Human osteoclasts express oxytocin receptor.
Increasing evidences demonstrated many new targets for the hypothalamic hormone oxytocin, as the regulation of food balance and in some cases of leptin secretion. Considering that leptin is a potent inhibitor of bone formation and that oxytocin receptors (OTR) were detected in normal human osteoblasts, we investigated if OTR was expressed by human osteoclasts (hOCs) and the effect of the hormone on these cells. Here, we demonstrate by immunofluorescence and by Western blot analysis the expression of OTR by fully differentiated hOCs and by their precursors (pOCs). We also show that the receptor is functional, as OT treatment induces an increase of [Ca(2+)](i), and that the hormone may affect osteoclastogenesis, since it increases the number of pre-osteoclasts
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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

Dental Pulp Stem Cells Isolation and Osteogenic Differentiation: A Good Promise for Tissue EngineeringStem Cells and Tissue Repair
Adult stem cells therapy can be an efficacious treatment for many diseases and disabilities. New sources of stem cells in adult organisms are continuously emerging. Dental tissues that are easily accessible by a tooth extraction have been identified as a source of postnatal mesenchymal stem cells capable of self-renewal and multipotency. Here, we describe accurately the technical procedure to isolate mesenchymal stem cells from dental pulp (DPSCs), characterize their immunophenotype, and assay their osteogenic capacity
