What we (do not) know about mammal coronavirus and general virus? Using bibliometric information to identify neglected taxonomic groups and potential viral reservoirs of zoonotic importance
Get PDFThe COVID-19 pandemic is currently advancing in the world and has killed more people than other recent coronavirus outbreaks like SARS and MERS together. Coronaviruses known to infect humans were all associated to mammal sources, with different species acting as both natural and/or intermediate hosts of these viruses. Although the zoonotic origin of human coronaviruses is well accepted, a great number of mammal species were not yet investigated as their potential to carry these viruses. This work aimed to provide an overview of the current state of scientific knowledge about what are the mammal groups well known to be associated to coronaviruses and other viruses and what are the most neglected groups in these studies. Here we analyze the production of scientific publications about these and other viruses in association with the 29 taxonomic orders of the Mammalia class. Our results highlighted that most of these taxonomic orders have been little studied or completely unexplored in researches with this focus, with only six orders accumulating more than 99% of the articles on coronaviruses in mammals. Ten mammal groups were not found in any scientific publication in association with coronaviruses, with four of them not found even in works mentioning any type of viruses. These results reinforce the importance of identify all the natural and intermediate hosts for viruses to improve monitoring of potential zoonosis and reduce the chances of new disease outbreaks
Inflammatory parameters in elderly women with and without sarcopenic obesity
Get PDFThe combination of increased fat mass with a decrease in muscle mass and strength in the elderly has been termed sarcopenic obesity (SO). In addition, augmented levels of inflammatory markers have been reported in subjects with SO. Two hundred-sixteen obese elderly women were included in this cross-sectional study. They underwent body composition analysis by DEXA to define the presence of SO. Volunteers were divided into two groups: SO (n= 83; 66.7 ± 5.6 years) and non-SO (n= 133; 67.6 ± 4.9 years) for the comparison of inflammatory cytokines. There were no significant differences between SO and non-SO groups in the blood concentrations of the inflammatory markers analyzed, e.g. interleukin-6 (0.82 ± 0.20 vs 0.83 ± 0.19 pg/ml; p=0.64), C-reactive protein (2.70 ± 1.55 vs 2.82 ± 1.66 pg/ml; p=0.71), tumor necrosis factor alpha (0.71 ± 0.08 vs 0.70 ± 0.08 pg/ml; p=0.42) and interferon-gamma (0.75 ± 0.14 vs 0.74 ± 0.08 pg/ml; p=0.47), respectively. Thus, in the studied population, inflammatory markers are not exacerbated by SO when compared to obesity without sarcopenia

Amplification test and selection of markers analogue to resistance genes in species and commercial varieties of Passiflora spp.
Get PDFBrazil is highlighted as the largest producer and consumer of passion fruit (Passiflora) and holder of representative biodiversity. Studies dedicated to the genetic characterization of the genus in order to understand the existing diversity are important for the advancement of genetic improvement and conservation programs. The aim of this study was to select combinations of RGA (Resistance Genes Analogs) primers for commercial passion fruit species and varieties. To this end, amplification tests were performed on a PCR platform in 17 combinations of RGA primers for eight species and 12 commercial varieties of passion fruit from the Banco Ativo de Germoplasma Flor da Paixão. All combinations of primers have generated amplification products in at least one of the Passiflora samples. The number of combinations that generated amplification products varied from seven to 12 in the species and from three to eight in the varieties. Three to 12 combinations generated amplification products for the samples, emphasizing that the RGA markers were efficient in accessing genomic loci in the species and varieties of passion fruit. The variation of efficient combinations in each of the species and varieties attested to the importance of this research in the preliminary stages of genetic studies as auxiliary tools in conservation and genetic improvement programs. However, this study made it possible to identify combinations of primers to be prioritized in inter and intraspecific genetic characterizations of passion fruit
Teachers’ reflections on mathematics teaching practices in a vulnerable context
Get PDFThe objective of this research is to show the difficulties and the challenges identified by teachers in their mathematics teaching practices. The research is based on the concept of reflection-action, thus a workshop-course centered on collaborative work and on reflections about teaching practices was designed in order to achieve the objective. Ten mathematics teachers the Telebachillerato (Higher Secondary Education Subsystem, Mexico) participated in this research. The results show that teachers have a variety of challenges, but also difficulties, particularly involving getting students to construct knowledge autonomously, as well as teachers selecting and using resources in accordance to the subject matter to be taught. In addition, there is also lack of mathematical and pedagogical knowledge in the participants. Collaborative work is required, leading teachers towards building the necessary knowledge for Higher Secondary Education in order to avoid student obstacles
A modular framework for ontology learning from text in Portuguese
Get PDFResearch on ontology learning has been carried out in many knowledge areas, especially in Artificial Intelligence. Semi-automatic or automatic ontology learning can contribute to the field of knowledge representation. Many semi-automatic approaches to ontology learning from texts have been proposed. Most of these proposals use natural language processing techniques. This paper describes a computational framework construction for semi-automated ontology learning from texts in Portuguese. Axioms are not treated in this paper. The work described here originated from the Philipp Cimiano’s proposal along with text standardization mechanisms, natural language processing, identification of taxonomic relations and techniques for structuring ontologies. In this work, a case study on public security domain was also done, showing the benefits of the developed computational framework. The result of this case study is an ontology for this area
