IDENTIFICAÇÃO DAS ÁREAS DE VULNERABILIDADE AMBIENTAL NA CIDADE DE PONTA PORÃ – MS

A caracterização da vulnerabilidade dentro destas áreas é um importante processo para a conservação e gestão adequada dos recursos naturais. O presente trabalho teve o propósito de identificar as áreas de vulnerabilidade ambiental na área urbana de Ponta Porã - MS, utilizando recursos gratuitos de sensoriamento remoto e geoprocessamento disponibilizados pelo INPE (Instituto Nacional de Pesquisas Espaciais). Para desenvolvimento desse trabalho foram utilizadas imagens orbitais do município de Ponta Porã – MS, por meio das bandas 3 e 4, geradas pelo sensor Thematic Mapper, TM, do satélite Landsat 5. O processamento e integração dos dados de sensoriamento remoto foram realizados no software Spring 5.0.6 (Sistema para Processamento de Informações Georreferenciadas) desenvolvido pelo INPE, no qual foi construído um banco de dados geográficos tendo como parâmetros cartográficos, o sistema de projeção UTM (Universal Transversa de Mercator) e o Datum WGS 84. Percebe-se que as áreas de maior vulnerabilidade ambiental estão localizadas principalmente em regiões de grande declividade, associadas, a solo exposto de natureza compactada e com baixo índice de vegetação. Estas áreas localizam-se em fundos de vale que tiveram sua cobertura vegetal extraída, sendo susceptíveis a movimentos de massa e enxurradas. Tais locais, tornam-se inapropriadas para expansão urbana e prioritárias para conservação ambiental. Por outro lado, o produto gerado se torna importante na identificação de áreas potencialmente estáveis, que se tornam apropriadas para fins de planejamento e ordenamento territorial, sobretudo, na instalação de futuros empreendimentos

Perfil dos egressos do curso de Administração EaD/UFSC/UAB e a consonância com a política educacional de EaD

Esta pesquisa objetivou analisar o perfil do egresso do curso de administração de Educação a Distância da Universidade Federal de Santa Catarina ofertado por meio do Sistema Universidade Aberta. O estudo foi pautado na visão de Sechi (2010) quanto à visão de política pública. Para tanto, houve uma descrição da política pública operacionalizada através do sistema UAB de acordo com levantamento da legislação brasileira. Verificou-se o número de egressos por polo para o curso em análise, e, houve uma conseguinte análise das características de sexo, idade, cidade de residência, IDH do município do polo e por fim a procedência escolar do aluno: se ele concluiu o ensino médio em instituição pública ou privada. A abordagem do estudo foi predominantemente quantitativa, complementada por análise qualitativa tendo em vista o preconizado na política pública. Entre os resultados, cita-se que o perfil do egresso está em consonância com o perfil nacional, sendo na maioria alunas com idade superior a 26 anos. Do total de egressos 83% são oriundos de instituições públicas. A concentração da residência dos alunos está em sua maioria a um raio de 50km em relação ao polo. A cidade que abriga o polo e a circunvizinhança possuem IDH médio. Apesar da aparente consonância muito há que ser feito no país a fim de reduzir as desigualdades e promover uma redemocratização efetiva do acesso ao ensino superior.This study aimed to analyze the profile of management´s graduates of the course in Distance Education of Universidade Federal de Santa Catarina offered by Universidade Aberta do Brasil to verify the compliance with the Distance Education policy in Brazil. The studied was carried through the lens of Sechi (2010) studies about policy. Therefore, there was a description of the the public policy implemented through the UAB system according to the Brazilian legislation. It was also verified the number of graduates per pole, and accordingly there was a analysis of the characteristics of gender, age, city of residence, HDI from the municipality in which the polo was based and finally the student provenance school: if he finished high school in public or private institution. The approach for this study was predominantly quantitative, supplemented by qualitative analysis in accordance with the policy content. Among the results, it is cited that the profile of graduates is in line with the national profile, with most students over the age of 26 years and female gender. Of the total 83% of graduates were provenient from public institutions. The residence of the students is concentrated mostly on a radius of 50km over the pole. The city which host the polo and its surrounding region have medium HDI. Despite the apparent line there is much to be done in the country in order to reduce inequalities and promote an effective democratization of access to a higher education.Universidade Aberta; Pavilhão do Conhecimento; LEA

Advances in extraction methods to recover added-value compounds from seaweeds: sustainability and functionality

Seaweeds are a renewable natural source of valuable macro and micronutrients that have attracted the attention of the scientists in the last years. Their medicinal properties were already recognized in the ancient traditional Chinese medicine, but only recently there has been a considerable increase in the study of these organisms in attempts to demonstrate their health benefits. The extraction process and conditions to be used for the obtention of value-added compounds from seaweeds depends mainly on the desired final product. Thermochemical conversion of seaweeds, using high temperatures and solvents (including water), to obtain high-value products with more potential applications continues to be an industrial practice, frequently with adverse impact on the environment and productsâ functionality. However more recently, alternative methods and approaches have been suggested, searching not only to improve the process performance, but also to be less harmful for the environment. A biorefinery approach display a valuable idea of solving economic and environmental drawbacks, enabling less residues production close to the much recommended zero waste system. The aim of this work is to report about the new developed methods of seaweeds extractions and the potential application of the components extracted.This work was funded by the Portuguese Foundation for Science and Technology (FCT) un der the scope of the strategic funding of UIDB/04469/2020 unit and BioTecNorte operation (NORTE-01-0145-FEDER-000004) funded by the European Regional Development Fund under the scope of Norte2020—Programa Operacional Regional do Norte.

inTB - a data integration platform for molecular and clinical epidemiological analysis of tuberculosis

This deposit is composed by the main article plus the supplementary materials of the publication.Tuberculosis is currently the second highest cause of death from infectious diseases worldwide. The emergence of multi and extensive drug resistance is threatening to make tuberculosis incurable. There is growing evidence that the genetic diversity of Mycobacterium tuberculosis may have important clinical consequences. Therefore, combining genetic, clinical and socio-demographic data is critical to understand the epidemiology of this infectious disease, and how virulence and other phenotypic traits evolve over time. This requires dedicated bioinformatics platforms, capable of integrating and enabling analyses of this heterogeneous data.Instituto Gulbenkian de Ciência, Programa Nacional de Luta contra a Tuberculose, Instituto Nacional de Saúde Ricardo Jorge, Administração Regional de Saúde de Lisboa e Vale do Tejo

Prognostic Factors and Life Expectancy in Canine Leishmaniosis

Canine leishmaniosis (CanL) is a chronic and potentially fatal disease. The prognosis of CanL depends on the severity of the clinical signs and clinicopathological abnormalities presented by the dog at the time of diagnosis. This study aims to estimate the survival time of dogs with CanL, determining the prognostic value of different clinical and clinicopathological parameters. Medical records of 99 dogs diagnosed with CanL in five veterinary centers of the Alentejo region (Portugal) were examined retrospectively. The majority of dogs presented hyperproteinemia, moderate normocytic normochromic anemia, normal blood urea and creatinine levels and were classified as stage 1 according to the International Interest Society (IRIS) guidelines at the time of diagnosis. The severity of anemia, presence of concomitant infectious diseases at the time of diagnosis and the anti-Leishmania therapy were correlated with the survival time. The influence of renal dysfunction was evaluated by Receiver Operating Characteristic (ROC) curve and survival analysis. Survival analysis demonstrated that patients classified as IRIS 1 at the time of diagnosis survived more than four years, in contrast with dogs classified as IRIS 2 that survived around two and half years and dogs classified as IRIS 3–4 that survived around one month. IRIS stage deteriorated during the course of CanL in one third of the dogs and was the principal cause of death or euthanasia in a high proportion of animals. In some cases, dogs did not receive anti-Leishmania treatment or abandoned the veterinary follow-ups, which may have considerable repercussions for animal wellbeing and public health. This study reinforces the value of blood urea and creatinine levels as prognostic factors in CanL.info:eu-repo/semantics/publishedVersio

Hemoperitoneum in a Cow with Lumbar Muscle Hemangiosarcoma

Background: Hemangiosarcoma is a malignant neoplasm of endothelial cells with an infiltrative growth pattern. Hemangiosarcomas are frequently reported in canines and rare in felines, sheep, goats, swine, horses and cattle. Few cases of hemangiosarcoma were reported in cattle. In the present report, we describe the clinicopathological findings of a bovine muscle hemangiosarcoma.Case: A 6-year-old, Girolando cow from the Dairy Cattle Sector of the Federal Rural University of Rio de Janeiro (UFRRJ), Seropédica, presented sternal decubitus. Clinical signs were markedly pale mucous membranes, moderate dehydration, respiratory distress, and increased heart rate. The hematological examination revealed intense regenerative anemia. Due to the worsening of the clinical condition, the cow was submitted to euthanasia. The necropsy and collection of various fragments of organs were performed, which were sent to the “Setor de Anatomia Patológica” (SAP-UFRRJ). Tissues were fixed in 10 % buffered formalin, routinely processed for histology and stained with Hematoxylin and Eosin (HE). The external mucous membranes were markedly pale. Multifocal areas of 1.5 x 1.0 cm, irregular and dark red were observed dissecting the quadratus lumborum muscle (hemangiosarcoma) fibers. These neoplasms were associated with an extensive cruoric clot adhered to the muscle fibers. The extensive, red, friable mass measured approximately 76 x 55 x 20 cm on the serous surfaces of the organs of the peritoneal cavity (hemoperitoneum). The spleen was moderately reduced. The bone marrow was markedly pale. Histologically, it was observed that there was an extensive proliferation of endothelial cells in the quadratus lumbar muscle mass dissecting the epimysium and perimysium. Endothelial cells had moderate pleomorphism, organized in vascular channels and forming multifocally solid areas with a significant amount of eosinophilic fibrillar material (fibrin). Sections of muscle neoplasm were subjected to immunohistochemistry with anti-von Willebrand factor primary antibody, which showed a multifocal moderate cytoplasmic immunolabeling of neoplastic endothelial cells.Discussion: There are few reports of striated muscle hemangiosarcoma in cattle. Muscular hemangiosarcomas were reported in a 4-month-old calf in the left cervical trapezius muscle and a 6-year-old Holstein cow with left pelvic limb mass lateral and distal to the knee. Some reports presented hemangiosarcoma in the iliopsoas muscle, left cervical trapezius muscle, pelvic limb muscles and right cervical muscle of the bovine. In the presented report, hemoperitoneum occurred as a result of hemorrhages from muscle hemangiosarcoma. Other studies have demonstrated cavity hemorrhages in joint, pelvic, pleural and cranial cavities associated with hemangiosarcoma. Hemangiosarcoma with regenerative anemia must be distinguished from other diseases that cause anemia. The main differential diagnoses of bovine with anemia are vena cava syndrome, coumarin derivatives poisoning, acute poisoning by Pteridium spp., tick fever, anaplasmosis, babesiosis and trypanosomiasis. Hemangiosarcoma should be differentiated from other lesions as hemangioma, vascular tumor of lymphatic endothelium and perivascular wall tumors. Cases with poorly differentiated morphology should be submitted for immunohistochemistry. In the present hemangiosarcoma case, we have used the von Willebrand factor for immunohistochemistry diagnosis. Expression of angiogenic growth factors such as CD31, vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF) and angiopoietin-1 (Ang-1) have also been used in the diagnosis of vascular proliferation lesions. Hemangiosarcoma in cattle should be included mainly in the differential diagnosis of diseases that cause acute anemia in cattle.Keywords: cattle, neoplasia, hemangiosarcoma, hemoperitoneum, anemia
