Propriedades quĂmicas de uma Terra Roxa Estruturada influenciadas pela cobertura vegetal de inverno e pela adubação orgĂąnica e mineral
O presente trabalho teve por objetivo avaliar a influĂȘncia da cobertura vegetal de inverno, constituĂda de uma associação de aveia preta (Avena strigosa Schreb) com nabo forrageiro (Raphanus sativus L.), da adubação orgĂąnica com esterco de aves e da adubação mineral sobre propriedades quĂmicas de uma Terra Roxa Estruturada do estado de Santa Catarina. As anĂĄlises foram realizadas em amostras de solo coletadas em agosto de 1994 e janeiro de 1995, nas profundidades de 0-10, 10-20 e 20-30 cm, em um experimento iniciado em 1990. Observou-se que a cobertura vegetal de inverno mostrou-se eficiente na manutenção de nutrientes, especialmente o potĂĄssio, e dos nĂveis de carbono orgĂąnico, dentro dos limites da camada arĂĄvel. O uso de adubo orgĂąnico proporcionou acĂșmulo de nutrientes no solo, enquanto os adubos organomineral e mineral mostraram tendĂȘncia de redução, principalmente dos nĂveis de potĂĄssio do solo

Supplementary Material for: A Novel ex vivo Mouse Mesometrium Culture Model for Investigating Angiogenesis in Microvascular Networks
<b><i>Background:</i></b> The development of models that incorporate intact microvascular networks enables the investigation of multicellular dynamics during angiogenesis. Our laboratory introduced the rat mesentery culture model as such a tool, which would be enhanced with mouse tissue. Since mouse mesentery is avascular, an alternative is mouse mesometrium, the connective tissue of uterine horns. The studyâs objective was to demonstrate that mouse mesometrium contains microvascular networks that can be cultured to investigate multicellular dynamics during angiogenesis. <b><i>Methods:</i></b> Harvested mesometrium tissues from C57Bl/6 female mice were cultured in media with serum for up to 7 days. PECAM, NG2, αSMA, and LYVE-1 labeling identified endothelial cells, pericytes, smooth muscle cells, and lymphatic endothelial cells, respectively.<b><i> Results:</i></b> These cells comprised microvascular networks with arterioles, venules, and capillaries. Compared to day 0, capillary sprouts per vascular length were increased by 3 and 5 days in culture (day 0, 0.08 ± 0.01; day 3, 3.19 ± 0.78; day 5, 2.49 ± 0.05 sprouts/mm; <i>p</i> < 0.05). Time-lapse imaging of cultured tissues from FlkEGFP mice showcases the use of the model for lineage studies. The impact is supported by the identification of endothelial cell jumping from one sprout to another. <b><i>Conclusion:</i></b> These results introduce a novel culture model for investigating multicellular dynamics during angiogenesis in real-time ex vivo microvascular networks
