Influência da luz LED em culturas de células-tronco mesenquimais in-vitro

Stem cells are defined as cells capable of self-renewal and differentiation into specialized cells when submited to external signalings in the enviroment. Among adult stem cells, mesenchymal cells occupy an important position because they can differentiate into mesodermal cells such as osteoblasts, adipocytes and chondrocytes. Cell therapy consists in the use of mesenchymal stem cells (MSC) in the treatment of degenerative diseases and harmed tissue reconstruction. Due to the longstanding and costly procedure for cultivation of MSC, it was proposed the use of low power light sources, such as light emitting diodes (LED), to optimize these factors. Recent works have shown a series of results from the influence of LED light on biological tissues such as increased rate of cell proliferation, increased RNA, DNA and ATP synthesis rate. The purpose of this study is to compare the biomodulator effect of LED light set at wavelengths 630nm ± 10nm and 805nm ± 10nm on the mesenchymal stem cells proliferation. For this, the mesenchymal stem cells culture adopted the procedure used in the Departament of Animal Reproduction and Veterinary Radiology of the Faculty of Veterinary Medicine and Animal Sciences of Botucatu. MSC were obtained from an adult horse bone marrow, and isolated by density gradient separation, with the FICOLL reagent and by centrifugation. The pellet containing the stem cells was removed and these were placed in low glucose DMEM culture medium, containing 10% fetal calf serum and antibiotics. The material was observed daily by inverted microscopy for monitoring the progression of the cells and subsequently the amount of cells were counted in a Neubauer counting chamber. The amount of MSC was obtained by cell culture seeded in 24 wells culture plate and segregated into three distinct groups: Group 1 was irradiated with wavelength set at 630nm ± 10 nm, Group...

As duas culturas: Antonio Candido e a formação da sociologia e da literatura no Brasil

Antonio Candido, author of fundamental papers to understand Brazil’s cultures process formation, in his works about sociology and literature formation, he draws an explanation of these process of cultural genesis by mean of referential and functional systems, that become possible Brazilian society expression though scientific and literary cultures. These processes and explanations look at for functional correlations between elements and system by mean of relationship between authors-works-receptors, nevertheless, it must to investigate the individual contributions of authors and works to formation of shapes and directions of system.

Culturas e epistemologias do sul: as relações internacionais traduzidas pelos movimentos sociais da América Latina

Desde perspectivas poscoloniales, se pretende comprender el tema de la mirada latinoamericana sobre las Relaciones Internacionales, teniendo como ejes las formaciones de identidades de la "periferia" del sistema internacional, las cuales poseen reminiscencias de los procesos coloniales. Por lo tanto, iniciamos con las siguientes preguntas: "¿Cuál es el papel de la cultura en la política mundial?", "Es posible entender las Relaciones Internacionales como un campo de conocimiento sin tener en cuenta las voces silenciadas por los procesos históricos de colonización?", "¿Cuáles son las características del sistema internacional actual y cuál es la relación entre ellas y los procesos locales de subordinación en América Latina? ". En base a estas preguntas, tratamos de contextualizar la disciplina de RI como poseedora de dinámicas de poder internas, que son influenciadas por la coyuntura jerárquica y colonial del sistema internacional, configurando, así, un círculo de prácticas y fundamentos teóricos que afectan localidades fuera de los grandes centros de poder.

Comparação do custo de produção do crambe (Cambe abyssinica Hochst) com outras culturas oleaginosas em sistema de plantio direto

Biodiesel is a reality in Brazil, due to the National Program of Biodiesel Production and Use (PNPB), which became mandatory in 2008 in adding 2% biodiesel in all diesel sold in a blend known as B2. The agribusiness sector responded to the federal program, facing many difficulties in biodiesel production, which highlights the supply of raw material. Problems related to biodiesel production were mainly the shortage of vegetable oil, because of demand from domestic and foreign markets, and rising prices of raw materials available for production, making this biofuel production economically feasible, even in Brazil, where agricultural production costs are among the most competitive in the world. The crambe is a specie that has aroused the interest of Brazilian producers due to oil content, hardiness, and mechanized cultivation, mainly for being a winter crop, it becomes one more option for farmers in this period. In addition, you can compose systems of crop rotation as well as being used as ground cover in winter. The aim of this study was to evaluate the potential for productive and cost of production of crambe, conducted in no-tillage system, to compare these parameters with other oil crops such as sunflower, canola and soybean. The trial was conducted in the agricultural year 2008 at the Experimental Farm Lageado belonging to the Faculty of Agronomic Sciences - UNESP, located in Botucatu - SP. The estimated yield was 1.507,05 kg ha-1, resulting in a production of 561,94 liters of oil per hectare. The cost of installation and conduct of crambe per hectare was R$ 875,87, resulting in a cost of R$ 1,56 per liter of oil, the lowest cost among the oilseed crops analyzed.
