Revista Brasileira de Saúde e Produ??o Animal , 2010,
Abstract: This work determined the best economical combination between irrigation and nitrogen levels, the marginal rate of substitution among inputs and to evaluate inputs effects on black oat (Avena strigosa Shreb) forage quality. Irrigation was done using a line source sprinkler system. It was used a randomized complete block design for the irrigation variable, with the factor nitrogen, a split plot on irrigation and five replications. The eight irrigation levels applied were: 1.3, 107.1, 135.7, 295.9, 330.3, 469.7, 544.3 and 546.1mm. The six nitrogen doses were: 0.00, 0.02, 0.04, 0.08, 0.16, and 0.32Mg/ha. The rude protein content for the maximum economical dry matter yield was 17.6%. Considering input costs and output prices of black oat forage, it was calculated the maximum economical yield of 3.87Mg/ha of dry matter for 280mm of irrigation depth and for 0.094Mg/ha nitrogen level, which allowed a profit of R$147.32 per ha. The marginal rate of substitution was found to be 0.44mm water per 1x10-3Mg/ha of nitrogen. Maximum dry matter yield 4.22Mg/ha was verified for the 336mm irrigation depth and for 0.22Mg/ha nitrogen dose. Mean neutral detergent fiber values obtained were lower than 55%. Objetivou-se determinar a melhor combina o econ mica entre lamina de água e dose de nitrogênio, a taxa marginal de substitui o entre os insumos e avaliar o efeito da combina o dos insumos mencionados sobre a qualidade da forragem de aveia-preta (Avena strigosa Shreb). A irriga o foi feita por aspers o com linha única. O delineamento experimental foi o de blocos casualisados no esquema de parcela subdividida no espa o. As parcelas foram compostas pelas laminas de água, e as subparcelas, pelas doses de nitrogênio. As laminas de água aplicadas foram: 1,3; 107,1; 135,7; 295,9; 330,3; 469,7; 544,3 e 546,1 mm, e as doses de nitrogênio: 0,00; 0,02; 0,04; 0,08; 0,16 e 0,32Mg/ha. O teor de proteína bruta no nível de rendimento máximo econ mico de matéria seca de aveia produzida foi de 17,6%. A partir dos custos dos insumos e do valor da forragem de aveia-preta, o ótimo econ mico foi calculado em 3,87Mg/ha de matéria seca, obtido a um nível de 280 mm de lamina de água aplicada e de 0,094 Mg de nitrogênio por ha, o que proporcionou um lucro de R$147,32 por ha. A taxa marginal de substitui o foi calculada em 0,44mm de água por 1x10-3Mg/ha de nitrogênio. A máxima produtividade de matéria seca 4,22Mg/ha foi observada para a lamina de irriga o de 336 mm e dose de nitrogênio de 0,22Mg/ha. Os teores médios de fibra em detergente neutro ficaram abaixo de 55%.

Abstract: The aim of this study was to evaluate the visible loss of sugar cane and the damage to the knuckles, using the John Deere 3520 harvester on three different travel speeds (3.0; 4.0 and 5.0 km·h-1), in DIC with five repetitions in Campos dos Goytacazes, Rio de Janeiro/Brazil. Each treatment was composed by six lines of harvested cane stumps, with a length of 290 m each. In these six lines, the remains of sugar cane left in the field were collected by placing the sampling frame in two central lines every 50 m, and separating 40 m of edge. The sampling area was surrounded by 2 m wide and 10 m long, totaling 20 m2. To calculate the damage to stumps, a visual methodology by [1], was used, which classifies the damage grade, ranging from 1 to 4. Fifty stumps were assessed randomly for each speed, in a sampling area of 1800 m2. The data were submitted to ANOVA and Tukey test at 5%, in order to compare the effect of different speeds on the losses and damages. There was no significant difference regarding the loss or damage by comparing the different speeds. Therefore, it is more advantageous to use the speed of 5.0 km·h-1, harvesting more in less time and causing the same level of damage.

Abstract: The purpose of this preliminary study was to determine the comparative lipid profile of blood plasma samples of healthy individuals and patients with Myeloproliferative Neoplasms. Methods: Untargeted Shotgun MS/MS Analysis was performed to evaluate plasma samples from 153 participants, being 90 of the Control Group, 43 Myeloproliferative Neoplasms (MPN), 11 Myelodysplastic Syndromes (MDS) and 9 Acute Myeloid Leukemias (AML). Lipids were extracted from plasma using the Bligh-Dyer protocol. Data were acquired using the AB-Sciex Analyst TF, processed using the AB-Sciex LipidViewTM and the web-based analytical pipeline MetaboAnalyst 2.0 (www.metaboanalyst.ca). Results: Untargeted analysis identified in negative and positive-modes a total of 658 features at 2 ppm resolution. PCA and PLS-DA analysis revealed clear discrimination among groups, in particular for AML patients. Main lipid groups differentially expressed were: Monoacylglycerols (MAG), Glucosylceramide E (GlcdE), Ethyl Esters (EE), Lysophosphatidic acid (LPA), Sulfoquinovosil diacylglycerols (SQDG), Monoglycerols (MG), Methyl Ethanolamines (ME), Lysophosphatidylcholines (LPC), Dimethyl Phosfatidyletanolamines (DMPE), Monometylphosphatidiletanolamines (MMPE), Ceramide-1-phosphate (CerP), Glicerophosphoglycerols (GP), Lysomonomethyl-Phosphatidylethanolamines (LMMPE), Phosphatidic Acids (PA), Ergosterols (ERG), Glycerophosphoserine (PS), Diacylglycerols (DAG), Hexocylceramides (HexCer) and Lanosterol (Lan). ROC Curve Analysis revealed Total LMMPE as the strongest discriminating marker between Controls from Patients. In addition, these lipids were also able to differentiate MDS and AML from NPM. Conclusions: The Myeloproliferative Neoplasms from the point of view

Abstract: Malaria is still the most destructive and dangerous parasitic infection in many tropical and subtropical countries. The burden of this disease is getting worse, mainly due to the increasing resistance of Plasmodium falciparum against the widely available antimalarial drugs. There is an urgent need for new, more affordable and accessible antimalarial agents possessing original modes of action. Natural products have played a dominant role in the discovery of leads for the development of drugs to treat human diseases, and this fact anticipates that new antimalarial leads may certainly emerge from tropical plant sources. This present review covers most of the recently-published non-alkaloidal natural compounds from plants with antiplasmodial and antimalarial properties, belonging to the classes of terpenes, limonoids, flavonoids, chromones, xanthones, anthraquinones, miscellaneous and related compounds, besides the majority of papers describing antiplasmodial crude extracts published in the last five years not reviewed before. In addition, some perspectives and remarks on the development of new drugs and phytomedicines for malaria are succinctly discussed.
