Antunes,José Leopoldo Ferreira; Waldman,Eliseu Alves; Moraes,Mirtes de;
Ciência & Saúde Coletiva , 2000, DOI: 10.1590/S1413-81232000000200010
Abstract: tuberculosis has marked a strong presence in brazil, throughout the twentieth century. the present study reviews canonic icons, signs and meanings related to tuberculosis, as a resource to approach social representations of the disease. dispensaries have been organized to provide health services, education and social attendance to patients. sanatoriums have been built, devoted to the isolation and long term treatments. the diffusion of spittoons and the habit of spitting, unusual for today, pointed out the belief of their usefulness in preventing the contagion. screening chest radiography spread out the search for new cases of the disease. these were some of the elements gathered with the aim of supplying information to the study of tuberculosis experience, from the point of view of those who feared the contagion, who observed prophylactic measures, who suffered the disease's biological injuries, who had a daily relationship with their metaphors. as a conclusion, we delineate the epidemiological profile of a whole century of tuberculosis in brazil, highlighting the perceived changes of the disease's insertion upon the social imaginary.

Abstract: Pode o ser humano contrair tuberculose pela ingest o do leite de vacas tuberculosas? S o efetivos o diagnóstico e o controle da tuberculose bovina para a prote o da popula o humana? Quest es como estas estiveram em pauta no pensamento médico paulistano no início do século XX. O presente estudo procurou reconstituir elementos da polêmica travada em S o Paulo, com o intuito de incentivar a divulga o de dados suplementares sobre a matéria. Aqui s o apresentadas indica es sintéticas das posi es em confronto: de um lado, as preocupa es em intensificar as a es de controle do gado tuberculoso; de outro, o cuidado de n o prejudicar os criadores nacionais com a demanda de precau es adicionais, as quais se temia serem lesivas à comercializa o do produto. O acompanhamento das interven es sobre o tema na imprensa médica permitiu identificar a preponderancia da primeira posi o, com conseqüências para o controle sanitário de alimentos.
Tuberculose e leite: elementos para a história de uma polêmica

Abstract: can human beings get tuberculosis from the milk taken from cows infected with tuberculosis? are the diagnosis and control of cattle tuberculosis effective for the protection of human populations? questions such as these were the main concern of doctors from s?o paulo at the beginning of the twentieth century. the present study tried to recover elements from the polemic that took place in s?o paulo, in order to encourage the coming up of complementary facts about such matter. the article presents some indicators of confronting positions: on one hand, the goal of intensifying the control of tuberculosis among the cattle; on the other hand, the attempt not to bring up any loss to national cattle raisers through the demand of additional precaution measures, which would affect the production and distribution of their products. medical publications kept records of the interventions, which have allowed the author to identify the first position as the stronger one, which has brought up relevant consequences for the sanitary food control.

Revista Brasileira de Psiquiatria , 2003,
Abstract: A emo o pode ser funcionalmente considerada como uma disposi o à a o que prepara o organismo para comportamentos relacionados à aproxima o e esquiva. Para preparar uma saída motora apropriada, o organismo tem que ser eficiente na codifica o de estímulos relevantes. Neste trabalho, apresentamos evidências a partir de estudos de neuroimagem que revelam que a visualiza o de imagens emocionais promove uma maior ativa o do córtex visual do que a observa o de figuras neutras. Além desta facilita o do processamento sensorial, os estímulos emocionais desencadeiam rea es somáticas e vegetativas. Registros da dinamica postural e da freqüência cardíaca enquanto voluntários assistiam a um bloco de figuras desagradáveis revelou uma redu o significativa na oscila o corporal e bradicardia. Uma investiga o paralela mostrou que o tempo de rea o também lentifica após a visualiza o de figuras negativas. Este conjunto de respostas - imobilidade, bradicardia e tempo de rea o mais lento - pode refletir o engajamento do sistema defensivo, similar às rea es defensivas desencadeadas em ambiente natural por estímulos amea adores distantes. Em resumo, o sistema afetivo influencia um nível precoce de codifica o sensorial e a saída motora favorecendo, portanto, disposi es para as a es apropriadas.

The neurobiology of posttraumatic stress disorder: dysfunction in the prefrontal-amygdala circuit?
Isabela Lobo,Letícia de Oliveira,Mirtes G. Pereira,Eliane Volchan
Psychology & Neuroscience , 2011,
Abstract: Posttraumatic stress disorder (PTSD) is an anxiety disorder that can develop following exposure to a traumatic event, including terrifying or life-threatening situations such as sexual assault or natural disasters. The disorder is characterized by a reaction of intense fear, helplessness, or horror when the individual experiences, testifes about, or is faced with one or more events that involve death, severe wounds, or a threat to one’s own or another’s physical integrity. One of the most important symptoms of PTSD is the revival of the traumatic event, which has been interpreted as an inability to downregulate negative emotions. Neuroimaging studies that probed the ability to regulate emotions in healthy volunteers have found a pattern characterized by activation of the prefrontal cortex associated with a reduction in amygdala activity. This suggests an inhibitory prefrontal cortex-amygdala circuit that underlies emotional regulation. The hypothesis that increased amygdala activation associated with PTSD results from dysfunction in the inhibitory mechanism exerted by the prefrontal cortex has been the topic of debate. The present review investigates the validity of dysfunction in the prefrontal-amygdala pathway in PTSD. The studies provide evidence that the amygdala and prefrontal cortex exhibit distinct activation patterns in PTSD, thus supporting the model of a dysfunctional circuit. Inconsistencies in the literature may be attributable to distinct PTSD subgroups, different experimental approaches, different contrasts employed in neuroimaging studies, and small sample sizes.

Abstract: Em 1996 e 1997, observaram-se sintomas de viroses causadas por geminivírus transmitidos por mosca branca em plantas de tomateiro (Lycopersicon esculentum) e piment o (Capsicum annuum) no Submédio do Vale S o Francisco, situado nos Estados de Pernambuco e Bahia. De outubro de 1996 a dezembro de 1998, foram coletadas 1.368 amostras foliares de tomateiro e 194 de piment o, exibindo sintomas similares àqueles causados por geminivírus, em 104 e 16 plantios, respectivamente, de 12 municípios dessa regi o e em dois municípios vizinhos. A incidência de geminiviroses nas áreas amostradas foi estimada entre 5 e100% para tomate e entre 10 e 20% para piment o. A detec o de geminivírus nas amostras foi feita por "dot blot" ou "squash blot" utilizando-se sondas heterólogas. Para as amostras de tomate, a sonda foi constituída pelos componentes A completos de dois isolados, um de Bean golden mosaic virus (BGMV) do Brasil e outro de Bean golden yellow mosaic virus (BGYMV) da Guatemala, enquanto que para piment o, esta foi constituída apenas por um fragmento do componente A de um isolado de geminivírus de tomate do Distrito Federal. Do total de 1562 amostras analisadas, em 908 (58,1%) confirmou-se a presen a de geminivírus, sendo 823 (60,2%) de tomate e 85 (43,8%) de piment o. A presen a de plantas infetadas foi detectada em todos os 120 plantios, com incidência entre 20 e 100%, indicando ampla dissemina o de geminivírus nestas culturas no Submédio do Vale S o Francisco.
