A doação de sangue é uma necessidade para países e pessoas. O crescimento da violência, dos acidentes de trânsito, junto com a disseminação de doenças transmissíveis e com o envelhecimento da população, trazem dificuldades aos hemocentros e instituições de saúde para assegurar um adequado e consistente suprimento de sangue para atender às necessidades dos pacientes. São realizadas campanhas via TV, rádio, jornal, etc, e foi observado que as pessoas se sensibilizam com a necessidade de sangue,...

2018-04-01

Full Text Available Este estudo se propõe à reflexão sobre as obras de Roberto Drummond, mais especificamente Sangue de Coca-Cola - romance que integra o ciclo Coca-Cola do autor. A pesquisa se propõe a demonstrar que a arte pop não é estática e que se materializa através da interação com outras linguagens e com a cultura. Assim, o trânsito entre distintos campos discursivos como a Filosofia, Sociologia e a Teoria da Literatura apresentou-se, então, como a estratégia mais apropriada para discutir a questão.   Palavras-chave: Carnavalização, Literatura Pop, Sangue de Coca-Cola.

Full Text Available Esta pesquisa mostra o perfil social dos doadores que participaram do 7° Dia de Doação de Sangue na UERJ e tem como objetivo a análise dos fatores que incentivaram a comunidade a doar sangue e a avaliação da divulgação de tal evento entre os doadores. Utilizou-se o método descritivo e a técnica de investigação social através de um questionário composto de 14 perguntas, sendo sete objetivas e sete subjetivas, que foi respondido pelos doadores no ato da doação de sangue. A amostra foi constituída de 129 doadores. A campanha de doação de sangue foi realizada no "Campus" da Universidade do Estado do Rio de Janeiro, no dia 24 de abril de 1991, das 08 às 17 horas. Como resultado pode-se observar uma amostra composta em sua maioria de adultos jovens, do sexo masculino, de cor branca, solteiros, estudantes do 3° Grau, tendo a solidariedade como a principal razão para doar sangue. Recomenda-se aos organizadores do evento maior divulgação das futuras campanhas, visando com isso uma participação efetivamente significativa da comunidade como um todo.

Full Text Available Objetivo: o estudo tem como objetivo discutir os significados apreendidos pelos não doadores de sangue, considerando o contexto e as consequências para a atuação do enfermeiro na hemoterapia. Método: optou-se pela abordagem qualitativa, com o referencial teórico do Interacionismo Simbólico e o método daGrounded Theory. A produção de dados foi realizada por entrevista intensiva com sujeitos de três grupos amostrais de um Hospital Universitário da Cidade do Rio de Janeiro. Resultados: o fenômeno gerou duas categorias de análise: "Percebendo a questão do sangue" e "Refletindo sobre as campanhas de doação de sangue". Observou-se que o ambiente do não doador é composto pelo contato com o outro e com as informações que este possa alcançar, inclusive a mídia. Conclusão: estas foram as principais bases para o conhecimento sobre a doação de sangue, que fazem nexo com as suas crenças, cultura e valores. Portanto, todos estes aspectos devem ser considerados pelo enfermeiro que atua na captação de doadores.

Aspectos morfológicos e ultraestruturais de células sanguíneas de Crotalus durissus terrificus

Lívia M. Kindlovits

Full Text Available RESUMO: A avaliação hematológica, de importância comprovada como um meio auxiliar de diagnóstico ao clínico de pequenos animais domésticos, vem se tornando comum em animais selvagens não apenas para a clínica, mas para a avaliação do manejo e como estudo auxiliar para a fisiologia das várias espécies. Tendo em vista o aumento da demanda para a produção de várias drogas de importância farmacêutica, a criação de serpentes peçonhentas vem se tornando comum a ponto destes animais já serem reconhecidos como sendo de produção. O conhecimento do manejo e da clínica destes animais ainda é escasso e a mortalidade é elevada nos criatórios, tornando urgente a ampliação destes. Embora alguns estudos hematológicos já tenham sido realizados em cascavéis (Crotalus durissus os dados analisados ainda são insipientes, notadamente em relação à caracterização das células do sangue e poucos estudos em microscopia eletrônica foram realizados em serpentes. Com o objetivo de caracterizar as células sanguíneas morfologicamente, sob microscopia óptica e ultraestrutural, foram coletadas amostras de sangue de 52 de indivíduos da subespécie Crotalus durissus terrificus para a realização de esfregaços sanguíneos e avaliação ultraestrutural. Concluiu-se que a coloração hematológica de Giemsa permite a avaliação morfológica e a diferenciação das células sanguíneas em serpentes assim como a visualização de hemoparasitos. A avaliação ultraestrutural permite evidenciar as organelas celulares e a diferenciação entre as células, inclusive entre os tipos leucocitários, porém ainda são necessários outros estudos para que seja elucidada a hipótese da existência dos eosinófilos na espécie estudada assim como é necessária melhor caracterização dos grânulos dos azurófilos para que se confirme uma possível diferença entre os monócitos típicos e os azurófilos.

Full Text Available O Brasil apresenta alta prevalência de hemoglobina S, com nítidas diferenças regionais marcadas pelos processos de miscigenação da população. A presença desta hemoglobina tem sido objeto de estudo, não só em pacientes com anemia falciforme (homozigotos para hemoglobina S - Hb SS, mas também em portadores desta variante de hemoglobina em heterozigose (Hb AS. As complicações clínicas dos portadores são influenciadas por fatores genéticos e ambientais. De acordo com a portaria 1376 de 19 de novembro de 1993 para Normas técnicas de coleta, processamento e transfusão de sangue, componentes e derivados, do Ministério da Saúde, deve ser realizada a detecção de hemoglobinas anormais em doadores de sangue. Diante desta normatização e às taxas de hemoglobina S em nossa população, objetivamos no presente trabalho a identificação da hemoglobina S, utilizando técnicas de triagem utilizadas na rotina de Bancos de Sangue, como o kit de identificação para hemoglobina S da Diamed, comercializado pela designação ID-Hb S, e o teste de solubilidade. Os casos que apresentaram positividade nesta triagem foram posteriormente confirmados em eletroforese em pH alcalino e ácido. Do total de 5.416 doadores de sangue analisados pelo teste de triagem (ID - Hb S Diamed e solubilidade, 50 (0,92% apresentaram hemoglobina S. Após confirmação eletroforética evidenciamos a compatibilidade das técnicas em 100 % dos casos analisados. O teste da Diamed apresenta custo de R$ 1,20 por doador e o de solubilidade R$ 0,14. Pelos resultados obtidos sugerimos o uso do teste de solubilidade como de escolha, para triagem de hemoglobina S em bancos de sangue, não só pela eficácia e praticidade, como também pelo baixo custo.

Full Text Available La fisiopatología de la esclerosis múltiple es incierta; la hipótesis más fundada es la existencia de un proceso autoinmune en el que existe predisposición genética. El sistema de grupos sanguíneos está compuesto por antígenos fácilmente detectables, por lo que constituye excelente marcador genético. Para determinar frecuencia de distribución de los grupos sanguíneos en pacientes con esclerosis múltiple, se estudiaron 70 enfermos, de quienes se obtuvieron datos demográficos, clínicos y de escalas evolutivas. Se seleccionaron 180 controles al azar simple mediante muestreo multietápico del universo integrado por 4 747 donantes de sangre. Se determinaron los grupo sanguíneos ABO y RhD. Se calculó X² con precisión del 95 % e intervalo de confianza de las diferencias porcentuales. En ambos grupos fue más frecuente el RhD+ (85,7 % casos y 90 % controles. El grupo sanguíneo A estuvo en el 60 % de los pacientes y el grupo O predominó en los donantes (55 %, con diferencia significativa p=0,003 y OR=2,85. De acuerdo con este estudio, existe una asociación entre el grupo sanguíneo A con la esclerosis múltiple.The physiopathology of multiple sclerosis is uncertain. The best founded hypothesis is the existence of an autoimmune process in which genetic predisposition plays a role. The system of blood groups consists of easily detectable antigens; therefore, it is an excellent genetic marker. To determine the distribution frequency of blood groups in patients with multiple sclerosis, 70 ill persons were studied, about whom demographic, clinical and evolutionary scale data were obtained. 180 controls were selected by simple random multistage sampling of a universe of 4 747 blood donors. Blood groups ABO and RhD were determined. X² was calculated with a 95% accuracy and confidence interval of percent differences. RhD+ was more frequent in both groups (85.7 % cases and 90% controls. Blood group A was found in 60 % patients, whereas

Na primeira fase, quando submetemos sangue deles retirado a 2.500 e 5.000rad, com associação ou não de metronidazol, não obtivemos sucesso, já que todos os animais antes sem a parasitose apresentaram parasitemia e morreram após inoculação do sangue irradiado. Porém, ocorreu êxito parcial na segunda fase, ao serem empregados 10.000 e 15.000rad, porquanto 20% e 40% dos roedores, respectivamente, embora tenham ficado infectados, sobreviveram, com posterior negativação quanto à presença do P. berghei.This study was carried out to evaluate the fortuitons advantage of using gamma irradiation in the prophylaxis of transmissible malaria by blood transfusion, with mice as the experimental model. In the first step, when the infected blood with Plasmodium berghei was submitted to 2,500rad and 5,000rad, with or without metronidazol, there was no success, because the animals presented parasitaemia and died after inoculation of irradiated blood. However, there was partial success in the second step, when the infected blood received 10,000 and 15,000rad, and was inoculated in mice, which showed infection, and presented a survival rate of 20% and 40%, respectively, with later negativation of blood infected by P. berghei.

Full Text Available Doze novilhos foram utilizados para comparar os resultados hemogasométricos de sangue arterial e venoso. Esses animais foram divididos em três grupos idênticos, recebendo: 1- dieta balanceada, proporcionando ganho de peso de 600g/d; 2- dieta de mantença em proteína e energia e 3- dieta com teores 20% abaixo da mantença. Amostras de sangue arterial (artéria auricular caudal e venoso (veia jugular foram colhidas por 11 quinzenas consecutivas, num total de 132 amostras. Ao término do experimento, os animais dos grupos 2 e principalmente 3 apresentaram acidose metabólica moderada. Maiores valores de pH e de pO2 foram constatados no sangue arterial enquanto os teores de bicarbonato, TCO2, BE e pCO2 foram superiores no sangue venoso. Existiram altas correlações entre os valores do sangue arterial e venoso para o pH (r = 0,81, bicarbonato e TCO2 (r = 0,94, sendo esta correlação média, mas significativa, no caso da pCO2 (r = 0,56 e inexistente na pO2 (r= -0,06. Quanto maiores foram os valores de pCO2 maiores foram os teores de bicarbonato (r = 0,54 e TCO2 (r =0,56. Apesar das discrepâncias de pH, das concentrações de bicarbonato, TCO2, e mesmo de pCO2 obtidos no sangue venoso e arterial, é possível estimar, adequadamente, a partir do primeiro esses valores nas amostras arteriais em novilhos normais e com moderado grau de acidose metabólica. Nos casos de alterações respiratórias, amostras de sangue arterial devem ser colhidas para determinação de pO2. A colheita de sangue venoso foi mais facilmente realizada que do sangue arterial.Twelve steers were used to compare the blood gas and acid-base status. The animals were randomly divided in three equal groups according to the following diets: 1- adequate, for gaining 600g/head/d ; 2- protein and energy levels to meet the maintenence; 3- protein and energy 20% below the maintenance levels.

Full Text Available Neste trabalho é proposta uma estratégia simples para determinação simultânea de nitrito e amônia empregando spot test e imagem digital. O método é baseado na reação do nitrito com a sulfanilamida, formando um cátion de diazônio que posteriormente é acoplado ao dicloreto de N-(1-nafitil etilenodiamina formando uma diazo composto de coloração rósea. A determinação da amônia foi realizada empregando a reação de berthelot modificada, onde o íon amônio em presença de salicilato, nitroprussiato e hipoclorito reage formando um composto de coloração verde. Os sinais analíticos foram obtidos a partir das intensidades de coloração por imagem digital no spot test do produto da reação. Após otimizações do sistema de análise e detecção, as seguintes figuras de mérito foram obtidas: concentração linear entre 0,2 a 10,0 mg L-1 para nitrito e 1,0 a 10,0 mg L-1 para a amônia. Os limites de detecção para o nitrito e amônia foram 0,05 mg L-1 e 0,27 mg L-1, respectivamente. A estratégia proposta foi aplicada com sucesso na determinação de nitrito e amônia em amostras de água subterrânea da zona urbana da cidade de Barreiras-Ba.

Full Text Available O presente trabalho teve como objetivo avaliar o uso de algoritmo de otimização na determinação de tipos funcionais de animais da raça Braford para diferentes condições ambientais. Foram utilizados algoritmos específicos de otimização por meio do progama computacional SYNCSA, com o objetivo de determinar subconjuntos ótimos de atributos que definem diferentes tipos funcionais, tendo em vista a eficiência de utilização da pastagem pelos animais. Tais algoritmos estão fundamentados na definição de matrizes de incidência que relacionam as variáveis de interesse. No presente estudo, a matriz B definiu a relação animais x medidas corporais; a matriz W, a relação produtividade acumulada x graus de sangue; e a matriz E, a relação graus de sangue x ambientes (com e sem restrição alimentar. Os resultados mostraram a existência de três tipos funcionais: animais de maior estrutura corporal; animais de estrutura intermediária e animais com menor estrutura, com exceção do atributo largura do peito. Os animais de maior estrutura corporal obtiveram 30 e 47,7kg a mais de terneiros desmamados, no ambiente sem restrição alimentar, que os animais de estrutura corporal média e pequena, respectivamente. No ambiente com restrição alimentar, o tipo de animal de estrutura média apresentou melhor desempenho produtivo, sendo este 18,5 e 36,8% superior aos tipos de maior e menor estrutura corporal, respectivamente. Os resultados deste trabalho demonstram que o algoritmo criado para determinação de tipos funcionais pode ser utilizado na busca do melhor biótipo animal para os diferentes sistemas de produção.This study aimed to evaluate the use of optimization algorithm to determine functional types of animals Braford for different environmental conditions.

Full Text Available Como resultado de inspeções feitas à ilha de Marajó o autor assinala: 1º O mal de cadeiras continua existindo na ilha de Marajó sob a forma enzoótica, ao contrário do que pensavam os criadores, julgando-o extinto. As doenças designadas por estes como "barriga inchada" e "mormo seco", responsaveis pela grande mortalidade dos equinos, foram identificadas pelo autor como tal de cadeiras. 2º O autor considera indispensável para a pesquisa do trypanosoma o processo de inoculação em animais de laboratório, tendo utilizado para esse fim camondongos e ratos brancos. 3º Os surtos epizoóticos anuais coincidem com a época das chuvas, ocasião em que surgem os insetos hematófagos, o que faz pensar no papel desses últimos como transmissores. 4º Os cavalos podem atravessar o ano com trypanosomas no sangue e em estado de saude aparente, constituindo assim depositários do mal de cadeiras. 5º O extermínio da capivara, em consequência do seu aproveitamento econômico não modificou o carater endêmico da doença na ilha de Marajó. 6º O autor observou que os trypanosomas no tubo digestivo de Stomoxys e Tabanideos, ao cabo de 8 horas, apresentavam com movimentos diminuidos e em formas arrendondadas, não conseguindo inoculações positivas com esse material. 7º A saliva de um morcego do gênero Desmodus, que se infectou no laboratório, alimentando-se em animal doente, colhida de modo a evitar lesões da mucosa e consequente contaminação pelos trypanosomas do sangue circulante, mostrou-se incapaz de infectar, por inoculação, animais sensiveis. Este mesmo morcego não transmitiu a doença a um cão, o qual sugou durante 80 dias. Recentemente (1941 empregando um exemplar do gênero Desmodus, também infectado experimentalmente por alimentação em animal de laboratório, conseguimos transmitir o Trypanosoma equinum a uma cobaia normal. Este assunto será ventilado posteriormente.

Full Text Available O presente trabalho objetivou determinar a atividade sérica dos microminerais ferro, cobre, zinco e manganês em 30 equinos atletas da raça Puro-sangue Lusitano (PSL, antes e depois de exercícios, atestados por avaliações clínicas e laboratoriais. Amostras de sangue foram colhidas, antes e imediatamente após 20 minutos de exercício físico de trote e galope suaves realizados em pista de areia, para a realização das dosagens dos microminerais. A concentração dos microelementos foi determinada por espectrofotometria de absorção atômica. Observou-se que após o exercício, a atividade sérica de ferro não sofreu variações (P=0,2365, enquanto os valores de cobre se elevaram significativamente após o treinamento (P<0,001. Já o zinco e o manganês diminuíram após o exercício (P<0,001. Pode-se concluir que o exercício físico de curta duração pode gerar sudorese capaz de alterar as concentrações séricas de ferro, cobre, zinco e manganês em cavalos atletas da raça Puro-sangue Lusitano.

Full Text Available Objetivo: examinar se a taxa de eritroblastos, no sangue da veia umbilical de recém-nascidos, tem relação com a hipoxia perinatal, analisada pelos parâmetros que expressam o equilíbrio ácido-básico (EAB do sangue funicular. Métodos: de recém-nascidos vivos com pelo menos 37 semanas de gestação, assistidos no Hospital de Alvorada-RS, foram coletadas amostras de sangue da veia umbilical antes da instalação da respiração. Parte do sangue foi coletado em frasco contendo EDTA, determinando-se as séries vermelha e branca. No sangue coletado em seringa com heparina, foram determinados valores do pH, pO2, pCO2 e calculado o EAB. Em lâmina corada pelo corante panótico, procedeu-se à contagem manual do número de eritroblastos. A taxa de eritroblastos foi calculada em relação ao número de leucócitos. Resultados: dos 158 casos que compõem o estudo, em 55 as condições perinatais permitiram considerá-los como isentos de acometimento de processo hipóxico. A média da taxa de eritroblastos foi 3,9%, com o desvio-padrão de 2,8%. Os valores mínimo e máximo foram 0% e 10%, respectivamente. Dentre os 158 casos, a taxa dos eritroblastos foi 5,7%, com desvio-padrão de 5,3%. Os valores mínimo e máximo foram 0% e 28%, respectivamente. A aplicação do teste de Pearson a taxa dos eritroblastos e valores dos parâmetros do EAB mostrou correlação significativa para o pH e pCO2. A elaboração da curva ROC revelou que 5% de eritroblastos e pH de 7,25 representam pontos de corte que contrabalançam a sensibilidade e especificidade (54% e 56%, respectivamente. Dos 23 conceptos com taxa de eritroblastos maior que 10%, 7 (30,4% estavam acidóticos, 11 (48,7% eram grandes para a idade gestacional, 3 (13% eram pequenos para a idade gestacional, 7 (30,4% tinham anemia e em 3 (13% não foram constatadas anormalidades. Conclusões: em recém-nascidos de gestações e partos sem complicações, a taxa de eritroblastos ao nascimento foi menor do

Full Text Available Avaliaram-se farinhas de sangue obtidas pelos métodos de processamento em tambor, convencional e atomização. As farinhas foram submetidas ao processo de extração e fracionamento da proteína para determinação do perfil do tamanho molecular, que foi comparado ao do sangue bovino in natura. Nas amostras, submetidas ou não ao processo de desengorduramento, foram realizadas análises da digestibilidade in vitro da proteína. Para determinação dos coeficientes de digestibilidade dos nutrientes in vivo, foram confeccionadas quatros rações, sendo uma sem farinha de sangue, denominada ração-referência purificada. Para essa etapa, juvenis de tilápia-do-nilo com peso médio inicial de 100,0±5,0 g foram estocados em aquários de 250 L, em delineamento de blocos casualizados, com quatro repetições e dez peixes/unidade experimental. As rações-teste foram obtidas com a introdução de 30% das farinhas de sangue em estudo. O processamento afetou a estrutura proteica original do sangue in natura em condições de alta temperatura e tempo prolongado, efeito traduzido pela alta proporção de peptídeos de baixo peso molecular e aminoácidos livres, correspondendo a baixos valores de digestibilidade da proteína da farinha de sangue nos testes in vivo e in vitro. A farinha de sangue atomizada e a de tambor são eficientemente utilizadas por tilápias-do-nilo. Na farinha de sangue convencional, a proteína teve valor biológico inferior ao das outras duas farinhas. Na formulação de rações contendo farinha de sangue para tilápias-do-nilo, a isoleucina deve ser considerada o primeiro aminoácido limitante, seguida pela metionina+cistina, arginina e treonina, que foram encontradas em níveis críticos para essa espécie, principalmente na farinha de sangue convencional.Three kinds of blood meal coming from different processing conditions (spray-dried, drum-dried and vat-dried blood meals were evaluated.

Full Text Available Hemopoietic progenitor cells give rise to all cellular elements of the blood and are of importance as a potential source of cells used for correction of various pathological conditions. The main objective of this study was to identify and quantitative hemopoietic progenitor cell in antenatal fetal blood, in cord blood at the time of delivery and in adult blood, using monoclonal antibodies to surface markers and flow cytometry. CD34+ cells, most of them probably representing progenitor cells, were detected in prenatal fetal blood as early as the 17th week of gestation. The proportion of these cells showed a tendency to decrease as the pregnancy progressed. Within the population of CD34+ cells, a relatively low proportion (less than 1% were negative for the surface marker CD33 or HLA-Dr, indicating a population of primitive stem cells, i.e., progenitor cells no committed to a specific lineage. On the contrary, another group coexpressed CD33 or HLA-Dr, being more mature progenitor cells already committed to differentiate along a specific lineage. The percentage of CD34+ obtained in blood of adult patients after mobilization with chemotherapeutic agents and growth factors showed an average value of 2.7± 3.1%. The percentage of CD34+ in the apheresis products of various patients varied from 0.58 to 1.48. In some cases the cells were reinfused in the patient with good results. Our findings are in agreement with previous studies suggesting that CD34+ stem cells is a heterogeneous population, with each subset having variable degree o commitment to differentiate toward a specific cell lineage.As células progenitoras hematopoéticas são as responsáveis pela produção de todos os elementos do sangue e são as potenciais fontes de células usadas para o tratamento de várias condições patológicas.

O estudo foi realizado mediante uma pesquisa de 3 mil candidatos aptos à doação de sangue no Hemocentro Regional de Lages. Para abordar o tabagismo foi elaborado um questionário que foi inserido na triagem clínica realizada rotineiramente com os candidatos à doação de sangue. Dos 3 mil doadores avaliados na pesquisa, 373 (12,4% eram fumantes, sendo 66,5% do sexo masculino, 77,2% da cor branca, 57,5% com idade entre 18 a 35 anos. O grau de escolaridade foi o ensino fundamental com 42,1%. Em relação ao número de doações anteriores, 43,1% doaram pela 1ª vez, 56,9% dos doadores eram de repetição. O número de cigarros fumados entre um e cinco por dia foi 30,8% e de seis a dez/dia, 33,2%. Os valores de hematócrito e hemoglobina, comparando grupos não fumantes e fumantes, diferiram significativamente uns dos outros. A prevalência de doadores fumantes verificada neste estudo foi considerada pequena, possivelmente não interferindo na qualidade do sangue, pois o percentual que traz problemas em relação a carboxi-hemoglobina está relacionado aos grandes fumantes, sendo a minoria dos doadores estudados. Faz-se necessário conhecer o perfil do doador fumante nos bancos de sangue do País para poder levar o conhecimento e informações através de campanhas educativas e preventivas.Exposure to smoking is a public health problem not very often explored in blood banks.

Full Text Available With the aim of analyzing the effect of high intensity physical activity on the serum values of macro minerals, 19 clinically health adults Thoroughbred horses, males and females from 3 to 5 years of age, were submitted to a galloping in a 2,000 meters sand track. Two blood samples were collected from each animal, one before and another after the high intensity exercise. The results had shown some significative changes (p<0.05 with an increase in the serum values of calcium and magnesium and a decrease in serum and potassium. Meanwhile, there were no alterations (p>0.05 in the concentration of phosphorus and potassium. It is concluded, therefore, that the high intensity exercise leads to transitory and physiologic changes in the serum concentration of macro minerals.Com o objetivo de analisar o efeito da atividade física de alta intensidade sobre os valores séricos dos macrominerais, 19 equinos adultos, com idade entre três e cinco anos, machos e fêmeas, clinicamente saudáveis da raça Puro Sangue Inglês, foram submetidos ao galope de corrida em pistas de areia, na distância de 2000 metros. De cada animal foram colhidas duas amostras de sangue, uma antes e outra após a realização do exercício físico de alta intensidade. A análise dos resultados obtidos demonstrou que houve alterações significativas nos valores séricos do cálcio e magnésio, que apresentaram elevação, e do sódio e cloreto, que apresentaram redução, enquanto não foram verificadas variações significativas nos teores séricos do fósforo e potássio. Conclui-se, portanto, que a atividade física de alta intensidade (galope de corrida altera, transitória e fisiologicamente, a concentração sérica dos macrominerais.

Full Text Available The umbilical cord blood (UCB is an important source of pluripotent stem cells, which motivated researches on ontogeny and transplantation. The morphological characterization of umbilical cord cells is the first step to establish subsequent experiments on these areas. Although some information on humans can be found, no data on UCB is available for bovines. Therefore, this work is the first attempt to conduct an ultrastructural characterization of bovine umbilical cord blood. Blood was collected from the umbilical cord of twenty fetuses by punction of the umbilical vein. Samples were processed for whole leucocytes observation by centrifugation and the buffy coat was collected. Cells were washed and pelleted and prepared according to the standard protocol of the transmission electron microscopy. The presence of cells with morphologic characteristics compatible with the precursors from the erythrocytic, neutrophilic, eosinophilic, basophilic, and lymphocytic lineages was observed. Atypical cells with peculiar morphological features, strongly similar to apoptotic cells, were seen. Bovine neutrophils with three types of cytoplasmic granules were also found in the blood. The ultrastructural characteristics of observed bovine UCB cells where similar to those found in other species, suggesting that bovines could possibly constitute an experimental model for approaches on UCB cells research.O sangue de cordão umbilical (SCU é uma importante fonte de células progenitoras pluripotentes, que motiva pesquisas em ontogenia e transplantes. A caracterização morfológica das células de cordão umbilical é o primeiro passo para se estabelecer experimentos subsequentes nessas áreas. Embora algumas informações sobre SCU em humanos possam ser encontradas, não existe nenhuma informação disponível sobre elas em bovinos. Portanto, este trabalho é a primeira tentativa de se conduzir uma caracterização ultra-estrutural do sangue de cordão umbilical

Full Text Available La ciencia del bienestar animal permite dar al animal las condiciones idóneas para mejorar su calidad de vida, esta ciencia evalúa el estado de un individuo frente a los intentos de afrontar los cambios del ambiente, basándose en el estado físico, fisiológico y mental de cada animal. En los sistemas de producción bovinos se desarrollan actividades que conllevan cambio de ambiente para los animales y el aumento de la interacción humano – animal, lo que ocasiona una alteración de las condiciones físicas, mentales y fisiológicas del animal, donde la actividad que genera mayores alteraciones en los bovinos es el transporte, especialmente el embarque y el desembarque, debido a las caídas, golpes, resbalones y cambios de ambiente que se reflejan en la presencia de hematomas, fracturas, contusiones y aumento de los niveles de estrés. Lo cual genera  lesiones de la canal que son el resultado de un impacto de los tejidos blandos acompañado de la ruptura de vasos sanguíneos y alteración de las propiedades organolépticas de la carne, donde el parámetro más importante es el pH, ya que si éste aumenta por los elevados niveles de estrés ante-mortem, favorece la proliferación de microorganismos, reduciendo así la vida útil del producto y convirtiendo el producto en un riesgo para la salud pública. Es por ello que el presente artículo busca identificar y analizar la importancia de implementar el bienestar animal en las actividades de embarque y desembarque en los sistemas de producción bovinos.

Descrição dos casos: Dois pacientes imunocompetentes foram clinicamente diagnosticados com toxoplasmose ocular aguda. Rotineiramente, a avaliação clínica foi feita por fundoscopia com o uso de oftalmoscópio binocular indireto, retinografia colorida, angiografia fluorescente e tomografia de coerência óptica espectral. A sorologia foi realizada por ensaio imunoenzimático (ELISA e confirmada por ensaio imunoenzimático fluorescente ELFA (IgG, IgM. O diagnóstico molecular foi realizado por PCR em sangue periférico usando o gene B1 de Toxoplasma gondii como marcador. O paciente mais jovem era do sexo masculino, apresentava lesão prévia no olho direito, queixa de baixa acuidade visual no olho esquerdo e estava sob tratamento. O paciente mais velho era do sexo masculino, apresentava descolamento de retina e súbita diminuição de visão no olho direito. A fundoscopia revelou cicatriz coriorretiniana no olho esquerdo. Ambos os pacientes tinham IgG reagente, IgM não reagente e PCR positivo em sangue periférico. Novas amostras de sangue foram coletadas para monitoramento sorológico e molecular e a PCR permaneceu positiva em ambos os casos. Seis semanas após o início do tratamento com sulfadiazina e pirimetamina oral, os resultados do PCR tornaram-se negativos. Conclusões: Os resultados mostram que antígenos de T. gondii podem ser encontrados em sangue periférico durante as reativações oculares e que a PCR parece ser uma boa ferramenta para o acompanhamento de pacientes com toxoplasmose ocular

O Ministério da Saúde determina a realização de testes para sífilis, hepatite B e C, HIV, doença de Chagas, HTLV I/II e malária nas áreas endêmicas, em todas as unidades de sangue coletadas no Brasil. A amostra do doador deve ficar armazenada por um período mínimo de seis meses. Com relação aos receptores de sangue, o Ministério determina a realização de testes imuno-hematológicos pré-transfusionais tais como classificação ABO/Rh, pesquisa de anticorpos irregulares e testes de compatibilidade. Nesse caso, a amostra do receptor deve ficar armazenada por um período de dez dias. Considerando que algumas patologias testadas, quando não detectadas no doador, podem ser transmitidas e cursar durante décadas sem apresentar sintomas, um estudo de provas entre receptores e seus respectivos doadores fica comprometido. Um recente estudo no Brasil, envolvendo receptores sem passado transfusional, eventual e politransfundidos mostrou uma importante prevalência de patologias que podem ser transmitidas pelo sangue. O estudo revelou também que uma elevada percentagem dos receptores que apresentaram reatividade não tinha conhecimento prévio à transfusão do seu estado sorológico.

Para comprovar a efetividade do método proposto realizou-se contagem mecânica do sangue, bem como do produto final. RESULTADO: Obteve-se uma concentração média de plaquetas no plasma rico em plaquetas 687% maior que a contagem inicial observada no sangue venoso periférico. Para as variáveis: contagem inicial de plaquetas, contagem de plaquetas no plasma rico em plaquetas e enriquecimento, foram obtidos os limites de 95% de confiança para suas médias, sendo que, no que se refere ao percentual de enriquecimento, existe 95% de chance de que o intervalo de (530-844 contenha a média real de enriquecimento de plaquetas. CONCLUSÃO: O método simplificado utilizado permite a obtenção de plasma rico em plaquetas adequado permitindo seu uso em estudos dos fatores de crescimento nos mecanismos de reparação tecidual.BACKGROUND: Multiple uncertainties still exist about the action of the growth factors and the platelet-rich plasma on the mechanism of repair. AIM: To obtain the platelet-rich plasma in rabbits through a simplified and suitable method, creating an experimental model. METHODS: Twenty-five female New Zealand rabbits without previous diseases were used. Fifteen mL of blood of each rabbit was collected and 10 mL of the collected blood were twice centrifugated. To check the effectiveness of the proposed method

Full Text Available Uma doaç��o de aproximadamente 475mL de sangue depleta em média 242 ± 17 mg de ferro do doador, o que pode ter conseqüências variáveis em suas reservas e na sua saúde. Tivemos por objetivo avaliar se doadores de sangue do Hemocentro do Amazonas - Hemoam desenvolvem sideropenia sem anemia após doações consecutivas. A ferritina sérica foi medida em 528 doadores de sangue, do sexo masculino, com idade entre 18 a 61 anos, divididos em 313 doadores de repetição, com 4 ou mais doações regulares, e 215 primodoadores, que compareceram ao Hemocentro do Amazonas no período de setembro de 2001 a junho de 2002. Depleção do depósito de ferro, definida por níveis de ferritina menores de 20 ng/L, foi encontrada em 7,4% [16/215] dos primodoadores e em 48,6% [152/313] dos doadores de repetição. Utilizando-se de um critério mais rigoroso, como valores de ferritina A blood donation of 475 mL could deplete 242 ± 17 mg of iron from blood donors. The objective of this report is to evaluate if blood donors could develop sideropenia without anemia after several donations. Serum levels of ferritin were measured in 528 male blood donors, with ages ranging from 18 to 61 years old. A total of 313 of them had made 4 or more donations and 215 of them were first time donors. They donated blood in the Hemocentro do Amazonas - Hemoam, from September 2001 to June 2002. Deletion of iron stores characterized by serum ferritin levels of less than 20 ng/L was found in 7.4% (16/215 of first time donors, and in 48.6% (152/313 of multiple donors. With more stringent criteria of ferritin values less than 12 ng/L, 3.7% (8/215 of first-time donors as opposed to 24.9% (78/313 of multiple donors showed severe depletions. We concluded that multiple donors, after more than 5 repeated donations, are at risk of depleted iron and ferritin levels. It is important to implant protocols of iron supplementation for these donors to avoid damage to their health and

Full Text Available É registrado, presumivelmente pela primeira vez na literatura, o aumento da aminacidúria em casos de leucodistrofia metacromática. Mediante cromatografia circular e bidimensional foram estudados os aminácidos livres na urina, sangue, saliva e líquido cefalorraqueano de dois casos familiais de leucodistrofia metacromática. No sangue foi verificado aumento da concentração de cistina, ácido as-pártico, glicina, ácido glutâmico, alanina, prolina, tirosina e fenilalanina. Na urina encontravam-se elevados o ácido aspártico, cistina, alanina, prolina, tirosina e fenilalanina. Na saliva foi notado aumento do ácido a-y-diaminobutírico, ácido glutâmico, alanina e prolina. No líquido cefalorraqueano o ácido aspártico, alanina, prolina e fenilalanina encontravam-se em maiores concentrações. Além disso, estavam presentes 6 aminácidos não identificados. Um dêles desintegrava-se em três componentes e uma destas frações comportava-se como um polipeptídeo, provàvelmente identificável a uma substância composta de ácido glutâmico, glicina e ácido aspártico. Esta substância poderia integrar um complexo polipéptido-lipídico resultante de um dismetabolismo lipídico, já conhecido nas leucodistrofias, associado a um distúrbio do metabolismo protêico, agora relatado. Os resultados são comparados com os dados referidos na literatura relativa às concentrações de aminácidos no líquido cefalorraqueano e urina de algumas afecções nervosas de caráter desmielinizante. No líquido cefalorraqueano o perfil da leucodistrofia metacromática se assemelha aos anteriormente encontrados na moléstia de Niemann-Pick, na degeneração ce-rebromacular e na "esclerose difusa". Na urina as alterações se aproximam das que ocorrem na moléstia de Hartnup.

2014-10-01

Full Text Available El entrenamiento de fuerza orientado a aumentar la masa muscular se ha convertido en un objetivo común en programas de entrenamiento tanto en deportistas de alto rendimiento como en personas que realizan programas de actividad física con objetivo de mejorar su salud o calidad de vida. Generalmente, el trabajo de fuerza orientado hacia la hipertrofia muscular se ha asociado con la utilización de altas cargas de trabajo (70-85% de 1 RM. Actualmente, se ha propuesto que el entrenamiento de fuerza con cargas de tan solo el 20% de 1 RM realizadas en condiciones de restricción del flujo sanguíneo podría provocar incrementos en los niveles de fuerza y masa muscular similares a los observados al ejercitarse con cargas altas. Dado que ciertos colectivos podrían beneficiarse del empleo de bajas cargas en sus programas de entrenamiento orientados a incrementar la masa muscular, el objetivo del presente trabajo de revisión bibliográfica ha sido el de revisar en la literatura las evidencias que existen en torno a la efectividad del entrenamiento con restricción del flujo sanguíneo a la hora de provocar hipertrofia muscular. Abstract Strength training focuses on increasing muscle mass has become in a frequent target in training programs in both elite athletes and people performing physical activity programs to improve their health or quality of life. Generally, the resistance training oriented muscle hypertrophy has been associated with the use of high workloads (70-85% of 1RM. Currently, it has been proposed that the resistance training with loads of only 20% 1RM under conditions of restricted blood flow can induce increases in strength levels similar to resistance training with high intensities. Because certain groups could benefit from the use of low loads in their strength training programs designed to increase muscle mass, the objective of the present study was to review the literature on the existing evidence about the effectiveness of blood

Full Text Available INTRODUÇÃO: A participação dos atletas em sessões de exercício intenso e prolongado pode fazer declinar o número circulante e a capacidade funcional dos leucócitos. Por outro lado, o consumo de uma solução carboidratada pode atenuar os efeitos imunossupressivos do exercício. OBJETIVO: Verificar os efeitos do exercício aeróbio e anaeróbio, além da suplementação carboidratada sobre as concentrações sanguíneas da contagem total e diferencial de leucócitos, hemoglobina e glicose sérica de ratos Wistar. MÉTODOS: Sessenta e nove Ratos machos Wistar (60 dias foram divididos em seis grupos: sedentários não suplementados (n = 12 e suplementados (n = 12; treinados em estado estável máximo de lactato (EEML não suplementados (n = 11 e suplementados (n = 11; treinados em alta intensidade não suplementados (n = 12 e suplementados (n = 11. O protocolo de treinamento consistiu de oito semanas de natação em padrão contínuo em EEML (60 min.dia-1 ou intermitente (dois períodos de 30 minutos, com intervalo de 10 minutos, com sobrecargas correspondentes a 5% e 10% do peso corporal, respectivamente. Durante 37 dias os animais foram suplementados com uma dose diária de 0,48 g.kg-1 de maltodextrina dissolvida em água ou receberam água pura. RESULTADOS: Não houve efeito da suplementação carboidratada e dos dois tipos de treinamento nas concentrações de leucócitos sanguíneos. O exercício anaeróbio (p = 0,04 e o uso da maltodextrina (p = 0,003 proporcionaram elevações nas concentrações de hemoglobinas sanguíneas, enquanto o exercício aeróbio ocasionou aumento na concentração da glicose sérica (p < 0,02. CONCLUSÃO: Os diferentes tipos de exercícios não estiveram envolvidos com leucopenia, hipoglicemia ou anemia que poderiam levar a fadiga muscular precoce e queda do desempenho.

Full Text Available Neste artigo teve-se por objetivo refletir sobre o caráter simbólico da circulação do sangue e a exploração de informações genéticas de povos indígenas. Para esse fim, compararam-se dois casos, colocando em jogo a coleta de sangue irregular. O primeiro, a respeito do povo Yanomami, foi objeto de um acordo internacional, realizado entre o Ministério Público Federal e universidades norte-americanas, o que resultou no repatriamento das amostras de sangue ao Brasil. O segundo, a respeito do povo Karitiana, deu lugar a uma ação civil pública, proposta pelo Ministério Público Federal, que resultou em uma indenização ordenada pelo Tribunal Regional Federal da 1ª Região por dano moral sofrido pelos índios. Os dois casos convidam a examinar três questões sensíveis: a vulnerabilidade dos povos indígenas em face ao princípio do consentimento livre e esclarecido, exigido para a coleta do material genético; a insuficiência do princípio da gratuidade e o desafio da repartição de benefícios, quando se trata de explorar as informações genéticas humanas; e as recompensas comparadas da indenização financeira e da restituição das amostras em face às aspirações igualitárias dos povos indígenas em questão. Palavras-chave: Coleta de sangue. Consentimento livre e esclarecido. Contrato de repartição de benefícios. Dano moral. Povos indígenas.

Lâminas com microfilárias de Mansonella ozzardi foram montadas e fotografadas pelos diferentes métodos de diagnósticos. O método da gota espessa de sangue é o mais confiável, pois permite visualizar com nitidez o espaço cefálico e caudal, disposição dos núcleos caudais e formato da cauda, que são características morfológicas que diferenciam as espécies de microfilárias sanguíneas que ocorrem no Amazonas.In this work, the visual diagnostic methods for human filarias in the blood are evaluated. The thick blood film method is more faithful to identify the microfilariae species if compared to policarbonate membrane filtration and Knott methods, especially in areas where more than one species occur, as in Amazon basin. Slides with Mansonella ozzardi microfilariae were mounted and photographed by different diagnosis methods. The thick blood film method is much easier to see the diagnostic morphological characters as cephalic and caudal space, pattern of nucleation of the tail and tail shape that can separate the blood Amazonian microfilariae species.

Full Text Available A ocorrência de hemagregarinas no sangue dos sapos que examinamos (Bufo crucifer, B. marinus e Melanophryniscus moreirae revelou-se extremamente rara; apenas um exemplar de B. crucifer procedente de Manguinhos (Rio de Janeiro, Guanabara apresentou-se parasitado. As formas sanguíneas encontradas eram intra-eritrocitárias, medindo em média 10,8/ 3,6µ; não as identificamos como trofozoítos ou gametócitos e discutimos este fato. As hemácias parasitadas tinham dimensões normais, porém podiam ter o núcleo deslocado. Supomos ser esta a primeira referência a hemogregarinas neste hospedeiro. Não encontramos identidade entre as formas que descrevemos e aquelas referidas em outras espécies de sapos; fornecemos uma lista das hemogregarinas achadas nestes hospedeiros. Denominamos provisoriamente os parasitos que encontramos Haemogregarina "sensu lato", até que novos dados sobre seu ciclo evolutivo sejam conhecidos.The occurrence of hemogregarines in the blood of Brazilian toads that we have examined (Bufo crucifer, B. Marinus and Melanophryniscus moreirae has displayed very scarce; only one specimen of B. crucifer from Manguinhos (Rio de Janeiro, Guanabara was infected. The blood forms that we found were intraerythrocytic, averaging 10,8 by 3,6µ; we did not differenciate them as thophozoites or as gametocytes and we discuss this fact. The infected erythrocytes were not hypertrophied and their nucleus was normal and sometimes displaced. We think that it is the first reference to hemogregarines in this host. We did not evidence identity among the forms that we described and those reported in other species of toads; we give a list of hemogregarines found in those hosts. We provisorily named the parasites that we found Haemogregarina "sensu lato", until new data about their life cycle become known.

Full Text Available PURPOSE: An experimental study was performed to investigate the use of protein carbonyl group as a specific biological marker for oxidative stress in a rat model of intestinal ischaemia-reperfusion. METHODS: Twenty four male Wistar rats were randomly distributed into three groups with eight animals each: Group 1 - Control group; Group 2 - Sham; Group 3 - Intestinal ischaemia by clamping ileal branches of the superior mesenteric artery for one hour, followed by another hour of reperfusion. Blood samples were taken in order to analyze the protein carbonyl level by Slot blotting assay. RESULTS: In group 3 a significant increase of protein carbonyl level was observed if compared to the homogenous levels of groups 1 and 2. CONCLUSION: From the results it may be concluded that the protein carbonylation may be used as a specific marker for measuring oxidative stress in rat intestinal reperfusion model.OBJETIVO: Realizou-se um estudo experimental com a finalidade de investigar o uso da proteína carbonilada como um marcador biológico específico do estresse oxidativo em um modelo de isquemia e reperfusão intestinal, em ratos.

Define um coeficiente hemoglobínico como a relação entre a concentração de oxiemoglobina e o total de pigmentos do LCR e um índice hemoglobina-bilirrubina como a relação entre as concentrações de oxiemoglobina e bilirrubina. Depois do tratamento estatístico, chega à conclusão de que ambos permitem estimar o tempo transcorrido desde o surto hemorrágico subaracnóideo e a colheita de LCR. São apresentadas sugestões quanto à aplicabilidade prática destes indicadores em Neurologia e Medicina Preventiva.Hemorrhagic cerebro-vascular accidents were simulated in dogs by injecting their own blood in the subarachnoidal space. Gathering daily samples of cerebrospinal fluid during 14 days the evolution of the concentrations of oxyhemoglobin and bilirubin using the spectrosphotometric method was studied. The author defines hemoglobin coefficient as being the relatinship between the oxyhemoglobin concentration and the sum of the cerebrospinal fluid pigments and the hemoglobin-bilirubin index as the relationship between the oxyhemoglobin and the bilirubin concentration. After statistical treatment the author concludes that both permit to calculate the time span between the subarachnoidal hemorrhage and the examination of the cerebrospinal fluid. Some suggestions on the practical applicability of these indexes in Clinical Neurology and Preventive Medicine are discussed.

Após o parto, amostras de colostro da primeira ordenha foram colhidas e, posteriormente, submetidas à imunodifusão radial simples para determinações dos níveis de imunoglobulinas G (IgG. Os resultados obtidos permitiram concluir que as concentrações de IgG não são influenciadas pelos graus de sangue estudados e seus valores médios (145,94mg/m são muito superiores aos relatados para animais de raças taurinas puras. Por esse motivo, não se justifica o emprego de métodos artificiais de fornecimento do colostro em se tratando de mestiços HZ. Ademais, o nível elevado de IgG observado no colostro sugere que a adoção da prática da mamada natural assistida seja adequada para assegurar que, na maioria das vezes, os neonatos não venham a apresentar falhas de transferência de imunidade passiva.Eighty-eight healthy crossbred holstein-zebu (HZ dairy cows were distributed in four groups as follow: Group 1 = less than 70% HZ (19 cows; Group 2 = 75% HZ animals, corresponding to ¾ HZ (46 cows; Group 3 = crossbred animals between 80 to 90% HZ, corresponding to 13/16 HZ and 7/8 HZ (11 cows; Group 4 = cows more than 90% HZ (12 animals. After birth, colostrum samples were obtained from each cow and than were analyzed for immunoglobulin G (IgG concentration by single radial immunodifusion assay. IgG colostral concentrations were not influenced by group of crossbred HZ and its mean concentration (145.97mg/m were higher than that related for purebreds Bos

Full Text Available A frequente utilização de sangue de cordão umbilical - SCU como fonte de células- tronco hematopoéticas - CTH, tanto em crianças, como em adultos, que não dispõem de doador na família, tem levado ao estabelecimento da padronização de critérios em sua seleção, objetivando a obtenção de melhores resultados. A escolha da unidade de SCU deve basear-se no número total de células nucleadas e no número de diferenças de antígenos leucocitários humanos (HLA. Diante de uma unidade com celularidade mínima, deve-se considerar a possibilidade da utilização de duplo cordão. Frente a mais de uma unidade com características semelhantes, a realização da contagem de células CD34 e da compatibilidade ABO, assim como a qualidade e a rapidez para obtenção da unidade, podem definir a escolha.The frequent use of umbilical cord blood as the source of hematopoietic stem cells, both in children and adults who do not have related donors, has led to the establishment of a better standardization of selection criteria aiming at improving the results. The choice of the umbilical cord blood unit should be based on the total number of nucleated cells and the number of differences in the human leukocyte antigen (HLA system. When a unit has minimal cellularity, the use of a double cord blood transplant should be considered. When two or more units have similar characteristics, the choice may be determined by the CD34 count, ABO compatibility and the quality and speed to obtain the unit.

Full Text Available Os membros da equipe de enfermagem submetem-se muitas vezes a agressões posturais quer devido a própria exigência da atividade, quer pela utilização de postura corporal inadequada durante a execução das mesmas. O presente estudo tem por objetivo averiguar o tipo, duração e freqüência das posturas adotadas pelos membros da equipe de enfermagem durante a execução das técnicas de colheita de sangue, administração de medicação endovenosa e soroterapia. Através da observação direta foram registradas 10 atividades correspondentes a cada uma das técnicas mencionadas, realizadas na assistência a pacientes de uma unidade de internação de um Hospital Universitário. Os resultados evidenciam que a atividade de colheita de sangue foi efetuada na posição de pé-inclinado (50,35%, seguida pela posição de pé-ereto (49,64%. A administração de medicação endovenosa foi executada com adoção das posturas de pé-ereto (51,09% em especial com braço em extensão frontal, de pé-inclinado (45,74% e sentado (3,15%. A técnica de soroterapia foi executada com adoção da posição de pé-ereto (86,88%, em especial corn braços em extensão frontal e de pé-inclinado (13,11%. A adoção freqüente da postura inclinada indica que o pessoal de enfermagem vem tornando possível a ocorrência de agressões na coluna vertebral desnecessárias, principalmente devido a má utilização da mecânica corporal. Sugere-se maior atenção para esses aspectos principalmente nos cursos de enfermagem.

Verificou-se pouca informação e informações errôneas sobre a doação. A escola foi a fonte de informação menos citada. A maioria dos entrevistados tanto na entrevista, como no dilema, justificou a doação de sangue como um ato solidário, permitindo supor que valores como generosidade podem ser adquiridos na fase pré-operatória. Discute-se o papel da escola nos programas de Educação em Saúde voltados a comportamentos que serão emitidos a longo prazo e que beneficiam a coletividade.This study investigated children's values and perceptions of blood donation. A hundred forty-five students (preschool, second- and fourth-graders aged 6, 8 and 10 years old answered Piagetian tests. They were also interviewed on blood donation and faced a moral dilemma. Lack of information and misinformation were observed. The school was the least frequently cited information source. Findings showed that the participants justified blood donation as an act of solidarity. It indicates that children have a conception of values since the preoperational stage of cognitive development. It is also presented a discussion on the role of schools in Health Care Education, particularly targeting specific behaviors which will be expressed in the long term such as blood donation.

Full Text Available Os constituintes do perfil lipídico compõem o sangue e são importantes marcadores bioquímicos de doenças cardiovasculares, que é reconhecida como grande causa de morbidade e mortalidade. Para um diagnóstico mais amplo das possíveis alterações do perfil lipídico se apresenta o método da espectroscopia no infravermelho (FTIR que consiste de uma técnica analítica que envolve a identificação de misturas complexas. Este estudo tem como objetivo avaliar a aplicação da espectroscopia de infravermelho na obtenção de dados do perfil lipídico de atletas corredores. Trata-se de um estudo analítico observacional comparativo, tendo como método de referência os ensaios enzimáticos baseados na reação de Trinder, comparados à espectroscopia no infravermelho por reflectância difusa com Transformada de Fourier (DRIFTS, com auxílio das ferramentas quimiométricas de análise exploratória por agrupamento hierárquico (HCA e análise preditiva por mínimos quadrados parciais (PLS para previsão destes marcadores bioquímicos. Foram sujeitos 14 atletas da equipe de Atletismo da UNISC, de 18 a 30 anos, de ambos os sexos, avaliados em repouso e após o teste ergoespirométrico de Bruce. Os resultados apontam que, na avaliação de atletas, a técnica de infravermelho (DRIFTS juntamente com o PLS, foi adequada para a construção de modelos de calibração e na definição da correlação entre testes bioquímicos padrões no perfil lipídico e na determinação pelo infravermelho. Nessa perspectiva, considera-se possível a utilização da FTIR na obtenção de dados que determina o perfil lipídico em amostras de sangue total em atletas.

Animal welfare: an animal science approach.

Increasing world population and demand for animal-derived protein puts pressure on animal production to meet this demand. For this purpose animal breeding efforts were conducted to obtain the maximum yield that the genetic makeup of the animals permits. Under the influence of economics which is the driving force behind animal production, animal farming became more concentrated and controlled which resulted in rearing animals under confinement. Since more attention was given on economics and yield per animal, animal welfare and behavior were neglected. Animal welfare which can be defined as providing environmental conditions in which animals can display all their natural behaviors in nature started gaining importance in recent years. This does not necessarily mean that animals provided with good management practices would have better welfare conditions as some animals may be distressed even though they are in good environmental conditions. Consumers are willing to pay more for welfare-friendly products (e.g.: free range vs caged egg) and this will change the animal production practices in the future. Thus animal scientists will have to adapt themselves for the changing animal welfare rules and regulations that differ for farm animal species and countries. In this review paper, animal welfare is discussed from an animal science standpoint. Crown Copyright © 2013. Published by Elsevier Ltd. All rights reserved.

Full Text Available Leishmaniasis is a zoonotic disease that affects 12 million people worldwide. Several mammalian species can serve as a reservoir for this disease. Dogs are the main reservoir for visceral leishmaniasis in urban areas, which has become a serious public health concern in Brazil. The aim of this study was to evaluate the presence of Leishmania spp. in captive wild animals from Ilha Solteira, São Paulo, Brazil. Blood and various tissues samples were collected from animals of five different species: Speothos venaticus, Chrysocyon brachyurus, Cerdocyon thous, Pseudalopex vetulus, and Procyon cancrivorus. Antibodies against Leishmania spp. were detected in three wild canids by indirect fluorescent antibody test (IFAT and enzyme-linked immunosorbent assay (ELISA. PCR analyses of blood and bone marrow from all animals were negative, but Leishmania DNA was found in the tissues and skin of seropositive animals. Positive PCR samples were also positive for Leishmania donovani complex. Analysis of sequenced PCR products showed similarities with different regions of Leishmania (Leishmania infantum and Leishmania (Leishmania chagasi kinetoplastids. Measures to control visceral leishmaniasis in wild animals kept in Brazilian zoos should be established, as no disease control programs are currently available.Leishmaniose é uma doença zoonótica que afeta cerca de 12 milhões de pessoas no mundo todo.

A utilização de equipamentos automatizados no processamento de hemoculturas gerou uma alternativa para diagnóstico de ICSRC por meio da análise da diferença de tempo de positividade (DTP entre hemoculturas pareadas (coletadas simultaneamente de sangue periférico e sangue de cateter. Um diagnóstico acurado e rápido dessas infecções pode otimizar as condutas clínicas e terapêuticas, poupando a retirada precoce dos cateteres. OBJETIVOS: Avaliar na rotina a DTP como ferramenta auxiliar no diagnóstico de ICSRC e determinar os principais microrganismos isolados. MÉTODOS: Foram avaliadas retrospectivamente hemoculturas coletadas no complexo do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (HC/FMUSP de maio a agosto de 2008. Somente amostras que apresentaram DTP maior que 120 minutos foram consideradas possíveis ICSRCs pelo critério laboratorial. RESULTADOS: A seção processou 11.017 hemoculturas aeróbias durante o período de estudo; somente 5% foram coletadas de forma pareada. Destas, 148 (28% foram positivas, sendo 9% com crescimento somente em sangue periférico, 41% somente em sangue de cateter e 50% em ambas as amostras com 88% de homologia de microrganismos identificados. A DTP apresentou valores acima de 120 minutos em 50% dos casos e os microrganismos mais isolados foram Staphylococcus aureus (22%, Candida spp. (18%, Klebsiella spp. (7% e Enterobacter spp. (7%.

Hundreds of thousands of laboratory animals are being used every year for scientific experiments held in Israel, mostly mice, rats, rabbits, guinea pigs, and a few sheep, cattle, pigs, cats, dogs, and even a few dozen monkeys. In addition to the animals sacrificed to promote scientific research, millions of animals slain every year for other purposes such as meat and fine leather fashion industries. While opening a front against all is an impossible and perhaps an unjustified task, the state of Israel enacted the Animal Welfare (Animal Experimentation) Law (1994). The law aims to regulate scientific animal experiments and to find the appropriate balance between the need to continue to perform animal experiments for the advancement of research and medicine, and at the same time to avoid unnecessary trials and minimize animal suffering. Among other issues the law deals with the phylogenetic scale according to which experimental animals should be selected, experiments for teaching and practicing, and experiments for the cosmetic industry. This article discusses bioethics considerations in animal experiments as well as the criticism on the scientific validity of such experiments. It further deals with the vitality of animal studies and the moral and legal obligation to prevent suffering from laboratory animals.

Full Text Available A descoberta e a aplicação clínica de biomarcadores para desordens mentais são confrontadas com muitos desafios. Em geral, os atuais métodos de descoberta e validação de biomarcadores não produziram os resultados que foram inicialmente aguardados depois da finalização do Projeto Genoma Humano. Isso se deve principalmente à falta de processos padronizados conectando a descoberta de marcadores com tecnologias para a validação e a tradução para uma plataforma que ofereça precisão e fácil uso em clínica. Como consequência, a maior parte dos psiquiatras e praticantes em geral são relutantes em aceitar que testes de biomarcadores pode suplementar ou substituir os métodos de diagnóstico utilizados baseados em entrevista. Apesar disso, agências regulatórias concordam agora que melhoras nos correntes métodos são essenciais. Além disso, essas agências estipularam que biomarcadores são importantes para o desenvolvimento de futuras drogas e iniciaram esforços no sentido de modernizar métodos e técnicas para suportar esses esforços. Aqui revisamos os desafios encontrados por essa tentativa do ponto de vista de psiquiatras, praticantes em geral, agências reguladoras e cientistas de biomarcadores. Também descrevemos o desenvolvimento de um novo teste sanguíneo molecular para esquizofrenia como um primeiro passo a esse objetivo.

Animal rights and animal experimentation. Implications for physicians.

Science.gov (United States)

Gelpi, A. P.

1991-01-01

Practicing physicians are just becoming aware of the animal rights movement, which during the 1980s spawned numerous acts of violence against research facilities throughout the United States. The animal rightists are challenging physicians to show moral justification for the human exploitation of nature and the world of subhuman species. They have aroused public interest in animal welfare, sparked protective legislation for experimental animals, and indirectly encouraged the creation of committees to oversee the conduct of animal experimentation and the conditions of animal confinement. This controversy has necessitated a closer look at the questions of animal experimentation and animal rights against the backdrop of human experimentation and human rights. Physicians and specialists in animal care seek to alleviate suffering and anxiety, and, as moderates, they may be able to bring both sides of the animal rights controversy together in a spirit of mutual tolerance and in the common cause of promoting both human and animal welfare.

ADVANCES IN ANIMAL WELFARE FOR FREE-LIVING ANIMALS.

Science.gov (United States)

2016-04-01

Over several decades, animal welfare has grown into its own free-standing field of scientific study, from its early beginnings in laboratory animal research to eventually include exhibited animals and farm animals. While it has always been present to some degree, consideration of animal welfare for free-ranging animals has lagged behind, developing as a field of study in the last 20 yr or so. Part of that increase was that animal welfare legislation was finally applied to studies being done on free-ranging animals. But it is the appreciation by the biologists and veterinarians working on wild animals, in which the quality of their results is largely controlled by the quality of the animals they use in their studies, which has resulted in increased attention to the well-being or welfare of the animals that they use. Other important influences driving the recognition of wildlife welfare have been changes in the public's expectations of how wild animals are dealt with, a shift in focus of wildlife professionals from managing animals that can be hunted or angled to include nongame species, the decrease in participation in hunting and fishing by members of the public, and the entry of large numbers of women into fish and wildlife agencies and departments and into veterinary medicine. Technical improvements have allowed the safe capture and handling of large or dangerous animals as immobilization drugs and equipment have been developed. The increasing use of sedating drugs allows for handling of animals with reduced stress and other impacts. A number of topics, such as toe-clipping, branding, defining which taxa can or cannot feel pain, catch-and-release fishing, and more, remain controversial within wildlife science. How we treat the wild animals that we deal with defines who we are as wildlife professionals, and animal welfare concerns and techniques for free-ranging animals will continue to develop and evolve.

We compared the results of whole blood concentrations of CyA in 50 blood samples simultaneously evaluated by the fluorescent polarization immune assay (TDx and the enzymatic competitive immune assay (EMIT 2000. There was a strong correlation between both kits for any range of CyA blood concentration (R=0.99, pA avaliação da concentração sanguínea de ciclosporina A (CyA é necessária em transplantes de órgãos sólidos para obter-se máxima imunosupressão e mínimos efeitos colaterais. Nós comparamos os resultados da concentração de CyA em 50 amostras sanguíneas analisadas pelos métodos dos imuno-ensaios de fluorescência polarizada (TDx e enzimático competitivo (EMIT 2000. Houve uma forte correlação entre ambos métodos para qualquer faixa de concentração de CyA (R=0.99, p<0.001. Os coeficientes de variação intra e interensaio foram menores que 4% para ambos os métodos. O custo para cada análise de CyA foi 50% menor para o EMIT em comparação com o TDx. Concluímos que a metodologia EMIT é tão acurada quanto a de TDx para dosar CyA em amostras sanguíneas. Além disso, a metodologia EMIT é mais prática para ser realizada e mais barata, sendo ainda possível adotá-la para dosagens de CyA em vários horários de um mesmo dia.

The radionuclides of most concern with respect to contamination of animals after a nuclear accident are radioiodine, radiocaesium and radiostrontium (ICRP 30, 1979). Of the other significant anthropogenic radionuclides likely to be released in most accidents, only small proportions of that ingested will be absorbed in an animals gut, and the main animal products, milk and meat, will not normally be contaminated to a significant extent. Animal products will mostly be contaminated as a result of ingestion of contaminated feed and possibly, but to a much lesser extent, from inhalation (for radioiodine only). Direct external contamination of animals is of little or no consequence in human food production. Radioiodine and radiostrontium are important with respect to contamination of milk; radiocaesium contaminates both milk and meat. The physical and chemical form of a radionuclide can influence its absorption in the animal gut. For example, following the Chernobyl accident radiocaesium incorporated into vegetation by root uptake was more readily absorbed than that associated with the original deposit. The transfer of radiocaesium and radiostrontium to animals will be presented both as transfer coefficients and aggregated transfer coefficients. For most animal meat products, only radiocaesium is important as other radionuclides do not significantly contaminate muscle. Farm animal products are the most important foodstuff determining radiocaesium intake by the average consumer in the Nordic countries. The major potential source of radioiodine and radiostrontium to humans is milk and milk products. Of the different species, the smaller animals have the highest transfer of radiocaesium from fodder to meat and milk. (EG). 68 refs.

Knowledge of the Animal Welfare Act and Animal Welfare Regulations Influences Attitudes toward Animal Research

Science.gov (United States)

2015-01-01

Recent public-opinion polls indicate that Americans have shown a decline in support for animal experimentation, and several reports suggest a relationship between people's knowledge of animal welfare regulations and their attitudes toward animal research. Therefore, this study was designed to assess respondent's knowledge of several provisions in the Animal Welfare Act (AWA) and Animal Welfare Regulations (AWR), and determine whether exposure to elements of this legislation would influence an individual's attitudes toward the use of animals in research. A survey was used to assess knowledge of animal research regulations and attitudes toward animal research from a sample of individuals recruited through Amazon's Mechanical Turk crowdsourcing marketplace. Results from study 1 confirmed the hypothesis that respondents had little knowledge of various federal regulations that govern animal research activities. Data from study 2 revealed that exposure to elements of the AWA and AWR influenced participants’ attitudes toward the use of animals in research. These results suggest that providing information to the general public about the AWA and AWR that protect laboratory animals from abuse and neglect may help alleviate concerns about using animals in research settings.

This article presents the ethical issues in animal research using a combined approach of ethical theory and analysis of scientific findings with bearing on the ethical analysis. The article opens with a general discussion of the moral acceptability of animal use in research. The use of animals...... in research is analyzed from the viewpoint of three distinct ethical approaches: contractarianism, utilitarianism, and animal rights view. On a contractarian view, research on animals is only an ethical issue to the extent that other humans as parties to the social contract care about how research animals...... are faring. From the utilitarian perspective, the use of sentient animals in research that may harm them is an ethical issue, but harm done to animals can be balanced by benefit generated for humans and other animals. The animal rights view, when thoroughgoing, is abolitionist as regards the use of animals...

Resumo. Nos flebotomíneos (Diptera: Psychodidae o hábito pela hematofagia é responsável pela indução de vários processos fisiológicos também na transmissão de Leishmania Ross. O presente estudo compara o sangue de ave, de mamífero e com infecção por Leishmania amazonensis Lainson & Shaw sobre o potencial biológico de Lutzomyia migonei (França e de Lutzomyia ovallesi Ortiz. Foram utilizadas fêmeas das duas espécies alimentadas artificialmente com sangue de hamster (Mesocricetus auratus Waterhouse e frango (Gallus gallus Linnaeus, infectados com L. amazonensis. Os grupos controle foram alimentados somente com sangue, sem parasitas. Foram determinados o grau de repasto sanguíneo, o tempo de digestão, o padrão de diurese, o tempo de oviposição, a sobrevivencia a oviposição e a fecundidade. A espécie L. migonei quando alimentada com sangue de hamster e frango apresentaram maior fecundidade do que as fêmeas de L. ovallesi, a maior fecundidade foi com sangue de frango. A presença de Leishmania no sangue de frango ou sangue de hamster diminuiu significativamente o seu consumo, o que resultou na diminuição da sobrevida das fêmeas após a oviposição em L. migonei alimentados com sangue de frango e não com sangue de hamsters. Entretanto, não afetar a quantidade de sangue e a sobrevivência de oviposição de L. ovallesi. A infecção com L. amazonensis causo um aumento no número de ovos retidos e diminuiu o número de ovos postos por L. migonei e L. ovallesi, especialmente com sangue de frango e também reduz o tempo de digestão do sangue em ambas as espécies com sangue de frango, mas não com sangue de hamster. Embora o sangue de frango foi menos eficaz do que o sangue de hamster sobre o potencial biológico de L. migonei e L. ovallesi, não exclui o sangue de frango como uma fonte de sangue para a manutenção das populações de ambas as espécies nas casas.

Animal rights, animal minds, and human mindreading.

Science.gov (United States)

Mameli, M; Bortolotti, L

2006-02-01

Do non-human animals have rights? The answer to this question depends on whether animals have morally relevant mental properties. Mindreading is the human activity of ascribing mental states to other organisms. Current knowledge about the evolution and cognitive structure of mindreading indicates that human ascriptions of mental states to non-human animals are very inaccurate. The accuracy of human mindreading can be improved with the help of scientific studies of animal minds. However, the scientific studies do not by themselves solve the problem of how to map psychological similarities (and differences) between humans and animals onto a distinction between morally relevant and morally irrelevant mental properties. The current limitations of human mindreading-whether scientifically aided or not-have practical consequences for the rational justification of claims about which rights (if any) non-human animals should be accorded.

METHODS: Data were collected in the LILACS and SciELO databases, Nursing journals and on http://www.google.com.br. Articles focusing on blood transfusion in JWs were included, and texts that were repeated or did not approach this theme were excluded. Content analysis was used. RESULTS: The thematic categories show that the JWs accept self-transfusion and are opposed to the medical practice of blood transfusion, even if it represents the continuity of life. CONCLUSION: Healthcare professionals experience ethical dilemmas when they need to perform blood transfusion in JWs due to the fact that religious freedom is not an absolute value, and the apparent collision of fundamental rights demands that a decision be made, centered on legal standards and bioethical principles.OBJETIVO: Identificar la producción de conocimiento por los profesionales de salud respecto a la transfusión sanguínea de Testigos de Jeova (TJ, listar las alternativas terapéuticas de la transfusión sanguínea en esos individuos y citar la ordenanza jurídica, ética y bioética en lo que concierne a la transfusión sanguínea en TJ.

Full Text Available Interactions that animals experience can have a significant influence on their health and welfare. These interactions can occur between animals themselves, but also between animals and keepers, and animals and the public. Human and non-human animals come into contact with each other in a variety of settings, and wherever there is contact there is the opportunity for interaction to take place. Interaction with companion animals are well known, but human–animal interaction (HAR (Hosey, 2008 also occurs in the context of farms (Hemsworth and Gonyou, 1997; Hemsworth, 2003, laboratories (Chang and Hart, 2002, zoos (Kreger and Mench, 1995 and even the wild (e.g. Cassini, 2001. This project proposes a permanent monitoring scheme to record animal-human interactions and animal-animal interactions in zoos. This will be accompanied by a survey of animal personality for welfare, husbandry, breeding programs and reintroduction purposes. The pilot project is currently based on direct monitoring of animal behaviour, use of time lapse cameras and animal personality questionnaires completed by experienced keepers. The goal of this project is to create a network between zoos to explore the aforementioned interactions to produce husbandry protocols and explore personality and behavioural traits in multiple species. We present provisional data regarding polar bear (Fasano Zoosafari, Italy, Sumatran tigers, Amur tigers and Asiatic lion (ZSL London and Whipsnade zoo interactions with humans and conspecifics. This data is collected across a broad range of environmental conditions and outlines the monitoring protocols developed to collect this data. The first year data show the great adaptability of these species to ex situ environments, low or absent negative impact of visitors’ presence and the relevance of individual personality in these interactions.

In this animic ontology, beings do not propel themselves across a ready-made world but rather issue forth through a world-in-formation, along the lines of their relationships. To its inhabitants this weather-world, embracing both sky and earth, is a source of astonishment but not surprise. Re-animating the ‘western’ tradition of thought means recovering the sense of astonishment banished from offi cial science.

Animal welfare and use of silkworm as a model animal.

Sacrificing model animals is required for developing effective drugs before being used in human beings. In Japan today, at least 4,210,000 mice and other mammals are sacrificed to a total of 6,140,000 per year for the purpose of medical studies. All the animals treated in Japan, including test animals, are managed under control of "Act on Welfare and Management of Animals". Under the principle of this Act, no person shall kill, injure, or inflict cruelty on animals without due cause. "Animal" addressed in the Act can be defined as a "vertebrate animal". If we can make use of invertebrate animals in testing instead of vertebrate ones, that would be a remarkable solution for the issue of animal welfare. Furthermore, there are numerous advantages of using invertebrate animal models: less space and small equipment are enough for taking care of a large number of animals and thus are cost-effective, they can be easily handled, and many biological processes and genes are conserved between mammals and invertebrates. Today, many invertebrates have been used as animal models, but silkworms have many beneficial traits compared to mammals as well as other insects. In a Genome Pharmaceutical Institute's study, we were able to achieve a lot making use of silkworms as model animals. We would like to suggest that pharmaceutical companies and institutes consider the use of the silkworm as a model animal which is efficacious both for financial value by cost cutting and ethical aspects in animals' welfare.

Full Text Available Objetivou-se com este estudo avaliar os impactos de se ignorarem os efeitos de dominância sobre a estimação de parâmetros genéticos e a predição de valores genéticos pelo método da máxima verossimilhança restrita sob modelo animal aditivo empregando-se o MTDFREML. Para a mesma arquitetura genômica, foram simulados dois modelos de ação gênica: um deles incluiu apenas efeitos aditivos dos genes e o outro, efeitos aditivos e dominância completa e positiva para 100% dos locos. Sob cada modelo genético, foram geradas três populações-base correspondentes às características com herdabilidades de 0,15 (baixa, 0,30 (média e 0,60 (alta. A partir das populações-base, foram geradas as populações iniciais, que, submetidas a seleção e a acasalamentos ao acaso, durante seis gerações consecutivas e discretas, resultaram cada uma em 18.000 indivíduos com registro. As estimativas dos componentes de variância e herdabilidade obtidas no modelo com ação gênica aditiva foram semelhantes aos seus valores reais para todas as características, ao passo que, sob ação gênica de dominância, todos os componentes foram superestimados, principalmente a variância genética aditiva. A variância de dominância não-estimada pelo modelo animal adotado foi redistribuída entre os componentes genético aditivo e residual estimados. Houve perda na acurácia da avaliação genética sob o modelo genético com dominância e essa perda foi traduzida por correlações mais baixas entre os valores genéticos verdadeiros e preditos dos animais. Há necessidade de novos estudos, já que os genomas simulados podem não corresponder aos sistemas biológicos verdadeiros.The objective of this study was to evaluate impacts of ignoring the dominance effects on the estimation of genetic parameters and prediction of genetic values by the restricted maximum likelihood method, under the additive animal model, using MTDFREML.

2013-11-01

In the past few years, new social passions have sparked on the Chinese mainland. At the centre of these burgeoning passions is a focus on animal welfare, animal treatment, and even animal rights, by the public and academic sectors. With China's rapid economic changes and greater access to information from around the world, societal awareness of animal issues is rising very fast. Hastening this paradigm shift were several highly public incidents involving animal cruelty, including exposés on bear bile harvesting for traditional Chinese medicine, the thousands of dogs rescued from China's meat trade, and the call to boycott shark fin soup and bird nest soup. This article outlines the current status of campaigning by animal advocates in China (specifically the animal rights movement) from three interlinked perspectives: wildlife conservation, companion animal protection, and laboratory animal protection. By reviewing this campaigning, we attempt to present not only the political and social impact of the concept of animal rights, but also the perceptions of, and challenges to, animal rights activities in China. 2013 FRAME.

Seeing the animal

Harfeld, Jes Lynning; Cornou, Cecile; Kornum, Anna

2016-01-01

This article discusses the notion that the invisibility of the animalness of the animal constitutes a fundamental obstacle to change within current production systems. It is discussed whether housing animals in environments that resemble natural habitats could lead to a re-animalization...... of the animals, a higher appreciation of their moral significance, and thereby higher standards of animal welfare. The basic claim is that experiencing the animals in their evolutionary and environmental context would make it harder to objectify animals as mere bioreactors and production systems. It is argued...... that the historic objectification of animals within intensive animal production can only be reversed if animals are given the chance to express themselves as they are and not as we see them through the tunnel visions of economy and quantifiable welfare assessment parameters....

Gaps in US Animal Welfare Law for Laboratory Animals: Perspectives From an Animal Law Attorney.

Science.gov (United States)

Frasch, Pamela D

2016-05-01

The use of animals in biomedical, toxicological, and basic research has been common practice, and a tool for scientists and researchers, for many years. And yet, serious conflict continues to exist between those who believe that the use of animals in research will yield scientific results that benefit humans and those who believe such practices are unethical regardless of use or outcome. High-profile undercover cases have further raised public awareness and have put the entire industry under pressure to be transparent, accountable, and aggressive in its adoption of reduction, refinement, and replacement (3R) principles. Many animal law attorneys are deeply frustrated by what they see as weak US laws that are unevenly enforced, especially when compared with legal advances in other countries and regions. This article (1) explores those gaps in US animal welfare laws with an emphasis on the Animal Welfare Act, (2) argues in favor of stronger laws and rigorous enforcement, and (3) suggests steps to advance these goals. These steps include (1) expanding the definition of "animal" in the Animal Welfare Act (AWA), (2) improving and expanding minimum care requirements in USDA regulations, (3) instituting mandatory reporting requirements, improving Institutional Animal Care and Use Committees, and allowing easier accessibility to laboratory reports and plans, (4) adding a citizen suit provision to the AWA, and (5) continuing education about the emotional and social capacities of animals and a stronger commitment to 3R principles. © The Author 2017.

Concepts of animal welfare in relation to positions in animal ethics.

Science.gov (United States)

Schmidt, Kirsten

2011-06-01

When animal ethicists deal with welfare they seem to face a dilemma: On the one hand, they recognize the necessity of welfare concepts for their ethical approaches. On the other hand, many animal ethicists do not want to be considered reformist welfarists. Moreover, animal welfare scientists may feel pressed by moral demands for a fundamental change in our attitude towards animals. The analysis of this conflict from the perspective of animal ethics shows that animal welfare science and animal ethics highly depend on each other. Welfare concepts are indispensable in the whole field of animal ethics. Evidence for this can be found by analyzing the structure of theories of animal ethics and the different ways in which these theories employ welfare concepts. Furthermore, the background of values underneath every welfare theory is essential to pursue animal welfare science. Animal ethics can make important contributions to the clarification of underlying normative assumptions with regard to the value of the animal, with regard to ideas about what is valuable for the animal, and with regard to the actions that should follow from the results of animal welfare science.

[Alternatives to animal experimentation v.s. animal rights terrorism].

Science.gov (United States)

Kurosawa, Tsutomu Miki

2008-05-01

Systematic modern animal experimentation was established by Bernard Claude who wrote "An Introduction to the Study of Experimental Medicine" in 1865. At this point, the public was already asking that the pain and distress of experimental animals be reduced. For this, scientists, William Russell and Rex Burch in 1959 proposed the principles of alternatives to animal experimentation, the "3Rs". Since that time, animal welfare advocates have promoted the 3Rs concept in biomedical research communities. However, cruel animal experiments have continued and there are reports of radical extremists showing their opposition by invasion, arson, theft and even bombing of institutions involved, resulting in killing of the animals. SHAC, one extremist group believed to be animal welfare activitists was recognized as a terrorist group after the 9.11 tragedy in USA and the government viewed their activities very seriously. In 2001, British animal extremists invaded Japanese universities and stole laboratory resources; one individual was arrested and sentenced to prison for three years; Japanese who assisted in the incident were arrested and one was sentenced for one year. In 2006, SHAC USA members were prosecuted and sentenced for up to 6 years for their terrorism activities including arson. We need to consider the background of these activities which are financially supported by animal welfare advocates. The way we, as scientists who conduct such experiments can respond is by promoting alternatives to this experimentation. In Japan, the animal welfare law was revised in 2005 stressing the importance of 3Rs in scientific activities with animals. The promotion of 3Rs should be strengthened in the pharmaceutical community.

O delineamento empregado foi o completamente casualizado. As vacas sob suplementação com sal aniônico apresentaram menor pH urinário e aumento das concentrações sanguíneas de ureia, cálcio e magnésio. Com a dieta aniônica, o leite precipitou com menores concentrações de etanol, apresentou menor densidade, porcentagens de lactose, proteína e imunoglobulina, porém maior teor de cálcio iônico. O fornecimento de dieta aniônica durante a lactação resultou em acidose metabólica, o que alterou o perfil bioquímico sanguíneo e as características físico-químicas do leite.The objective of this work was to evaluate the inclusion of anionic salt in the diet on the physical characteristics and chemical composition of milk, biochemical blood profile, milk yield, body weight and condition. It was used 20 Jersey cows, distributed into two diets, a diet with no addition of anionic salt and one diet with addition of 0.25 kg/day of ammonium chloride. It was used a completely randomized design. Cows supplemented with anionic salt presented lower urinary pH and increase of blood contents of urea, calcium and magnesium. With the anionic diet, milk precipitated with lower ethanol concentration and it presented lower density, percentages of lactose, protein and immunoglobulin, but higher ionic calcium content. Supply of anionic diet during lactation resulted in metabolic acidosis, which altered the blood biochemical profile and milk physical-chemical characteristics.

The Animal Health Act that replaces the Animal Disease Act, which is currently in force, creates a regulatory framework in order to not only, as has been the case so far, control animal diseases that had already broken out, but in order to already prevent in advance possible outbreaks of animal diseases by means of preventive measures. The instruments to this effect are described here. At European level, too, the idea of prevention is set to play a greater role in the future, with the draft EU legal instrument on animal health, that has to date only been discussed at Commission level, also contributing to a simplification and easier implementation by the persons subject to law by harmonising the currently fragmented Community law. It remains to be seen when the deliberations in the Council and European Parliament will begin.

Adapting Animal-Assisted Therapy Trials to Prison-Based Animal Programs.

Science.gov (United States)

Allison, Molly; Ramaswamy, Megha

2016-09-01

Prison-based animal programs have shown promise when it comes to increased sociability, responsibility, and levels of patience for inmates who participate in these programs. Yet there remains a dearth of scientific research that demonstrates the impact of prison-based animal programs on inmates' physical and mental health. Trials of animal-assisted therapy interventions, a form of human-animal interaction therapy most often used with populations affected by depression/anxiety, mental illness, and trauma, may provide models of how prison-based animal program research can have widespread implementation in jail and prison settings, whose populations have high rates of mental health problems. This paper reviews the components of prison-based animal programs most commonly practiced in prisons today, presents five animal-assisted therapy case studies, evaluates them based on their adaptability to prison-based animal programs, and discusses the institutional constraints that act as barriers for rigorous prison-based animal program research implementation. This paper can serve to inform the development of a research approach to animal-assisted therapy that nurses and other public health researchers can use in working with correctional populations. © 2016 Wiley Periodicals, Inc.

Does the Animal Welfare Act apply to free-ranging animals?

Mulcahy, Daniel M.

2003-01-01

Despite the long-standing role that institutional animal care and use committees (IACUCs) have played in reviewing and approving studies at academic institutions, compliance with the Animal Welfare Act (AWA) is not always complete for government natural resource agencies that use free-ranging animals in research and management studies. Even at universities, IACUCs face uncertainties about what activities are covered and about how to judge proposed research on free-ranging animals. One reason for much of the confusion is the AWA vaguely worded exemption for "field studies." In particular, fish are problematic because of the AWA exclusion of poikilothermic animals. However, most university IACUCs review studies on all animals, and the Interagency Research Animal Committee (IRAC) has published the "IRAC Principles," which extend coverage to all vertebrates used by federal researchers. Despite this extended coverage, many scientists working on wild animals continue to view compliance with the AWA with little enthusiasm. IACUCs, IACUC veterinarians, wildlife veterinarians, and fish and wildlife biologists must learn to work together to comply with the law and to protect the privilege of using free-ranging animals in research.

Animal Bodies, Colonial Subjects: (ReLocating Animality in Decolonial Thought

Directory of Open Access Journals (Sweden)

Billy-Ray Belcourt

2014-12-01

Full Text Available In this paper, I argue that animal domestication, speciesism, and other modern human-animal interactions in North America are possible because of and through the erasure of Indigenous bodies and the emptying of Indigenous lands for settler-colonial expansion. That is, we cannot address animal oppression or talk about animal liberation without naming and subsequently dismantling settler colonialism and white supremacy as political machinations that require the simultaneous exploitation and/or erasure of animal and Indigenous bodies. I begin by re-framing animality as a politics of space to suggest that animal bodies are made intelligible in the settler imagination on stolen, colonized, and re-settled Indigenous lands. Thinking through Andrea Smith’s logics of white supremacy, I then re-center anthropocentrism as a racialized and speciesist site of settler coloniality to re-orient decolonial thought toward animality. To critique the ways in which Indigenous bodies and epistemologies are at stake in neoliberal re-figurings of animals as settler citizens, I reject the colonial politics of recognition developed in Sue Donaldson and Will Kymlicka’s recent monograph, Zoopolis: A Political Theory of Animal Rights (Oxford University Press 2011 because it militarizes settler-colonial infrastructures of subjecthood and governmentality. I then propose a decolonized animal ethic that finds legitimacy in Indigenous cosmologies to argue that decolonization can only be reified through a totalizing disruption of those power apparatuses (i.e., settler colonialism, anthropocentrism, white supremacy, and neoliberal pluralism that lend the settler state sovereignty, normalcy, and futurity insofar as animality is a settler-colonial particularity.

Full Text Available Animated graphs that demonstrate statistical ideas and methods can both attract interest and assist understanding. In this paper we first discuss how animations can be related to some statistical topics such as iterative algorithms, random simulations, (resampling methods and dynamic trends, then we describe the approaches that may be used to create animations, and give an overview to the R package animation, including its design, usage and the statistical topics in the package. With the animation package, we can export the animations produced by R into a variety of formats, such as a web page, a GIF animation, a Flash movie, a PDF document, or an MP4/AVI video, so that users can publish the animations fairly easily. The design of this package is flexible enough to be readily incorporated into web applications, e.g., we can generate animations online with Rweb, which means we do not even need R to be installed locally to create animations. We will show examples of the use of animations in teaching statistics and in the presentation of statistical reports using Sweave or knitr. In fact, this paper itself was written with the knitr and animation package, and the animations are embedded in the PDF document, so that readers can watch the animations in real time when they read the paper (the Adobe Reader is required.Animations can add insight and interest to traditional static approaches to teaching statistics and reporting, making statistics a more interesting and appealing subject.

Animal experimentation.

Science.gov (United States)

Kolar, Roman

2006-01-01

Millions of animals are used every year in often times extremely painful and distressing scientific procedures. Legislation of animal experimentation in modern societies is based on the supposition that this is ethically acceptable when certain more or less defined formal (e.g. logistical, technical) demands and ethical principles are met. The main parameters in this context correspond to the "3Rs" concept as defined by Russel and Burch in 1959, i.e. that all efforts to replace, reduce and refine experiments must be undertaken. The licensing of animal experiments normally requires an ethical evaluation process, often times undertaken by ethics committees. The serious problems in putting this idea into practice include inter alia unclear conditions and standards for ethical decisions, insufficient management of experiments undertaken for specific (e.g. regulatory) purposes, and conflicts of interest of ethics committees' members. There is an ongoing societal debate about ethical issues of animal use in science. Existing EU legislation on animal experimentation for cosmetics testing is an example of both the public will for setting clear limits to animal experiments and the need to further critically examine other fields and aspects of animal experimentation.

Keeper-Animal Interactions: Differences between the Behaviour of Zoo Animals Affect Stockmanship.

Stockmanship is a term used to describe the management of animals with a good stockperson someone who does this in a in a safe, effective, and low-stress manner for both the stock-keeper and animals involved. Although impacts of unfamiliar zoo visitors on animal behaviour have been extensively studied, the impact of stockmanship i.e familiar zoo keepers is a new area of research; which could reveal significant ramifications for zoo animal behaviour and welfare. It is likely that different relationships are formed dependant on the unique keeper-animal dyad (human-animal interaction, HAI). The aims of this study were to (1) investigate if unique keeper-animal dyads were formed in zoos, (2) determine whether keepers differed in their interactions towards animals regarding their attitude, animal knowledge and experience and (3) explore what factors affect keeper-animal dyads and ultimately influence animal behaviour and welfare. Eight black rhinoceros (Diceros bicornis), eleven Chapman's zebra (Equus burchellii), and twelve Sulawesi crested black macaques (Macaca nigra) were studied in 6 zoos across the UK and USA. Subtle cues and commands directed by keepers towards animals were identified. The animals latency to respond and the respective behavioural response (cue-response) was recorded per keeper-animal dyad (n = 93). A questionnaire was constructed following a five-point Likert Scale design to record keeper demographic information and assess the job satisfaction of keepers, their attitude towards the animals and their perceived relationship with them. There was a significant difference in the animals' latency to appropriately respond after cues and commands from different keepers, indicating unique keeper-animal dyads were formed. Stockmanship style was also different between keepers; two main components contributed equally towards this: "attitude towards the animals" and "knowledge and experience of the animals". In this novel study, data demonstrated unique dyads

Full Text Available INTRODUCTION: HTLV-1/2 screening among blood donors commonly utilizes an enzyme-linked immunosorbent assay (EIA, followed by a confirmatory method such as Western blot (WB if the EIA is positive. However, this algorithm yields a high rate of inconclusive results, and is expensive. METHODS: Two qualitative real-time PCR assays were developed to detect HTLV-1 and 2, and a total of 318 samples were tested (152 blood donors, 108 asymptomatic carriers, 26 HAM/TSP patients and 30 seronegative individuals. RESULTS: The sensitivity and specificity of PCR in comparison with WB results were 99.4% and 98.5%, respectively. PCR tests were more efficient for identifying the virus type, detecting HTLV-2 infection and defining inconclusive cases. CONCLUSIONS: Because real-time PCR is sensitive and practical and costs much less than WB, this technique can be used as a confirmatory test for HTLV in blood banks, as a replacement for WB.INTRODUÇÃO: A triagem para HTLV-1/2 em doadores de sangue geralmente utiliza imunoensaio enzimático, seguido de um método confirmatório como Western blot quando o EIA é positivo, mas este algoritmo mostra alta taxa de resultados inconclusivos, e elevado custo. MÉTODOS: Dois ensaios qualitativos de PCR em tempo real foram desenvolvidos para detectar HTLV-1 e 2 e um total de 318 amostras foram testadas por PCR (152 de doadores de sangue, 108 de portadores assintomáticos, 26 de pacientes HAM/TSP e 30 de indivíduos soronegativos. RESULTADOS: A sensibilidade e especificidade das PCR em relação aos resultados de WB foram de 99,4% e 98,5%, respectivamente. As PCR foram mais eficientes em identificar o tipo viral, a infecção pelo HTLV-2 e úteis para definir casos inconclusivos. CONCLUSÕES: Por serem sensíveis, práticas e de custo muito inferior ao do WB, as técnicas de PCR em tempo real podem ser usadas como teste confirmatório do HTLV em bancos de sangue, em substituição ao WB.

Chuvas simuladas na intensidade de 64 mm h-1 e duração de 60 a 105 min foram aplicadas em quatro épocas: logo após a semeadura, 30 e 60 dias após a emergência e logo após a colheita do milho. A cobertura do solo propiciada pela cultura de inverno foi reduzida em 90% após o preparo convencional, independentemente da forma de tração. As perdas de solo e água medidas durante o desenvolvimento do milho foram sempre maiores sob preparo convencional do que sob plantio direto, independentemente da forma de tração, exceto logo após a colheita, quando a resteva estava uniformemente distribuída na superfície do solo. No preparo convencional, a erosão na cultura do milho foi, na média das formas de tração, 45% menor, quando antecedida de aveia preta no inverno do que quando antecedida de pousio descoberto. Por sua vez, a cultura do milho, por si só, reduziu a erosão em 60%, na média das formas de tração, comparada à do solo descoberto. A forma de tração influenciou a erosão somente no preparo convencional, com a animal apresentando perdas totais de solo 55 e 15% inferiores à tratorizada, respectivamente na cultura do milho e em solo descoberto. A perda de água por enxurrada foi mais afetada pela forma de tração no preparo convencional, totalizando, em média, 44% na animal e 57% na tratorizada, em relação ao volume total de chuva aplicado.

Solidarity with Animals: Assessing a Relevant Dimension of Social Identification with Animals.

Interactions with animals are pervasive in human life, a fact that is reflected in the burgeoning field of human-animal relations research. The goal of the current research was to examine the psychology of our social connection with other animals, by specifically developing a measure of solidarity with animals. In 8 studies using correlational, experimental, and longitudinal designs, solidarity with animals predicted more positive attitudes and behaviors toward animals, over and above existing scales of identification, and even when this implied a loss of resources and privileges for humans relative to animals. Solidarity with animals also displayed predicted relationships with relevant variables (anthropomorphism, empathy). Pet owners and vegetarians displayed higher levels of solidarity with animals. Correlational and experimental evidence confirmed that human-animal similarity heightens solidarity with animals. Our findings provide a useful measure that can facilitate important insights into the nature of our relationships with animals.

Blood tranfusion in critically ill patients: state of the art Transfusão de sangue em pacientes críticos: estado da arte

Full Text Available Anemia is one of the most common abnormal findings in critically ill patients, and many of these patients will receive a blood transfusion during their intensive care unit stay. However, the determinants of exactly which patients do receive transfusions remains to be defined and have been the subject of considerable debate in recent years. Concerns and doubts have emerged regarding the benefits and safety of blood transfusion, in part due to the lack of evidence of better outcomes resulting from randomized studies and in part related to the observations that transfusion may increase the risk of infection. As a result of these concerns and of several studies suggesting better or similar outcomes with a lower transfusion trigger, there has been a general tendency to decrease the transfusion threshold from the classic 10 g/dL to lower values. In this review, we focus on some of the key studies providing insight into current transfusion practices and fueling the current debate on the ideal transfusion trigger.A transfusão no paciente crítico vem sendo alvo de discussões recentes considerando seus reais benefícios na redução de morbi-mortalidade e os riscos associados ao procedimento. Nos últimos anos, alguns estudos controlados e randomizados tiveram como objetivo comparar desfechos clínicos entre pacientes que receberam transfusão de maneira mais liberal (hemoglobina alvo em torno de 9 g/dL e transfusão de maneira mais restritiva (hemoglobina em torno de 7 g/dL. Os resultados demonstram a não superioridade da estratégia liberal comparada com a restritiva. Além disso, em alguns subgrupos de pacientes menos graves ou de menor idade, a transfusão foi associada com piores desfechos clínicos. Os riscos da transfusão de sangue no paciente crítico incluem desde incidência maior de infecções bacterianas, infecções virais, imunodepressão, reações hemolíticas e lesões teciduais inflamatórias, dentre outros.

[Animal ethics in the 19th century and Swiss animal protection law].

Bloch, I

The development of animal ethics and animal rights from the antiquity up to modern times is described. The relationship of humans to animals was primarily based on fear and animal cult, developed by the domestication to a partnership. The philosophers of the early modern age denied the animals the reason, what was disadvantageous to the position of the animals in the society and the behavior of humans to the animals. By the end of the 19th century the animal protection concept developed with numerous postulates for legal regulations. With the Swiss animal protection law, which came into force in 1981, most of the postulates could be realised. It is shown, how animal protection has developed since that time.

Instruction in animal-assisted therapy (AAT) and animal-assisted activities (AAAs) teaches veterinary medical students to confidently and assertively maximize the benefits and minimize the risks of this union of animals and people. Instruction in AAT/AAA also addresses requirements by the American Veterinary Medical Association Council on Education that accredited schools/colleges of veterinary medicine include in their standard curriculum the topics of the human-animal bond, behavior, and the contributions of the veterinarian to the overall public and professional health care teams. Entry-level veterinarians should be prepared to: (1) assure that animals who provide AAT/AAA are healthy enough to visit nursing homes, hospitals, or other institutions; (2) promote behavior testing that selects animals who will feel safe, comfortable, and connected; (3) advise facilities regarding infection control and ways to provide a safe environment where the animals, their handlers, and the people being visited will not be injured or become ill; and (4) advocate for their patients and show compassion for their clients when animals are determined to be inappropriate participants in AAT/AAA programs. This article presents AAT/AAA terminology, ways in which veterinarians can advocate for AAT/AAA, the advantages of being involved in AAT/AAA, a model AAT/AAA practicum from Tuskegee University's School of Veterinary Medicine (TUSVM), and examples of co-curricular activities in AAT/AAA by TUSVM's student volunteers.

This review explores animal allergen exposure in research laboratories and other work settings, focusing on causes and prevention. (1) Consistent with the hygiene hypothesis, there is new evidence that early childhood exposure to pets produces changes in the gut microbiome that likely lead to a lower risk of allergy. (2) Anaphylaxis from laboratory animal bites occurs more frequently than suggested by prior literature. (3) Animal allergens represent an occupational hazard in a wide variety of work settings ranging from fields that work with animals to public settings like schools and public transportation where allergens are brought into or are present in the workplace. Exposure to animal allergens can result in allergy, asthma, and anaphylaxis. Animal allergy has been most studied in the research laboratory setting, where exposure reduction can prevent the development of allergy. Similar prevention approaches need to be considered for other animal work environments and in all settings where animal allergens are present.

Positive animal welfare states and encouraging environment-focused and animal-to-animal interactive behaviours.

Science.gov (United States)

Mellor, D J

2015-01-01

Affective neuroscience, incorporating neurophysiology and neuropsychology, is providing increasing evidence that certain behaviours of animals may be interpreted in terms of what they are intending to achieve, i.e. their goals. It is also providing evidence that allows inferences to be made about the affective contents of some goal-directed behaviours. These neuroscience-supported inferences are aligned with recommendations based on prior behaviour-based investigations of animals' preferences, aversions and priorities, and these observations together support the cautious use of particular behaviours to infer what the accompanying affects may be. In this review, therefore, some attention is given to negative affects and their relationships to poor animal welfare, but the primary focus is the positive affects animals may experience when they successfully engage in rewarding goal-directed behaviours, encapsulated in the concept of positive affective engagement. The review draws together reports of environment-focused and animal-to-animal interactive behaviours observed in a range of species and under diverse circumstances in order to illustrate the likely widespread occurrence of the positive affects that may accompany them. Particular consideration is given to affects that are potentially associated with some aspects of exploration and food acquisition in stimulus rich or impoverished environments, and to those that may be associated with aspects of the affiliative interactions of bonding or bond affirmation, maternal care, play and sexual activity. It is concluded that animals given the opportunity to engage in such activities may experience some positive affects. However, the intensity of an animal's experience of particular positive affects is likely to range from zero to very high because the associated behaviours occur intermittently, variation may occur during different phases of a goal-directed behaviour, and other positive or negative affects experienced at

Thirty six (22% tested HIV seropositive. The univariate and multivariate analysis (logistic model demonstrated that the risk of HIV infection during the study period was associated with the total units of acellular blood components transfused. In addition, the proportional contribution of the individual components to the total acellular units transfused, namely a increase in factor VIII/IX and lyophilized cryoprecipitate proportions, were found to be associated with HIV seropositivity. This analysis suggest that not only the total amount of units was an important determinant of HIV infection, but that the risk was also associated with the specific component of blood transfusedResultados de um estudo da prevalência de infecção pelo VIH, realizado em hemofílicos em Belo Horizonte são apresentados.

Commodifying animals: ethical issues in genetic engineering of animals.

Science.gov (United States)

Almond, B

2000-03-01

The genetic modification of living beings raises special ethical concerns which go beyond general discussion of animal rights or welfare. Although the goals may be similar, biotechnology has accelerated the process of modification of types traditionally carried out by cross-breeding. These changes are discussed in relation to two areas: biomedicine, and animal husbandry. Alternative ethical approaches are reviewed, and it is argued that the teleological thesis underlying virtue ethics has special relevance here. The case for and the case against genetic engineering and patenting of life-forms are examined, and conclusions are drawn which favour regulation, caution and respect for animals and animal species.

Enclosure for small animals during awake animal imaging

Goddard, Jr., James S

2013-11-26

An enclosure or burrow restrains an awake animal during an imaging procedure. A tubular body, made from a radiolucent material that does not attenuate x-rays or gamma rays, accepts an awake animal. A proximal end of the body includes an attachment surface that corresponds to an attachment surface of an optically transparent and optically uniform window. An anti-reflective coating may be applied to an inner surface, an outer surface, or both surfaces of the window. Since the window is a separate element of the enclosure and it is not integrally formed as part of the body, it can be made with optically uniform thickness properties for improved motion tracking of markers on the animal with a camera during the imaging procedure. The motion tracking information is then used to compensate for animal movement in the image.

The Protection of Animals in Thailand--An Insight into Animal Protection Legislation

2017-09-01

Full Text Available There are many critics of current Thai law concerning the welfare of animals. They argue that the PACPAWA,2014 is inadequate to protect the welfare of animals. The absence of clear guidelines in the legislation concerning animal welfare has resulted in animal welfare receiving inadequate protection. There are other limitations contributing to the inadequacy of existing laws in protecting animals in Thailand. The possible penalties are very low. For the offence of cruelty against an animal, the PACPAWA,2014 sets a maximum fine of TBH 2000. This is considered inadequate and ineffective in preventing cruelty to animals. The study utilises doctrinal legal research or library-based research approach to provide valuable insights in understanding the law and and ascertaining the principles of legal interpretation and analysis. The study also provides possible suggestions to enhance the protection of the welfare of animals in Thailand. The research suggests that education should play an important role in promoting kindness towards animals.

Human-animal relationships: from daily life to animal-assisted therapies

Full Text Available Humans have a long history of relationship with domestic animals and nowadays pets often act as "social substitutes" through bonding. There is some evidence that pet presence at home may induce well being in people and the development of social skills in children. Animal assisted therapies aim at developing these skills in patients on the basis of human animal interactions. Experimental data obtained on animal models suggest that this is indeed a promising line.

Improvements are observed, but again sound scientific data are mostly missing. Attention must be given to the welfare of the animals being used.

Comparing the Effect of Animal-Rearing Education in Japan with Conventional Animal-Assisted Education.

Science.gov (United States)

Nakajima, Yuka

2017-01-01

An increasing number of teachers are introducing animals into their class so that pupils foster cognitive, physiological, and social skills through their interaction with animals. Along with such an educational style termed animal-assisted education (AAE), Japanese formal education has also utilized animals for education. Japanese animal-rearing education is unique regarding the following two points: (1) it takes the form of "education through assisting animals" rather than "animals assisting education" and (2) animal rearing is embedded in formal education. While conventional AAE expects the benefit from the social support of animals, Japanese animal-rearing education expects benefit from nurturing and caring for animals. The present study aims to identify effective methods for using animals for education by highlighting the benefits of Japanese animal-rearing education. An overview of Japanese animal-rearing education is followed by a critical review of empirical studies of conventional AAE and Japanese animal-rearing education. Despite the differences in the educational styles, it was found that both systems commonly help children adapt to school. Additionally, conventional AAE were effective in enhancing cognitive and athletic ability of students and foster social skills, while Japanese animal-rearing education enhanced academic knowledge and skills and cultivated sympathy for animals and other people. Furthermore, it was demonstrated that the experience of raising animals affects children's development for a long time even after children stop raising animals. In order to determine the effect of animal presence at school, however, more empirical studies with various viewpoints are necessary for both styles of education. Concerning Japanese animal-rearing education, the effects of the differences such as the amount of exposure to animals, developmental stage or character of individual children, the types of animals need to be controlled for a more sophisticated

JUNGIAN GENDER IN ANIMAL ANIMATION FROM ANTHROPOMORPHISM PERSPECTIVE

Directory of Open Access Journals (Sweden)

Yustin Sartika

2017-12-01

Full Text Available Bear is usually depicted as a strong, brawny and blood-curdling animal. On the contrary, Pooh Bear is the fun-loving and caring main character while Masha Bear can handle all house works. Their characteristics can be related to Jungian gender theory which states that man is bisexual having both feminine and masculine sides. A focus on anima animus is established through qualitative research analysis of bear characters' actions and the characters around within the plots of Winnie-the-Pooh and Masha and the Bear. Masha and the Bear is adapted from the real story in Russia. The use of anthropomorphic storytelling in those animations can bridge the conceptual and moral gulf which separate human from animal. By using anthropomorphism perspective, this research is aimed to find the feminine and masculine stereotype of Pooh and Bear characters. Anthropomorphism is divided into the animation of physical and psychological qualities. The result shows that small bright yellow body on a short red t-shirt makes Pooh look more lovable. Another woman stereotype is portrayed from the name given, Winnie, and his most favorite honey. Masha Bear‘s physical qualities are quite identical to a real bear. Beyond his strong and brawny body, he is a spick-and-span bear. He is a merciful bear who becomes a caregiver for Masha, the parentless girl. Anthropomorphism creates great empathy in humans. This empathy can be combined with a simplified narrative to provoke genuine feeling from audiences. It draws attention to feminine and masculine stereotype of human to identify in animal animation.

Brückner, G K

2009-03-01

The international trade in animals and animal products has become a sensitive issue for both developed and developing countries by posing an important risk for the international spread of animal and human pathogens whilst at the same time being an essential activity to ensure world-wide food security and food safety. The OIE has since its founding in 1924, applied a democratic and transparent decision-making process to continuously develop and review international standards for animal health and zoonoses to facilitate trade in animals and animal products. The role of the OIE is also mandated by the World Trade Organization (WTO) as international reference point for standards related to animal health. In support of its overall objective of promoting animal health world-wide, the OIE has also launched several other initiatives such as the improvement of the governance of veterinary services within its member countries and territories and to enhance the availability of diagnostic and scientific expertise on a more even global geographical distribution. Several trade facilitating concepts such as country, zonal and compartment freedom from disease as well the trade in disease free commodities has been introduced to enhance the trade in animals and animal products for all its members including those from developing and transitional countries who are still in the process of enhancing to full compliance with international sanitary standards.

Carotenoids in Marine Animals

Science.gov (United States)

Maoka, Takashi

2011-01-01

Marine animals contain various carotenoids that show structural diversity. These marine animals accumulate carotenoids from foods such as algae and other animals and modify them through metabolic reactions. Many of the carotenoids present in marine animals are metabolites of β-carotene, fucoxanthin, peridinin, diatoxanthin, alloxanthin, and astaxanthin, etc. Carotenoids found in these animals provide the food chain as well as metabolic pathways. In the present review, I will describe marine animal carotenoids from natural product chemistry, metabolism, food chain, and chemosystematic viewpoints, and also describe new structural carotenoids isolated from marine animals over the last decade.

Full Text Available OBJETIVO: Estudar aspectos da epidemiologia da hepatite B em pessoas submetidas à coleta de sangue em unidades de saúde. MÉTODOS: Indivíduos dos quais se coletou sangue em unidades de saúde de Ribeirão Preto, independentemente do motivo, foram solicitados a fornecer uma quantidade adicional de material, obtida no momento da coleta e submetida à detecção de marcadores de hepatite B. Simultaneamente, por meio de questionário padronizado, foram obtidas informações de possíveis fatores de risco para a doença. Os dados foram analisados por meio de um modelo de regressão logística. RESULTADOS: As prevalências de HBsAg e de anti-HBcAg foram de 0,3% e 13,9%, respectivamente. Os fatores de risco associados à infecção foram: idade, residência na cidade há menos de um ano, antecedente de hepatite, exposição prévia a casas de correção e homo/bissexualismo masculino. CONCLUSÕES: Devido a dificuldades crescentes de obtenção de sangue de indivíduos sadios, essa pode ser uma alternativa para estudos que objetivem fornecer informações sobre a circulação de agentes infecciosos na população.

Mentalizing animals

DEFF Research Database (Denmark)

2017-01-01

Ethicists have tended to treat the psychology of attributing mental states to animals as an entirely separate issue from the moral importance of animals’ mental states. In this paper I bring these two issues together. I argue for two theses, one descriptive and one normative. The descriptive thesis...... holds that ordinary human agents use what are generally called phenomenal mental states (e.g., pain and other emotions) to assign moral considerability to animals. I examine recent empirical research on the attribution of phenomenal states and agential states (e.g., memory and intelligence) to argue...... that phenomenal mental states are the primary factor, psychologically, for judging an animal to be morally considerable. I further argue that, given the role of phenomenal states in assigning moral considerability, certain theories in animal ethics will meet significant psychological resistance. The normative...

Animal welfare and the human-animal bond: considerations for veterinary faculty, students, and practitioners.

Science.gov (United States)

Wensley, Sean P

2008-01-01

Consideration of the human-animal bond typically focuses on the benefits of companion animals to human health and well-being, but it is essential that in realizing these benefits the welfare needs of the animals, both physical and mental, are also met. Positive emotional relationships with animals are likely to increase recognition of animal sentience and so help create positive attitudes toward animals at the societal level, but, at the individual level, the animals to which humans are bonded should also benefit from the human-animal relationship. A strong human-animal bond may benefit animal welfare (e.g., by motivating an owner to commit time and funds to necessary veterinary medical treatment), but may also be the source of compromised welfare. Highly bonded owners may, for example, be reluctant to permit euthanasia on humane grounds, and the anthropomorphic nature of many human-companion animal bonds can contribute to the development of problem behaviors and obesity. The challenge for the veterinary profession is to ensure that widespread positive sentiment toward animals, which the human-animal bond generates, is translated in to human behavior and actions that are conducive to good animal welfare. This, it is suggested, can be achieved through adequate veterinary education in veterinary and animal welfare science, ethics, and communication.

The development of an animal health barometer, an instrument to measure the general health of the Belgian livestock population on a yearly basis and to monitor its evolution over time, is described. The elaboration of a set of 13 animal health indicators (AHIs) as the basis for the animal health barometer is discussed. These indicators were weighted by experts - including scientists, policy makers and agro-industrial representatives - to determine their relative weight in the barometer. The result of the barometer is expressed as a comparison with a previous year. Based on the results of the 13 AHIs, it is concluded that general animal health in Belgium shows a positive evolution since 2008. The animal health barometer provides a composite view of the status of livestock health in Belgium and is a tool to communicate in an intelligible, comprehensible manner on aspects of animal health to consumers and professional stakeholders in the animal production and food chain. Together with the food safety barometer (Baert et al., 2011. Food Res. Int. 44, 940) and the plant health barometer (Wilmart et al., 2014. Eur. J. Plant Pathol. doi: 10.1007/s10658-014-0547-x), the animal health barometer is one of the three instruments to provide a holistic view on the overall status of the safety of the food chain in Belgium.

Gillette, E.L.

There are few trained veterinary radiation oncologists and the expense of facilities has limited the extent to which this modality is used. In recent years, a few cobalt teletherapy units and megavoltage x-ray units have been employed in larger veterinary institutions. In addition, some radiation oncologists of human medical institutions are interested and willing to cooperate with veterinarians in the treatment of animal tumors. Carefully designed studies of the response of animal tumors to new modalities serve two valuable purposes. First, these studies may lead to improved tumor control in companion animals. Second, these studies may have important implications to the improvement of therapy of human tumors. Much remains to be learned of animal tumor biology so that appropriate model systems can be described for such studies. Many of the latter studies can be sponsored by agencies interested in the improvement of cancer management

Animal cruelty is a known behavior of psychopaths, and although the serial killing of humans is widely acknowledged worldwide, this type of crime against animals is seldom discussed. This report describes the necropsy and toxicological findings of 37 dogs and cats, which were found dead in plastic bags in Sao Paulo, Brazil. The animals had all been in the care of an alleged animal rescuer and were to be referred for adoption before being found dead. In the necropsy, the animals showed varying degrees of putrefaction, indicating different periods of death, as well as single or multiple perforations on the thorax. The perforations reached the heart, lungs or large thoracic vessels, culminating in hemopericardium and hemothorax that led to death by circulatory failure and cardiac tamponade. Blood from the heart and thoracic cavity was analyzed by gas chromatography coupled with mass spectrometry (GC-MS) and tested positive for ketamine, a dissociative anesthetic. The suspect declared that she had killed only five of the animals and that they had all been fatally sick. The necropsy proved that all 37 animals were killed in the same way, that none of the animals had any terminal diseases and that a restricted drug was used. The suspect was sentenced to 12 years, 6 months and 14days of prison for the killing of the 37 animals. This was the first conviction for the crime of animal cruelty in Brazil. The combined role of police, forensic veterinary pathologists and prosecutors were essential to the conviction, which was a great historical occasion in the fight against animal cruelty.

For example, muscle frequencies in vivo are highly constrained by body size, which apparently tunes muscle use to maximize recovery of elastic recoil potential energy. Secondary to this constraint, there is an expected linking of skeletal muscle structural and functional properties. Muscle is relatively simple structurally, but by changing proportions of the few muscle components, a diverse range of functional outputs is possible. Thus, there is a consistent and predictable relation between muscle function and myocyte composition that illuminates animal locomotion. When animals move, the mechanical properties of muscle diverge from the static textbook force-velocity relations described by A. V. Hill, as recovery of elastic potential energy together with force and power enhancement with activation during stretch combine to modulate performance. These relations are best understood through the tool of work loops. Also, when animals move, locomotion is often conveniently categorized energetically. Burst locomotion is typified by high-power outputs and short durations while sustained, cyclic, locomotion engages a smaller fraction of the muscle tissue, yielding lower force and power. However, closer examination reveals that rather than a dichotomy, energetics of locomotion is a continuum. There is a remarkably predictable relationship between duration of activity and peak sustainable performance.

Indian draught animals power

Directory of Open Access Journals (Sweden)

K. L. Phaniraja

Full Text Available With the modernization of agriculture, the use of mechanical power in agriculture has increased but draught animal power (DAP continues to be used on Indian farms due to small holdings and hill agriculture. More than 55% of the total cultivated area is still being managed by using draught animals as against about 20% by tractors. India possessed the finest breeds of draught animals. Bullocks, buffaloes and camels are the major draught animals for field operations. Horses, mules, donkeys, yak and mithun are the pack animals for transport. The quality of work from the draught animals depends upon the power developed by them. The design of traditional implements is based on long experience and these have served the purpose of the farmers. However there is plenty of scope to improve the design based on animal-machine-environment interaction so as to have more output and increased efficiency without jeopardizing animal health.

Sketching with animation

DEFF Research Database (Denmark)

Vistisen, Peter

This book offers a contribution to the theory, method and techniques involved in the use of animation as a tool for temporal design sketching. Lifted from its traditional role as a genre of entertainment and art and reframed in the design domain, animation offers support during the early phases...... of exploring and assessing the potential of new and emerging digital technologies. This approach is relatively new and has been touched upon by few academic contributions in the past. Thus, the aim of the text is not to promote a claim that sketching with animation is an inherently new phenomenon. Instead......, the aim is to present a range of analytical arguments and experimental results that indicate the need for a systematic approach to realising the potential of animation within design sketching. This will establish the foundation for what we label animation-based sketching....

Full Text Available Exercício pode ser definido como um "estressor normal" estimulando as funções corpóreas. Alguns trabalhos sugerem o lactato como estimulador da secreção de cortisol , enquanto que a creatinina varia em função da quantidade de tecido muscular. No presente estudo é investigada a relação entre creatinina, lactato e cortisol séricos em cavalos em treinamento. Vinte e três potras Puro Sangue Inglês foram utilizadas, divididas em 3 grupos de acordo com a idade e protocolo de treinamento: G1, 1-2 anos de idade (n=7 mantidas a pasto, G2, 2-3 anos (n=9 começando a ser montadas e G3, 3-4 anos (n=7 competindo no Jockey Club. Amostras de sangue foram colhidas semanalmente durante 6 meses próximo às 13 h, enquanto os animais descansavam. O cortisol foi quantificado através de kits comerciais (Coat-a Count® e a creatinina sérica e o lactato foram avaliados através de um auto-analyzer, usando reagentes comerciais. Os resultados foram avaliados utilizando testes estatísticos não-paramétricos com nível de significância P<0,05. As concentrações de cortisol foram 149ª + 7, 126b + 6, e 101c + 5 nmol/l, as concentrações de lactato foram 2,1ª + 0,1, 2,0ª + 0,1, e 1,75b + 0,1 mmol/l, e as concentrações de creatinina foram 125ª + 2, 132ª + 2 145b + 3 mimol/l nos grupos G1, G2 e G3, respectivamente. Somente o G2 apresentou uma pequena, mas significante correlação positiva do cortisol com o lactato e correlação negativa do cortisol com a concentração de creatinina. Foi possível concluir que o cortisol, lactato e a creatinina variaram em função da idade e do condicionamento físico. A diminuição do cortisol observada nos animais do G2, reflete o melhor condicionamento físico adquirido durante o treinamento, que pode ser inferido através do aumento da concentração de creatinina, relacionada a quantidade de massa muscular. A diminuição do cortisol observada nos animais do G3 pode também ser conseqüência do aumento da

OBJECTIVE To explore the extent to which veterinary colleges and schools accredited by the AVMA Council on Education (COE) have incorporated specific courses related to animal welfare, behavior, and ethics. DESIGN Survey and curriculum review. SAMPLE All 49 AVMA COE-accredited veterinary colleges and schools (institutions). PROCEDURES The study consisted of 2 parts. In part 1, a survey regarding animal welfare, behavior, and ethics was emailed to the associate dean of academic affairs at all 49 AVMA COE-accredited institutions. In part 2, the curricula for the 30 AVMA COE-accredited institutions in the United States were reviewed for courses on animal behavior, ethics, and welfare. RESULTS Seventeen of 49 (35%) institutions responded to the survey of part 1, of which 10 offered a formal animal welfare course, 9 offered a formal animal behavior course, 8 offered a formal animal ethics course, and 5 offered a combined animal welfare, behavior, and ethics course. The frequency with which courses on animal welfare, behavior, and ethics were offered differed between international and US institutions. Review of the curricula for the 30 AVMA COE-accredited US institutions revealed that 6 offered a formal course on animal welfare, 22 offered a formal course on animal behavior, and 18 offered a formal course on animal ethics. CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that AVMA COE-accredited institutions need to provide more formal education on animal welfare, behavior, and ethics so veterinarians can be advocates for animals and assist with behavioral challenges.

Refining animal experiments: the first Brazilian regulation on animal experimentation.

Science.gov (United States)

de A e Tréz, Thales

2010-06-01

The very first law on animal experimentation has been approved recently in Brazil, and now is part of a set of the legal instruments that profile the Brazilian government's attitude toward the use of animals in experiments. Law 11794/08 establishes a new legal instrument that will guide new methods of conduct for ethics committees, researchers and representatives of animal protection societies. This comment aims to analyse critically the implications that this law brings to Brazilian reality. The link between it and the Russell and Burch's Three Rs concept is defined, and certain problems are identified. The conclusion is that the body of the law emphasises the refinement of animal experiments, but gives little importance to the principles of reduction and replacement.

Full Text Available A biotecnologia animal tem fornecido novas ferramentas para os programas de melhoramento e, dessa forma, contribuído para melhorar a eficiência da produção dos produtos de origem animal. No entanto, os avanços têm sido mais lentos do que antecipados, especialmente em razão da dificuldade na identificação dos genes responsáveis pelas características fenotípicas de interesse zootécnico. Três estratégias principais têm sido utilizadas para identificar esses genes - mapeamento de QTL, genes candidatos e sequenciamento de DNA e mRNA - e cada uma tem suas vantagens e limitações. O mapeamento de QTL permite determinar as regiões genômicas que contêm genes, mas o intervalo de confiança do QTL pode ser grande e conter muitos genes. A estratégia de genes candidatos é limitada por causa do conhecimento ainda restrito das funções de todos os genes. Os sequenciamentos de genomas e de sequências expressas podem auxiliar na identificação da posição de genes e de vias metabólicas associadas à característica de interesse. A integração dessas estratégias por meio do desenvolvimento de programas de bioinformática permitirá a identificação de novos genes de interesse zootécnico. Assim, os programas de melhoramento genético se beneficiarão pela inclusão da informação obtida diretamente do DNA na avaliação do mérito genético dos plantéis disponíveis.Animal biotechnology is providing new tools for animal breeding and genetics and thus contributing to advances in production efficiency and quality of animal products.

Animals In Synchrotrons: Overcoming Challenges For High-Resolution, Live, Small-Animal Imaging

International Nuclear Information System (INIS)

Donnelley, Martin; Parsons, David; Morgan, Kaye; Siu, Karen

2010-01-01

Physiological studies in small animals can be complicated, but the complexity is increased dramatically when performing live-animal synchrotron X-ray imaging studies. Our group has extensive experience in high-resolution live-animal imaging at the Japanese SPring-8 synchrotron, primarily examining airways in two-dimensions. These experiments normally image an area of 1.8 mmx1.2 mm at a pixel resolution of 0.45 μm and are performed with live, intact, anaesthetized mice.There are unique challenges in this experimental setting. Importantly, experiments must be performed in an isolated imaging hutch not specifically designed for small-animal imaging. This requires equipment adapted to remotely monitor animals, maintain their anesthesia, and deliver test substances while collecting images. The horizontal synchrotron X-ray beam has a fixed location and orientation that limits experimental flexibility. The extremely high resolution makes locating anatomical regions-of-interest slow and can result in a high radiation dose, and at this level of magnification small animal movements produce motion-artifacts that can render acquired images unusable. Here we describe our experimental techniques and how we have overcome several challenges involved in performing live mouse synchrotron imaging.Experiments have tested different mouse strains, with hairless strains minimizing overlying skin and hair artifacts. Different anesthetics have also be trialed due to the limited choices available at SPring-8. Tracheal-intubation methods have been refined and controlled-ventilation is now possible using a specialized small-animal ventilator. With appropriate animal restraint and respiratory-gating, motion-artifacts have been minimized. The animal orientation (supine vs. head-high) also appears to affect animal physiology, and can alter image quality. Our techniques and image quality at SPring-8 have dramatically improved and in the near future we plan to translate this experience to the

Simple Summary We studied different EU production standards and initiatives to determine whether there is still room or not for further animal welfare improvement, and which should be the best way to achieve it. Many of the adopted measures in these standards and initiatives are scientifically supported, but other aspects that are equally important for animal welfare are not included in any of them. Animal welfare improvement should consider, for each country, those aspects actually benefiting animals, but also the social expectations within each country. Economic constraints might explain the gap between what society demands, and what farm animals actually need. Abstract Information about animal welfare standards and initiatives from eight European countries was collected, grouped, and compared to EU welfare standards to detect those aspects beyond minimum welfare levels demanded by EU welfare legislation. Literature was reviewed to determine the scientific relevance of standards and initiatives, and those aspects going beyond minimum EU standards. Standards and initiatives were assessed to determine their strengths and weaknesses regarding animal welfare. Attitudes of stakeholders in the improvement of animal welfare were determined through a Policy Delphi exercise. Social perception of animal welfare, economic implications of upraising welfare levels, and differences between countries were considered. Literature review revealed that on-farm space allowance, climate control, and environmental enrichment are relevant for all animal categories. Experts’ assessment revealed that on-farm prevention of thermal stress, air quality, and races and passageways’ design were not sufficiently included. Stakeholders considered that housing conditions are particularly relevant regarding animal welfare, and that animal-based and farm-level indicators are fundamental to monitor the progress of animal welfare. The most notable differences between what society offers and what

Full Text Available Previous data suggest that Salvador, the capital of the State of Bahia, a northeastern state of Brazil, has the highest prevalence of HTLV infection in blood donors among Brazilian cities. The aim of this case-control study was to identify the determinants of risk for HTLV infection among blood donors in the city of Salvador. Between January 2000 and December 2003, 504 blood donors with positive screening tests for HTLV infection (unconfirmed prevalence of 0.48% were invited to participate in our study. A total of 154 had performed a Western Blot (WB test, 139 were of which found to be positive (false positive screening rate 9.9%. Using a standardized questionnaire, a single interviewer obtained information on demographic, socio-economical and educational characteristics, as well as sexual behavior from 91 out of the 139 positive by WB and from 194 HTLV-negative blood donors. Prevalence of HTLV infection was 0.48%. Multivariate analysis revealed women (OR 3.79 [1.61-8.88], p=0.002, low family income* (OR 3.37 [1.17-9.66], p=0.02, self-reported history of sexual transmitted diseases (OR 6.15 [2.04-18.51], p=0.001, 2 or more sexual partners during life (OR 9.29 [2.16-39.94], p=0.0020 and inconsistent use of condoms (OR 4.73 [1.98-11.26], p=0.0004 as risk factors for HTLV infection. In accordance with previous published data, our results point to an association between low socio-economical level, poor education and unsafe sexual behavior with HTLV infection. We observed a lower prevalence of HLTV infection when compared to previous data.Estudos anteriores sugerem que Salvador, capital da Bahia, um estado do Nordeste do Brasil, tem a maior prevalência de infecção por HTLV em doadores de sangue entre as cidades brasileiras.

Animal behavior and well-being symposium: Farm animal welfare assurance: science and application.

Science.gov (United States)

Rushen, J; Butterworth, A; Swanson, J C

Public and consumer pressure for assurances that farm animals are raised humanely has led to a range of private and public animal welfare standards, and for methods to assess compliance with these standards. The standards usually claim to be science based, but even though researchers have developed measures of animal welfare and have tested the effects of housing and management variables on welfare within controlled laboratory settings, there are challenges in extending this research to develop on-site animal welfare standards. The standards need to be validated against a definition of welfare that has broad support and which is amenable to scientific investigation. Ensuring that such standards acknowledge scientific uncertainty is also challenging, and balanced input from all scientific disciplines dealing with animal welfare is needed. Agencies providing animal welfare audit services need to integrate these scientific standards and legal requirements into successful programs that effectively measure and objectively report compliance. On-farm assessment of animal welfare requires a combination of animal-based measures to assess the actual state of welfare and resource-based measures to identify risk factors. We illustrate this by referring to a method of assessing welfare in broiler flocks. Compliance with animal welfare standards requires buy-in from all stakeholders, and this will be best achieved by a process of inclusion in the development of pragmatic assessment methods and the development of audit programs verifying the conditions and continuous improvement of farm animal welfare.

Animal models of pancreatitis are useful for elucidating the pathogenesis of pancreatitis and developing and testing novel interventions. In this review, we aim to summarize the most commonly used animal models, overview their pathophysiology, and discuss their strengths and limitations. We will also briefly describe common animal study procedures and refer readers to more detailed protocols in the literature. Although animal models include pigs, dogs, opossums, and other animals, we will mainly focus on rodent models because of their popularity. Autoimmune pancreatitis and genetically engineered animal models will be reviewed elsewhere. PMID:27418683

ANIMALS IN RESOCIALIZATION

OpenAIRE

Czerw, Monika

2017-01-01

The benefits of relations between humans and animals have encouraged both scientists and members of other communities to popularize the knowledge in the field of animal-assisted therapy. Currently, animal-assisted therapy has been used not only in therapy, but also in resocialization. The increasing popularity of this form of supporting maladjusted people who are isolated from society or people with disabilities encouraged both practitioners and researchers to organize knowledge, thus reducin...

One of the limitations of this screening is the immunological window, a period that may contribute to the transfusion of contaminated blood. The aim of this study was to evaluate self-exclusion rates related to age, gender, marital status, race, type of donation, annual variations in self-exclusion and the efficacy of self-exclusion to prevent the transfusion of contaminated blood. A retrospective study was conducted and the data were analyzed using the chi-square test, odds ratio and linear regression. Of the 176,097 blood bags collected at the Uberaba Regional Blood Center (HRU between 1996 and 2006, 2.72% were discarded due to self-exclusion. There was a predominance of first-time, unmarried, non-white male donors over the age of 29 years old (p<0.0001. An inverse association was observed between long-term commitment and self-exclusion, suggesting that the higher the return rate, the lower the incidence of self-exclusion. Positive serology for HIV1 (0.35% and HIV2 (0.23% was significantly higher among self-exclusion donors

Free the animals? Investigating attitudes toward animal testing in Britain and the United States.

Science.gov (United States)

Swami, Viren; Furnham, Adrian; Christopher, Andrew N

2008-06-01

In this study, 185 British and 143 American undergraduates completed a battery of tests that measured attitudes toward animal testing and various individual difference variables. Attitudes toward animal testing factored into two interpretable factors: general attitudes toward animal testing, and animal welfare and conditions of testing. Overall, there was support for animal testing under the right conditions, although there was also concern for the welfare of animals and the conditions under which testing takes place. There were small but significant national difference on both factors (with Americans more positive about testing and less positive about animal welfare), and a significant sex difference on the first factor (women were more negative about testing). Correlation and regression analyses showed that there were few significant individual difference predictors of both factors. These results are discussed in relation to past and future work on attitudes toward animal testing.

Principles of animal extrapolation

Energy Technology Data Exchange (ETDEWEB)

Calabrese, E.J.

1991-01-01

Animal Extrapolation presents a comprehensive examination of the scientific issues involved in extrapolating results of animal experiments to human response. This text attempts to present a comprehensive synthesis and analysis of the host of biomedical and toxicological studies of interspecies extrapolation. Calabrese's work presents not only the conceptual basis of interspecies extrapolation, but also illustrates how these principles may be better used in selection of animal experimentation models and in the interpretation of animal experimental results. The book's theme centers around four types of extrapolation: (1) from average animal model to the average human; (2) from small animals to large ones; (3) from high-risk animal to the high risk human; and (4) from high doses of exposure to lower, more realistic, doses. Calabrese attacks the issues of interspecies extrapolation by dealing individually with the factors which contribute to interspecies variability: differences in absorption, intestinal flora, tissue distribution, metabolism, repair mechanisms, and excretion. From this foundation, Calabrese then discusses the heterogeneticity of these same factors in the human population in an attempt to evaluate the representativeness of various animal models in light of interindividual variations. In addition to discussing the question of suitable animal models for specific high-risk groups and specific toxicological endpoints, the author also examines extrapolation questions related to the use of short-term tests to predict long-term human carcinogenicity and birth defects. The book is comprehensive in scope and specific in detail; for those environmental health professions seeking to understand the toxicological models which underlay health risk assessments, Animal Extrapolation is a valuable information source.

Animals as disgust elicitors

DEFF Research Database (Denmark)

Kasperbauer, Tyler Joshua

2015-01-01

This paper attempts to explain how and why nonhuman animals elicit disgust in human beings. I argue that animals elicit disgust in two ways. One is by triggering disease–protection mechanisms, and the other is by eliciting mortality salience, or thoughts of death. I discuss how these two types...... of disgust operate and defend their conceptual and theoretical coherence against common objections. I also outline an explanatory challenge for disgust researchers. Both types of disgust indicate that a wide variety of animals produce aversive and avoidant reactions in human beings. This seems somewhat odd......, given the prominence of animals in human lives. The challenge, then, is explaining how humans cope with the presence of animals. I propose, as a hypothesis for further exploration, that we cope with animals, and our disgust responses to them, by attributing mental states that mark them as inferior...

The Effect of Steps to Promote Higher Levels of Farm Animal Welfare across the EU. Societal versus Animal Scientists' Perceptions of Animal Welfare.

Science.gov (United States)

Averós, Xavier; Aparicio, Miguel A; Ferrari, Paolo; Guy, Jonathan H; Hubbard, Carmen; Schmid, Otto; Ilieski, Vlatko; Spoolder, Hans A M

2013-08-14

Information about animal welfare standards and initiatives from eight European countries was collected, grouped, and compared to EU welfare standards to detect those aspects beyond minimum welfare levels demanded by EU welfare legislation. Literature was reviewed to determine the scientific relevance of standards and initiatives, and those aspects going beyond minimum EU standards. Standards and initiatives were assessed to determine their strengths and weaknesses regarding animal welfare. Attitudes of stakeholders in the improvement of animal welfare were determined through a Policy Delphi exercise. Social perception of animal welfare, economic implications of upraising welfare levels, and differences between countries were considered. Literature review revealed that on-farm space allowance, climate control, and environmental enrichment are relevant for all animal categories. Experts' assessment revealed that on-farm prevention of thermal stress, air quality, and races and passageways' design were not sufficiently included. Stakeholders considered that housing conditions are particularly relevant regarding animal welfare, and that animal-based and farm-level indicators are fundamental to monitor the progress of animal welfare. The most notable differences between what society offers and what farm animals are likely to need are related to transportation and space availability, with economic constraints being the most plausible explanation.

This chapter aims to encourage scientists and others interested in the use of animal models of disease – specifically, in the study of dementia – to engage in ethical reflection. It opens with a general discussion of the moral acceptability of animal use in research. Three ethical approaches...... are here distinguished. These serve as points of orientation in the following discussion of four more specific ethical questions: Does animal species matter? How effective is disease modelling in delivering the benefits claimed for it? What can be done to minimize potential harm to animals in research? Who...... bears responsibility for the use of animals in disease models?...

Can experiments on animals constitute a criminal offence of cruelty to animals?

Directory of Open Access Journals (Sweden)

Ristivojevic Branislav

2014-01-01

Full Text Available The criminal offence “killing and torturing animals” under Article 269 of the Criminal Code says that it can be committed only “contrary to regulations”. The regulations governing the treatment of experimental animals are the Animal Welfare Law from 2009 and the Law on the Ratification of the European Convention for the Protection of Vertebrate Animals used for experimental and other scientific purposes amended by the Protocol of amendment to the European Convention for the Protection of Vertebrate Animals used for experimental and other scientific purposes from 2010. The first one imposes numerous obligations and introduces numerous prohibitions in the treatment of experimental animals, which at first sight make the possibilities of committing this criminal offence greater. The other law does not contain most of the prohibitions and restrictions that are included in the Animal Welfare Law. Thanks to a legal rule which says that a later law regulating the same subject replaces the former one (lex posterior derogate legi priori and the aforementioned unconstitutionality of many provisions of the Animal Welfare Law, researchers and teachers in Serbia are not in particular danger of criminal prosecution.

Medication of Production Animals – Cure of Malfunctioning Animals or Production Systems?

Directory of Open Access Journals (Sweden)

Chrièl Mariann

2003-03-01

Full Text Available Medication is used in all intensive animal productions. However, the increasing problems with resistant bacteria in all animal productions and in humans are supported by a number of reports. Special attention is given to the risk for transmitting food-borne (multi resistant zoonotic agents to humans due to failure in antibiotic treatment resulting in lower cure rates or higher case fatality rates. The use of medication in humans per se is capable of selecting for resistance in human pathogens. Nevertheless, the amount of used medication/antimicrobials in treatment of Danish production animals goes far beyond the amount used for human consumption. The increase in consumption has not been followed by a similarly increased mortality, e.g. illustrated by the number of rendered animals, increased use of injection medicine for veterinary treatments of diseased animals, or increased number of remarks on the carcasses from the slaughterhouses. Medication in animal production is facing its limits and relevant economic alternatives have to be developed. The strategy for the future must concentrate on using medication only for clinically diseased animals and not as a strategic treatment of the whole herd in order to maximise growth and camouflage of suboptimal production systems and insufficient management.

[Dignity or integrity - does the genetic modification of animals require new concepts in animal ethics?].

Science.gov (United States)

Schmidt, Kirsten

2008-01-01

Animal genetic engineering seems to point at a normative gap beyond pathocentric welfare theories in animal ethics. Recently developed approaches aim to bridge this gap by means of new normative criteria such as animal dignity and animal integrity. The following comparison of dignity and integrity in the context of animal ethics shows that the dignity concept faces serious problems because of its necessarily anthroporelational character and the different functions of contingent and inherent dignity within ethical reasoning. Unlike animal dignity the concept of animal integrity could prove to be a useful enhancement for pathocentric approaches.

Companion animals comprise a wide variety of species, including dogs, cats, horses, ferrets, guinea pigs, reptiles, birds and ornamental fish, as well as food production animal species, such as domestic pigs, kept as companion animals. Despite their prominent place in human society, little is known about the role of companion animals as sources of viruses for people and food production animals. Therefore, we reviewed the literature for accounts of infections of companion animals by zoonotic viruses and viruses of food production animals, and prioritized these viruses in terms of human health and economic importance. In total, 138 virus species reportedly capable of infecting companion animals were of concern for human and food production animal health: 59 of these viruses were infectious for human beings, 135 were infectious for food production mammals and birds, and 22 were infectious for food production fishes. Viruses of highest concern for human health included hantaviruses, Tahyna virus, rabies virus, West Nile virus, tick-borne encephalitis virus, Crimean-Congo haemorrhagic fever virus, Aichi virus, European bat lyssavirus, hepatitis E virus, cowpox virus, G5 rotavirus, influenza A virus and lymphocytic choriomeningitis virus. Viruses of highest concern for food production mammals and birds included bluetongue virus, African swine fever virus, foot-and-mouth disease virus, lumpy skin disease virus, Rift Valley fever virus, porcine circovirus, classical swine fever virus, equine herpesvirus 9, peste des petits ruminants virus and equine infectious anaemia virus. Viruses of highest concern for food production fishes included cyprinid herpesvirus 3 (koi herpesvirus), viral haemorrhagic septicaemia virus and infectious pancreatic necrosis virus. Of particular concern as sources of zoonotic or food production animal viruses were domestic carnivores, rodents and food production animals kept as companion animals.

Pursuing an understanding of animal consciousness: Implications for animal morality and a creaturely theology

Directory of Open Access Journals (Sweden)

Cornel W. du Toit

2015-07-01

Full Text Available The importance of animals in the evolutionary history of homo sapiens comes to the fore in light of an increasingly trans-human techno-scientific environment. New research on consciousness, and animal consciousness in particular, has prompted questions relating to animal rights, animal morality and the emergence of a creaturely theology and theological primatology. The possibility of understanding nonhuman animals is investigated with reference to notions like consciousness, thinking, awareness, language and communication, including the importance of emotion in communication. Special attention is given to the nature of animal communication as it came to the fore in bonobo and other chimpanzee research. Building on the notion of awareness and communication, the article focuses on the notion of animal morality and comments on some aspects of a creaturely theology.

Gaughan, John B.; Lees, Angela M.; Sejian, Veerasamy

2017-10-01

Animal biometeorology (insects excluded) has been part of the International Journal of Biometeorology since its inception in 1958. Over the first 60 years of the journal, 480 animal biometeorology papers were published. Thus, approximately 14% of published papers dealt with animals. Over the first 60 years, data from more than 50 animal species was presented, with the lead authors coming from 48 countries. The two most common species used in animal papers between 1957 and 2016 were cattle (109 papers: 22.7% of all animal papers) and rats (96 papers: 20.0% of all animal papers). Although cattle and rats dominated, the species in the most cited paper (240 citations) was chickens, followed by bird migration (155 citations), and general livestock (118 citations). Overall, five papers exceeded 100 citations, and a further two exceeded 200 citations. In the last decade, 126 animal papers were published (26% of all animal papers). Many of these papers had a focus on livestock production in developing countries especially Brazil.

The chapter evaluates results of toxicological studies on experimental animals to investigate health effects of air pollutants and examines the animal data have predicted the response to human subject. Data are presented on the comparative toxicity of sulfur dioxide and sulfuric acid. The animal data obtained by measurement of airway resistance in guinea pigs and of bronchial clearance of particles in donkeys predicted clearly that sulfuric acid was more irritant than sulfur dioxide. Data obtained on human subjects confirmed this prediction. These acute studies also correctly predicted the comparative toxicity of the two compounds in two year studies of monkeys. Such chronic studies are not possible in human subjects but it is a reasonable to assume that sulfuric acid would be more toxic than sulfur dioxide. Current findings in epidemiological studies certainly support this assumption.

The prevalence of HCV-RNA positive individuals was compared with the recombinant immunoblot assay (RIBA-2 results in order to assess the usefulness of both tests as confirmatory assays. Both tests results were also compared with the EIA-2 OD/C ratio (optical densities of the samples divided by the cut off value. ALT results were expressed as the ALT quotient (qALT, calculated dividing the ALT value of the samples by the maximum normal value (53UI/l for the method. Donors (n=178 were divided into five groups according to their EIA anti-HCV status and qALT: group A (EIA > or = 3, ALT or = 3, ALT>1, group C (11 and group E (EIA or = 3 and detectable HCV-RNA by RT-nested PCR. We have also noted that blood donors with RIBA-2 indeterminate presented a high degree of detectable HCV-RNA using RT-nested PCR (75%, especially when the c22.3 band was detected.Na prevenção da transmissão de Hepatite por Vírus C (HCV em transfusões de hemocomponentes, utiliza-se rotineiramente, como testes de triagem de doadores de sangue, ensaios que detectam anticorpos anti-HCV e dosagens da enzima alanina-aminotransferase (ALT.

blood ingested and the fecundity were differents according to alternation of blood sources offered in each meal. A linear relation was found between the fecundity and the time of oviposition in every alternation of meal sources. On the other hand there was a slope increase in the second feeding of every experiment. The fertility was above 95% in each experiment. Efeito da alternação de fontes sanguíneas sobre fecundidade e fertilidade de Rhodnius prolixus Stal (Heteroptera ReduviidaeNeste trabalho evidencia-se que o sucesso reprodutivo de Rhodnius prolixus Stal esta relacionado à fonte alimentícia, então as necessidades biológicas do inseto são satisfeitas em modos diferentes segundo o tipo de alternância entre ditas fontes de alimentação; tais diferenças são reveladas mediante mudanças em fertilidade e fecundidade do inseto. Realizaram-se nove testes, em cada um foram subministradas duas alimentações, sendo que em alguns foi alternada a fonte de alimentação e nos controles foram subministradas duas alimentações com a mesma fonte. As fontes alimentícias foram pomba, galinha e humano, esta ultima mediante um aparelho de alimentação artificial; estas fontes foram escolhidas no suposto que são fontes alimentícias encontradas nos ecótopos silvestres, peridomicilio e domicilio respectivamente. Em todos os tipos de alternância foi encontrada uma relação lineal entre a fecundidade e o tempo de oviposição, que a relação entre quantidade de sangue ingerida e a fecundidade variam, que a taxa de fecundidade aumenta na segunda alimentação respeito à primeira e que a fertilidade foi superior ao 95%.

Dez ratos e dez camundongos foram alocados em quatro grupos iguais A e B (ratos, C e D (camundongos. Os grupos A e C receberam sangue contaminado de um rato e o grupo B e D de um camundongo, através de uma sonda. O volume de sangue administrado foi de 0,2ml, o qual apresentava uma concentração de 10(7 tripanossomas ml-1. Os animais foram mantidos em temperatura e umidade constantes (25°C e 80% UR, sendo realizados esfregaços sanguíneos diários para identificar o período pré-patente e a evolução do parasita na circulação. Nos grupos A e B, o período pré-patente variou de 19 a 25 dias, e o período entre a detecção dos parasitas e a morte dos animais foi em média de 12,7 dias. Os camundongos do grupo C e D não apresentaram infecção pelo parasita, sendo estes avaliados por 60 dias. Os ratos foram susceptíveis a infecção por T. evansi pela via oral; entretanto, os camundongos não se contaminaram com o protozoário por via digestiva.In this research, Trypanosoma evansi infection was tested in rats and mice by oral ingestion of contaminated blood. Groups of ten rats and ten mice were disposed in four experimental groups: A and B (rats, C and D (mice. The groups A and C were contaminated by rat-contaminated blood; B and C groups by mouse-contaminated blood. The blood was given using a probe filled with 0.2ml of contaminated blood with 10(7 trypanosomes ml-1. These animals were maintained at constant temperature and humidity (25°C and 80% UR. Dairy blood smear were done to identify the prepatent period and evolution of parasite in the circulation. In the A and B groups, the pre latency period varied from 19 to 25 days and the period of parasite detection and animals death was an average of 12.7 days. The C and D groups did not present infection by the parasite even when evaluated for 60 days

Draught animals and welfare.

Science.gov (United States)

Ramaswamy, N S

1994-03-01

In fifty developing countries, which contain half of the total human population of the world, there is a heavy dependence on draught animals as an energy source. These animals are used for agriculture operations in 52% of cultivated areas of the world, as well as for hauling 25 million carts. This situation is likely to continue for at least another fifty years. The work performed annually by these draught animals would require 20 million tons of petroleum, valued at US$6 billion, if it were performed by motorized vehicles. The poor working conditions of these animals often adversely affect their productivity. The application of improved technology and better management (i.e. through better feed and health services, and improved design of agricultural implements and carts) could considerably improve the welfare of these animals. Improved systems would generate sufficient benefits for the economy to justify the required investment. High priority should therefore be given to draught animal power in the economic development agenda.

Full Text Available A identificação do impacto que certas formas de estresse causam ao bem estar animal e equilíbrio orgânico, representa um desafio á adoção de boas práticas de criação. Assim, a presente pesquisa verificou o impacto de um desafio doloroso rotineiro dos bovinos na imunidade pulmonar e sistêmica. Avaliou-se hemograma e cortisol, em quatro momentos, sendo M1, M6, M7 e M8 (respectivamente sete dias antes e um, três e oito dias depois do desafio doloroso e citologia broncolaveolar, obtida por broncoscopia, nos momentos M1, M6 e M8. Houve uma redução dos valores do eritrograma no primeiro dia após o desafio, compatível com anaplasmose e agravada pela perda de sangue durante a cirurgia e um influxo de leucócitos para a região pulmonar. Oito dias após o desafio, evidenciou-se aumento de cortisol, gerando uma leucocitose por neutrofilia e monocitose no sangue com provável redução de quimiotaxia para o pulmão, tornando o trato respiratório potencialmente mais susceptível a infecções, sugerindo que esta prática de manejo, mesmo acompanhado de protocolo analgésico, pode ser considerada um fator de risco a penumonias afetando o bem estar animal.

Sound at the zoo: Using animal monitoring, sound measurement, and noise reduction in zoo animal management.

Orban, David A; Soltis, Joseph; Perkins, Lori; Mellen, Jill D

2017-05-01

A clear need for evidence-based animal management in zoos and aquariums has been expressed by industry leaders. Here, we show how individual animal welfare monitoring can be combined with measurement of environmental conditions to inform science-based animal management decisions. Over the last several years, Disney's Animal Kingdom® has been undergoing significant construction and exhibit renovation, warranting institution-wide animal welfare monitoring. Animal care and science staff developed a model that tracked animal keepers' daily assessments of an animal's physical health, behavior, and responses to husbandry activity; these data were matched to different external stimuli and environmental conditions, including sound levels. A case study of a female giant anteater and her environment is presented to illustrate how this process worked. Associated with this case, several sound-reducing barriers were tested for efficacy in mitigating sound. Integrating daily animal welfare assessment with environmental monitoring can lead to a better understanding of animals and their sensory environment and positively impact animal welfare. © 2017 Wiley Periodicals, Inc.

Ethical issues in animal cloning.

Science.gov (United States)

Fiester, Autumn

2005-01-01

The issue of human reproductive cloning has recently received a great deal attention in public discourse. Bioethicists, policy makers, and the media have been quick to identify the key ethical issues involved in human reproductive cloning and to argue, almost unanimously, for an international ban on such attempts. Meanwhile, scientists have proceeded with extensive research agendas in the cloning of animals. Despite this research, there has been little public discussion of the ethical issues raised by animal cloning projects. Polling data show that the public is decidedly against the cloning of animals. To understand the public's reaction and fill the void of reasoned debate about the issue, we need to review the possible objections to animal cloning and assess the merits of the anti-animal cloning stance. Some objections to animal cloning (e.g., the impact of cloning on the population of unwanted animals) can be easily addressed, while others (e.g., the health of cloned animals) require more serious attention by the public and policy makers.

Phylogenomic Insights into Animal Evolution.

Telford, Maximilian J; Budd, Graham E; Philippe, Hervé

2015-10-05

Animals make up only a small fraction of the eukaryotic tree of life, yet, from our vantage point as members of the animal kingdom, the evolution of the bewildering diversity of animal forms is endlessly fascinating. In the century following the publication of Darwin's Origin of Species, hypotheses regarding the evolution of the major branches of the animal kingdom - their relationships to each other and the evolution of their body plans - was based on a consideration of the morphological and developmental characteristics of the different animal groups. This morphology-based approach had many successes but important aspects of the evolutionary tree remained disputed. In the past three decades, molecular data, most obviously primary sequences of DNA and proteins, have provided an estimate of animal phylogeny largely independent of the morphological evolution we would ultimately like to understand. The molecular tree that has evolved over the past three decades has drastically altered our view of animal phylogeny and many aspects of the tree are no longer contentious. The focus of molecular studies on relationships between animal groups means, however, that the discipline has become somewhat divorced from the underlying biology and from the morphological characteristics whose evolution we aim to understand. Here, we consider what we currently know of animal phylogeny; what aspects we are still uncertain about and what our improved understanding of animal phylogeny can tell us about the evolution of the great diversity of animal life.

Is animal experimentation fundamental?

d'Acampora, Armando José; Rossi, Lucas Félix; Ely, Jorge Bins; de Vasconcellos, Zulmar Acciolli

2009-01-01

The understanding about the utilization of experimental animals in scientific research and in teaching is many times a complex issue. Special attention needs to be paid to attain the understanding by the general public of the importance of animal experimentation in experimental research and in undergraduate medical teaching. Experimental teaching and research based on the availability of animals for experimentation is important and necessary for the personal and scientific development of the physician-to-be. The technological arsenal which intends to mimic experimentation animals and thus fully replace their use many times does not prove to be compatible with the reality of the living animal. The purpose of this paper is to discuss aspects concerning this topic, bringing up an issue which is complex and likely to arouse in-depth reflections.

Full Text Available A focused and commented review on the impact of dermatologic diseases and interventions in the solidary act of donating blood is presented to dermatologists to better advise their patients. This is a review of current Brazilian technical regulations on hemotherapeutic procedures as determined by Ministerial Directive #1353/2011 by the Ministry of Health and current internal regulations of the Hemotherapy Center of Ribeirão Preto, a regional reference center in hemotherapeutic procedures. Criteria for permanent inaptitude: autoimmune diseases (>1 organ involved, personal history of cancer other than basal cell carcinoma, severe atopic dermatitis or psoriasis, pemphigus foliaceus, porphyrias, filariasis, leprosy, extra pulmonary tuberculosis or paracoccidioidomycosis, and previous use of etretinate. Drugs that impose temporary ineligibility: other systemic retinoids, systemic corticosteroids, 5-alpha-reductase inhibitors, vaccines, methotrexate, beta-blockers, minoxidil, anti-epileptic, and anti-psychotic drugs. Other conditions that impose temporary ineligibility: occupational accident with biologic material, piercing, tattoo, sexually transmitted diseases, herpes, and bacterial infections, among others. Discussion: Thalidomide is currently missing in the teratogenic drugs list. Although finasteride was previously considered a drug that imposed permanent inaptitude, according to its short halflife current restriction of 1 month is still too long. Dermatologists should be able to advise their patients about proper timing to donate blood, and discuss the impact of drug withdrawal on treatment outcomes and to respect the designated washout periods.Uma revisão centrada no impacto de doenças e intervenções dermatológicas no ato solidário de doar sangue é apresentada aos dermatologistas para melhor aconselhamento dos seus pacientes.

Aquatic animals are the most popular pets in the United States based on the number of owned pets. They are popular display animals and are increasingly used in research settings. Enrichment of captive animals is an important element of zoo and laboratory medicine. The importance of enrichment for aquatic animals has been slower in implementation. For a long time, there was debate over whether or not fish were able to experience pain or form long-term memories. As that debate has reduced and the consciousness of more aquatic animals is accepted, the need to discuss enrichment for these animals has increased. Copyright © 2015 Elsevier Inc.

Ethical and Animal Welfare Considerations in Relation to Species Selection for Animal Experimentation.

Science.gov (United States)

Webster, John

2014-12-03

Ethical principles governing the conduct of experiments with animals are reviewed, especially those relating to the choice of species. Legislation requires that the potential harm to animals arising from any procedure should be assessed in advance and justified in terms of its possible benefit to society. Potential harms may arise both from the procedures and the quality of the animals' lifetime experience. The conventional approach to species selection is to use animals with the "lowest degree of neurophysiological sensitivity". However; this concept should be applied with extreme caution in the light of new knowledge. The capacity to experience pain may be similar in mammals, birds and fish. The capacity to suffer from fear is governed more by sentience than cognitive ability, so it cannot be assumed that rodents or farm animals suffer less than dogs or primates. I suggest that it is unethical to base the choice of species for animal experimentation simply on the basis that it will cause less distress within society. A set of responsibilities is outlined for each category of moral agent. These include regulators, operators directly concerned with the conduct of scientific experiments and toxicology trials, veterinarians and animal care staff; and society at large.

Full Text Available The aim of the paper was to investigate the influence some factors on the consumers’ opinion regarding the animal welfare labelling of animal products. The analysed question was: “When purchasing eggs, meat or milk can you easily identify from the label those products sourced from animal welfare friendly production systems?” Respondents chosen only one answer out of the five offered: yes, most of the time; yes, some of the time; no, very rarely; no, never; and don’t know. Thirty three percent of females considered they could find sometime information regarding the animal welfare on the labels, while males considered that this information could be found very rarely. Up to 55 years of age, 50% of the consumers consider that the labels do not contain the information about animal welfare, while after this age most of consumers consider they found this information on the labels. Over 50% of Orthodox and Roman Catholic responders considered that the information on animal welfare on the labels was found some of the time or very rarely. Respondents, irrespective of their living area or monthly income, considered that there is scarce information regarding animal welfare on the labels. Internet access significantly influenced the consumers regarding the availability of the information on the labels.

Scientific assessment of animal welfare.

Science.gov (United States)

Hemsworth, P H; Mellor, D J; Cronin, G M; Tilbrook, A J

2015-01-01

Animal welfare is a state within the animal and a scientific perspective provides methodologies for evidence-based assessment of an animal's welfare. A simplistic definition of animal welfare might be how the animal feels now. Affective experiences including emotions, are subjective states so cannot be measured directly in animals, but there are informative indirect physiological and behavioural indices that can be cautiously used to interpret such experiences. This review enunciates several key science-based frameworks for understanding animal welfare. The biological functioning and affective state frameworks were initially seen as competing, but a recent more unified approach is that biological functioning is taken to include affective experiences and affective experiences are recognised as products of biological functioning, and knowledge of the dynamic interactions between the two is considered to be fundamental to managing and improving animal welfare. The value of these two frameworks in understanding the welfare of group-housed sows is reviewed. The majority of studies of the welfare of group-housed sows have employed the biological functioning framework to infer compromised sow welfare, on the basis that suboptimal biological functioning accompanies negative affective states such as sow hunger, pain, fear, helplessness, frustration and anger. Group housing facilitates social living, but group housing of gestating sows raises different welfare considerations to stall housing, such as high levels of aggression, injuries and stress, at least for several days after mixing, as well as subordinate sows being underfed due to competition at feeding. This paper highlights the challenges and potential opportunities for the continued improvement in sow management through well-focused research and multidisciplinary assessment of animal welfare. In future the management of sentient animals will require the promotion of positive affective experiences in animals and this

Animal transportation networks

Science.gov (United States)

Perna, Andrea; Latty, Tanya

2014-01-01

Many group-living animals construct transportation networks of trails, galleries and burrows by modifying the environment to facilitate faster, safer or more efficient movement. Animal transportation networks can have direct influences on the fitness of individuals, whereas the shape and structure of transportation networks can influence community dynamics by facilitating contacts between different individuals and species. In this review, we discuss three key areas in the study of animal transportation networks: the topological properties of networks, network morphogenesis and growth, and the behaviour of network users. We present a brief primer on elements of network theory, and then discuss the different ways in which animal groups deal with the fundamental trade-off between the competing network properties of travel efficiency, robustness and infrastructure cost. We consider how the behaviour of network users can impact network efficiency, and call for studies that integrate both network topology and user behaviour. We finish with a prospectus for future research. PMID:25165598

Radioactivity transfer to animal products

International Nuclear Information System (INIS)

Coughtrey, P.J.

1990-01-01

Information on the behaviour of strontium, caesium, ruthenium, plutonium and americium in a range of domestic animals is reviewed to form a basis for the specification of time-dependent mathematical models describing uptake, distribution and retention in various domestic animals. Transfer factors relating concentration in animal product to daily radioactivity intake are derived after 100 d continuous intake and at equilibrium. These transfer factors are compared with the available published literature and used as a basis for the derivation of feedingstuff conversion factors relating limiting concentrations in animal feedingstuffs to limiting concentrations in human foodstuffs for application to animals receiving commercial feedingstuffs after a nuclear accident. Recommended transfer factors for animal products in conditions of continuous discharge and models for application to field conditions after a nuclear accident are also presented. Transfer of caesium to animal products is more effective than that for the other elements considered here. Transfer to meat of lamb, fattening pig, and chickens is generally more effective than that for other animals and other products

Institutional transparency improves public perception of lab animal technicians and support for animal research.

Mills, Katelyn E; Han, Zetta; Robbins, Jesse; Weary, Daniel M

2018-01-01

The use of animals in research is controversial and often takes place under a veil of secrecy. Lab animal technicians responsible for the care of animals at research institutions are sometimes described as performing 'dirty work' (i.e. professions that are viewed as morally tainted), and may be stigmatized by negative perceptions of their job. This study assessed if transparency affects public perceptions of lab animal technicians and support for animal research. Participants (n = 550) were randomly assigned to one of six scenarios (using a 3x2 design) that described identical research varying only the transparency of the facility (low, high) and the species used (mice, dogs, cows). Participants provided Likert-type and open-ended responses to questions about the personal characteristics (warmth, competence) of a hypothetical lab technician 'Cathy' and their support for the described research. Quantitative analysis showed participants in the low-transparency condition perceived Cathy to be less warm and were less supportive of the research regardless of animal species. Qualitative responses varied greatly, with some participants expressing support for both Cathy and the research. These results suggest that increasing transparency in lab animal institutions could result in a more positive perception of lab animal researchers and the work that they do.

[Ethical issue in animal experimentation].

Science.gov (United States)

Parodi, André-Laurent

2009-11-01

In the 1970s, under pressure from certain sections of society and thanks to initiatives by several scientific research teams, committees charged with improving the conditions of laboratory animals started to be created, first in the United States and subsequently in Europe. This led to the development of an ethical approach to animal experimentation, taking into account new scientific advances. In addition to the legislation designed to provide a legal framework for animal experimentation and to avoid abuses, this ethical approach, based on the concept that animals are sentient beings, encourages greater respect of laboratory animals and the implementation of measures designed to reduce their suffering. Now, all animal experiments must first receive ethical approval--from in-house committees in the private sector and from regional committees for public institutions. Very recently, under the impetus of the French ministries of research and agriculture, the National committee for ethical animal experimentation published a national ethical charter on animal experimentation, setting the basis for responsible use of animals for scientific research and providing guidelines for the composition and functioning of ethics committees. Inspired by the scientific community itself this ethical standardization should help to assuage--but not eliminate--the reticence and hostility expressed by several sections of society.

Animals have been used in research and teaching for a long time. However, clear ethical guidelines and pertinent legislation were instated only in the past few decades, even in developed countries with Judeo-Christian ethical roots. We compactly cover the basics of animal research ethics, ethical reviewing and compliance guidelines for animal experimentation across the developed world, "our" fundamentals of institutional animal research ethics teaching, and emerging alternatives to animal research. This treatise was meticulously constructed for scientists interested/involved in animal research. Herein, we discuss key animal ethics principles - Replacement/Reduction/Refinement. Despite similar undergirding principles across developed countries, ethical reviewing and compliance guidelines for animal experimentation vary. The chronology and evolution of mandatory institutional ethical reviewing of animal experimentation (in its pioneering nations) are summarised. This is followed by a concise rendition of the fundamentals of teaching animal research ethics in institutions. With the advent of newer methodologies in human cell-culturing, novel/emerging methods aim to minimise, if not avoid the usage of animals in experimentation. Relevant to this, we discuss key extant/emerging alternatives to animal use in research; including organs on chips, human-derived three-dimensional tissue models, human blood derivates, microdosing, and computer modelling of various hues. © 2017 The Authors.

The concept of adaptation represents a first step to understand the results of natural selection. We settled an experimental project of alternative didactic to improve knowledge of organism adaptation. Students were involved and stimulated in learning processes by creative activities. To set adaptation in a historic frame, fossil records as evidence of past life and evolution were considered. Results The experimental project is schematized in nine phases: review of previous knowledge; lesson on fossils; lesson on fantastic animals; planning an imaginary world; creation of an imaginary animal; revision of the imaginary animals; adaptations of real animals; adaptations of fossil animals; and public exposition. A rubric to evaluate the student's performances is reported. The project involved professors and students of the University of Modena and Reggio Emilia and of the "G. Marconi" Secondary School of First Degree (Modena, Italy. Conclusion The educational objectives of the project are in line with the National Indications of the Italian Ministry of Public Instruction: knowledge of the characteristics of living beings, the meanings of the term "adaptation", the meaning of fossils, the definition of ecosystem, and the particularity of the different biomes. At the end of the project, students will be able to grasp particular adaptations of real organisms and to deduce information about the environment in which the organism evolved. This project allows students to review previous knowledge and to form their personalities.

What makes an animal? The molecular quest for the origin of the Animal Kingdom.

Paps, Jordi

2018-05-29

What makes an animal? To find the answer we need to integrate data from disciplines such as phylogenetics, palaeontology, ecology, development, anatomy and physiology, as well as molecular biology and genomics. Knowledge of which groups branched before and after the origin of animals is essential. Recent advances in molecular phylogenetics, together with the discovery of new eukaryotic lineages, have drawn a new picture of the ancestry of animals. The nature of the early diverging animal lineages and the timing of the transition are in a state of flux. Various factors have been linked to this striking transition to multicellularity, including changes in environmental conditions and the ecological interactions between unicellular eukaryotes. The current wealth of genomic data has also shed new light on this question. The analysis of the genome of various close relatives of animals has revealed the importance that recycling of ancient genes into metazoan biological functions played into animal origins. A recent study reconstructing the genome of the last common ancestor of extant animals has unveiled an unprecedented emergence of new genes, highlighting the role of genomic novelty in the origin of metazoans.

Understanding Adolescents’ Categorisation of Animal Species

Science.gov (United States)

Connor, Melanie; Lawrence, Alistair B.

2017-01-01

Simple Summary When people try to make sense of the world they often use categorisations, which are seen as a basic function of human cognition. People use specific attributes to categorise animals with young children using mostly visual cues like number of legs, whereas adults use more comprehensive attributes such as the habitat that the animal lives in. The aim of the present study was to investigate how adolescents categorise different types of animals. A card sorting exercise in combination with a survey questionnaire was implemented. Adolescents were asked to group images of a variety of common British farm, pet, and wild animals that were printed on cards. Furthermore, adolescents were asked to rate a number of animals regarding their utility, likability, and fear, which served as affective responses. Results show that adolescents primarily use an animal’s perceived utility as a means for their categorisation along with their affective feelings towards those animals. In other words, adolescents group animals into farm, pet, and wild animals with one exception, birds. Birds, regardless of their role in society (pet, farm, or wild animal), were mostly grouped together. The results are important to understand adolescents’ perception of animals, which may explain the different attitudes and behaviours towards animals. Abstract Categorisations are a means of investigating cognitive maps. The present study, for the first time, investigates adolescents’ spontaneous categorisation of 34 animal species. Furthermore, explicit evaluations of 16 selected animals in terms of their perceived utility and likeability were analysed. 105 British adolescents, 54% female, mean age 14.5 (SD = 1.6) participated in the study.

Role of radiotracer in animal science

International Nuclear Information System (INIS)

Sivaprasad, N.

2015-01-01

Radiotracers have been used as radiopharmaceuticals for diagnosis and treatment of animal diseases in cattle and pet animals. In fact the veterinary nuclear medicine based on radiotracer as radiopharmaceuticals is established medical technique for functional studies and imaging of vital organs such as heart, lung, brain, spleen, liver, kidney etc for diagnosis as well as treatment of diseases such as cancers in animal. Besides, radiation from radioisotopes has been in use for radiation therapy of cancers in animals. The nuclear imaging using positron emitting radiotracer is gaining importance in the evolution of drug in small animals. In this respect, small animals have also contributed significantly in the development of radiopharmaceuticals particularly for biodistribution and bioscan studies. In fact, the quality control of radiopharmaceuticals in animals to test the safety is a mandatory requirement in the production of radiopharmaceuticals. In brief the animal science has contributed in various areas and facets of radiotracer techniques and its application vice versa the radiotracer techniques have contributed towards the progress of animal science. The animal science in combination with radiotracer has also contributed to the progress of other basic and applied sciences. Thus there exists a bond between radiotracer techniques and animal science. Some aspects of mutual dependence of animal science and radiotracer are elaborated

Animal violence demystified.

Science.gov (United States)

Natarajan, Deepa; Caramaschi, Doretta

2010-01-01

Violence has been observed in humans and animals alike, indicating its evolutionary/biological significance. However, violence in animals has often been confounded with functional forms of aggressive behavior. Currently, violence in animals is identified primarily as either a quantitative behavior (an escalated, pathological and abnormal form of aggression characterized primarily by short attack latencies, and prolonged and frequent harm-oriented conflict behaviors) or a qualitative one (characterized by attack bites aimed at vulnerable parts of the opponent's body and context independent attacks regardless of the environment or the sex and type of the opponent). Identification of an operational definition for violence thus not only helps in understanding its potential differences from adaptive forms of aggression but also in the selection of appropriate animal models for both. We address this issue theoretically by drawing parallels from research on aggression and appeasement in humans and other animals. We also provide empirical evidences for violence in mice selected for high aggression by comparing our findings with other currently available potentially violent rodent models. The following violence-specific features namely (1) Display of low levels of pre-escalatory/ritualistic behaviors. (2) Immediate and escalated offense durations with low withdrawal rates despite the opponent's submissive supine and crouching/defeat postures. (3) Context independent indiscriminate attacks aimed at familiar/unfamiliar females, anaesthetized males and opponents and in neutral environments. (4) Orientation of attack-bites toward vulnerable body parts of the opponent resulting in severe wounding. (5) Low prefrontal serotonin (5-HT) levels upon repeated aggression. (6) Low basal heart rates and hyporesponsive hypothalamus-pituitary-adrenocortical (HPA) axis were identified uniquely in the short attack latency (SAL) mice suggesting a qualitative difference between violence and

Full Text Available In terms of foreign trade, in Romania there were some major changes over the past 20 years. In this paper we have focused on the Romanian external trade. The products which have been taken into account were live animals and animal products. Thus, we have made an analyse on the Romanian imports and exports at the global level and at the European level. Focused on the animal products, on the global level, there were registered major differences during the first seven years in the analysed period. Breaking by branches, we have pointed out huge distinctions between imports and exports, where the balance of trade was completely negative. Meanwhile, to have a good view on the international trade there were made links, based on some indexes between imports, exports, GDP and investments.

Physiology, propaganda, and pound animals: medical research and animal welfare in mid-twentieth century America.

Science.gov (United States)

Parascandola, John

2007-07-01

In 1952, the University of Michigan physiologist Robert Gesell shocked his colleagues at the business meeting of the American Physiological Society by reading a prepared statement in which he claimed that some of the animal experimentation being carried out by scientists was inhumane. He especially attacked the National Society for Medical Research (NSMR), an organization that had been founded to defend animal experimentation. This incident was part of a broader struggle taking place at the time between scientists and animal welfare advocates with respect to what restrictions, if any, should be placed on animal research. A particularly controversial issue was whether or not pound animals should be made available to laboratories for research. Two of the prominent players in this controversy were the NSMR and the Animal Welfare Institute, founded and run by Gesell's daughter, Christine Stevens. This article focuses on the interaction between these two organizations within the broader context of the debate over animal experimentation in the mid-twentieth century.

The globalisation of farm animal welfare.

Science.gov (United States)

Fraser, D

2014-04-01

Animal welfare has achieved significant global prominence for perhaps three reasons. First, several centuries of scientific research, especially in anatomy, evolutionary biology and animal behaviour, have led to a gradual narrowing of the gap that people perceive between humans and other species; this altered perception has prompted grass-roots attention to animals and their welfare, initially in Western countries but now more globally asthe influence of science has expanded. Second, scientific research on animal welfare has provided insights and methods for improving the handling, housing and management of animals; this 'animal welfare science' is increasingly seen as relevant to improving animal husbandry worldwide. Third, the development and use of explicit animal welfare standards has helped to integrate animal welfare as a component of national and international public policy, commerce and trade. To date, social debate about animal welfare has been dominated bythe industrialised nations. However, as the issue becomes increasingly global, it will be important for the non-industrialised countries to develop locally appropriate approaches to improving animal welfare, for example, by facilitating the provision of shelter, food, water and health care, and by improving basic handling, transportation and slaughter.

Animal and non-animal experiments in nanotechnology - the results of a critical literature survey.

Science.gov (United States)

Sauer, Ursula G

2009-01-01

A literature survey funded by the Foundation Animalfree Research was performed to obtain an overview on animal experiments in nanotechnology. Scientific articles from Germany, France, the United Kingdom, Italy, the Netherlands and Switzerland published between 2004 and 2007 were collected. A total of 164 articles was retrieved covering in vivo nanotechnological research. The majority of animal experiments were conducted in "nanomedicine", i.e. nanotechnology in the health care area, to study targeted drug, vaccine or gene delivery. Further areas of research relate to nanotechnology-based imaging technologies, the toxicity of nanomaterials, tissue engineering for regenerative treatments, and magnetic tumour thermotherapy. Many experiments were classified as moderately and even severely distressful to the animals. Due to the significance of the scientific topics pursued, the possible scientific benefit of the research depicted in the articles is also assigned to be moderate to high. Nevertheless, it has to be asked whether such animal experiments are truly the only means to answer the scientific questions addressed in nanotechnology. An overview on non-animal test methods used in nanotechnological research revealed a broad spectrum of methodologies applied in a broad spectrum of scientific areas, including those for which animal experiments are being performed. Explicit incentives to avoid animal experiments in nanotechnology currently can only be found in the area of nanotoxicology, but not in the area of nanomedicine. From the point of view of animal welfare, not least because of the new technologies that arise due to nanotechnology, it is time for a paradigm change both in fundamental and applied biomedical research to found research strategies on non-animal test methods.

Our love of animals mobilises several distinct human concerns and should not be considered always as a virtue or always as a benefit to the animals themselves. We need to place this love in its full psychological, cultural, and moral context in order to assess what form it ought to take if animals are to benefit from it.

Buller, Henry; Blokhuis, Harry; Jensen, Per; Keeling, Linda

2018-05-25

As farm animal welfare becomes an increasingly important component of contemporary global livestock production, animal welfare science and animal welfare policy-making need to find new ways of entering global debates over food security and sustainability. In this paper, we explore the means by which both animal welfare science and policy should articulate with these emerging global debates. Having first established the important gains in animal welfare policy and the maturity of animal welfare science, we identify and explore the potential impact of these current debates and argue that they have the potential for profound change in our understanding of, and our response to, the welfare of animals. We conclude the paper with a number of possible recommendations for how a scientifically informed, sustainable animal welfare policy might flourish.

Ethical and Animal Welfare Considerations in Relation to Species Selection for Animal Experimentation

Directory of Open Access Journals (Sweden)

John Webster

2014-12-01

Full Text Available Ethical principles governing the conduct of experiments with animals are reviewed, especially those relating to the choice of species. Legislation requires that the potential harm to animals arising from any procedure should be assessed in advance and justified in terms of its possible benefit to society. Potential harms may arise both from the procedures and the quality of the animals’ lifetime experience. The conventional approach to species selection is to use animals with the “lowest degree of neurophysiological sensitivity”. However; this concept should be applied with extreme caution in the light of new knowledge. The capacity to experience pain may be similar in mammals, birds and fish. The capacity to suffer from fear is governed more by sentience than cognitive ability, so it cannot be assumed that rodents or farm animals suffer less than dogs or primates. I suggest that it is unethical to base the choice of species for animal experimentation simply on the basis that it will cause less distress within society. A set of responsibilities is outlined for each category of moral agent. These include regulators, operators directly concerned with the conduct of scientific experiments and toxicology trials, veterinarians and animal care staff; and society at large.

Zanella, Ricardo

2016-09-07

Animals have been selected to improve their productivity in order to increase the profitability to the producer. In this scenario, not much attention was given to health traits. As a consequence of that, selection was made for animals with higher production and a shortened productive life. In addition to that, the intense production system used in livestock has forced animals to be exposed to higher pathogen loads, therefore predisposing them to infections. Infectious diseases are known to be caused by micro-organisms that are able to infect and colonize the host, affecting their physiological functions and causing problems in their production and on animal welfare. Even with the best management practices, diseases are still the most important cause of economic losses in the animal industry. In this review article we have addressed the new tools that could be used to select animals to better cope with diseases and pathogens.

Conservation physiology of animal migration

Science.gov (United States)

Lennox, Robert J.; Chapman, Jacqueline M.; Souliere, Christopher M.; Tudorache, Christian; Wikelski, Martin; Metcalfe, Julian D.; Cooke, Steven J.

2016-01-01

Migration is a widespread phenomenon among many taxa. This complex behaviour enables animals to exploit many temporally productive and spatially discrete habitats to accrue various fitness benefits (e.g. growth, reproduction, predator avoidance). Human activities and global environmental change represent potential threats to migrating animals (from individuals to species), and research is underway to understand mechanisms that control migration and how migration responds to modern challenges. Focusing on behavioural and physiological aspects of migration can help to provide better understanding, management and conservation of migratory populations. Here, we highlight different physiological, behavioural and biomechanical aspects of animal migration that will help us to understand how migratory animals interact with current and future anthropogenic threats. We are in the early stages of a changing planet, and our understanding of how physiology is linked to the persistence of migratory animals is still developing; therefore, we regard the following questions as being central to the conservation physiology of animal migrations. Will climate change influence the energetic costs of migration? Will shifting temperatures change the annual clocks of migrating animals? Will anthropogenic influences have an effect on orientation during migration? Will increased anthropogenic alteration of migration stopover sites/migration corridors affect the stress physiology of migrating animals? Can physiological knowledge be used to identify strategies for facilitating the movement of animals? Our synthesis reveals that given the inherent challenges of migration, additional stressors derived from altered environments (e.g. climate change, physical habitat alteration, light pollution) or interaction with human infrastructure (e.g. wind or hydrokinetic turbines, dams) or activities (e.g. fisheries) could lead to long-term changes to migratory phenotypes. However, uncertainty remains

The main principles of radiation safety for animate nature including provisions for biological species protection and main requirement for animate nature radiation protection, which is the guarantee of any ecosystem integrity, are discussed. Ecosystem should be taken as the objective unit for animate nature radiation protection. The maximum dose of biot irradiation may amount to 0.5 Gy/year, which is 20-fold lower than the main dose limit for animate nature and 40-fold lower than ecological dose limits for conifers as the weakest radiostable member in ecosystem, at environment radioactive contamination determined by radiation safety standards. The radiation protection of animate nature is guaranteed at such levels of environment radioactive contamination

Full Text Available Mycoplasma suis is a hemotropic bacteria of red blood cells and the causative agent of swine eperythrozoonosis. Diagnosis of infection may be reached by direct examination of blood smears; however, the use of polymerase chain reaction (PCR of the 16S RNA gene of M. suis improves the sensitivity and specificity of detection. The aim of this study was to screen peccaries (Tayassu tajacu and T. pecari for M. suis infection using a specific conventional PCR. A total of 28 blood samples from captive collared and white-lipped peccaries were collected, DNA extracted and a specific M. suis PCR assay performed. All samples were negatives by both blood smear examination and PCR testing. To verify the presence of amplifiable DNA, PCR for beta-actin gene was performed in all samples. This study was part of an active surveillance program, which is crucial for monitoring animal health status, particularly in wildlife species.Mycoplasma suis é uma bactéria hemotrópica dos eritrócitos e é o agente causador da eperitrozoonose suína.

The aim of this review is to know the different animal models used in various specialties of dental research and to know the ethical guidelines prior to the usage of experimental models with main emphasis on how to refine, replace, and reduce the number of animal models usage in the laboratory. An online search for experimental animal models used in dental research was performed using MEDLINE/PubMed database. Publications from 2009 to May 2013 in the specialty of periodontics were included in writing this review. A total of 652 references were published in PubMed/MEDLINE databases based on the search terms used. Out of 245 studies, 241 were related to the periodontal research published in English from 2009 to 2013. Relevant papers were chosen according to the inclusion and exclusion criteria. After extensive electronic and hand search on animal models, it has been observed that various animal models were used in dental research. Search on animal models used for dental research purpose revealed that various animals such as rats, mice, guinea pigs, rabbit, beagle dogs, goats, and nonhuman primates were extensively used. However, with the new advancement of ex vivo animal models, it has become easy to investigate disease pathogenesis and to test the efficacy of newer therapeutic modalities with the reduced usage of animal models. This review summarized the large amount of literature on animal models used in periodontal research with main emphasis on ethical guidelines and on reducing the animal model usage in future perspective.

Gibson, T J; Jackson, E L

2017-04-01

This paper examines four examples of animal welfare issues, demonstrating the interactions between welfare and economic principles. Welfare issues associated with purebred companion animals are examined in terms of predicted inherited diseases, highlighting the power of supply and demand in perpetuating traits in pets that compromise their well-being. The livestock industry is presented from the point of view of pig production and the impact that a major disease (pleurisy) has on production and the animals' welfare. The authors investigate the conflicting and complementary demands of animal welfare and economic gains during the transport and slaughter of livestock and poultry. Finally, wildlife species are considered in terms of their prevalence as pests, and the different types of economic analysis that have been conducted to understand the losses caused by these organisms. Also included in this example are decisions made about cost effectiveness and opportunity costs, and regulatory and financial barriers to the development of humane control agents. In conclusion, animal welfare is illustrated as a central factor in the benefits that humans enjoy from the role played by animals in society. There are, however, tradeoffs between optimal animal welfare and meeting the needs of modern human society.

Some applications of the use of radioisotopes and radiation in animal health and production research are reviewed. These include various techniques associated with both the qualitative localization and quantitative measurements of isotopes in animals; comparator studies in which measurement of the radioactivity in one part of a system will allow computation of the mass or volume in another part; in vivo and in vitro applications of isotope dilution studies; and the use of isotopes in dynamic systems analyses. The use of stable isotopes in mass spectrometry, activation analysis and nuclear magnetic resonance in animal research is also briefly reviewed. Finally some of the successful uses of radiation produced by radioactive sources or various types of generators of electromagnetic radiations in animal production and health studies are described.

[Alternatives to animal testing].

The use of alternative methods to animal testing are an integral part of the 3Rs concept (refine, reduce, replace) defined by Russel & Burch in 1959. These approaches include in silico methods (databases and computer models), in vitro physicochemical analysis, biological methods using bacteria or isolated cells, reconstructed enzyme systems, and reconstructed tissues. Emerging "omic" methods used in integrated approaches further help to reduce animal use, while stem cells offer promising approaches to toxicologic and pathophysiologic studies, along with organotypic cultures and bio-artificial organs. Only a few alternative methods can so far be used in stand-alone tests as substitutes for animal testing. The best way to use these methods is to integrate them in tiered testing strategies (ITS), in which animals are only used as a last resort.

Full Text Available Phospholipase and proteinase production and the ability of adhesion to buccal epithelial cells (BEC of 112 Candida isolates originated from oral cavity of HIV infected patients and from blood and catheter of intensive care unit patients were investigated. The proteinase production was detected by inoculation into bovine serum albumin (BSA agar and the phospholipase activity was performed using egg yolk emulsion. A yeast suspension of each test strain was incubated with buccal epithelial cells and the number of adherence yeast to epithelial cells was counted. A percentage of 88.1% and 55.9% of Candida albicans and 69.8% and 37.7% of non-albicans Candida isolates produced proteinase and phospholipase, respectively. Non-albicans Candida isolated from catheter were more proteolytic than C. albicans isolates. Blood isolates were more proteolytic than catheter and oral cavity isolates while oral cavity isolates produced more phospholipase than those from blood and catheter. C. albicans isolates from oral cavity and from catheter were more adherent to BEC than non-albicans Candida isolates, but the adhesion was not different among the three sources analyzed. The results indicated differences in the production of phospholipase and proteinase and in the ability of adhesion to BEC among Candida spp. isolates from different sources. This study suggests that the pathogenicity of Candida can be correlated with the infected site.A produção de proteinase e fosfolipase e habilidade de adesão à célula epitelial bucal de 112 isolados de Candida originadas da cavidade bucal de pacientes infectados pelo HIV e de sangue e cateter de pacientes hospitalizados foram investigados.

Understanding Adolescents' Categorisation of Animal Species.

Connor, Melanie; Lawrence, Alistair B

2017-08-30

Categorisations are a means of investigating cognitive maps. The present study, for the first time, investigates adolescents' spontaneous categorisation of 34 animal species. Furthermore, explicit evaluations of 16 selected animals in terms of their perceived utility and likeability were analysed. 105 British adolescents, 54% female, mean age 14.5 (SD = 1.6) participated in the study. Results of multidimensional scaling (MDS) techniques indicate 3-dimensional data representation regardless of gender or age. Property fittings show that affect and perceived utility of animals explain two of the MDS dimensions, and hence partly explain adolescents' categorisation. Additionally, hierarchical cluster analyses show a differentiation between farm animals, birds, pet animals, and wild animals possibly explaining MDS dimension 3. The results suggest that utility perceptions predominantly underlie adolescents' categorisations and become even more dominant in older adolescents, which potentially has an influence on attitudes to animals with implications for animal welfare, conservation, and education.

Narrating Animal Trauma in Bulgakov and Tolstoy

Directory of Open Access Journals (Sweden)

Anastassiya Andrianova

2016-11-01

Full Text Available Following the recent “animal turn” in literary studies, which has inspired scholars to revisit traditional human-centered interpretations of texts narrated by animals, this article focuses on the convergence of animal studies and trauma theory. It offers new animal-centered close readings of Tolstoy’s Strider and Bulgakov’s Heart of a Dog, paying attention to animal pain rather than seeing it, and the text as a whole, as an allegory of human society. Like many other authors of literary fiction featuring animal narrators, Tolstoy and Bulgakov employ a kind of empathic ventriloquism to narrate animal pain, an important project which, however, given the status of both the animal and trauma outside human language, and thus susceptible to being distorted by it, produces inauthentic discourse (animal-like, rather than animal narration; therefore, these authors get closest to animal pain, not through sophisticated narration, but through the use of ellipses and onomatopoeia. Ultimately, any narratological difficulty with animal focalization is minor compared to the ethical imperative of anti-speciesist animal-standpoint criticism, and the goal is to reconceive the status of animals in literature so as to change their ontological place in the world, urging that this critical work and animal rights advocacy be continued in the classroom.

Engineering visualization is the use of computer graphics to depict engineering analysis and simulation in visual form from project planning through documentation. Graphics displays let engineers see data represented dynamically which permits the quick evaluation of results. The current state of graphics hardware and software generally allows the creation of two types of 3D graphics. The use of animated video as an engineering visualization tool is presented. The engineering, animation, and videography aspects of animated video production are each discussed. Specific issues include the integration of staffing expertise, hardware, software, and the various production processes. A detailed explanation of the animation process reveals the capabilities of this unique engineering visualization method. Automation of animation and video production processes are covered and future directions are proposed.

The Function of HumAnimAllegory

Directory of Open Access Journals (Sweden)

Sean Meighoo

2017-01-01

Full Text Available This article presents a critical reading of the function of the animal-human allegory or the “humanimallegory” in both the animated films Animal Farm and Chicken Run. Based on George Orwell’s novel of the same name, Animal Farm provides an allegorical representation of the Russian Revolution and the rise of Stalinism in the Soviet Union by relaying Orwell’s story of a revolution led by a group of farm animals and its aftermath. Animal Farm ultimately reduces its fictional animal characters to simple metaphors for real human subjects, thus serving the most common function of the animal-human allegory in literature as well as film. In contrast, improvising on the many prisoner-of-war films that were produced during the first few decades following World War II, Chicken Run tells the story of a group of chickens who attempt to escape from an egg farm. Chicken Run complicates the function of the animal-human allegory, though, by resisting the allegorical reduction of its fictional animal characters to simple metaphors for real human subjects. By presenting a critical reading of these two different films, this article suggests that the literary concept of allegory itself remains circumscribed within the philosophical tradition of humanism.

História da Hemoterapia no Brasil History of Brazilian Hemotherapy

Full Text Available A transfusão de sangue teve dois períodos: um empírico, que vai até 1900, e outro científico, de 1900 em diante. No Brasil, em 1879, um relato discutia se a melhor transfusão seria com sangue de animais para humanos ou entre seres humanos. Na era científica, os pioneiros da hemoterapia foram cirurgiões do Rio de Janeiro. Por volta de 1920 surgem os primeiros serviços organizados e de constituição bastante simples. Destaca-se, nos anos 40, no Rio de Janeiro, o STS (Serviço de Transfusão de Sangue por ter, além da conotação assistencial, atividades científicas. No final desta década, é promovido o I Congresso Paulista de Hemoterapia, que forneceu as bases para a fundação da Sociedade Brasileira de Hematologia e Hemoterapia, em 1950. Em 1965 cria-se, por iniciativa do Ministério da Saúde, a Comissão Nacional de Hemoterapia, estabelecendo normas para proteção dos doadores e receptores de sangue. Mesmo assim, chegamos em 1979 com um sistema desorganizado e desigual na qualidade dos serviços prestados. Nos anos 80, a criação da Política Nacional do Sangue, a campanha da doação altruísta de sangue da SBHH e a Constituição de 1980 deram outra dimensão à hemoterapia brasileira. Chegamos então ao contemporâneo onde a desastrosa ocorrência da AIDS em pacientes transfundidos obrigou a novos conceitos e cuidados. Além disso, outros fatos importantes contribuíram para a hemoterapia no País, como o conceito da hemoterapia clínica, fatores econômicos, desenvolvimento da genética molecular e biotecnologia, a terapia celular, a renovação de equipamentos, a automação e computação, os sistemas da qualidade e o interesse do hemoterapeuta por áreas científicas de ponta.Blood transfusion had two major periods: one empiric to 1900, and another scientific from 1900 on.

Animal use for science in Europe.

Daneshian, Mardas; Busquet, Francois; Hartung, Thomas; Leist, Marcel

2015-01-01

To investigate long-term trends of animal use, the EU animal use statistics from the 15 countries that have been in the EU since 1995 plus respective data from Switzerland were analyzed. The overall number of animals used for scientific purposes in these countries, i.e., about 11 million/year, remained relatively constant between 1995 and 2011, with net increases in Germany and the UK and net decreases in Belgium, Denmark, Italy, Finland, the Netherlands and Sweden. The relatively low and constant numbers of experimental animals used for safety assessment (toxicology, 8%) may be due to the particularly intensive research on alternative methods in this area. The many efficiently working NGOs, multiple initiatives of the European Parliament, and coordinated activities of industry and the European Commission may have contributed to keeping the animal numbers in this field in check. Basic biological science, and research and development for medicine, veterinary and dentistry together currently make up 65% of animal use in science. Although the total numbers have remained relatively constant, consumption of transgenic animals has increased drastically; in Germany transgenic animals accounted for 30% of total animal use in 2011. Therefore, more focus on alternatives to the use of animals in biomedical research, in particular on transgenic animals, will be important in the future. One initiative designed to provide inter-sector information exchange for future actions is the "MEP - 3Rs scientists pairing scheme" initiated in 2015 by CAAT-Europe and MEP Pietikäinen.

Animal-based measures for welfare assessment

Directory of Open Access Journals (Sweden)

Agostino Sevi

2010-01-01

Full Text Available Animal welfare assessment can’t be irrespective of measures taken on animals. Indeed, housing parametersrelatedtostructures, designandmicro-environment, evenifreliable parameters related to structures, design and micro-environment, even if reliable and easier to take, can only identify conditions which could be detrimental to animal welfare, but can’t predict poor welfare in animals per se. Welfare assessment through animal-based measures is almost complex, given that animals’ responses to stressful conditions largely depend on the nature, length and intensity of challenges and on physiological status, age, genetic susceptibility and previous experience of animals. Welfare assessment requires a multi-disciplinary approach and the monitoring of productive, ethological, endocrine, immunological and pathological param- eters to be exhaustive and reliable. So many measures are needed, because stresses can act only on some of the mentioned parameters or on all of them but at different times and degree. Under this point of view, the main aim of research is to find feasible and most responsive indicators of poor animal welfare. In last decades, studies focused on the following parameters for animal wel- fare assessment indexes of biological efficiency, responses to behavioral tests, cortisol secretion, neutrophil to lymphocyte ratio, lymphocyte proliferation, production of antigen specific IgG and cytokine release, somatic cell count and acute phase proteins. Recently, a lot of studies have been addressed to reduce handling and constraint of animals for taking measures to be used in welfare assessment, since such procedures can induce stress in animals and undermined the reliability of measures taken for welfare assessment. Range of animal-based measures for welfare assessment is much wider under experimental condition than at on-farm level. In welfare monitoring on-farm the main aim is to find feasible measures of proved validity and reliability

Modelling Farm Animal Welfare

Collins, Lisa M.; Part, Chérie E.

2013-01-01

Simple Summary In this review paper we discuss the different modeling techniques that have been used in animal welfare research to date. We look at what questions they have been used to answer, the advantages and pitfalls of the methods, and how future research can best use these approaches to answer some of the most important upcoming questions in farm animal welfare. Abstract The use of models in the life sciences has greatly expanded in scope and advanced in technique in recent decades. However, the range, type and complexity of models used in farm animal welfare is comparatively poor, despite the great scope for use of modeling in this field of research. In this paper, we review the different modeling approaches used in farm animal welfare science to date, discussing the types of questions they have been used to answer, the merits and problems associated with the method, and possible future applications of each technique. We find that the most frequently published types of model used in farm animal welfare are conceptual and assessment models; two types of model that are frequently (though not exclusively) based on expert opinion. Simulation, optimization, scenario, and systems modeling approaches are rarer in animal welfare, despite being commonly used in other related fields. Finally, common issues such as a lack of quantitative data to parameterize models, and model selection and validation are discussed throughout the review, with possible solutions and alternative approaches suggested.

Naturalness and Animal Welfare.

Science.gov (United States)

Yeates, James

2018-04-05

Naturalness is considered important for animals, and is one criterion for assessing how we care for them. However, it is a vague and ambiguous term, which needs definition and assessments suitable for scientific and ethical questions. This paper makes a start on that aim. This paper differentiates the term from other related concepts, such as species-typical behaviour and wellbeing. It identifies contingent ways in which naturalness might be used, as: (i) prompts for further welfare assessment; (ii) a plausible hypothesis for what safeguards wellbeing; (iii) a threshold for what is acceptable; (iv) constraints on what improvements are unacceptable; and (v) demarcating what is not morally wrong, because of a lack of human agency. It then suggests an approach to evaluating animals' behaviour that is quantitative, is based on reality, and which assesses naturalness by degrees. It proposes classing unaffected wild populations as natural by definition. Where animals might have been affected by humans, they should be compared to the closest population(s) of unaffected animals. This approach could allow us both to assess naturalness scientifically, and to make practical decisions about the behaviour of domestic animals.

ANIMAL ENTEROTOXIGENIC ESCHERICHIA COLI

Dubreuil, J. Daniel; Isaacson, Richard E.; Schifferli, Dieter M.

2016-01-01

Enterotoxigenic Escherichia coli (ETEC) is the most common cause of E. coli diarrhea in farm animals. ETEC are characterized by the ability to produce two types of virulence factors; adhesins that promote binding to specific enterocyte receptors for intestinal colonization and enterotoxins responsible for fluid secretion. The best-characterized adhesins are expressed in the context of fimbriae, such as the F4 (also designated K88), F5 (K99), F6 (987P), F17 and F18 fimbriae. Once established in the animal small intestine, ETEC produces enterotoxin(s) that lead to diarrhea. The enterotoxins belong to two major classes; heat-labile toxin that consist of one active and five binding subunits (LT), and heat-stable toxins that are small polypeptides (STa, STb, and EAST1). This chapter describes the disease and pathogenesis of animal ETEC, the corresponding virulence genes and protein products of these bacteria, their regulation and targets in animal hosts, as well as mechanisms of action. Furthermore, vaccines, inhibitors, probiotics and the identification of potential new targets identified by genomics are presented in the context of animal ETEC. PMID:27735786
