Santa In?s crossbred lambs, managed in confinement and fed diets based on soybean oil, soybeans and a conventional diet, with or without the use of monensin (78 ppm dry matter basis) were evaluated. Thirty-six Texel ? Santa In?s lambs (18 males and 18 females) were managed in intensive systems. Animals were slaughtered after 87 days of confinement, and performance, carcass characteristics, weight and percentages of carcass and non-carcass components were evaluated. The animals fed the control diet had heavier carcass and parts than animals fed soybean, while the oil diet did not differ from the controls in most parameters. The animals fed soybean showed lower intake kg dry matter (DM), organic matter (OM), crude protein (CP), neutral detergent fiber (NDF) and metabolizable energy (ME) compared with animals fed the control diet, increased ether extract (EE) intake in kg, % body weight (BW) and metabolic weight (MW) and did not differ from the soybean oil diet. Animals receiving monensin had lower DM intake, OM, CP, EE, NDF, gross energy (GE) regardless of the expression, % kg BW, or % PM, than the animals that did not receive the additive. Males produced better and had heavier cuts than the females; the latter deposited subcutaneous fat earlier. Animals that received oil or soybean showed greater body weight and small intestine percentage. Soybean oil intake did not improve performance, carcass weights or parts of Santa Ines ? Texel lambs in confinement. Soybeans at 15% dry matter reduced energy intake and lamb performance. The use of monensin at 78 ppm on a dry matter basis is not recommended for lambs in confinement, especially if associated with oil or soybeans that may harm animal performance

O ensaio de desempenho foi realizado no Setor de ovinocultura da Fazenda Experimental do Moura, Curvelo-MG, da Universidade Federal dos Vales do Jequitinhonha e Mucuri. Foram utilizados 36 cordeiros, 18 machos inteiros e 18 F?meas, Santa In?s x Texel, terminados em sistema intensivo, alimentados com seis dietas: dieta controle (RC), ?leo de soja (OS), gr?o de soja (GS), controle com adi??o de monensina (RC+M), ?leo de soja com adi??o de monensina (OS+M) e gr?o de soja com adi??o de monensina (GS+M). Os animais foram abatidos ap?s 87 dias de confinamento, sendo avaliados o desempenho, as caracter?sticas de carca?a, os pesos e percentagens dos componentes da carca?a e n?o carca?a. O ensaio de digestibilidade foi realizado nas depend?ncias do Laborat?rio de Pesquisa Animal da Universidade Federal de Lavras, sendo utilizadas18 borregas Santa In?s com 6 meses de idade e 29kg, confinadas em gaiolas de metabolismo por 21 dias, sendo 14 dias de adapta??o de 7 dias de coleta de fezes, urina, sobras e amostras de ra??o. Os tratamentos foram constitu?dos das ra??es citadas acima, e no pen?ltimo dia do per?odo experimental realizou-se a coleta de sangue dos animais para avalia??o de constituintes sangu?neos indicadores do metabolismo energ?tico, prot?ico e fun??o hep?tica. Os dados foram avaliados pelo procedimento GLM do SAS, e as m?dias comparadas e analisadas pelo teste de t a 5% de probabilidade. Houve superioridade no desempenho, consumo e digestibilidade dos animais que receberam dieta controle em rela??o aos animais que receberam gr?o de soja, sendo que a dieta com ?leo n?o diferiu da controle na maioria dos par?metros analisados. Os animais que receberam monensina apresentaram menores coeficientes de digestibilidade, menor consumo de todos os nutrientes analisados, menor desempenho e apresentaram ind?cios de problemas hep?ticos. Os machos tiveram desempenho e cortes mais pesados que as f?meas. N?o se recomenda o uso de monensina a 78 ppm em base da mat?ria seca para cordeiros em confinamento. O ?leo de soja n?o melhorou o desempenho, consumo e digestibilidade das dietas e o gr?o de soja, adicionado em 15% na mat?ria seca da ra??o, piorou esse par?metros.Disserta??o (Mestrado) ? Programa de P?s-Gradua??o em Zootecnia, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2010.ABSTRACT There was conducted a study to evaluate the use of two fat sources and a control diet, combined with two monensin levels on lambs feed. The performance test was accomplished at a sheep industry sector of the Federal University of the Jequitinhonha and Mucuri Valleys in the Moura Experimental Farm, Curvelo-MG. The work evaluated 36 lambs, 18 males and 18 females, Santa In?s x Texel finished in feedlot and fed with six diets: control diet (RC), soybean oil (SO), soybean (GS), control with monensin addition (CR + M), soybean oil with monensin addition (OS + M) and soybean with monensin addition (GS + M). The animals were slaughtered after 87 days of confinement, being evaluated for performance, carcass characteristics, weights and percentages of carcass and not carcass components. The digestibility trial was conducted on the premises of the Animal Research Laboratory of the Lavras Federal University evaluating 18 Santa Ines lambs with 6 months of age and 29kg, confined in metabolism cages for 21 days, being 14 days for adaptation counting 7 days of collection of feces, urine, and samples of feed. The treatments consisted of the diets mentioned above, and one day before the end of the experiment there was collected animals blood sampling for blood constituents evaluation, which are indicators of energy metabolism, protein and liver function. The data were analyzed by GLM procedure of SAS and the average were compared and analyzed by t test for 5% of probability. There were higher in performance, intake and digestibility of pigs fed with the control diet compared to animals fed with soybean, and oil diet did not differ from controls in most parameters. The animals fed with monensin had lower digestibility, lower consumption of all nutrients, lower performance and showed signs of liver problems. Males had cuts and performance heavier than females. There are not recommended the monensin use at 78 ppm in dry matter basis for confined lambs. Soybean oil has not improved performance, intake or digestibility of diets and the soybean, added 15% in the dry matter, worsened this parameters

Percepções das crianças sobre as relações de gênero a partir das interações vividas entre pares e na companhia de uma professora e um professor na Educação Infantil

The article analyzes the perceptions of five-year-old children about gender relations experienced among themselves and in company of a female teacher and a male teacher in a Early Childhood Education school in Belo Horizonte, Minas Gerais. The theoretical-methodological framework aggregates feminist studies and gender studies in the proposition an ethnography with 7 five-year-old girls, 18 five-year-old boys, a female teacher and a male teacher in Early Childhood Education. The instruments of data production were participant observation, interviews and drawings articulated with the children's speeches. It was identified that the gender relations experienced within the peer group (intra-generational relationships) and in the company by the male teacher and the female teacher (intergenerational relationships) were perceived by the children. The conclusions of the study point to urgency for gender issues to appear in pedagogical projects of Early Childhood Education, especially when a male teacher works with children.O artigo analisa as percepções das crianças de cinco anos sobre as relações de gênero vividas entre si e na companhia de uma professora e de um professor em uma Unidade de Educação Infantil da Rede Municipal de Ensino de Belo Horizonte.

Os instrumentos de produção de dados foram: observação participante, entrevistas e desenhos articulados com as falas das crianças. Identificou-se que as relações de gênero vividas no interior do grupo de pares (relações intrageracionais) e na companhia de um professor e uma professora (relações intergeracionais) eram percebidas pelas crianças. As conclusões do estudo apontam para a urgência de as questões de gênero figurarem nos projetos pedagógicos da Educação Infantil, principalmente quando um professor homem atua junto às crianças

Equilíbrio e preocupação com quedas em idosas que praticam exercícios resistidos e aeróbio

Regular physical exercise is considered an effective method for preserving and improving balance in elderly women. However, it is unclear whether resistance and aerobic exercises have the same effect on balance in elderly women. With this in mind, the aim of this study is to compare the effects of resistance and aerobic training on balance and concern about falls in elderly women. For this purpose, elderly women from the resistance training group (RTG; n = 15) and the aerobic exercise group (AEG; n = 15) had their physical activity level, balance and concern about falls evaluated. No significant differences were observed between the groups in physical activity level (χ²= 0.240; gl= 1; p<0.624). However, the elderly women from the RTG showed better performance in the balance test (49.8±3.85) and low concern about possible falls (18.3±1.44), when compared to the elderly women from the AEG (balance: 28 .13±4.24; χ² Wald (1) = 176.778; p<0.0001; concern about possible falls: 33.0±5.93; χ² Wald (1) = 87.5; p<0.001). In view of this, we can conclude that elderly women who practiced resistance training showed better balance and less concern about possible falls compared to those who practiced aerobic exercises.A prática regular de exercício físico tem sido considera uma conduta eficiente para melhorar o equilíbrio de idosos. Porém, não está muito claro se os exercícios físicos resistido e aeróbio resultam no mesmo efeito sobre o equilíbrio em mulheres idosas. Pensando nisso, o objetivo deste estudo foi comparar os efeitos dos treinamentos resistido e aeróbio sobre o equilíbrio e a preocupação com quedas em idosas. Para tal, foram avaliadas idosas do grupo treinamento resistido (GTR; n = 15) e do grupo aeróbio (GEA; n = 15). Foram mensurados o nível de atividade física, o equilíbrio e a preocupação com a queda. Nenhuma diferença significativa entre grupos foi observada no nível de atividade física (χ²= 0,240; gl= 1; p<0,624). Porém, as idosas do GTR apresentaram melhor desempenho no teste de equilíbrio (49,8±3,85) e baixa preocupação com uma possível queda (18,3±1,44), quando comparadas com as idosas do GEA (equilíbrio: 28,13±4,24; χ²Wald (1) = 176,778; p<0,0001; preocupação com uma possível queda: 33,0±5,93; χ²Wald (1) = 87,5; p<0,001). No presente estudo, podemos concluir que idosas praticantes de treinamento resistido apresentaram melhor equilíbrio e menor preocupação com uma possível queda em relação às idosas praticantes de exercício aeróbio.A prática regular de exercício físico tem sido considera uma conduta eficiente para melhorar o equilíbrio de idosos.

Performance, carcass characteristics and non-carcass components of Texel × Santa Ines lambs fed fat sources and monensin

Performance, carcass, non-carcass and commercial cuts and components of Texel × Santa Inês crossbred lambs, managed in confinement and fed diets based on soybean oil, soybeans and a conventional diet, with or without the use of monensin (78 ppm dry matter basis) were evaluated. Thirty-six Texel × Santa Inês lambs (18 males and 18 females) were managed in intensive systems. Animals were slaughtered after 87 days of confinement, and performance, carcass characteristics, weight and percentages of carcass and non-carcass components were evaluated. The animals fed the control diet had heavier carcass and parts than animals fed soybean, while the oil diet did not differ from the controls in most parameters.

Anti-malarial activity and toxicity assessment of Himatanthus articulatus, a plant used to treat malaria in the Brazilian Amazon.

Background: Plasmodium falciparum has become resistant to some of the available drugs. Several plant species are used for the treatment of malaria, such as Himatanthus articulatus in parts of Brazil. The present paper reports the phyto-chemistry, the anti-plasmodial and anti-malarial activity, as well as the toxicity of H. articulatus. Methods: Ethanol and dichloromethane extracts were obtained from the powder of stem barks of H. articulates and later fractionated and analysed. The anti-plasmodial activity was assessed against a chloroquine resistant strain P. falciparum (W2) in vitro, whilst in vivo anti-malarial activity against Plasmodium berghei (ANKA strain) was tested in mice, evaluating the role of oxidative stress (total antioxidant capacity - TEAC; lipid peroxidation – TBARS, and nitrites and nitrates - NN). In addition, cytotoxicity was evaluated using the HepG2 A16 cell-line. The acute oral and sub-chronic toxicity of the ethanol extract were evaluated in both male and female mice. Results: Plumieride was isolated from the ethyl acetate fraction of ethanol extract, Only the dichloromethane extract was active against clone W2. Nevertheless, both extracts reduced parasitaemia in P. berghei-infected mice. Besides, a significant reduction in pulmonary and cerebral levels of NN (nitrites and nitrates) was found, as well as in pulmonary TBARS, indicating a reduced oxidative damage to these organs. The ethanol extract showed low cytotoxicity to HepG2 A16 cells in the concentrations used. No significant changes were observed in the in vivo toxicity studies. Conclusions: The ethanol extract of H. articulatus proved to be promising as anti-malarial medicine and showed low toxicity
