The aim of this study was to establish reference concentrations (LC₅₀ e LC₉₀) of aqueous extracts of Bidens pilosa on the land snail Subulina octona, in order to assess the changes caused by 24 and 48 h exposure to the sublethal concentration regarding species' fecundity, hatchability and in offspring produced after exposure to confirm the presence of tannins, saponins and flavonoids in this pl...

In order to determine anti-adipogenic effect, this study investigated 1β-hydroxy-2-oxopomolic acid (HOA) isolated from Agrimonia pilosa inhibits adipocyte differentiation and expression of adipogenic marker genes, such as peroxisome proliferator activated receptor γ (PPARγ), CCAAT-enhancer-binding protein α (C/EBPα), glucose transporter 4 (GLUT4), adiponectin, adipocyte fatty acid-binding prote...

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...

The study investigated cytotoxicity of essential oils from four medicinal plants (Bidens pilosa, Ocimum gratissimum, Cymbopogon nardus, and Zanthoxylum chalybeum) on human gingival fibroblasts and their effects on proinflammatory mediators' secretion. Cytotoxicity of essential oils was investigated using 3-(4, 5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide assay. Effects of essential ...

A new tiger moth, Micrarctia kautti sp. n., from southwest China, Sichuan is described. A diagnostic comparison with Micrarctia trigona (Leech, 1899) is provided. During recent years the Chinese Arctiini have been intensively collected and explored (Dubatolov, 1996a; Dubatolov, 1996b; Dubatolov, 2003; Dubatolov, Kishida & Wu, 2005; Fang & Cao, 1984; Fang, 2000 and numerous other publications) s...
