Strategies for public engagement on environmental matters:you can lead a horse to water, but can you make it drink?

With no tangible evidence of widespread public engagement in the UK on matters relating to the environment, this article assesses the benefits of adopting the principles of key theoretical models on learning (e.g., Kolb's Experiential Model) in environmental campaigns. In addition, in order to facilitate the transition from environmental knowledge/awareness, to the adoption of proenvironmental behavior, the article reviews some of the key internal and external drivers to achieving sustained behavioral change.

How checking breeds doubt:reduced performance in a simple working memory task

A paradox of memory research is that repeated checking results in a decrease in memory certainty, memory vividness and confidence [van den Hout, M. A., & Kindt, M. (2003a). Phenomenological validity of an OCD-memory model and the remember/know distinction. Behaviour Research and Therapy, 41, 369–378; van den Hout, M. A., & Kindt, M. (2003b). Repeated checking causes memory distrust. Behaviour Research and Therapy, 41, 301–316]. Although these findings have been mainly attributed to changes in episodic long-term memory, it has been suggested [Shimamura, A. P. (2000). Toward a cognitive neuroscience of metacognition. Consciousness and Cognition, 9, 313–323] that representations in working memory could already suffer from detrimental checking. In two experiments we set out to test this hypothesis by employing a delayed-match-to-sample working memory task. Letters had to be remembered in their correct locations, a task that was designed to engage the episodic short-term buffer of working memory [Baddeley, A. D. (2000). The episodic buffer: a new component in working memory? Trends in Cognitive Sciences, 4, 417–423]. Of most importance, we introduced an intermediate distractor question that was prone to induce frustrating and unnecessary checking on trials where no correct answer was possible. Reaction times and confidence ratings on the actual memory test of these trials confirmed the success of this manipulation. Most importantly, high checkers [cf. VOCI; Thordarson, D. S., Radomsky, A. S., Rachman, S., Shafran, R, Sawchuk, C. N., & Hakstian, A. R. (2004). The Vancouver obsessional compulsive inventory (VOCI). Behaviour Research and Therapy, 42(11), 1289–1314] were less accurate than low checkers when frustrating checking was induced, especially if the experimental context actually emphasized the irrelevance of the misleading question. The clinical relevance of this result was substantiated by means of an extreme groups comparison across the two studies. The findings are discussed in the context of detrimental checking and lack of distractor inhibition as a way of weakening fragile bindings within the episodic short-term buffer of Baddeley's (2000) model. Clinical implications, limitations and future research are considered.

Horse stable environment: what to expect regarding fungi and particles occupational exposure?

The simultaneous presence of fungi and particles in horse stable environment can create a singular exposure condition because particles have been reported has a good carrier for microorganisms and their metabolites. This study intends to characterize this setting and to recognize fungi and particles occupational exposure.

Confirmation of Elsey virus infection in a Queensland horse with mild neurologic signs

In 2011, a 2-year-old horse in northern Queensland, Australia, was reported to have developed mild neurologic signs, and a blood sample was submitted for laboratory investigation. Virus isolation was performed using the blood sample, and an orbivirus was isolated. This was confirmed to be a strain of Elsey virus (ELSV) after transmission electron microscopy and nucleotide sequencing. The nucleotide sequence was compared with those in GenBank, and had 100% identity with ELSV previously reported from the Northern Territory, Australia. ELSV is taxonomically closely related to Peruvian horse sickness virus.

Distal limb osteoarthritis in the horse

The aim of this thesis was to study two objective methods of osteoarthritis (OA) diagnosis in horses and use them on the assessment of new intra-articular treatments. The studied methods were a new inertial-sensor based system of lameness detection and cartilage biomarkers in serum. It was found that distal limb flexion is significantly correlated to the presence of metacarpo-phalangeal OA in hind limbs and that inertial-sensors are sensitive in detecting asymmetry in these cases. A positive and significant correlation was observed between Coll2-1 concentration in serum and the presence of joint disease in males and young horses. Fib3-2 measurement has good potential to be used since it is not influenced by sex or age. Using an experimental model of OA, adipose stem cells pre-activated with interferon-gamma decreased joint inflammation and radiographic lesions. In clinical cases, a single injection of high-concentrated and high-molecular weight hyaluronic-acid decreased joint inflammation and biomarkers’ concentration; OSTEOARTRITE DO MEMBRO DISTAL NO CAVALO Resumo: A finalidade desta tese foi estudar dois métodos de diagnóstico objetivo de osteoartrite (OA) em equinos e aplicá-los na avaliação de novas terapias intra-articulares. Utilizou-se um sistema de sensores de movimento e foi avaliada a concentração de biomarcadores de cartilagem no soro. Concluiu-se que a flexão distal positiva está correlacionada com OA na articulação metacarpofalângica nos membros posteriores e que os sensores são sensíveis na detecção de assimetria nestes casos. Existe uma correlação positiva e significativa entre as concentrações de Coll2-1 e a presença de doença articular, sobretudo em machos e jovens. A dosagem de Fib3-2 tem utilidade por não ser influenciada pelo sexo nem idade. Num modelo experimental da doença, a terapia à base de células estaminais reduziu a inflamação articular e as lesões radiográficas. Em casos clínicos, o tratamento com ácido-hialurónico de alta concentração e peso molecular provoca uma diminuição da inflamação articular e dos biomarcadores no soro.

Aplicação de microssatélites na crioconservação da diversidade genética do cavalo lusitano

O género Equus teve origem na América do Norte e alguns exemplares migraram para a Eurásia pelo Estreito de Bering, durante a última glaciação. No fim da glaciação, todos os cavalos do continente americano extinguiram-se, mas sobreviveram nas estepes da Eurásia, na Peninsula lbérica e nas florestas da Europa Ocidental e Central. O cavalo Lusitano teve a sua origem em cavalos selvagens e domesticados da Peninsula lbérica, ocorrendo uma mistura com outros animais trazidos por eventos migratórios ocorridos no passado. Os cavalos deste gene pool contribuiram para o desenvolvimento de outras raças modernas na Europa e foram mais tarde introduzidos e dispersos pelo continente Americano, tornando-se fundadores de numerosas raças do novo mundo. A raça Lusitana é uma raça equina autóctone portuguesa, com especial relevancia económica no panorama nacional e internacional. Apesar de não ser uma raça ameaçada, alguns autores defendem que a informação genealógica disponivel (pedigrees) indica que uma utilização excessiva de um reduzido número de reprodutores machos esta a diminuir a diversidade genética da raça, tendo como consequência o aumento da consanguinidade e a diminuição do tamanho efetivo da população para cerca de metade dos valores recomendados pela FAO. No entanto, a anàlise da diversidade genética com base em 16 microssatélites (Marcadores de DNA) a um grupo de 2699 machos da raça Lusitana, nascidos entre 1985 e 2010 e inscritos como reprodutores no Livro Genealógico da raça, revelou um elevado nível de diversidade, idêntico ao encontrado na maioria das raças equinas. Dada a crescente relevância da Crioconservação, omo estratégia complementar para a conservação da diversidade genética in situ, e tendo em conta que não existe criopreservação de oocitos, embriões ou sémen, do cavalo de raça Lusitana em Banco de Genes, selecionaram-se 62 machos reprodutores (garanhões) com interesse genético para a criopreservação de sémen, quer no sentido de preservar a diversidade da raça quer no da salvaguardar em caso de calamidade; ABSTRACT: The genus Equus originated in North America and some exemplary migrated to Eurasia through the Bering Strait during the last glaciation. By the end of the last glaciation, all horses on the American continent became extinct but the genus survived in the steppes of Eurasia, in the Iberian Peninsula and on the Central and West Europe forests. The Lusitano horse breed has its origins in wild and domesticated horses of the Iberian Peninsula, where a mixture with other animals brought by migratory events in the past occurred. The horses of this gene pool contributed to the development of other modern breeds in Europe and were later introduced and spread throughout the American continent, becoming founders of numerous breeds of the New World. The Lusitano horse breed, is a Portuguese native equine breed, with special economic relevance in the national and international scene. Although not being an endangered breed, some authors argue that the available genealogical information (pedigrees) indicates that an excessive use of a limited number of stallions is decreasing the genetic diversity of the breed, resulting in the increase of inbreeding and on the decrease of the effective population size to about half of the values recommended by FAO. However, the analysis of genetic diversity based on 16 microsatellites (DNA markers) in a group of 2699 males of the Lusitano horse breed, born between 1985 and 2010 and registered as Stallions in the Studbook, revealed a high level of diversity similar to that found in the majority of equine breeds. Given the growing relevance of Cryopreservation as a complementary strategy for the conservation of genetic diversity in situ and, taking into consideration the inexistence of criopreservation for oocytes, embryos and semen, in a Gene Bank, for the Lusitano horse breed, 62 breeding males (stallions) with genetic interest for semen cryopreservation were selected in order either to preserve the diversity of the breed or as safeguard in case of calamity.
