Desenvolvimento e estabilidade de formulações semi-solidas contendo extratos de soja (Glycine max (L) Merr.)

Alguns vegetais, como a soja (Glycine max L. Merr), despertam interesse, pois fornecem, entre outras substâncias, as isoflavonas, que apresentam importantes propriedades estrogênicas e, também, atuam como antioxidantes, antifúngicos e anticancerígenos. A menopausa, causada pela deficiência hormonal, é acompanhada de vários transtornos metabólicos, como perda de massa óssea, fenômenos vasomotores, dislipidemia, resistência insulínica, ganho de peso, depressão e aceleração do envelhecimento cutâneo. A terapia de reposição hormonal (TRH) é eficaz, embora possa causar efeitos secundários, como câncer de mama. Nestes casos, a fitoterapia com fitormônios por via cutânea é uma alternativa importante. Dentre as preparações de uso tópico, sistemas emulsionados e géis são muito utilizados, pois favorecem a solubilidade e a estabilidade de fármacos. Para avaliar a estabilidade das formulações, foram consideradas as características organolépticas (aspecto, cor, odor) e as características físico-químicas (valor de pH, viscosidade e densidade, etc.), separação de fases e/ou coalescência. Algumas formulações apresentam-se com características desejáveis e adequadas para a veiculação de isoflavonas presentes em extrato de soja, podendo-se sugeri-las como sistemas adequados e estáveis para sua veiculação pela via dérmica

Abordagem multivariada na análise de diversidade genética em cruzamentos para alto teor de óleo em soja

The soybean crop is considered a high expression around the world. In plant breeding programs, knowledge of genetic diversity is extremely important and in this context, are frequently used multivariate analyzes. Thus, the aim of the present study was to evaluate the genetic divergence between soybean crosses through multivariate techniques. In total, 16 crosses were evaluated, which were in the F2 generation of inbreeding. The evaluated characteristics were plant height at maturity, height of the first pod, number of branches per plant, number of pods per plant, number of nodes per plant, hundred seed weight, grain yield and oil content. For the analyzes was used Euclidean distance, methods of hierarchical clustering UPGMA and Ward and principal component analysis. Genetic distances estimated using Euclidean distance ranged from 1.24 to 8.13, with the smallest distance observed between crosses C1 and C4, and the greatest distance between the C2 crosses and C6. The methods UPGMA clustering and Ward met crossings in five different groups. The principal component analysis explained 86.2% of the variance contained in the original eight variables with three main components. The APM characters, NV, NR, NN, PG% and oil were the main contributors to genetic divergence among traits. Multivariate techniques were crucial to the analysis of genetic diversity, and the methods of Ward and UPGMA clustering and principal components have consistent results in this way, the simultaneous use of these tools in genetic analysis of crosses is indicated

Monitoramento espacial e análise das características climáticas na influência sobre a cultura de soja no estado do Paraná

In the past years, soya has increased itself as the mean agro export culture in Brazil, encouraging the expansion of its agricultural frontier throughout the country. Brazil is the second biggest soya producer around the world, with a 59,8 million ton production in 2008, according to the Instituto Brasileiro de Geografia e Estatística (IBGE), only behind United States. Around the country, the four leading producer states are Mato Grosso, Paraná, Rio Grande do Sul e Goiás. Therefore, geotechnologies may be used to monitor use and soil occupation in various analyzes periods. In this review, the tools are important to illustrate the soya production areas and also the weather behavior around its production evolution in the territory through the years. Its utilization can contribute to the evolution and optimization around real time monitoring of the Agricola cultures, without being necessary to be in the area with a low financial cost. Generally, this information is strongly important for decision makers in both government and private sector, as soon as the achievement information regards the quantification of area, yield and development of agricultural crops are essential to the economic behavior of culture during the season and even beyond. By obtaining data regarding climate crops 2008/09 and 2009/10, held the climatic water balance calculation based on the dynamics of water storage in soil temperature and precipitation data, interpolation of the data through the interpolator (IDW) that generated thematic precipitation maps. Overall, the use of geotechnology to monitor agricultural areas, can strongly contribute to this monitoring, generating raw material for further analysis at low cost

Determinação da temperatura para inativação da urease em amostras de casca e farelo de soja

s not degraded in the rumen but destroy ureasis. Soybean meal is one of the protein ingredients commonly used in formulations of animal feeds. In the diets of monogastric bran has high protein content provided by a greater separation of soybean hulls. For the ruminant protein value of the meal is lower with the inclusion of soybean hulls to reduce the level of protein. With the increased consumption of meal high protein, due to increases in production of pigs and poultry in recent years, increasing the availability of soybean hulls on the market, this is because soybean hulls is little understood in the feeding of monogastric . In this context, the main objective of this study was to determine the times and temperatures needed to ensure the effective inactivation of ureasis present in the bran and soybean hulls. According to the assessments, to make the determination of temperatures and times required for the inactivation of ureasis present in the bran and soybean hulls are 170 º C and 25 minutes for soybean meal and 140 ° C 10 minutes for soybean hulls, respectively

Medidas de adequação dos impactos causados por uma indústria de esmagamento de soja

In the last years, environmental issues are being gradually addressed because of awareness regarding the limitation of natural resources for the maintenance of life on Earth, and the role played by the media in reporting on various issues that are related to the theme. In the industrial sector, this topic becomes ever more present in its planning. With the increase of production activities, the generation of waste causes many complications, both in industry and in the environment. For this reason laws and rules were created so that such problems are minimized, thus causing less impact on the environment. In this work was a study of the possible environmental impacts in a soybean crushing industry, situated in the city of Osvaldo Cruz, São Paulo state, detailing the sources and impacts of waste generation, and associate them relevant laws. From this, measures were proposed measures of adequacy involving compliance with commitments to environmental agencies, relevant requests of buyers and / or suppliers and improving environmental performance
