media Engineering Tongmyong University MEMS-Bio Team Korea National NanoFab Center 305 806 Korea

The measurement and prediction of gas pulsations are performed along the discharge pipeline of a reciprocating compressor for a refrigerator. A regression based experimental model of the one-dimensional acoustic field is developed. First, the conventional method for gas pulsation measurement and prediction, which separates the incident and reflected wave of acoustic waves traveling in the frequency domain, is discussed. Then, regression based on our proposed simple model, which is able to predict gas pulsation compared to the conventional method, is introduced for the analysis of a reciprocating compressor(The conventional method requires the value of sound speed in the piping line for the reciprocating compressor). A numerical prediction is made for the regression method. Three power spectrum values along the discharge pipeline are used for analysis, and two values are used for verification. Our results are in a good agreement with the conventional method.
