The buttonweed (Spermacoce latifolia) is becoming a plant among the most current infesting eucalypts plantation in State of São Paulo due to the continual use of same herbicides and control methods. Owing this, this work aimed to evaluate the effects of periods of company and control of S. Iatifolia on the initial growth of Eucalyptus grandis, planted in winter and summer. Only one seedling of Eucalyptus was planted in amianthus cement box and submitted for crescent periods of company and control of S. Iatifolia (0, 20, 60 and 80 days in competition or not). The densities of plants of S. Iatifolia were 4 and 16 plants per m 2 (under winner and summer conditions). The experimental period was 100 days after the planting (DAP). The experimental design for both experiments was the completely randomized blocks (CRB) with ten treatments and four replicates. The results of plant high, stem diameter, dries weights and leaf area showed that the before interference period (BIP), whole period of prevention for interference (WPPI) and critical period of prevention for interference (CPPI) were 40, 60, and 60 DAR, respectively, under winner conditions. Under summer conditions, the WPPI and CPPI were 20, 80 and 20 to 80 DAR.

A presente dissertação intitulada Desenvolvimento Local Sustentável como Liberdade: uma Experiência de Planejamento Estratégico do Grupo de Mulheres Erva Vida tem como objetivo principal analisar as perspectivas das participantes do grupo Erva Vida na discussão de estratégias que contribuam para o processo de desenvolvimento local sustentável. Alicerça seu arcabouço teórico, na apropriação do conceito de Instrumental Freedoms (IF’s) , discutidas por Amartya Sen (2000). São ao mesmo tempo o fim e o meio do processo de desenvolvimento. Estão entrelaçadas e se fortalecem à medida que são alcançadas. Essas liberdades instrumentais foram denominadas de political freedom; econômic facilities; social opportunities; transparency e guarantees e measures ensurig social protection and security. Para alcance dos resultados desta pesquisa, foram observados os aspectos internos e externos de uma organização social e análise das perspectivas de remoção de restrições a essas liberdades, a partir de uma experiência de Planejamento Estratégico conduzido junto ao grupo de mulheres Erva Vida, em Marapanim (PA). O grupo foi selecionado a partir de uma ação de economia solidária, desenvolvida pelo laboratório de Etnofarmácia, do Núcleo de Meio Ambiente da UFPA com uma associação de mulheres do bairro Sossego, no distrito de Marudá, em Marapanim (PA) envolvidas na produção de remédios artesanais. Considerando os resultados desta pesquisa, os produtos diretos constituem-se no documento de planejamento estratégico do grupo e num manual de orientação para facilitadores de planejamento local. Esses produtos podem contribuir indiretamente para o aperfeiçoamento das políticas públicas de desenvolvimento sustentável local na região amazônica, contribuindo, em linhas gerais, diretamente nas ferramentas para formulação de propostas para gestão de recursos naturais.

This work aimed to evaluate the carcass yields, commercial cuts and non-carcass components of Santa Inês lambs fed with 30, 40, 50 or 60% of oldman saltbush hay with concentrated. Were used 32 castrated lambs at 8 months old and initial body weight of 22 + 1.97kg, housed individually and slaughtered after 60 days of feedlot. The weights of hot and cold carcass decreased linearly with the inclusion of saltbush hay in the diet, however, there was no effect for true carcass yield and commercial cuts: shoulder (19.26%), neck (8.52%) ribs (26.57%) and leg (33.88%). There was a linear decrease for ribeye area and fat thickness when the level of hay in the diet increased. The weights and yields of skin, liver, heart, kidneys with perirenal fat, omental and mesenteric fats decreased linearly with the inclusion of hay in the diet, while the content (%) of gastrointestinal tract increased. The increased proportion of saltbush hay in the diet of lambs provided adequate true carcass yield and commercial cuts, however, reduces the ribeye area and fat thickness, important measurements in the qualitative evaluation of the lamb's carcass.

Introduction: Physical exercise are related to high oxygen consumption, leading to increase on reactive oxygen species (ROS) generation and subsequent oxidative stress. Concomitantly, physical training can improve the antioxidant defense systems, reducing the deleterious activity of ROS. The yerba mate (Ilex paraguariensis) has several bioactive compounds in its composition, providing important antioxidant activity in improving defense systems and reducing the damage caused by ROS. Few studies related to yerba mate with antioxidant effects during exercise. Objective: Evaluate whether the consumption-based drink yerba mate (Ilex paraguariensis) is able to increase the total antioxidant performance (TAP) after an exhaustive test on a treadmill. Methods: The sample counted with 15 female soccers players from Botucatu-SP female soccer team with a mean age of 22.1 ± 4.2 years. For laboratory tests , it was evaluated: triglycerides (TG), total cholesterol (TC) and fractions, glucose and gamma-GT were dosed by dry chemistry (Vitros® System, Johnson & Johnson). LDL-cholesterol was obtained by Friedwald formula. Total antioxidant performance (TAP) was obtained by the method of fluorescence assay for the measurement of plasma. Weight, height and body mass index (IMC) were measured, percentage of body fat was obtained by bioeletrical impedance analysis (Biodinâmics, modelo 450, USA). Arterial blood pressure was checked by auscultatory method and cardiorespiratory fitness was determined by ergoespirometric test (Ramp Protocol). Maltodextrin was supplemented (30 g in 400 ml) 30 minutes after M0 with placebo (400 ml) or mate (5 g in 400 ml of water). Statistical analysis: ANOVA for repeated measures followed by Tukey's test set, p<0.05. Results: There was a decrease in the pH after exhaustive testing for water and tea (p<0.0001), the same was observed for bicarbonate (p<0.0001). In both groups pO₂ increased for ...

O Brasil possui um enorme potencial de plantas medicinais usadas popularmente e ainda pouco estudadas pela comunidade científica. Dentro da família Polygonaceae, destaca-se a espécie Polygonum punctatum Ell., conhecida popularmente como erva-de-bicho, acataia, cataia, capiçoba, pimenta-do brejo ou pimenta-da-água. Essa espécie é perene e encontrada em lugares úmidos ou inundados, desenvolvendo-se preferencialmente em solo de boa fertilidade, areno-argiloso ou argiloso e com bom teor de matéria orgânica. É originária da Ásia e encontra-se aclimatada no Brasil em todos os Estados, particularmente no Rio Grande do Sul, Sul e Sudeste (LOPES et al., 2003). Há relatos de que na medicina popular faz-se o uso de todas as partes da planta para as mais diversas finalidades, tais como: antidisentérica, antisséptica, detersiva, diurética, antitérmica, anti-reumática, vermífuga e excelente cicatrizante de feridas e úlceras. E que por ser fortemente emenagoga e abortiva, seu uso não é recomendado para gestantes (MORGAN, 1984). Dentre as propriedades terapêuticas relatadas, destaca-se também o uso no tratamento de problemas circulatórios, visto que ela estimula a circulação e diminui a fragilidade capilar, e que por isso, apresenta um efeito hemostático bastante útil no tratamento de hemorróidas (TESKE e TRENTINI, 1995). No entanto, plantas medicinais utilizadas popularmente necessitam de estudos científicos que comprovem sua eficácia, segurança e qualidade. A espécie Polygonum acre H.B.K. (sinonímia de Polygonum punctatum Ell) possui poucos estudos científicos comprovando essa vasta utilização na medicina popular, sendo assim, se faz necessário estudar atentamente seus extratos e óleos essenciais, bem como associar a estes, estudos fitoquímicos e de identificação anatômica e morfológica para que não haja problemas que comprometam a qualidade e a eficácia...

The yerba mate (Ilex paraguariensis) is composed of bioactive that interfere with lipid metabolism. The objective was to evaluate if daily consumption of mate tea (MT) change the lipid deposits and dyslipidemia caused by excessive consumption of sucrose. Thirty male Wistar rats (40 days old) were divided into four groups: Group C - free access to commercial chow and deionized water; S - free access to commercial food, water and sucrose solution 30% (w/v) in water; MTS and deionized - free access to commercial feed solution, water, 30% sucrose (w/v) and treated with daily infusion of MT (soluble mate Leão Júnior®) via orogastric tube at a dose of 100 mg/kg/mc for 8 weeks. After the trial period the lipid profile was evaluated by the following parameters: a) direct weighing of the retroperitoneal (RP) and epididymal (EPI) adipose tissues; b) determination of plasma total cholesterol, triglycerides and HDL cholesterol concentration. The MT promoted the reduction of 1.4 times in both tissues RP and EPI in MTS group compared to group S. Treatment with MT decreased 2.7 times triglyceride in the MTS group compared with the group S. The sucrose consumption did not alter the plasma cholesterol concentration, however the consumption of MT significantly reduced total cholesterol circulating. The HDL cholesterol concentration, in the MTS group, showed higher concentration than in group S (1.3 times). MT prevents in young male rats the increase of lipid deposits and dyslipidemia caused by excessive consumption of sucrose.
