The association between arterial stiffness parameters, microRNA expression profile from peripheral blood and the extent of coronary artery disease in patients with normal or reduced kidney function
Get PDFAteroskleroza je kronična vnetna bolezen arterij, ki vodi v zoženje svetline žil ter v ishemično okvaro tkiv in organov v povirju prizadetih arterij. Med srčnožilne bolezni uvrščamo ishemično bolezen srca, periferno arterijsko bolezen, bolezni možganskih žil ter anevrizme prsne in trebušne aorte. Predstavljajo enega izmed najpogostejših vzrokov umrljivosti v razvitem svetu in so neposredna posledica napredovale ateroskleroze. Kronična ledvična bolezen je pomemben dejavnik tveganja za srčnožilne bolezni. Arterijska togost označuje zmanjšano podajnost arterij in je povezana s strukturnimi in funkcionalnimi spremembami v žilni steni in pretoku krvi. MikroRNK so ključni epigenetski regulatorji številnih procesov v telesu in imajo velik potencial pri prepoznavanju in zdravljenju srčnožilnih bolezni.
V naši študiji smo analizirali povezave med koronarno arterijsko boleznijo, periferno arterijsko boleznijo in arterijsko togostjo pri bolnikih z in brez kronične ledvične bolezni. Prav tako smo analizirali ekspresijski profil mikroRNK molekul pri bolnikih z najvišjimi in najnižjimi vrednostmi hitrosti karotidno-femoralnega pulznega vala.
Rezultati naše študije dokazujejo, da imajo bolniki s kronično ledvično boleznijo višjo arterijsko togost ter nižji gleženjski indeks. Pri bolnikih s kronično ledvično boleznijo je bilo nekoliko več trožilne koronarne arterijske bolezni, vendar razlika v primerjavi z bolniki brez kronične ledvične bolezni ni bila statistično pomembna.
V ekspresiji mikroRNK razlik ni bilo.Atherosclerosis is a chronic inflammatory disease of the arteries that leads to narrowing of the lumen of blood vessels and ischemic damage to target tissues and organs. The spectrum of cardiovascular disease includes ischemic heart disease, peripheral artery disease, cerebrovascular disease, thoracic and abdominal aortic aneurysms. Cardiovascular disease is one of the most common causes of mortality in the devel-oped world and is a direct consequence of advanced atherosclerosis. Chronic kidney disease is an important risk factor for cardiovascular disease. Arterial stiffness indi-cates decreased arterial distensibility and is associated with structural and functional changes of vascular walls and blood flow. MicroRNAs are key epigenetic regulators of many processes in the body and have great potential in the recognition and treatment of cardiovascular disease.
In our study, we analysed the associations between coronary artery disease, peripheral artery disease and arterial stiffness in patients with and without chronic kidney disease. Additionally, we performed an analysis of microRNA expression in patients with the highest and lowest carotid-femoral pulse wave velocities.
We demonstrated that patients with chronic kidney disease have higher arterial stiffness and decreased ankle-brachial index. More patients with three vessel coronary artery disease had chronic kidney disease, although the difference was not statistically significant. There were no differences in microRNA expression profile between patients with 10 highest and 10 lowest values of carotid-femoral pulse wave velocity
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
