A fecal microbial community structure in pigs fed with fermented liquid feed was investigated. The phylogenetic diversity of the fecal microbial community in pigs was analyzed by the PCR-clone ...library study and PCR-DGGE analysis. The V3 region of 16s rDNA was amplified by PCR using total DNA extracted from pig feces as a template. A clone library comprising of 120 cloned 16s rDNA sequences was classified into 39 ribotypes by RFLP analysis, and all clones were found to belong to Bacteroides, Spirochaetes, and Firmicutes. The abundance ratio of Firmicutes increased greatly from 66.7% to 83.3% for a pig fed with fermented liquid feed. From the results of PCR-DGGE, Pig26 clone that belongs to Firmicutes showed a marked increase. Because the homology between 16s rDNA of a known bacterium and Pig26 clone was low ( 86%) as analyzed by Blast, we could not identify the Pig26 clone. Therefore, it was impossible to presume a feeding effect of fermented liquid feed based on a dominant organism name. On the other hand, the gastric acid resistance of Lactobacillus plantarum A305 used as a starter was insufficient. Therefore, Lactobacillus plantarum A305 was hardly able to grow in the digestive organ. Taking all together, the change in a pig's microbial community due to Lactobacillus plantarum A305 was slight and that change did not influence the pig's health.
A conversion method for liquid feed for pigs by lactic acid fermentation was investigated for the purpose of recycling food by-products generated from food companies in Hiroshima prefecture. Batch ...cultivations were performed to obtain the growth properties such as specific growth rate (micro), growth yield from glucose (Yx/s) and lactic acid yield from glucose (Yp/s) at 30 or 38 deg C, using three types of lactic acid bacterium. Moreover, the possibilities of utilization of starch and stomach acid tolerance and bile tolerance of lactic acid bacteria were also examined. From the results, Lactobacillus plantarum A305 was shown to have the highest aptitude. A305 had both high growth rates and greater possibilities for utilizing starch compared with the other two. Furthermore, A305 had large growth rates in both of a rice-cleaning drainage culture medium used a pre starter and as a food by-products culture medium of the same composition as liquid feed.

Diamond metal-insulator-semiconductor field-effect-transistors (MISFETs) utilizing a hole accumulation layer have been fabricated on a hydrogen-terminated (H-terminated) diamond surface. The highest ...cut-off frequency (f T ) of 30 GHz and the maximum frequency of oscillation (f max ) of 60 GHz were obtained in the 0.35 mum gate diamond MISFET. RF power operations of diamond MISFETs were demonstrated for the first time. In RF power operation, the high power density of 2.14 W/mm was obtained at 1 GHz
We report on the ASCA X-ray spectra from the north rim and the center of the supernova remnant (SNR) G156.2+5.7. The spectra are found to comprise soft and hard X-ray components. No clear shell ...structure has been found, either in the soft or in the hard X-ray bands. The soft X-rays are attributable to a non-equilibrium ionization plasma with a temperature of 0.4 keV and an ionization timescale of 1011.0−11.2 cm−3s. A Sedov solution with an explosion energy of 1051 erg leads to an age of ∼ 1.5 × 104 yr and a density of ambient gas of ∼ 0.2 cm−3. The distance to G156.2+5.7 is estimated to be ∼ 1.3 kpc. The abundances of silicon and sulfur vary between the center and the north rim of the SNR, while the abundances of all other elements do not. The hard component can be modeled with either thermal emission of a temperature higher than a few keV or a non-thermal process with a power-law spectrum of photon index 1.5–1.8. Since the former model requires an uncomfortably high temperature, we favor a non-thermal model. We also discuss the nature of a point source found at the edge of the SNR.
The patency of the anastomosed blood vessels in a free vascularized bone graft is difficult to ascertain during the early postoperative stage. For this purpose, the local blood flow was measured by ...means of electrochemically generated hydrogen. Although only three cases have been tested thus far, the method proves to be a simple and useful monitor of the blood flow in a free vascularized bone graft.

We measured the correlation between the two excitons in the coupled quantum dots by the photoluminescence using two color synchronously-locked pico-second lasers and observed unique correlation ...phenomena when both excitons are excited simultaneously.
Cardiac function and hemodynamics were evaluated in ten dogs with right ventricular infarction assisted by PABP alone (Group II) or PABP with synchronized blood flow (Group III). In group II, PABP ...decreased CVP, RA pres. and RVEDP significantly and also aortic flow, RV max dp/dt and RV mp were increased. But these parameters didn't return to control values. In group III, each parameter improved remarkably and return to almost control value. Therfore, PABP with synchronized blood flow assist significantly improve acute right ventricular failure (followed by improvement of left ventricular function) and could be effective for severe right ventricular failure.
