Conteúdo:  Abstract Despite the progress on development of new culture media, in vitro-produced embryos still display lower quality when compared to the in vivo-produced counterparts. Coculture has been reconsidered as an alternative to improve embryo quality. Mesenchymal stem cells (MSC) and murine embryonic fibroblasts (MEF) have been extensively used as feeder layers due to their capacity to release growth factors. In the present study we investigated the effect of these feeder layers in oocyte maturation and/or embryo development under in vitro conditions. Oocytes were matured in control (CTRL) conditions or in coculture with MSC or MEF. In vitro fertilization and embryo culture until fourth day were performed in CTRL condition for all groups. Embryos from fourth day on were then cultured until the eighth day in CTRL or in coculture system. No significant differences for metaphase II stage and apoptosis in oocytes were found among the groups. There was also no difference among the groups when we evaluated blastocyst formation on the seventh and eighth day, with exception of a higher hatched blastocyst rate in the group maturated and cultivated in CTRL condition when compared to the group matured and cocultured with MSC. Also no difference was observed in the number of cells in the whole embryos, in the inner cell mass, in the trophoblast and at apoptotic stage on the eighth day. We conclude that coculture with MSC or MEF during maturation and/or embryo development do not enhance th... Mostrar Tudo

Título:  Temperature sensitivity of soil organic matter decomposition varies with biocharapplication and soil type.

Conteúdo:  Biochar application has the potential to improve soil fertility and increase soil carbon stock, especially in tropical regions. Information on the temperaturesensitivity of carbon dioxide (CO2) evolution from biochar-amended soils at very high temperatures, as observed for tropical surface soils, is limited buturgently needed for the development of region-specific biochar management targeted to optimize biochar effects on soil functions. Here, we investigated thetemperature sensitivity of soil respiration to the addition of different rates ofMiscanthusbiochar (0, 6.25, 12.5, and 25 Mg ha−1) in two types of soils withcontrasting textures. Biochar-amended soil treatments and their controls were incubated at constant temperatures of 20, 30, and 40◦C. Overall, our resultsshow that: i) considering data from all treatments and temperatures, the addition of biochar decreased soil CO2emissions when compared to untreated soils;ii) CO2emissions from biochar-amended soils had a higher temperature sensitivity than those from biochar-free soils; iii) the temperature sensitivity of soilrespiration in sandy soils was higher than that in clay soils; and iv) for clay soils, relative increases in soil CO2emissions from biochar-amended soils werehigher when the temperature increased from 30 to 40◦C, while for sandy soils, the highest temperature responses of soil respiration were observed whenincreasing the temperature from 20 to 30◦C. Together, these findings suggest a... Mostrar Tudo
