Proposta de Sistema de Monitoramento da Sigatoka-Negra Baseado em Variáveis Ambientais Utilizando o TerraMA2
Banana crops have been affected by a disease known as black sigatoka. There are still few studies that consider the spatial distribution and dynamics involved in the dispersion process, as well as monitoring systems that incorporate such information. In this context, the geospatial tools are promising, especially when integrated to geographic information systems with the capacity to incorporate...
متن کاملAnti-adult T-cell leukemia effects of Bidens pilosa.
We evaluated the effects of Bidens pilosa, a plant found in tropical and subtropical regions, and investigated the molecular pathways responsible for the anti-adult T-cell leukemia (ATL) effect. Water extracts of B. pilosa had growth suppressive effects on human T-cell leukemia virus type 1 (HTLV-1)-infected T-cell lines and ATL cells. B. pilosa extracts arrested cells in G1 cell cycle and indu...
متن کاملFlavonoids, centaurein and centaureidin, from Bidens pilosa, stimulate IFN- expression
Bidens pilosa is used as an ethnical medicine for bacterial infection or immune modulation in Asia, America and Africa. Here, we employed n IFNpromoter-driven luciferase reporter construct and T cells to characterize immunomodulatory compounds from this plant based on a ioactivity-guided isolation principle. We found that PHA, a positive control, caused a six-fold increase in IFNpromoter activi...
متن کاملRetenção do fungicida triadimenol em latossolos em razão da calagem e da fosfatagem
The objective of this work was to evaluate the effect of liming and phosphate applications on the retention of triadimenol in microcolumns of soil material of a distrophic Red-Yellow Latosol (Typic Hapludox) and a distrophic Red Latosol (Typic Hapludox). Lime and phosphate applications decreased retention of triadimenol on LVAd samples (7.7% and 8.6%, respectively, for 2.67 and 10.68 kg ha-1 of...
متن کاملCompilation of secondary metabolites from Bidens pilosa L.
Bidens pilosa L. is a cosmopolitan annual herb, known for its traditional use in treating various diseases and thus much studied for the biological activity of its extracts, fractions and isolated compounds. Polyacetylenes and flavonoids, typical metabolite classes in the Bidens genus, predominate in the phytochemistry of B. pilosa. These classes of compounds have great taxonomic significance. ...
