Resumo Introdução: A estimulação não-invasiva tem sido amplamente utilizada nos últimos 30 anos no estudo e no tratamento de um grande número de doenças neurológicas, incluindo distúrbios do movimento. Objetivos: Nesta revisão crítica, discutimos o embasamento científico do uso da estimulação não-invasiva em distúrbios do movimento e as evidências científicas dos principais ensaios clínicos realizados. Métodos: Um grupo de especialistas realizou uma revisão crítica abrangente da literatura a fim de analisar as principais aplicações da estimulação magnética transcraniana (EMT) e da estimulação transcraniana por corrente contínua (ETCC) em distúrbios do movimento. As classes de evidência e de recomendação foram descritas para cada doença. Resultados: Apesar da grande variabilidade da metodologia e baixo efeito clínico, a EMT é provavelmente eficaz para o tratamento dos sintomas motores e da depressão na doença de Parkinson. A eficácia em outros distúrbios do movimento ainda é incerta. A EMT é possivelmente eficaz para o tratamento da distonia focal da mão, do tremor essencial e da ataxia cerebelar. No entanto, é provavelmente ineficaz na redução dos tiques na síndrome de Tourette. Finalmente, a ETCC é provavelmente eficaz na melhora da marcha na doença de Parkinson. Conclusões: As evidências até o momento sugerem que a estimulação não-invasiva pode ser benéfica para o alívio de alguns sintomas em determinados distúrbios do movimento como a doença de Parkinson, o tremor essencial, a distonia e a ataxia. Os protocolos de aplicação e paradigmas de estimulação ainda precisam ser investigados em ensaios clínicos maiores, assim como os seus efeitos a longo prazo.

Abstract Background: Noninvasive stimulation has been widely used in the past 30 years to study and treat a large number of neurological diseases, including movement disorders. Objective: In this critical review, we illustrate the rationale for use of these techniques in movement disorders and summarize the best medical evidence based on the main clinical trials performed to date. Methods: A nationally representative group of experts performed a comprehensive review of the literature in order to analyze the key clinical decision-making factors driving transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS) in movement disorders. Classes of evidence and recommendations were described for each disease. Results: Despite unavoidable heterogeneities and low effect size, TMS is likely to be effective for treating motor symptoms and depression in Parkinson’s disease (PD). The efficacy in other movement disorders is unclear. TMS is possibly effective for focal hand dystonia, essential tremor and cerebellar ataxia. Additionally, it is likely to be ineffective in reducing tics in Tourette syndrome. Lastly, tDCS is likely to be effective in improving gait in PD. Conclusions: There is encouraging evidence for the use of noninvasive stimulation on a subset of symptoms in selected movement disorders, although the means to optimize protocols for improving positive outcomes in routine clinical practice remain undetermined. Similarly, the best stimulation paradigms and responder profile need to be investigated in large clinical trials with established therapeutic and assessment paradigms that could also allow genuine long-term benefits to be determined.

RESUMO O objetivo do presente trabalho foi avaliar a composição química, o perfil fermentativo e os parâmetros da degradação da fibra em detergente neutro de três silagens do resíduo da produção do palmito pupunha, sendo estas silagens de folha, bainha foliar e composta (55% de folha e 45% de bainha foliar). O resíduo foi acondicionado em silos experimentais e aberto após sessenta dias de fermentação com retirada de amostras das silagens para a determinação da composição química e dos parâmetros de degradação da fibra em detergente neutro nos tempos de 0, 3, 6, 9, 12, 24, 36, 48, 72 e 96 horas de incubação in vitro. Houve diferença no teor de matéria seca entre os três tipos de silagem, assim como para a proteína bruta, fibra em detergente neutro, fibra em detergente ácido e lignina. A silagem de folhas apresentou maior taxa de degradação fracional e maior fração potencialmente degradável da fibra em detergente neutro ao longo das 96 horas de incubação. Quanto aos parâmetros fermentativos, a silagem feita com a folha apresentou maiores valores de pH (3,79) e ácido lático (1,18%), ácido acético (0,39%) e ácido propiônico (0,24%). O ácido butírico foi maior para a silagem composta (0,012%) e o nitrogênio amoniacal foi maior para a silagem de bainha (0,94%). A silagem de folha apresentou melhores características químicas, parâmetros fermentativos e características de degradabilidade in vitro, demostrando ser a silagem com melhor valor nutricional para alimentação de animais ruminantes.

ABSTRACT The objective of the present work was to evaluate the chemical composition, fermentation profile, and degradation parameters of the neutral detergent fiber of three silages made with the waste from production of heart of peach of palm, which consisted of leaf, leaf sheath, and their compound (55% leaf and 45% leaf sheath). The waste was packed in experimental silos and open after sixty days of fermentation; silage samples were collected for determination of chemical composition and degradation parameters of neutral detergent fiber at 0, 3, 6, 9, 12, 24, 36, 48, 72, and 96 h of incubation in vitro. A difference was detected in the dry matter, crude protein, neutral detergent fiber, acid detergent fiber, and lignin contents between the three types of silage. The leaf silage showed a higher fractional degradation rate and a higher potentially digestible fraction of neutral detergent fiber over the 96 h of incubation. As for the fermentative parameters, silage made with the leaf showed a higher pH (3,79) and lactic acid (1,18%), acetic acid (0,39%) and propionic acid (0,24%). The butyric acid was higher for compound silage (0,012%) and ammoniacal nitrogen was higher for sheath silage (0,94%). The leaf silage displayed better chemical characteristics, fermentation parameters and in vitro degradability properties, proving to be the silage with best nutritional value for feeding ruminants.

ABSTRACT We aimed to evaluate the lactation curves, composition, and fatty acid profile of milk of lactating goats fed diets containing detoxified castor cake (DCC) by alkaline solutions during 150 days of lactation. Twenty-four Saanen and Anglo Nubian goats, approximately 17 months old (first lactation) and 43±2.97 kg body weight, were distributed in a completely randomized block design with eight replicates. Treatments consisted of three diets, one containing soybean meal (SM) and two others containing DCC, with calcium hydroxide [Ca(OH)2] and sodium hydroxide (NaOH). The lactation curves showed greater persistence of lactation in Saanen goats. There were significant effects of diets on the profile of some fatty acids present in the milk. We observed that the NaOH DCC diet led to an increase in desirable fatty acid content. Both Ca(OH)2 and NaOH DCC diets led to decreased milk production during the lactation period; however, the NaOH DCC diet led to high productive efficiency. Furthermore, NaOH DCC did not negatively affect the desirable fatty acid content, unlike Ca(OH)2 DCC. Diets formulated with detoxified castor decrease the production of milk from goats during lactation phase. It should be emphasized that milk produced by goats fed DCC diets does not contain unwanted waste.

ABSTRACT The objective was to evaluate the intake, digestibility, nitrogen balance, and metabolic profile of lactating goats fed diets containing detoxified castor cake (DCC) by alkaline solutions during 150 days of lactation. Twenty-four Saanen and Anglo Nubian goats, approximately 17 months old (first lactation) and body weights of 43±2.97 kg, were distributed in a completely randomized block design with eight replicates. Treatments consisted of three diets, one containing soybean meal (SM) and two others containing DCC, with calcium hydroxide [Ca(OH)2] and sodium hydroxide (NaOH). The diets significantly influenced the intake of dry matter (DM), crude protein (CP), ether extract (EE), neutral detergent fiber (NDF), and total digestible nutrients (TDN). We observed a higher dry matter intake (DMI) in goats fed SM, similar to that of goats fed Ca(OH)2 DCC. Intake of nutrients followed the same trend as DMI. There was no significant effect of diets on digestibility of DM, CP, EE, and NDF; however, we observed a significant effect of diets on the levels of nitrogen intake (NI) and urinary nitrogen (UN). The goats fed SM consumed a larger quantity of nitrogen, but all had the same nitrogen balance, indicating that goats fed DCC were more efficient. The diets did not influence renal and hepatic parameters. Inclusion of castor cake in the diet of goats in confinement is an attractive option, considering that goats fed DCC present lower feed conversion, and its use does not cause hepatic and renal alterations, suggesting that SM can be completely replaced.

RESUMO Objetivo: Vitamina D assumiu um papel central na pesquisa e tratamento da esclerose múltipla (EM). O objetivo deste estudo foi avaliar os níveis séricos de vitamina D de pacientes com EM e controles que residem em uma área tropical. Métodos: Foram analisados dados de 535 pacientes com EM e 350 indivíduos controle em 14 cidades próximas ao Trópico de Capricórnio. Resultados: O valor médio da determinação de 25-OH vitamina D foi 26,07 ± 10,27 ng/mL para controles e 28,03 ± 12,19 ng/mL para pacientes com EM. Não houve correlação entre os níveis de vitamina D e o grau de incapacidade ao longo da duração da doença. Conclusão: Pelo menos na região que cerca o Trópico de Capricórnio, os níveis séricos de vitamina D estão entre valores de 20 a 30 ng/mL tanto para controles quanto para pacientes com EM.

ABSTRACT Objective: Vitamin D has taken center stage in research and treatment of multiple sclerosis (MS). The objective of the present study was to assess the serum vitamin D levels of a large population of patients with MS and controls living in a restricted tropical area. Methods: Data from 535 patients with MS and 350 control subjects were obtained from 14 cities around the Tropic of Capricorn. Results: The mean serum 25-OH vitamin D level was 26.07 ± 10.27 ng/mL for the control subjects, and 28.03 ± 12.19 ng/mL for patients with MS. No correlation was observed between vitamin D levels and the disability of patients over the disease duration. Conclusion: At least for the region around the Tropic of Capricorn, serum levels of vitamin D typically are within the range of 20 to 30 ng/mL for controls and patients with MS.

Abstract: En | Text: En | PDF: En

ABSTRACT Eight rumen-cannulated steers were assigned to two 4 × 4 balanced Latin squares to evaluate degradability and kinetics of fiber particles from diets based on corn silage and supplements with or without addition of lipids. Dietary treatments were: only corn silage (T1), corn silage plus concentrate with no added lipids (T2), corn silage plus concentrate with added soybean oil (T3), and corn silage plus concentrate containing ground soybean seeds (T4). Kinetics of gastrointestinal transit of fibrous particles was evaluated based on chromium-mordanted fiber. Events of rumen degradation dynamics of fibrous carbohydrates were quantified using the in situ incubation procedure. The mixed models methodology from SAS was used to fit models and the Tukey test was used to compare means. The ruminal digestibility of fiber was lower in treatments T3 and T4 and, consequently, lower proportions of potentially digestible fraction of standardized fiber and higher proportions of indigestible fraction of standardized fiber for treatments T3 and T4 compared with T1 and T2 were observed. However, there were no differences in mean retention time of the rumen, total mean retention time, mean digestion time, and rumen fill among diets. Animals from T2, T3, and T4 showed higher dry matter intake, organic matter intake, and crude protein intake rates than animals receiving T1 diet, but there was no effect of the addition of lipid. Treatments did not differ regarding neutral detergent fiber intake. Animals from T1 had lower crude fat intake than animals from T2, which showed lower crude fat intake than those from T3 and T4. The addition of lipid to concentrate has no effect on passage rate, digestion rate, and intake, when a good quality roughage is used.

ABSTRACT The objective of this study was to simulate total dry matter intake and cost of diets optimized by nonlinear programming to meet the nutritional requirements of dairy does and growing doelings. The mathematical model was programmed in a Microsoft Excel(r) spreadsheet. Increasing values of body mass and average daily weight gain for growing doelings and increasing body mass values and milk yield for dairy does were used as inputs for optimizations. Three objective functions were considered: minimization of the dietary cost, dry matter intake maximization, and maximization of the efficiency of use of the ingested crude protein. To solve the proposed problems we used the Excel(r) Solver(r) algorithm. The Excel(r) Solver(r) was able to balance diets containing different objective functions and provided different spaces of feasible solutions. The best solutions are obtained by least-cost formulations; the other two objective functions, namely maximize dry matter intake and maximize crude protein use, do not produce favorable diets in terms of costs.

ResumoEste estudo foi realizado com o objetivo de determinar as digestibilidades aparente e estandardizada de fosfatos para suínos em fase de crescimento, empregando duas metodologias. Foram usados 42 machos castrados, mestiços, com peso inicial de 37 ± 1,1kg em delineamento de blocos casualizados, em esquema fatorial 2 x 7, com dois métodos de coleta: coleta total de fezes e uso de indicador (cinza insolúvel em ácido [AIA ]) × sete tratamentos, que consistiram de uma dieta controle (CTR); três dietas contendo fosfato na forma de pó (PP): PPA = CTR + fosfato pó A, PPB = CTR + fosfato pó B, e PPC = CTR + fosfato pó C; e mais três dietas contendo o fosfato microgranular (MP): MP15 = CTR + fosfato microgranular 15%, MP45 = CTR + fosfato microgranular 45% e MP75 = CTR + fosfato microgranular 75%). Os valores de 15, 45, e 75% correspondem à solubilidade em água dos fosfatos. Foram seis repetições, e o animal foi considerado como unidade experimental. Os coeficientes de digestibilidade estandardizada dos fosfatos avaliadas pelo método de coleta total, em valores percentuais, foram: PPA = 86,9, PPB = 84,9, PPC = 81,9, MP15 = 89,4, MP45 = 88,8, e MP75 = 92,6. Os coeficientes de digestibilidade total estandardizada dos fosfatos avaliados pelo método do indicador, em valores percentuais foram: PPA = 75,9, PPB = 75,4, PPC = 75,6, MP15 = 84,9, MP45 = 78,0, e MP75 = 79,4. Considerando as duas metodologias avaliadas no presente trabalho, os fosfatos microgranulares constituem a melhor alternativa para a alimentação de suínos em fase de crescimento.

AbstractThis study was realized with the objective to determine the apparent and standardized digestibilities of phosphates to pigs in growing phase, employing two methodologies. Forty-two crossbred barrows with an initial weight of 37 ± 1.1kg were used in a randomized-block design in a 2 × 7 factorial arrangement, with two collection methods: total fecal collection and the use of a indicator (acid insoluble ash [AIA]) × seven treatments, which consisted of a control diet (CTR); three diets containing phosphate in powder form (PP): PPA= CTR + powder phosphate A, PPB= CTR + powder phosphate B, and PPC= CTR + powder phosphate C; and another three diets containing the microgranular phosphate (MP): MP15= CTR + microgranular phosphate 15%, MP45 = CTR + microgranular phosphate 45% and MP75= CTR + microgranular phosphate 75%). The values of 15, 45, and 75% correspond to the water-solubility of the phosphates. There were six replicates, and the pig was considered as experimental unit. The standardized digestibility coefficients of the phosphates assessed by the total collection method, in percent values, were: PPA = 86.9, PPB = 84.9, PPC = 81.9, MP15 = 89.4, MP45 = 88.8, and MP75 = 92.6. The standardized-digestibility coefficients of the phosphates evaluated by the indicator method (AIA) in percent values were: PPA = 75.9, PPB = 75.4, PPC = 75.6, MP15 = 84.9, MP45 = 78.0, and MP75 = 79.4. Considering the two methodologies evaluated in the present work, the microgranular phosphates constitute the best alternative for feeding pigs in the growth phase.

O objetivo deste trabalho foi avaliar o efeito de diferentes arranjos de plantio próprios para o consórcio com a atividade agrícola e pecuária, bem como tipos de consórcio na produção de plantas de pinhão manso em duas safras. O experimento foi realizado no município de Coronel Pacheco, Minas Gerais, em delineamento em blocos ao acaso, em esquema de parcelas subdivididas, sendo a parcela representada por 5 espaçamentos: 6x3m (555 pl ha-1); 12x(2x2)m (714 pl ha-1); 10x(2x2)m (833 pl ha-1); 8x(2x2)m (1.000 pl ha-1); 6x1,5m (1.111 pl ha-1) e a subparcela representada por dois tipos de consórcio (integração lavoura-pecuária-pinhão manso - iLPF, e integração pecuária pinhão manso - SSP). As avalições contemplaram as safras 2010/2011 e 2011/2012. Os resultados demonstraram que o maior espaçamento de plantio (6x3m) apresentou efeito positivo na produção por planta, superando os demais tratamentos. Não foram observados efeitos significativos no número de sementes por fruto, bem como no peso da semente. A produção por hectare, foi maior no espaçamento 6x1,5m (maior densidade populacional), entretanto não seguiu uma tendência linear. O sistema iLPF apresentou efeito significativo na produção, superando o sistema SSP

The objective of this research was to evaluate the effect of different spacing plantings and intercropping models on physic nut trees yield in two harvest seasons. The experimental trial was carried out in Coronel Pacheco, Minas Gerais, in a randomized complete bocks design, in a split-plotted scheme. The experimental unit was represented by 5 different spacing plantings 6x3m (555 pl ha-1); 12x(2x2)m (714 pl ha-1); 10x(2x2)m (833 pl ha-1); 8x(2x2)m (1,000 pl ha-1); 6x1,5m (1.111 pl ha-1) and the sub-unit by two intercropping models (crop-livestock-forestry - iLPF, and livestock-forestry - SSP). The evaluation period contemplated 2010/2011 and 2011/2012 harvest seasons. The results showed that the higher spacing planting (6x3m) had a positive effect on individual tree yield, overcoming the others. No effect was observed for number of seeds per fruit and seed weight. The yield per hectare was higher in the closest spacing planting (6x1.5m), however it did not follow a linear trend. The iLPF system affected yield positively, overcoming the SSP system

O objetivo deste estudo foi avaliar os efeitos de diferentes fontes de fósforo sobre o desempenho, peso de órgãos e parâmetros sanguíneos de suínos. Foram utilizados 112 suínos com peso inicial de 28,65±2,82kg distribuídos em blocos casualizados, em esquema fatorial 8 x 2 (oito fontes de fósforo x dois sexos), com quatro repetições para machos e três para fêmeas com dois animais por baia. Os suínos foram alimentados com dietas contendo:fosfato bicalcico (FBC); fosfato monobicalcico (FMB); superfosfato triplo (ST); superfosfato simples (SS), fosfato de rocha Catalão (ROCHA), mistura de fontes (MIS), ácido fosfórico (AF) ou dieta sem suplementação com fonte de fósforo (CONT). Aos 60 e 90 kg todos os suínos foram pesados e amostras de sangue fora coletadas para determinação da atividade de fosfatase alcalina (AFA), cálcio (Ca) e fósforo (P) e um animal por baia foi sacrificado para pesagem de fígado e rins e avaliação de rendimento de carcaça. A dieta CONT reduziu ganho de peso e consumo, piorou a conversão alimentar e aumentou peso relativo de rins, AFA e Ca, e diminuiu fósforo sanguíneo. As fontes FBC, FMB, ST e AF reduziram AFA e mantiveram constante P e Ca no sangue. Concluiu-se que fontes de fósforo ST, SS, ROCHA e MIS geraram níveis similares de AFA em suínos de 30 a 90kg que a dieta sem fonte inorgânica de P sem afetar seu desempenho.

The objective of this study was to evaluate the effects of different sources of phosphorus on performance, organ weight and blood parameters of pigs. One hundred and twelve pigs with body weight 28.65±2.82kg were distributed into randomized blocks, in a 8 × 2 factorial scheme (eight sources of phosphorus × two sexes), with four repetitions for males and three for females, with two animals per pen. The pigs were fed diets containing: dicalcium phosphate (DCP); monodicalcium phosphate (MCP); triple superphosphate (TS); single superphosphate (SS), Catalão-rock phosphate (ROCK), mix of sources (MIX), phosphoric acid (PAc) or a diet without any supplemental source of phosphorus (CONT). At 60 and 90kg, all pigs were weighed and blood samples were collected to determine alkaline phosphatase activity (APA), calcium (Ca) and phosphorus (P) and one animal per pen was killed to weigh the liver and kidneys and evaluate carcass yield. The use of diet CONT reduced the weight gain and feed intake, worsened feed:gain ratio and increased the relative weight of the kidneys, APA and Ca, and decreased blood P. The sources DCP, MCP, TS and PAc reduced the APA and maintained the P and Ca in the blood constant. Phosphorus sources TS, SS, ROCK and MIX generate similar levels of APA in pigs from 30 to 90kg to the diet without inorganic source of phosphorus without affecting their performance.

Este trabalho objetivou determinar o efeito do plantio de eucalipto no carbono orgânico total, na biomassa microbiana e na matéria orgânica leve na região do Cerrado, no sul do Piauí. O estudo foi desenvolvido utilizando-se amostras de solos provenientes de povoamentos de Corymbia citriodora com quatro anos e Eucalyptus urophilla com cinco anos, e de uma área de cerrado preservada (testemunha). As práticas de manejo dos plantios de eucalipto promovem a oxidação da matéria orgânica leve, resultando em maior teor de carbono orgânico do solo em relação ao cerrado preservado. A biomassa microbiana do solo nos plantios de eucalipto apresentou pouca eficiência na manutenção do carbono em comparação ao cerrado preservado.

This study investigated the effect of eucalyptus plantations in the total organic carbon, microbial biomass and light organic matter from the cerrado in the south region of the State of Piaui. The study was carried out utilizing soil samples from four-year-old Corymbia citriodora and five-year-old Eucalyptus urophilla stands and a preserved cerrado area (control).The management practices of eucalyptus plantations promoted the oxidation of the light organic matter result in gin higher content of soil organic carbon in relation to the preserved cerrado area. The soil microbial biomass in eucalyptus plantations presented low efficiency in the maintenance of carbon compared to the preserved cerrado.

O objetivo deste trabalho foi avaliar a capacidade de restabelecimento de pastagem de grama-estrela-africana (Cynodon nlemfuensis) após aplicação do herbicida glifosato, na pré-semeadura da cultura do milho. Utilizou-se o delineamento experimental de blocos ao acaso, com quatro repetições. Os tratamentos foram: doses do equivalente ácido (e.a.) do herbicida glifosato (0, 720, 1.440, 2.160, 2.880 e 3.600 g ha-1) e a testemunha capinada. A grama-estrela-africana é tolerante às doses normalmente recomendadas do herbicida (720 a 1.080 g ha-1 de e.a). Doses de glifosato de 1.232 a 1.439 g ha-1 de e.a. suprimem a grama-estrela-africana, evitam sua competição com a cultura do milho, e permitem a recuperação da pastagem após a colheita do milho.

The objective of this work was to evaluate the recovery capacity of African star grass (Cynodon nlemfuensis) after glyphosate application in pre-sowing of corn. A randomized block design was used, with four replicates. The treatments were doses of acid equivalent (a.e.) of the herbicide glyphosate (0, 720, 1,440, 2,160, 2,880, and 3,600 g ha-1) and a hoed control. African star grass is tolerant to the usually recommended doses of the herbicide (720 to 1,080 g ha-1 a.e.). Doses of glyphosate, ranging from 1,232 to 1,439 g ha-1 a.e. suppress the grass, avoid its competition with corn, and allow the recovery of the pasture after the corn harvest.

O objetivo deste trabalho foi avaliar a suscetibilidade diferencial de espécies de Urochloa ao herbicida glifosato. Dois experimentos foram implantados na Embrapa Gado de Leite, em Juiz de Fora, MG. O primeiro experimento foi realizado em vasos dispostos em bancadas, em ambiente aberto, e o segundo em campo. Em ambos os experimentos, adotou-se o delineamento experimental em blocos ao acaso, com parcelas subdivididas. Nas parcelas, foram semeadas três espécies de braquiária (U. brizantha, U. decumbens e U. ruziziensis) e, nas subparcelas, foram dispostas as doses do equivalente ácido do herbicida glifosato (0, 180, 360, 540, 720, 1.080, 1.440 g ha-1). Há variabilidade entre as espécies avaliadas de Urochloa, quanto à suscetibilidade ao herbicida glifosato, e U. ruziziensis é a mais suscetível. O conhecimento da suscetibilidade diferencial entre as espécies de Urochloa avaliadas permite uma economia de 12 a 16% na dose do herbicida glifosato.

The objective of this work was to evaluate the differential susceptibility of Urochloa species to glyphosate. Two experiments were carried out at Embrapa Gado de Leite, in Juiz de Fora, Minas Gerais state, Brazil. The first experiment was carried out in pots placed on benches in an open environment, and the second one in the field. A randomized block design arranged in split plot was used for both experiments. Three species of brachiaria (U. brizantha, U. decumbens and U. ruziziensis) were sown in the plots, and the subplots consisted of the glyphosate acid equivalent doses (0, 180, 360, 540, 720, 1,080, and 1,440 g ha-1). There is variability among the evaluated Urochloa species regarding glyphosate susceptibility, and U. ruziziensis is the most susceptible. The knowledge on the differential susceptibility among the evaluated Urochloa species allows for a saving from 12 to 16% herbicide glyphosate dose.
