Astrometry of Galactic Star-Forming Region Sharpless 269 with VERA : Parallax Measurements and Constraint on Outer Rotation Curve
We have performed high-precision astrometry of H2O maser sources in the Galactic star-forming region Sharpless 269 (S269) with VERA. We successfully detected a trigonometric parallax of 189 ˙ 8� as,Expand

Distance to Orion KL Measured with VERA
We present the initial results of multiepoch VLBI observations of 22 GHz H2O masers in the Orion KL region with VERA (VLBI Exploration of Radio Astrometry). With the VERA dual-beam receiving system,Expand

Astrometry of H$_2$O Masers in Nearby Star-Forming Regions with VERA I. IRAS 16293$-$2422 in $\rho$ Oph East
We report on results of multi-epoch VLBI observations of H2O masers associated with a low-mass young stellar object, IRAS 16293 2422 in Oph East, and a fringe-phase and position reference source,Expand

Carotenoids and their metabolism in the goldfish Carassius auratus (Hibuna)
A total of 18 known carotenoids and three new carotenoids, (3S, 4R, 3′S, 6′R)-4-hydroxylutein, (3S, 3′S, 4′R)-4-keto-4′-hydroxydiatoxanthin, and (3S, 3′S, 4′R)-4-keto-4′-hydroxyalloxanthin wereExpand

Anti‐neoplastic effect of halocynthiaxanthin, a metabolite of fucoxanthin
We have reported that fucoxanthin, a natural carotenoid, inhibited the growth of human neuroblastoma GOTO cells. In the present study, we show that a metabolite of fucoxanthin, halocynthiaxanthin,Expand

Comparative biochemical studies of carotenoids in sea-urchins—I
Abstract 1. 1. The carotenoids of both regular sea-urchins and irregular sea-urchins were investigated from the comparative biochemical points of view. 2. 2. Twenty-five carotenoids were obtained notExpand

Effect of β, β-carotene, β-echinenone, astaxanthin, fucoxanthin, vitamin A and vitamin e on the biological defense of the sea urchin Pseudocentrotus depressus
A disease characterized by spine loss was frequently observed among sea urchins fed a carotenoid-free diet during a feeding experiment. Furthermore, the gonads of most of them were underdeveloped. WeExpand

Carotenoids in sea urchins
Carotenoids are a source of vitamin A and natural colorants of food and feed. Many marine animals are colored. Much of the coloration is because of the presence of carotenoid as well as melanin,Expand
