Calcinosis circumscripta associated with polydioxanone suture in two young dogs
No full textCalcinosis circumscripta associated with polydioxanone suture material was diagnosed in two young dogs. In each case, the owner noticed a firm mass at the site of a previous surgical incision. Mineralization of soft tissues was visible radiographically. At excision, multiple chalky white nodular masses within the subcutis extended in a linear pattern the length of the sutured incision, but not beyond it. Polydioxanone suture was identified within the centre of the nodules, which were identified histologically as calcinosis circumscripta..RE: 14 ref.; SC: VE; CA; 0I; ZA; 7VSource type: Electronic(1) http://upei-resolver.asin-risa.ca?sid=SP:CABI&id=pmid:&id=&issn=0161-3499&isbn=&volume=18&issue=3&spage=216&pages=216-220&date=1989&title=Veterinary%20Surgery&atitle=Calcinosis%20circumscripta%20associated%20with%20polydioxanone%20suture%20in%20two%20young%20dogs.&aulast=Kirby&pid=%3Cauthor%3EKirby%2c%20B%20M%3bKnoll%2c%20J%20S%3bManley%2c%20P%20A%3bMiller%2c%20L%20M%3C%2Fauthor%3E%3CAN%3E19892295704%3C%2FAN%3E%3CDT%3EJournal%20article%3C%2FDT%3
Efficacy of polycaprolactone in maintenance of bone defects in ulnar ostectomies
No full textPolycaprolactone (PCL), a synthetic polyester, was investigated as an interpositional material to delay bone healing following partial ulnar ostectomies in dogs. Bone healing did not occur in 6 of 10 ostectomy sites 8 to 24 weeks following surgery in which a PCL cap was placed over the proximal cut end of the ulna, or in four of six ostectomy sites filled with melted PCL that hardened into a plug. Bone healing occurred in ulnectomy sites in which technical problems in positioning and stabilizing the polymer implants occurred. The PCL was well tolerated by the dogs and was an effective mechanical barrier to tissue bridging when adequately stabilized..RE: 15 ref.; SC: ZA; CA; VE; 0V; 7V; 0ISource type: Electronic(1) http://upei-resolver.asin-risa.ca?sid=SP:CABI&id=pmid:&id=&issn=0161-3499&isbn=&volume=15&issue=5&spage=369&pages=369-374&date=1986&title=Veterinary%20Surgery&atitle=Efficacy%20of%20polycaprolactone%20in%20maintenance%20of%20bone%20defects%20in%20ulnar%20ostectomies.&aulast=Runnels&pid=%3Cauthor%3ERunnels%2c%20C%20M%3bRunyon%2c%20C%20L%3bMerkley%2c%20D%20F%3C%2Fauthor%3E%3CAN%3E19872289438%3C%2FAN%3E%3CDT%3EJournal%20article%3C%2FDT%3
Hemodynamic effects of atropine and glycopyrrolate in isoflurane-xylazine-anesthetized dogs
No full textThe purpose of this study was to evaluate and compare the haemodynamic changes caused by the administration of i.v. atropine or glycopyrrolate after i.v. xylazine in isoflurane-anaesthetized dogs. Six healthy Beagles (8.2 to 10.7 kg) were used in 2 trials separated by 7 days. Anaesthesia was induced and maintained with isoflurane in 100% oxygen with controlled ventilation. Once constant end-tidal isoflurane (1.8%) and arterial partial pressure of carbon dioxide (35 to 45 mm Hg) values were reached, baseline data were recorded and xylazine (0.5 mg/kg, i.v.) was given. In trial 1 atropine (0.1 mg/kg, i.v.) was given 5 min after xylazine, and in trial 2 glycopyrrolate (0.025, mg/kg, i.v.), was given 5 min after xylazine. Haemodynamic variables were recorded 3 min after xylazine and 3 min after anticholinergic administration. In trial 2, bilateral vagotomies were performed 10 min after glycopyrrolate, and haemodynamic variables were recorded 3 min later. Heart rate, cardiac index, and stroke index decreased; arterial pressure and systemic vascular resistance increased after xylazine. Heart rate, cardiac index, and rate pressure product increased after anticholinergic administration. Significant differences between atropine and glycopyrrolate were not observed in any of the haemodynamic parameters. Similarly, significant differences between glycopyrrolate and bilateral vagotomy were not observed. The authors conclude that i.v. atropine and glycopyrrolate have equivalent haemodynamic actions during the increased pressure phase after i.v. xylazine in isoflurane-anaesthetized dogs; that i.v. atropine and glycopyrrolate produce comparable increases in heart rate and that both may increase the risk of myocardial hypoxia associated with an increase in rate pressure product; and that vagal blockade produced by high-dose glycopyrrolate (0.025 mg/kg, i.v.) is similar to that produced by bilateral vagotomy..RE: 20 ref.; RN: 51-55-8; 55-48-1; 26675-46-7; 7361-61-7; SC: CA; ZA; VE; 0I; 0V; 6VSource type: Electronic(1) http://upei-resolver.asin-risa.ca?sid=SP:CABI&id=pmid:&id=&issn=0161-3499&isbn=&volume=22&issue=2&spage=163&pages=163-169&date=1993&title=Veterinary%20Surgery&atitle=Hemodynamic%20effects%20of%20atropine%20and%20glycopyrrolate%20in%20isoflurane-xylazine-anesthetized%20dogs.&aulast=Lemke&pid=%3Cauthor%3ELemke%2c%20K%20A%3bTranquilli%2c%20W%20J%3bThurmon%2c%20J%20C%3bBenson%2c%20G%20J%3bOlson%2c%20W%20A%3C%2Fauthor%3E%3CAN%3E19932283834%3C%2FAN%3E%3CDT%3EJournal%20article%3C%2FDT%3

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
Influence of cholinergic blockade on the development of epinephrine-induced ventricular arrhythmias in halothane- and isoflurane-anesthetized dogs
No full textThe arrhythmogenic effects of anaesthetic drugs were assessed using the arrhythmogenic dose of epinephrine (ADE) model. The purpose of this study was to determine the influence of cholinergic blockade (CB) produced by glycopyrrolate (G) on ADE in 1.5 minimum alveolar concentration (MAC) halothane (H)- and isoflurane (I)-anaesthetized dogs. Eight dogs (weighing between 12.5 and 21.5 kg) were randomly assigned to 4 treatment groups (H, HG, I and IG), each treatment replicated 3 times. Anaesthesia was induced and maintained with H (1.31%, end-tidal [ET]) or I (1.95%, ET) in oxygen. Ventilation was controlled (carbon dioxide [PCO2] 35 to 40 mmHg, ET). G was administered 10 minutes before ADE determination at a dose of 22 micro g/kg (11 micro g/kg, i.v., and 11 micro g/kg, i.m.). The ADE was determined by IV infusion of epinephrine at sequentially increasing rates of 1.0, 2.5 and 5.0 micro g/kg/min; and defined as the total dose of epinephrine producing at least 4 ectopic ventricular contractions (EVCs) within 15 seconds during a 3-minute infusion and up to 1 minute after the end of the infusion. Total dose was calculated as the product of infusion rate and time to arrhythmia. Values are reported as means +or- standard error. The ADE ( micro g/kg) for H, HG, I and IG were 1.53 +or- 0.08, 3.37 +or- 0.46, 1.61 +or- 0.21 and >15.00, respectively. Heart rates (HRs) (beats/min) and systolic pressures (mmHg) at the time of arrhythmia formation for H, HG, I and IG were (60.3 +or- 4.0 and 142 +or- 7.6), (214.0 +or- 13.1 and 239.2 +or- 7.1), (62.9 +or- 4.5 and 151.9 +or- 6.3) and (226.3 +or- 6.1 and 323.5 +or- 3.4), respectively. The H and I ADE were not different. The GH ADE was significantly less than the IG ADE. The H and I ADE were significantly less than the HG and IG ADE. It is concluded that epinephrine infusion in halothane- and isoflurane-anaesthetized dogs: (1) two distinct mechanisms are responsible for the development of arrhythmias, (2) CB produced by G significantly increases ADE but is associated with higher rate pressure products (RPP) and myocardial work, and (3) ADE methodology could be improved by determining ADE with and without CB..RE: 18 ref.; RN: 51-43-4; 26675-46-7; 151-67-7; SC: CA; VE; 0I; ZA; EC; 0V; 6VSource type: Electronic(1) http://upei-resolver.asin-risa.ca?sid=SP:CABI&id=pmid:&id=&issn=0161-3499&isbn=&volume=23&issue=1&spage=61&pages=61-66&date=1994&title=Veterinary%20Surgery&atitle=Influence%20of%20cholinergic%20blockade%20on%20the%20development%20of%20epinephrine-induced%20ventricular%20arrhythmias%20in%20halothane-%20and%20isoflurane-anesthetized%20dogs.&aulast=Lemke&pid=%3Cauthor%3ELemke%2c%20K%20A%3bTranquilli%2c%20W%20J%3bThurmon%2c%20J%20C%3bBenson%2c%20G%20J%3bOlson%2c%20W%20A%3C%2Fauthor%3E%3CAN%3E19942206089%3C%2FAN%3E%3CDT%3EJournal%20article%3C%2FDT%3
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
