Massive Pions, Anomalies and Baryons in Holographic QCD
No full textWe consider a holographic model of QCD, obtained by a very simple modification of the original construction, which describes at the same time the pion mass, the QCD anomalies and the baryons as topological solitons. We study in detail its phenomenological implications in both the mesonic and baryonic sectors and compare with the observations. (C) 2011 Elsevier B.V. All rights reserved.LPT
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

Heartworm removal guided by transesophageal echocardiography in a dog with naturally acquired caval syndrome
No full textA 14 mo old shih tzu was referred for dyspnea, hemoptysis, and hematuria. Heartworm disease with caval syndrome was diagnosed by laboratory tests, thoracic radiography, and transthoracic echocardiography. The minimally invasive heartworm removal procedure was performed using flexible alligator forceps guided by transesophageal echocardiography. The procedure was successfully performed removing over 94% of heartworms displayed echocardiographically without any intraoperative complication
Echocardiographic parameters in 50 healthy English bulldogs: preliminary reference intervals
No full textIntroduction/objectives: The objective of the study was to provide echocardiographic reference intervals for English bulldogs (EBs) and to assess if age, sex, body weight (BW), and heart rate have an influence on echocardiographic variables. Animals: We prospectively enrolled client-owned EBs that were considered healthy based on unremarkable history, normal physical examination, six-lead electrocardiography, and transthoracic echocardiography. Materials and methods: Breed-related reference intervals were provided, and associations between age, sex, BW, and heart rate and echocardiographic variables were tested using a multivariate analysis. Allometric scales were generated for echocardiographic variables showing correlation with BW. Moreover, echocardiographic variables obtained in our population of EBs and previous published reference ranges were compared. Results: Echocardiographic reference intervals were generated from 50 healthy adult EBs. As per the multivariate analysis, left atrial diameter (p = 0.015), left ventricular internal end diastolic diameter (p = 0.002), aortic valve annulus (p = 0.032), and pulmonary valve annulus (p = 0.017) resulted influenced by BW, and reference intervals were generated using allometric scales. Our study suggests that EBs tend to have a smaller aortic root and sphericity index than other breeds. In addition, EBs seem to have smaller indexed left ventricular volumes and higher left ventricular ejection fraction than boxers and Doberman. Conclusion: Preliminary reference intervals in the EBs are reported, which might be helpful for accurate echocardiographic interpretation and screening purposes in this breed
