Effect of Long-term Feeding of Shiitake on Age-related Changes in Serum Lipids in Male SD Rats

The purpose of the present study was to observe the changes in serum lipids of rats fed a shiitake-containing diet throughout life. The serum triglyceride level of the shiitake diet group tended to be lower than that for the control diet group, but the difference was not significant. The serum phospholipid level was significantly lower in the shiitake diet group than in the control diet group (p<0.001) from 4 weeks to 36 weeks. Serum total cholesterol levels were significantly low in the shiitake diet group compared to the control diet group from 4 weeks to 36 weeks. However, the difference gradually disappeared over more than 48 weeks. Our findings suggested that reducing the serum cholesterol level and the phospholipid level beyond 36 weeks after starting a shiitake-containing diet influenced the average life span and the medium survival rate

Effects of Intravenously Injected Eritadenine on Serum Lipids in Ovariectomized (OVX) Rats

This research investigated and reported on whether or not intravenous administration of eritadenine to ovariectomized (OVX) rats affects serum lipid parameters like those found in the results of studies on its oral administration. Serum triglyceride, phospholipid, and total cholesterol levels were significantly lower in the OVX and Sham groups intravenously administered eritadenine than in the control OVX and Sham groups. The present results suggest that the administration of eritadenine in saline at a rate of 0.5 mg/mL and amount of 1 mL per kg of body weight via the tail vein for 10 days decreased serum lipid levels to a similar extent as when it was orally administered

Coincidence analysis to search for inspiraling compact binaries using TAMA300 and LISM data

Japanese laser interferometric gravitational wave detectors, TAMA300 and LISM, performed a coincident observation during 2001. We perform a coincidence analysis to search for inspiraling compact binaries. The length of data used for the coincidence analysis is 275 hours when both TAMA300 and LISM detectors are operated simultaneously. TAMA300 and LISM data are analyzed by matched filtering, and candidates for gravitational wave events are obtained. If there is a true gravitational wave signal, it should appear in both data of detectors with consistent waveforms characterized by masses of stars, amplitude of the signal, the coalescence time and so on. We introduce a set of coincidence conditions of the parameters, and search for coincident events. This procedure reduces the number of fake events considerably, by a factor $\sim 10^{-4}$ compared with the number of fake events in single detector analysis. We find that the number of events after imposing the coincidence conditions is consistent with the number of accidental coincidences produced purely by noise. We thus find no evidence of gravitational wave signals. We obtain an upper limit of 0.046 /hours (CL $= 90$) to the Galactic event rate within 1kpc from the Earth. The method used in this paper can be applied straightforwardly to the case of coincidence observations with more than two detectors with arbitrary arm directions.Comment: 28 pages, 17 figures, Replaced with the version to be published in Physical Review

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 correcte

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

Stable Operation of a 300-m Laser Interferometer with Sufficient Sensitivity to Detect Gravitational-Wave Events within our Galaxy

TAMA300, an interferometric gravitational-wave detector with 300-m baseline length, has been developed and operated with sufficient sensitivity to detect gravitational-wave events within our galaxy and sufficient stability for observations; the interferometer was operated for over 10 hours stably and continuously. With a strain-equivalent noise level of $h\sim 5 \times 10^{-21} /\sqrt{\rm Hz}$, a signal-to-noise ratio (SNR) of 30 is expected for gravitational waves generated by a coalescence of 1.4 $M_\odot$-1.4 $M_\odot$ binary neutron stars at 10 kpc distance. %In addition, almost all noise sources which limit the sensitivity and which %disturb the stable operation have been identified. We evaluated the stability of the detector sensitivity with a 2-week data-taking run, collecting 160 hours of data to be analyzed in the search for gravitational waves.Comment: 5 pages, 4 figure

大分県内の給食提供施設における宗教上の食事対応の状況について

The number of foreign residents and visitors to Japan is increasing. In 2016, foreign residents accounted for about 2% of the population. Hospitals may be required to cater for not only the diversification of inpatients, but also the diversity of religious food cultures and eating habits. The purpose of this study was to investigate the current situation regarding religious meals in hospitals in Oita Prefecture and to consider future requirements. A questionnaire survey was sent to 108 hospitals that provide school lunches to assess their knowledge of religiously diverse food cultures and eating habits. Of 60 hospitals that responded, 95% said they knew or had heard of the need for religious meals, and 69% said they had no experience of learning how to prepare religious meals. Lack of opportunity or interest was the reason. In hospitals with learning experience, they had studied as university students or as nutritionists, and it was inferred that they never had learning opportunities. In addition, 32% answered that they had hospitalized patients who required meal support. Difficulties in preparing religious meals included language barriers, availability of raw materials such as processed seasonings, and menus. On-site workers lacked information on how to prepare meals, and there is a need to provide materials for cooks and to cooperate with vendors who supply relevant products. Furthermore, there were cases in which the beliefs and preferences of individual patients were only revealed during the course of treatment when questioned by staff. Religious diets are an important issue for some patients, and it is essential that staff not only understand food culture and eating habits, but also interview patients to ensure that improvements are made that meet their needs.この調査研究は2018年度公益社団法人大分県栄養士会の調査研究費より補助を受け、実施いたしました
