Lipid accumulation using Oil Red O dye was measured in 3T3-L1 murine adipocytes to examine the anti-obesity effect of four types of germinated rice, including germinated brown rice (GBR), germinated waxy brown rice (GWBR), germinated black rice (GB-R), and germinated waxy black rice (GWB-R). GBR methanol extract exhibited the highest suppression of lipid accumulation in the 3T3-L1 cell line and also the anti-obesity effect of GBR on high fat induced-obese mice. The mice were divided into three groups and were administered: ND, a normal diet; HFD control, a high fat diet; and GBR, a high fat diet plus 0.15% GBR methanol extract for 7 weeks. GBR administration significantly decreased body weight gain and lipid accumulation in the liver and epididymal adipose tissue as compared to the HFD control group. In addition, serum triglycerides (TGs) and total cholesterol (TC) levels were significantly decreased by following GBR administration compared with those in the HFD control group, whereas the high-density lipoprotein (HDL) cholesterol level increased. Furthermore, the mRNA levels of adipogenic transcriptional factors, such as CCAAT enhancer binding protein (C/EBP)-α, sterol regulatory element-binding protein (SREBP)-1c, and peroxisome proliferator activated receptors (PPAR)-γ, and related genes (aP2, FAS), decreased significantly. Taken together, GBR administration suppressed body weight gain and lipid accumulation in the liver and epididymal adipocytes, and improved serum lipid profiles, in part, by controlling adipogenesis through a reduction in transcriptional factors. These results suggest that GBR is a potential agent against obesity.

本研究は, 青年期の子どもからみた両親のコミットメントに関する認知尺度を作成し, 両親間の葛藤解決および青年の不安との関連性を検討することを目的として実施された。女子青年136名 (平均20.4歳) を対象に質問紙調査を実施した。分析の結果, 両親の結婚生活に対するコミットメントの認知は, 父母いずれも「存在の全的受容・非代替性」「社会的圧力・無力感」「永続性の観念・集団志向」「物質的依存・効率性」の4因子が抽出された。このうち, 不安と比較的強い相関がみられたのは「存在の全的受容・非代替性」と「社会的圧力・無力感」であり, 両者は異なる関連にあった。すなわち, 「存在の全的受容・非代替性」を高く認知している者ほど不安は低減するのに対し, 「社会的圧力・無力感」が高い者ほど不安は強まることが示された。また両親のコミットメントと女子青年の不安の関連は居住形態によって異なり, 親と同居している場合に顕著であった。さらに両親間の葛藤解決と不安の関連は一様ではなく, コミットメントの性質によって異なる可能性が示唆された。

To investigate influence of general anesthesia on immunological anti-tumor activity, the natural killer (NK) cytotoxic activity of peripheral lymphocytes (PBLs) was measured in 7 dogs anesthetized for 3 hr with isoflurane following propofol-induction (anesthesia group) and 6 dogs without anesthesia (control group). Blood samples were collected before (baseline) and 24, 120 and 192 hr after the anesthesia. The PBLs were isolated via centrifugation with Ficoll-Hypaque solution (density, 1.073), and adherent cells were removed. The NK cytotoxic activity of the isolated PBLs against canine thyroid cancer cells was detected by the colorimetric rose Bengal assay. Significant decrease in the NK cytotoxic activity was observed at 24 hr after the anesthesia, compared with the baseline values and the control group. The NK cytotoxic activities were recovered to the baseline values until 120 hr after the anesthesia. The general anesthesia with isoflurane following propofol-induction decreased the NK cytotoxic activities of PBLs in dogs. This finding has a clinical relevance to the risk of tumor recurrence or metastasis induced by the suppression of immunological anti-tumor activity after general anesthesia in dogs. The results further emphasized the importance of the need to evaluate immune suppression following general anesthesia in animals.

MuPAT enables the users to easily treat quadruple and octuple precision arithmetics as well as double precision arithmetic on Scilab. Using external C routines, we have also developed a high speed implementation MuPAT_c for Windows, Mac OS, and Linux. MuPAT_c reduced the computation time especially for all octuple precision arithmetic and inner product of quadruple precision arithmetic. MuPAT_c can run 90-1200 times faster than MuPAT. We applied three different precisions to tridiagonalization by the Lanczos method and confirmed that a high precision arithmetic was essential for the Lanczos method to get accurate eigenvalues of real symmetric matrices.

Non-differentiability of the absolute value function at the origin can affect the accuracy of numerical computations for the $L^1$ norm. We present an example in which the accuracy does deteriorate, and we provide a convergence order for such situations. We propose a simple algorithm to improve the convergence order, confirming its effectiveness as in the example described above. Mesh-dependent integrands and applications to finite element method are also considered.

We propose a new idea for the crustal movements associated with past great Nankai earthquakes in Shikoku and the surrounding region, Southwest Japan. This study makes clear that the movements are not due to the oblique subduction of the Philippine sea plate, but due to superposition of strong seismic shaking to the uppermost crust in a compressional stress state in the E-W direction. The ground of this idea is as follows: at the time of the 1707, 1854 and 1946 Nankai earthquakes the Kochi plain subsided and the Muroto and Ashizuri peninsulas uplifted, whereas old documents show that the Kochi plain did not subside at the time of the 1605 Nankai earthquake and therefore no uplifting of the peninsulas is inferred because it is based on a set of subsidence of the Kochi plain and uplifting of the Muroto peninsula appearing at the time of the 1707, 1854 and 1946 Nankai earthquakes. This is explained by the reason why the 1605 (Keicho) earthquake was not accompanied with strong shaking of the ground owing to the tsunami earthquake. Next, because the uplifted peninsulas have anticline axes of the N-S direction, from unconsistency in stress direction it is difficult to attribute the uplifting to the subduction in the NW direction of the Philippine sea plate. On the other hand, it is easily explained that the uplifting was caused by the stress in the EW direction enhanced by strong seismic shaking. Tosa bay, which spreads between the Muroto and Ashizuri peninsulas, is characterized by depression. To be able to explain this depression is not by the elastic rebound theory, but by our idea. The undulation in the forearc zone composed of anticlines (peninsulas) and wide depressions (bays), which range alternately along the Japan island arc, can not also explained by the elastic rebound theory. In addition, we consider that the compressional strain variation in the NW direction of the ground surface observed at present in Shikoku does not result from the oblique subduction in the NW direction of the Philippine sea plate, but it is recovering the overdisplacement of the ground surface caused by the coseismic movement (2-3m at the ground surface) in the SE direction of the Muroto promontory by reverse faulting of the 1946 earthquake. Moreover, this study shows that unconsistency in directions of P axes between the 1946 Nankai earthquake and mantle earthquakes presently occurring in Shikoku and its vicinity is succesfully explained by taking account of constraint of the displacement in the direction along the Japan island arc.

At Taq-i-Bustan situated in northwest Iran, the relief of Royal Boar Hunt of the larger grotto shows the rich illustration of the late Sasanian textile designs, which decorate the garments of the figures. The sorts of the motifs and arrangements of decorative patterns on the garments are selected according to the groups of the figures.The vegetable motifs contain a lot of variations, but their forms are reduced into a few groups. The origin of floral designs of eight petals, quatrefoil leaves and chrysanthemum remounts to ancient Mesopotamian and Achaemenid art. The motif of quatrefoil rose succeeds Roman and Parthian tradition. The motif of the tree of life is a Sasanian type. Most of their forms are comparatively simple. As the main patterns of the garments, the vegetable motifs are seen only on the kings and musicians' garments.On the contrary, the bird motifs are richly seen as the main patterns of the garments. The aquatic bird motifs are seen on the rider-courtiers' garments. The cock, peacock, crane and eagle motifs are seen on the other courtiers' garments. The simurgh motif is only seen on the kings' garments. The sheep and boar head motifs are represented on the partial decorations of garments of the crews of the kings' boats. These animal motifs are not decorated with ribbons and pearl necklaces which are very popular in the Sasanian-type textile designs.In comparison with the designs of Sasanian-type textiles, the arrangements of main patterns on the garments reveal certain irregu-larities and simplifications. These arrangements are classified into several types, such as arrangements of horizontal row, symmetry, zigzag and diagonal lattice. In the Royal Boar Hunt, there are neither zigzag patterns of the roundels surrounded by a pearl ring, nor zigzag patterns of the roundels enclosing symmetrical arrangements. The simurgh pattern of the Mounted King in the lower section of the rear wall shows the most developed phase in the textile designs of Taq-i-Bustan.

In the injection molded parts of glass fiber reinforced PP (PPG), the increase of fiber content to improve the mechanical properties, results in protruding the surface at weld-line region, where melt flows unite in at injection mold, and deteriorates the surface appearance.In this study, the optimum material design were discussed to improve both surface appearance quality and mechanical property of PPG.The weld-line protrusion height as the surface appearance quality and izod impact strength as the mechanical property were measured for PPG's with various fiber contents. The influences of fiber content, short-fiber/long-fiber ratio and flowability of matrix PP were discussed. It can be found that the low-flowability PP with a proper quantity of long fiber is effective for solving the weld-line protrusion without reducing the impact strength.

A new mineral ruthenium in a concentrate from the Horokanai platinum placer, Hokkaido, is described. Electron-microprobe analysis of this mineral gave the following weight percentages: Ru 64.43, Ir 14.62, Pt 9.14, Rh 7.05, Os 5.29, Pd 0.49, Fe 0.21, Ni tr., Cu tr., total 101.23. The result corresponds to the composition Ru1.47Ir0.18Rh0.16Pt0.11Os0.06Pd0.01Fe0.01, and the proportions between three prin-cipal metals are Ru:Ir:Rh=81.5:9.7:8.8, which falls in the region of mineral ruthenium because Ru content is more than 80 atomic percent of the three elements. This mineral is, therefore, named ruthenium after its chemical composition. Reflection colour is white with light creamy tint, and reflectivity is about 60 percent. It shows optically weak anisotropism. It occurs as a tabular crystal associated with rutheniridosmium in the peripheral area of a platinum grain. The size of the crystal is 35×7 microns in polished section. The mineral ruthenium and the name have been approved by the Commission of New Minerals and Mineral Names, IMA.

It is important for myocardial infarction patients to undergo immediate reperfusion of the affected coronary artery. In order to improve the prognosis, efforts to shorten the door to balloon time to within 90 minutes have been made. However, conventional methods such as faxing electrocardiograms (ECG) have not become widespread due to their high cost and lack of sharpness of the ECG. The “Doctor Car” (rapid response car system) of Kitasato University Hospital is now equipped with a Mobile Cloud ECG system. With this system, 12-lead ECG data obtained in the field are transmitted to the cloud server via a standard mobile telephone network. Since it uses an existing phone network, the cost of this system is low and it is fairly reliable. Cardiologists at the hospital read the ECG waveforms on the cloud server and decide whether emergency cardiac catheterization is necessary. In our fi rst case using this Mobile Cloud ECG system, the door to balloon time could be shortened.

The male and female karyotypes were examined for 10 specimens of the Chinese soft-shelled turtle, Pelodiscus sinensis, from the main islands of Japan and Taiwan by the bone marrow air-dry technique. One specimen of Dogania subplana was also examined karyologically. Although both P. sinensis and D. subplana had 2n=66 chromosomes, they showed an interspecific variation in chromosome morphology. No karyotypical differences were evident between the Japanese and Taiwanese samples of P. sinensis, or within either of them. Comparisons of the present results with previously reported trionychine karyotypes indicate that there are some interspecific and intraspecific variations in centromeric positions of several macrochromosome pairs in this subfamily.

In this paper, we examine how covering one or both external ears affects sound localization on the horizontal plane. In our experiments, we covered subjects’ pinnae and external auditory canals with headphones, earphones, and earplugs, and conducted sound localization tests. Stimuli were presented from 12 different directions, and 12 subjects participated in the sound localization tests. The results indicate that covering one or both ears decreased their sound localization performance. Front-back confusion rates increased, particularly when covering both outer ears with open-air headphones or covering one ear with an intraconcha-type earphone or an earplug. Furthermore, incorrect answer rates were high when the sound source and the occluded ear that had an intraconcha-type earphone or an earplug were on the same side. We consider that the factors that cause poor performance can be clarified by comparing these results with characteristics of head-related transfer function.

日本では, 1970年代の半ば頃から, 人びとの健康への関心が高まり, それまでよりも多くの人びとが健康を維持・増進するための行動を心がけるようになったといわれている.周知のとおり, これらの現象は「健康ブーム」と呼ばれている.医療社会学では, このような「ブーム」の背景に, 「健康至上主義」の高まりを想定している.しかし, 「健康ブーム」も「健康至上主義」の高まりも, それらの存在を裏付ける証拠はいまのところ存在しない.そこで, 本論では, 書籍ベストセラーが人びとの意識や関心を反映しているとの仮定のもとに, 健康に関するベストセラーの戦後の変遷を分析することを通して, 人びとの健康についての意識の程度やあり方の変化を探った.その結果, 健康に関する本のベストセラーは1970年代の半ばに初めて登場したわけではなく, 1950年代後半から今日まで, そう変わらない頻度で現れていることが見出された.また, 「健康ブーム」といわれる時期の初期およびその直前には, 医学をわかりやすく解説する啓蒙書がベストセラーになっていることが発見された.したがって, 1950年代後半から今日まで, 人びとの健康への関心の程度にはそれほど変化がないということになる.また, 「健康ブーム」とされる時期に特徴的なことは, 健康への関心の高さではなく, むしろ, 健康に良いと信じられていることに対する批判的な意識の高まりではないかと推測される.

Two dogs that exhibited sudden astasia, anorexia and fever higher than 40°C were suspected of having Lyme disease in July 2011. Clinical symptoms gradually improved with antibiotic treatment in both cases. Polymerase chain reaction and sequence analysis revealed Borrelia garinii DNA fragments in the peripheral blood in the acute disease phase. Serological tests, including enzyme linked immunosorbent assay and Western blot analysis, showed an increased IgG antibody titer against Borrelia pathogens in one of the dogs. These findings suggested that diagnosis of the two dogs were Lyme disease related to B. garinii infection.

An association between psychological factors and diabetes has been suspected for a long time. However, epidemiological data on this association is limited. We investigated the association between psychological factors (perceived mental stress and type A behavior) and the onset of diabetes in a community-based, prospective cohort study in a large number of middle-aged Japanese adults. A total of 55,826 subjects (24,826 men and 31,000 women) aged 40-69 years were followed for 10 years. A self-administered questionnaire on medical conditions including diabetes and other lifestyle factors was performed at baseline and 5 and 10 years later. Psychological factors and diabetes were assessed based on the questionnaire results. During the 10-year follow-up period, we documented 1,601 incident cases (6.4%) of diabetes among men and 1,093 cases (3.5%) among women. The risk of diabetes increased with an increasing stress level, especially among men. Multivariate adjusted odds ratios for high stress compared with low stress were 1.36 (1.13 to 1.63) among men and 1.22 (0.98 to 1.51) among women. The risk of diabetes increased with an increasing level of type A behavior only among women. Multivariate adjusted odds ratios for high levels of type A behavior compared with low levels of type A behavior were 1.09 (0.94 to 1.27) among men and 1.22 (1.01 to 1.47) among women. We found an association between perceived mental stress and the incidence of diabetes, especially among men. We also found an association between type A behavior and the incidence of diabetes among women. In addition, inverse association between coffee consumption and the incidence of diabetes which was consistent with other studies was observed.
