Crescimento e nutrição mineral de Urochloa arrecta

The experiment was carried out aiming to analyze dry mass production and distribution, and the content and accumulation of macronutrients in Urochloa arrecta plants cultivated under mineral nutrition standard conditions. Plants grew in seven-liter pots filled with sand substrate, were daily irrigated with nutrient solution, and maintained under greenhouse conditions. Treatments corresponded to assessment periods (21, 35, 49, 63, 77, 91, 105, 119, 133, 147, and 161 days after emergence - DAE) and were arranged in a completely randomized design with four replicates. Plants of U. arrecta showed low accumulation (less than 7% of the maximum accumulation at 161 DAE) of dry mass (5.1 g DM per planta) and of macronutrients (57.7 mg N per planta, 8.9 mg P per planta, 167.8 mg K per planta, 21.3 mg Ca per planta, 14.7 mg Mg per planta, and 9.2 mg S per planta) up to 49 DAE. Such accumulations increased mainly after 91 DAE. Daily accumulation rate was crescent up to 130 DAE (DM and S), 137 DAE (N), 125 DAE (P), 119 DAE (K), 144 DAE (Ca), and 128 DAE (Mg), when there was accumulation of 87.7 g DM per planta, 918.0 mg N per planta, 105.8 mg P per planta, 1,643.9 K per planta, 390.4 mg Ca per planta, 200.0 mg Mg per planta, and 103.5 mg S per planta. K and N were found to have the highest rates and, hence, they were the most demanded and accumulated in the greatest amounts in U. arrecta plant tissues.

Avaliação do potencial de utilização de percolado bruto e tratado fotoeletroquimicamente de aterro sanitário no desenvolvimento da espécie Helianthus annuus L

Os processos de decomposição dos resíduos sólidos resultam em uma importante fonte de poluente tóxico, o percolado, usualmente denominado de chorume, podendo causar graves impactos ambientais em ecossistemas vizinhos, se não for drenado e tratado adequadamente. No tratamento eletrolítico de efluentes aquosos, os poluentes sofrem degradação oxidativa. Visando o tratamento do percolado de aterro sanitário, foram analisados os parâmetros de pH, temperatura, DQO, condutividade, amônia e absorbância, utilizando-se de uma densidade de corrente de 125 mA.cm-2. As regas na espécie Helianthus annuus L., girassol da família Asteraceae, foram realizadas durante 95 dias com 11 tratamentos do percolado bruto e tratado em concentrações de 25, 50, 75 e 100% de percolado com a adição de Na2SO4, esta última concentração também sem adição de Na2SO4, a fim de avaliar a sobrevivência e o crescimento dessa espécie. Ao final do experimento, os valores de crescimento mais expressivos foram para o percolado 100% sem Na2SO4 mostrando que: a altura total obteve uma diferença em 27% menor no tratado; o diâmetro da base do caule mostrou uma diferença 45% menor do tratado em relação ao bruto; o número de folhas foi de 65% menor e área foliar de 51% menor do tratado em relação ao bruto, indicando que mesmo em crescimento o Grupo Tratado permaneceu menor durante a maioria das medidas das variáveis biométricas do girassol BRS 323. Todos os vasos regados com chorume tratado tiveram uma redução no peso seco das partes aéreas, chegando a uma redução média de 72% na concentração 100% de chorume sem a adição de Na2SO4

Angiogênese, vascularização e uso do ultrassom Doppler colorido como ferramenta de avaliação das estruturas ovarianas

Angiogenesis occurs as a physiologic process and is essential for normal growth and development of tissue. The ovary and its structures need adequate vascular network to ensure the availability of oxygen, nutrients, hormones, substrate, and ensure the transfer of different hormones to target cells. Then, the proper formation of this network is a limiting step for the proper functioning of this organ in general. In recent years, the local blood flow of the ovary, has been examined by color Doppler ultrasound, being able to analyze the individual follicles and the corpus luteum. This review will board the relevant aspects of the restructuring vascular ovary during the estrous cycle in female domestic large.

Avaliação da eficácia dos biocurativos em ratos wistar com lesões de pele causadas por queimaduras

Accidents caused by thermal, chemical, electrical or radioactive agents cause skin lesions causing burns of varying degrees. The therapeutic approach aims to restore damaged tissues and involves a wide range of products on the market. This study aims to evaluate the use of biological dressing, biotech product developed at the Blood Center of Botucatu / UNESP obtained from fresh frozen plasma or platelet concentrate with in vitro addition of thrombin and calcium gluconate. This addition in the platelet concentrate, intended to release the active growth factors of the platelets granules on the healing process. The study of the effectiveness of Platelet Gel home made in Wistar rats was established, in agreement with scald burns, comparing efficacy and cost of Platelet Gel with usual hospital -based treatment collagenase + chloramphenicol plus cost analysis through pharmacoeconomics. We used 25 Wistar rats were divided into 3 treatment groups: Group A, Collagenase + Chloramphenicol; Group B, Platelet Gel and C, control. The products were applied every other day for 30 days in animals. In group A, there was the presence of erythema and crust in all animals. The exudates was indentified 2/10 animals. For the Group B, we observed the presence of erythema and crust at all and no presence of exudates. In group C all the animals showed erythema with no presence of exudates and scab occurred in 1/10. Statistical analysis showed significant difference ( p < 0.0 ) for crust formation between Groups B and C. In the histological analysis, group A showed a slight amount of blood vessels and collagen fibers, moderate amounts of macrophages and fibroblasts was observed while B and C groups showed moderate amounts of blood vessels, macrophages and fibroblasts and discreet presence of collagen fibers. The re-epithelialization occurred in most animals of all groups without significant statistical differences. For the aspects of pharmacoeconomics, the platelet gel presented a better cost - effectiveness in relation to treatment based on collagenase / chloramphenicol. In light of the ethical aspects of the raw material is the result of spontaneous blood donation, the proposal should have biological dressings productions the responsibility of public blood transfusion centers for free distribution. This may point to the production chain of Brazilian blood banks like special blood components for use no intravenous.

Avaliação do estado nutricional de mudas de Gonçalo Alves (Astronium Fraxinifolium)

The planting of seedlings, the establishment and maintenance of the natural regeneration process, or the combination thereof, are methods used in the recovery of degraded or disturbed environments, however, often require the addition of soil conditioners. This study aimed to evaluate the influence of conditioners, introduced in degraded soil on growth and nutritional status of Astronium fraxinifolium seedlings. To conduct the experimentation were used as degraded soil conditioner, ash from sugarcane bagasse (CZ) and macrophytes (MC), at the doses of 0, 15, 30 and 45 t ha-1 and 0, 16 and 32 t ha-1 respectively, which combined produced 12 treatments, with three replications, and for field installation, was used the experimental randomized block design. Astronium fraxinifolium (Gonçalo Alves) seedlings, native tree species in cerrado, were introduced in the experimental area and, after 12 months, were evaluated for leaf concentration of nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, boron, copper, iron, manganese and zinc (N, P, K, Ca, Mg, S, B, Cu, Fe, Mn and Zn, respectively). Seedlings and adult plants of A. fraxinifolium were collected in preserved cerrado reserve were also analyzed for nutrients foliar concentration to perform a comparative analysis. The leaves collection in the preserved cerrado and experimental area, was accompanied by soil sampling (0.0 - 0,20 m deep), which was analyzed for phosphorus, OM (organic matter), pH, K, Ca, Mg, Al+H (potential acidity), Al (aluminum), Cu, Fe, Mn and Zn. The results show that the applied residues contributed to raise the foliar concentration of Cu and Fe. The foliar concentration of nutrients was higher in A. fraxinifolium seedlings from preserved cerrado, except for B, which was similar between areas, besides Cu and Fe with higher levels in the seedlings from experimental area. The combined addition of residues (MC and CZ), led to increase the plants height and diameter. This...
