Efeitos da inibição da cox-2 no sistema cardiovascular de cães

Os anti-inflamatórios não esteroidais (AINEs) estão entre os medicamentos mais prescritos em todo o mundo, tanto na medicina humana, como na medicina veterinária. Atualmente os AINEs são classificados em não seletivos (convencionais ou clássicos), que são os mais antigos, e seletivos para COX-2 ou coxibes. Alguns estudos constataram uma possível relação entre os inibidores COX-2 seletivos e os efeitos adversos no sistema cardiovascular. Devido a isso, objetivou-se realizar um levantamento de pesquisas que comprovem os efeitos cardiovasculares ocasionados por essa classe farmacológica utilizando livros e artigos das bases de dados PubMed, Periódicos da Capes e SciELO que respondessem à pergunta: a inibição da COX-2 acarreta efeitos adversos para o sistema cardiovascular?. Do total de resultados encontrados, foram utilizados 16 artigos. Os trabalhos mostraram que o uso de inibidores da COX-2 alterou o perfil de coagulação para uma tendência trombótica, além de diminuir a resposta vasodilatadora gerada na resposta inflamatória. Diante dos resultados obtidos através desses estudos, conclui-se que a COX-2 desempenha papel fisiológico no sistema cardiovascular, facilitando a não formação de trombos nos vasos sanguíneos, e, portanto, que sua inibição favorece a coagulação. Assim, os fármacos que inibem a COX-2 devem ser prescritos com cautela, levando-se em consideração o perfil de coagulação do paciente

Confidências: os ensaios críticos de Kate Chopin

Between 1894 and 1899 Kate Chopin (1850 – 1904), one of the main exponents of American Realism and Feminism, published seven critical essays in newspapers and journals. To this number, it might be added the sketch ―Confidences‖ and the two first entrances of Impressions, her second diary, totalizing nine texts. These texts unveil a refined critical spirit, an outspoken and edge-cutting style in writing, sometimes sarcastically merciless, and an eager reader, all of them aspects that would be put into practice by the Feminist criticism expressed in the author‘s novels and short stories. To introduce and briefly discuss these essays are the main purposes of this paper.

Uma festa de princesa para a Gata Borralheira

We analyze in this paper how the enunciator of two Brazilian magazines (Capricho and Atrevida) builds his enunciatee. Our analysis is based on French Semiotics and on woks by Eric Landowski (2002), whose studies about semiotization of social behavior point out the fact that the society excludes people who are not similar to those who belong to groups considered as a reference. In the textual construction, we noticed that the enunciator uses figures which allow us to visualize euphoric ways of life. However, we intend to verify if the figures show if these magazines are made for enunciatees from different social class or not. This verification is important as there is also a disphoric way of life, i.e., a segregated or excluded way of life.

Práticas de gestão da melhoria contínua e aprendizado e suas contribuições para a capacidade de inovação na indústria de construção naval do Brasil

After years of stagnation, the naval construction industry in Brazil has been experiencing a period of recovery caused by investments in the oil and gas sector and the implementation of governmental programs that aimed to regenerate it. However, efforts in learning and innovations are needed in order to reinsert the country in this activity and achieve international levels of competitiveness. Based on literature about learning processes and continuous improvement practices and their impact in the innovative and productive processes, this paper aims to identify the main tendencies, mechanisms and procedures to improve the construction and management processes in the Brazilian naval construction industry. The methodology used for the data analysis classifies obtained information from magazines and annals of congresses of the sector, according to the established analysis categories (phenomena). Such categories study information related to the productive and technological processes of the industry, the main internal and external relations of the industrial park, the management of resources and processes, policies, investments, etc. The data was collected in the period 2004-2010, and more than 500 registers that show a dominance of the investment phenomenon, especially in the increase of productive capacity, were catalogued. In addition to this, there is evidence of modernization in the manufacturing plan and the equipment, diverse forms of cooperation, implementation of human resources management practices and engineering or processes and products. Hence, a process of catching up governs and is guided by modernization and increase training in this industry.

Avaliação da via aérea superior em pacientes classe III submetidos à cirurgia ortognática: revisão de literatura

Introduction: The configuration and dimensions of the upper airway are determined by anatomical structures such as soft tissues, muscles and craniofacial skeleton, composing or surrounding the pharynx. Anatomical abnormalities of the soft tissues and / or craniofacial skeleton may become more narrow upper airway. The orthognathic surgery, which is used in the correction of dentoskeletal deformities, also causes changes in the upper airway. Objective: In view of the facts presented, this article aims to review the literature on the changes of the upper airway in patients’ class III undergoing orthognathic surgery. Methodology: International Literature on Health Sciences (Pubmed ) and Port Journals CAPES original and review published between 1990 and 2010, in two bibliographic databases articles were selected. Results: thirty-nine (39) articles were selected for writing this review. Conclusion: The upper airway deformity and dental- skeletal class III should be carefully evaluated prior to orthognathic surgery and whenever surgical planning permit should prefer the maxillary advances to mandibular setbacks
