Astragalus sinicus (Chinese Milk vetch), a green manure leguminous plant, harbors Mesorhizobium huakuii subsp. rengei strain B3 in the root nodules. The visualization of symbiotic plasmid of strain B3 showed the presence of one sym plasmid of about 425 kbp. Curing of sym plasmid by temperature and acrydine orange was studied. Growing rhizobial cells at high temperature (37 degrees C) or treatin...

Phacelia scopulina var. submutica (Debeque phacelia) and Astragalus debequaeus (Debeque milkvetch) in Western Colorado

Astragalus membranaceus is a medicinal plant traditionally used in China for a variety of conditions, including inflammatory and neural diseases. Astragalus polysaccharides are shown to reduce the adverse effect of levodopa which is used to treat Parkinson's disease (PD). However, the neuroprotective effect of Astragalus polysaccharides per se in PD is lacking. Using Caenorhabditis elegans mode...

Astragalus, a commonly used traditional Chinese medicine, has exhibited antitumor actions in patients. In this study, in vitro and in vivo antitumor effects of astragalus and synergistic antitumor efficacy in combination with pterostilbene were investigated. Melanoma cells were treated with pterostilbene (Pt), graduated doses of astragalus injection (AI), or these in combination. Cell viability...

The oldest Giraffa material presently known consists of dental specimens. The oldest post-cranial Giraffa material belongs to the Plio-Pleistocene taxon Giraffa sivalensis, where the holotype is a third cervical vertebra. We describe three non-dental specimens from the Early Late Miocene of the Potwar Plateau, including an 8.1 million year old ossicone, 9.4 million year old astragalus, and 8.9 ...

This aim of this study was to explore the effects and molecular mechanisms of Astragalus extract against cerebral ischemia injury through the energy metabolism and apoptosis pathways of c‑Jun N-terminal kinase (JNK) signal transduction. After the bilateral common carotid artery of C57BL/6 mice was occluded for 20 min followed by 1-h reperfusion, the ATP content, total adenine nucleotides (TAN),...

The hypotheses about the origin of the primitive amniotic tarsus are very speculative. Early studies argued that the origin of the astragalus, one of the largest proximal bones in the tarsus of basal amniotes, was produced by either the fusion of two, three, or even four of the original tarsal bones, the intermedium, the tibiale and the proximal centralia (c4 and c3), or that the intermedium al...

Ernest Sosa has long defended bi-level virtue epistemology on the grounds that it offers the best overall treatment of epistemology’s central issues. A surprising number of problems “yield to” the approach (Sosa 1991: 9). Sosa applies bi-level virtue epistemology to diagnose and bypass ongoing disputes in contemporary epistemology, including the disputes between foundationalists and coherentist...
