Results of the search for inspiraling compact star binaries from TAMA300's observation in 2000-2004
We analyze the data of TAMA300 detector to search for gravitational waves
from inspiraling compact star binaries with masses of the component stars in
the range 1-3Msolar. In this analysis, 2705 hours of data, taken during the
years 2000-2004, are used for the event search. We combine the results of
different observation runs, and obtained a single upper limit on the rate of
the coalescence of compact binaries in our Galaxy of 20 per year at a 90%
confidence level. In this upper limit, the effect of various systematic errors
such like the uncertainty of the background estimation and the calibration of
the detector's sensitivity are included.Comment: 8 pages, 4 Postscript figures, uses revtex4.sty The author list was

Observation results by the TAMA300 detector on gravitational wave bursts from stellar-core collapses
We present data-analysis schemes and results of observations with the TAMA300
gravitational-wave detector, targeting burst signals from stellar-core collapse
events. In analyses for burst gravitational waves, the detection and
fake-reduction schemes are different from well-investigated ones for a
chirp-wave analysis, because precise waveform templates are not available. We
used an excess-power filter for the extraction of gravitational-wave
candidates, and developed two methods for the reduction of fake events caused
by non-stationary noises of the detector. These analysis schemes were applied
to real data from the TAMA300 interferometric gravitational wave detector. As a
result, fake events were reduced by a factor of about 1000 in the best cases.
The resultant event candidates were interpreted from an astronomical viewpoint.
We set an upper limit of 2.2x10^3 events/sec on the burst gravitational-wave
event rate in our Galaxy with a confidence level of 90%. This work sets a
milestone and prospects on the search for burst gravitational waves, by
establishing an analysis scheme for the observation data from an
interferometric gravitational wave detector
Enhancement of lymphatic transport of lutein by oral administration of a solid dispersion and a self-microemulsifying drug delivery system.
Lutein is located in the macula lutea in the human eye. Since humans cannot synthesize lutein de novo, it must be digested as food. Some studies including our previous study showed very low absorption of lutein after oral administration. These studies also suggested that the absorption route of lutein from the small intestine involves not only the blood but also the lymph. The aim of this study was to clarify the transfer of lutein into lymph and the tissue distribution after oral administration of a solid dispersion (SD) and a self-microemulsifying drug delivery system (SMEDDS) for improvement of the absorption. We used thoracic lymph-cannulated rats. It was shown that the plasma concentrations of lutein in the SD and SMEDDS groups were increased compared with that in the powder group. The absorption of lutein after oral administration of each formulation was clearly evaluated by its cumulative amount in lymph. Our data clearly showed that lutein is transferred into the lymph stream from the small intestine
Clear cell papillary cystadenocarcinoma of the epididymis: a case report and immunohistochemistry of markers for renal cell carcinoma
Neoplasms of the epididymis are uncommon,
and malignant tumors are extremely rare. We report a
case of clear cell papillary cystadenocarcinoma of the
epididymis presenting with a long history of painless
scrotal mass on the left side. Immunohistochemical
markers for clear cell renal cell carcinoma (RCC) were
examined to distinguish between clear cell papillary
cystadenocarcinoma of the epididymis and metastatic
clear cell renal cell carcinoma. The present case was
positive for cytokeratin-7, PAX2, vinculin, vimentin and
carbonic anhydrase IX. Expression of CD10 was focally
observed. In contrast, no immunoreactivities for α-
methylacyl-CoA racemase, RCC marker, glutathione Stransferase
α or C-KIT were detected. The immunophenotypic
profile of clear cell papillary cystadenocarcinoma
of the epididymis closely resembles that of
clear cell papillary RCC, although the immunohistochemical
markers tested in this study are useful to make
a differential diagnosis between clear cell papillary
cystadenocarcinoma of the epididymis and metastatic
clear cell RCC
