Comparison of the effects of tualang honey and tibestan in sperm parameters sexual behaviour and hormonal profile among oligospermia males.
Get PDFHoney is used as a medicine from the ancient to modern folks. In Malaysian population, honey was
used as a supplement for men's health since many years although no clear scientific evidence of its benefit. This
study aims to evaluate the effectiveness of Tualang honey on sperm parameters, erectile function, hormonal and
safety profiles.
A randomized control trial was done using Tualang honey (20 gram) and Tribestan (750 mg) over a
period of 12 weeks. Sperm parameters including sperm concentration, motility and morphology were analyzed and
erectile function was assessed using IIEF-5 questionnaire. Hormonal profile of testosterone, FSH and LH were
studied. Safety profile was measured by hematology profile, renal and liver functions besides adverse event
reporting. The volunteers were randomized into two groups and the outcomes were analyzed using SPSS version 18.
A total of 66 participants were involved. A significant increment of mean sperm concentration (p<0.001),
motility (p=0.015) and morphology (p=0.008) were seen in Tualang honey group. In Tribestan group, a significant
I increment of mean sperm concentration (p=0.007) and morphology (p=0.009) were seen. No significant different of
sperm concentration, motility and morphology were seen in between Tualang honey and Tribestan group and similar
results were also seen in erectile function and hormonal profile. All safety profiles were normal and no adverse
event was reported.
Tualang honey effect among oligospermic males was comparable with Tribestan in improving sperm
concentration, motility and morphology. The usage of Tualang honey was also safe with no reported adverse event
Penggunaan Ujian Teras Mikro Sebagai Satu Alternatif Ujian Konkrit Di Situ
Get PDFTerdapat pelbagai jenis ujian konkrit di-situ yang dilaksanakan kini. Antara ujian
yang lazim dilaksanakan ialah ujian kekuatan mampatan teras yang diperolehi daripada
struktur sedia ada. Di dalam ujian ini struktur konkrit yang dibina digerudi untuk
mendapatkan sampel teras dan kemudian diuji bagi mendapatkan satu nilai kekuatan ciri
konkrit. Namun begitu ujian ini merupakan satu ujian yang berisiko tinggi di mana
terdapat beberapa permasalahan yang berlaku terhadap struktur konkrit tersebut. Berikutan
itu, satu ujian baru cuba dihasilkan dengan menggunakan teori yang sama iaitu dengan
melaksanakan kaedah yang dipanggil ujian kekuatan mampatan teras mikro agar dapat
mengatasi permasalahan terhadap ujian yang sedia ada. Maka dengan ini tujuan
penyelidikan ini dilaksanakan adalah untuk mendapatkan satu hubungan antara kekuatan
mampatan teras mikro dengan kekuatan mampatan kiub piawai, untuk digunakan sebagai
rujukan dalam mentafsirkan kekuatan konkrit di tapak binaan. Sebanyak 150 sampel teras
mikro dan 30 kiub piawai (150mm x 150mm x 150mm) mengikut 5 jenis campuran
konkrit digunakan didalam penyelidikan ini. Sampel konkrit telah diuji pada umur 7 dan
28 hari. Hasil penyelidikan telah menunjukkan satu kolerasi yang baik di antara kekuatan
teras mikro dengan kiub piawai. Akhir sekali, segala perubahan atau maklumat di dalam
penyelidikan sampel konkrit turut diambil perhatian sebagai satu keputusan penyelidikan
yang penting berpandukan kepada beberapa rujukan yang dipercayai
Efficacy of Tongkat Ali (Eurycoma longifolia) on erectile function improvement: Systematic review and meta-analysis of randomized controlled trials
Get PDFObjective: To determine the efficacy of Tongkat Ali (Eurycoma longifolia) herbal extract on erectile function improvement. Methods: Comprehensive electronic databases were searched from inception through October 2014. Randomized controlled trials investigating Tongkat Ali compared to placebo were included. Outcome of interest was the improvement of erectile dysfunction. The difference of changes from baseline of the outcome between Tongkat Ali and placebo was pooled using weighted mean difference (WMD). Methodological quality of included studies was assessed using Jadad's quality scale and Cochrane's risk of bias. Results: Of the 342 articles identified, 2 studies involving a total of 139 participants were analyzed. No significance between group difference was found in the mean WMD of the change in the 5- item version of the international index of erectile function (IIEF-5) at week-12 (0.91; 95% CI: -1.50 to 3.33 with I2=89.5%, P-value=0.002) with statistical heterogeneity. Based on the subgroup analysis, significant improved IIEF-5 score of 2.15 (95% CI 1.03-3.27) was found in subjects with lower baseline IIEF-5 score, but this was not seen among those with higher baseline IIEF-5 score. Conclusion: Based on current evidence, the herbal extract of Tongkat Ali may have clinical effect on erectile function. However, more efficacy trials are warranted to further support current evidence
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
