The evolution of armadillos, anteaters and sloths depicted by nuclear and mitochondrial phylogenies: implications for the status of the enigmatic fossil Eurotamandua.
The mammalian order Xenarthra (armadillos, anteaters and sloths) is one of the four major clades of placentals, but it remains poorly studied from the molecular phylogenetics perspective. We present here a study encompassing most of the order's diversity in order to establish xenarthrans' intra-ordinal relationships, discuss the evolution of their morphological characters, search for their exta...
متن کاملBradypus variegatus (Pilosa: Bradypodidae)
Bradypus variegatus Schinz, 1825 (the brown-throated three-toed sloth), is 1 of 4 extant three-toed sloths. A highcanopy folivore, B. variegatus is distributed over southern Central America and northern and central South America and is listed as Least Concern by the International Union for Conservation of Nature and Natural Resources because of its wide distribution. Males have a middorsal spec...

Background and objectives: Argyreia pilosa (Convolvulaceae) has been utilized for many aliments in the conventional system ethnomedicinally; most significantly against sexually transmitted diseases, skin troubles, diabetes, rheumatism, cough, and quinsy. The key challenge experienced in the standardization of herbal drugs is the correct identification of the plant sour...
متن کاملAcetylcholinesterase inhibition by flavonoids from Agrimonia pilosa.
In a bioassay-guided search for acetylcholinesterase (AChE) inhibitors from 180 medicinal plants, an ethyl acetate extract of whole plants of Agrimonia pilosa ledeb yielded tiliroside (1), 3-methoxy quercetin (2), quercitrin (3) and quercetin (4). We report herein for the first time that all four flavonol compounds showed significant inhibitory effects on AChE, particularly quercetin (4), which...
متن کاملCytopiloyne, a novel polyacetylenic glucoside from Bidens pilosa, functions as a T helper cell modulator.
An extract of Bidens pilosa, an anti-diabetic Asteraceae plant, has recently been reported to modulate T cell differentiation and prevent the development of non-obese diabetes (NOD) in NOD mice. In this paper, a novel bioactive polyacetylenic glucoside, cytopiloyne (1), was identified from the Bidens pilosa extract using ex vivo T cell differentiation assays based on a bioactivity-guided fracti...
