The ASTRO-H X-ray Observatory

The joint JAXA/NASA ASTRO-H mission is the sixth in a series of highly successful X-ray missions initiated by the Institute of Space and Astronautical Science (ISAS). ASTRO-H will investigate the physics of the high-energy universe via a suite of four instruments, covering a very wide energy range, from 0.3 keV to 600 keV. These instruments include a high-resolution, high-throughput spectrometer sensitive over 0.3-2 keV with high spectral resolution of Delta E < 7 eV, enabled by a micro-calorimeter array located in the focal plane of thin-foil X-ray optics; hard X-ray imaging spectrometers covering 5-80 keV, located in the focal plane of multilayer-coated, focusing hard X-ray mirrors; a wide-field imaging spectrometer sensitive over 0.4-12 keV, with an X-ray CCD camera in the focal plane of a soft X-ray telescope; and a non-focusing Compton-camera type soft gamma-ray detector, sensitive in the 40-600 keV band. The simultaneous broad bandpass, coupled with high spectral resolution, will enable the pursuit of a wide variety of important science themes.Comment: 22 pages, 17 figures, Proceedings of the SPIE Astronomical Instrumentation "Space Telescopes and Instrumentation 2012: Ultraviolet to Gamma Ray

The Quiescent Intracluster Medium in the Core of the Perseus Cluster

Clusters of galaxies are the most massive gravitationally-bound objects in the Universe and are still forming. They are thus important probes of cosmological parameters and a host of astrophysical processes. Knowledge of the dynamics of the pervasive hot gas, which dominates in mass over stars in a cluster, is a crucial missing ingredient. It can enable new insights into mechanical energy injection by the central supermassive black hole and the use of hydrostatic equilibrium for the determination of cluster masses. X-rays from the core of the Perseus cluster are emitted by the 50 million K diffuse hot plasma filling its gravitational potential well. The Active Galactic Nucleus of the central galaxy NGC1275 is pumping jetted energy into the surrounding intracluster medium, creating buoyant bubbles filled with relativistic plasma. These likely induce motions in the intracluster medium and heat the inner gas preventing runaway radiative cooling; a process known as Active Galactic Nucleus Feedback. Here we report on Hitomi X-ray observations of the Perseus cluster core, which reveal a remarkably quiescent atmosphere where the gas has a line-of-sight velocity dispersion of 164+/-10 km/s in a region 30-60 kpc from the central nucleus. A gradient in the line-of-sight velocity of 150+/-70 km/s is found across the 60 kpc image of the cluster core. Turbulent pressure support in the gas is 4% or less of the thermodynamic pressure, with large scale shear at most doubling that estimate. We infer that total cluster masses determined from hydrostatic equilibrium in the central regions need little correction for turbulent pressure.Comment: 31 pages, 11 Figs, published in Nature July

Studies of Multiple Endocrine Neoplasia Type 2A Syndrome: Linkage Analyses and Comparison of Constitutional and Tumor Genotypes

Linkage analyses were carried out in nine Japanese kindreds with multiple endocrine neoplasia type 2A (MEN-2A) using polymorphic classical markers and DNA markers. We excluded close linkage of the MEN-2A gene (MEN2A) locus with Gm, JK, PGMl, and a DNA segment, D20S5, which is assigned to band 12 of the short arm of chromosome 20 (20p12.2). Assuming that MEN2A is recessive at the cellular level as in retinoblastoma (RB) and Wilms\u27 tumor (WT). comparison of constitutional and tumor genotypes may be useful in the search for the MEN2A locus. When DNA samples from 12 patients with medullary thyroid carcinoma (MTC) were compared with 15 polymorphic DNA markers including two assigned to chromosome 20, the results were negative. Both the negative linkage data and the failure to find loss of heterozygosity in MTC with chromosome 20 probes suggest that MEN2A may not be at 20p12.2, which was previously suggested as the site of an inherited chromosomal deletion in MEN-2A

Hyperreactivity of lymphocytes to streptolysin O and lack of plasma inhibitory factor (s) in patients with mucocutaneous lymphnode syndrome.

Lymphocyte activation by streptolysin O (SLO) and factors in the plasma which inhibit the response to SLO were examined in 19 patients with mucocutaneous lymphnode syndrome (MCLS), 54 age-matched (6 months-6 years) normal children, 41 normal children older than 6 years and 10 normal adults. In normal children younger than 6 years, the response to SLO was weak and in many cases no response was seen. On the other hand, in the patients with MCLS, the response of lymphocytes to SLO was high and comparable to the response in adults and children older than 6 years. The DNA synthesis of lymphocytes stimulated by SLO was inhibited almost completely by autologous or allogeneic plasma of many of the normal children and adults. The plasma of patients with MCLS did not inhibit, but rather enhanced the response to SLO. These results suggest that the increased response of lymphocytes to SLO and the lack of plasma inhibitory factors in patients with MCLS may be due to the immune response to the pathogen of MCLS, as yet undiscovered.</p

Cell-mediated cytotoxicity-supporting activity of various human gammaglobulin preparations.

Antibody activity, especially that involved in the reaction of antibody-dependent cell-mediated cytotoxicity (ADCC), of five commercially available human gammaglobulin preparations (standard, pepsin-treated, plasmin-treated, polyethylene glycol-fractionated and S-sulfonated gammaglobulin) was measured. All these gammaglobulin preparations had high titers of hemagglutination inhibition and neutralizing antibody against measles virus. In ADCC reaction, the pepsin-treated gammaglobulin preparation showed no antibody activity. The standard gammaglobulin preparation showed weak activity only when highly diluted. The remaining three preparations showed high activity. Though the S-sulfonated gammaglobulin preparation showed no activity in ADCC reaction, it showed high activity after reconversion by means of oxidation and reduction in vitro. The plasmin-treated gammaglobulin preparation showed greater activity than the polyethylene glycol-fractionated preparation of the optimal concentration. In ADCC tests using the plasmin-treated gammaglobulin preparation, K cell activity was strongly inhibited by Hg (thimerosal), while, in those using the standard gammaglobulin preparation, the activity was hardly influenced by Hg, suggesting that the low ADCC activity of the standard gammaglobulin preparation of high concentrations was due to the inhibitory effect of aggregated immunoglobulin G molecules.</p
