Distribution, biology and host specificity of Cyrtobagous singularis Hustache (Coleoptera: Curculionidae) for the biological control of Salvinia molesta
Cyrtobagous singularis Hust. was recorded from Brazil, Paraguay, Uruguay and Argentina in association with six species of Salvinia (aquatic ferns). Field observations and laboratory studies in BrazilExpand
A high percentage of BRAFV600E alleles in papillary thyroid carcinoma predicts a poorer outcome.
CONTEXT BRAF(V600E) is considered a negative prognostic marker in papillary thyroid carcinoma (PTC), but unexplained conflicting results are present in the literature. In light of the new findingExpand
The primary occurrence of BRAF(V600E) is a rare clonal event in papillary thyroid carcinoma.
CONTEXT BRAF(V600E) is considered a primary event, a negative prognostic marker, and a site for pharmacological intervention in papillary thyroid carcinoma (PTC). We asked whether BRAF(V600E) canExpand
Native distribution of the Salvinia auriculata complex and keys to species identification
Abstract The native distributions of Salvinia biloba Raddi and S. molesta D.S. Mitchell were localised, respectively, in areas north and south of the tropic of Capricorn on the east coast of Brazil.Expand
Vigorous plants suffer most from herbivores: latitude, nitrogen and biological control of the weed Salvinia molesta
The weevil, Cyrtobagous salviniae, and moth, Samea multiplicalis, were introduced into Australia for biological control of the floating weed Salvinia molesta and formed an unusually simpleExpand
Feeding by adultCyrtobagous salviniae onSalvinia molesta under different regimes of temperature and nitrogen content and the effects on plant growth
Feeding by adultCyrtobagous salviniae was not influenced by the concentration of nitrogen in the buds ofSalvinia molesta. The time spent feeding on a bud was dependent on temperature and the rate ofExpand
MicroRNAs in parathyroid physiopathology
Parathyroid glands regulate calcium homeostasis through synthesis and secretion of parathormone (PTH). They sense the extracellular calcium concentration through the G-protein coupled calcium sensingExpand
Success in Biological Control of Aquatic Weeds by Arthropods
Aquatic vascular plants have successfully colonised fresh waters in all climatic zones and although most species are rooted in the substrate, a few float freely. Most species have structuralExpand
Successful biological control of the floating weed salvinia
The floating fern Salvinia molesta D. S. Mitchell (Salviniaceae) originated in southeastern Brazil1, but since about 1930, it has been introduced into various tropical and subtropical regions whereExpand
