The influence of tocotrienol on the development of preimplantation embryos and pregnancy outcome in corticosterone-treated mice / Nasibah Azme
No full textTocotrienol (TCT), a component of vitamin E is a powerful antioxidant whereas corticosterone (CORT), a known prooxidant has been shown to impair the development of embryo and pregnancy outcome. This study aims to determine the effect of TCT supplementation on the quality and in vitro development of embryos and the pregnancy outcome in CORT-treated mice. In embryonic experiment, 5- to 6 weeks old female mice were divided into four groups of eight animals. They received CORT (10 mg/kg) intraperitoneal (ip) concurrently with TCT at the dose of 30, 60 and 90 mg/kg orally and the control group had 0.1 ml com oil (ip) and orally for seven consecutive days. On Day 7, after superovulation and mating, animals were euthanized and embryos were flushed out from the fallopian tubes. The morphology and in vitro development of embryos were recorded. In pregnancy outcome experiment, 7- to 8 weeks old female mice were divided into similar groups and treatment for the first seven days of pregnancy were conducted as above with using TCT at 60, 90 and 120 mg/kg. On Day 7 of pregnancy, laparotomy was done to determine the number of implantation sites; to observe any resorption signs while litter sizes were measured at birth. It was found that TCT (90 mg/kg) improved the quality of embryo whereas TCT (60 mg/kg) increased the number of embryos that reached hatched blastocyst stage in CORT-treated groups. In addition to that, TCT (60 mg/kg) increased the implantation sites, whereas TCT (120 mg/kg) decreased the resorption percentage and increased the level of progesterone hormone towards control in CORT-treated pregnant mice. Tocotrienol supplementation in our study is able to reverse the CORT-induced adverse impact on all reproductive outcomes as mentioned above. The effect of TCT alludes further exploration to ascertain their mechanism
Ice breaker game during the first F2F problem-based learning classroom: enhancing student interaction and teamwork / Nasibah Azme
Full text linkProblem-based learning (PBL) is a teaching method that focusses on student-centred learning (Ali, 2019). The educational goal of PBL is to enable students to develop their analytical, reasoning, problem-solving, and self-learning skills. The PBL in the medical faculty has the potential to help structure basic scientific knowledge in a clinical context and promote generic skills. An effective PBL requires student engagement and interest (Song et al., 2022). A crucial element of PBL is teamwork. Students must work in teams and collaborate to solve the problem and apply knowledge (Fontejin & Dolman, 2019). Due to the Covid-19 pandemic, the Faculty of Medicine at UiTM had implemented hybrid learning for all classes, including PBL. Hybrid learning means students need to join their classes virtually from home at the beginning of the semester, and attend these class in person in the mid- semester
Simulations of OSPEs using socrative teacher-paced setting during the COVID-19 Pandemic / Nasibah Azme
Full text linkDue to the COVID-19 outbreak, there has been a dramatic change in education, specifically seen in the distinctive rise of the implementation of online distance learning by academic institutions. In the same way, all medical curricula have been transformed into online settings, including examinations such as the Objective Structured Practical Examinations (OSPEs), which evaluate preclinical students’ practical and laboratory skills. The conventional protocol involves students being assessed at individual OSPE stations whereby a specific duration is allocated for each station. However, under the conditions mediated by the COVID-19 pandemic, there have been unprecedented challenges in generating electronic OSPEs as well as difficulties medical students face as they are undergoing online OSPEs for the first time. As it is important to ensure students are prepared for their semester exam during this pandemic, medical educators have obliged to embark on to various online platforms to generate OSPEs questions. Hence, this paper aims to provide a platform namely in the form of Socrative for the purpose of designing OSPEs questions. This platform enables educators to simulate real OSPEs by controlling the flow of questions according to set durations through the use of the teacher-paced setting. A demonstration of this process was first shown to a small group of 23 medical students, after which the Socrative teacher-paced setting was used twice. At the end of the simulation, several close-ended and open-ended questions were provided to collect respondents’ feedback. The results showed that all the respondents agreed with the belief that Socrative teacher-paced setting mimics real OSPEs. Hence, this approach permits medical students to perform multiple practice attempts prior to the semester examination. Through this initiative, it is hoped that their learning and examination performance would be enhanced
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
