Alzheimer's disease (AD) is a neurodegenerative brain disorder and the most common cause of dementia. New treatments for AD are required due to its increasing prevalence in aging populations. The present study evaluated the effects of the active components of Epimedium, Astragalus and Radix Puerariae on learning and memory impairment, β-amyloid (Aβ) reduction and brain iron load in an APPswe/PS...

gum tragacanth is a natural complex mixture of polysaccharides and alkaline minerals extracted from species of astragalus plant, which is found widely in arid regions of the middle east. in a pilot experimental study we examined the effects of its topical application on wound healing in ten albino adult male rats. two similar parasagittal elliptical full-thickness wounds (control vs. test sampl...

The present study proposes the restructuring of Ologamasiphis genus (family Parasitidae) comprising two subgenera s. and Holzmannia Juvara-Balş, 2002, to have respective elevated level, as well brand-new Juvaria subgenus created within genus. proposed is based on newly described species belonging n. subgen., wit (Juvaria) pilosa sp. silvestris Furthermore, new are described: setosus zelkovae Pe...

The Patagonian steppe is an immense, cold, arid region, yet phylogeographically understudied. Nassauvia subgen. Strongyloma is a characteristic element of the steppe, exhibiting a continuum of morphological variation. This taxon provides a relevant phylogeographical model not only to understand how past environmental changes shaped the genetic structure of its populations, but also to explore p...

Astragalus, as the largest genus of flowering plants, is well-known for its high species richness and morphological diversity. Previous studies suggested that many subgenera Astragalus are not monophyletic phylogenetic relationships within still poorly known. In this study, we sampled 117 accessions close relatives, covering 55 sections plus 30 outgroup taxa to recover main clades eastern Asian...
