Correlazione tra conformazione del piede ed effusione dell’articolazione interfalangea distale agli arti anteriori in giovani cavalli all’inizio della preparazione atletica

Latero-medial radiographic parameters related to foot conformation were. measured and statistically compared between 25 horses with and 25 horses without distal. interphalangeal joint effusion. A strong positive correlation with long toe-low heels. conformation was found, indicating bigger workload at the distal interphalangeal joint, which. could be reduced by correct trimming of the hoof.\\\"\"

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
Radiographic evaluations of distal navicular border fragments and forefeet conformation in the horse
No full textRadiographic examination has good sensitivity in revealing fragments located at the distal border of the
navicular bone (DSBF) in the dorsoproximal-palmarodistal oblique (DPr-PaDiO) view with a proximo-distal
angle between 55° and 65° (1). DSBF is a common finding in lame horses as well as in radiographic
screenings (2).
Aim of the study was to evaluate the correlation between presence of DSBF and navicular and forefeet
conformation.
The radiographs of 120 horses (Italian Saddlebred and Angloariabian, aged 3-15 years), obtained during
pre-purchase or for diagnostic purposes, were used. Feet were classified in 3 groups: 1. lame feet with
DSBF, 2. lameness-free feet with DSBF, 3. feet from sound horses without DSBF. Location of the lameness
at the foot was confirmed by diagnostic anesthesia in lame horses.
The averages of 3 consecutive measurements of 3 ratios and 1 angle were statistically compared among the
3 groups: 1. distal navicular border length / navicular maximal width ratio (Y/Z), 2. height of sole at the toe /
height of the heels ratio (E/D), 3. length of the toe / length of the foot ratio (C/B), 4. angle of the dorsal
hoof wall to the ground (F).
In feet with DSBF, Y/Z, E/D and C/B ratios were higher if compared with feet without fragment (P<0.05). In
feet with fragment, feet without lameness showed higher E/D ratio than feet with lameness (P<0.05).
Although the difference was not statistically significant, Y/Z and C/B ratios were also higher in lame feet if
compared with non lame feet.
Even if not statistically significant, F angle was smaller in feet with both fragment and lameness and in feet
without fragment if compared with feet with fragment without lameness.
DSBF seem to be more present in navicular bones with more “rectangular” rather “trapezoidal” shape in
the DPr-PaDiO 60° oblique view (high Y/Z ratio) and in feet with long toe-low heel conformation (high E/D
and C/B ratios). This correlation between conformation of the foot, navicular shape and presence of DSBF
suggests an important role of mechanical forces in the occurrence of DSBF in horses's foot and highlight the
importance of early foot trimming and managment.

Differentiation of glycans in equine guttural pouches.
No full textThe aim of this study was to investigate the carbohydrate composition of mucosubstances in the equine guttural pouches using conventional
histochemical tests in conjunction with glycolytic digestion to degrade different classes of glycosoaminoglycans. In the goblet
cells, the mucopolysaccharides contained chondroitin sulfate B, heparin, heparan sulfate and sialic acid residues. The acinar cells also
expressed these substances (except for heparin), whereas the ductal cells produced chondroitin sulfate B and sialic acid. Neutral sugars
were also found in each cell type. The diversity of the glycocomponents found in the auditory tube suggests that they may have important
functional roles. Indeed, the glycosoaminoglycans provide a hydrophilic environment that prevents dehydration and desiccation of the
guttural membranes during air passage. Additionally, these glycomolecules may be involved in the pathogenesis of some bacterial disease
in horses, such as equine strangles
