Abstract
AIM: The aim of our study is to evaluate the effect of recombinant-human LH supplementation on ovarian response and pregnancy outcome, during ovarian stimulation, in down-regulated women with baseline low serum LH levels undergoing assisted reproductive technology.
STUDY DESIGN: A prospective randomized study performed with 80 women, with serum LH levels 50.5 IU/l on cycle Day 6 of stimulation. Group-A (40): 14-days after down-regulation with leuprorelin, ovarian stimulation was initiated only with r-FSH 225 IU. Group-B (40): at the same time stimulation was initiated with rFSH 225 IU associated with rLH 75 UI on cycle Day 6 of stimulation.
RESULTS: Serum-E2 levels on the hCG-day administration were significantly reduced in the Group-A. FF-VEGF levels were higher in Group-A. We did not find significant differences in the number of retrieved oocytes. The quality of oocytes proved to be higher and more significant from a statistical point of view in Group-B. The number of embryos obtained and transferred, the pregnancy rate lower in Group-A.
CONCLUSIONS: In our study, it was shown that LH supplementation seems to have a beneficial effect on the maturity and fertilizability of oocyte. Lower FF VEGF levels, found in Group B, could be an indication of a lower apoptosis rate in human cumulus cells after administration of LH. We can affirm that LH-supplementation is beneficial in patients who show asignificant serum LH suppression during the receptorial down-regulatio

Abstract
We report two cases of two women underwent laparoscopic hysterectomy and myomectomy. During surgery, three myomas were identified as completely detached from the uterus, and attached to the bowel. Patients's history revealed a laparoscopic myomectomy. Our first hypothesis therefore was that these were lost myomas of the first surgery. However, only one leyomyoma was removed in both patients. Therefore, we can assume that these myomas were not certainly not lost-myomas and we may conclude that it could be either as residues of previous morcellation or they were pedunculated-myomas that have been spontaneously detached from the uterus and re-implanted onto the bowel
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

We would like to report the history of a fertile 45-year-old woman, referred for persistent metrorrhagia with sonographic evidence of multiple uterine myomas. An endometrial biopsy was performed and a normal endometrium was found from a histological point of view. In due time, she underwent laparoscopic-assisted vaginal hysterectomy with preservation of the ovaries. During surgery, evidence of several intramural fibroids was recorded along with two large pedunculated myomas. After colpotomy, two further myomas of 5 and 3 cm were identified as completely detached from the uterus. They appeared pedunculated (with their vascularization) to the perirectal peritoneum (Fig. 1). Therefore the two fibroids were removed and extracted through the vagina after diathermy coagulation of their vascular stems. From a histological point of view these fibroids were identical to a normal leiomyoma, consisting of fascicles of smooth muscle cells without mitotic figures or nuclear pleomorphism
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
