The influence of intra-articular hyaluronic acid on PGE2 and cAMP of synovial fluid
No full textProstaglandin (PG)E2, cyclic adenosine monophosphate (cAMP), white blood cells (WBC), total protein (TP), total complement activity (CH50) and beta-2-microglobulin (beta-2-m) were measured at baseline and after eight days in the synovial fluid (SF) of 16 patients affected with knee-joint effusion due to various arthropathies. The volume of SF was also calculated. Eight patients--4 with rheumatoid arthritis (RA), 2 with recurrent monoarthritis (RM) and 2 with osteoarthritis (OA) were randomly allocated to the treatment with intra-articular injection of Hyalgan (HA, Na-hyaluronate, 20 mg/2 ml), while eight patients having similar arthropathies--4 RA, 2 RM and 2 OA--were not treated (control group). In the patients treated with HA a significant reduction of SF volume (from 28.5 +/- 5.1 ml to 20.5 +/- 4.0 ml; p less than 0.02) and PGE2 (from 96.1 +/- 22.7 pg/ml to 66.2 +/- 14.5 pg/ml; p less than 0.05) was found, whereas cAMP concentration was significantly increased (from 4.5 +/- 0.7 pmol/ml to 7.2 +/- 1.2 pmol/ml; p less than 0.05). No significant variations were observed in the control group. Moreover, no differences in WBC count, TP and beta-2-m and CH50 were found in either group. These data could suggest an anti-inflammatory effect of HA that appears to be mediated by PG-inhibition as well as cAMP stimulation

Anti-thyroid microsomal antibody in synovial fluid as a revealing feature of seronegative autoimmune thyroiditis
No full textVariations on the Author
No full text“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

Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
