Study Design: Retrospective cohort study. Purpose: This study aimed to investigate relationships between clinical outcomes and radiographic parameters in patients with pseudoarthrosis after posterior lumbar interbody fusion (PLIF). Overview of Literature: In some patients with pseudoarthrosis after PLIF, clinical symptoms improve following surgery, although pseudoarthrosis can often be one of the complications. However, there are no previous reports describing differences between patients with pseudoarthrosis after PLIF who have obtained better clinical outcomes and those who have not. Methods: Twenty-seven patients who were diagnosed with pseudoarthrosis after single-level PLIF with cortical bone trajectory screw fixation (CBT-PLIF) were enrolled in this study. They were divided into two groups based on mean improvement of 22 points on the Oswestry Disability Index (ODI) at the 2-year follow-up. Group G consisted of 15 patients who showed improvement on the ODI of ≥22 points, and group P consisted of the residual 12 patients. Radiographic parameters, percentage of slip, lumbar lordosis (LL), segmental lordosis, segmental range of motion, screw loosening, and subsidence were compared between the two groups. Results: There were no significant differences between the two groups on radiographic parameters except for postoperative changes in LL. Although surgery-induced changes in LL showed no significant difference between the two groups, changes in LL from before surgery to 2-year follow-up and during postoperative 2-year follow-up were significantly better in group G (mean change of LL: +3.5° and +5.1°, respectively) compared to group P (mean change of LL: −4.6° and −0.5°, respectively) (p<0.01 and 0.05, respectively). Conclusions: Patients with greater improvement in ODI gained LL over the 2-year follow-up, whereas patients with less improvement in ODI lost LL during the 2-year follow-up. These results indicate that there is a significant correlation between clinical outcomes and LL even in patients with pseudoarthrosis after single-level CBT-PLIF.

Yamagishi, M.,Kaneda, H.,Oyabu, S.,Ishihara, D.,Onaka, T.,Shimonishi, T.,Suzuki, T. The Korean Astronomical Society 2012 天文學論叢 Vol.27 No.4

The absorption features due to interstellar ices, especially $H_2O$ and $CO_2$ ices, provide us with crucial information on present and past interstellar environments, and thus the evolutionary histories of galaxies. Before AKARI, however, few detections of ices were reported for nearby galaxies. The AKARI's unique capability of near-infrared spectroscopy with high sensitivity enables us to systematically study ices in nearby galaxies. Thus we have explored many near-infrared spectra ($2.5-5{\mu}m$) of the 211 pointed observations, searching for the absorption features of ices. As a result, out of 122 nearby galaxies, we have significantly detected $H_2O$ ice from 36 galaxies and $CO_2$ ice from 9 galaxies. It is notable that the ices are detected not only in late-type galaxies but also in early-type galaxies. We find that $CO_2$ ice is more compactly distributed near the galactic center than $H_2O$ ice. Finally, we suggest that the gas density of a molecular cloud and UV radiation may be important factors to determine the abundance of ices.

Airphoto Interpretation and GIS Analyses of the Landslides by 2018 Hokkaido Iburi-Tobu Earthquake

( Yamagishi Hiromitsu ),( Junko Iwahashi ) 대한지질공학회 2019 대한지질공학회 학술발표회논문집 Vol.2019 No.2

An intensive earthquake (M6.7) happend in Hokkaido Iburi-Tobu area on September 6th, 2018. This earthquake triggered many landslides in 20km × 20km area and claiming 36 people lives. The author interpretd the ortho photographs by Geogrphical Institute Survey (GSI), Japan, and inventoried about 10,000 sites of the landslides and classified three types such as 1) Spoon type (S), 2) Planar type (P) and 3)Jisuberi type (J). The landslide area is composed of Neogene sedimnary rocks and covering Quaternary pumice and ash up to several meters thick. Therefore, the sliding landslide materials are mainly the pumice and ash, defined by P and S type. However, the southern area is characterized by deep-seated landslides defined as dip-slipping of Neogene bed rocks. And then, we were trying the GIS Analyses by ArcGIS 10.2 for the relationship between the landslide frequency and topographic and geologic factors. The topographic factors are derived from 10m _DEM downloaded from GSI and geologic ones from digital geologic map of Hokakido by Engineering Geologic Society of Hokkaido, Japan. As the results, we revealed that most of the landslides of S type and P type occurred at the slope gradients ranging from 25-35 degrees, and in places, the slope gradients steepend at maximum 5 degree, possibly by the erosion of the landsliding, and that debris of the Jissuberi type took place along the 10-20 degrees of stratum dipping of the Neogene Formations, as well as old Jisuberi.

DIFFERENCE IN THE SPATIAL DISTRIBUTION BETWEEN H ₂ O AND CO ₂ ICES IN M 82 FOUND WITH <i>AKARI</i>

Yamagishi, Mitsuyoshi,Kaneda, Hidehiro,Ishihara, Daisuke,Oyabu, Shinki,Onaka, Takashi,Shimonishi, Takashi,Suzuki, Toyoaki,Minh, Young Chol IOP Publishing 2013 ASTROPHYSICAL JOURNAL LETTERS - Vol.773 No.2

<P>With AKARI, we obtain the spatially resolved near-infrared (NIR) (2.5-5.0 mu m) spectra for the nearby starburst galaxy M 82. These spectra clearly show absorption features due to interstellar ices. Based on the spectra, we created the column density maps of H2O and CO2 ices. As a result, we find that the spatial distribution of H2O ice is significantly different from that of CO2 ice; H2O ice is widely distributed, while CO2 ice is concentrated near the galactic center. Our result reveals for the first time variations in CO2/H2O ice abundance ratio on a galactic scale, suggesting that an ice-forming interstellar environment changes within a galaxy. We discuss the cause of the spatial variations in the ice abundance ratio, utilizing spectral information on the hydrogen recombination Br alpha and Br beta lines and the polycyclic aromatic hydrocarbon 3.3 mu m emission appearing in the AKARI NIR spectra.</P>

New food material "Rosa rugosa petal" with strong anti-oxidant activity We have recognized that administration of the flower of R. rugosa reduced the odor of mouse's feces. Thus, we supposed that it must be effective for human, and the effect was proved by the experiments of volunteer. Moreover, it was proved to be effective for aging odor of human. The effects must be due to anti-oxidative activities of R. rugosa. Ear wax was collected from volunteer, 50 year old or more, and the ether extract of the wax was analyzed by GC-MS for detection of 2-nonenal. 2-Nonenal was detected in the ear wax of few volunteers, but the administration of 2 capsules containing 100mg of R. rugosa per day reduced the 2-nonenal under detection limit. These results were patented in Japan(JP No.4008369), and a new company, Harunire bio laboratory Co., was established in Kitami Institute of Technology in 2003 for development of new products. The active constituents in R. rugosa supposed to be polyphenols, hydrolysable tannnins, such as rugosin A, tellimagrandin, and the contents of these polyphenols exceed more than 20% in dry flower of R. rugosa. The flower of R. rugosa was also shown to inhibit many enzymes, such as α-amylase and α-glucosidase, and prevent intestinal disorder. Various physiological activities are evaluated using isolated polyphenols now. Product development of new functional foods from onion (Sun Onion) The amount of onion production in the Abashiri-Kitami area is about 30% of Japan. Thus, the research for development of functional foods using onion was started for the increment of onion consumption. The following new results were obtained (JP No.3697524). The flavonoids in the juice and the squeezing residue resulted in process of onion juice manufacture were analyzed, and large amount of quercetin and its glycosides were shown to remained in the squeezing residue. The amounts of flavonoids in the residue are 5-10 times of those in the juice. Moreover, the squeezing residue contains insoluble dietary fibers, and it must be expected to improve of intestinal disorders. The irradiation of light (2500lux) on onion in artificial weather machine increased the amount of quercetin eight times. Thus, the new food material using the squeezing residue after the irradiation of sunlight, stronger than artificial light was developed. The amount of flavonoid (total quercetin) was shown to exceed 800mg/100g, and the amount of the pectin was about 10g/100g, these contents were extremely higher than those without irradiation. Moreover, α-glucosidase inhibitor was isolated from onion irradiated by sunlight, and the activity of irradiated onion was shown to be twice of that of without irradiation. Breeding of new onion rich in functional constituents We analyzed flavonoids by HPLC in 15 kinds of onions cultivated in Hokkaido Kitami Agricultural Experiment Station, and 15 kinds onions cultivated in Sapporo Agricultural Experiment Station. Total flavonoids contents of edible part of these onions were 24~293mg/100g, and those in outer peel were 265~5,613mg/100g. The onion breed with high flavonoids contents was discovered. The cultivation characteristic and the processing characteristic are now under investigation. In a human clinical trial, the R. rugosa petal was proven to decreased neutral fat (triglycerides). The R. rugosa petal must to be commercialized as the functional food and cosmetic product. In the case of sunlight onion, applications for vegetable juice and function food are under investigation.

To determine the effect of exogenous 1,25-dihydroxyvitamin D3 [1,25(OH)2D3] combined with induced parturition on calcium (Ca) metabolism, cows received a single intramuscular injection of 1,25(OH)2D3 and prostaglandin F2α (PGF2α) closely before calving. Ten late-pregnant, multiparous Holstein cows were assigned to 1,25(OH)2D3 group (five treated with both 1,25(OH)2D3 and PGF2α) and control group(five treated with PGF2α). 1,25(OH)2D3 group showed an increase in plasma Ca concentration around parturition, whereas control group revealed a decrease in plasma Ca level. Plasma Ca concentration in 1,25(OH)2D3 group were significantly higher than that in control group during –0.5 to 3 days after parturition.

STUDY OF CO2/H2O ICE ABUNDANCE RATIOS IN NEARBY GALAXIES WITH THE AKARI NEAR-INFRARED SPECTROSCOPY

MITSUYOSHI YAMAGISHI,HIDEHIRO KANEDA,SHINKI OYABU,DAISUKE ISHIHARA,TAKASHI ONAKA,TAKASHI SHIMONISHI,Toyoaki Suzuki 한국천문학회 2017 天文學論叢 Vol.32 No.1

We study $\mathrm{CO_2/H_2O}$ ice abundance ratios in nearby galaxies using $AKARI$ near-infrared slit spectroscopy. Past studies of the ices intensively examined $\mathrm{CO_2/H_2O}$ ratios mainly in our Galaxy, and found that there were considerable variations in the $\mathrm{CO_2/H_2O}$ ratios from object to object. The cause of the variations is, however, still under debate. As a result of the analysis of our sample that includes 1031 regions in 158 galaxies, the $\mathrm{CO_2/H_2O}$ ratios are in a range of 0.05--0.30. In the dataset, we find that the $\mathrm{CO_2/H_2O}$ ratios positively correlate with the Br$\alpha$/PAH 3.3 $\mu$m ratios which reflect the massive star formation activity. Furthermore, we find that the $\mathrm{CO_2/H_2O}$ ratios positively correlate with the specific star formation rates of the galaxies where the ices are detected, that reflect the evolutionary stage of a galaxy. These results suggest that the $\mathrm{CO_2/H_2O}$ ratios are enhanced in active star-forming regions and young galaxies.
