Clínica de animais de companhia: uveítes caninas: estudo retrospetivo de 50 casos

O presente relatório pretende descrever as atividades desenvolvidas durante o estágio no Hospital Veterinário do Restelo e apresentar a casuística relativa a este período. É apresentado também um estudo de casos sobre uveítes caninas e monografia sobre o tema. A uveíte é uma das afeções oculares mais frequentes nos cães, muitas vezes associada a outras afeções sistémicas. Foi realizado um estudo retrospetivo com 50 cães que se apresentaram neste Hospital nos anos de 2011 e 2012 com diagnóstico primário de uveíte, com o objetivo de caracterizar a distribuição das uveítes na população canina e avaliar as suas causas, em especial a relação com doenças sistémicas. O número de causas oculares identificadas foi igual ao número de causas sistémicas, o que reforça o importante papel de determinadas afeções sistémicas na etiologia da uveíte; ### Abstract Clinic in Small Animals Canine Uveitis: Retrospective Study of 50 cases The present report aims to describe the activities developed during the traineeship in Veterinary Hospital of Restelo and presents the casuistry relating to this period. It also presents a case study about canine uveitis and a monograph about it. Uveitis is one of the most common ocular diseases in dogs, often associated with others systemic diseases. We conducted a retrospective study in 50 dogs presented at the Hospital in 2011 and 2012 with a primary diagnosis of uveitis, with the purpose of characterizing the distribution of uveitis in the dog population and evaluate their causes, in particularly the relationship with systemic diseases. The number of identified ocular causes was equal to the number of systemic causes, which reinforces the important role of certain systemic conditions in the etiology of uveitis.

Um olhar sobre o "Bau" do laboratório de Física da ESNA : Contributo para a valorização da herança do Colégio de S. Fiel

No final do século XIX, o Liceu de Castelo Branco debatia-se com baixa frequência de alunos. A isso não foi alheio a abertura do Colégio de S. Fiel, colégio jesuíta. A situação de ''penúria" da escola pública contrastava com S. Fiel. Este estabelecimento de ensino, com um plano de estudos eclético, bons laboratórios e material científico actual e de qualidade, adquirido a prestigiados fabricantes de instrumentos, permitiu a actividade prática desenvolvendo nalguns alunos um gosto pelas Ciências. Com a expulsão dos jesuítas, em 191O, o liceu herdou os dispositivos do colégio. Muitos destes dispositivos foram perdendo valor de utilização comparados com outros de fácil manipulação. Arrumados dispersamente e por vezes desmembrados, urgia voltar a juntá-los de novo recriando a colecção do Colégio S. Fiel. Este aspecto exigiu um trabalho de "mãos na massa" que nos mobilizou fortemente, já que ia consistindo em pequenas descobertas diárias, contribuindo para o enriquecimento deste espólio. O objectivo principal do trabalho aqui apresentado centrou-se na valorização dos dispositivos constituintes desta colecção explorando a sua origem, a sua função e a sua contextualização, didáctica na época, reconhecendo a sua actualidade científica e pedagógica. ABSTRACT; ln the end of the 19th Century, the Grammar School of Castelo Branco was facing a situation of low attendance of students. That was due to the opening of S. Fiel boarding school, a Jesuit school. The situation of «penury» of state schools contrasted with that of S. Fiel. This boarding school, with eclectic curricula, good labs and updated, quality, scientific material acquired from very prestigious manufacturers of instruments enabled the practical activity, developing in some students the taste for science. With the expelling of the Jesuits, m 1905, the Grammar School of Castelo Branco inherited the instruments and materials from S. Fiel boarding school. Many of these materials were no longer user-friendly compared with others which could be handled more easily. Kept in different places and sometimes scattered, it was absolutely necessary to collect them again, in order to recreate the collection of S. Fiel. This aspect demanded «to be working on », which encouraged us more and more as small daily discoveries were being made, contributing therefore, to improve the quality of this asset. The main purpose of the work presented here, is concerned with the importance and worth given to the materials which constitute this collection, exploring its origin, function, didactic and time context and recognizing its scientific and pedagogic modernity.

O fim sob o olhar da inocência : Representações da morte na infância

A morte suscita-nos grande inquietação (e.g., Oliveira, 2008). Especialmente entre as crianças, perdidas na incompreensão, silêncio e repressão psicológica por parte dos adultos. Nesta investigação averiguamos as representações sociais, da morte e da vida, entre crianças dos 8 aos 11 anos, escolarizadas de ambos os sexos. As meninas representam a morte pelo medo que suscita, e pela sua dimensão ritualista, enquanto que os meninos a percecionam sobretudo por sentimento de mal-estar e impotência. Sobre a vida, os meninos evidenciam uma visão mais hedonista do que elas, que salientam a interação com o outro e as questões afetivo-emocionais. As representações das raparigas aproximam-se mais das dos sujeitos de 10-11 anos, enquanto que as dos rapazes se aproximam das dos participantes de 8-9 anos. Esperamos contribuir para o modo como as crianças representam a morte e, para uma educação para a morte e para a vida. ABSTRACT; Death rouses great uneasiness (e.g., Oliveira, 2008). Especially among children who are lost amid the incomprehension, silence and psychological repression of adults. This research examines social representations of life and death among school attending children of both sexes, between the ages of 8 and 11 years old. Girls represent death for both the fear it rouses and its ritualistic dimension, while boys mostly perceive it as a feeling of uneasiness and impotence. Regarding life, boys show a more hedonistic vision than girls, who give relevance to interacting with. others, and to affective and emotional issues. The representations of girls are closer to those of the 10-11-year-old subjects, while the representations of boys are closer to those of the 8-9-year-old participants. We hope to contribute to the way children represent death, and to an education on death and life.

A real time Taqman RT-PCR for the detection of rabbit hemorrhagic disease virus 2 (RHDV2)

As key prey, the wild rabbit downsize constitutes a major drawback on the endangered Iberian lynx (Lynx pardinus) re-introduction in the Iberia. Several captive breeding units mostly located in Alentejo, endeavour the wild rabbit repopulation of depleted areas assigned for the lynx re-introduction. Here we report an RHDV2 outbreak that occurred in early 2016 in a wild rabbit captive breeding unit located in Barrancos municipality. The estimated mortality rate between March and April 2016 was approximately 8.67%. Anatomopathologic examination was carried out for 13 victimized rabbits. Molecular characterization was based on the complete vp60 capsid gene. The 13 rabbit carcasses investigated showed typical macroscopic RHD lesions testing positive to RHDV2- RNA. Comparison of the vp60 nucleotide sequences obtained from two specimens with others publically available disclosed similarities below 98.22% with RHDV2 strains originated in the Iberia and Azores and revealed that the two identical strains from Barrancos-2016 contain six unique single synonymous nucleotide polymorphisms. In the phylogenetic analysis performed, the Barrancos-2016 strains clustered apart from other known strains, meaning they may represent new evolutionary RHDV2 lineages. No clear epidemiological link could be traced for this outbreak where the mortalities were lower compared with previous years. Yet, network analysis suggested a possible connection between the missing intermediates from which the strains from Barrancos 2013, 2014 and 2016 have derived. It is therefore possible that RHDV2 has circulated endemically in the region since 2012, with periodic epizootic occurrences. Still, six years after its emergence in wild rabbits, RHDV2 continues to pose difficulties to the establishment of natural wild rabbit populations that are crucial for the self-sustainability of the local ecosystems.

Emergy analysis of a silvo-pastoral system, a case study in southern Portugal

The Mediterranean silvo-pastoral system known as Montado, in Portugal, is a complex land use system composed of an open tree stratum in various densities and an herbaceous layer, used for livestock grazing. Livestock also profit from the acorns, and the grazing contributes to avoid shrub encroachment. In the last 20 years, subsidies from the European Union have greatly promoted cattle rearing in this system and the introduction of heavy breeds, at the expense of sheep, goats or the native cattle breeds. The balance of the traditional system is thus threatened, and a precise assessment of the balance between the different components of the system, therefore is highly needed. The goal of this study was to gain a better under- standing of a Montado farm system with cattle rearing as the major economic activity by applying the emergy evaluation method to calculate indices of yield, investment, environmental loading and sustainability. By integrating different ecosystem components, the emergy evaluation method allows a comprehensive evaluation of this complex and multifunctional system at the scale of an individual farm. This method provides a set of indices that can help us understand the system and design management strategies that maximize emergy flow in the farm. In this paper, we apply the emergy evaluation method to a Montado farm with cattle rearing, as a way to gain a better understanding of this system at the farm scale. The value for the transformity of veal (2.66E?06 sej J-1) is slightly higher, when compared to other systems producing protein. That means that the investment of nature and man in this product was higher and it requires a premium price on the market. The renewa- bility for Holm Oaks Farm (49 %), lower than for other similar systems, supports the assumption that this is a farm in which, comparing with others, the number of purchased inputs in relation to renewable inputs provided by nature, is higher. The Emergy Investment Ratio is 0.91 for cattle rearing compared to a value of 0.49 for cork and 0.43 for firewood harvesting, making it clear that cattle rearing is a more labor demanding activity comparing with extractive activities as cork and firewood harvesting.
