| Tissue damage due to oxidative stress is directly linked to development of many, if not all, human morbidity factors and chronic diseases. In this context, the search for dietary natural occurring molecules with antioxidant activity, such as flavonoids, has become essential. In this study, we investigated a set of 41 flavonoids (23 flavones and 18 flavonols) analyzing their structures and biological antioxidant activity. The experimental data were submitted to a QSAR (quantitative structure-activity relationships) study. NMR 13C data were used to perform a Kohonen self-organizing map study, analyzing the weight that each carbon has in the activity. Additionally, we performed MLR (multilinear regression) using GA (genetic algorithms) and molecular... |

| Delaware Water Gap National Recreation Area (“the park”) covers 28,000 ha along the Delaware River in Pennsylvania and New Jersey. Eastern hemlock forests cover 2,200 ha (8%) of the park, and are often associated with trout streams and scenic waterfalls. Activities like trout fishing, bird watching, and hiking are concentrated in hemlock forests, and many of these areas are officially designated as “Outstanding Natural Features” having “high intrinsic or unique values.” In 1989 hemlock woolly adelgid (HWA) was detected in the park, and since 1993 the park has conducted a program to address the threats that hemlock woolly adelgid and hemlock decline poses to park resources. This program... |

| A mangaba, fruto nativo altamente perecível, apresenta reduzida vida útil pós-colheita. Novas tecnologias de conservação de frutos têm sido desenvolvidas, e o uso de reguladores vegetais tem sido promissor. Este trabalho avaliou a aplicação do regulador de etileno1-MCP em diferentes concentrações (250; 500 e 1.000 ηL L-1), com o objetivo de verificar o prolongamento da vida útil dos frutos e suas características físicas e químicas durante o armazenamento em temperatura ambiente e a 11ºC. O uso 1-MCP, independentemente das três concentrações utilizadas, apresenta grande benefício na conservação pós-colheita dos frutos em condição ambiente, aumentando o período de vida útil da mangaba, assim como o uso de armazenamento a 11ºC, os quais favoreceram a redução... |

| Este trabalho teve como objetivo verificar o efeito da aplicação de 1-metilciclopropeno (1-MCP) e do salicilato de metila (MeSA) no controle de injúrias pelo frio em nêsperas 'Fukuhara'. Quatro concentrações de 1-MCP foram aplicadas (0, 50, 500 e 5000nL L-1), além do MeSA (0,01mM), associado ou não ao 1-MCP 500nL L-1. Após os tratamentos os frutos foram armazenados a 1°C durante 60 dias. As determinações realizadas foram: firmeza de polpa, índice de escurecimento e podridão, acidez titulável, pH, teor de sólidos solúveis, teor de ácido ascórbico e atividade da enzima polifenoloxidase (PPO). Após 60 dias de armazenamento refrigerado, não foi observado desenvolvimento de escurecimento interno nos frutos tratados com 1-MCP e MeSA. Os frutos controle... |

| The INCF Secretariat organized a workshop to focus on the “role of neuroinformatics in the processes of building, evaluating, and using genetic animal models for brain diseases” in Stockholm, December 13–14, 2009. Eight scientists specialized in the fields of neuroinformatics, database, ontologies, and brain disease participated together with two representatives of the National Institutes of Health and the European Union, as well as three observers of the national INCF nodes of Norway, Poland, and the United Kingdom. |

| Average net farm income was $322,165 in 2010 for the 97 farms included in this annual report of the Southwestern Minnesota Farm Business Management Association. Average earnings increased by 362% from $69,787 in 2009 (Figure 1). Inflations adjusted profits rebounded after a downturn in 2009 that was caused primarily by low profits in the livestock sectors. Strong yields, substantially higher crop inventory values, and rebounding profitability of the livestock sectors led the way to much higher profits in 2010. Highlights of association financial results for 2010: Entire report is available at: http://www.cffm.umn.edu/Publications/Pubs/FBMA/SW_MN_FBMA_2010.pdf• Median net farm income, or the income earned by the middle farm, was $234,879,... |

| This report summarizes the 2010 financial and production records of 99 Michigan cash grain farms. To be included, the farms must have produced at least 50 percent of gross cash farm income from one or a combination of these items: corn, soybeans, wheat, navy beans, oats, sugar beets and other small grains. The records came from Michigan State University’s TelFarm project and Farm Credit Service of Michigan. The values were pooled into averages for reporting purposes. Farm records were included if a farm financial analysis had completed 2010 data including beginning and ending balance sheets and a statement of income and expenses. The data was checked to verify that cash discrepancy was less than 10% of gross cash inflow and that debt discrepancy was less... |
