Neural Regeneration Research 2016年第11期11卷 1760-1761页

作者： Benjamin McMahon elma Aflaki Ellen Sidransky Medical Genetics Branch National Human Genome Research InstituteNational Institutes of Health

Gaucher disease （GD） is a lysosomal storage disorder （LSD） affecting approximately 1 in 50,000 individuals in the general population. Mutations in both alleles of the GBA1 gene result in deficient glucocerebrosidase （GCase） activity, which in turn leads to the accumulation of glycolipid substrates and impaired lysosomal function. GD is a multisystern disorder with a vast spectrum of clinical phenotvpes,

Glycosidically Bound Volatile Compounds of Satureja montana L.,*** Ten.,*** *** Endemic *** SiliC

引用

Advances in Biological Chemistry 2015年第7期5卷 235-238页

作者： Valerija Dunkic Ivana Radovanovic Nada Bezic elma Vuko Department of Biology Faculty of ScienceUniversity of SplitSplitCroatia

In this paper, the glycoconjugated volatile compounds of four Croatian Satureja species (Satureja montana L., S. cuneifolia Ten., S. subspicata Vis. and endemic S. visianii Silic) were investigated. Content and composition of these compounds were examined depending on the stage of plant development. GC and GC–MS analysis of volatile aglycones revealed twenty-one compounds. Thymoquinone, geraniol and carvacrol were detected in all vegetative phases of the investigated plants. Other quantitatively important aglycones were eugenol and thymol of S. montana, phenyl ethyl alcohol, benzene acetaldehyde, borneol, α-terpineol, thymol and eugenol of S. cuneifolia, phenyl ethyl alcohol, benzene acet-aldehyde, terpinen-4-ol, α-terpineol and β-ionone of S. subspicata and camphor, thymol and 8a-acetoxylemolol of S. visianii. Moderate similarity in the chemical composition of essential oils and volatile aglycones of investigated plant species indicate that many biologically active compounds are glycosylated and accumulate as non-volatile glycosides.

“广为流传的串行传输技术和基础设施虽说不可能一夜之间被突然取代,但是背连线板今后仅仅面向串行传输”,国际标准化机构成员以及总线结构和工业网络顾问Hermann Strass先生曾断言。PICMG(CompactPCI)和VITA(VME总线)为由它们标准化了的传输技术准备了解决方案,或者说将它们标准化了。在GHz范围内的处理速度以及高速数据传输速率,要求从机械方面到热管理一直到供电方面做系统的改动。

Synthesis, characterization, and stability of iron (III) complex ions possessing phenanthroline-based ligands

引用

Open Journal of Inorganic Chemistry 2013年第1期3卷 7-13页

作者： Shawnt Tosonian Charles J. Ruiz Andrew Rios elma Frias Jack F. Eichler Department of Chemistry University of California Riverside Riverside USA

It has previously been demonstrated that phenanthroline-based ligands used to make gold metallotherapuetics have the ability to exhibit cytotoxicity when not coordinated to the metal center. In an effort to help assess the mechanism by which these ligands may cause tumor cell death, iron binding and removal experiments have been considered. The close linkage between cell proliferation and intracellular iron concentrations suggest that iron deprivation strategies may be a mechanism involved in inhibiting tumor cell growth. With the creation of iron (III) phen complexes, the iron binding abilities of three polypyridal ligands [1,10-phenanthroline (phen), 2,9-dimethyl-1, 10-phenanthroline (methylphen), and 2,9-di-sec-butyl-1, 10-phenanthroline (sec-butylphen)] can be tested via a competition reaction with a known iron chelator. Therefore, iron (III) complexes possessing all three ligands were synthesized. Initial mass spectrometric and infrared absorption data indicate that iron (III) tetrachloride complex ions with protonated phen ligands (RphenH+) were formed: [phenH][FeCl4], [methylphenH][FeCl4], [sec-butylphenH][FeCl4]. UV-vis spectroscopy was used to monitor the stability of the complex ions, and it was found that the sec-butylpheniron complex was more stable than the phen and methylphen analogues. This was based on the observation that free ligand was observed immediately upon the addition of EDTA to the [phenH][FeCl4] and [methylphenH] [FeCl4] complex ions.

Accuracy of Ebola Information in a Knowledge Exchange Social Website (KESW)

引用

Open Journal of Preventive Medicine 2017年第10期7卷 210-223页

作者： Fiona Gorman Desa Yadegarians Taufa Islam Simon Tongco Esther Johnston elma Estrada Nicholas Gorman California State University Long Beach USA California State University Fullerton USA The Wright Center National Family Medicine Residency at Health Point Auburn USA Keck Graduate Institute Claremont USA

Background: Misinformation on interactive Knowledge Exchange Social Websites (KESWs) is concerning since it can influence Internet users’ health behaviors, especially during an infectious disease outbreak. Objective: The present study seeks to examine the accuracy and characteristics of health information posted to a Knowledge Exchange Social Website (KESW). Methods: A sample of 204 answers to Ebola questions were extracted and rated for accuracy. Multiple logistic regression modeling was used to examine whether answer characteristics (best answer, professional background, statistical information, source disclosed, link, and word count) predicted accuracy. Results: Overall, only 27.0% of the posted answers were rated as “accurate”. Accuracy varied across question topics with between 11.8% - 45.5% of answers being rated as accurate. When Yahoo Answers’ “best answers” were examined, the overall accuracy was substantially higher, with 80.0% of “best answers” being rated as accurate compared to 16.0% of all other answers. Conclusion: There is need for tools to help Internet users navigate health information posted on these dynamic user-generated knowledge exchange social websites.
