In cystic endometrial hyperplasia (CEH)–pyometra syndrome, toxic factors and endometrial remodeling culminate in changes characterized by exudative and degenerative inflammatory reaction. Recent studies on hemodynamic found an increased blood flow and lower vascular resistance in uterine arteries, suggesting color Doppler ultrasound as an adjunctive tool for quantitative assessment of endometrial vascularization during pyometra. The aim of this study was to assess, through contrast-enhanced ultrasound (CEUS) exam, the vascularization in endometrial microvessels in CEH-pyometra in order to evaluate the possibility of application in this syndrome. In twelve female dogs with clinical symptoms related to pyometra, B-mode, color Doppler and CEUS exams were performed. In CEH-pyometra uteri, histopathological examination revealed severe CEH and pyometra, immunohistochemical stain with CD 34 confirmed the presence of angiogenesis. CEUS exams revealed a widespread, intense and rapidly develo...

EnglishThe volume of available and expanding digital information to which Open Access to information contributes entails new challenges for libraries. These, which have always had as objective the access to good quality information, face new challenges that also go through the help in the identification of relevant information to all those who look for them, the so-called Reference Service. Thus, this study has as general objective to assess the role of the reference service in the retrieval of information in the current context of Open Access to scientific information; and as specific objectives: a) define the concept of Open Access; b) define and characterize the Reference Service; c) reflect on the potential of this service with regard to the excellent retrieval of pertinent and relevant information in this immeasurable universe of available information. We chose a methodology of qualitative exploratory through a literature review. It was concluded that the Reference Service can ...

Desde a Declaracao de Budapeste em fevereiro de 2002 que se discute a questao do acesso livre e universal ao conhecimento cientifico, procurando explorar as potencialidades abertas pela tecnologia digital e o modo como os processos e produtos da informacao cientifica se enquadram neste novo contexto. Este trabalho tem como objetivo aferir as potencialidades do resumo cientifico na area das Ciencias da Saude dando-se enfâse ao papel da sua estrutura como elemento chave no cumprimento das funcoes de representacao do conteudo dos documentos em dois contextos distintos: Acesso Restrito (AR) e Acesso Aberto (AA). A metodologia utilizada e qualitativa, subdividida em duas fases, revisao da literatura e estudo de caso, este centrado na analise comparativa dos resumos de duas revistas cientificas de relevo na area da Saude publicadas em distintos contextos: a PLoS One (AA) e a Nature (AR). Os resultados apontam para a compatibilidade estrutural entre os resumos analisados nas duas revistas,...

Now-a-days, while a mature system of preservation and conservation (PAC) technology and methodology exists world wide to achieve the systematic PAC of world's cultural heritage, the PAC programs of Bangladesh National Archives (the custodian of Bangladesh ...

Excess capacity and overfishing are problems in the open-access, common-pool fisheries of the Java Sea. Data development analysis is used to estimate excess fishing capacity and the number of vessels to decommission in three Java Sea fisheries of Indonesia, the purse seine, mini purse seine, and longline. First- and second-best policy measures are discussed to reduce the excess capacity and give sustainable management and development. The importance of incentive design, asymmetric information, and the regulator's principal–agent problem are emphasized in license limitation programs.

Familial glomerular hematuria(s) comprise a genetically heterogeneous group of conditions which include Alport Syndrome (AS) and thin basement membrane nephropathy (TBMN). Here we investigated 57 Greek-Cypriot families presenting glomerular microscopic hematuria (GMH), with or without proteinuria or chronic kidney function decline, but excluded classical AS. We specifically searched the COL4A3/A4 genes and identified 8 heterozygous mutations in 16 families (28,1%). Eight non-related families featured the founder mutation COL4A3-p.(G1334E). Renal biopsies from 8 patients showed TBMN and focal segmental

This paper examines functional aspects of the internet Web Sites that (re)present Greek Higher Educational Departments and Institutes and focuses on the promotion and dissemination of their educational and scientific results. The study conforms to the theoretical guidelines of a systemic approach that produces an overview of the consistencies and the asymmetries that define the impact of a Web Site as a communicative system. Web Sites representing Greek Higher Educational Departments and Institutes are evaluated as communicative systems that promote certain distinctions (that suggest meanings) in the context of the World Wide Web (WWW). The relevant evaluation includes five hundred and one (501) Web Sites and was based on eight (8) criteria. The results of this study hopefully will account for (Greek) Departments' Web Sites to be efficient, interactive and provide their readers with appropriate services.
