Diagnóstico diferencial entre doença celíaca e sensibilidade ao glúten não-celíaca: uma revisão
Gluten consumption has been associated with a spectrum of diseases called “gluten-related disorders”. This review highlights the epidemiological, pathophysiological and diagnostic features of celiac disease and non-celiac gluten sensitivity. Celiac disease results from a complex interaction between genetic factors (specific HLA alelles) and environmental factors (gluten intake); diagnosis relies, in most cases, on serological tests and intestinal biopsy. Non-celiac gluten sensitivity is a non-allergic, nonautoimmune disease of increasing importance. Diagnosis is based on exclusion of associated diseases and confirming that the patient’s symptoms are linked with gluten consumption. While both may have similar and overlapping clinical manifestations, a systematic assessment enables effective differential diagnosis
High-energy extracorporeal shockwave therapy in a patellar tendon animal model: a vascularization-focused study
OBJECTIVE: The aim of this study was to analyze the effect of high-energy extracorporeal shockwave therapy on tendon angiogenesis in the patellar tendons of rabbits. We sought to investigate whether different voltage and number pulses modify the angiogenesis pattern. INTRODUCTION: High-energy extracorporeal shockwave therapy is an option in the treatment of orthopedic diseases such as chronic tendonitis. Despite its potential clinical applicability, there have been few studies on this technique that examine both its clinical effectiveness and its effect on angiogenesis. METHODS: High-energy extracorporeal shockwave therapy was applied at the tibial insertion of the left patellar ligament in 30 rabbits that were separated into six groups that differed in terms of the voltage and number of pulses that were applied by high-energy extracorporeal shockwave therapy. The tibial insertion in the right legs of the animals was used as the control. After six weeks, we performed histological analysis on the region and quantified the number of blood vessels. RESULTS: No significant differences in the number of blood vessels between the left and right patellar tendons were found within groups. Additionally, no significant differences in the number of blood vessels in the left patellar tendons were found between groups. CONCLUSIONS: The application of high-energy extracorporeal shockwave therapy did not cause a change in vascularization in the patellar tendon in rabbits
Livro Verde dos Montados
O Livro Verde dos Montados apresenta diversos objectivos que se interligam:
Em primeiro lugar, o Livro Verde pretende reunir e sistematizar, de uma forma simples e acessível ao público, o conhecimento produzido em Portugal pelos investigadores e técnicos de várias instituições de investigação ou de gestão que estudam o Montado. Assume-se como uma oportunidade de caracterizar o sistema tendo em conta as suas várias dimensões, identificando as principais ameaças à sua preservação assim como os caminhos que podem ajudar à sua sustentabilidade. Não sendo um documento científico, baseia-se no conhecimento científico e pretende constituir a base para uma plataforma de organização, tanto dos investigadores como do conhecimento científico actualmente produzido em Portugal sobre o Montado.Em segundo lugar, o Livro Verde deverá contribuir para um entendimento partilhado do que é o Montado, por parte do público, de técnicos e de especialistas, conduzindo a uma classificação mais clara do que pode ser considerado Montado e de quais os tipos distintos de Montados que podem ser identificados.
Em terceiro lugar, o Livro Verde estabelece as bases para uma estratégia coordenada de disponibilização de informação sobre o sistema Montado, visando o seu conhecimento, apreciação e valorização pela sociedade portuguesa no seu conjunto. Deste modo, o Livro Verde poderá constituir um instrumento congregador e inspirador para a realização de acções de sensibilização e informação sobre o Montado.
Em quarto lugar, pretende-se que o Livro Verde contribua para um maior reconhecimento e valorização do Montado como sistema, a nível do desenho das políticas nacionais por parte dos vários sectores envolvidos.Finalmente, o Livro Verde constituirá um documento parceiro do Livro Verde das Dehesas, produzido em Espanha em 2010, de forma a reforçar o reconhecimento e a devida valorização destes sistemas silvo-pastoris no desenho das estratégias e políticas relevantes pelas instituições europeias.
Em suma, os autores pretendem que o Livro Verde dos Montados se afirme como o primeiro passo para uma efectiva definição e implementação de uma estratégia nacional para os Montados
Hung Out to Dry: Choice of Priority Ecoregions for Conserving Threatened Neotropical Anurans Depends on Life-History Traits
Background: In the Neotropics, nearly 35 % of amphibian species are threatened by habitat loss, habitat fragmentation, and habitat split; anuran species with different developmental modes respond to habitat disturbance in different ways. This entails broad-scale strategies for conserving biodiversity and advocates for the identification of high conservation-value regions that are significant in a global or continental context and that could underpin more detailed conservation assessments towards such areas. Methodology/Principal Findings: We identified key ecoregion sets for anuran conservation using an algorithm that favors complementarity (beta-diversity) among ecoregions. Using the WWF’s Wildfinder database, which encompasses 700 threatened anuran species in 119 Neotropical ecoregions, we separated species into those with aquatic larvae (AL) or terrestrial development (TD), as this life-history trait affects their response to habitat disturbance. The conservation target of 100 % of species representation was attained with a set of 66 ecoregions. Among these, 30 were classified as priority both for species with AL and TD, 26 were priority exclusively for species with AL, and 10 for species with TD only. Priority ecoregions for both developmental modes are concentrated in the Andes and in Mesoamerica. Ecoregions important for conserving species with AL are widely distributed across the Neotropics. When anuran life histories were ignored, species with AL were always underrepresented in priority sets

Os primórdios da organização do espaço territorial e da vila cearense: algumas notas
This paper presents, in outline, the action taken by economic agents, representatives of the Church and the Portuguese State in organizing the space of the Captaincy of Ceará in the eighteenth century. The Portuguese State founded towns in strategic locations for better capitalization of the cattle breeder economy, where first settled sesmeiros and the Church. There was no reason or justification of geopolitical nature that demanded technical and financial investments by the Portuguese in the full adequacy of the local conditions to Portuguese urban guidelines. In the face of the late occupation, the article also discusses the late cartographic representation as expressing the lack of interests of the Portuguese administration in relation to a fuller understanding of the region
