An experimental study of a cyanoacrylate biological adhesive in view of its use in the fixation of various fractures of the fingers.
No full textFollowing certain interesting results reported in publications by researchers from the nineteen-sixties up to the present time, we decided to experiment a particular adhesive with high adhesive properties: this is composed of monomers of alpha-cyanoacrylate éthyl-2-alpha-cyanoacrylate. For this end, experiments were performed on 15 adult chickens, aged around 4 months, weighing 2 kg, divided into 5 groups of 3 chickens each. In each chicken, a rectangular bone fragment from the proximal-middle third of the tibia was prepared, completely separated, and then subsequently re-positioned and fixed with the adhesive plus collagen. At pre-established intervals (7, 14, 21, 30 and 60 days), each group of chickens was examined by x-rays and then killed, so that the particular anatomical part under examination could be studied both microscopically and macroscopically. The aim of these experiments was to evaluate the ability of cyanoacrylate adhesive to ensure setting of small bone-fragments that would otherwise be unstable. The results obtained showed the following: good stability of the bone fragment; good bone consolidation; absence of foreign body reactions. The positive nature of these results leads us to propose the use of this adhesive in hand surgery. Nevertheless, duty requires that further experiments be performed in order to acquire even greater guarantees for the positive results obtained
EXPERIENCE OF MULTIDISCIPLINARY TEAM FOR COMPLEX HAND FUNCTION PROBLEMS AT THE RHEUMATOLOGY OUTPATIENT CLINIC OF MODENA
No full textOrthopedic surgery (OS) is an integral part of the total management programme for patients with rheumatic disease (RD). Indication for synovectomies as well reconstructive surgery in RD should be based on a joint decision between the patient, the rheumatologist, the orthopaedic surgeon as well as other health professional. The proposed functional activities of the patients and their own personal goals should be taken into account. Consequently, the package of care should be individual and tailored to the persons identified needs.In 2006 in Academic Hospital of Modena, Italy, at the Rheumatology outpatient clinic a multidisciplinary team has been performed consisting of rheumatologists, hand surgeon, physiatrist, and hand physiotherapist, occupational therapist). Rheumatologists normally are responsible for referring the patients on to others specialists. The team works together to evaluate patients affected by chronic inflammatory diseases (rheumatoid arthritis - RA, spondyloarthropaties - Spa, microcristalline arthropathy) or connective tissue diseases with complex hand function problems.The discussion during the visit and the execution of the various tests have enabled patients to understand functional changes that the disease has caused and has made them more available to use splints or to undergo surgery.At the end of the diagnostic and functional study 19 patients were sent to the surgery (9 synovectomies, 10 reconstructive surgeries) while the others received physiotherapy/rehabilitation appropriate to their needsConclusion: These aspects support a team approach in the planning and performance procedures in patient with rheumatic diseases; ideally, orthopaedic surgeon, physiatrist, and rheumatologist as well as the multidisciplinary team should work together in a functional musculoskeletal unit with a multidisciplinary approach.Patients showed to appreciate this approach

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
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
