Flavoxate: present and future
No full textOBJECTIVE:
This non-systematic review discusses the available evidence on the use of flavoxate in the treatment of overactive bladder (OAB).
METHODS:
Medline was searched for inclusion of relevant studies. No limitations in time were considered.
RESULTS:
Flavoxate hydrochloride is an antispasmodic agent which exerts an inhibition of the phosphodiesterases, a moderate calcium antagonistic activity, and a local anesthetic effect. Results from preclinical and clinical studies show that flavoxate significantly increases bladder volume capacity (BVC), with greater results if compared to other drugs such as emepronium bromide and propantheline. Moreover in clinical trials, both versus placebo or versus active comparators, flavoxate treatment was associated with a significant improvement in different low urinary tract symptoms, such as diurnal and night frequency, urgency and urinary incontinence, suprapubic pain, dysuria, hesitancy and burning. In addition flavoxate was associated with an overall more favourable safety profile than competitors.
CONCLUSIONS:
Several researches and a number of years of clinical practice have proven the efficacy and tolerability of flavoxate administration in the treatment of OAB and associated symptoms. However, new studies are necessary to collect more evidence on the role of this molecule in the treatment of OAB and to further explore its use in other indications such as symptomatic treatment of lower urinary tract infections

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
Histomorphometric analysis of age-related structural changes in human clitoral cavernosal tissue.
No full textI.F. 2.896
PURPOSE: To characterize age-associated histological changes of human clitoral cavernosal tissue and to determine whether age-related histological changes of clitoral cavernosal tissue correlate with vascular disease-related mortality.
MATERIALS AND METHODS: Human clitorises were obtained from 15 fresh cadavers (age: 11 to 90 years) and from 3 patients undergoing clitoral surgery (age: 6 months to 15 years). Cross sections of the clitorises were stained with Masson's trichrome and utilized for computer assisted histomorphometric image analysis to determine the clitoral cavernosal content of smooth muscle and connective tissue.
RESULTS: These studies revealed a strong link between increase in age and decreased clitoral cavernosal smooth muscle fibers. In histomorphometry, the percentage of clitoral cavernosal smooth muscle (mean +/- standard error) in an age group of 6 months to 15 years (n = 4) was 65+/-1.5, in 44 to 54 years (n = 7) was 50+/-1.2, and in 55 to 90 years (n = 7) was 37+/-1.3 (ANOVA, p = 0.0001). In the 18 tissues studied, decrease in the percentage of clitoral cavernosal smooth muscle significantly correlated with increase in age (simple regression, r = 0.61). In the age group of 44 to 90 years, clitoral cavernosal fibrosis was significantly greater in the presence of cardiovascular disease-related mortality compared with those without cardiovascular disease-related mortality.
CONCLUSION: This study shows that aging women undergo histological changes in clitoral cavernosal erectile tissue. Vascular risk factors may adversely affect the structure of clitoral cavernosal tissue. These findings may be of importance in the pathophysiology of age-associated female sexual arousal disorders
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
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
