However, conventional abdominal imaging with Cartesian sampling is generally performed during breath-holding to avoid respiratory motion artifact, so the achievable resolution and anatomic coverage of abdominal water/fat separation are limited with typical scan duration of 15-20 sec. This work presents a method for free-breathing abdominal water/fat separation to eliminate the scan time limit and the requirement on patient compliance. To achieve this, the motion-robust radial stack-of-stars 3D gradient echo sequence is used for multiecho acquisition. Different from conventional image based water/fat separation, k-space based water/fat separation which is more suitable for non-Cartesian sampling is used in this work. Chemical shift artifact correction is achieved by modeling the phase accumulation along readout direction in k-space caused by the off-resonance of fat. By modifying the notion of \"field map\" into \"complex field map\", simultaneous R2* estimation is also achieved. Phantom study demonstrates the feasibility of R2* estimation by comparison with the result of T2*-IDEAL method. Results of preliminary in vivo study on healthy volunteers including thigh, knee and abdominal imaging are also shown.","PeriodicalId":327934,"journal":{"name":"International Conferences on Biomedical and Bioinformatics Engineering","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124773608","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Calcium mineralization from MC3T3-E1 pre-osteoblasts (bone-forming cells) on a modified surface of titanium by anodization and electrodeposition of graphene oxide was investigated. Not only graphene oxide coating improves biocompatibility and corrosion resistance, but also anodization of titanium eliminates residuals and reduces the releasing of metal ions. The effects of both surface modifications to calcium deposition and osteopontin expression by osteoblasts were evaluated in this study. Calcium deposited during osteoblast differentiation were observed with alizarin red S (ARS) staining after MC3T3-E1 cells were cultured on polystyrene (PS), graphene oxide coating on polystyrene (GO), anodized titanium (ATi), and graphene oxide coating on anodized titanium (ATiGO) for 14 and 21 days. The concentration of ARS dye was significantly increased when cells were cultured for 21 days onto ATiGO when compared with ATi. Moreover, osteopontin expression was detected with an indirect immunofluorescence staining using flow cytometer after MC3T3-E1 cells were cultured on the samples for 14 days. A relative fluorescence intensity (RFI) of osteopontin in MC3T3-E1 cells on ATiGO was significantly more than that on PS and GO. The results in this study showed that ATiGO increased calcium deposition by and osteopontin expression in osteoblasts, indicating bone formation on the samples.","PeriodicalId":327934,"journal":{"name":"International Conferences on Biomedical and Bioinformatics Engineering","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125326561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The data were analyzed with Wilcoxon Sign Rank Test to verify the alteration. Results: The results of data analyze showed a significant alteration of knowledge, perception, and attitude before and after education by the nurse, by the pharmacist and by the collaboration of nurse and pharmacist (the value of p ≤ 0.05). There was no significant difference level of perception and attitude on in-patient whom educated by pharmacist, nurse, and collaboration of nurse and pharmacist. The significant difference showed on in-patient's knowledge that educated by pharmacist and collaboration of them (p-value 0.025). Conclusion: The results indicated that there was a significantly increased level of knowledge, perception, and attitude on the in-patient that have been educated about the generic drug.

The symptoms of panic disorder are similar with those of mitral valve prolapse, and therefore misdiagnoses often occur. The purpose of this study is to explore the relationship between mitral valve prolapse and panic disorder with the data from Taiwan's National Health Insurance Research Database (NHIRD). There were 15,350 patients of mitral valve prolapse, and 587,735 patients without mitral valve prolapse in this study between 1998 and 2010. Cox-proportional model was used to analyze the association between mitral valve prolapse and panic disorder. This study found that patients with mitral valve prolapse were 1.92 times more likely to have panic disorder than patients without it. Therefore, patients with mitral valve prolapse have a higher risk of panic disorder. As for gender difference, male patients were 0.6183 times more likely to have panic disorder than female patients. It is also found that every one year increase in age increases the risk of illness by 1.0159 times. It is hoped that through the results of this study, patients with mitral valve prolapse will have better care, proper relief, and better quality of life.","PeriodicalId":327934,"journal":{"name":"International Conferences on Biomedical and Bioinformatics Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114346787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, their effects are determined by an ability to penetrate bacterial membranes. Mechanism of reducing permeability of porin channels in Gram-negative bacteria is the least known one among the possible reasons of antibiotic resistance. The adaptive accumulation of lysophosphatidylethanolamine (LPE), which is observed under conditions typical for the parasitic phase (in particular, the availability of glucose) of Gram-negative bacteria Yersinia pseudotuberculsis is accompanied by rearrangements in conformation of outer membrane protein OmpF that may impede the porin channel permeability for ß-lactam antibiotics. In present study, we report that adaptive accumulation of LPE in membranes of Y. pseudotuberculosis grown in the presence of glucose reduces antibacterial effect of ampicillin. In turn, polyphenol extract from buckwheat husks (PEBH) induces both the decrease in the level of LPE and resistance of bacteria to ampicillin. Therefore, PEBH acts synergistically with ampicillin in vivo by lowering its MICs and therefore can be used as antibiotic adjuvant to improve an antibiotic's ability to cross the outer membrane. These results showed that strategies for regulation of adaptive changes in lipid matrix of bacterial membranes is a new potentially effective way to increase the sensitivity of pathogens to known antibiotics.","PeriodicalId":327934,"journal":{"name":"International Conferences on Biomedical and Bioinformatics Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130512902","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
