Wood biochemicals for the protection of health. Focus on hemicellulose, stilbenoids and lignans
Get PDFTrees produce an enormous amount of compounds that are still scantly utilized.However, the results obtained from structurally similar biochemicals suggest that wood-derived compounds could be used for the protection of health in various applications. Polyphenols, for instance, could be extracted from wood in high quantities. Similar polyphenols to those in wood include resveratrol, found in grapes, and secoisolariciresinol, present in flaxseeds. Their consumption has been inversely associated with the incidence of various diseases, especially certain cancers and obesity-related disorders.
The aim of this study was to determine the health-promoting effects of woodderived biochemicals. The effect of spruce hemicellulose on the growth of probiotic intestinal bacteria was studied. The results suggest that the bifidobacteria and lactobacilli can utilize hemicellulose and thus it has potential as a prebiotic compound.
In particular, the efficacy of pine polyphenols to inhibit the growth of prostate cancer was our main interest. It was found that stilbenoids and lignans inhibited the proliferation of various cancer cells, and reduced the growth of prostate cancer xenografts in mice. The polyphenol rich pine knot extract was well tolerated in diet and extract-derived polyphenols were rapidly absorbed after intake. Furthermore, we determined the effect of the dietary pine knot extract on the weight gain and the expression of aromatase gene in reporter mouse expressing the promoter region of a human aromatase gene. It was found that dietary pine knot extract alleviated the obesity-induced inflammation in adipose tissue and downregulated the expression of a human aromatase gene.
Taken together, several components of spruce and pine may have a future role as health-promoting compounds.Siirretty Doriastaei tietoa saavutettavuudest
Antifasistinen Glasgow Celtic : Celtic FC:n ja sen kannattajien näkemykset jalkapalloseuran poliittisuudesta Israelin ja Palestiinan konfliktin yhteydessä
No full textLokakuun 7. päivänä vuonna 2023 Israelin ja Palestiinan välillä vuosikymmeniä konfliktintäyteisenä elänyt tilanne koki tuoreimman eskalaationsa. Myöhemmin samana päivänä glasgowlaisen jalkapalloseura Celtic FC:n kannattajaryhmä Green Brigade nosti Skotlannin valioliigan ottelussa Celtic-Kilmarnock katsomossa esille banderollin, jossa ilmaistiin tukea Palestiinalle. Celtic tuomitsi kannattajien toiminnan ja julkaisi tiedotteen, jossa julistettiin, että Celtic ei ole poliittinen organisaatio, vaan jalkapalloseura.
Tämän tutkielman tarkoituksena on käsitellä Celtic FC:n ja sen kannattajien näkemyksiä jalkapalloseuran poliittisuudesta seuraaviin tutkimuskysymyksiin nojaten: 1) Miten Celtic FC ja sen kannattajat ymmärtävät poliittisuuden? 2) Millainen poliittinen toimija kannattajaryhmä Green Brigade on? 3) Miten Green Brigadeen kuulumattomat Celtic-kannattajat suhtautuvat Green Brigaden poliittisiin toimiin? Tämän tarkastelemiseksi olen kohdistanut laadullisen sisällönanalyysin aineistoon, joka koostuu Celtic FC:n kahdesta lokakuussa 2023 julkaisusta tiedotteesta, yhdestä kannattajaryhmä Green Brigaden lokakuussa 2023 julkaisemasta tiedotteesta, sekä Kerrydale Street -sivuston Supporters Thread -keskusteluketjun viesteistä lokakuun 2023 7. ja 10. päivien väliseltä ajalta.
Tutkielman tulokset osoittavat, että Celtic FC:n kannattajat ymmärtävät seuran poliittisena toimijana. Tämä kumpuaa esimerkiksi seuran historiallisesta taustasta, sekä seuran aiemmista toimista eri poliittisiin kysymyksiin liittyen. Seuran virallisesti linjaama näkemys poikkeaa kannattajien tulkinnasta, yrittäen Palestiinann tukemisen katsotun arkaluontoisuuden vuoksi ottaa kysymykseen etäisyyttä. Kannattajien näkemys edustaa aspektiteoreettista politiikkakäsitystä, siinä missä Celticin seuran ilmaisema näkemys myötäilee sektoriteoreettista politiikkakäsitystä.unknown accessibilityei tietoa saavutettavuudest
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
