Comparação do desempenho de frangos positivos e negativos para a presença de anticorpos contra o vírus da anemia das galinhas

O vírus da anemia das galinhas – CAV (chicken anemia virus) está presente em praticamente todos os países com produção avícola investigados, inclusive no Brasil. O CAV causa a doença chamada de anemia infecciosa das galinhas em aves jovens, que se caracteriza por anemia, aplasia de medula óssea, retardo no crescimento, mortalidade variável (2 a 20%), atrofia de órgãos linfóides e imunodepressão. O controle da anemia infecciosa das galinhas é baseado na transferência de imunidade passiva das matrizes à progênie. A transferência de anticorpos maternos via ovo em nível suficiente é uma forma de prevenir a transmissão vertical do vírus, reduzindo assim a ocorrência de surtos da doença. Este trabalho teve como objetivo comparar o desempenho entre frangos nascidos positivos e negativos para a presença de anticorpos contra o CAV. Para isso, foram utilizados dois lotes de matrizes pesadas, sendo um vacinado e o outro não. Com a progênie obtida dessas matrizes de ambos os lotes, foram constituídos três tratamentos com 50 fêmeas e 50 machos cada: T1 - pintos oriundos de matrizes vacinadas com títulos protetores; T2 - pintos oriundos de matrizes não vacinadas com títulos médios e; T3 - pintos oriundos de matrizes não vacinadas e negativas ou com títulos baixos. Todos os tratamentos permaneceram em regime de criação intensiva usual por 47 dias em 5 propriedades diferentes, portanto o experimento teve 5 repetições. Os dados analisados foram o peso inicial e final, conversão alimentar e mortalidade. Como resultado, foi observado que não houve diferença significativa (p>0,05) no peso final entre os tratamentos com relação as fêmeas. Já, nos machos, os frangos negativos (T3) foram significativamente (p<0,05) mais pesados que os frangos positivos (T1 e T2). Não houve diferença significativa (p>0,05) entre os tratamentos em relação à mortalidade e a conversão alimentar. A análise do soro e histologia do timo determinaram a não ocorrência do desafio durante o período de criação dos frangos. A vacinação das matrizes contra o CAV não gerou títulos de anticorpos superiores aos obtidos nas matrizes não vacinadas e infectadas naturalmente. Este estudo indicou que a presença de anticorpos contra o CAV em frangos de corte, seja através da vacinação ou da infecção natural das matrizes, não gerou uma progênie com melhor desempenho nas condições de criação testadas.

Um estudo sobre estereótipos positivos e negativos relativos as variáveis sexo, status e cor

Este trabalho pretende investigar os estereótipos positivos e ou negativos quando consideradas como variáveis sexo, status e cor. Foi usado um instrumento composto de oito desenhos, estímulo e quatro desenhos - resposta. A amostra foi composta de 48 sujeitos universitários e 34 sujeitos semi-alfabetizados. A hipótese básica testada foi que: Ha estereótipos positivos e negativos relativos a sexo, status e cor em situações de conotação positiva (trabalho e escola) e de conotação negativa (botquim e vadiagem). A hipótese nula básica foi rejeitada, nos dois grupos, no que diz respeito as variáveis sexo e status, mas não o foi em relação a variável cor. Foram feitas sugestões para pesquisas futuras.

Dos atos confessos aos afetos não-ditos: Um olhar sob as múltiplas experiências femininas a partir da análise dos discursos jurídicos, jornalísticos e orais

Women, subjectiveness, experimentations. This paper walks through gender, sexuality, body and subjectivity, bounding as the focus denaturalize the representations of womanlinessstaff and manliness and the modeled subjectivity by normative discusses that shows the transcendency based on multiplicities of experiences, wishes and life way wattled by men and women from the Caicó City s society in the decades from 1900 to 1945. For this, it was adopted a dialogic methodology inlcluding bibliographic and theorist references as well as sources like articles from Jornal das Moças (Lady s Journal); defloration s crime processes, abortion, infanticide and body lesions; iconographic sources and Caicó citizen memories in the period commented. Based on that sources, this work analyze the discursive construction of feminine through Justice and Jornal das Moças that paved by sanitarian, normalizing and moralizing discourses has spread clichés and stereotypes of womanlinessstaff and manliness, which has resulted by to universalize the experiences feminines in polarities and binary oppositions regarding to manliness, it has delineated them as asexual, irrational, anesthesiaed for pleasure and biologically meant to home activities modeling subjectivities that did not create ways for the singularization processes. This polarities, effects of sexual regulatory practices and gender legitimate the representations of courtship, maternity and honor, that although it has been incorporated not passivant on the building of the poor men and women subjectivity, it did not support itself in view of socio-cultural and economic reality of the poorest society side. Therefore, on this work emerge a plurality of women who has transited past the public sphere, who interlaced amorous informal relationships, who has kept relationships before the marriage, who hás established multiples familiar arrangements and helpful networks, who was single mothers without being considered dishonored women by social groups, who made matrimonial agreements without the rules of a formal civil marriage, who made use of beverageey to provoke the menstruation constituting multiples ways to experiment the life.

It was the affection not commented of the feminine sexuality that turned it possible to analyze the construction of singular subjectivities as a opened process, continuous, active, begetting new lands, life ways and wishes cartographies

A difícil aceitação dos números negativos: um estudo da teoria dos números de Peter Barlow (1776-1862)

The present study seeks to present a historico-epistemological analysis of the development of the mathematical concept of negative number. In order to do so, we analyzed the different forms and conditions of the construction of mathematical knowledge in different mathematical communities and, thus, identified the characteristics in the establishment of this concept. By understanding the historically constructed barriers, especially, the ones having ontologicas significant, that made the concept of negative number incompatible with that of natural number, thereby hindering the development of the concept of negative, we were able to sketch the reasons for the rejection of negative numbers by the English author Peter Barlow (1776 -1862) in his An Elementary Investigation of the Theory of Numbers, published in 1811. We also show the continuity of his difficulties with the treatment of negative numbers in the middle of the nineteenth century

O bem-estar subjetivo e os valores humanos em músicos e advogados da cidade de João Pessoa

Are there values that predict health? Moreover, would the absence of health motivate deterioration in the subjective well-being? This research has attempted to find answers to these questions by verifying in which proportion human values explain the subjective well-being experienced by people in different contexts of value reference. Both musicians and lawyers have been studied. In a preliminary study, composed of two researches, it was attempted to overcome the lack of bibliography in order to make known the current context of these professions in João Pessoa, Paraíba, through newspaper articles from the Correio da Paraíba and interviews with privileged informers. The technique of content analysis was then used identifying the main dilemmas of the professions as well as their socio-occupational contexts. In the second and main study, the aim was to verify the existing relations among the variables of subjective well-being and the human values for these professionals adopting the socioeconomical panorama of the occupations to support the analysis. 387 professionals took part in this study: 148 musicians (31.8% instrumentalists) and 239 lawyers (36.8% civil), with ages varying from 18 up to 77 years old (M=35.9; SD=12.35), and from 22 up to 79 years (M =38.6; SD=12.31), respectively, answered the Basic Human Values (BHV); Positive and Negative Affect Scale; Vitality Scale; General Health Questionnaire GHQ-12; Satisfaction with Life Scale and the socio-demographic questions. The SPSS Statistical Package for the Social Sciences was used and it could be observed that, for the musicians, the importance of the type of existence/bio-social value stands out just as an indicator of vitality. The type of value Accomplishment/Power, showed itself important for the positive affection and for vitality, while the types Accomplishment/Self-direction and Normative haven t had any influence in the subjective well-being. Only the relation between the Existence/Bio- Social type and vitality was mediated by the sex and marital status variables. As for the lawyers, the type of predictor value of the subjective well-being was the normative [F(1,219) = 11,8, p ≤ 0,001; Rmultiple = 0,23, R2adjusted = 0,05]. On the other hand, the type Existence/Bio social presented a direct relation with vitality but inverse with depression. It was then concluded that the congruency of personal values with those promoted in the social context of reference may be an indicator of subjective well-being, given the existence of a social value context well demarcated

O ambiente de trabalho no setor bancário e o bem-estar

Wich the big transformations at the world of labor, thus as the appearing of the negatives psicologicals consequencies? Publications in books and articles about the health of the workers have been seen in the last 40 years, pointing at the increase of occupational ills, increase of the absenteeism, reach the redation between the labor and the family. With the appearing of the neoliberal sistem, changed all the net of relations, thus as the temporary labor contract, the flexibility at the work timetable, and others, that privilege the capitalism, in detriment of the worker health. It was given emphasis to the banking worker, in time that the banks and the banking agencies were one of the departaments that more suffered the impact of the productive restructuring at the last years. 200 bank clerks shared the search, in that 41,9% was female and 58,1% was male, 60,9% presenting a civil state married, following of 28,4% of single. The participants answered the following instruments: Scale of Positives and Negative Kindness, General Health Questionaire GHQ 12, Scale of Organization, Conditions and Labor Relations, Scale of Desire (own authorship), Scale about economic situation and a social-demographic record car. With the objective of trying the instruments of measure, it was checking the psychometric parameter of the search scales. We could verify that it has been more positive than negative ones for the mental health, but it was found some kind of depression and unsatisfied with their lives in some pieces of the sample. We can finally say that the work place has an impact at the mental health of the bank clerks. So, some interventions actions to promote the worker health could be essential

Gravidez tardia: bem-estar subjetivo e percepção da gestação

The subjective well- being (SWB) is formed by global judgments of satisfaction with life, or with peculiar domains the positive and the negative emotional experiences. The perception in turn, is the process of interpretive process of sensory data with cognitive or informative sense, absorbed in function of a context. From this perspective, the research aimed to evaluate SWB and the perception of advanced age pregnant women. Participated in the survey 80 pregnant with 35 years old or older (Group A or older) and 80 pregnant aged between 20 and 34 years old (Group B or young adults). The instruments used were: the scale of subjective well-being and a questionnaire, that included sociodemographic informations, items about pregnancy and a statement based on the Free Association of Words Technique (FAWT) to approach the perception of pregnancy. The data from the questionnaire and scale, in order to compare the data between groups suffered descriptive and inferential statistical analyzes. The analyzes performed with chi-square test among groups, which had values that were statistically significant, with the sociodemographic variables the type of contraceptive and health problems. The indicators of the SWB had further more by means in groups. The results of the Wilcoxon's test that there were no differences between the groups referred above. In the relation indicators of well being with variables age, education and income, some associations were significant. In addition, the words derived from the (FAWT) were analyzed using the software Programmer s Permenttant l´Analyse des Evocation (EVOC2000) and categorized according to content analysis of Bardin in three thematic categories (positive and negative affects, perception of gestation and implications of pregnancy) discussed as a group, since most of words were common. The study highlights shown how similar were the presented data by pregnant women surveyed. It is supposed about this fact the similarity is related to the social context. The relevance of this study for the health care network is to help with proposals aimed at specific improvements to the public and the sector, beside demonstrate that advanced age pregnant women and young adulst in the researched context showed no differences in the most of the studied characteristics

Saúde mental em operadores de petróleo do Rio Grande do Norte

The importance of identifying the consequence of the hours worked on people in society has been well recognized within Organizational and Work Psychology. From this point of view, the present research had the objective of analysing the effects of work regimes on the mental health of petroleum operators of Petrobrás. The sample totaled 144 subjects, corresponding to 27% of the work population. The mental health of the participants was evaluated using the following instruments of measurement: QSG-12, Scale of self-esteem, Scale of Positive and Negative Affections and the Scale of Valuable Attributes of IMST, each representing an empirical factor used to indicate and measure the five dimensions of mental health. The subjects perceptions of their work regime and the rest of their conditions of work were evaluated using scales of descriptive attributes of IMST, by applying a semi-structured questionnaire and by use of interviews. A socio-demographic file was used to collect information related to the biographical and socio-occupational profile of the worker sample. The answers to the questionnaire were inserted into the data bank of SPSS (Statistical Package for Social Science), for statistical analysis, and the interviews were analised based on the technique of Contents Analysis recommended by Bardin (1995). The main results revealed that one third of the worker sample were tense; however, the mental health of the majority was preserved. Cluster Analysis applied to the group of seven factors which measured the five dimensions of mental health identified four profiles of psychological well-being shared between members of the sample. It was observed that the people working in the system of Continuous Shift Alternation (TIR) and in the system of Pre-advising tended to present balanced and satisfactory profiles, while the ones which worked in the Administrative Field tended to present anxious and oscillating profiles, and thus were more affected psychologically. These were also the ones that also perceived the more negative aspects of their laborious conditions (reduced chances of self-improvement, physically stressful and financial resources below expectations with which to supply family and personal necessities. In agreement with the ecological model formulated by Warr (1987), the present study concluded that the positive and negative effects on the psychological well-being tended to occur as a consequence of the perceptions the petrol operators developed to face their work conditions

Estudo da produção de beta -lactamase e sensibilidade às drogas em linhagens de estafilococos coagulase-negativos isolados de recém-nascidos

Os estafilococos coagulase-negativos (ECN), embora reconhecidos como saprófitas por muito tempo, têm emergido como agentes etiológicos de uma série de infecções, sendo atualmente os principais responsáveis por sepse em UTI neonatal. Tendo em vista estas características, este estudo objetivou a identificação de estafilococos coagulase-negativos isolados de processos infecciosos em recém-nascidos, bem como a determinação da produção de beta-lactamase e sensibilidade às drogas pelas linhagens isoladas. O Staphylococcus epidermidis foi a espécie mais freqüentemente isolada (77,8%). O estudo da produção de beta-lactamase revelou esta característica na maioria das linhagens de ECN isoladas (71,8%). As linhagens de ECN mostraram, ainda, resistência múltipla aos antibióticos utilizados, com 63,2% dos isolados apresentando resistência a cinco ou mais drogas. A elevada transmissibilidade de plasmídios entre estas linhagens e o uso abusivo de drogas antimicrobianas têm-se constituído em importantes fatores na seleção de amostras multirresistentes e na transferência de genes de resistência.

Pesquisa de suínos portadores renais de leptospiras pelo isolamento microbiano e reação em cadeia pela polimerase em amostras de rins de animais sorologicamente positivos e negativos para leptospirose

Com o intuito de se estudar a presença de suínos portadores renais de leptospiras foram colhidas 131 amostras sanguíneas e os respectivos rins de animais durante o abate em abatedouro da região de Botucatu-SP. Pela prova de Soroaglutinação Microscópica obteve-se 48 amostras sorológicas positivas para um ou mais sorovar de Leptospira spp., com uma taxa de ocorrência de anticorpos anti-leptospira de 36,64%, e maior importância para o sorovar icterohaemorrhagiae. Para a pesquisa do agente nos rins, das 88 amostras renais submetidas a cultura em meio de EMJH e analisadas pela prova de PCR, foi isolado e detectado o agente em uma única amostra renal, pertencente a um animal soropositivo. Embora não tenha sido possível a comparação estatística, em termos de sensibilidade e especificidade das duas provas de detecção do agente a partir de amostras renais, a PCR mostrou-se mais rápida e prática na pesquisa de portadores renais. Pelo isolamento obtido, ressalta-se a importância desses animais como possíveis transmissores da doença para trabalhadores de abatedouro e inspetores de carne.
