Acute motor neuropathy after intrathecal treatment with methotrexate: A case report
No full textIntrathecal therapy with methotrexate and cytosine-arabinoside is a therapeutic strategy for maintaining remission in patients with acute lymphoblastic leukemia, that is associated with neurological side effects are described. We report a 4-year-old girl who became tetraplegic after the last dose of intrathecal therapy. Cerebrospinal fluid showed elevated protein level and nerve conduction study revealed a motor neuronopathy. Spine magnetic resonance imaging revealed gadolinium enhancement of the anterior roots of the cauda equina. We describe a myelopathy confined to the anterior horns and anterior spinal nerve roots without sensory involvement caused by intrathecal methotrexate. The pathogenesis of this selective involvement remains uncertain. © 2007 IOS Press. All rights reserved
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
Scientific Production in Dentistry: The National Panorama through a Bibliometric Study of Italian Academies
Full text linkBackground. The academic scientific research in the field of dentistry has rapidly increased in the last 20 years under the pressure of the multidisciplinary technological advancements and the growing demand for new predictable and cost-effective techniques and materials. The aim of the present investigation was to analyze the academic scientific production conducted by Italian Academies and Dental Schools. Methods. The list of MED/28 academic researchers, associate and full professors, and academic affiliations was collected from the national database of CINECA to evaluate the scientific output of the Italian Universities. The complete list of scientific contributions and the bibliometric parameters were recorded in the Scopus database. Results. The scientific production of 37 Italian Universities, 416 researchers, and 23689 papers was evaluated. The measurement of total academic papers, citations, h-index, and relative citation ratio (RCR) was calculated. The study data showed an increase of the academic scientific production over the last 5 years. Conclusions. The results presented show how scientific research is increasingly pursued by dental clinicians
Looking at flavonoid biodiversity in horticultural crops: A colored mine with nutritional benefits
Full text linkFlavonoids represent a wide group of plant secondary metabolites implicated in many physiological roles, from the attraction of pollinators to the protection against biotic or abiotic stresses. Flavonoids are synthetized in a number of horticultural crops that are important components of our daily diet. In the last decades, the consumption of vegetables rich in antioxidants has been strongly promoted from the perspective of prevention/protection against chronic diseases. Therefore, due to their nutritional importance, several attempts have been made to enhance flavonoid levels in species of agronomic interest. In this review, we focus on the flavonoid biodiversity among the major horticultural species, which is responsible of differences among closely related species and influences the qualitative/quantitative composition. We also review the role of flavonoids in the nutritional quality of plant products, contributing to their organoleptic and nutritional properties, and the main strategies of biofortification to increase their content

No full textThe impact of COVID-19 on the scientific production spread: A five-month bibliometric report of the worldwide research community
Full text linkIntroduction: The recent COVID-19 pandemic has gained recently a deep increasing of research interest in all fields of the human knowledge due to prevention of the Sars-Cov-2 infection and disease treatment The present investigation evaluated the topic publications and the citation network analysis during the early phases of COVID-19 pandemic spread.
Methods: the Boolean search was performed according to the Pubmed Mesh terms by by Scopus Elsevier database. The papers, co-authors, number of citations obtained and scientific journals were recorded.
Results: a total of 164 scientific journals were assessed in the present research with a mean impact factor value of 4.612±8.705 (range: 70.67-0; median: 2,687, Q1: 0,701; Q3: 4,928).
Conclusions: The studies selected showed The bibliometric research showed an early representation of the research orientation of the research activity about COVID 19. The most represented scientific fields concerned with healthcare and medicine, while for the social and economic fields are gaining interests due to the pandemic spread
