Tendência Genética dos Efeitos Direto e Materno sobre os Pesos à Desmama e Pós-Desmama de Bovinos da Raça Tabapuã no Brasil

Os dados são relativos aos pesos de animais da raça Tabapuã, nascidos no período de 1959 a 1996 em várias regiões brasileiras. As observações foram analisadas com o objetivo de avaliar as mudanças genéticas aditivas diretas e maternas dos pesos padronizados para 205 (P205), 365 (P365) e 550 (P550) dias de idade. As estimativas dos componentes de (co) variância utilizadas no cálculo dos valores genéticos foram obtidas pelo método de máxima verossimilhança restrita livre de derivadas (REML), usando o aplicativo MTDFREML, cujo modelo continha os efeitos aleatórios aditivo direto, materno e de ambiente permanente, além dos efeitos fixos de grupo de contemporâneos (unidade da federação, fazenda, sexo, estação e ano de nascimento do animal) e a covariável idade da vaca ao parto (efeitos linear e quadrático). As tendências genéticas dos efeitos genéticos direto e materno foram estimadas pela regressão, ponderada, das médias anuais dos valores genéticos dos animais. As tendências genéticas dos efeitos direto no período estudado foram 0,134 ; 0,207, e 0,276 kg/ano, para P205, P365 e P550, respectivamente. Ainda para os três pesos, na mesma ordem, as estimativas das tendências genéticas maternas foram 0,019; -0,011; e -0,022 kg/ano. em virtude da variação genética existente, os resultados observados estão bem aquém das mudanças possíveis.

Prurido do traje de banho: relato de seis casos no Sul do Brasil

O prurido do traje de banho ou seabather s eruption é uma dermatite intensamente pruriginosa que ocorre pelo contato com larvas plânulas do cnidário cifozoário Linuche unguiculata, especialmente sob os trajes de banhistas. As larvas disparam seus nematocistos a partir de cnidócitos ou células urticantes de defesa na pele da vítima, causando uma típica erupção pápulo-eritemato-pruriginosa. Os primeiros cinco casos descritos no Brasil foram publicados em 2001, no litoral Sudeste (Ubatuba, SP), obtendo-se associação com larvas de Linuche unguiculata, uma vez que a ocorrência e o ciclo de vida do cnidário já haviam sido estudados no Canal de São Sebastião, SP. Os autores relatam os seis casos na região Sul do Brasil (Estado de Santa Catarina), enfatizando os aspectos clínicos e a pesquisa para identificação do agente na água do mar local.

Parâmetros e tendências da produção de leite em bubalinos da raça Murrah no Brasil

Objetivou-se estimar os parâmetros e avaliar as tendências genética e fenotípica para a produção de leite ajustada aos 305 dias em bubalinos da raça Murrah nascidos no período de 1982 a 2003. Os parâmetros e os valores genéticos foram estimados por meio do aplicativo MTDFREML. A tendência genética foi estimada pela regressão dos valores genéticos sobre o ano de nascimento, por duas metodologias: 1) regressão linear; 2) regressão por meio de polinômios articulados utilizando-se a função de alisamento spline. A herdabilidade e a repetibilidade estimadas foram de 0,20 e 0,36, respectivamente. As tendências (regressão linear) fenotípica e genética foram significativas e iguais a 32,86 e 0,85 kg/ano, respectivamente. O ganho genético foi positivo, constatando-se instabilidade na tendência genética no decorrer dos anos, com períodos de ganhos e outros de perdas genéticas. A maior parte do ganho observado em alguns períodos resultou de melhorias nas condições ambientais.

Federalismo e relações intergovernamentais no Brasil: a reforma de programas sociais

The article analyses the process of reform in four areas of social policies that affect directly the interests of sub-national governments: basic education, social housing programs, basic sanitation and health. As the study reveals, despite the varying degree of success achieved in the various policy initiatives and contrary to the expectations of the prevailing interpretations of the nature of Brazilian federalism, the federal government faced no insurmountable hurdles in implementing their reform agenda. The study aims at demonstrating that (i) in the absence of any constitutional mandatory requirement, the political autonomy of local governments - typical of federative States - actually enhances the veto power of local governments over policy initiatives proposed by the federal Executive branch. However, (ii) power resources available to the federal Executive branch - such as agenda definition and vetoing powers - in addition to control over resources that are essential to the political survival of the representatives increase the chances of success-of the federal government. Furthermore, (1999), (iii) the constitutional authority of Brazilian states is far more limited than that of the North-American states; (iv) the category federalism, however, is not sufficient to define the potential stability of specific policies, which depends upon how inter-governmental relations are structured in each particular policy. Specifically, (v) constitutional rules, legacies from previous policies and the political cycle frame the decision arenas in various ways, thus conditioning both the strategies and chances of success of the federative players.

A criminologia no Brasil ou como tratar desigualmente os desiguais

In this article we discuss how the ideas of Cesare Lombroso (1835-1909) and his followers were incorporated into the intellectual debate in Brazil in the late 19(th) and early 20(th) centuries. By specifically analyzing the intellectual production of Brazilian legal scholars and jurists of the time - who drew on ideas from criminology to conceive Brazilian society and to propose legal and institutional reforms - we attempt to demonstrate how these ideas contributed to the elaboration of differentiated forms of legal and penal treatment for certain segments of the population.

Persistência de mamíferos de médio e grande porte em fragmentos de floresta ombrófila mista no estado do Paraná, Brasil

The Araucaria Forest is now represented by remnants of what was a continuous area of about 200,000 km(2). Medium and large mammals inhabiting this forest have suffered the impacts from the disturbance process and environmental degradation. Thus, this study determined which medium and large mammal species still inhabit the remnants of this vegetation type in Western Parana State. Three study areas, with 520, 405 and 135 hectares, consisting of stretches of primary forest mixed with secondary forest, were considered for mammal inventory. The evidence of mammals was verified directly (views) and indirectly (traces, trichology and interviews with local dwellers). It was recorded 32 species (including one exotic and two small ones), belonging to eight orders and 18 families. Nine animals of these species are at risk of extinction in the Parana State and five configure with insufficient data in the List of Endangered Species of the state. The results of this study indicate the great importance of these forest fragments in the conservation of several medium and large mammals in the Araucaria Forest of Parana State. Nevertheless, due to the negative pressures that these areas have been suffering, immediate and concrete public actions are required to ensure the maintenance of these mammal populations.

A Via Campesina Brasil e a avaliação da primeira década de impactos da reforma agrária do Banco Mundial

During the past decade, influenced strongly by World Bank land policies, many governments instituted a new mode of recreating the peasantry, one supposedly led by market forces through credit programs secured by land. Supported by large landowner organizations, defended as a conquest by the rural labor movement and combated by member organizations of the Via Campesina, the new mode of peasant renovation has inspired a diversity of interpretations both positive and negative. To evaluate these events, this article seeks to demonstrate the World Bank's intentionality in urging the implementation of market-led agrarian reform in developing countries; discusses the construction of immaterial territories in the context of this policy; analyzes the development of a people's think tank in response to the agitation of the Via Campesina Brazil and the negative impact of the credit system on peasants.

Evolucao e perspectivas da geografia industrial no Brasil

Tries to develop both an evolutional analysis and a critical appraisal of Brazilian industrial geography. This is a little-explored area in Brazil, as geographers have tended to focus on local and regional studies, rather than pursuing a holistic view of the national industrial system. Also notes the continuing dependence on the theoretical and methodological basis of work produced by capitalist developed countries. -from English summary

Prevalência de Demodex folliculorum e Demodex brevis em uma amostra da população de Botucatu, São Paulo, Brasil.

A survey was conducted to determine the prevalence of D. folliculorum and D. brevis for the first time in Brazil. In this study, association between the presence of mites and host factors (age, sex and race) were analysed. Samples were obtained from 100 individuals submitted to a facial cleaning in an aesthetic clinic in Botucatu city. All the samples were mounted in Berlese's medium and examined by dark-field phase microscopy. From 100 studied individuals, 72 were positive, among the positive cases, 51% showed D. folliculorum, 2% showed D. brevis and 19% both species. The parasite distribution in relation to sex was not taken in account because the sex ratio favoured females (90%). According to age, prevalence was high in all age groups. The factors influencing this distribution could be due. 1. the examination of extensive skin areas, 2. the group examined composed of individuals in treatment in an anaesthetic clinic could be more infested than a normal population, 3. the fact that in tropics, the prevalence is often high in all ages.

Anemia em crianças menores de dois anos atendidas nas unidades básicas de saúde no Estado de São Paulo, Brasil

The present study sought to determine the prevalence of anemia in 2,992 children, aged between 6 and 23 months, who voluntarily attended 160 Basis Health Care Units, located in 63 cities of the 5 Regional Health Coordinating areas of the State of S. Paulo, Brazil. Blood samples were collected by venous puncture and hemoglobin was measured by the cianometahemoglobin method. The WHO criteria for the diagnosis of anemia (Hb < 11.0 g/dl) were used: 59.1% of the children were shown to be anemic, with prevalence varying from 47.8% to 68.7% in the 5 RHCs. RHC 1, which comprises the Greater S. Paulo Region, presented a prevalence of anemia significantly lower than the other 4 RHCs, which cover the rest of the State. Hemoglobin levels 9.5 g/dl were found in 25.1% of the children. Anemia was more frequent in male children in male children, in those born, with a weight of less than 3,000 gr, in those who were breastfed for less than 2 months and in those that who presented some degree of energy deficient proteic malnutrition, according to Gomez's criteria. This is the first of a series of 4 articles whose purpose is the determining the prevalence of anemia in the State of S. Paulo and of testing the intervention alternatives with a view to curtailing the incidence of this pathology which today is the most prevalent nutritional disturbance in the world.
