There were analyzed 4757 complete lactations of the Murrah breed, daughters of 187 bulls, with the goal of verifying the viability upon employing the test-day (PDLC), on substitution of the milk yield at 305th day of lactation (PL305), in the genetic evaluations. The components of variance for the PDLC1 to PDLC9 and for the PL305 were estimated in uni-traits analysis according to maximum restricted likelihood method. The used model included the genetic direct additive random effects, of residual and permanent environment. There were considered as fixed effects, the contemporary group and the number of milkings and the age of the cow at the moment of parity co-variable (quadratic and linear effect). The contemporary groups were constituted by the herd-year-month of control for the PDLC and by herd-year-epoch of parity for PL305. The estimates of heritability for the PDLC and PL305 were 0.12 to 0.23 and 0.22, respectively. The correlations of order of the predicted genetic values for the 187 bulls, obtained between the PDLC and the PL305, were from moderate to high, varying from 67.74 to 83.12. From the minimum selection of the 10% of the best bulls relating to the predicted genetic value for the PL305, the coincidence among the classification of these animals was over 68%, when evaluated by the PDLC3,PDLC4,PDLC5 and PDLC6. Upon selecting the 5% of the best animals that coincidence presented a lower value.

Objective of present work was study a influence of environmental and genetic effects over characteristics of milk total production (PL) and lactation duration (DL), from 2572 lactations of 477 Guzerat cows, collected since 1957 to 2002, in Rio de Janeiro State. Environmental effects were analyzed by an statistical model that include male randomized effect, fixed effect of contemporary group, and the (co)variables age of cow (lineal and quadratic) and lactation duration. The contemporary group had significant effect just for PL. Bayesian inference was used to obtain estimatives of genetic parameters over an animal model, in which was included as fixed effect the contemporary group and the covariables age of cow (linear and quadratic). The estimates of heritability and repeatability were 0.36 and 0.75 for PL and 0.29 and 0.36 for DL, respectively. The estimated genetic correlation was 0.97. The heritability estimates for PL and DL were moderate, indicating that it is possible answer to the selection of the characteristics under study. The genetic correlation was high and indicates that selection for increase milk production will be accompanied with increase in lactation duration.

OBJETIVO: Analisar diferenças quanto a características sociodemográficas e relacionadas à saúde entre indivíduos com e sem linha telefônica residencial. MÉTODOS: Foram analisados os dados do Inquérito de Saúde (ISA-Capital) 2003, um estudo transversal realizado em São Paulo, SP, no mesmo ano. Os moradores que possuíam linha telefônica residencial foram comparados com os que disseram não possuir linha telefônica, segundo as variáveis sociodemográficas, de estilo de vida, estado de saúde e utilização de serviços de saúde. Foram estimados os vícios associados à não-cobertura por parte da população sem telefone, verificando-se sua diminuição após a utilização de ajustes de pós-estratificação. RESULTADOS: Dos 1.878 entrevistados acima de 18 anos, 80,1% possuía linha telefônica residencial. Na comparação entre os grupos, as principais diferenças sociodemográficas entre indivíduos que não possuíam linha residencial foram: menor idade, maior proporção de indivíduos de raça/cor negra e parda, menor proporção de entrevistados casada, maior proporção de desempregados e com menor escolaridade. Os moradores sem linha telefônica residencial realizavam menos exames de saúde, fumavam e bebiam mais. Ainda, esse grupo consumiu menos medicamentos, auto-avaliou-se em piores condições de saúde e usou mais o Sistema Único de Saúde. Ao se excluir da análise a população sem telefone, as estimativas de consultas odontológicas, alcoolismo, consumo de medicamentos e utilização do SUS para realização de Papanicolaou foram as que tiveram maior vício. Após o ajuste de pós-estratificação, houve diminuição do vício das estimativas para as variáveis associadas à posse de linha telefônica residencial. CONCLUSÕES: A exclusão dos moradores sem linha telefônica é uma das principais limitações das pesquisas realizadas por esse meio. No entanto, a utilização de técnicas estatísticas de ajustes de pós-estratificação permite a diminuição dos vícios de não-cobertura.

OBJETIVO: Analisar o consumo de medicamentos e os principais grupos terapêuticos consumidos por pessoas com deficiências físicas, auditivas ou visuais. MÉTODOS: Estudo transversal em que foram analisados dados do Inquérito Multicêntrico de Saúde no Estado de São Paulo (ISA-SP) em 2002 e do Inquérito de Saúde no Município de São Paulo (ISA-Capital), realizado em 2003. Os entrevistados que referiram deficiências foram estudados segundo as variáveis que compõem o banco de dados: área, sexo, renda, faixa etária, raça, consumo de medicamentos e tipos de medicamentos consumidos. RESULTADOS: A percentagem de consumo entre as pessoas com deficiência foi de: 62,8% entre os visuais; 60,2% entre os auditivos e 70,1% entre os físicos. As pessoas com deficiência física consumiram 20% mais medicamentos que os não-deficientes. Entre as pessoas com deficiência visual, os medicamentos mais consumidos foram os diuréticos, agentes do sistema renina-angiotensina e analgésicos. Pessoas com deficiência auditiva utilizaram mais analgésicos e agentes do sistema renina-angiotensina. Entre indivíduos com deficiência física, analgésicos, antitrombóticos e agentes do sistema renina-angiotensina foram os medicamentos mais consumidos. CONCLUSÕES: Houve maior consumo de medicamentos entre as pessoas com deficiências quando comparados com os não-deficientes, sendo os indivíduos com deficiência física os que mais consumiram fármacos, seguidos de deficientes visuais e auditivos.

Este artigo faz uma reflexão sociológica das mudanças mais marcantes nos padrões e experiências da maternidade contemporânea, com base em estudos e pesquisas existentes, buscando situar o debate que tem sido construído em torno desse processo. Pressupõe que a escolha da maternidade é um fenômeno moderno consolidado no decorrer do séc. XX com o avanço da industrialização e da urbanização. Com mais acesso à educação formal e à formação profissional, as mulheres vão ocupar o espaço público, mantendo a responsabilidade da criação do(a)s filho(a)s, o que fez a maternidade se tornar uma escolha reflexiva, possibilitada pela contracepção (e concepção) moderna. Entretanto, essa escolha é marcada pelas relações de classe, de raça/etnia e de gênero. Conclui que estamos vivendo um período de transição para um novo modelo de família e maternidade, cujo substrato é o ideal de eqüidade na responsabilidade parental que, apesar dos avanços, ainda está longe de ser alcançado.

Los efectos de la prostaglandina (PGF2α) vs CIDR y eCG (gonadotrofina coriónica equina) en la dinámica de la población folicular y su relación con las concentraciones plasmáticas de P4 fueron investigadas en ovejas cíclicas. Fueron utilizadas 14 hembras ovinas de la raza Bergamascia; el Grupo 1 (Gl) se sometió a dos aplicaciones de PGF2α, y, el Grupo 2 (G2) tratado con CIDR durante 14 días siendo que, en el momento de su retirada, se administraron 500 UI de eCG. La dinámica folicular ovárica fue monitoreada por medio de ecógrafo. Se monitorearon todos los folículos ≥ mm y se gráfico su posición diariamente, observándose el desarrollo individual folicular. Desde el día anterior a la aplicación de la segunda dosis de PGF2α, (Gl) y desde la administración de eCG (G2) hasta el décimo día del ciclo estral se colectaron muestras de sangre para el análisis de P4. Hubo diferencia significativa (P<0,001) en las concentraciones plasmáticas de P4 entre los tratamientos. La sincronización del estro y ovulación utilizando CIDR + 500 UI de eCG, incrementó la cantidad de folículos reclutados, además de aumentar el diámetro máximo y la tasa de crecimiento de los folículos grandes en la primera onda folicular. En consideración a los resultados se puede concluir que la sincronización del estro y de la ovulación en hembras ovinas, utilizando el CIDR y 500 UI de eCG, incrementa la cantidad de folículos reclutados, además de aumentar el diámetro máximo y la tasa de crecimiento de los folículos grandes. La asociación CIDR+500 UI de eCG provoca aumentos significativos en las concentraciones plasmáticas de progesterona (P4) al inicio de la fase luteal en hembras ovinas.

Assim como, as vivências nos intercâmbios internacionais podem e devem contribuir em grau elevado na constituição das mesmas políticas públicas, angariando recursos e investimentos externos, elas também podem se aprofundar em experiência de conscientização dos sujeitos políticos. Quanto mais a difusão cultural entre os povos é incentivada, pelos governos e iniciativas não governamentais, somada à atividade política dos sujeitos, mais trará contribuições aos entremeios das sociedades complexas, que por sua vez, refletirão na melhoria das condições de vida dos indivíduos e de suas instituições. O plano discursivo ideal propõe a superação das amarras econômicas para contemplar os estratos sociais, essa seria a primeira etapa para iniciar o aperfeiçoamento das instâncias democráticas e, convém assistir às transformações desde as estrutura, ou seja, dos modos de pensar, ser e agir dos seres humanos em busca de um novo tipo de desenvolvimento, que de fato se reconheça globalizado. Para tanto, o método utilizado se ancorou na revisão bibliográfica da análise histórica e da análise de discursos dos ex-presidentes, a partir da época de redemocratização brasileira. A todo o momento, frisou-se a articulação entre as mais diversas frentes de organização social, interna e externa, bem como as supranacionais, tal articulação é oportuna à metodologia, na tentativa de uma compreensão introdutória dos processos da modernidade complexa. Além disso, optou-se por tecer considerações finais que deixassem o texto aberto ao debate, ao contrário de qualquer proposta conclusiva. A saber, a potencialidade em dialogar sobre o conceito de desenvolvimento, que se deseja pluralmente inserido na universalidade relativa ao gênero humano, torna-se mais atraente, à medida que são cobradas melhorias dos programas político-democráticos...

Underdeveloped nations have the largest absolute number of the world's elderly population. Approximately 10.7% of the Brazilian population comprises aged individuals. Aging populations are associated with a higher incidence of chronic degenerative diseases such as dementia. Demented individuals place a high burden of care on healthcare systems and family members. General practitioners should be able to diagnose the most common elderly diseases such as dementia since they act as gatekeepers to specialized care. In Brazil, many medical students work as general practitioners upon graduating. The present study shows some scenarios of medical schools worldwide, including Brazilian, regarding teaching on dementia.

Objectives. To research parental behavior and measure the weight of Nelore and Guzerat calves up to 120 days of age, collecting data from birth up to the first lactation. Materials and methods. Seven different corporal positions were considered to obtain specific data for each of the following categories: time to stand (TP), time to intend to feed after standing (TPTM), weight at birth (PN), weight at 120 days (P120), and time in contact with the calf (TCC). Additionally, independent variables were also evaluated, organized by class: weight at birth (CPN), number of calvings (CNP), order of calving in relation with the herd (CLPR), time of calving (CHP), and finally, hindering to feed (CTAT). Results. There was a significant result in favor of the Nelore race over the Guzerat race. The statistical averages for Nelore and Guzerat were: Time to stand averaged 71 and 153 minutes; time to intend to feed after standing, 39 minutes for Nelore and of 114 minutes for Guzerat. For variable weight at 120 days, Nelore reached an average of 122 kg, and Guzerat 109 kg. For the time in contact with the calf variable there was no significant variance between races. Conclusions. Results showed the superiority of the Nelore race, considering it better adapted to local environmental conditions.

The objective was evaluate the phenotypic correlations among visual scores, performance traits and scrotal circumference of the polled Nelore cattle performance tests. Animals of the fifth, sixth, seventh official performance test in pasture were analysed. At the end of each test period the following measures were taken: adjusted weight to 550 days, gain weight, visual score (body structure; precocity and muscle) and scrotal circumference. The musculature, precocity and body structure showed significant positive correlations (P <0.01) with gain weight, adjusted average daily weight to 550 days, scrotal circumference and chest circumference. However, only hip height showed a significant positive correlation with muscularity. Therefore, in polled Nelore cattle, regards to performance test in pasture, the visual scores show positive correlation with the performance traits and scrotal circumference, showing that visual scores is important tool in the polled Nelore Cattle performance test.

The sheep industry has become increasingly prominent in agribusiness, transforming the stage production of Brazil, and thus contributes more to the socio-economic development of the country. The work aimed to verify the occurrence of brucellosis and leptospirosis in sheep from northwestern São Paulo state. In addition to determining the prevalence of major Leptospira in the region and to trace the diagnosis of sheep breeding in this part of the country. All the 1222 sheep serum samples from 49 properties did not react serologically to evidentiary testing for brucellosis, compared to antigens of B. abortus and B. ovis used in the testing of 2-ME and IDGA, respectively. The Microscopic Agglutination Test (MAT) test revealed that 19.14% (232/1212) of samples were positive for one or more serovars, with titles ranging from 100 to 800. The most frequent serovar was hebdomadis in the region, with Sentot and Sherman (18.10%, 11.64% and 8.62%, respectively). By profiling the system of sheep farming in the region, we found that most herds are composed of more than one race being the main purpose is for the court. According to the scheme adopted immunoprophylactics there is a homogeneous set schedule. It adopts the use of anti-helminth, non-prescription veterinary antibiotic. There is also the presence of diarrhea and abortions and the lack of criteria for los ovinos on management, making it the need for emergency development of programs for disease control, schema immunoprophylactics adequate sanitation and hygienic measures in sheep breeding.

The objective of this study was to investigate the influence of lineage of oocytes donors on the number and quality of oocytes obtained through ultrasound-guided follicular aspiration in Nellore breed cows derived from two lineages of bulls (Karvadi; K and Taj-Mahal; T). Both maternal (Km and Tm) and paternal (Kp and Tp) lineages, as well as their combinations were investigated. Oocyte aspirations were repeatedly performed with an aspiration interval of 15 days in 56 donor females. Recovered cumulus oocyte-complexes (COCs) were counted, morphologically examined and classified into seven categories (grades from I to VII) according to the number of layers of the cumulus oocyte and cytoplasm appearance. The mean number of oocytes retrieved from donors of lineage Tp-Tm was significantly higher (28.23±1.92, P<0.05) than those obtained from lineages Kp-Tm, Kp-Km, and Tp-Km (21.34±1.32, 21.28±1.73, and 16.72±1.31, respectively). There was no significant difference in the mean number of recovered oocytes between donors of lineages Kp-Km and Kp-Tm, whereas animals of lineage Tp-Km yielded the lowest number of oocytes. Higher mean number of grade III oocytes was recovered from donors of lineage Kp than lineage Tp (10.11±0.66 versus 8.79±0.58, respectively), with more grade III oocytes being obtained in both lineages as compared to the others. Paternal lineage did not influence the quality of recovered oocytes in any other category, but both Kp and Tp yielded a great mean number of oocytes graded as I, II, and III (3.14±0.21; 4.93±0.33, and 10.11±0.66 versus 3.19±0.21, 5.59±0.44, and 8.79±0.58, respectively) than those classified as IV, V, VI, and VII. However, when considering the data from the maternal lineage significantly more oocytes (P<0.05) of grade I, II and III were obtained from Taj-Mahal (11.67 ± 0.67, 5.9±0.42 and 3.64±0.25, respectively) than for lineage Karvadi, with similar results for oocytes of grades IV, V, VI, and VII. Similarly to the paternal lineage, the number of oocytes of grade III was superior (P<0.05) when compared to other categories for both lineages. In conclusion, we demonstrate here a direct influence of lineage of oocyte donor on the production and quality of oocytes obtained through ultrasound-guided follicular aspiration in Nellore cows.

Pets bring expressive benefits into the life of the elderly, so it becomes necessary to emphasize some of the concepts regarding responsible ownership consisting of a set of important attitudes that accounts for the well-being of all. In this context, non-governmental institutions represent an excellent mean of communication and information. Besides, the increase of the third aged people population indicates that a survey of parameters to this respect is necessary. Being thus, the objective of this work was to analyze the aged ones´ level of knowledge regarding their responsibility for their pet. A questionnaire was applied to 134 aged people, members of non-governmental organizations in the city of Araçatuba, SP, in order to find out how they took care of their pet animals. The pets aged from 2 to 336 months, being 43,3% mixed-breed animals. Out of that, 60,9% were male dogs and among cats, 65.2% were female cats. There was a 69.4% preference for dogs and a 17.9% preference for cats, only 10.5% of the elderly had preference for birds. From the descriptive statistics analysis it could be observed that 69.40% did not have any access to the street and that 50% did not have a veterinarian follow-up. Regarding vaccination it could be observed that 71.64% had received the rabies vaccine and 70.9% had received the combination vaccine. Also, 74.63% did not know the right moment to give medicines against animal worms. Another important fact was that 85.07% of the animals were not castrated and 84.91% were not under any preventive contraception method. In regard to food 50.75% of the animals were fed strictly with animal food, 12.69% with domestic food and 36.57% with both. Finally, 78.36% of the pets had never been ill. In this way, we can assure the importance of making responsible pet ownership measures well-known among third-aged people.

Since its arrival in Brazil at the beginning of the new century, queer theory – and particularly that variant of it linked to the works of Judith Butler – has been followed, criticized, contested and yet hardly problematicized in its deeper epistemological implications. Although Brazilian scholars have employed meanings and consistent debates regarding the changes that this axis of subaltern knowledge has provoked, there are still few discussions which seek to think about these contributions in the specific Brazilian context, in which categories of gender, sexuality, race and ethnicity link and cross in unique ways, creating experiences that are quite different from those generally discussed by foreign queer theorists. In the present article, I am trying to provoke an anthropophagic reflection, seeking fruitful dialogues with feminisms and post-colonial texts, emphasizing those that focus upon Latin-American reality, in an attempt create tension in our productions – thought in terms of local realities – as these face questions and issues that are also transnational. The idea here is to go beyond translating "queer", towards thinking of a theory informed by these productions, but which also dares to invent itself through questioning our own marginalized experience. In the present article, I look at the short but intense production of Argentine anthropologist Néstor Perlongher, taking it as one of the starting points for the elaboration of a Latin American (but mainly Brazilian) "teoria cu": that which is produced outside of the phallocentric and heteronormative regimes of canonic science.
