Castleman's Disease of the Chest Wall
AbstractPrimary Castleman's disease of the chest wall is unusual. Furthermore, such tumors arising from a surgical wound are extremely rare. We report a 33-year-old female with a history of a thoracic surgery at 5 years of age. A round, homogenous 4 × 3.5-cm mass protruded into the thoracic cavity on the posterior portion of the previous posterolateral incision. The tumor was completely removed, with combined rib resection. The resected specimen showed Angiofollicular Lymph Node Hyperplasia (Castleman's disease), hyaline-vascular type. No recurrence has been found for 10 years. This is the first report of primary chest wall Castleman's disease arising from the surgical wound
Comparison of sulfur isotope ratio measurements by various techniques, and the δ(34)S values of some sulur standards
Three techniques (combustion of Ag(2)S by Cu(2)O, thermal decomposition of BaSO(4) and KIBA reagent method under vacuum) for sulfur isotope ratio measurements of geological samples are described in detail. The δ(34)S values of three working standards (MSS-2, MSS-3 and MSS-4) obtained by these techniques for the last 13 years were compared (Table 1 and Fig. 3): the most acceptable values of the three standards are +21.5, +3.5 and +4.5‰, respectively
Slow and Fast Transitions in the Rising Phase of Outbursts from NS-LMXB transients, AqlX-1 and 4U1608-52
We analyzed the initial rising behaviors of X-ray outbursts from two
transient low-mass X-ray binaries (LMXBs) containing a neutron-star (NS), Aql
X-1 and 4U 1608-52, which are continuously being monitored by MAXI/GSC in 2--20
keV, RXTE/ASM in 2--10 keV, and Swift/BAT in 15--50 keV. We found that the
observed ten outbursts are classified into two types by the patterns of the
relative intensity evolutions in the two energy bands below/above 15 keV. One
type behaves as the 15--50 keV intensity achieves the maximum during the
initial hard-state period and drops greatly at the hard-to-soft state
transition. On the other hand, the other type does as both the 2--15 keV and
the 15--50 keV intensities achieve the maximums after the transition. The
former have the longer initial hard-state ( 9 d) than the latter's
(\ltsim5 d). Therefore, we named them as slow-type (S-type) and fast-type
(F-type), respectively. These two types also show the differences in the
luminosity at the hard-to-soft state transition as well as in the average
luminosity before the outburst started, where the S-type are higher than the
F-type in the both. These results suggest that the X-ray radiation during the
pre-outburst period, which heats up the accretion disk and delays the disk
transition (i.e., from a geometrically thick disk to a thin one), would
determine whether the following outburst becomes S-type or F-type. The
luminosity when the hard-to-soft state transition occurs is higher than erg s in the S-type, which corresponds to 4% of the
Eddington luminosity for a 1.4 \Mo NS.Comment: 14 pages, 10 figures; Publications of the Astronomical Society of
