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 million year old metatarsal and refer them to Giraffa. The described ossicone exhibits remarkable similarities with the ossicones of a juvenile modern giraffe, including the distribution of secondary bone growth, posterior curvature, and concave pitted undersurface where the ossicone would attach to the skull...

The excessive activation of microglia in many neurodegenerative diseases is detrimental to neuronal survival. Isoastragaloside I (ISO I) is a natural saponin molecule found within the roots of Astragalus membranaceus, a famous traditional Chinese medicine. In the present study, the anti‑inflammatory effects and the mechanisms of action of ISO I on activated BV-2 cells stimulated with lipopolysaccharide (LPS) were investigated. ISO I dose‑dependently inhibited the excessive release of nitric oxide (NO) and tumor necrosis factor (TNF)-α in the LPS-stimulated BV-2 cells...

In this work, the changes in isoflavone levels and the expression of genes involved in their biosynthesis were studied in two Astragalus by UPLC-MS and real-time PCR after 10 days of UV-B treatment (λmax = 313 nm, 804 J/ m(2) ). Isoflavones were significantly induced by UV-B irradiation. The influence might be activated by the regulation of these target genes. Our results indicate that (1) the resistance of A. membranaceus might not be as good as A. mongholicus in the enhanced UV-B radiation environment; (2) the enhanced accumulation of Calycosin and Calycosin-7-glucoside with UV-B treatment in roots of A...

BACKGROUND: Astragalus was broadly used for treating heart failure (HF) and arrhythmias in East Asia for thousands of years. Astragalus granule (AG), extracted from Astragalus, shows beneficial effect on the treatment of HF in clinical research. We hypothesized that administration of AG prevents the remodeling of L-type Ca(2+) current (ICa-L) in HF mice by the downregulation of Ca(2+)/calmodulin-dependent protein kinase II (CaMKII). METHODS: HF mice were induced by thoracic aortic constriction (TAC)...

Astragalus membranaceus (Fisch) Bge(Huang-Qi) is a well-known herbal medicine with tonic property and has been widely used to treat cancer and other immune disorders in China and Southeast Asia for thousands of years. Accumulating evidence suggests that Huang-Qi possesses both immune-boosting and anti-inflammatory/immune-regulatory effects clinically, leaving the mechanism elusive. Recently, we discovered that Astragaloside (ASI), a major active component of Huang-Qi, is able to increase CD45 phosphatase activity...
