We are using the NRAO Very Long Baseline Array (VLBA) and the Japanese VERA project to measure trigonometric parallaxes and proper motions of masers found in high-mass star-forming regions across the Milky Way. Early results from 18 sources locate several spiral arms. The Perseus spiral arm has a pitch angle of 16 • ±3 • , which favors four rather than two(More)
ADAMTS13 biosynthesis appeared to occur mainly in hepatic stellate cells, but detection of ADAMTS13 mRNA in many other tissues suggests that vascular en-dothelium may also produce ADAMTS13. We showed that ADAMTS13 mRNA and protein were detectable in human umbilical vein endothelial cells, aortic endothe-lial cells, and endothelium-derived cell line(More)
We report trigonometric parallaxes for the sources NGC 7538 and Cep A, corresponding to distances of 2.65 −0.04 kpc, respectively. The distance to NGC 7538 is considerably smaller than its kinematic distance and places it in the Perseus spiral arm. The distance to Cep A is also smaller than its kinematic distance and places it in the " Local " arm or spur.(More)
We have used the Very Large Array to search for compact milliarcsecond-size radio sources near methanol masers in high-mass star-forming regions. Such sources are required for Very Long Baseline Interferometry phase-referencing observations. We conducted pointed observations of 234 compact sources found in the NVSS survey and find 92 sources with unresolved(More)
We report trigonometric parallaxes for G59.7+0.1 and W 51 IRS2, corresponding to distances of 2.16 −1.4 kpc, respectively. The distance to G59.7+0.1 is smaller than its near kinematic distance and places it between the Carina-Sagittarius and Perseus spiral arms, probably in the Local (Orion) spur. The distance to W 51 IRS2, while subject to significant(More)
in the rest of the disk. The correlation remains notable even if we do not apply a thickness filter to the data or if we use another definition of the thickness (3, 11). The two maps are not independent, however; changing the density distribution in the arms will necessarily produce changes in the measured thickness unless the perturbations are distributed(More)
To detect Salmonella more efficiently and isolate strains more easily, a novel and simple detection method that uses an enrichment assay and two chromogenic reactions on a chromatography membrane was developed. Grade 3 chromatography paper is used as functionalized solid phase support (SPS), which contains specially optimized medium. One reaction for(More)
We report trigonometric parallaxes for the massive star-forming regions G23.01–0.41 and G23.44–0.18, corresponding to distances of 4.59 −0.93 kpc, respectively. The distance to G23.01–0.41 is smaller than its near kinematic distance assuming a standard model of the Milky Way and less than half of its far kinematic distance, which has usually been assumed.(More)
The ancient silk road of China passed through Xinjiang and facilitated gene exchanges from the East and the West which impacted on the genetic variation and structure of the nomadic Kazakh population residing there. In order to understand the nature of this genetic variation, 151 Xinjiang Kazakh samples were obtained from four main Kazakh groups and were(More)
