The Androgen Receptors expression in Anguilla Japonica Liver and Ovary in Vitro
No full text中文摘要
在日本鰻人工催熟的策略中使用外源性荷爾蒙(salmon pituitary homogenate, SPH)，可以使之生殖成熟達到排卵，另一方面SPH與雄性激素共同注射的鰻魚，在本實驗室研究成果中，發現有更多顯著的優點，如卵數較多、卵發育較為同步等優點。性荷爾蒙，如雄性激素扮演一部分在於腦部，下視丘與腦下腺的回饋作用等。在本實驗室過去的外源性注射鰻魚研究當中，以SPH與雄性激素催熟，卻尚未能了解雄性激素如何在卵巢與肝臟進行作用，本實驗因而在日本鰻人工催熟的早期，採用離體組織培養的方式分別探討SPH與雄性激素單一與相加對於肝臟與卵巢，雄性激素接受器(androgen receptor, AR)，雌性激素接受器(estrogen receptor, ER)與卵黃前質(vitellogenin, Vg)的表現，透過測定雄性激素接受器來呈現雄性激素對於卵巢與肝臟的影響，並且觀察雄性激素接受器如何表現，在本篇研究中發現以SPH注射一針的日本鰻，ARs與ER之表現量提升，在使用雄性激素離體培養的日本鰻卵巢與肝臟中，ARs與ER表現量皆有提高，並且在卵巢中增加follicle-stimulating hormone receptor, FSHR的表現量；然而以SPH注射一針持續使用SPH培養的組別卻使ARs與ER之表現量下降。在日本鰻的人工催熟中持續注射SPH可以使鰻魚青春發育完成並且達到最後的成熟，持續的SPH可能於早期會抑制其雄性激素接受器或是其他接受器的表現量，可能使Vg生成量降低，進而影響卵質。本篇實驗藉由離體培養，印證了過去的使用SPH與雄性激素催熟，在人工催熟早期，雄性激素不僅只進行回饋作用，在肝臟與卵巢扮演了不可或缺的角色，提升雄性激素接受器的表現，肝臟中vitellogenesis與卵巢中FSHR的表現，人工催熟的策略中使用SPH與雄性激素對於日本鰻生殖成熟發育有正面的幫助。Abstract
In the artificial maturation of Japanese eel by treating salmon pituitary homogenate (SPH) is an effective way to induce oocytes to ovulate and be fertilizable. Furthermore co-treatment of SPH and androgen, this tactic has more obvious advantages, such as more quantity of oocytes and synchronizing development of oocytes etc. Generally, sexual steroids play a part of role in the feedback in brain, hypothalamus and pituitary. In the situation of in vivo experiments, using SPH and androgen for eel maturation could not explain androgen if there are direct affects between liver and ovary. In this study, we use the in vitro way treating SPH and androgen and culturing ovary and liver tissues to measure the expressions of androgen receptor (AR), estrogen receptor (ER), and vitellogenin (Vg). By the expression of ARs, we can judge how the androgen influencing liver or ovary. We take Japanese eels SPH injected one time and changed into sea water in vivo for liver and ovary tissue culture in vitro. In the culturing groups treating androgen, the expressions of ARs, ER and follicle-stimulating hormone receptor (FSHR) increased, but in the groups treating continuous SPH, the expressions of ARs and ER decreased. The androgen can help the expression of ARs, ER, FSHR and Vg increased and the continuous treating SPH decrease these receptors expressions. This study manifest our suppose the androgen have direct and positive effects in eel artificial maturation especially in the early maturation period and not only just play the role of feedback in the brain of female Japanese eels
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
