In Tokyo Metropolitan University, the horizontal and vertical array earthquake observations has begun in June 1994 at the five stations （kl-k5） on the ground surface and bedrock （k6：-30 m depth） at Zushi-site. More than 200 medium and small earthquakes with the magnitude 5.0-7.3 were recorded between 1994 and 2012. At the 2011 off the Pacific coast of Tohoku Earthquake （EQ.3.11 M = 9.0）, the largest surface ground acceleration （kl = 124.5 gal, k6 = 45.5 gal） of the horizontal component was recorded. Main results were obtained as follows：（1） the surface ground motion characteristics of Zushi-site were examined using the observed data （kl ＆ k6） of EQ.3.11, the past-observed smaller earthquakes （EQ.1 ＆ EQ.10.08） and aftershock （EQ.12.3）, respectively. The non-liner seismic response characteristics of the surface ground at Zushi-site were verified during EQ.3.11. （2） The ground structure models were examined and identified by the modal analyses and the FEM （finite element method） identification analyses using the observed acceleration data of EQ.3.11 and the past observed smaller earthquakes. （3） Moreover, the three dimensional seismic response analyses were performed by TDAPUl （time domain 3-dimensional dynamic analysis program）, using k6 for input motions and identified ground structure model, and evaluated the dynamic behaviours of the surface ground. The calculated results agreed well with the observed ones.

AIM： To examine the association of inducible nitric oxide synthase （iNOS） C150T polymorphism with gastric cancer, as well as with gastric atrophy and H pylori ***： A single nucleotide polymorphism of iNOS CtSOT was examined for 454 Japanese health checkup examinees （126 males and 328 females） aged 35 to 85 years without a history of cancer and 202 gastric cancer patients （134 males and 68 females） aged 33 to 94 years with pathologically confirmed diagnosis of gastric adenocarcinoma.RESULTS： The iNOS C150T polymorphism was not associated with gastric atrophy or with H pylori seropositivity. The odds ratio （OR） of the C/T ＋T/T for gastric cancer was increased without statistical significance （OR=1.19, 95% confidence interval （CI）： 0.68-2.08）. In the differentiated subgroup （n = 113）, however, the OR of the C/T genotvpe for gastric cancer was significant （OR = 2.02, 95% CI： 1.04-3.92） relative to the C/C genotype. In addition, considering the location of gastric cancer （n = 105）, there were significant differences between the controls and non-cardia group with the ORof 2.13 （95% CI： 1.08-4.18） for C/T and 1.94 （95% CI： 1.00-3.78） for C/T ＋ T/***： The iNOS C150T polymorphism is associated with the risk of H pylori-related gastric cancer in a Japanese population. This polymorphism may play an important role in increasing the risk of gastric cancer in Asian countires with the highest rates of gastric cancer.

Functionalization of silica nanoparticles for nucleic acid delivery

引用

Nano Research 2018年第10期11卷 5219-5239页

作者： Rimpei Kamegawa Mitsuru naito Kanjiro Miyata Department of Materials Engineering Graduate School of Engineering The University of Tokyo Tokyo 113-8656 Japan Center for Disease Biology and Integrative Medicine Graduate School of Medicine The University of Tokyo Tokyo 113-0033 Japan

Silica nanoparticles （SiNPs） have been widely engineered for biomedical applications, such as bioimaging and drug delivery, because of their high tunability, which allows them to perform specific functions. In this review, we discuss the functionalization and performance of SiNPs for nucleic acid delivery. Nucleic acids, including plasmid DNA （pDNA） and small interfering RNA （siRNA）, constitute the next generation molecular drugs for the treatment of intractable diseases. However, their low bioavailability requires delivery systems that can circumvent nuclease attack and kidney filtration to ensure efficient access to the target cell cytoplasm or nucleus. First, we discussed the biological significance of nucleic acids and the parameters required for their successful delivery. Next, we reviewed SiNP designing for nucleic acid delivery with respect to nucleic acid loading and release, cellular uptake, endosomal escape, and biocompatibility. In addition, we discussed the co-delivery potential of SiNPs. Finally, we analyzed the current challenges and future directions of SiNPs for advanced nucleic acid delivery.

Comparison of the effects of cold water and ice ingestion on endurance cycling capacity in the heat

引用

Journal of Sport and Health Science 2017年第1期6卷 111-117页

作者： Takashi naito Tetsuro Ogaki Graduate School of Human-Environment Studies Kyushu UniversityFukuoka 40218Japan

Purpose: The purpose of this study was to examine the effects of pre-cooling and fluid replacement with either crushed ice or cold ***: On 2 separate occasions, in a counterbalanced order, 9 recreationally-trained males ingested 1.25 g/kg(80–100 g) of either crushed ice(0.5℃)or cold water(4℃) every 5 min for 30 min before exercise. They also ingested 2.0 g/kg(130–160 g) of the same treatment drink at 15 min, 30 min, and45 min after the commencement of cycling to exhaustion at 60%VO_(2max) until voluntary exhaustion in a hot environment(35℃ and 30% relative humidity).Results: The cycling time to exhaustion in the crushed ice trial(50.0 ± 12.2 min) was longer than the cold water trial(42.2 ± 10.1 min; p = 0.02).Although the rectal temperature fell by 0.37℃± 0.03℃(p = 0.01) at the end of the resting period after the crushed ice ingestion, the rates of rise in rectal temperature during the exercise period were not significantly different between these 2 conditions(crushed ice: 0.23℃± 0.07℃, 5 min;cold water: 0.22℃± 0.07℃, 5 min; p = 0.94).Conclusion: Crushed ice ingestion before and during exercise in a hot environment may be a preferred and effective approach for minimizing thermal strain, and for improving endurance performance as compared with cold water ingestion.

Liquid Immiscibility of Boninite in Xiangcheng, Southwestern China, and Its implication to Genetic Relationship between Boninite and Komatiitic Basalt

引用

Acta Geologica Sinica(English Edition) 2001年第1期75卷 74-93页

作者： Tetusro Urabe Takagi naito Geological Survey of Japan Ibaraki 305 JapanGeological Survey of Japan Ibaraki 305 JapanGeological Survey of Japan Ibaraki 305 Japan

Boninitic rocks and associated high-magnesian basalt and high-iron tholeiite in the Xiangcheng area constitute the basal horizon of the arc volcanic sequence in the Triassic Yidun Island-Arc, southwestern China. The boninite occurs as pillow, massive and ocellar lavas; the last one possesses well-developed globular structure and alternates with the former two. The boninite is characterized by the absence of phenocrysts of olivine and low-Ca pyroxenes and by low CaO/Al2O3 ratios (1000 ppm) and Ni (>250 ppm). The normalized abundance patterns (NAP) of trace elements to primitive mantle are similar to the NAP of low-Ca modern boninites and SHMB in the Archaean and Proterozoic.

Radical Reactions and Its Synthetic Application

引用

复旦学报（自然科学版） 2005年第5期44卷 758-759页

作者： Takeaki naito Medicinal Chemistry Laboratory Kobe Pharmaceutical University Kobe 658-8558 Japan

Strategies involving radical reactions have become preeminent tools in organic synthesis. Free radical-mediated cyclization has developed as a powerful method for preparing various types of cyclic compounds via carbon-carbon bond-forming processes. In order to develop effective and convenient methods for the synthesis of biologically active cyclic amines, we have focused our efforts on radical reactions using aldehydes, ketones,and C-C multiple bonds as a radical precursor and/or an oxime ether, hydrazone, and nitrone as a radical acceptor. In this lecture, I would like to talk on radical addition-cyclization of oxime ether and its application to the synthesis of martinellines.

Nestin in gastrointestinal and other cancers: Effects on cells and tumor angiogenesis

引用

World Journal of Gastroenterology 2011年第4期17卷 409-418页

作者： Toshiyuki Ishiwata Yoko Matsuda Zenya naito Department of Pathology Integrative Oncological Pathology Nippon Medical School

Nestin is a class Ⅵ intermediate filament protein that was originally described as a neuronal stem cell marker during central nervous system (CNS) development, and is currently widely used in that capacity. Nestin is also expressed in non-neuronal immature or progenitor cells in normal tissues. Under pathological conditions, nestin is expressed in repair processes in the CNS, muscle, liver, and infarcted myocardium. Furthermore, increased nestin expression has been reported in various tumor cells, including CNS tumors, gastrointestinal stromal tumors, pancreatic cancer, prostate cancer, breast cancer, malignant melanoma, dermatofibrosarcoma protuberances, and thyroid tumors. Nestin is reported to correlate with aggressive growth, metastasis, and poor prognosis in some tumors; however, the roles of nestin in cancer cells have not been well characterized. Furthermore, nestin is more specifically expressed in proliferating small-sized tumor vessels in glioblastoma and gastric, colorectal, and prostate cancers than are other tumor vessel markers. These findings indicate that nestin may be a marker for newly synthesized tumor vessels and a therapeutic target for tumor angiogenesis. It has received a lot of attention recently as a cancer stem cell marker in various cancer cells including brain tumors, malignant rhabdoid tumors, and uterine, cervical, prostate, bladder, head and neck, ovarian, testicular, and pancreatic cancers. The purpose of this review is to clarify the roles of nestin in cancer cells and in tumor angiogenesis, and to examine the association between nestin and cancer stem cells. Nestin has the potential to serve as a molecular target for cancers with nestin-positive cancer cells and nestin-positive tumor vasculature.
