We have performed Ce M4,5-edge X-ray absorption (XAS) and Ce 3d-4f resonance photoemission (RPES) spectroscopies on quasicrystal approximant Au59.2Ga25.7Ce15.1. The 3d94f1 final state originating from the itinerant 4f electronic states is negligible in the Ce M4,5-edge XAS. The Ce 3d-4f RPES spectrum shows the relatively large the spectral weight of the 4f0 final state to that of the 4f1 final state, reflecting the weak hybridization between the localized 4f orbitals and the conduction bands. The localized 4f electronic states in Au59.2Ga25.7Ce15.1 are revealed by both spectroscopies.

Red ginger (Zingiber officinale var. Rubra) has been prescribed as an analgesic for arthritis pain in Indonesian traditional medicine. The surface color of the rhizome is purple because of the anthocyanidins in its peel. We prepared 40% ethanolic extract from dried red ginger (red ginger extract [RGE]) and evaluated its anti-inflammatory activity using acute and chronic inflammation models. In an acetic acid-induced mouse writhing model, RGE (10–100mg/kg) suppressed both the frequency of writhing and the increase in permeability of abdominal capillaries. On the other hand, continuous treatment with RGE (10mg/kg) significantly (P<.05) suppressed footpad edema in a rat adjuvant arthritis model. To clarify the anti-inflammatory mechanism of RGE, we examined the effect on prostaglandin (PG) and nitric oxide (NO) production from mouse leukemic monocytes (RAW264 cells) stimulated by lipopolysaccharide. RGE (3 and 10μg/mL) significantly (P<.05) suppressed PGE2 production, while it also suppressed NO production at 100μg/mL. After bioassay-guided separation of RGE, we found that [6]-shogaol and gingerdiols suppressed NO production. Red dye fractions presumed to be proanthocyanidins also suppressed NO production at 100μg/mL. Consequently, we found a potent suppressive effect of RGE on acute and chronic inflammation, and inhibition of macrophage activation seems to be involved in this anti-inflammatory effect. [6]-Shogaol, gingerdiols, and proanthocyanidins were identified as constituents that inhibited NO production.
