构造分析表明,中部北海道是一个以北北西向褶皱和断层为特征的变形带。Jolivet等(1989)把该带解释为右行压扭剪切带,形成于渐新世—中中新世。最近,中北海道剪切带与日本海的形成关系已引起人们很大注意。我们对在距剪切带150km的Haboro和Yubasi地区出露的第三纪沉积岩作了古地磁研究,并论证了这些沉积盆地的构造变形,提出了此剪切带运动的古地磁证据。

Anisakiasis can involve any part of the digestive tract, but most cases reported have involved the stomach;few reports have described colonic anisakiasis. Furthermore, asymptomatic colonic anisakiasis has been reported to be very rare. A 58-year-old Japanese male asymptomatically received colonoscopy due to a fecal occult blood testing positive, and an Anisakis larva was removed in the ascending colon. After colonoscopy, an detailed questionings concerning eating raw fish revealed that the patient ate the liver of raw filefish 21 days before the colonoscopy. Thus, questionings concerning eating the raw fish were very important and helpful for correct diagnosis. This case report demonstrated that colonic anisakiasis can be diagnosed by colonoscopy before severe complications (intestinal obstruction, perforation, and cancer development) occur. Also, biopsy forceps could be used to remove the Anisakis worms, demonstrating that diagnosis and treatment can be simultaneously performed.

Laser–plasma interaction and hot electrons have been characterized in detail in laser irradiation conditions relevant for direct-drive inertial confinement *** experiment was carried out at the Gekko XII laser facility in multibeam planar target geometry at an intensity of approximately 3×10^(15)W/cm^(2).Experimental data suggest that high-energy electrons,with temperatures of 20–50 keV and conversion efficiencies ofηsma waves driven by two-plasmon decay(TPD).stimulated Raman scattering(sRs)is observed in a near-threshold growth regime,producing a reflectivity of approximately 0.01%,and is well described by an analytical model accounting for the convective growth in independent *** experiment reveals that both TPD and sRs are collectively driven by multiple beams,resulting in a more vigorous growth than that driven by single-beam laser intensity.

We could observe the endoluminal stent graft (sG) following thoracic endovascular aneurysm repair (TEVAR) by a coronary artery angioscope and establish intravascular visualization of sG. The patient was a 70-year-old woman with the distal aortic arch aneurysm and the descending aortic aneurysm, and debranching TEVAR were performed. After 12 months follow up, urgent hospitalization was required for chest pain, and cardiac catheter examination with a coronary artery angioscope was performed. The endoluminal sG was observed. The observation in angioscope which is a video image is better than CT that is a still image, and observation in blood vessel or sG is possible. It may be possible to observe the endoluminal sG, allowing potential investigation of an endoleak, or the covering status of the sG with the native aortic vessel wall, or the state of intimal membrane formation in the endoluminal graft.

In this study, the effect of ascorbic acid 2-phosphate (Asc2P) was tested on porcine and rat mature hepatocytes in vitro. a). Asc2P increased the porcine, but not rat, albumin secretion and mRNA expression. The enhancing effect of Asc2P on porcine C/EBP alpha mRNA was observed in porcine mature hepatocytes. These data suggested that Asc2P played an important role in the regulation of porcine albumin mRNA level. b). The enhancing effect of Asc2P on ammonium metabolic activity was also observed in porcine, but not rat, mature hepatocytes. The porcine ornithine transcarbamylase (OTC) and arginase mRNAs were augmented by Asc2P, indicating that Asc2P had a direct effect on the urea cycle. c). The porcine collagen type I and type III mRNA, but not type XII mRNA, were detected as well, sugessting that Asc2P did not have the effect on the non-parenchymal hepatocytes to induce collagen type I and III mRNA expression. d). Our RT-PCR analysis demonstrated that the porcine hepatocytes expressed the sodium-ascorbate co-transporters sVCT1 and sVCT2, however, the intensities of porcine sodium-ascorbate co-transporters sVCT1 and sVCT2 bands were not changed markedly. These findings indicated that the Asc2P had no effect on sVCT1 and sVCT2 mRNA expression. e). The enhancing effect of Asc2P on porcine albumin mRNA was inhibited by staurosporine, a portein kinase inhibitor. We conclude that the enhanced albumin mRNA by Asc2P might be due to activation of tyrosine protein kinase and/or PKC and the Asc2P enhanced porcine albumin mRNA mainly at the transcriptional step.

A 71-year-old Japanese man presented with asymptomatic, firm, brown-red papules on the dorsum of his left hand and back. A biopsy specimen revealed granulomatous infiltration consisting of multi-nucleated giant cells and histiocytes in the upper dermis. Elastic fibers were absent in the upper dermis, having been phagocytosed by giant cells. These papular elastolytic giant cell granuloma lesions regressed very well with narrow-band ultraviolet B irradiation, with only residual brown pigmentation left after treatment.

Poly（L-lactic acid）（PLLA） and poly（e-caprolactone）（PCL） have been receiving much attention lately due to their biodegradability in human body as well as in the soil, also due to their biocompatibility, environmentally friendly characteristics and non-toxicity. Morphology of biodegradable polymers affects the rate of their biodegradation. A polymer that has high degree of crystallinity will degrade at a slower rate due to the inherent increased stability. PCL homopolymer crosslinking degree increases with increasing doses of high energy radiation. On the other hand, the irradiation ofPLLA homopolymer promotes mainly chain-scissions at doses below 250 kGy. In the present work, twin screw extruded films of PLLA and PCL biodegradable homopolymers and 50：50 （w：w） blend were electron beam irradiated using electron beam accelerator Dynamitron （E = 1.5 MeV） from Radiation Dynamics, Inc. at doses in the range of 50 kGy to 103 kGy in order to evaluate the effect of electron beam radiation. Wide-angle X-ray diffraction （WAXD） patterns of non irradiated and irradiated samples were obtained using a diffractometer Rigaku Denki Co. Ltd., Multiflex model; and Fourier transform infrared spectroscopy （FTIR） spectra was obtained using a NICOLET 4700, attenuated total reflectance （ATR） technique. By WAXD patterns of as extruded non irradiated and irradiated PLLA it was verified broad diffusion peaks corresponding to amorphous polymer. There was a slight increase of the mean crystallite size of PCL homopolymer with increasing radiation dose. PCL crystalline index （CI） decreased with radiation dose above 500 kGy. But then, PLLA CI increased with radiation dose above 750 kGy. From another point of view, PLLA presence on the 50：50 blend did not interfere on the observed mean crystallite size increase up to 250 kGy. From 500 kGy to 103 kGy the crystallite size of PCL was a little bigger in the blend than the homopolymer. In contrast, FTIR results have shown that this technique was not sen
