Effects of dietary high-oleic acid sunflower oil, copper and vitamin E levels on the fatty acid composition and the quality of dry cured Parma ham
No full textThe eects of seven isoenergetic dietary treatments: (1) no sunflower oil, 35 mg/kg Cu, without a-tocopheryl-acetate added; (2) to (7) 6% high oleic acid sunflower oil (HOSO), 35 or 175 mg/kg Cu crossed with a 0, 100 or 200 mg/kg a-tocopherol addition, were tested on quality characteristics of dry cured Parma hams from a total 84 Large White gilts. No statistically significant eect was detected on parameters of early evaluation of seasoning loss of hams. The seasoning loss and intramuscular fat content of seasoned hams averaged 28.1 and 3.3%, respectively, with no eect of the diet composition. The CIE L*a*b* colour values taken on the surface of the lean from Parma ham were not aected by dietary oil inclusion, nor by copper levels and by a-tocopherol addition in the feed mixture, except for the `a' value that increased in HOSO groups (P<0.01) and in groups with a-tocopherol addition (P<0.01). The TBARS values in lean were reduced by the inclusion of HOSO (P<0.05) and a-tocopherol supplementation (P<0.10). Compared to the no oil group, the Parma hams in the HOSO groups showed a higher oleic acid content in the covering fat, but not dierent in neutral and polar fractions from semimenbranosus muscle. The oil inclusion reduced the saturated fatty acid content in subcutaneous fat and neutral lipids fraction from muscle to 30±34% No eect of a-tocopherol and copper levels were observed on fatty acids profiles. From the subjects fed the HOSO diet softer Parma hams were produced than those fed the control diet (w2<0.05), while a-tocopherol and Cu levels did not influence the sensorial evaluation of hams. The inclusion of an oleic acid rich source in heavy pig diet brought about an improved nutritional value, but also the possible need of a prolonged ageing time to achieve an ideal firmness of Parma ham. Dietary a-tocopherol supplementation improved the red colour slightly and the lipid stability in Parma ham, while the supplementation of Cu in the diet had no influence on the tested parameters
Phlegmasia cerulea dolens superimposed on disseminated intravascular coagulation in covid-19
No full textCOVID-19 infection has several cardiovascular implications, and coagulopathy is a common abnormality in these patients, often coupled with elevated plasma fibrinogen and D-dimer levels, contributing to adverse outcomes. Phlegmasia cerulea dolens (PCD) is a rare manifestation of deep vein thrombosis. It is life-threatening and can rapidly lead to venous gangrene of the extremity. Only a few cases of COVID-19 associated with PCD are reported in the literature, despite thromboembolism being the common paradigm between the two diseases. We present the case of a 64-year-old adult with acute severe COVID-19 pneumonia who developed PCD despite constantly elevated activated partial thromboplastin time and international normalized ratio.

Thoracic ultrasound evaluation and B-type natriuretic peptide value in elective cesarean section under spinal anesthesia
No full textPregnancy-induced changes in cardiovascular status make women more susceptible to pulmonary edema. During cesarean section, to counterbalance the effect of hypotension caused by spinal anesthesia, anesthesiologists must choose between two fundamental approaches to maintain the hemodynamic state-intravenous fluids or vasopressors-and this choice will depend upon their particular opinions and experience. We aim to assess for any correlations between thoracic ultrasound A- and B-line artifacts, brain natriuretic peptide (BNP) levels, and the amount of intraoperative fluids administered
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?
No full textIn this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
No full textWe 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
Solitary kidney: the importance of a correct diet and adequate physical activity even in adolescence
No full textIntroduction: The probability of solitary kidney patients developing chronic kidney disease is higher than that of the general pediatric population. Modifiable risk factors such as diet, hydration, physical activity and obesity can influence the prognosis of these patients. The following study aims to quantify adherence to the Mediterranean diet and level of physical activity in solitary kidney children by surveying the parents of these children. In addition, parents were asked other questions about their child’s adherence to a low-sodium diet and physical activity, as well as any concerns they may have about their child’s physical activity. Finally, the prevalence of hypertension was evaluated. Methods: This cross-sectional study includes 47 patients (aged 3-17 years) of the pediatric nephrological ambulatory of Ospedale della Donna e del Bambino of Borgo Trento (Verona), carried out from October 2023 to January 2024. During the visit, we measure the blood pressure of the patient. The parents were subjected to completion of the questionnaires KIDMED: Mediterranean Diet Quality Index in children and adolescents and Godin-Shepard Leisure-Time Physical Activity Questionnaire, and we asked three questions to investigate the parents’ opinions about low sodium diet and physical activity. Conclusion: The nutritional and exercise-related aspects must complement the nephrological one in the follow-up of children affected by solitary kidney. KIDMED and Godin questionnaires can be incorporated into clinical practice to detect individuals at risk early, such as females and subjects with low scores on the KIDMED and GODIN questionnaires. The aim is to refine these patients’ nutritional and physical activity-related follow-up, decreasing the risk of short-and long-term consequences. The Adolescence represents an age historically known for poor compliance with appropriate dietary regimes and adequate levels of physical activity. It could represent a period of life in which the nutritional aspects of the follow-up of solitary kidney should not be underestimate
