    This report presents the survey data in the period, from Jan. 1 to Dec. 31, 1997 on the radioactivities in foods and environmental materials in Kanagawa Prefecture as well as uranium levels in the regions around a nuclear fuel processing plant (Japan Nuclear Fuel Co., Ltd. JNF). In this survey, radiometric determination was carried out using γ-spectroscopy for rain water, tap water, agricultural and livestock products and marine products, and their spacial radiation dose rates were determined. Monitoring of the uranium level was conducted with Undaria pinnatifida, a kind of seaweed taken from river water, bottom sediments and estuary area. In the food samples and the falling materials, 137 Cs was detected within a similar range to that of the samples collected in the previous year. The uranium levels of the samples taken around JNF were within an ordinary range, indicating that there was no significant influence of the facility on the radiological environment. (M.N.)

    This report summarizes the results of 1-year survey on the radioactivities in foods and environments in Kanagawa Prefecture and the uranium level in the surroundings of Japan Nuclear Fuel Co., Ltd. (JNF), a nuclear fuel processing plant. The survey of radioactivity or radiation level was made in environments and foods including rain water, tap water, agricultural and livestock products, marine products, etc. For these subjects, analysis of nuclides and determination of spatial radiation dose rate were performed using γ-ray spectrometer. Only for rain water, the general β level was also determined. The uranium levels was monitored in river water and bottom materials, soil, Undaria pinnatifida, a seagrass in river mouths, etc. The present results show that there was no problem for all subjects tested in respect of radioactivity. And the uranium level around JNF was also within the normal range. The mean intake of 137 Cs was 0.085 Bq/Kg/day for the residents in the district of Hiratsuka Health Center and 0.077 Bq/Kg/day for those in the Yokohama city. Both levels were slightly higher than the previous ones. The survey results before and after the returns of nuclear powered ship were also within the normal range. (M.N.)

  4. Imaging the Rural: Modernity and Agrarianism in Hiroshi Hamaya’s ‘Snow Land’ Photographs

    Full Text Available This article analyses the Snow Land photographic series by Japanese photographer Hiroshi Hamaya [1915–1999] in relation to issues of modernity, nostalgia and discourses of agrarianism in 1940s and 1950s Japan. Hamaya is one of Japan’s most celebrated and influential documentary photographers at both a national and international level. His Snow Land series presents an idyllic view of life in the small mountain villages of Japan’s Niigata Prefecture, emphasising a sense of community and spiritual meaning that Hamaya perceived to be lacking in modern society. In this sense, Snow Land constituted a critique of modernity. Through engagement with theorists such as Heidegger, Foucault and Barthes, as well as critical writings on agrarian ideology, this article investigates the underlying assumptions that govern Hamaya’s depiction of snow country, demonstrating that the series is shaped by a modern worldview and is tied to ideological discourses of agrarianism.

  5. Transposition of the Scientific Elements in Hiroshi Teshigahara’s Adaptation of Kobo Abe’s the Face of Another

    Full Text Available This article focuses on Hiroshi Teshigahara’s film adaptation of the famous Kobo Abe’s The Face of Another with special attention on the transposition of the scientific elements of the novel in the film. This article observes how Teshigahara, through cinematic techniques, transposes Abe’s scientific language into visual forms. Abe himself involved in the film adaptation by writing the screenplay, in which he prioritized the literary aspects over the filmic aspect. This makes the adaptation become more interesting because Teshigahara is known as a stylish filmmaker. Another noteworthy aspect is the internal dialogues domination within the novel narration. It is written in an epistolary-like narration, placing the protagonist as a single narrator which consequently raises subjectivity. The way Teshigahara externalizes the stream-of-consciousness narration-like into the medium of film is another significant topic of this essay.

    The concentrations of 137 Cs and the other radionuclides in dairy products, fish, vegetables, rice and total diets collected at several locations of Kanagawa Prefecture, were determined with gamma ray spectrometry during the period between 1974 and 1990. The concentration of 137 Cs in some kinds of food declined step by step from 1974 to 1985. The high concentration of 137 Cs was considerably due to some atmospheric Chinese nuclear tests. A spectacular increase in concentrations of 137 Cs, 131 I etc. in food was observed during the month of May 1986, about a week after the Chernobyl nuclear reactor accident. The concentation of 131 I in fresh milk decreased with a half-time of about 4 days. The concentrations of 137 Cs and 134 Cs in European and West Asian imported foods in the markets of some locations within Kanagawa Prefecture were determined after the Chernobyl nuclear reactor accident. The average concentration of 137 Cs in Pasta samples over a four-year period was about 10 Bq/(kg as received). (author)

    The solanaceous fruit crop pepino ( Solanum muricatum Ait.), originating in the Andes, is grown commercially in South American countries and New Zealand. In these areas, pests and diseases of pepino have been identified well; however, to date, these have seldom been investigated in detail in Japan. Herein, we attempt to reconstruct an agricultural production system for commercial pepino crops in Japan, and evaluate the incidence of pests and viral diseases on pepino. The findings of this study will facilitate in developing a better crop system for the commercial cultivation of healthy pepino fruits. A total of 11 species, comprising nine insects and two mites, were recognized as pests of pepino plants in our experimental fields in Kanagawa Prefecture, central Honshu, Japan. Of these pest species, the two-spotted spider mite Tetranychus urticae Koch, 1836 and the cotton aphid Aphis gossypii Glover, 1877, were remarkably abundant than the other pest species. Eventually, 13 species, including two previously recorded, are currently recognized as the pests of pepino in Japan. With regard to viruses, we tested two species Alfalfa mosaic virus (AMV) and Cucumber mosaic virus (CMV), as well as three genera Carlavirus , Potexvirus , and Potyvirus . No virus was detected in symptomatic pepino leaves collected in our experimental fields. This is a first report on the identification of pests on pepino plants in Kanagawa Prefecture, Japan and elucidates the relationship between currently occurring pests of pepino plants and potential viral pathogens that they can transmit.

    An online social survey was conducted to reveal household electricity-saving behaviour and its relationship with participation in social group activities, as well as face-to-face and online social interactions, i.e., information sources used and information dissemination through personal networks, in a disaster-affected region of Kanagawa, Japan, during the summer of 2011. The study confirms the positive contribution of respondents’ participation in social group activities to the number of power-saving practices conducted. It also reveals the emergence of voluntary social face-to-face and/or online interactions for power-saving. The study suggests it would be useful to provide effective information to proactive individuals who are closely engaged in power-saving in households and who are proactively disseminating power-saving information practices to others. Such individuals include (1) women who have school-children and who are proactively engaging in the social interactions of their children’s schools, other parents, neighbours, as well as their own parents and relatives; and (2) men and women who are using various kinds of online interaction tools and are also engaged in face-to-face social interactions

    As a famous historian and Oriental history scholar in modern Japan, Ikeuchi Hiroshi made great achievements in his life, especially in the fields of Manchu history and Korean history. He is the pioneer who studied Japanese history and Oriental history through new methods of historical research in Europe and America. His ideas of ' doubt ' and ' distinguishment ' towards historical materials in "Studies in the Ancient History of Japan" provided guides for historical research. However, there were some questions in the book as well, because of the times ' and personal limitations. For example, both "Nihon Shoki" and the national power of Japan in fourth century lacked enough textual research on annals.%日本近代著名的历史学家、东洋史学家池内宏在《日本上古史研究---日鲜关系与日本书纪》中体现出的对史料的质疑与辨伪的思想,对史学研究具有重要的指导作用。但由于时代及个人局限,书中同样存在一些问题。如对《日本书纪》中纪年考辨不足,对四世纪日本国力考辨不足等。

    The result of a photovoltaic power generation field test in fiscal 1996 on a prefectural office building in a sunshine-rich district is reported. It is a lighting power source installed in fiscal 1994 on the third-floor rooftop of the management information building of Kanagawa Prefectural Industrial Technology Research Institute. It has a capacity of 25kW, operating on system interconnection (no back flow), and has a single 15-series/26-parallel array (mono-crystal modules) facing 38deg westward from due south and inclined at an elevation angle of 20deg. From the 240000kWh insolation that contributed to power generation, a DC power output of 28000kWh was obtained, output of 25000kWh after conversion into AC. The module efficiency was 10.8-13.8%, higher when the daily mean temperature was lower. In the case of 3kW type expected to diffuse into the residential and commercial sector and household sector, one will output 3000kWh a year, which is an appropriate capacity as a locally distributed type power generating system in view of the monthly consumption of 2000kWh by a household in general in the Tokyo Electric Power Co., Ltd. service area. No problem is found in reliability of the tested system. Although the power it generates is less than what this office consumes, it is effective in enlightening people about resources saving and peak cut in summer

    Sinusoidal inverters are getting more widely used keeping pace with the development of semiconductor switching elements. This paper discusses optimizing a PWM pulse pattern at an inverter output to drive an induction motor, proposes methods for improving distortion and torque ripples using a carrier frequency modulation (CFM), and describes a method for realizing the improvement through use of a single-chip microcomputer. The method defines evaluation parameters corresponding to the distortion and torque ripples, and optimizes the CFM depth to the parameters. The PWM pulse pattern has its voltage vector and time width so selected that the time integrated space vector of a three-phase voltage approaches a circular locus. Furthermore, the carrier frequency, that is the sampling frequency of the inverter, is also adjusted so that the above evaluation parameters are minimized. The addition of a new variable called the frequency modulation provides freedom in selecting an output characteristic as called for by the purpose. 12 refs., 18 figs.

    The suspended particulate matters collected in 100 periods from 2002/10/28 to 2004/10/29 were separated into the water soluble and insoluble components and their main components were analyzed. The characteristics of atmosphere in the east part of Kagawa prefecture and of the secondary particulates were presumed. Therefore, it was considered that in the samples other than Mn the origins of water soluble and insoluble components are different each other from their behavior. The water-soluble part may be mostly ammonium salt (secondary particulate) from the measurement of NH 4 + . Furthermore, it became clear that the evolution of secondary particulate varies largely with season. Then, the variation with season was presumed by the main component analysis using the statistical software, SPSS adding to the correlation coefficient. This method has proved to be effective. (M.H.)

    A survey was conducted of the current status of energy supply/demand, future problems, goals of the energy policy, basic plan, and so forth, for the formulation of a new energy vision for the city. Concerning energy supply/demand, studies were made of each sector, area, and energy source. In the study of energy demand, it was discovered that, although the industrial sector in the coastal region remained important, the residential/commercial sector was gathering weight and that the city was serving as an energy supply base for the neighboring areas. In the study of new energy, it was found that the available amount of solar energy resources was enormous, that the Tama river fresh water and the Keihin canal seawater constituted a promising source of temperature difference energy, and that sewage energy, transformation station exhaust heat, LNG (liquefied natural gas) cold heat, and so forth, were also available as energy sources. Taken up for discussion as possible new energy introduction models were gas engine cogeneration, photovoltaic power generation, district heat supply utilizing temperature difference energy, and so forth.

Therefore, the management of side effects is essential for the longer period of continuous medication. Among the various side effects, hand–foot syndrome (HFS is the most common, occurring in 30%–50% of patients, and often results in discontinuation of the SOR medication. However, its mechanism has not been clarified, and no effective prevention method has been reported for the symptoms. Therefore, this study aimed to analyze its mechanism and to develop an effective prevention regimen for the symptoms. Materials and methods: To assess the mechanism of SOR-induced HFS, the peripheral blood flow in the hand and foot was carefully monitored by Doppler ultrasound, thermography, and laser speckle flowgraphy in the cases treated with SOR and its contribution was assessed. Then, the effect of dried-bonito broth (DBB, which was reported to improve peripheral blood flow, on the prevention of the symptom was

The technique is simple, however it is sometimes troublesome.Purpose: We describe a simple technique for hydrating the corneal stroma in cataract surgery using an irrigation port.Patients and methods: The technique began by pushing the irrigation port against the corneal stroma for a few seconds during phacoemulsification, which generated edema in the corneal incision that subsequently prevented leakage. This procedure is called the hydration using irrigation port (HYUIP technique. A total of 60 eyes were randomized and placed in two groups, 30 eyes underwent surgeries using the HYUIP technique (HYUIP group and 30 eyes underwent surgeries without the HYUIP technique (control. The three points evaluated during each surgery included 1 the occurrence of anterior chamber collapse during the pulling out of the I/A tip after inserting the intraocular lens, 2 the need for conventional hydration, and 3 watertight completion at the end stage of surgery.Results: The anterior chamber collapse and the need for conventional hydration were significantly smaller in the HYUIP group compared to the control group. Regarding the self-sealing completion, no significant difference was observed between the two groups.Conclusion: The HYUIP technique is an effective method for creating self-sealing wound. In addition, this technique helps to prevent anterior chamber collapse. Keywords: cataract surgery, hydration, irrigation and aspiration, phacoemulsification, wound, self-sealing

Magnetic nanoparticles of Fe3O4 (MgNPs-Fe3O4 can enhance the delivery and efficacy of anticancer drugs. We investigated the effects of MgNPs-Fe3O4 or DTX alone, and in combination with prostate cancer cell growth in vitro, as well as with the mechanism underlying the cytotoxic effects. MgNPs-Fe3O4 caused dose-dependent increases in reactive oxygen species levels in DU145, PC-3, and LNCaP cells; 8-hydroxydeoxyguanosine levels were also elevated. MgNPs-Fe3O4 alone reduced the viability of LNCaP and PC-3 cells; however, MgNPs-Fe3O4 enhanced the cytotoxic effect of a low dose of DTX in all three cell lines. MgNPs-Fe3O4 also augmented the percentage of DU145 cells undergoing apoptosis following treatment with low dose DTX. Expression of nuclear transcription factor κB in DU145 was not affected by MgNPs-Fe3O4 or DTX alone; however, combined treatment suppressed nuclear transcription factor κB expression. These findings offer the possibility that MgNPs-Fe3O4–low dose DTX combination therapy may be

We have previously studied plasma serotonin, which increases EE and exists in the small intestine, in individuals who ingested TAG and DAG oil, and found that DAG ingestion elevates plasma serotonin levels by about 50% compared with TAG ingestion. We studied the molecular mechanisms for DAG-mediated increase in serotonin and EE.Methods: We studied effects of 1-monoacylglycerol and 2-monoacylglycerol, distinct digestive products of DAG and TAG, respectively, on serotonin release from the Caco-2 cells (the human intestinal cell line, n = 8. Further, we studied effects of 1- and 2-monoacylglycerol, and serotonin on expression of mRNA associated with β-oxidation, FA metabolism, and thermogenesis, in the Caco-2 cells (n = 5.Results: 1-monoacylglycerol (100 µM 1-monooleyl glycerol [1-MOG] significantly increased serotonin release from the Caco-2 cells compared with 2-monoacylglycerol (100 µM 2-MOG by 36.6%. Expression of mRNA of acyl-CoA oxidase (ACO, fatty acid translocase (FAT, and uncoupling protein-2 (UCP-2 were significantly higher in 100 µM 1-MOG-treated Caco-2 cells than 100 µM 2-MOG-treated cells by 12.8%, 23.7%, and 35.1%, respectively. Further, expression of mRNA of ACO, medium-chain acyl-CoA dehydrogenase, FAT, and UCP-2 were significantly elevated in serotonin (400 nM-treated Caco-2 cells compared with cells incubated without serotonin by 28.7%, 30.1%, and 39.2%, respectively.Conclusions: Our

The aim of this study was to assess the correlation between interlobar synchrony in lung density and spirometric values in COPD patients and smokers, by measuring the continuous changes in lung density during respiration on the dynamic-ventilation CT. Materials and methods: Thirty-two smokers, including ten with COPD, underwent dynamic-ventilation CT during free breathing. CT data were continuously reconstructed every 0.5 sec. Mean lung density (MLD of the five lobes (right upper [RU], right middle [RM], right lower [RL], left upper [LU], and left lower [LL] was continuously measured by commercially available software using a fixed volume of volume of interest which was placed and tracked on a single designated point in each lobe. Concordance between the MLD time curves of six pairs of lung lobes (RU-RL, RU-RM, RM-RL, LU-LL, RU-LU, and RL-LL lobes was expressed by cross-correlation coefficients. The relationship between these cross-correlation coefficients and the forced expiratory volume in one second/forced vital capacity (FEV1.0/FVC values was assessed by Spearman rank correlation analysis. Results: In all six pairs of the pulmonary lobes, the cross-correlation coefficients of the two MLD curves were significantly positively correlated with FEV1.0/FVC (ρ =0.60–0.73, P<0.001.

The aim of this study was to compare the effects of HIIT using leg-cycling (LC and arm-cranking (AC ergometers with an HIIT program using only LC. Effects on aerobic capacity and skeletal muscle were analyzed. Twelve healthy male subjects were assigned into two groups. One performed LC-HIIT (n=7 and the other LC- and AC-HIIT (n=5 twice weekly for 16 weeks. The training programs consisted of eight to 12 sets of >90% VO2 (the oxygen uptake that can be utilized in one minute peak for 60 seconds with a 60-second active rest period. VO2 peak, watt peak, and heart rate were measured during an LC incremental exercise test. The cross-sectional area (CSA of trunk and thigh muscles as well as bone-free lean body mass were measured using magnetic resonance imaging and dual-energy X-ray absorptiometry. The watt peak increased from baseline in both the LC (23%±38%; P<0.05 and the LC–AC groups (11%±9%; P<0.05. The CSA of the quadriceps femoris muscles also increased from baseline in both the LC (11%±4%; P<0.05 and the LC–AC groups (5%±5%; P<0.05. In contrast, increases were observed in the CSA of

    1980-01-01

    Radiation doses and possible biological risks due to dental full mouth examination (adult: 10-film technique, child: 6-film technique) were evaluated based on preliminary experiments and statistical surveillance of patients' records. Dosimetrical studies were performed by using head and neck phantoms and a dental x-ray tube. Radiation doses were measured by x-ray films and thermoluminescence dosimeters. For the obtained doses of skin, eyes, thyroid gland and bone marrow, the biological risk of leukemia and thyroid cancer was discussed on the statistical basis of patients at Kanagawa Dental College Hospital. The major findings were as follows: The total number of patients who recieved full mouth x-ray examination at Kanagawa Dental College Hospital in 1978 was 1,099. The number of male patients was 382 (3,804 films) and that of female patients was 717 (7,138 films). In both sexes, the number of patients was the greatest in the group of 8 - 14 years of age. The collective doses of bone marrow due to full mouth 10-film examination performed at Kanagawa Dental College Hospital in 1978 were approximately 6.0 rad, which could induce leukemia with a probability of 1/8,000. The collective doses of thyroid gland were approximately 13 rad, which could induce lethal thyroid cancer with a probability of 1/15,000. The radiation dose due to the dental radiography for examination at Kanagawa Dental College Hospital was proved to be apparently below the level that could actually induce radiation injuries. But the collective radiation doses due to dental examination in Japan as a whole were approximately 8,000 times greater than that in Kanagawa Dental College Hospital. (J.P.N.)

    Full Text Available Whereas Vitruvius´ Firmitas –understood as a focus on organization that is fundamentally staticis almost universally considered to be a key strategy of architectural design, this paper attempts to outline an alternative conceptual framework in which the passing of time constitutes an additional parameter of spatial configuration. This approach is based on the notions of field, event and alloy, and points towards a range of design outcomes characterized by being in a permanent state of transformation. As a case study of this understanding of the design process, this paper puts forward an analysis of the Kanagawa Institute of Technology Workshop designed by Junya Ishigami.

    Airborne particulate matter was collected at the intersection of Industrial Road in Kawasaki-city, Kanagawa, Japan using a 12-stage low-pressure impactor. High concentrations of airborne particulate matter have been observed in this area. The collected samples were analyzed for 34 elements by instrumental neutron activation analysis (INAA), and data on the elemental concentrations were obtained. High concentrations of fine particles of As, Br, Sb, V, and Zn were observed. It was further observed that these fine particles were originated predominantly from the wear of tires and brakes, and not from automobile exhaust emissions. (author)

    A male Queensland koala (Phascolarctos cinereus adustus) at Kanazawa Zoological Gardens (Kanagawa, Japan) exhibited paralytic symptoms in the hind limbs. Computed tomography and magnetic resonance imaging revealed a mass on the left ventral side of the 11th to 13th thoracic vertebrae, and the presence of myelitis or edema in the spinal cord. The koala was under anesthesia during the examination and suddenly developed ventricular fibrillation and died. Necropsy revealed a firm flat ovoid hemorrhagic mass on the vertebrae. Following a microscopic examination including immunohistochemistry, the perivertebral mass was diagnosed as B cell lymphoma. Therefore, neoplastic cell infiltration into the spinal cord may cause paralytic symptoms in the hind limbs.

    2012-02-01

    Full Text Available Vibrio parahaemolyticus is a halophilic gram negative, motile, oxidase positive, straight or curved rod-shaped, facultative anaerobic bacteria that occur naturally in the marine environment. They form part of the indigenous microflora of aquatic habitats of various salinity and are the major causative agents for some of the most serious diseases in fish, shellfish and penacid shrimp. This human pathogen causes acute gastroenteritis characterized by diarrhea, vomiting and abdominal cramps through consumption of contaminated raw fish or shellfish. V. parahaemolyticus is the leading cause of gastroenteritis due to the consumption of seafood worldwide. The incidence of V. parahaemolyticus infection has been increasing in many parts of the world, due to the emergence of O3:K6 serotype carrying the tdh gene which is responsible for most outbreaks worldwide. The pathogenicity of this organism is closely correlated with the Kanagawa phenomenon (KP + due to production of Kanagawa hemolysin or the thermostable direct hemolysin (TDH. The TDH and TRH (TDH-related hemolysin encoded by tdh and trh genes are considered to be important virulence factors. [Vet. World 2012; 5(1.000: 48-63

    Service water, 100 liters each, was collected at an intake of a water-treatment plant and at a tap after water was left running for five minutes. Water, to which the carriers of strontium and cesium were added immediately after sampling, was vigorously stirred and filtered. The sample was then passed through a cation exchange column. After radiochemical separation, the precipitates were counted for the activity using a low-background beta counter, normally for 60 min. The measuring techniques are first described; i.e. the collection and pretreatment of samples, the preparation of samples for analysis, the separation of strontium-90 and cesium-137, and the counting. The measured results are given in a table for the following locations: source water - Tokyo, Osaka, Hokkaido, Kyoto, Kanagawa, Aichi, Fukuoka; tap water - Hokkaido, Akita, Fukushima, Tokyo, Fukui, Shizuoka, Shimane, Okayama, Fukuoka, Saga, Nagasaki, Kyoto, Wakayama, Okinawa, Hiroshima, Aomori, Yamagata, Ibaraki, Kanagawa, Niigata, Ishikawa, Nagano, Aichi, Osaka, Hyogo, Tottori, Yamaguchi, Ehime, Kochi, Kagoshima.

    Full Text Available Ten out of fifty fresh and refrigerated samples of shrimp (Litopenaeus vannamei collected from retailers in Natal (Rio Grande do Norte, Northeastern Brazil tested positive for Vibrio parahaemolyticus. The Kanagawa test and multiplex PCR assays were used to detect TDH and TRH hemolysins and the tdh, trh and tlh genes, respectively. All strains were Kanagawa-negative and tlh-positive. Antibiotic susceptibility testing was done for seven antibiotics by the agar diffusion technique. Five strains (50% presented multiple antibiotic resistance to ampicillin (90% and amikacin (60%, while two strains (20% displayed intermediate-level resistance to amikacin. All strains were sensitive to chloramphenicol. Intermediate-level susceptibility and/or resistance to other antibiotics ranged from 10 to 90%, with emphasis on the observed growing intermediate-level resistance to ciprofloxacin. Half our isolates yielded a multiple antibiotic resistance index above 0.2 (range: 0.14-0.29, indicating a considerable risk of propagation of antibiotic resistance throughout the food chain.

    Evaluations were given on spatial resolution and measurement time of an optical tomographic system by using the developed 64-channel time-resolved spectroscopy and an image reconstruction algorithm. With respect to the spatial resolution, the target value of 1 cm was verified from tomographic images of a phantom with a diameter of 10cm, simulating a neonate. The measurement time achieved 20 minutes, being one third of the target value. In installing the equipment at Hokkaido University, speeds of the optical switches and attenuators were increased to have reduced the measurement time to one minute. For installation at Kanagawa Rehabilitation Center, development has been made on a nano-second light pulser, whose average beam quantity has been increased to 40 times, and improvement has been given on the optical switches, the attenuators, and the indication software, by which the measurement time was decreased further by 30 seconds than that at Hokkaido University. In performing the clinical evaluation, the evaluation protocol resolved by the Experiment Evaluation Special Committee was submitted for deliberation at the Medical Welfare Device Clinical Evaluation Committee. Upon having been authorized by the Committee, the clinical evaluations were performed at Hokkaido University and the Kanagawa Rehabilitation Center. (NEDO)

    Following Aoki’s statistical mechanics methodology [Masanao Aoki, New Approaches to Macroeconomic Modeling, Cambridge University Press, 1996; Masanao Aoki, Modeling Aggregate Behaviour and Fluctuations in Economics, Cambridge University Press, 2002; Masanao Aoki, and Hiroshi Yoshikawa, Reconstructing Macroeconomics, Cambridge University Press, 2006], we provide some insights into the well-known works of [Bruce Greenwald, Joseph Stiglitz, Macroeconomic models with equity and credit rationing, in: R. Hubbard (Ed.), Information, Capital Markets and Investment, Chicago University Press, Chicago, 1990; Bruce Greenwald, Joseph Stiglitz, Financial markets imperfections and business cycles, Quarterly journal of Economics (1993)]. Specifically, we reach analytically a closed form solution of their models overcoming the aggregation problem. The key idea is to represent the economy as an evolving complex system, composed by heterogeneous interacting agents, that can be partitioned into a space of macroscopic states. This meso level of aggregation permits to adopt mean-field interaction modeling and master equation techniques.

  18. Statistics on the use of radiation in Japan. 1982 ed.

    International Nuclear Information System (INIS)

    1982-01-01

    In the recent several years, the establishments using radiation, i.e. radioisotopes and radiation generators, have continued to increase in number, and reached a total of 4,100 as of March, 1982. Such establishments are concentrated in major urban areas including Tokyo, Kanagawa, Osaka and Aichi, from which the utilization should spread across the country. The uses first started in the basic and applied studies in agriculture, sciences, medicine, etc., and are now extended to non-destructive testing, process measurement and therapies. Thus, the utilization of radiation has been increasingly diversified and complicated. The statistics thereon should contribute to both RI production and utilization and radiation injury prevention. The following data are given in tables: general aspects, the utilization of radiation by organizations (hospitals, educational institutions, research institutions, industries, etc.), the distribution of radioisotopes, the disposal of radioactive wastes, radiological protection supervisors and trainees.

    Full Text Available In the current study, a macroscopic lattice Boltzmann model for simulating the heat and moisture transport phenomenon in unsaturated porous media during the freezing process was proposed. The proposed model adopted percolation threshold to reproduce the extra resistance in frozen fringe during the freezing process. The freezing process in Kanagawa sandy loam soil was demonstrated by the proposed model. The numerical result showed good agreement with the experimental result. The proposed model also offered higher computational efficiency and better agreement with the experimental result than the existing numerical models. Lattice Boltzmann method is suitable for simulating complex heat and mass transfer process in porous media at macroscopic scale under proper dimensionless criterion, which makes it a potentially powerful tool for engineering application.

    Oyster and seawater samples were collected seasonally from May 1984 through April 1985 from shellfish-growing areas in Washington, California, Texas, Louisiana, Alabama, Florida, South Carolina, Virginia, and Rhode Island which had been designated as approved or prohibited by the National Shellfish Sanitation Program. Fecal coliforms counts, aerobic plate counts, and Vibrio parahaemolyticus densities were determined for the samples. Mean V. parahaemolyticus density was more than 100 times greater in oysters than in water, whereas density of fecal coliforms was approximately 10 times higher in oysters. Seasonal and geographical distributions of V. parahaemolyticus were related to water temperature, with highest densities in samples collected in the spring and the summer along the Gulf coast. The synthetic DNA probe for thermostable direct hemolysin hybridized with 2 of 50 isolates, 1 of which was positive by the Kanagawa test.

    This study explores the psychological effects that Japanese people experience when consuming their "Shikohin", such as alcohol, tea, coffee, and tobacco. We'conducted a cross-sectional study among 542 people, from 20-to 69-year-old; who regularly consumed any one of "Shikohin" in Tokyo, Kanagawa, Saitama, and Chiba. The participants responded to an anonymous questionnaire concerning the consumption patterns of their "Shikohin" and the psychological effects that they experienced in taking in their "Shikohin". Results obtained using the K-J methods showed three common psychological effects in each "Shikohin". These effects included an increase in relaxation response, the promotion of social relationships, and an increase in positive mood. Our findings suggest that Japanese people may get some common effects through consumption of different "Shikohin".

    The Intrinsically Safe and Economical Reactor (ISER) is designed based on the principle of a process inherent ultimate safe reactor, PIUS, a so-called inherently safe reactor (ISR). ISER has been developed joingly by the members of the Kanagawa Institute of Technology, the University of Tokyo, the Japan Atomic Energy Research Institute (JAERI) and several industrial firms in Japan. This paper describes the requirements for the next generation of power reactor, the safety design philosphy of ISR and ISER, the controllability of ISER and the results of analyses of some of the design-based accidents (DBA) of ISER, namely station blackout, accidents in which the pressurizer relief valve becomes jammed and stuck in open position and tube breaks in the steam generator. It is concluded that the ISER can ensure a wide range of contraollabitily and fuel integrity for all the analysed DBAs. (orig.)

    Full Text Available The ability to ascertain the extent of product sale fluctuations for each store and locality is indispensable to inventory management. This study analyzed POS data from 158 convenience stores in Kawasaki City, Kanagawa Prefecture, Japan and found a power scaling law between the mean and standard deviation of product sales quantities for several product categories. For the statistical domains of low sales quantities, the power index was 1/2; for large sales quantities, the power index was 1, so called Taylor's law holds. The value of sales quantities with changing power indixes differed according to product category. We derived a Poissonian compound distribution model taking into account fluctuations in customer numbers to show that the scaling law could be explained theoretically for most of items. We also examined why the scaling law did not hold in some exceptional cases.

    We reviewed growth and endocrine functions in 29 patients who underwent stem cell transplantation (SCT) at the Kanagawa Children's Medical Center and survived without disease for more than 1 year after their SCT. In our study, the more severe decrease of height standard deviation score (SDS) was observed in children who had undergone SCT at an earlier age, using total body irradiation (TBI). The risk factor of hypothyroidism after SCT was the cranial irradiation before SCT. Gonadal dysfunction occurred frequently in both boys and girls regardless of preparative regimen before SCT. It is important to observe carefully the effect of SCT on growth and endocrine function, and to consider whether the hormonal therapy is indicated. (author)

    The results of examination on the relationship between air pollution by lead in auto exhaust and lead content of teeth of schoolchildren living in highly polluted, moderately polluted, and nonpolluted areas in Kanagawa Prefecture in 1968 are reported. The specimens were milk teeth which have fallen out and teeth in caries which were pulled out. The 177 specimens were brushed well, washed with distilled water and dried to be wet-calcined. Because of no difference of lead content between boys and girls teeth, the examination was carried on combined specimens. The findings were: (1) lead content was significantly higher in teeth of children in heavily and moderately polluted areas than in those in nonpolluted areas; (2) the lead content by area and by age showed lower values in older children in highly and nonpolluted areas. In general, the lead content of teeth was higher in children living in more polluted areas suggesting the effect of environmental pollution.

Diet is an important factor that can be modified to prevent hypertension. According to the US Department of Health and Human Services, dietary patterns are defined as the quantities, proportions, and variety or combinations of different foods and beverages in diets and the frequency with which they are habitually consumed. In this review, the vegetarian dietary pattern is introduced with a focus on the effect on blood pressure (BP. Although the available evidence is limited, according to a previous meta-analysis of controlled trials, vegetarian dietary patterns significantly reduced systolic and diastolic BPs. One of the common features of a vegetarian diet is weight loss, which might, at least partially, explain the effect on BP. Other possible factors such as sodium, potassium, protein, amino acids, vitamin B-12, antioxidants, fiber, and the microbiome are introduced as possible mechanisms. Further studies are needed with non-Western populations to determine the most effective vegetarian dietary pattern and to explore the exact mechanisms by which these dietary patterns affect BP.

    Background Although the impacts of temperature on mortality and morbidity have been documented, few studies have investigated whether day-to-day temperature change and diurnal temperature range (DTR) are independent risk factors for out-of-hospital cardiac arrest (OHCA). Design This was a prospective, population-based, observational study. Methods We obtained all OHCA data from 2005-2013 from six major prefectures in Japan: Hokkaido, Tokyo, Kanagawa, Aichi, Kyoto, and Osaka. We used a quasi-Poisson regression analysis with a distributed-lag non-linear model to assess the associations of day-to-day temperature change and DTR with OHCA for each prefecture. Results In total, 271,698 OHCAs of presumed cardiac origin were reported during the study period. There was a significant increase in the risk of OHCA associated with cold temperature in five prefectures, with relative risks (RRs) ranging from 1.298 (95% confidence interval (CI) 1.022-1.649) in Hokkaido to 3.893 (95% CI 1.713-8.845) in Kyoto. DTR was adversely associated with OHCA on hot days in Aichi (RR 1.158; 95% CI 1.028-1.304) and on cold days in Tokyo (RR 1.030; 95% CI 1.000-1.060), Kanagawa (RR 1.042; 95% CI 1.005-1.082), Kyoto (RR 1.060; 95% CI 1.001-1.122), and Osaka (RR 1.050; 95% CI 1.014-1.088), whereas there was no significant association between day-to-day temperature change and OHCA. Conclusion We found that associations between day-to-day temperature change and DTR and OHCA were generally small compared with the association with mean temperature. Our findings suggest that preventative measures for temperature-related OHCA may be more effective when focused on mean temperature and DTR.

Therefore, we evaluated the bacteriological incidence in the bronchoalveolar lavage fluid (BALF of pneumonia patients using cultivation and a culture-independent molecular method. Japanese patients with community-acquired pneumonia (83 and healthcare-associated pneumonia (94 between April 2010 and February 2014 were evaluated. The BALF obtained from pneumonia lesions was evaluated by both cultivation and a molecular method. In the molecular method, ~600 base pairs of bacterial 16S ribosomal RNA genes in the BALF were amplified by polymerase chain reaction, and clone libraries were constructed. The nucleotide sequences of 96 randomly selected colonies were determined, and a homology search was performed to identify the bacterial species. A qualitative radiological evaluation of pulmonary emphysema based on chest computed tomography (CT images was performed using the Goddard classification. The severity of pulmonary emphysema based on the Goddard classification was none in 47.4% (84/177, mild in 36.2% (64/177, moderate in 10.2% (18/177, and severe in 6.2% (11/177. Using the culture-independent molecular method, Moraxella catarrhalis was significantly more frequently detected in moderate or severe emphysema patients than in patients with no or mild emphysematous changes.

Patients and methods: Secondary analysis was performed, using existing data obtained from April to November 2010, for patients with VLU. Thermographic images of wounds and their surrounding area were classified according to the periwound temperature pattern as "normal temperature" or "high temperature". These results were compared with the self-reported pain intensity assessed by the short-form McGill Pain Questionnaire. Cohen's kappa coefficients were used to evaluate the interrater reliability for temperature assessment, and Wilcoxon rank sum test was used to compare pain intensities between the two groups. Results: Among 39 thermographic examinations in eight patients, 22 were classified into the high-temperature group and 17 into the normal-temperature group. Kappa coefficients for the temperature classification were 0.90 between the wound, ostomy, and continence nurse and a wound care specialist, and 0.90 between the wound, ostomy, and continence nurse and a graduate student. The pain rating index (Z=−2.981, P=0.003, sensory pain (Z=−3.083, P=0.002, affective pain (Z=−2.764, P=0.006, and present pain intensity (Z=−2.639, P=0.006 ratings were significantly higher in the high-temperature group than in the normal-temperature group, but the visual analog scale (Z=−0.632, P=0.527 was not significantly different between the two groups.

The themes were 'a sustainable energy strategy for the nineties', 'industrial structure change and energy problem', and 'new energy and the global environment'. The panelists were from Sweden, France, Thailand, U.S.A., and Japan. The main subject was energy security, in which discussion was held on the uneven distribution of oil resources in the Middle East and political instability in the region and on counter measures against global warming problem. The discussion on the latter subject showed that a limitation exists in the total consumption of fossil fuel in the world, and that energy policies were meaningless unless they were on a global scale. As the concrete measures, energy conservation technologies and regenerative energy utilization technologies need to be developed and spread, for which emphasized was the spread on a global scale, namely, the necessity of international cooperation and an international propulsion system.

He was treated with one cycle of high-dose dexamethasone. After three cycles of bortezomib, the patient exhibited slow elevations in the free light-chain levels and developed a significant new increase of serum M protein. Bone marrow cytogenetic analysis revealed a complex karyotype characteristic of malignant plasma cells. To better understand the molecular pathogenesis of this patient, we sequenced for mutations in the entire coding regions of 409 cancer-related genes using a semiconductor-based sequencing platform. Sequencing analysis revealed eight nonsynonymous somatic mutations in addition to several copy number variants, including CCND1 and RB1. These alterations may play roles in the pathobiology of this disease. This targeted next-generation sequencing can allow for the prediction of drug resistance and facilitate improvements in the treatment of MM patients.

    Full Text Available Sōgetsu Art Center, one of the most important venues for the avant-garde in 1960s Japan, could be defined as an artistic “experimental sandpit”. Its activities brought new musical expressions to the world of Japanese art, and lead to the independent film production. Japanese artists could play in this sandpit with a group of interdisciplinary peers and thus search for their most suitable artistic styles. Good examples are film director Hiroshi Teshigahara (1927–2001, playwright Kōbō Abe (1924–1993 and musician Tōru Takemitsu (1930–1996. The article gives an insight into the artistic associations and events, which took place under the roof of the Sōgetsu Art Center in the period from September 1958 to March 1971. The emphasis will be put on the main associations; activities related to the fields of jazz music, contemporary music, experimental film and animation. We will look for the common ground among these, and note the innovations which were brought about by the main participants at the Center in the fields of music and film.

'Polymeric nano-soft-materials' are novel outcomes based on a recent innovative evolution in polymer science, i.e. precision polymer synthesis, self-assembling and functionalization of multi-component systems. The materials are expected to exhibit specific functions and unique properties due to their hierarchic morphologies brought either by naturally-generated ordering or by artificial manipulation of the systems, e.g., crystallization and phase-separation. The emerging precision synthesis has brought out new types of polymers with well-controlled primary structures. Furthermore, the surface and interface of the material are recognized to play an important role in the outstanding mechanical, electrical and optical properties, which are required for medical and engineering applications. In order to understand structure-property relationships in the nano-soft-materials, it is indispensable to develop novel characterization techniques. Symposium Y

As an anaplastic lymphoma kinase (ALK gene translocation was identified, the therapy was changed to crizotinib. However, the patient’s blood creatinine level increased, and her physical status worsened. Alectinib also induced exacerbation of renal dysfunction but was controlled by dose reduction of 140 mg twice daily for 2 weeks treatment and 2 weeks break were repeated, and exhibited a partial response for 16 months. Here, we describe the case in which alectinib treatment had beneficial clinical effects on ALK-positive lung adenocarcinoma, which controlled the adverse renal effects by dose reduction and drug breaks.

In this study, we performed complementary DNA cloning for Cdkal1 in the cat and dog and characterized the tissue expression profiles of its messenger RNA. Cat and dog Cdkal1 complementary DNA encoded 576 and 578 amino acids, showing very high sequence homology to mammalian CDKAL1 (>88.4%. Real-time polymerase chain reaction analyses revealed that Cdkal1 messenger RNA is highly expressed in smooth muscle and that tissue distribution of Cdkal1 is similar in cats and dogs. Genotyping analysis of single-nucleotide polymorphism for cat Cdkal1 revealed that obese cats had different tendencies from normal cats. These findings suggest that the cat and dog Cdkal1 gene is highly conserved among mammals and that cat Cdkal1 may be a candidate marker for genetic diagnosis of obesity.Keywords: cat, dog, Cdkal1, obese, cDNA cloning, Q-PCR

  3. Medical aspects of boron-slow neutron capture therapy

    Earlier radiations of patients with cerebral tumors disclosed the need: (1) to find a carrier of the boron compound which would leave the blood and concentrate in the tumor, (2) to use a more penetrating neutron beam, and (3) to develop a much faster method for assaying boron in blood and tissue. To some extent number1 has been accomplished in the form of Na 2 B 12 H 11 SH, number2 has yet to be achieved, and number3 has been solved by the measurement of the 478-keV gamma ray when the 10 B atom disintegrates following its capture of a slow neutron. The hitherto unreported data in this paper describe through the courtesy of Professor Hiroshi Hatanaka his studies on the pharmacokinetics and quality control of Na 2 B 12 H 11 SH based on 96 boron infusions in 86 patients. Simultaneous blood and tumor data are plotted here for 30 patients with glioblastomas (Grade III-IV gliomas), illustrating remarkable variability. Detailed autopsy findings on 18 patients with BNCT showed radiation injury in only 1. Clinical results in 12 of the most favorably situated glioblastomas reveal that 5 are still alive with a 5-year survival rate of 58% and the excellent Karnofsky performance rating of 87%. For the first time evidence is presented that slow-growing astrocytomas may benefit from BNCT. 10 references, 8 figures, 5 tables

    This experiment was carried out in Biological Control of Domestic Fly 'Eduardo Hiroshi Mizumoto' Laboratory at Entomology and Acarology Department (LEA/ESALQ/USP) and in Food Irradiation and Radioentomology Laboratory (LIARE/CENA/USP). The gamma radiation source used was a Co-60 irradiator model Gammabeam-650 of the Atomic Energy of Canada Ltd. whose activity in the beginning of the experiments was 9.8x10{sup 13} Bq. (2,644 Ci). The lots of pupae of Musca domestic L., 1758 and the parasitoid Spalangia endius Walker, 1839 had been kept in acclimatized room with 25 ± 2 deg C of temperature and 70 ± 5% of relative humidity. This experiment was designed to investigate if the non-viabilization M. domestic pupae, using gamma radiation, could build up the acceptability period as host of the pupal parasitoid S. endius. At these age intervals, the dose to prevent adult emergence was 25, 220, 360 and 520 Gy respectively. The 1, 2, 3 and 4 days old pupae were irradiated (dose rate: 1,510 Gy/hr) and exposed to the parasitoid S. endius at a proportion of one female parasitoid to five housefly pupae, during different periods after the irradiation. The results allow us to conclude that irradiation increase the acceptability period of the housefly pupae by the parasitoid. The best age to irradiate the housefly pupae was one day. (author)

    Two lectures were given by Christopher Flavin (vice president for Research, Worldwatch Institute Inc.) and Hiroshi Takeuchi (chairman, LTCB Consulting and Research Institute Inc.), and a panel discussion was held by five panelists with Toyoaki Ikuta (The Institute of Energy Economics, Japan) as the coordinator. The themes were 'a sustainable energy strategy for the nineties', 'industrial structure change and energy problem', and 'new energy and the global environment'. The panelists were from Sweden, France, Thailand, U.S.A., and Japan. The main subject was energy security, in which discussion was held on the uneven distribution of oil resources in the Middle East and political instability in the region and on counter measures against global warming problem. The discussion on the latter subject showed that a limitation exists in the total consumption of fossil fuel in the world, and that energy policies were meaningless unless they were on a global scale. As the concrete measures, energy conservation technologies and regenerative energy utilization technologies need to be developed and spread, for which emphasized was the spread on a global scale, namely, the necessity of international cooperation and an international propulsion system.

  8. The road to miniaturization

    2006-01-01

    Silicon microelectronics has revolutionized the way we live, but how long can the relentless down sizing of devices continue? Hei Wong and Hiroshi Iwai describe the challenges facing the semiconductor industry today. For the last four decades the miniaturization of the microchip has been the driving force behind developments in all kinds of technology, from home entertainment to space exploration. At the heart of this revolution lies the metal-oxide-semiconductor (MOS) transistor, which has evolved in two ways. First, it has become smaller, with the latest devices measuring a thousandth of their original size. Second, the number of transistors that can be interconnected on a single chip has risen from a few tens to hundreds of millions. The density of microchips has followed an exponential trend that was famously identified by Gordon Moore of Intel in 1965. Moore predicted that the number of components that could be crammed into an integrated circuit would double every two years for the foreseeable future. In fact, he slightly underestimated the trend, because the average number has actually doubled every 18 months. The question keeping chip manufacturers awake in 2005 is how long this exponential growth can continue. (U.K.)

A recent study reported that the administration of astaxanthin induced a significant reduction in blood pressure and delayed the incidence of stroke in stroke-prone spontaneously hypertensive rats, suggesting that astaxanthin also has antihypertensive effect. In a study using aortic rings of spontaneously hypertensive rats, astaxanthin induced a significant reduction of the contractile responses of the aorta to α-adrenergic receptor agonist and angiotensin II, which may contribute to the antihypertensive effect of astaxanthin. In a histopathological study, astaxanthin decreased coronary artery wall thickness compared with the control, indicating the possibility that astaxanthin ameliorates hypertension-induced vascular remodeling. Astaxanthin has anti-inflammatory, antidiabetic, antihypertensive, and antioxidative activities; therefore, we should perform further studies to elucidate an antiatherogenic effect of astaxanthin.Keywords: astaxanthin, antioxidant, antihypertensive effect, atherosclerosis

    2017-10-01

    O-mannosyl glycans have been found in a limited number of glycoproteins of the brain, nerves, and skeletal muscles, particularly in α-dystroglycan (α-DG). Defects in O-mannosyl glycan on α-DG are the primary cause of a group of congenital muscular dystrophies, which are collectively termed α-dystroglycanopathy. Recent studies have revealed various O-mannosyl glycan structures, which can be classified as core M1, core M2, and core M3 glycans. Although many dystroglycanopathy genes are involved in core M3 processing, the structure and biosynthesis of core M3 glycan remains only partially understood. This review presents recent findings about the structure, biosynthesis, and pathology of O-mannosyl glycans. Recent studies have revealed that the entire structure of core M3 glycan, including ribitol-5-phosphate, is a novel structure in mammals; its unique biosynthetic pathway has been elucidated by the identification of new causative genes for α-dystroglycanopathies and their functions. O-mannosyl glycan has a novel, unique structure that is important for the maintenance of brain and muscle functions. These findings have opened up a new field in glycoscience. These studies will further contribute to the understanding of the pathomechanism of α-dystroglycanopathy and the development of glycotherapeutics.

    To determine the prevalence and effect of dietary habits on functional constipation in preschool and early elementary school children in Japan. A total of 3595 children aged 3 to 8 years from 28 nursery schools and 22 elementary schools in Yokohama City, Kanagawa Prefecture, Japan, were evaluated. The subjects were divided into a functional constipation group and a nonfunctional constipation group according to the Rome III criteria. Dietary intake data were collected using a brief-type, self-administered, diet-history questionnaire validated for Japanese preschool-aged children. Of the 3595 subjects evaluated, 718 (20.0%) had functional constipation. The association between functional constipation and gender was not statistically significant ( p = 0.617). A decrease in bowel frequency was observed in 15.9% of those with functional constipation. There was no significant difference in the proportion of participants in the constipation group by age ( p = 0.112). Binomial logistic regression analysis indicated that only fat per 100 kcal positively correlated with functional constipation [odds ratio = 1.216, 95% confidence interval: 1.0476-1.412]. Functional constipation is common among children in preschool and early elementary school in urban areas of Japan. Parents should pay attention to constipation-related symptoms other than defecation frequency. A high-fat diet should be avoided to prevent functional constipation.

    The decline of Japanese cedar occurred in old trees, of which the growth of height stopped, and it started from the withering of the upper layer of tree top. Usually the decrease of leaf number just under the tip of tree top is conspicuous, and soon, withering spreads to lower part. The decline is limited to the plain area of Kanto, and the Japanese cedar forests in the plain area are mostly the isolated forests in mansions, shrines and temples. The decline of Japanese cedar forests like these has begun in the latter half of 1960s, and it has become difficult to find Japanese cedar trees. According to the fact finding survey by Environment Agency and General Forest Research Institute, the decline spread radially in the plain area of low elevation, and according to directions, the state of spread is different. The decline occurred below the elevation of 100 m in the case of Tochigi, Ibaraki and Chiba, but in Gunma, Saitama, Kanagawa and western Tokyo, it spread to the places exceeding 100 m. The zone of serious degree of the decline spread to north western and western directions. The progress of the decline of Japanese cedar trees, the change of weather, and the state of atmospheric pollution are reported. (K.I.)

    The method of prediction of earthquakes by the change of concentration of Rn in groundwater was developed by U.S.S.R. and People's Republic of China, and was not known clearly. Since 1975, the research works on this subject were commenced by University of Tokyo, Geological Survey of Agency of Industrial Science and Technology and Tokyo Metropolitan Isotopic Research Center. Along with the development of an automatic continuous measuring apparatus with high reliability, the systems for the measurement of the Rn concentration in groundwater were established. At the time of the earthquake off Izu-Oshima on January 14, 1978, clear precursor was found in an artesian flowing well in Nakaizu 0f Izu Peninsula, and the unusual phenomena which seemed be the precursor of an earthquake were recognized in other districts of Izu and Tokai. On August 8, 1983, an earthquake of magnitude 6 occurred in the boundary region of Yamanashi and Kanagawa Prefectures. Preceding the earthquake, the unusual change of the concentration of Rn was recognized at several observation wells in Tokyo, and the unusual change was observed after the earthquake also. The possibility that the unusual change of the Rn concentration in groundwater is the precursor of earthquakes is high, and this phenomenon is expected to make contribution for the prediction of earthquakes, though there remain many problems to be solved. Further works are scheduled to establish the practical method of predicting earthquakes. (Isimitsu, A.)

When the state of forest areas is observed, evergreen broadleaf tree forests are in coastal areas and to the inland of 700 - 800 m elevation. Deciduous broadleaf tree forests are in the mountains exceeding 700 - 800 m. Further, fir and Japanese hemlock trees distribute in the area where both forests adjoin. At present, from terraces and hills to mountains, the plantations of Japanese cedar, Hinoki cypress and pine trees and the secondary forests of oak trees are seen. The decline of Japanese cedar trees in this Prefecture was first seen around 1960, and it was investigated in 1972 by dividing the tree form into five steps corresponding to the degree of decline. The progress of the decline, and the outline of fir tree forest in Oyama and its decline are reported. The secular change of growth ring width is utilized as the recorder of environmental change in the past such as weather, natural calamity and atmospheric pollution. The analysis of the course of decline using growth rings was carried out. The relation of the decline of forests to atmospheric pollution, and the decline of Japanese beech and fir trees in Tanzawa mountains are reported. (K.I.)

    Frequent outbreaks of Sarcoptes scabiei infestation in raccoon dogs (Nyctereutes procyonoides) have been reported in Japan. Although many raccoon dogs are brought to Kanazawa Zoological Garden (Yokohama, Kanagawa, Japan) because of S. scabiei infestation and debilitation, some of them die of asthenia. The clinical status of severely debilitated raccoon dogs must be determined to save their lives. In this study, we compared hematological and serum biochemical values between severely debilitated and nondebilitated raccoon dogs infested with S. scabiei. The total protein, albumin, glucose, and calcium values of debilitated raccoon dogs were significantly lower than those of nondebilitated raccoon dogs. On the other hand, debilitated raccoon dogs had significantly higher aspartate aminotransferase, total bilirubin, blood urea nitrogen, sodium, chloride, and phosphorus values than did nondebilitated raccoon dogs. The increase in the blood urea nitrogen value was particularly dramatic. The present study revealed that debilitated raccoon dogs infested with S. scabiei exhibited abnormal hematological values compared with nondebilitated raccoon dogs infested with S. scabiei. Clinically, the raccoon dogs developed malnutrition and sepsis if the mange infestation was untreated. Moreover, dehydration associated with appetite loss may have resulted in insufficient renal perfusion. These findings suggest that chronic S. scabiei infestations debilitated the raccoon dogs and resulted in physiological changes that were detected with hematological and serum biochemical tests.

    Sarcoptes scabiei infestation was diagnosed in three freshly dead free-ranging raccoon dogs (Nyctereutes procyonoides) in Kanagawa Prefecture, Japan. The dogs presented with an alopecic pruritic skin disease, with signs of alopecia on the ears, muzzle, around the eyes, elbow, thigh and the neck, and hyperpigmented and crusted skin lesions, which had a severe malodour. Skin scrapings revealed the presence of the mite Sarcoptes scabiei. Histopathology of lesions demonstrated marked acanthosis, hyperkeratosis, parakeratosis and fungal elements, which were subsequently identified as Acremonium sp., Alternaria sp. and an unknown fungus. Mite segments were located mainly in the stratum corneum and also in the stratum granulosum. Tunnels could be observed in the hyperkeratotic stratum corneum. Scanning electron microscopy (SEM) revealed the tortoise-like Sarcoptes scabiei with four long bristles, suckers and blade-like claws on legs 1 and 2, cuticular spines, prominent body striations and a terminal anus. SEM also revealed an adult female mite digging a tunnel with the head wedged into the very end of the closed burrow. Tunnels filled with eggshells, corneocyte debris and faecal pellets were also observed.

    Iodine is one of the important elements in the environmental and agricultural sciences. It is requested to elucidate the long-term behavior of iodine in the atmosphere - soil·plant - soil water system. We developed the new tracer method, in which iodine released into the atmosphere from the stack of iodine manufacturing plant in Chiba prefecture was used as the activable tracer. Using this method, we traced the direct deposition of iodine in atmosphere onto the plant tops and the penetration of fallout iodine into soil in an open air over a long period. A quantitative evaluation of recharge function of water resources in agricultural and forest lands of Japan was eagerly requested from the nation. For it, we developed the new Br - tracer method combined with the soil water sampling system with the alumina porous ceramic cup. This tracer method was successfully applied to the agricultural and forest land in the catchment area of Sakawa river in Kanagawa prefecture. And the infiltration rate of the rain water and irrigation water, from the soil surface to the dept of 3m of the soil horizon in the forest land, tea garden and paddy field was quantitatively measured during two years.

    Influenza C is usually considered a minor cause of respiratory illness in humans with many infections being asymptomatic or clinically mild. Large outbreaks can occur periodically resulting in significant morbidity. This study aimed at analyzing the available influenza C clinical samples from two widely separated states of Australia, collected over a 7-year period and to compare them with influenza C viruses detected in other parts of the world in recent years. Between 2008 and 2014, 86 respiratory samples that were influenza C positive were collected from subjects with influenza-like illness living in the states of Victoria and Western Australia. A battery of other respiratory viruses were also tested for in these influenza C-positive samples. Virus isolation was attempted on all of these clinical samples, and gene sequencing was performed on all influenza C-positive cultures. Detections of influenza C in respiratory samples were sporadic in most years studied, but higher rates of infection occurred in 2012 and 2014. Many of the patients with influenza C had coinfections with other respiratory pathogens. Phylogenetic analysis of the full-length hemagglutinin-esterase-fusion (HE) gene found that most of the viruses grouped in the C/Sao Paulo/378/82 clade with the remainder grouping in the C/Kanagawa/1/76 clade. © 2016 The Authors.

    The Great East Japan Earthquake on 11 March 2011 caused major damage in northeastern Japan. The Kanto region experienced a massive electrical power shortage in the summer of 2011. A questionnaire was submitted to 354 hemodialysis clinics in Kanagawa prefecture and the Tokyo metropolitan area, excluding isolated islands, and 176 responses were analyzed (49.7%). The questions included evaluation of the availability of a private electricity generator, countermeasures in case of a planned outage, awareness of saving electricity, and improvement of safety of medical devices or electrical facilities after the earthquake. Only 12% of the clinics had private electricity generators and many clinics had no plans to introduce this facility. However, 96% of the clinics had established countermeasures to deal with a planned outage. Many clinics planned to provide dialysis on a different day or at a different time. All clinics had tried hard to establish procedures to save electricity in the summer of 2011, and 84% of the clinics had reconsidered and improved the safety of medical devices or electricity facilities after the earthquake. These results show that the awareness of crisis management was greatly improved in the wake of the earthquake. © 2012 The Authors.

    The survey/research project is implemented for establishing environment-compatible energy systems in urban areas by constructing wide-area heat supply networks to exchange energy among cities. This project studies, taking Kanagawa Pref. as the model area, distributions of unutilized energy sources, and possibilities of their utilization for heat supply. There are large quantities of unutilized energy, including waste heat from power plants, general works and cleaning works, and low-temperature waste heat from, e.g., sewage and pumping systems. The district air conditioning promotion areas are selected from those consuming large quantities of heat energy in the prefecture, and their characteristics are grasped. The effects of the networks on total energy consumption of the entire prefecture are estimated for the cases of introducing the district air conditioning systems or wide-area heat supply networks in these selected areas. Introduction of optimum advanced heat utilization systems in stereotyped areas is also considered, in order to predict the effects of introduction of wide-area heat supply networks. (NEDO)

    Since 2003, India has had a well-established influenza surveillance network, though Influenza C virus was not the focus of study. We therefore retrospectively analyzed clinical samples from Pune, western India collected during January 2009 to August 2015, by real-time RT-PCR. Three of 2530 samples of patients with influenza-like illness (ILI) or severe acute respiratory illness (SARI) showed positivity for Influenza C virus infection, while 105 and 31 samples were positive for Influenza A and B viruses respectively. Influenza C viruses were successfully isolated using the embryonated egg system and whole genomes were sequenced and analyzed phylogenetically. HE gene-based phylogeny showed that two viruses C/India/P119564/2011 and C/India P121719/2012 clustered with the C/Sao Paulo/378/82 (SP82) lineage, whereas C/India/P135047/2013 clustered with the C/Kanagawa/1/76 (KA76) lineage. The internal gene of these viruses grouped in two lineages. The PB1, PB2, M and NS genes of the study viruses grouped with C/Yamagata/26/81 (YA81), while the P3 (PA) and NP genes grouped with C/Mississippi/80 (MS80). Bayesian clock studies conclude that the Indian strains may have emerged through multiple reassortment events. Copyright © 2017 Elsevier B.V. All rights reserved.

    The solar car race which technical high school students can join in was determined to be held at Ogata village, Akita prefecture. To join in the solar bicycle race, the author working in Ofuna technical high school called on 3 schools of Yokosuka, Fujisawa and Kanagawa technical high schools which joined in World Solar-Car Rally in Akita (WSR) in 1997, before fabrication of a racing bicycle. This paper describes the survey results at the above technical high schools, and the spirit as the teacher of Ofuna technical high school on joining in the race and fabrication of the solar bicycle, and the past, current and future situations. Club activities of high school students incline too toward sports such as soccer, baseball, volleyball and rugby, and are apt to keep honest cultural events and technical events at a distance. The author says that the challenge spirit to the solar car race using environment-friendly solar energy by both dedicated teachers and students of technical high schools summoned up the author`s courage. 15 figs.

    The purpose of the project in FY 1998 is 'Experimental verification for EV spread promotion.' Two of a 3-month experiment were conducted in Yokohama MM21 area (Yokohama, Kanagawa) and in Tama Newtown (Inage, Tokyo) using a total of 100 (50 each) small EVs. The development was aimed at of an urban type rental-car system in Yokohama and of a car-sharing type second-car system for residential in Inage. As to these responses to ITS technology, the basic vehicle operation system was made common in both areas, and the daily use system was made a regional system considered of purposes of use, regional characteristics, etc. The experimental verification was worked on as almost expected in terms of the vehicle management, monitor assessment, responses from persons concerned in both areas. Therefore, it is said that the R and D have almost reached a point where there can be seen a possibility of system commercialization. Through the experimental verification, the development was able to be smoothly promoted of the basic technology and element technology which are thought to be needed for the commercialization of EV. From the experience of this experimental verification, it is judged that it is desirable to tackle the commercialization by a membership system when the commercialization of EV joint use system is planned in future.

    The International Symposium on Radiation Education, which commemorates the centenary of the discovery of radium by the Curies, was held on December 11-14, 1998 in Kanagawa, Japan. At present, radiation and radioactivity are not indispensable in medical diagnosis and treatment, but also are widely used in scientific research and industrial activities. Nuclear power generation is also playing an important role in saving nonrenewable natural energy resources, and without producing the potentially hazardous carbon dioxide. However, a majority of people has a insufficient knowledge or information about radiation and radioactivity. The symposium intended to generalize the scientific knowledge about radiation and radioactivity and also about various aspects of risks associated with the life in the civilized society, by discussing how to improve education in general and young generations at schools in particular, and by exchanging the newest scientific information relevant to the education. The symposium consisted of 5 sessions with 61 submitted papers, and involved about 170 participants from Australia, Bangladesh, France, Germany, Hungary, Indonesia, Korea, Philippine, Pakistan, Thailand, Turkey, UK and USA.

    The number of the business establishments which utilize radiation with radioisotopes and radiation generators has continued to increase, and as of the end of March, 1989, it exceeded 4700. As to the state of utilization classified by districts, the use concentrates in large urban districts of Tokyo, Osaka, Kanagawa and Aichi, and the field of application spread to many fields of industries, agriculture, medical treatment and others. Recently, the utilization of radiation has become to be very highly advanced and diversified such as the medical diagnosis and treatment and the application to advanced technology using radiation generators. Now, the utilization of radiation is indispensable for national life and economical activities, but also the prevention of injury and the securing of safety are important. It is necessary to clarify the latest state of radiation utilization in Japan for the promotion of the production and utilization of radioisotopes and the prevention of radiation injury. In this book, the number of the business establishments using radiation and the state of utilization in medical, education and research, private enterprises and other fields, the state of distribution of radioisotopes, waste treatment, and radiation-related technicians are reported.

    Birth defects monitoring system is one of the most effective strategies to prevent birth defects mainly caused by environmental factors. Six different monitoring systems are working in Japan. Three of them are population-based and the other three hospital-based, both are widely scattered in Japan. Basic methodological designs of all birth defects monitoring systems are same. Therefore, the combination of them seems to be ideal. Total number of births surveyed in all systems are 283,000 annually. Each system has already accumulated relevant baseline data. Birth defects monitoring has another function to test the safety of widely exposed factors such as smoking, alcohol, low dose radiations, etc. Maternal smoking has some adverse effects on morphogenesis of the fetus. However, low dose radiations during or before pregnancy have no significant teratogenic effects on the fetus. The genetic effects of the Chernobyl nuclear power plant accident was studied. The annual effective dose equivalent to Japanese population due to radioactive fallout from the accident was assessed to be 5 μSv/y. No measurable mutagenic effects were recognized in Kanagawa by the analysis of three sentinel anomalies. (author)

    The needle-type leaves of Japanese black pine trees (hereafter abbreviated as pine needles) have been used as an effective bio-monitor of ambient air pollution. Miyata Laboratory of Setsunan University has reported that the pine needles accumulate PCDDs and PCDFs (hereafter abbreviated as D/F) through photosynthesis and respiration during their lifetime. On the basis of this study, we have revealed the correlation between ambient air and pine needle concentrations to be estimated at or near 1:10 by analyzing long term continuous ambient dioxin monitoring data and that of pine needles sampled from the same area as ambient air in the Kanagawa Prefecture in 1999. Since then, the citizen groups of each local area all over Japan have started monitoring the ambient air dioxin concentration levels by using pine needles. Samples analyzed during these 5 years totaled more than 650 throughout Japan. The results of these citizen participatory environmental monitoring activities are the tremendous effects achieved in reducing the dioxin levels. This occurs through observation of the dioxin emission sources such as Municipal Solid Waste Incineration Plants as well as the Industrial Waste Incineration plants, which exist in numbers exceeding several thousands in Japan. This short paper will present the results of 56 municipalities of western Japan where ambient air dioxin levels have improved steadily against local averages during these 5 years.

    Prevention is better than cure. Public health plays an important role in promoting prevent medicine. To obtain the abilities to provide appropriate nursing services, learning public health is necessary for students who want to become registered nurses. When teachers teach public health to nursing students, it is important to motivate them to learn it. Therefore, we investigated the reasons for the lack of motivation to learn public health by conducting a questionnaire survey. The subjects were female nursing students in 29 vocational schools in Kanagawa and Chiba prefectures of Japan that allow graduation after a 3-year study period. We asked the students whether or not they had completed the subject of public health and analyzed those students who answered affirmatively. We analyzed 1,553 respondents whose average age was 22.6 ± 5.2 years (range, 18 to 45). Using factor analysis, we discovered the 5 reasons that lead to the lack of nursing students' motivation to learn public health: "Difficulties acquiring knowledge of public health," "Inappropriate attitudes of public health teachers," "Thinking lightly about the national examination in the field of public health," "Lack of understanding the importance of learning public health," and "Future plans that do not specialize in public health." Using multiple linear regression analysis, these 5 reasons were significant predictors for the lack of students' motivation. Older students also had significantly less motivation to learn public health than did younger students. When teachers instruct their students, they should teach public health better with the present knowledge.

  18. Two types of nonlinear wave equations for diffractive beams in bubbly liquids with nonuniform bubble number density.

    2015-05-01

    This paper theoretically treats the weakly nonlinear propagation of diffracted sound beams in nonuniform bubbly liquids. The spatial distribution of the number density of the bubbles, initially in a quiescent state, is assumed to be a slowly varying function of the spatial coordinates; the amplitude of variation is assumed to be small compared to the mean number density. A previous derivation method of nonlinear wave equations for plane progressive waves in uniform bubbly liquids [Kanagawa, Yano, Watanabe, and Fujikawa (2010). J. Fluid Sci. Technol. 5(3), 351-369] is extended to handle quasi-plane beams in weakly nonuniform bubbly liquids. The diffraction effect is incorporated by adding a relation that scales the circular sound source diameter to the wavelength into the original set of scaling relations composed of nondimensional physical parameters. A set of basic equations for bubbly flows is composed of the averaged equations of mass and momentum, the Keller equation for bubble wall, and supplementary equations. As a result, two types of evolution equations, a nonlinear Schrödinger equation including dissipation, diffraction, and nonuniform effects for high-frequency short-wavelength case, and a Khokhlov-Zabolotskaya-Kuznetsov equation including dispersion and nonuniform effects for low-frequency long-wavelength case, are derived from the basic set.

    To evaluate a fully automated processing system (TACAS™ Pro) for liquid-based procedures (LBPs). Materials were 3,483 and additionally 502 specimens that were taken at Kanagawa Health Service Association. Specimens obtained with a Cervex-Brush® were first smeared to glass slides using one side of the brush and then processed to TACAS Pro. (1) The microscopy watching time per normal case was 3.65 ± 0.85 min in the conventional procedure, whereas in the LBP it was 1.95 ± 0.60 min, and the latter reduced workload to 53%. (2) The handling time of TACAS Pro per day was 2 h and 25.8 min. The workload at a laboratory offset it and revealed the work saving to be 63.8%. (3) Unsatisfactory rates were 0% in the conventional procedure, whereas in the LBP it was 1.88% at first. The latter rate decreased to 0.5% after system improvement. (4) Specimens which may disturb microscopy analysis were found in 1.06%, including 3 cases of possible carry-over of cells to the following slides. An additional study with the revised system confirmed no carry-over. (5) Incidences of abnormal cytology were consistent between the two methods. The revised automated processing system TACAS Pro is a feasible and useful LBP and reduces the workload of cytology laboratories. © 2015 S. Karger AG, Basel.

    Full Text Available In our previous study, we demonstrated the propagation of mouse-passaged scrapie isolates with long incubation periods (L-type derived from natural Japanese sheep scrapie cases in murine hypothalamic GT1-7 cells, along with disease-associated prion protein (PrPSc accumulation. We here analyzed the susceptibility of GT1-7 cells to scrapie prions by exposure to infected mouse brains at different passages, following interspecies transmission. Wild-type mice challenged with a natural sheep scrapie case (Kanagawa exhibited heterogeneity of transmitted scrapie prions in early passages, and this mixed population converged upon one with a short incubation period (S-type following subsequent passages. However, when GT1-7 cells were challenged with these heterologous samples, L-type prions became dominant. This study demonstrated that the susceptibility of GT1-7 cells to L-type prions was at least 105 times higher than that to S-type prions and that L-type prion-specific biological characteristics remained unchanged after serial passages in GT1-7 cells. This suggests that a GT1-7 cell culture model would be more useful for the economical and stable amplification of L-type prions at the laboratory level. Furthermore, this cell culture model might be used to selectively propagate L-type scrapie prions from a mixed prion population.

Here, we investigated chum salmon eggs (CSEs as a source of active ingredients, including vitamins, unsaturated fatty acids, and proteins. We incubated human dermal fibroblast cultures for 48 hours with high and low concentrations of CSE extracts and analyzed changes in gene expression. Cells treated with CSE extract showed concentration-dependent upregulation of collagen type I genes and of multiple antioxidative genes, including OXR1, TXNRD1, and PRDX family genes. We further conducted in silico phylogenetic footprinting analysis of promoter regions. These results suggested that transcription factors such as acute myeloid leukemia-1a and cyclic adenosine monophosphate response element-binding protein may be involved in the observed upregulation of antioxidative genes. Our results support the idea that CSEs are strong candidate sources of antioxidant materials and cosmeceutically effective ingredients.

    We aimed at assessing the effect of using a "Funada-kit II" device during laparoscopy-assisted percutaneous endoscopic gastrostomy (Lap-PEG), by reviewing 29 cases of Lap-PEG we performed from 2001 to 2011. We started using the "Funada-kit II" (CREATE MEDIC CO., Kanagawa, Japan) device with two parallel needles to puncture the stomach and assist suturing the anterior gastric wall to the anterior abdominal wall during Lap-PEG in 2011 (F-PEG). By introducing a loop through the lumen of one needle which allows placement of a suture introduced through the lumen of the other needle. Once repeated, the stomach can be pexied at two points, approximately 2 cm apart. We compared Lap-PEG (n = 23) with F-PEG (n = 6) where the mean ages and weights at surgery and sex ratios were similar. All cases were uneventful without intraoperative complications, although one postoperative wound infection occurred in a Lap-PEG case. There were no differences in the duration of analgesia, time taken to commence tube feeding, and return to full feeding. However, mean operating time was significantly shorter in F-PEG (28.1 min) versus Lap-PEG (46.1 min) p < 0.05. As per results F-PEG would appear to be as safe as Lap-PEG, but much quicker.

    Full Text Available Primary care is regarded as a setting that potentially mitigate patient health literacy (HL related inequalities. However, there is a lack of evidence about influence of patient HL on the patients' perception of quality of primary care. We aimed to examine the association between HL and patient experience of primary care attributes. We conducted a cross-sectional survey, and sent questionnaires to adult residents who were randomly selected from a basic resident register in Yugawara Town, Kanagawa, Japan. We assessed HL using a 14-item Health Literacy Scale (HLS-14 and patient experience of primary care attributes using a Japanese version of Primary Care Assessment Tool (JPCAT, which comprises six domains: first contact, longitudinality, coordination, comprehensiveness (services available, comprehensiveness (services provided, and community orientation. We used a multivariable linear regression analyses to adjust individual covariates. Data were analyzed for 381 residents who had a usual source of care. After adjustment for patients' sociodemographic and health characteristics, patient HL was positively associated with the JPCAT total score (B = 4.49, 95% confidence interval: 0.27 to 8.65 for HLS-14 total score highest quartile, compared with the lowest quartile. Among primary care attributes, HL had significant associations with longitudinality and comprehensiveness (service provided. We found that HL was positively associated with patient experience of primary care attributes in Japanese people. Our findings indicated that greater efforts might be needed to improve patient-centered and tailored primary care to those with low HL.

    To the compare the reading ability after bilateral cataract surgery in patients who had pseudophakic monovision achieved by monofocal intraocular lens (IOL) implantation and patients who had refractive multifocal IOL implantation. Department of Ophthalmology, Kitasato University Hospital, Kanagawa, Japan. This study evaluated patients who had bilateral cataract surgery using the monovision method with monofocal IOL implantation to correct presbyopia (monovision group) or who had bilateral cataract surgery with refractive multifocal IOL implantation (multifocal group). In the monovision group, the dominant eye was corrected for distance vision and the nondominant eye for near vision. The maximum reading speed, critical character size, and reading acuity were measured binocularly without refractive correction using MNREAD-J acuity charts. The monovision group comprised 38 patients and the multifocal group, 22 patients. The mean maximum reading speed was 350.5 characters per minute (cpm) +/- 62.3 (SD) in the monovision group and 355.0 +/- 53.3 cpm in the multifocal group; the difference was not statistically significant. The mean critical character size was 0.24 +/- 0.12 logMAR and 0.40 +/- 0.16 logMAR, respectively (P<.05). The mean reading acuity was 0.05 +/- 0.12 logMAR and 0.19 +/- 0.11 logMAR, respectively (P<.01). The monovision group had better critical character size and reading acuity results. The monovision method group had better reading ability; however, careful patient selection is essential.

    We investigated the effects of diabetes and the presence of lung cavities on treatment outcomes in patients with pulmonary tuberculosis. We conducted a retrospective review of the clinical records of all consecutive patients admitted to the Kanagawa Cardiovascular and Respiratory Centre with the diagnosis of pulmonary tuberculosis. The study outcomes examined were time to sputum culture conversion and percentage of patients with sputum culture conversion by the time 2 months of treatment, and these outcomes were compared between patients with and without diabetes. Of the 260 patients enrolled in the study, 69 were diagnosed as having diabetes mellitus, while the remaining 191 did not have diabetes. The percentage of patients with cavities was higher in the patients with diabetes (71.0%) than in those without (45.5%; P = 0.0003). The time to sputum culture conversion was significantly longer in the patients with diabetes than in those without (P = 0.0005), and the percentage of patients with a positive sputum culture at 2 months was higher in the patients with diabetes (43.5%) than in those without (18.8%; P = 0.0001). Multivariate analyses revealed that the presence/absence of lung cavities was a more important determinant of treatment outcomes than the presence/absence of diabetes. The presence of lung cavities was found to be a more important determinant of the treatment outcomes than that of diabetes per se in patients with pulmonary tuberculosis. © 2014 The Authors.

    A new national demonstration project of fuel cell vehicles, which is called Japan Hydrogen and Fuel Cell Demonstration Project (JHFC Project), has started in FY2002 on a four-year plan. In this new project, ten hydrogen fueling stations have been constructed in Tokyo and Kanagawa area in FY2002-2003. The ten stations adopt the following different types of fuel and fueling methods: LPG reforming, methanol reforming, naphtha reforming, desulfurized-gasoline reforming, kerosene reforming, natural gas reforming, water electrolysis, liquid hydrogen, by-product hydrogen, and commercially available cylinder hydrogen. Approximately fifty fuel cell passenger cars and a fuel cell bus are running on public roads using these stations. In addition, two hydrogen stations will be constructed in FY2004 in Aichi prefecture where The 2005 World Exposition (EXPO 2005) will be held. The stations will service eight fuel cell buses used as pick-up buses for visitors. We, Engineering Advancement Association of Japan (ENAA), are commissioned to construct and operate a total of twelve stations by Ministry of Economy Trade and Industry (METI). We are executing to demonstrate or identify the energy-saving effect, reduction of the environmental footprint, and issues for facilitating the acceptance of hydrogen stations on the basis of the data obtained from the operation of the stations.

    The antimicrobial substances in saliva contribute to the maintenance of both oral health and overall health of the body. Therefore, the associations among immunoglobulin A (IgA), lactoferrin and lysozyme flow rates in the saliva of children, and their relationships with the physical attributes and lifestyle factors of children, were examined. Saliva was collected from 90 children who visited the Kanagawa Dental University Hospital Pediatric Dentistry, and questionnaires were completed by guardians. IgA, lactoferrin and lysozyme concentrations were measured in the saliva samples using enzyme-linked immunosorbent assays (ELISAs). The IgA flow rate in saliva increased as age, height and weight increased. A correlation was found between lactoferrin and lysozyme flow rates. When the antimicrobial substance flow rates in the saliva were divided into two groups of 22 children each based on the highest and lowest quartiles, children with either a low or high IgA flow rate also had a high or low lactoferrin flow rate, respectively. The same pattern was observed for lactoferrin and lysozyme flow rates. There is a high probability that the IgA flow rate in the saliva of children reflects and corresponds to the developmental status of immune function as the child ages and increases in height and weight. The flow rates of lactoferrin and lysozyme were correlated in children. In addition, regarding lifestyle factors, the duration of sleep and lactoferrin flow rate were also related.

Time to discontinuation of treatment is also representative of effectiveness. We investigated differences in treatment discontinuation among newly started second-generation antipsychotics in the clinical setting.Methods: Using a retrospective cohort study design, we screened all outpatients (n = 7936 who visited the Shioiri Mental Clinic between July 1, 2008 and June 30, 2010. We identified a cohort of patients (n = 703 diagnosed with schizophrenia or schizoaffective disorder and calculated the time to discontinuation of each second-generation antipsychotic.Results: Of the 703 patients, 149 were newly treated with aripiprazole, 67 with blonanserin, 95 with olanzapine, 36 with quetiapine, 74 with perospirone, and 120 with risperidone. The time to discontinuation for all causes was significantly longer for aripiprazole than for blonanserin, olanzapine, and risperidone. In addition, aripiprazole tended to be continued for longer than quetiapine and perospirone, but these differences were not significant.Conclusion: Aripiprazole may be considered the best available option for long-term treatment of patients with schizophrenia or schizoaffective disorder.Keywords: retrospective study, second-generation antipsychotics, effectiveness, treatment continuation, schizophrenia, aripiprazole

  14. [Treatment approaches for synthetic drug addiction].

    In Japan, synthetic drugs have emerged since late 2000s, and cases of emergency visits and fatal traffic accidents due to acute intoxication have rapidly increased. The synthetic drugs gained popularity mainly because they were cheap and thought to be "legal". The Japanese government restricted not only production and distribution, but also its possession and use in April 2014. As the synthetic drug dependent patients have better social profiles compared to methamphetamine abusers, this legal sanction may have triggered the decrease in the number of synthetic drug dependent patient visits observed at Kanagawa Psychiatric Center since July 2014. Treatment of the synthetic drug dependent patients should begin with empathic inquiry into the motives and positive psychological effects of the drug use. In the maintenance phase, training patients to trust others and express their hidden negative emotions through verbal communications is essential. The recovery is a process of understanding the relationship between psychological isolation and drug abuse, and gaining trust in others to cope with negative emotions that the patients inevitably would face in their subsequent lives.

    Purpose: To define the influence of the tumor size measured by computed tomography (CT) and lymph node involvement detected by CT in patients treated with radiation therapy for Stage IIB-IVA carcinoma of intact uterine cervix. Methods and Materials: This was a retrospective analysis of 233 patients with uterine cervical cancer managed with both external irradiation and high-dose-rate intracavitary brachytherapy (HDR-ICR) at Kanagawa Cancer Center. The results were analyzed for the end points of absolute survival (AS), disease-free survival (DFS), pelvic control (PC), and central control (CC). The parameters of stage, CT-measured anterior-posterior (AP) cervix size, and CT-detected lymph node metastases were evaluated using univariate and multivariate analysis. Results: The stage, AP cervix size, and lymph node involvement were significant pretreatment factors in univariate analysis with respect to AS, DFS, PC, and CC. Multivariate analysis confirmed that significant risk was associated with certain prognostic parameters. Those in terms of AS, in order of decreasing significance, were lymph node involvement, AP cervix size, age, and total HDR-ICR dose. When DFS was studied, lymph node involvement and AP cervix size were demonstrated to have a significant effect. Stage and lymph node involvement significantly affected PC. Conclusion: Because the International Federation of Gynecological Obstetrics staging system fails to incorporate important prognostic information about tumor volume and lymph node involvement, CT-detected lymph node metastases as well as CT-measured cervix size should be determined as complementary additional prognostic measures

    Dementia care practitioner training is essential for professional caregivers to acquire medical knowledge and care skills for dementia patients. We investigated the significance of training in stress management by evaluating caregivers' job stress and coping style before and after they have completed training. The subjects included 134 professional caregivers (41 men, 93 women) recruited from participants in training programmes held in Kanagawa Prefecture from August 2008 to March 2010. A survey using a brief job stress questionnaire and a coping scale was carried out before and after they completed their training. A t-test and multiple regression analysis were performed to evaluate the effects of the training. After the training, the scores of modifiers on the job stress scale and of the coping scale increased, whereas the scores of stress reactions on the job stress scale decreased. However, there were no changes in participants' subjective cognition concerning their workplace environment. Furthermore, the change in stress reaction score tended to correlate with the change in consultation score in all participants and with the change in problem-solving and consultation in male participants. Among female participants, the change in stress reaction score tended to correlate with change in support from superiors and colleagues as modifiers. The factors that correlated to the change in stress reaction score differed between genders. The findings suggest that training caregivers improves their stress reaction and coping skills. © 2016 The Authors. Psychogeriatrics © 2016 Japanese Psychogeriatric Society.

    It is generally recognized that the earthquake response of a structure can be significantly affected by the dynamic interaction between the structure and the surrounding soil. Dynamic soil-structure interaction effects are usually analyzed by using a lumped mass model or a finite element model. In the lumped mass model, the soil is represented by springs and dashpots based on the half-space elastic theory. Each model has its advantages and limitations. The Three Dimensional Thin Layered Element Theory has been developed by Dr. Hiroshi Tajimi based on the combined results of the abovementioned lumped mass model and finite element model. The main characteristic of this theory is that, in consideration and can be applied in the analysis of many problems in soil-structure interaction, such as those involving radiation damping, embedded structures, and multi-layered soil deposits. This paper describes test results on a small scale model used to prove the validity of the computer program based on the Thin Layered Element Theory. As a numerical example, the response analysis of a PWR nuclear power plant is carried out using this program. The vibration test model is simplified and the scale is 1/750 for line. The soil layer of the model is made of congealed gelatine. The test soil layer is 80 cm long, 35 cm wide and 10 cm thick. The super structure is a one mass model made of metal sheet spring and solid mass metal. As fixed inputs, sinusoidal waves (10, 20 gal level) are used. The displacements of the top and base of the super structure, and the accelerations and the displacements of the shaking table are measured. The main parameter of the test is the shear wave velocity of the soil layer. (orig./RW)

When using the bottle models with inner aperture diameters of 0.4 mm or larger, the dispensing time became constant. The dispensing time using surfactant solution showed the same tendency as above. When pressure thrust load was large (0.07 MPa, the solution flew out continuously with inner aperture diameters of 0.4 mm or larger and the dispensing time could not be measured. The inner aperture diameter most strongly explained the variation of the dispensing time in both the content solutions in the multiple linear regression analysis (filtrate water: 46%, R2 = 0.462, surfactant solution: 56%, R2 = 0.563.Conclusions: Among content solutions and container structures, the dispensing time was mostly influenced by the diameter of the inner aperture of bottles.Keywords: dispensing time, model eye dropper bottle, model ophthalmic solution, nozzle internal space volume, nozzle inner aperture diameter

This study was designed to examine the effect of an ARB candesartan on subclinical atherosclerosis assessed by cardio-ankle vascular index (CAVI in comparison with calcium channel blockers (CCBs alone in hypertensive patients with metabolic syndrome (MetS. A total of 53 consecutive hypertensive patients with MetS were randomly assigned to the candesartan group, in which candesartan was added on, or the CCBs group, in which CCBs were added on. Clinical and biological parameters were obtained before and after the 12-month treatment period. The primary measure of efficacy was the %change in CAVI. When treated with candesartan, but not CCBs, CAVI significantly decreased from 8.7 to 7.7 by 11%. Blood pressure (BP significantly decreased with both treatments, but the differences between groups were not significant. The changes in other parameters remained unchanged in both the groups. Analysis of covariance found that both the BP reduction and the therapy difference contributed to the decrease in CAVI, but the BP reduction was not involved in the decrease in CAVI caused by the difference in the therapy. Candesartan may be a better antihypertensive drug than CCBs to that subclinical atherosclerosis of patients with MetS.Keywords: albuminuria, ambulatory blood pressure, calcium channel blockers, carotid ­intima-media thickness

Here, using a nanobeacon, the surface of which was fabricated with peanut agglutinin as TF-binding molecules, we demonstrate that the nanobeacon is able to detect TF antigen in frozen and freshly biopsied polyps using fluorescence microscopy. Our results provide important clues about how to detect aberrant colonic tissues in the most timely fashion. Given the versatile application method for this topical nanobeacon, the protocol used in this work is amenable to clinical colonoscopy. Moreover, the prospects of clinical translation of this technology are evident. Keywords: TF antigen

We report 13 Japanese adolescents or young adults with Down syndrome who developed acute neuropsychiatric disorders including withdrawal, depression, obsessive-compulsive behaviors, and occasional delusions or hallucinations.Methods: The following information was collected from each patient: age at onset of acute neuropsychiatric disorder, complications, signs and symptoms, personality traits before the onset of the acute neuropsychiatric disorder, prescribed medications with their respective doses and the response to treatment, and senile changes observed on magnetic resonance imaging or computed tomography.Results: The mean age at onset of these disorders was 21.2 years. Brain imaging showed almost senile changes; patients responded well to low-dose psychotropic therapy. Patients had an onset at a young age and presented with treatable conditions, although the average age of the onset of Alzheimer’s disease is generally over 40 years of age in patients with Down syndrome.Conclusion: These findings suggest that the pathology of acute neuropsychiatric disorder in patients with Down syndrome may be related to presenile changes; however, these disorders present features and a clinical course that is different from those presented in typical Alzheimer’s disease with Down syndrome.Keywords: Down syndrome, acute neuropsychiatric disorders, Alzheimer’s disease

Purpose: The objective of this study was to characterize the population pharmacokinetics of olprinone after a single continuous infusion in healthy male volunteers. Methods: We used 500 plasma concentration data points collected from nine healthy male volunteers for the study. The population pharmacokinetic analysis was performed using the nonlinear mixed effect model (NONMEM® software. Results: The time course of plasma concentration of olprinone was best described using a two-compartment model. The final pharmacokinetic parameters were total clearance (7.37 mL/minute/kg, distribution volume of the central compartment (134 mL/kg, intercompartmental clearance (7.75 mL/minute/kg, and distribution volume of the peripheral compartment (275 mL/kg. The interindividual variability in the total clearance was 12.4%, and the residual error variability (exponential and additive were 22.2% and 0.129 (standard deviation. The final pharmacokinetic model was assessed using a bootstrap method and visual predictive check. Conclusion: We developed a population pharmacokinetic model of olprinone in healthy male adults. The bootstrap method and visual predictive check showed that this model was appropriate. Our results might be used to develop the population pharmacokinetic model in patients.

    Full Text Available Akira Watanabe, Tamaki Gekka, Hiroshi Tsuneoka Department of Ophthalmology, The Jikei University School of Medicine, Tokyo, Japan Background: As a method of treatment for a dropped lens nucleus, which occurred during cataract surgery, the dropped lens nucleus was removed through the corneal wound without using pars plana vitrectomy (PPV. After vitrectomy, the dropped lens nucleus was floated on the perfluorocarbon liquid (PFCL. The floating lens nucleus was then phacoemulsified and aspirated. During surgery, irrigation from the anterior chamber was performed. This method was very effective for treatment of a dropped hard nucleus.Case report: During cataract surgery on the left eye of an 80-year-old woman, a posterior capsule rupture occurred. As a result, the lens nucleus dropped into the vitreous cavity. Irrigation to the anterior chamber was performed, with an anterior chamber maintainer inserted through a newly created side port at the corneal limbus. A vitreous cutter and a light guide were inserted in order to perform vitrectomy through the corneal incisions that were created for the cataract surgery. After vitrectomy, the dropped lens nucleus was floated using PFCL. The floating lens nucleus was removed by a bimanual phacoemulsification technique, with the anterior chamber irrigation continuing. The separation of the irrigation port and the aspiration port allowed for effective treatment of the dropped nucleus that was floating on the PFCL, even using a ­phacoemulsification machine with a peristaltic pump system. Safe and effective vitrectomy, similar to a PPV, could be performed with this method using three corneal ports.Conclusion: This technique may allow safer and more effective treatment for a dropped lens nucleus compared with conventional PPV. With this technique, corneal distortion due to surgical manipulation can lead to reduced visibility of the posterior eye. Keywords: dislocated lens, transcorneal vitrectomy, bimanual

Although the origin of the IS/OS in optical coherence tomography (OCT images is unclear, it may be related to either the cellular activity of the photoreceptors or the structure of the OS disks. To address this question, we compared the IS/OS status in OCT images of rat retinas before and after euthanasia.Methods: OCT images were taken before and after euthanasia in four eyes of two Brown Norway rats. After the OCT images were taken, the rats were used for histopathological studies to confirm that retinal structures were intact.Results: Before euthanasia, the IS/OS and external limiting membrane (ELM line were clearly identifiable on the OCT images. However, after euthanasia, neither the IS/OS nor the ELM line was evident in three out of four eyes, and a faint IS/OS and an ELM line were identified in one eye. Histopathological analysis did not show any abnormalities in the retina in any of the four eyes.Conclusion: The origin of the IS/OS identified in OCT images is likely related to the biological activities of the photoreceptor cells.Keywords: IS/OS, OCT, histopathology, biological activity

Our inherent understanding indicates that stem cells have been in existence since the birth of multicellular organisms. However, the formal discovery of stem cells in the last century, followed by their intricate and extensive analysis, has led to clinical and translational efforts with the aim of using them in the treatment of conditions which don't have a definitive therapeutic strategy, has fueled our interest and expectations. Technological advances in our ability to study their cellular components in depth, along with surface markers and other finer constituents, that were unknown until last century, have improved our understanding, leading to several novel applications. This has created a need to establish guidelines, and in that process, there are expressed understandings and views which describe cell therapy along lines similar to that of biologic products, drugs, and devices. However, the age-old wisdom of using cells as tools for curing illness should not be misled by recent knowledge, to make cell therapy using highly complex stem cells equal to factory-synthesized and reproducible chemical compounds, drugs, or devices. This article analyses the differences between these two entities from various perspectives. Keywords: cell transplantation, drugs, regenerative medicine, stem cells

Recently, fondaparinux and edoxaban are being used as beneficial alternatives to UFH and VKA.Methods: We evaluated the clinical course of symptomatic deep vein thrombosis (DVT in patients who received the 3-month anticoagulation therapy with fondaparinux/edoxaban (Group A; n=40 in comparison with the findings from our previous experience of patients who received the fondaparinux/VKA combination (Group B; n=33.Results: In both Groups A and B, serum D-dimer was significantly improved after treatment (p<0.001. The thrombus volume assessed by quantitative ultrasound thrombosis (QUT score was significantly reduced in both groups (p<0.001. There was no difference in the proportion of patients who were normalized (ie, disappearance of DVT between the groups, although Group A had significantly more patients who were normalized or improved (ie, disappearance and reduction of DVT (p<0.001. No bleeding event was observed in either group. However, in one patient in Group B, worsening of DVT and development of symptomatic PE were observed.Conclusion: Fondaparinux/edoxaban therapy is as effective as fondaparinux/VKA. This treatment has the possible advantage in thrombus regression. This would be a beneficial therapeutic option for both patients and physicians.

We investigated the hypothesis that meal consumption may reduce tongue strength and endurance in older adults (OAs.Methods: Tongue–palate pressure, oral diadochokinesis, repetitive saliva swallowing, and surface electromyography activity before and after a meal were measured in 23 young adults (YAs and 23 OA volunteers.Results: There was a statistically significant difference in both tongue pressure and the number of voluntary swallows between YAs and OAs. Peak tongue pressure was significantly lower in OAs than YAs both before and after meal consumption. The most notable finding was that the first time interval (the time from test initiation to the beginning of the first swallow was prolonged after meal consumption only in OAs, whereas the first time interval showed no difference between YAs and OAs before meal consumption with reference to the repetitive saliva swallowing test. The initiation of swallowing was prolonged by both meal consumption and aging; there was a significant interaction between these two factors. The number of repetitions of the monosyllable/pa/was statistically similar between YAs and OAs before meal consumption, but it was significantly lower in OAs after meal consumption.Conclusion: Aging leads to declining tongue pressure and motor function of the lips. It is possible that swallowing function declines in older individuals when meal consumption is prolonged, especially at the end of mealtime, as a result of their

The larvae was removed to the labeled diet with increasing level of the elements Mn, Sr and Cu. The levels tested for all element were: 0 (control); 0,25; 0,50; 1,00; 2,00; 4,00; 8,00; 16,00; 32,00 and 64,00 mg/gr of diet. Labeled pupae with 1,00 to 4,00 (Mn) and 1,00 (Sr and Cu) mg/gr of diet were tested for the pupal parasitoid M. uniraptor. The concentration quantity of the chemical elements was realized by the Analytical Technique denominated (EDXRF) energy dispersive X-ray fluorescence. Concentrations of 2,00 (Mn) and 1,00 (Sr) supplemented to the diet of M. domestica were sufficient for the adult insect labeled, however, not affecting its life expectancy. Pupae originated from the larvae of M. domestica treated with dose of 2,00 (Mn) and 1,00 (Sr and Cu) mg supplemented to the diet, and used as hosts of the parasitoid M. uniraptor, affected the viability of the immature phase and did not label the adults.

    Photoinitiated free radical polymerization of donor (D)/acceptor (A) type monomers has gained considerable interest due to the possibility to efficiently photopolymerize non-acrylate based systems. Furthermore, this photoinduced alternating copolymerization can be accomplished without the presence of a conventional free radical generating photoinitiator. In the past, we have shown that the structural influences in the direct photolysis of N-Alkyl and N-Arylmaleimides as well as their corresponding ground state charge transfer complexes (CTC) with suitable donors have carefully been investigated. For certain combinations of A and D type monomers, a direct photolysis of the ground state complex or the excitation of the acceptor, followed by the formation of an exciplex, has been shown to initiate the copolymerization. Herein, we show that the main route of initiation is based on inter or intra molecular H-abstraction from an excited state maleimide, whereby no exciplex formation takes place. H-abstraction will predominantly take place in systems where easily abstractable hydrogens are present. Our laser flash photolysis investigation, ESR (A. Hiroshi, I. Takasi, T. Nosi, Macromol. Chem. 190 (1989) 2821) and phosphorescence emissions (K.S. Chen, T. Foster, J.K.S. Wan, J. Phys. Chem. 84 (1980) 2473; C.J. Seliskar, S.P. McGlynn, J. Chem. Phys. 55 (1971) 4337) studies show that triplet excited states of N-alkyl substituted maleimides (RMI), which are well known strong precursors for direct H-abstractions from aliphatic ethers and secondary alcohols, are formed upon excitation. Rates of copolymerization and degrees of conversion for copolymerization of maleimide/vinyl ether pairs in air and nitrogen have been measured as a function of hydrogen abstractability of the excited triplet state MI as well as the influence of concentration and hydrogen donating effect of the hydrogen donor

We defined an “early improvement group” in which delirium resolved in ≤3 days after starting psychiatric medication, and a “prolonged group” with delirium lasting for >3 days. Among the 83 inpatients with renal dysfunction (estimated glomerular filtration rate <60 mL/min/1.73 m2, we defined an “early improvement group with renal dysfunction” in which delirium resolved in ≤3 days after starting psychiatric medication and a “prolonged group with renal dysfunction” with delirium lasting for >3 days. We then examined differences between groups for different categorical variables.Results: Dose of antipsychotic medication at end point was significantly lower in the prolonged group with renal dysfunction than in the early improvement group with renal dysfunction.Conclusion: The results suggest that maintaining a sufficient dose of antipsychotics from an early stage may prevent prolongation of delirium even in inpatients with renal dysfunction.

In this prefecture, a new medical system called the remote online hemodynamic monitoring system (ROHMs was started in 2001. Eight private dental offices participated in this trial. When dental practitioners feel the risk of a dental procedure, they can contact via ROHMs to this hospital. Then, the hemodynamic data (blood pressure, heart rate, ECG, SpO2, and RPP of the patient in the clinic can be transmitted here via the internet, and the images and the voice can be transmitted as well. The availability of this system was assessed in 66 patients (98 cases. The most frequent complications were hypertension, heart disease, and diabetes mellitus. Systemic management included monitoring during the dental procedure (71.4%, checking vital signs after an interview (15.3%, and monitoring under sedation (13.3%. There were 35.7% of all cases where an unscheduled procedure was necessary for the systemic management. Based on a questionnaire, the majority of the patients felt relieved and safe. This system creates a situation where a specialist is almost present during the procedure. This system will provide significant assistance for future medical cooperation for risk management.Keywords: online, high-risk patient, dental treatment, medical cooperation, medical accident, risk management

However, little is known about the nutritional status in non-COPD aging men with smoking history. We therefore investigated whether reduced lung function is associated with lower blood markers of nutritional status in those men.Subjects and methods: This association was examined in a cross-sectional study of 65 Japanese male current or former smokers aged 50 to 80 years: 48 without COPD (non-COPD group, divided into tertiles according to forced expiratory volume in one second as percent of forced vital capacity (FEV1/FVC, and 17 with COPD (COPD group.Results: After adjustment for potential confounders, lower FEV1/FVC was significantly associated with lower red blood cell count (RBCc, hemoglobin, and total protein (TP; not with total energy intake. The difference in adjusted RBCc and TP among the non-COPD group tertiles was greater than that between the bottom tertile in the non-COPD group and the COPD group.Conclusion: In non-COPD aging men with smoking history, trends toward reduced nutritional status and anemia may independently emerge in blood components along with decreased lung function

    Burnout is a common feature among healthcare professionals; however, little systematic research exists on burnout among nurses who are raising children. The burnout-related factors among female nurses with children under the age of 3 years were identified in order to ascertain potential burnout prevention methods. In total, 1681 nurses with children who worked at nine city hospitals in Kanagawa Prefecture, Japan, were sent the Maslach Burnout Inventory-Human Services Survey; 1173 nurses responded in June 2014. They were divided according to their sex and children's ages. A data analysis was undertaken for those female nurses with children who were aged under 3 years who provided valid responses (n = 158). A number of factors related to burnout in female nurses with children aged under 3 years was found via a multiple regression analysis: irritation at being unable to attend to their own affairs, over 4-6 h of overtime work per week, having a child aged under 3 years as the first or second child, little sense of work fulfillment, using a childcare facility outside the workplace, dissatisfaction with their salary, feeling ill-qualified as a parent, and a sense of inadequate support. Child care occurs during a limited period and appropriate support is needed. A workplace environment with no overtime work, a childcare facility in the workplace, and mental health support to reduce "feelings of irritation" and "feeling ill-qualified as a parent" could help to prevent burnout in female nurses with toddlers and infants. © 2016 Japan Academy of Nursing Science.

To study episodic memory in OCD patients, we examined the directed forgetting effect. Patients with OCD and healthy control participants were given a list of 24 emotionally neutral everyday words (12 remember [R]-cued words and 12 forget [F]-cued words under two conditions: List and Item. The results of our study showed that OCD patients recalled a number of F-cued words similar to that for controls and relatively fewer R-cued words than controls under both List and Item conditions. Consequently, the directed forgetting effect was smaller in OCD patients than controls. Our results demonstrated that both selective encoding and retrieval inhibition processes are impaired in OCD, and we suggest that recall of unfavorable items to be forgotten intruded into necessary items to be remembered. This impairment in episodic memory may partially account for some of the unique clinical symptoms of OCD.Keywords: episodic memory, retrieval inhibition, selective encoding

In general, risk preference is closely related to socioeconomic status (SES, which includes factors such as age, sex, income, and educational attainment.Objective: We aimed to determine the effect of SES and behavioral propensity on the progress of diabetic complications in patients with type 2 diabetes mellitus (T2DM.Methods: We conducted a survey of 238 patients with difficult-to-control T2DM treated at a hospital in Japan using a modified behavioral economics questionnaire that included questions related to SES. The patients had been referred by general practitioners or other departments in the hospital because of poor metabolic control or unstable complications.Results: Educational attainment was significantly associated with progression of retinopathy in patients <65 years of age. Educational attainment of a high school diploma (12 years of education or lower was a significant risk factor, but there were no differences among levels of attainment beyond high school (13–16 years or more of education. Behavioral propensities were also weakly associated with complications, but not as much as educational attainment. Personal income level and economic status did not show an association with the retinopathy levels.Conclusion: Lower educational attainment is a strong risk factor for diabetic retinopathy, and it is independent of the economic status. The result suggests that cognitive function may play an important role in the progression of diabetic retinopathy in

These factors do not fully reflect the costs of care for each patient. The objective of this study was to clarify the relationship between patient characteristics and their care costs as measured by “care time” for patients with schizophrenia.Methods: Patient characteristics and care time were investigated in 14,557 inpatients in 102 psychiatric hospitals in Japan. Of these 14,557 inpatients, data for 8,379 with schizophrenia were analyzed using a tree-based model.Results: The factor exerting the greatest influence on care time was ”length of stay”, so subjects were divided into 2 groups, a “short stay group” with length of stay ≦104 days, and “long stay group” ≧105 days. Each group was further subdivided according to dependence with regard to “activities of daily living”, “psychomotor agitation”, “verbal abuse”, and “frequent demands/repetitive complaints”, which were critical variables affecting care time. The mean care time was shorter in the long-stay group; however, in some long-stay patients, the mean care time was considerably longer than that in patients in the short-stay group.Conclusion: The results of this study suggest that it is necessary to construct a new payment system reflecting not only length of stay and nurse staffing levels, but also individual patient characteristics.

    Full Text Available Chieko FujiiFaculty of Nursing and Medical Care, Keio University, Kanagawa, JapanBackground: Complications resulting from venipuncture include vein and nerve damage, hematoma, and neuropathic pain. Although the basic procedures are understood, few analyses of actual data exist. It is important to improve the safety standards of this technique during venipuncture. This study aimed to obtain data on actual needle movement during vacuum venipuncture in order to develop appropriate educational procedures.Methods: Six experienced nurses were recruited to collect blood samples from 64 subjects. These procedures were recorded using a digital camera. Software was then used to track and analyze motion without the use of a marker in order to maintain the sterility of the needle. Movement along the X- and Y-axes during blood sampling was examined.Results: Approximately 2.5 cm of the needle was inserted into the body, of which 6 mm resulted from advancing or moving the needle following puncture. The mean calculated puncture angle was 15.2°. Given the hazards posed by attaching and removing the blood collection tube, as well as by manipulating the needle to fix its position, the needle became unstable whether it was fixed or not fixed.Conclusion: This study examined venipuncture procedures and showed that the method was influenced by increased needle movement. Focusing on skills for puncturing the skin, inserting the needle into the vein, and changing hands while being conscious of needle-tip stability may be essential for improving the safety of venipuncture.Keywords: blood collection, nerve damage, motion analysis, patient safety, puncture angle, clinical education

We proposed a new combination skin care for infants which consisted of a foaming cleanser with lower surfactant activity and moisturizers that contained pseudo-ceramide. Subjects and methods: A total of 50 infants (age: 3–24 months with insignificant levels of dry skin were enrolled in this usage trial. The parents washed the infants with the test cleanser while bathing and then applied the moisturizer (lotion or cream containing pseudo-ceramide. Prior to and following the 4-week usage period, visual evaluation of the skin condition was conducted by a dermatologist, in addition to instrumental analysis. Results: Erythema and papule, accompanied by dryness, were commonly observed at week 0. However, by week 4, these symptoms significantly improved; the condition of none of the subjects deteriorated. The number of infants with lower cutaneous barrier function and higher skin pH decreased. The parents of the infants recognized improvements in the skin symptoms and were appreciative of the test materials. Conclusion: The combined usage of the foaming cleanser with lower surfactant activity and a moisturizer containing pseudo-ceramide may be effective in maintaining healthy infant skin and ameliorating the skin symptoms.

Daily cocoa intake has been shown to reduce central arterial stiffness in health adults, regardless of age; however, the effect of cocoa-intake frequency on arterial stiffness in postmenopausal women remains unclear. Therefore, the purpose of this study was to investigate the effects of cocoa-intake frequency on arterial stiffness in postmenopausal women. A total of 26 postmenopausal women (mean age ± standard deviation 64±12 years were randomly assigned to two groups with different cocoa-intake frequencies: one group ingested 17 g of cocoa once daily except on Sundays (every-day group, n=13, and the other ingested 17 g of cocoa twice daily every other day (every-other-day group, n=13. These intake regimens were maintained in both groups for 12 weeks. Carotid–femoral pulse-wave velocity and femoral–ankle pulse-wave velocity were measured in both groups at baseline and again at the end of the 12-week study period. Compared to baseline, both pulse-wave velocities had significantly decreased after the 12-week study period in both groups (P<0.05. However, no significant difference in degree of change was observed between the two groups. Although this study did not include a sedentary control group, these results suggest that regardless of frequency, habitual cocoa intake reduces central and peripheral arterial stiffness in postmenopausal women.

    The association between oxidative stress and exposure to environmental chemicals was assessed in a group of Japanese preschool children. The concentrations of 8-hydroxy-2'-deoxyguanosine (8-OHdG), 1-hydroxypyrene (1-OHP), inorganic arsenic (iAs) and monomethylarsonic acid (MMA), and cotinine in spot urine samples, collected from 134 children (3-6 yrs) from a kindergarten in Kanagawa, Japan, were measured as biomarkers of oxidative stress or exposure to environmental chemicals. For 76 subjects of the 134, intakes of anti-oxidant nutrients (vitamins A, C, and E, manganese, copper, zinc and selenium (Se)) were estimated from a food consumption survey carried out 2-4 weeks after urine sampling and by urine analysis (Se). The median (min-max) creatinine-corrected concentrations of urinary biomarkers were 4.45 (1.98-12.3), 0.127 (0.04-2.41), 4.78 (1.18-12.7), and 0.62 (iAs+MMA, and cotinine, respectively. Multiple regression analysis was carried out using 8-OHdG concentration as a dependent variable and urinary biomarkers of exposure and Se intake, intakes of vitamins and biological attributes of the subjects as independent variables. To explain 8-OHdG concentrations, intake of vitamin A and age were significant variables with negative coefficients, while 1-OHP concentration had a positive coefficient. These results indicated that oxidative stress of children is affected by chemical exposure at environmental levels, by nutrient intake and by physiological factors in a complex manner. On the other hand, unstable statistical results due to sub-grouping of subject, based on the availability of food consumption data, were found: the present results should further be validated by future studies with suitable research design.

    Although Japan has been considered to have little lead (Pb) pollution in modern times, the actual pollution situation is unclear. The present study aims to investigate the extent of Pb pollution and to identify the pollution sources in Japan using stable Pb isotope analysis with kidneys of wild rats. Wild brown ( Rattus norvegicus , n = 43) and black ( R. rattus , n = 98) rats were trapped from various sites in Japan. Mean Pb concentrations in the kidneys of rats from Okinawa (15.58 mg/kg, dry weight), Aichi (10.83), Niigata (10.62), Fukuoka (8.09), Ibaraki (5.06), Kyoto (4.58), Osaka (4.57), Kanagawa (3.42), and Tokyo (3.40) were above the threshold (2.50) for histological kidney changes. Similarly, compared with the previous report, it was regarded that even structural and functional kidney damage as well as neurotoxicity have spread among rats in Japan. Additionally, the possibility of human exposure to a high level of Pb was assumed. In regard to stable Pb isotope analysis, distinctive values of stable Pb isotope ratios (Pb-IRs) were detected in some kidney samples with Pb levels above 5.0 mg/kg. This result indicated that composite factors are involved in Pb pollution. However, the identification of a concrete pollution source has not been accomplished due to limited differences among previously reported values of Pb isotope composition in circulating Pb products. Namely, the current study established the limit of Pb isotope analysis for source identification. Further detailed research about monitoring Pb pollution in Japan and the demonstration of a novel method to identify Pb sources are needed.

    In 2001, we summarized the circumstances surrounding termination of the JCO criticality accident based on testimony in the Mito District Court on December 17, 2001. JCO was the company for uranium fuels production in Japan. That document was assembled based on actual testimony in the belief that a description of the work involved in termination of the accident would be useful in some way for preventing nuclear disasters in the future. The description focuses on the witness' own behavior, and what he saw and heard, and thus is written from the perspective of action by one individual. This was done simply because it was easier for the witness to write down his memories as he remembers them. Description of the activities of other organizations and people is provided only as necessary, to ensure that consistency in the descriptive approach is not lost. The essentials of this report were rewritten as a third-person objective description in the summary of the report by the Atomic Energy Society of Japan (AESJ). Since then, comments have been received from sources such as former members of the Nuclear Safety Commission (Dr. Kenji Sumita and Dr. Akira Kanagawa), concerned parties from the former Science and Technology Agency, and reports from the JCO Criticality Accident Investigation Committee of the AESJ, and thus this report was rewritten to correct incorrect information, and add material where that was felt to be necessary. This year is the tenth year of the JCO criticality accident. To mark this occasion we have decided to translate the record of what occurred at the accident site into English so that more people can draw lessons from this accident.

    The present study examines job-related factors leading to low self-esteem in nurses. The lowering of self-esteem suggests that such nurses had difficulty in fully accepting themselves and their circumstances. Subjects were registered nurses (RN) and licensed practical nurses (LPN) at hospitals, and unemployed registered nurses (UEN) seeking employment. Questionnaires were provided at 53 hospitals and a Nurse Bank in Kanagawa Prefecture. The responses of 552 RN, 146 LPN and 433 UEN were analyzed. Questions were asked about personal life, past or present nursing experience, working conditions, nursing skills, satisfaction with work performance and self-esteem. Factors giving rise to low self-esteem were determined using logistic regression analysis and logistic discriminant analysis. Employment status and qualifications were determined to be the most important factors determining the self-esteem of nurses. The next most important factors were 'a limited number of years of experience (less than five years)' and 'dissatisfaction with discretion and responsibility as a nurse' (P self-esteem for LPN was 4.07 times higher than for UEN, and 2.2 times higher than for RN by logistic regression analysis. LPN are treated as unskilled workers, and thus significant differences were apparent in their performance of certain job tasks. These differences were analyzed using discriminant analysis, and were referred to as follows, 1: Advanced assessment skills, 2: Advanced technical skills, 3: Advanced communication skills, and 4: Nursing plan and documentation (positive discrimination rate was 70.8%). Job dissatisfaction is closely associated with the level of professional training. Continuous education and a feedback system for various levels of nurses are needed.

The authors examined social and geographical inequalities in suicide in Japan from 1975 through 2005.Based on quinquennial vital statistics and census data, the authors analyzed the entire population aged 25-64 years. The total number of suicides was 75,840 men and 30,487 women. For each sex, the authors estimated odds ratios (ORs and 95% credible intervals (CIs for suicide using multilevel logistic regression models with "cells" (cross-tabulated by age and occupation at level 1, seven different years at level 2, and 47 prefectures at level 3. Prefecture-level variance was used as an estimate of geographical inequalities in suicide.Adjusting for age and time-trends, the lowest odds for suicide was observed among production process and related workers (the reference group in both sexes. The highest OR for men was 2.52 (95% CI: 2.43, 2.61 among service workers, whereas the highest OR for women was 9.24 (95% CI: 7.03, 12.13 among security workers. The degree of occupational inequalities increased among men with a striking change in the pattern. Among women, we observed a steady decline in suicide risk across all occupations, except for administrative and managerial workers and transport and communication workers. After adjusting for individual age, occupation, and time-trends, prefecture-specific ORs ranged from 0.76 (Nara Prefecture to 1.36 (Akita Prefecture for men and from 0.79 (Kanagawa Prefecture to 1.22 (Akita Prefecture for women. Geographical inequalities have increased primarily among men since 1995.The present findings demonstrate a striking temporal change in the pattern of social inequalities in suicide among men. Further, geographical inequalities in suicide have considerably increased across 47 prefectures, primarily among men, since 1995.

    We developed the palm size (optical unit: 73[mm]×102[mm]×66[mm]) and light weight (total weight with electrical controller: 1.7[kg]) middle infrared (wavelength range: 8[μm]-14[μm]) 2-dimensional spectroscopy for UAV (Unmanned Air Vehicle) like drone. And we successfully demonstrated the flights with the developed hyperspectral camera mounted on the multi-copter so-called drone in 15/Sep./2015 at Kagawa prefecture in Japan. We had proposed 2 dimensional imaging type Fourier spectroscopy that was the near-common path temporal phase-shift interferometer. We install the variable phase shifter onto optical Fourier transform plane of infinity corrected imaging optical systems. The variable phase shifter was configured with a movable mirror and a fixed mirror. The movable mirror was actuated by the impact drive piezo-electric device (stroke: 4.5[mm], resolution: 0.01[μm], maker: Technohands Co.,Ltd., type:XDT50-45, price: around 1,000USD). We realized the wavefront division type and near common path interferometry that has strong robustness against mechanical vibrations. Without anti-mechanical vibration systems, the palm-size Fourier spectroscopy was realized. And we were able to utilize the small and low-cost middle infrared camera that was the micro borometer array (un-cooled VOxMicroborometer, pixel array: 336×256, pixel pitch: 17[μm], frame rate 60[Hz], maker: FLIR, type: Quark 336, price: around 5,000USD). And this apparatus was able to be operated by single board computer (Raspberry Pi.). Thus, total cost was less than 10,000 USD. We joined with KAMOME-PJ (Kanagawa Advanced MOdule for Material Evaluation Project) with DRONE FACTORY Corp., KUUSATSU Corp., Fuji Imvac Inc. And we successfully obtained the middle infrared spectroscopic imaging with multi-copter drone.

    Total mercury in the muscles of three fish species was analyzed in fish caught in Tokyo Bay and the surrounding sea areas, Sagami Bay and Choshi. Tokyo Bay is a semi-closed sea area surrounded by Tokyo, Kanagawa and Chiba prefectures. Sagami Bay and Choshi are open to the Pacific Ocean. A total of 412 fish consisting of northern whiting (Sillago japonica), flatfish (Limanda yokohamae) and sardine (Sardinops melanosticta) were caught in these areas over a 6 months period from November 1998 to April 1999. Total mercury concentration ranged from 0.008-0.092 microgram/g (wet wt.) in northern whiting, 0.006-0.065 microgram/g in flatfish and 0.001-0.045 microgram/g in sardine. All concentrations were below the restriction limit of fish mercury in Japan, 0.4 microgram/g of total mercury concentration. A significant correlation was found between mercury concentrations and body length or body weight in northern whiting and flatfish, irrespective of the sea area. A correlation was also found between mercury concentration in fish and their feeding habits: among the 3 species caught in the same area, crustacean feeding northern whiting had the highest, polychaete feeding flatfish moderate, and plankton feeding sardine had the lowest mercury concentration. In a comparison of mercury concentration in the same species caught in different sea areas, a higher concentration was noted in fish caught in the semi-closed sea area of Tokyo Bay, than in fish caught in the open sea areas of Sagami Bay and Choshi. This difference was most marked in fish caught at the bottom of Tokyo Bay and we considered that the mercury concentration of seawater and sediment in these areas was the cause of mercury accumulation in fish. These findings suggest that improved water quality control and environmental monitoring is necessary in semi-closed sea areas such as Tokyo Bay.

    Wind characteristics are observed in the period November 1997 through October 1998 at Yugawara Town, Kanagawa Prefecture. The average wind speed is 5.1m/s and 5.0m/s at 20m and 10m above ground, respectively, suggesting that the difference in altitude causes but a very small difference in wind speed and that a large wind speed component exists in the vertical direction. Under the 16 compass point system, the wind direction occurrence rate is the highest in the NE direction and the second highest in the W direction. The two directions are prevalent, and their occurrence rates on the wind axes total 62.6%. The occurrence rate of wind speeds of not less than 5m/s is 40%. Turbulence intensity is 0.23 and 0.17 for the average wind speed of not less than 2m/s and for the average wind speed of not less than 4m/s, respectively, suggesting but a little impact of air current turbulence. The amounts of energy to be acquired by wind turbine systems of 150kW, 300kW, and 750kW are estimated at 301,363kWh, 651,593kWh, and 1,668,825kWh, respectively. Their annual capacity ratios are 22.9%, 24.8%, and 25.4%, respectively. Since difference in wind speed due to difference in altitude is small, it is supposed that the wind speed at the hub altitude is not so high. It is inferred consequently that service operation will be quite difficult to realize. Difficulties will be also encountered in relation to the route of turbine system transportation, power distribution line, and the distance to a transformation station. (NEDO)

    A nationwide survey of ixodid ticks was performed in 2011, during which a total of 4237 and 298 ticks were recovered from 1162 dogs and 136 cats, respectively. Haemaphysalis longicornis was the most frequently found tick species on canine hosts (739 dogs), followed by H. flava (166), Ixodes ovatus (139), and Rhipicephalus sanguineus sensu lato (70). H. hystricis, H. japonica, H. megaspinosa, H. formosensis, H. campanulata, H. ias, I. nipponensis, I. persulcatus, and Amblyomma testudinarium were also recovered. H. longicornis was also the most frequently found species on feline hosts (52 cats), followed by I. ovatus (34), A. testudinarium (19), and H. flava (12). H. hystricis, H. japonica, H. megaspinosa, I. nipponensis, I. persulcatus, I. granulatus and R. sanguineus sensu lato were also recovered from cats. The three major species of ticks found on dogs and cats, H. longicornis, H. flava, and I. ovatus, displayed a wide geographical distribution, with specimens found throughout northern and southern Japan. R. sanguineus sensu lato was primarily recovered in Okinawa, but was also found in Kanagawa, Wakayama, Hiroshima, and Yamaguchi Prefectures. A. testudinarium was mainly distributed throughout western Japan, but small numbers were also recovered from Gumma and Shizuoka Prefectures. H. longicornis was more frequently found on dogs in rural areas than those in urban or suburban areas. Exposure to woodland environments was significantly associated with H. flava and I. ovatus in dogs. Dogs in urban or suburban areas encountered R. sanguineus sensu lato more often than other tick species. Most of the cats surveyed in the present study were from rural areas. In the present study, H. hystricis and R. sanguineus sensu lato were found on cats for the first time in Japan. Copyright © 2014 Elsevier GmbH. All rights reserved.

    Buckwheat (BW) is the source of a life-threatening allergen. Fag e 3-specific serum IgE (sIgE) is more useful than BW-sIgE for diagnosis; however, it is unknown whether Fag e 3-sIgE can predict oral food challenge (OFC) results and anaphylaxis. This study aimed to clarify the efficacy of Fag e 3-sIgE in predicting OFC results and anaphylaxis. We conducted a retrospective review of BW- and Fag e 3-sIgE data obtained using the ImmunoCAP® assay system and fluorescent enzyme-linked immunosorbent assay from children who underwent OFC using 3,072 mg of BW protein between July 2006 and March 2014 at Sagamihara National Hospital, Kanagawa, Japan. We analyzed 60 patients aged 1.9-13.4 years (median 6.0 years); 20 (33%) showed objective symptoms upon BW OFC. The patients without symptoms had significantly lower Fag e 3-sIgE than those with non-anaphylactic (p tested factor that significantly predicted positive OFC results (odds ratio 8.93, 95% confidence interval 3.10-25.73, p < 0.001) and OFC-induced anaphylaxis (2.67, 1.12-6.35, p = 0.027). We suggest that a threshold Fag e 3-sIgE level of 18.0 kUE/L has 95% probability of provoking a positive reaction to BW. Fag e 3-sIgE predicted OFC results and OFC-induced anaphylaxis. We further emphasize paying careful attention to the risk of BW OFC-induced anaphylaxis. © 2018 The Author(s) Published by S. Karger AG, Basel.

    Existing literature suggests that influenza C typically causes mild respiratory tract disease. However, clinical and epidemiological data are limited. Four outpatient clinics and 3 hospitals submitted clinical data and respiratory specimens through a surveillance network for acute respiratory infection (ARI) from May 2013 through December 2016. Specimens were tested using multitarget nucleic acid amplification for 19-22 respiratory pathogens, including influenza C. Influenza C virus was detected among 59 of 10 202 (0.58%) hospitalized severe ARI cases and 11 of 2282 (0.48%) outpatients. Most detections occurred from December to March, 73% during the 2014-2015 season. Influenza C detections occurred among patients of all ages, with rates being similar between inpatients and outpatients. The highest rate of detection occurred among children aged 6-24 months (1.2%). Among hospitalized cases, 7 required intensive care. Medical comorbidities were reported in 58% of hospitalized cases and all who required intensive care. At least 1 other respiratory pathogen was detected in 40 (66%) cases, most commonly rhinovirus/enterovirus (25%) and respiratory syncytial virus (20%). The hemagglutinin-esterase-fusion gene was sequenced in 37 specimens, and both C/Kanagawa and C/Sao Paulo lineages were detected in inpatients and outpatients. We found seasonal circulation of influenza C with year-to-year variability. Detection was most frequent among young children but occurred in all ages. Some cases that were positive for influenza C, particularly those with comorbid conditions, had severe disease, suggesting a need for further study of the role of influenza C virus in the pathogenesis of respiratory disease.

    To evaluate the etiology and the clinical outcomes of secondary surgical interventions for dissatisfied patients after pseudophakic monovision. Department of Ophthalmology, Kitasato University Hospital, Kanagawa, Japan. Retrospective case series. This study comprised 12 eyes in 12 patients (age 66.2 ± 5.6 years) who underwent photorefractive keratectomy (PRK) enhancement to improve their dissatisfaction after pseudophakic monovision. We quantitatively assessed the visual and refractive outcomes and the subjective satisfaction measured using a visual analog scale, that ranged from 0 (very dissatisfied) to 10 (very satisfied), before and 3 months after PRK enhancement. Six (50%) of the 12 patients were dissatisfied with their various distance visions because of a large amount of anisometropia (≥2.50 D). Two (16.7%) were dissatisfied with their distance vision after conventional monovision because of residual cylindrical errors (≥0.75 D) in the dominant eye. Three (25%) was an unknown origin. The remaining one of the 12 patients was dissatisfied due to the unadaptability to crossed monovision. Eleven (91.7%) eyes were within ±0.5 D of the targeted correction after PRK enhancement. The overall satisfaction score was significantly improved, from 3.7 ± 2.4 (range 0-7) preoperatively to 6.0 ± 2.4 (range 2-9) postoperatively (p = 0.02). No vision-threatening complications were seen throughout the observation period. PRK enhancement was effective with predictable refractive results and thus improved patient satisfaction for dissatisfied patients after pseudophakic monovision. These findings also suggest that the accurate correction of refractive errors plays a key role in successful pseudophakic monovision.

    To evaluate the relationship between ocular deviation and stereopsis and fusion in patients who had pseudophakic monovision surgery. Department of Ophthalmology, Kitasato University Hospital, Kanagawa, Japan. Retrospective comparative case series. Patients had surgical monovision correction with monofocal intraocular lens placement followed by routine postoperative examinations. The alternate prism cover test was used to measure motor alignment. Sensory tests for binocularity included sensory fusion determinations using the Worth 4-dot test, near stereopsis test, and fusion amplitude measured with a prism bar. Patients with monovision were categorized as having small-angle exophoria (≤10.0 prism diopters [Δ]) or moderate-angle exophoria (>10.0 Δ). This study comprised 60 patients with a mean age of 70.2 years ± 7.7 (SD). The difference in the mean stereopsis values between patients with small-angle exophoria and patients with moderate-angle exophoria was statistically significant (P<.001). In the moderate-angle exophoria group, 10 patients (62.5%) developed intermittent exotropia after surgery; however, no serious ocular deviation problems were observed. The fusion amplitudes in patients with pseudophakic monovision were approximately similar to normal values. Patients with moderate-angle exophoria were more likely to fail the Worth 4-dot test than those with small-angle exophoria. In patients with pseudophakic monovision having a near exophoria angle of more than 10.0 Δ, the possibility of changes in ocular deviation and stereopsis after surgery is a concern. Moreover, the application of monovision in patients with a previous moderate-angle exophoria should be carefully considered.

    Full Text Available Context: Various studies have focused on the correlation between β2-adrenergic receptor (β2AR, the β3-adrenergic receptor (β3AR, and the uncoupling protein 1 (UCP1 polymorphisms and obesity in patients with type 2 diabetes mellitus (T2DM. Aims: We examined the correlation between these polymorphisms and body composition variables and between body composition and lifestyle variables in Japanese T2DM patients. Materials and Methods: Of the 48, T2DM outpatients in Kanagawa prefecture recruited for participation, 32 (6 men and 26 women met the study criteria and were enrolled. Obesity-related gene polymorphisms were identified in 3 genes β3AR, UCP1, and β2AR using the SMart amplification process. Body composition variables were measured using a body composition analyzer. Data regarding food and nutrient consumption, family history, and lifestyle factors were collected via administration of questionnaires. Results: Because significant differences in body composition variables were found between men and women, statistical analysis was performed with data from the 25 female subjects only. On the basis of results of genetic testing, the subjects were divided into genotype groups for two-group and three-group comparison. The β3AR, UCP1, and β2AR polymorphisms and body composition significantly correlated with the percentage of subcutaneous fat in both arms as compared with the wild type or hetero groups with β3AR polymorphisms. However, physical activity correlated with several body composition variables. Conclusions: These results suggest that obesity in T2DM patients is not the result of presence of an obesity-related gene polymorphism but rather the absence of daily physical activity.

Endolaser photocoagulation and silicone oil tamponade were used to manage inferior retinal holes. Four weeks after the surgery, she returned with a 5-day history of reduced vision and metamorphopsia in her left eye. Slit-lamp examination showed a shallow anterior chamber in the right eye and moderate anterior uveitis bilaterally. Silicone oil bubbles and pigment dispersion were observed in the subconjunctival space adjacent to the right eye’s superonasal sclerotomy site. Fundus examination showed multifocal serous retinal detachments in both eyes. A diagnosis of sympathetic ophthalmia was made and the patient was treated with intensive topical and systemic steroids. The subretinal fluid cleared in both eyes following treatment. Twelve months after the onset of inflammation, the patient’s condition was stable on a combination of oral cyclosporine and topical steroids. Sunset glow retinal changes remain, but there has been no evidence of recurrent inflammation.Conclusion: Sympathetic ophthalmia can develop after 23-gauge

Materials and methods: We used polymerase chain reaction amplification with sequencespecific primers to analyze 20 polymorphic microsatellite markers in and around the GPDS1 locus with an automated DNA analyzer and automated fragment detection by fluorescent-based technology. The DNA samples used for these analyses were obtained from ethnicity- and gendermatched patients, including 141 Japanese patients with NTG and 101 healthy controls. Patients exhibiting a comparatively early onset were selected as this suggests that genetic factors may show stronger involvement.Results: One allele of D7S2462 exhibited a frequency that was significantly decreased in NTG cases compared to controls (P = 0.0013, Pc = 0.019, OR = 0.48, 95% CI = 0.30–0.75. Alleles at another six microsatellite loci were positively or negatively associated with NTG, but these associations did not retain statistical significance after Bonferroni correction (P < 0.05, Pc > 0.05.Conclusion: Our study showed a significant association between the GPDS1 locus and NTG, suggesting that there may be some genetic risk factor(s in the development of NTG.Keywords: microsatellite, normal tension glaucoma, glaucoma-related pigment dispersion syndrome, GPDS1, DPP6

    Proteus mirabilis is a common cause of urinary tract infection. Wild-type P. mirabilis strains are usually susceptible to penicillins and cephalosporins, but occurrences of P. mirabilis producing extended-spectrum β-lactamases (ESBLs) have been recently reported. Here, we surveyed the prevalence of cefotaxime resistance among P. mirabilis strains at seven different hospitals in Kanagawa Prefecture, Japan, and investigated their molecular epidemiology to explain the mechanism of their spread. The prevalence of cefotaxime resistance among P. mirabilis increased annually, from 10.1 % in 1998 to 23.1 % in 2003, and increased drastically in 2004, exceeding 40 %. We collected 105 consecutive and non-duplicate cefotaxime-resistant P. mirabilis isolates (MIC 16 to >256 µg ml(-1)) from these hospitals from June 2004 to May 2005 and characterized their profile. PCR and sequence analysis revealed that all resistant strains produced exclusively CTX-M-2 β-lactamase. PFGE analysis identified 47 banding patterns with 83 % or greater similarity. These results indicated that a regional outbreak of P. mirabilis producing CTX-M-2 β-lactamase has occurred in Japan and suggest that the epidemic spread occurred within and across hospitals and communities by extended clonal strains. Plasmid analysis revealed that 44.8 % of plasmids harboured by bla(CTX-M-2) isolates had common profiles, encoding ISEcp1, IS26 and Int1, and belonged to incompatibility group T. Spread of the resistant isolates in Japan resulted from dissemination of narrow-host-range plasmids of the IncT group encoding bla(CTX-M-2). These findings indicate the rapidly developing problem of treating the species to prevent dissemination of ESBL producers.

    Nonoperative management (NOM) of hepatic injuries caused by blunt trauma in hemodynamically stable patients is widely accepted, but the feasibility of NOM for severe hepatic injuries has not been fully evaluated. Among all patients with blunt severe hepatic injury (type IIIb) admitted to Saiseikai Kanagawa-ken Hospital and Keio University Hospital from 1988 to 2004, those who had been hemodynamically stable after fluid resuscitation at the emergency department were initially managed nonoperatively. We reviewed demographic, physiological, and laboratory data; computed tomography (CT) findings; 80-day cumulative laparotomy rate; and complications. The anatomical severity of the hepatic injuries was evaluated based on the CT findings, such as hepatic vein injuries and area lacerated according to the Couinaud liver segment. In patients who underwent surgery after admission, the surgical indications and operative findings were reviewed. Overall, 34 consecutive patients were enrolled in this study. Five patients underwent surgery, and all of their surgical indications were attributable to liver-related complications after injury. The indication for surgery was hemodynamic instability in 3 patients with hepatic vein injures in the early phase (<15 hours after estrogen receptor (ER) arrival) and intra-abdominal septic complications in 2 patients in the late phase (hospital days 14 and 64). The cumulative 80-day laparotomy rate in the early phase was significantly higher (p<0.0001) in the patients suspected of having hepatic vein injury, and in the late phase it was higher (p=0.002) in those with injuries in 4 or more segments of hepatic injuries. For the successful NOM of blunt hepatic injury type IIIb in patients who are hemodynamically stable after fluid resuscitation, a strong suspicion of concurrent hepatic vein injury is critical in the early phase, and laceration in 4 or more segments should be noted in the late phase.

    To estimate the change in health-promoting activities among elderly people affected by community organizing environments, we examined the relationships among health-promoting activity, going out and perceived transportation problems. A questionnaire was sent to 567 men and women aged 60 years old and over living in a small town in Kanagawa prefecture between July 27 and August 12 in 1995. The questionnaire consisted of 42 items concerning health, social ability of daily living (including the desire to participate in social activities), attitude toward health-promoting activities, and perceived transportation problems. A total of 397 people responded and the answers from 368 people were analyzed after excluding responses from those unable to go out by themselves and those who seldom went out. Single regression analysis and multiregression analysis were used with the sum of responses for each question representing factors related to health-promoting behavior. A probability level of 5 percent was considered significant. The reliability of the data was examined with Cronbach's coefficient alpha. Coefficients of determination for health promoting behavior were 42% in men and 48% in women. In both men and women, age, social ability of daily living and attitudes toward health-promoting behavior were related to health-promoting activity. In women, more actively going out was related to more active health-promoting activity. Higher perception of transportation problems had a negative effect on going out. In men, neither of these factors had any relationship with health-promoting activity. In men, poorer health conditions were related to more active health-promoting activity, but in women, there was no relationship between those factors. These results show that there are gender differences in the relationships among the factors related to health-promoting activities in elderly people. In women, a higher perception of transportation problems restrained actively going out and

  9. Dietary compositions and their seasonal shifts in Japanese resident birds, estimated from the analysis of volunteer monitoring data.

    Full Text Available Determining the composition of a bird's diet and its seasonal shifts are fundamental for understanding the ecology and ecological functions of a species. Various methods have been used to estimate the dietary compositions of birds, which have their own advantages and disadvantages. In this study, we examined the possibility of using long-term volunteer monitoring data as the source of dietary information for 15 resident bird species in Kanagawa Prefecture, Japan. The data were collected from field observations reported by volunteers of regional naturalist groups. Based on these monitoring data, we calculated the monthly dietary composition of each bird species directly, and we also estimated unidentified items within the reported foraging episodes using Bayesian models that contained additional information regarding foraging locations. Next, to examine the validity of the estimated dietary compositions, we compared them with the dietary information for focal birds based on stomach analysis methods, collected from past literatures. The dietary trends estimated from the monitoring data were largely consistent with the general food habits determined from the previous studies of focal birds. Thus, the estimates based on the volunteer monitoring data successfully detected noticeable seasonal shifts in many of the birds from plant materials to animal diets during spring-summer. Comparisons with stomach analysis data supported the qualitative validity of the monitoring-based dietary information and the effectiveness of the Bayesian models for improving the estimates. This comparison suggests that one advantage of using monitoring data is its ability to detect dietary items such as fleshy fruits, flower nectar, and vertebrates. These results emphasize the potential importance of observation data collecting and mining by citizens, especially free descriptive observation data, for use in bird ecology studies.

These isolates were divided into three clusters, namely: CSFV-1, CSFV-2, and CSFV-3, based on palindromic nucleotide substitutions in the 5’ untranslated region (UTR. The homology degree, according to nucleotide base pairing variation in the secondary palindromic structure of the three variable loci V1, V2 and V3, was 60% in the CSFV species, with a mean divergence value of 6.19 base pairs (bp. relatedness within genotypes ranged from 71.11% to 100%, with mean divergence values from 5.5 to 0.73 base pairs. Subgenotypes showed a divergence ranging from 1 to 9 base pairs within the genotype. Genotype CSFV-1 revealed 15 base pair combinations with 13 divergent base pairs, resulting in 4 subgenotypes with 6 variants in subgenotype CSFV-1.1, including the reference strain Brescia and 6 variants in subgenotype CSFV-1.2, including the Alfort reference strain. Subgenotypes CSFV-1.3 and CSFV-1.4 comprised one and two variants, respectively. Genotype CSFV-2 was represented by the Spanish ovine isolate 5440/99 and the genotype CSFV-3 included the Japanese strains Okinawa/86 and Kanagawa/74. CSFV genotypes revealed a strong relationship with Border disease virus strains, showing relatively low divergence values when compared to other pestivirus species. Evaluation of nucleotide base pair divergence among genotypes and expression of evolutionary changes in the CSFV species led to the construction of a phylogenetic tree based on secondary structure.

However, the incidence of PVD has not been well documented. This study aimed to investigate the incidence of dizziness, vertigo, and PVD among patients presenting at a primary care clinic. Design: This was an observational study. Setting and participants: Between November 2011 and March 2013, we observed 393 patients, all at least 20 years old, who had been treated for chronic diseases such as hypertension, dyslipidemia, and diabetes mellitus for at least 6 months at a primary clinic (Oki Clinic in Japan. Outcome: The main outcome of interest was new incidence of dizziness, vertigo, and PVD events. During the 1-year follow-up period, the otorhinolaryngologist diagnosed and reported new PVD events. Results: The mean age of the 393 participants at entry was 65.5 years. Of the study participants, 12.7%, 82.4%, and 92.6% had diabetes mellitus, hypertension, and dyslipidemia, respectively. We followed up all the participants (100%. During the 662.5 person-years of follow-up, 121 cases of dizziness or vertigo (dizziness/vertigo and 76 cases of PVD were observed. The incidence of dizziness/vertigo and PVD was 194.7 (95% confidence interval: 161.6–232.6 per 1,000 person-years and 115.7 (95% confidence interval: 92.2–142.6 per 1,000 person-years, respectively.

The stability of GZ-DE was estimated from residual GZ-DE and GZ produced in GZ-DE solutions prepared with distilled water, a pH 1.2 solution, 0.9% NaCl solution, and phosphate-buffered solution (pH 7.4 at 37°C.Results: GZ-DE was eliminated into bile by the pharmacokinetic parameters of apparent distribution rate constant (4.56 ± 0.36 per hour and apparent elimination rate constant (0.245 ± 0.042 per hour. After intravenous and intraduodenal administration of GZ-DE, the concentration ratio of GZ-DE to GZ in bile was approximately 4:1, and the bioavailability of GZ containing GZ-DE was three-fold higher compared with the bioavailability of GZ after intraduodenal administration. GZ-DE was immediately precipitated in pH 1.2 solution and was converted to GZ by hydrolysis in pH 7.4 solution.Conclusion: Improvement of intestinal absorption of GZ was made possible by administration of GZ-DE into the intestine where absorption of GZ is lower than in the strong acidic environment of the stomach. However, because the elimination rate in bile simulated from kinetic parameters of GZ-DE was higher than the conversion rate from GZ-DE to GZ by hydrolysis, it is thought that the availability of GZ as a revolutionary prodrug was not high from the

Methods: Ex-PRESS insertion was performed in 21 eyes and standard trabeculectomy (TLE in 22 eyes. Mean intraocular pressure (IOP in the 6 months after surgery, success rate for postoperative IOP decline, postoperative complications, postoperative treatment, filtering blebs, and indications were then retrospectively investigated. Results: Mean postoperative IOP did not differ significantly between the groups at any observation time for 6 months after surgery. Further, it did not differ between either the groups of patients with primary open-angle glaucoma (POAG and neovascular glaucoma (NTG, or the patients with primary open-angle glaucoma and NTG in the Ex-PRESS group. Comparison of success rates in reduction of postoperative IOP between the groups under the following four survival conditions showed no significant differences: postoperative IOP <30% of the preoperative IOP, complete success (no additional ophthalmic solution, and qualified success (ophthalmic solution required; 5 mmHg ≤ postoperative IOP ≤21 mmHg, complete success (no additional ophthalmic solution, and qualified success (ophthalmic solution required. With regard to postoperative complications and postoperative treatment, the incidence of hyphema was significantly lower in the Ex-PRESS group, but no other significant intergroup differences were seen. The height of the filtering bleb was lower in the Ex-PRESS group. Conclusion: Postoperative outcomes in the Ex-PRESS and TLE groups were comparable. The incidence of hyphema was significantly lower in the Ex-PRESS group. Ex-PRESS insertion

The purpose of the present anatomical study was to better elucidate the anatomy and improve the understanding of “pseudo-sciatica” from SCN entrapment. Materials and methods: SCN branches were dissected from their origin to termination in subcutaneous tissue in 16 cadavers (5 male and 11 female with a mean death age of 88 years (range 81–101 years. Special attention was paid to identify SCNs from their emergence from nerve roots and passage through the fascial attachment to the iliac crest. Results: Eighty-one SCN branches were identified originating from T12 to L5 nerve roots with 13 branches passing through the osteofibrous tunnel. These 13 branches originated from L3 (two sides, L4 (six sides, and L5 (five sides. Ten of the 13 branches showed macroscopic entrapment in the tunnel. Conclusion: The majority of SCNs at risk of nerve entrapment originated from the lower lumbar nerve. These anatomical results may explain why patients with SCN entrapment often evince leg pain or tingling that mimics sciatica. Keywords: superior cluneal nerve, entrapment neuropathy, dorsal rami

During 5 years of follow-up, we therefore investigated the efficacy and safety of PPV for BRVO and evaluated the incidence of additional treatments. Methods: We retrospectively reviewed the medical records of 25 eyes of 24 patients who underwent PPV for ME associated with BRVO and were followed up for at least 5 years. Best-corrected visual acuity was measured, and foveal thickness was assessed by optical coherence tomography. Additional treatments were also investigated. Results: The logarithm of the minimal angle of resolution (logMAR improved from 0.53±0.23 at baseline to 0.16±0.25 at 5 years (P<0.0001. The foveal thickness decreased from 535±222 µm at baseline to 205±143 µm at 5 years (P<0.0001. For the eyes with residual ME, the following additional treatments were performed within 5 years of follow-up: sub-Tenon injection of triamcinolone acetonide in two eyes, intravitreal injection of bevacizumab in three eyes, grid laser photocoagulation in one eye, and direct photocoagulation of macroaneurysm in one eye. Additional surgeries were performed in two eyes: for one eye, phacoemulsification extraction of the ocular lens and intraocular lens implantation were performed because of cataract progression, and for the other eye, additional PPV was done for postoperative retinal detachment. Conclusion: PPV was effective for resolution of ME

Several studies have shown that hangeshashin-to (TJ-14 might be useful for chemotherapy-induced diarrhea and oral mucositis. In this study, we investigated the prophylactic effects of TJ-14 for afatinib-induced diarrhea and oral mucositis and minocycline for afatinib-induced skin rash.Patients and methods: First- and second-generation epidermal growth factor receptor (EGFR-tyrosine kinase inhibitors have become the standard first-line treatment in patients with EGFR-mutated non-small cell lung cancer. The incidence of diarrhea was higher with afatinib than with gefitinib, and we conducted a single-arm Phase II study with afatinib. Patients who had previously undergone treatment with afatinib were ineligible. Both TJ-14 (7.5 g/day and minocycline (100 mg/day were administered simultaneously from the start of afatinib administration. The primary end point was the incidence of ≥ grade 3 (G3 diarrhea (increase of ≥7 stools/day over baseline during the first 4 weeks of treatment. The secondary end points were the incidence of ≥ G3 oral mucositis (severe pain interfering with oral intake and ≥ G3 skin toxicity (severe or medically significant but not immediately life-threatening.Results: A total of 29 patients (nine men and 20 women; median age, 66

We prepared a database covering young-mature adulthood and investigated the clinical usefulness of the evaluation. Subjects and methods: One hundred seven patients with major depressive disorder (MDD, 74 patients with bipolar disorder (BD, and 240 healthy control subjects underwent 1.5T magnetic resonance imaging scanning. Using new VBM software and databases covering young-mature adults and the elderly, target volumes of interest were set in the sgACC and scACC, four indicators (severity, extent, ratio, and whole-brain extent were determined, and the presence or absence of atrophy of the sgACC and scACC was evaluated on the basis of the indicators. In addition, the relationships between the presence or absence of atrophy of the sgACC and scACC and performance of diagnosing MDD and BD and therapeutic drugs were investigated. Results: It was clarified that the disease is likely to be MDD when atrophy is detected in the sgACC, and likely to be BD when no atrophy is detected in the sgACC but is detected in the scACC. Regarding the relationship with therapeutic drugs, it was clarified that, when

With aflibercept treatment, treatment-naïve eyes with a good response/non-dependence were recommended a pro re nata regimen, and other eyes were recommended a proactive bimonthly regimen, followed by monitoring of visual acuity (VA for 12 months. The measured values of the groups were compared using one-way analysis of variance with Tukey’s test to evaluate the difference between baseline and postinjection VA.Results: Among the treatment-naïve eyes, 76% had a good response to aflibercept and 37% of these were aflibercept-dependent, while 58% had a good response to ranibizumab but 51% of these were ranibizumab-dependent. Among the eyes that converted from ranibizumab treatment, 92% of the good responders to ranibizumab with dependence and 76% of the poor responders on ranibizumab had a good response to aflibercept. With aflibercept treatment, the mean VA of treatment-naïve patients was significantly better than the baseline VA over 12 months (P<0.001, and the VA of the converted group improved significantly with proactive treatment and the improvement was continuously maintained from 6 to 12 months

We performed LSA at 7 points to examine whether the technique could identify the location of airway inflammation in patients with asthma. Patients and methods: Breath sounds were recorded at 7 points on the body surface of 22 asthmatic subjects. Inspiration sound pressure level (ISPL, expiration sound pressure level (ESPL, and the expiration-to-inspiration sound pressure ratio (E/I were calculated in 6 frequency bands. The data were analyzed for potential correlation with spirometry, airway hyperresponsiveness (PC20, and fractional exhaled nitric oxide (FeNO. Results: The E/I data in the frequency range of 100–400 Hz (E/I low frequency [LF], E/I mid frequency [MF] were better correlated with the spirometry, PC20, and FeNO values than were the ISPL or ESPL data. The left anterior chest and left posterior lower recording positions were associated with the best correlations (forced expiratory volume in 1 second/forced vital capacity: r=–0.55 and r=–0.58; logPC20: r=–0.46 and r=–0.45; and FeNO: r=0.42 and r=0.46, respectively. The majority of asthmatic subjects with FeNO ≥70 ppb exhibited high E/I MF levels in all lung fields (excluding the trachea and V50%pred <80%, suggesting inflammation throughout the airway. Asthmatic subjects with FeNO <70 ppb showed high or low E/I MF levels depending on the recording position, indicating uneven airway inflammation. Conclusion: E/I LF and E/I MF are more useful LSA parameters for evaluating airway inflammation in bronchial asthma; 7-point lung

We measured static, kinetic, and dynamic visual acuity (SVA, KVA, and DVA, respectively of Japanese professional baseball players to ascertain whether there would be any difference in SVA, KVA, and DVA among player groups stratified according to their performance level. Methods: The subjects were 102 male professional baseball players with a mean age of 26 years who were members of a Japanese professional baseball club from 2000 to 2009. They were stratified into three groups according to their performance level: A (players who were on the roster of the top-level team all the time throughout the study period, B (players who were on the roster of the top-level team sometimes but not all the time, and C (players who were never on the roster of the top-level team. They were interviewed for the use of corrective visual aids, and examined for SVA, KVA, and DVA. The measurements of these parameters were compared among groups A, B, and C. We also investigated and analyzed the association of KVA or DVA with player position (pitchers or fielders and with hand dominance for batting. KVA was compared between the pitchers and the fielders because they each require different playing skills. DVA was compared between the right-handed and the left-handed batters. Results: There was no statistically significant difference among groups A, B, and C. There was a statistically significant difference in

Coinfusion of dexamethasone and oxaliplatin could potentially reduce the incidence of these reactions, but oxaliplatin is reported to be incompatible with alkaline compounds in solution. However, in a previous retrospective study we found that the pH of a solution of dexamethasone and oxaliplatin was less than 7.4, and that hypersensitivity to oxaliplatin could have been prevented by coinfusion of dexamethasone.

    Full Text Available The paper addresses prospects of Japanese mobile telepresence robotics where small anthropomorphic devices are designed to act as intermediaries between remote interlocutors. First, an emic perspective of involved scientists and engineers is presented, focusing on example technologies being developed at the Hiroshi Ishiguro Lab in Kyoto (Japan, particularly a „cellphone-type tele-operated android [...] transmitting human presence“ called Elfoid. It represents an attempt to get “behind the veil of the machine” (Sekiguchi/Inami/Tachi 2001, about their RobotPHONE prototype which uses a similar concept in that it is supposed to act as a solid substitute for a dialog partner through evoking a feeling of presence (sonzaikan in Japanese philosophy, the feeling that someone is sharing the same physical space. In such undertakings, specific utopian ideals of communication become apparent. Paradoxically, the high-tech developments aim at constituting seemingly immediate interactions, preferably bypassing any potentially troublesome interface. The existence of a phantasm of immediacy (Bolter/Grusin 2000 can be traced back to decisive moments in media history and belongs to the central promises of new technological interfaces. Interestingly, the engineers’ statements reveal a latent technophobia, an ambition to overcome the limitations of physical devices altogether and to move on to more direct means of communicative exchange (including the mythical dimension of telepathy. Two questions are of particular concern: 1. On what different levels does the notion of immediacy operate? Not only does it refer to a spiritual ideal of unmediated communion, but it also influences practical decisions in interface design. “Natural” and “Tangible” User Interfaces are the result of a practice of disguise in that they mask their factual hypermediacy to allow for a seamless knotting up of real and mediated environments. 2.

The safety of tipepidine in children and adults has already been established. It is reported that tipepidine inhibits G-protein-coupled inwardly rectifying potassium (GIRK-channel currents. The inhibition of GIRK channels by tipepidine is expected to modulate the level of monoamines in the brain. We put forward the hypothesis that tipepidine can improve attention deficit/hyperactivity disorder (ADHD symptoms by modulating monoaminergic neurotransmission through the inhibition of GIRK channels. The purpose of this open-label trial was to confirm whether treatment with tipepidine can improve symptoms in pediatric patients with ADHD.Subjects and methods: This was a 4-week, open-label, proof-of-efficacy pilot study for pediatric subjects with ADHD. Ten pediatric ADHD subjects (70% male; mean age, 9.9 years; combined [inattentive and hyperactive/impulsive] subtype, n=7; inattentive subtype, n=3; hyperimpulsive subtype, n=0 received tipepidine hibenzate taken orally at 30 mg/day for 4 weeks. All subjects were assessed using the ADHD Rating Scale IV (ADHD-RS, Japanese version, and the Das–Naglieri Cognitive Assessment System (DN-CAS, Japanese version.Results: A comparison of baseline scores and 4-week end-point scores showed that all the ADHD-RS scores (total scores, hyperimpulsive subscores, and inattentive subscores

    The Proceedings As co-chairs of the 9th International Symposium on Display Holography, we welcome readers of this collection of papers and posters presented at the event. We hope that both attendees of the event and others pursuing the art, science, and business of holography and 3D imaging will find the authors' contributions of lasting interest and importance. The Event Since its creation at Lake Forest College in 1982 by Professor Tung H Jeong, ISDH has followed a model that differentiates it from other scientific conferences. The 9th ISDH continued this history, fully occupying a floor of the MIT Media Lab for five days. The single-track conference opened with reports on the state of holography in the various nations represented by the attendees, followed by a series of presentations on Education and Holography. One and one-half days of papers on Art and Holography followed, then sessions on Techniques and Materials, Digital Techniques, and Commercial and Applied Holography. A poster session permitted more in-depth discussion between authors and the audience. Two exhibitions of holographic works opened at ISDH: an informal display area at the symposium, and a 15-month-long MIT Museum exhibition, The Jeweled Net: Views of Contemporary Holography. The success of an event of this sort requires the help of many people and organizations. We wish especially to recognize our Honorary Conference Chairs: Tung H Jeong and Joseph W Goodman; our Technical Program Committee: Hans I Bjelkhagen, Frank Fan, Nasser Peyghambarian, and Hiroshi Yoshikawa; and our Arts and Exhibition Committee: Betsy Connors-Chen, Melissa Crenshaw, John Durant, Dieter Jung, Linda Law, Martin Richardson, Jonathan Ross, and Sally Weber. Betsy also coordinated the on-site exhibition. Kristin Hall at the MIT Media Lab made local arrangements, while registration was handled by MIT Conference Services.

The purpose of this study was to investigate a cutoff point for skin hydration with fissure and the factors associated with low skin hydration in patients with diabetes. Subjects and methods: Subjects were patients with diabetes who visited the diabetic foot clinic and were evaluated for skin hydration on the heel between April 2008 and March 2015. Information about fissure, skin hydration, age, sex, autonomic neuropathy, angiopathy, and tinea pedis were collected from the medical charts. Skin hydration on the heel was measured using a moisture checker. Skin hydration was compared between heels with and without fissure, and a cutoff for skin hydration with fissure was determined using receiver operating characteristic analysis. Based on the determined cutoff, factors associated with lower skin hydration were analyzed using logistic regression analysis. Results: Participants comprised 693 patients. Mean±SD age was 66.8±10.8 years, and 57.0% of subjects were male. The frequency of fissures on the heels was 10.4%. Area under the receiver operating characteristic curve for skin hydration in the presence of fissure was 0.717. Twenty percent was selected as the cutoff point, offering sensitivity of 0.478 and specificity of 0.819. Logistic regression analysis showed correlations between three factors (male sex, tinea

    Full Text Available Hiroshi Nakagawa,1 Akio Hiura2 1Dentistry for Persons with Disability, Tokushima University Hospital, Tokushima, Japan; 2Department of Oral Histology, School of Dentistry, University of Tokushima, Tokushima, Japan Background: It has been demonstrated that N-ethyl-lidocaine (QX-314 can target the transient receptor protein vanilloid 1 (TRPV1 nociceptors when coadministered with capsaicin, resulting in a selective block of the nociceptors. Capsaicin is problematic in therapeutic use because it induces firing of nociceptors. The present study aimed to search for substitutes for capsaicin. We also examined the transportability of QX-314 into nociceptive neurons, through the pores of transient receptor potential ankyrin 1 (TRPA1, transient receptor potential melastatin-8 (TRPM8, and TRPV1. Methods: To investigate the effect on TRPA1, injections of a vehicle, allyl isothiocyanate (AITC, QX-314, or AITC/QX-314 were made into the hind paws of rats. The effects of menthol and capsaicin on the opening of TRPM8 and TRPV1 were also examined and compared with the potency of QX-314. To examine inhibition of the antinociceptive effect by capsaicin/QX-314, capsazepine (50 µg/mL; 10 µL was injected 30 minutes prior to capsaicin/QX-314 (10 µL injection. Thermal sensitivity was investigated by the Hargreaves method. 5(6-carboxyfluorescein (FAM-conjugated QX-314 was used as a tracer to examine how many and which kind of dorsal root ganglia accumulate this molecule. QX-314-FAM, capsaicin/QX-314-FAM, AITC/QX-314-FAM, and menthol/QX-314-FAM were injected into the paw. Two weeks after injections, dorsal root ganglia were removed and sectioned with a cryostat. Results: The capsaicin/QX-314 group induced longer withdrawal-response latency at 60 to 300 minutes after injection than the control. Both menthol only and menthol/QX-314 injections showed analgesia 10 to 60 minutes after injection. No significant difference was seen between the capsazepine/capsaicin/QX-314

Dementia is a major brain disease among elderly people, and is caused by cognitive impairment. The locomotive syndrome (LS refers to a condition in which people require healthcare services because of problems associated with locomotion. The purpose of this study was to determine the association between cognitive impairment and LS. Study participants were 142 healthy elderly female volunteers living in a rural area in Japan. Cognitive function was assessed using the Mini-Mental State Examination (MMSE. A score of ≤26 points on the MMSE was used to indicate categorically defined poor cognitive performance (cognitive impairment. The LS was defined by a score ≥16 points, and non-LS as <16 points, on the 25-question Geriatric Locomotive Function Scale (GLFS-25. Twenty-one participants (14.8% had an MMSE score ≤26, and 19.0% were found to have LS. Compared with the MMSE >26 group, the ≤26 group was significantly older, had a higher percentage of body fat, and a higher GLFS-25 score. Those with LS were significantly older, had a higher body mass index, a higher percentage of body fat, and a lower MMSE score. Participants in the LS group had higher odds of cognitive impairment than those without LS [odds ratio (OR =3.08] by logistic regression analysis adjusted for age. Furthermore, participants with GLFS-25 scores ≥6 had higher odds of cognitive impairment than those with a GLFS-25 score <6 by logistic regression analysis adjusted for both age (OR =4.44, and age and percent body fat (OR =4.12.

Although combined multiple causes of intractable pruritus in these patients have been identified, no existing treatments are proven to be sufficiently effective. We conducted a post-marketing surveillance to follow-up and assess the safety and efficacy of nalfurafine, a selective κ-opioid receptor agonist, for the treatment of intractable pruritus in patients undergoing hemodialysis. Patients and methods: Hemodialysis patients with intractable pruritus from institutions in Japan who received oral nalfurafine hydrochloride between January 2010 and December 2013 were enrolled in the surveillance. Surveillance was completed in July 2015. Safety data during 1 year after nalfurafine treatment onset, and efficacy data of nalfurafine evaluating the first 12-week treatment period and the following period until 1 year after the initial dose of nalfurafine (using global assessment of the itch improvement by the physician, Visual Analog Scale, and the Shiratori’s severity scores were collected and analyzed. Results: In total, 3,762 patients were analyzed for safety. Adverse drug reactions were experienced by 402/3,762 (10.69% patients. The most frequent adverse drug reactions were insomnia (127/3,762 [3.38%] patients, constipation (34 [0.90%], somnolence (32 [0.85%], dizziness (23 [0.61%], nausea (13 [0.35%], and malaise (9 [0.24%].

However, little evidence of the efficacy of nonpharmacological interventions for agitated behaviors exists for patients with dementia. The present pilot study aimed to evaluate a behavioral management program developed by the Seattle Protocols for patients with agitated behaviors in Japan.Methods: Eighteen patients with dementia (Alzheimer’s disease, n = 14; dementia with Lewy bodies, n = 4 participated in an open study testing the effectiveness of a behavioral management program. The intervention consisted of 20 sessions over the course of 3 months. The primary outcomes were severity of agitation in dementia, as measured using the Agitated Behavior in Dementia scale (ABID and the Cohen-Mansfield Agitation Inventory (CMAI.Results: The behavioral management program resulted in significant reductions in total scores on both the ABID and CMAI. Although both physically agitated and verbally agitated behavior scores on the ABID improved significantly, symptoms of psychosis did not improve after the intervention.Conclusion: The behavioral management technique may be beneficial to distressed caregivers of

We speculated that forcible maximum opening of the mouth by using a mouth prop triggers this asphyxia by affecting the upper airway. Therefore, we assessed the morphological changes of the upper airway following maximal opening of the mouth. In 13 healthy adult volunteers, the sagittal diameter of the upper airway on lateral cephalogram was measured between the two conditions; closed mouth and maximally open mouth. The dyspnea in each state was evaluated by a visual analog scale. In one subject, a computed tomograph (CT was taken to assess the three-dimensional changes in the upper airway. A significant difference was detected in the mean sagittal diameter of the upper airway following use of the prop (closed mouth: 18.5 ± 3.8 mm, maximally open mouth: 10.4 ± 3.0 mm. All subjects indicated upper airway constriction and significant dyspnea when their mouth was maximally open. Although a CT scan indicated upper airway constriction when the mouth was maximally open, muscular compensation was admitted. Our results further indicate that the maximal opening of the mouth narrows the upper airway diameter and leads to dyspnea. The use of a prop for the patient who has communication problems or poor neuromuscular function can lead to asphyxia. When the prop is used for patient refusal in dentistry, the respiratory condition should be monitored strictly, and it should be kept in mind that the “sniffing position” is effective for avoiding upper airway

We considered that observation with different approaches may provide new insights for the pathogenesis of emphysema. Patients and methods: We reviewed tissue blocks of the lungs of 25 cases with/without emphysema and applied a three-dimensional observation method to the blocks. Based on the three-dimensional characteristics of the alveolar structure, we considered one face of the alveolar polyhedron as a structural unit of alveoli and called it a framework unit (FU. We categorized FUs based on their morphological characteristics and counted their number to evaluate the destructive changes in alveoli. We also evaluated the number and the area of pores of Kohn in FUs. We performed linear regression analysis to estimate the effect of these data on pulmonary function tests. Results: In multivariable regression analysis, a decrease in the number of FUs without an alveolar wall led to a significant decrease in the diffusing capacity of the lung for carbon monoxide (DLCO and DLCO per unit alveolar volume, and an increase in the area of

Although the ultimate outcome remains uncertain, functional and morphological brain changes are not uncommon in patients with this syndrome, and generally persist even after resolution of hypercortisolemia. We present an adolescent patient with Cushing’s syndrome who exhibited cognitive impairment with brain atrophy. A 19-year-old Japanese male visited a local hospital following 5 days of behavioral abnormalities, such as money wasting or nighttime wandering. He had hypertension and a 1-year history of a rounded face. Magnetic resonance imaging (MRI revealed apparently diffuse brain atrophy. Because of high random plasma cortisol levels (28.7 µg/dL at 10 AM, he was referred to our hospital in August 2011. Endocrinological testing showed adrenocorticotropic hormone-independent hypercortisolemia, and abdominal computed tomography demonstrated a 2.7 cm tumor in the left adrenal gland. The patient underwent left adrenalectomy in September 2011, and the diagnosis of cortisol-secreting adenoma was confirmed histologically. His hypertension and Cushingoid features regressed. Behavioral abnormalities were no longer observed, and he was classified as cured of his cognitive disturbance caused by Cushing’s syndrome in February 2012. MRI performed 8 months after surgery revealed reversal of brain atrophy, and his subsequent course has been uneventful. In summary, the young age at onset and the

The work was carried out in the laboratory of the Entomology Section of the Center of Nuclear Energy in Agriculture (CENA/USP) and in the laboratory of Biological Control of House Flies Eduardo Hiroshi Mizumoto of Entomology Department of the College of Agriculture Luiz de Queiroz (ESALQ/USP), Piracicaba, Sao Paulo, Brazil. The gamma radiation source used was a Cobalt-60 irradiator, Gamma bean-650, with an initial activity of 1,6265 x 10 4 Bq (6,746 Ci). The radiation LD 50 e LD 100 , using a dose ratio of 1457 Gy/h, for 12, 24, 36, 48, 60 and 72 hours old pupae and resulted in 15.35; 15.69; 11.30; 49.4; 142.78 and 175 Gy for LD 50 and 20, 22.5; 32.5; 175; 225 and 300 Gy for LD'1 00 respectively. Following exposure, the pupae were kept in climate chamber at 27 ± 3 0 C and 75 ± % of relative humidity, until all adults had emerged. In succession, 24, 48 and 72 hour-old pupae were exposed to gamma irradiation with a dose of 1440 Gy/hour, in their respective lethal doses. Following the exposure the pupae were stored at cool temperature (10 ± 2 0 C) for different periods of time (5, 15, 20 and 30 days). The same treatment was given for non-irradiated pupae.

    It is from February, 2002 that Deuterium Depletion Water (DDW) was imported by Japan from Hungary. Since then studies were undertaken on normal and patient Japanese subjects to observe the effect of DDW for a long period of time, and the side effects of its administration. Three types of DDW administration were undertaken and the following results are report. Normal male subject was made to consume DDW-105 ppm one liter per day, every day for one year. The stiffness of the shoulders disappeared in normal subjects men and women. The benign neoplasm disappeared. Lack of sleep sensation disappeared. The old-man skin liver spots disappeared. The male sex function was recovered. The airsickness of jet traveling abroad disappeared. In the second type of experiments a 250 liters bath of DDW-105 ppm was administrated and the normal subject was made to take a bath for 20 minutes in water temperature of 39 deg C every day for seven days in a row. The humidity effect of the skin before and after bathing, the liver spots of the skin, weight, and subjective-symptoms investigation were investigated. Side effects or changes in skin aspects were not observed after the bathing experiment. In the third case the patient was made to consume DDW-105 ppm or 25 ppm, and changes of the tumor marker following the administration were measured. In the subjects SK (Kanagawa 58 years old) who suffered from the extramammary Paget disease, it was observed that the value of the tumor marker TPA (Tissue polypeptide antigen) being 120U/L (normal value: 70U/L) at first fell to 58U/L after six months. In a case of prostatic cancer in a 64 years old HT male subject of Tokyo the tumor marker PSA (prostatic specific antigen) was 6.2 ng/ml (normal value: 4.0 ng/ml) in July, 2002. Two months after drinking DDW-105 ppm, it fell to 4.2 ng/ml. A prostatic cancer was excised and all tumor markers also reached a normal value in February, 2003. Now, subject HT consume of DDW-105 one liter every day. His face

Most titanium implants have microscale surface morphology, and an addition of nanoscale features while preserving the micromorphology may provide further biological benefit. Here, we examined the effect of ultraviolet (UV light treatment of titanium, or photofunctionalization, on the efficacy of biomimetic apatite deposition on titanium and its biological capability.Methods and results: Micro-roughed titanium disks were prepared by acid-etching with sulfuric acid. Micro-roughened disks with or without photofunctionalization (20-minute exposure to UV light were immersed in simulated body fluid (SBF for 1 or 5 days. Photofunctionalized titanium disks were superhydrophilic and did not form surface air bubbles when immersed in SBF, whereas non-photofunctionalized disks were hydrophobic and largely covered with air bubbles during immersion. An apatite-related signal was observed by X-ray diffraction on photofunctionalized titanium after 1 day of SBF immersion, which was equivalent to the one observed after 5 days of immersion of control titanium. Scanning electron microscopy revealed nodular apatite deposition

Methods: In this open-label, nondrug interventional, crossover DPI preference study comparing the ELLIPTA DPI and BREEZHALER, 150 subjects were randomized to handle the ELLIPTA or BREEZHALER DPIs until the point of inhalation, without receiving verbal or demonstrative instruction (first attempt. Subjects then crossed over to the other inhaler. Preference was assessed using a self-completed questionnaire. Inhaler handling was assessed by a trained assessor using a checklist. Subjects did not inhale any medication in the study, so efficacy and safety were not measured. Results: The ELLIPTA DPI was preferred to the BREEZHALER by 89% of subjects (odds ratio [OR] 70.14, 95% confidence interval [CI] 33.69–146.01; P-value not applicable for this inhaler for ease of use, by 63% of subjects (OR 2.98, CI 1.87–4.77; P<0.0001 for ease of determining the number of doses remaining in the inhaler, by 91% for number of steps required, and by 93% for time needed for handling the inhaler.

Age-related decreases in vagal nerve activity could contribute to orthostatic hypotension in older individuals. Fowler’s position is a reclined position with the back between 30° and 60°, used to facilitate breathing, eating, and other routine daily activities in frail and elderly patients. Objective: This study examined whether stroke volume (SV was higher and heart rate (HR lower in Fowler’s position with an upright upper trunk than in Fowler’s position with the whole trunk upright in both older and younger subjects, based on the assumption that lower HR would result from reduced sympathetic activation in older individuals. Methods: We assessed hemodynamics and HR variability from electrocardiography, noninvasive arterial pressure and impedance cardiography in 11 younger male subjects (age range, 20–22 years and 11 older male subjects (age range, 64–79 years, using three positions: supine, or Fowler’s positions with either 30° of lower trunk inclination and 60° of upper trunk inclination (UT60 or 60° of whole trunk inclination (WT60. Comparisons were then made between age groups and between positions. Results: Reductions in SV and tachycardic response were smaller with UT60 than with WT60, in both younger and older subjects. In addition, reduced tachycardic response with upright upper trunk appeared attributable to decreased vagal withdrawal in younger subjects and to reduced sympathetic activation in older subjects. Conclusion: Our findings indicate that an upright upper trunk during Fowler’s position allowed

Many previous studies reported the healing effects of Aloe vera. However, there are few clinical studies on the effect of orally administered A. vera gel on the skin. Aloe sterols are a type of plant sterols that have the capability to regulate the metabolism of glucose and lipids. In a recent study, we confirmed that ingested Aloe sterols reached the peripheral tissues through the bloodstream. However, their influence on dermal fibroblasts has not been investigated. Methods: First, we investigated the capability of Aloe sterols (cycloartenol and lophenol to stimulate human dermal fibroblasts in vitro. Then, we investigated the effect of intake of Aloe vera gel powder (AVGP containing 40 µg Aloe sterols on the skin conditions in Japanese women with dry skin in a randomized, double-blind, placebo-controlled trial. Results: After cocultivation with Aloe sterols, the production of collagen and hyaluronic acid increased by approximately two-fold and 1.5-fold, and gene expression levels of these enzymes responsible for their synthesis were also observed in human dermal fibroblasts. An increase in arm skin hydration was observed at 8 weeks in the AVGP group, whereas a slight decrease in arm skin hydration was noted in the placebo group. However, there was no statistical difference between AVGP and placebo groups in skin moisture. In subgroup analysis, the change in the mean wrinkle depth was significantly lower in the AVGP group than in the control group. In addition, percent body fat after 8 weeks was significantly lower in the AVGP group. No AVGP intake-dependent harmful phenomenon was observed during the intake

In this study, we compared the effects of the combination of Cil and amlodipine (Aml, which is an L-type CCB, with an angiotensin (Ang II receptor blocker on diabetic cardiorenal damage in spontaneously type 2 diabetic rats. Seventeen-week-old Otsuka Long-Evans Tokushima Fatty rats were randomly assigned to receive Cil, Aml, valsartan (Val, Cil + Val, Aml + Val, or a vehicle (eight rats per group for 22 weeks. Antihypertensive potencies were nearly equal among the CCB monotherapy groups and the combination therapy groups. The lowering of blood pressure by either treatment did not significantly affect the glycemic variables. However, exacerbations of renal and heart failure were significantly suppressed in rats administered Cil or Val, and additional suppression was observed in those administered Cil + Val. Although Val increased the renin–Ang system, Aml + Val treatment resulted in additional increases in these parameters, while Cil + Val did not show such effects. Furthermore, Cil increased the ratio of Ang-(1–7 to Ang-I, despite the fact that Val and Aml + Val decreased the Ang-(1–7 levels. These actions of Cil + Val might be due to their synergistic inhibitory effect on the activity of the SNS, and on aldosterone secretion through N-type calcium channel antagonism and Ang II

However, predictors of response to ECT have not been adequately studied using the Montgomery and Åsberg Depression Rating Scale, especially in older patients with treatment-resistant depression.Methods: This study included 18 Japanese patients who fulfilled the Diagnostic and Statistical Manual of Mental Disorders Fourth Edition Text Revision criteria for a diagnosis of major depressive disorder or bipolar disorder with a current major depressive episode, and met the definition of treatment-resistant depression outlined by Thase and Rush, scoring ≥21 on the Montgomery and Åsberg Depression Rating Scale. The three-factor model of the Montgomery and Åsberg Depression Rating Scale was used for analysis. Factor 1 was defined by three items, factor 2 by four items, and factor 3 by three items, representing dysphoria, retardation, and vegetative symptoms, respectively. ECT was performed twice a week for a total of six sessions using a Thymatron System IV device with the brief pulse technique. Clinical responses were defined on the basis of a ≥50% decrease in total pretreatment Montgomery and Åsberg Depression Rating Scale scores.Results: The mean pretreatment factor 2 score for responders (n = 7 was significantly lower than that for nonresponders (n = 11. Furthermore, a significant difference in mean factor 3 score between responders and nonresponders was observed one week after six sessions of ECT, indicating a time lag of response. No significant differences were observed for age, number of previous episodes, and duration of the current episode between responders and

The study aimed to verify whether the AGC approach was appropriate for the development of a safer DES, minimizing the risks of stent thrombosis due to delayed endothelialization by the drug and distal embolization due to cracking of the coating layer on the hinge parts of the DES on stent expansion. In the in vitro local drug diffusion study, we used rhodamine B as a model drug, and rhodamine B released from the AGC stent diffused predominantly into the abluminal side of the alginate artery model. Conversely, rhodamine B released from the CFC stent quickly spread to the luminal side of the artery model, where endothelial cell regeneration is required. In the biological responses study, the luminal surface of the iliac artery implanted with the AGC-sirolimus stent in a rabbit iliac artery for 2 weeks was completely covered with endothelial-like cells. On the other hand, the luminal surface of the iliac artery implanted with the CFC-sirolimus stent for 2 weeks only showed partial coverage with endothelial-like cells. While thrombosis was observed in two of the three CFC-sirolimus stents, it was observed in only one of the three AGC-sirolimus stents. Taken together, these findings indicate that the designed nonuniform coating (AGC is an appropriate approach to ensure a safer DES. However, the number of studies is limited and a larger study should be conducted to reach a statistically

This study aimed to investigate whether Aloe sterol intake affected skin conditions following sunlight exposure in Japanese men. Methods: We performed a 12-week, randomized, double-blind, placebo-controlled study to evaluate the effects of oral Aloe sterol supplementation on skin conditions in 48 apparently healthy men (age range: 30–59 years; average: 45 years. The subjects were instructed to expose the measurement position of the arms to the sunlight outdoors every day for 12 weeks. The skin parameters were measured at 0 (baseline, 4, 8, and 12 weeks. Results: Depending on the time for the revelation of the sunlight, the b* value and melanin index increased and the skin moisture decreased. After taking an Aloe sterol tablet daily for 12 weeks, the skin elasticity index (R2, R5, and R7 levels were significantly higher than the baseline value. There were no differences between the groups in these skin elasticity values. In the subgroup analysis of subjects aged <46 years, the change in the R5 and R7 was significantly higher in the Aloe group than in the placebo group at 8 weeks (P=0.0412 and P=0.0410, respectively.

    Purpose: To assess the relationship between large intracranial vessel occlusive vasculopathy (vasculopathy) and radiation therapy, and to clarify the clinical efficacy of magnetic resonance (MR) imaging in the diagnosis and screening of the vasculopathy. Methods and Materials: We retrospectively evaluated the medical records and serial MR images for 32 pediatric patients, in whom radiation therapy had been given to fields including the circle of Willis and major cerebral arteries. All children had periodically undergone follow-up neurologic assessment and MR imaging examinations at Kanagawa Children's Medical Center for more than one year after radiation therapy (range 1.3-14 years). Patients who had not remained free of tumor progression up to the time of final evaluation were excluded. Results: Vasculopathy developed in 6 of 32 patients 2-13 years after radiation therapy. Three of them presented with transient ischemic attacks (TIA) and the other three showed infarctions without preceding TIA. Steno-occlusive changes of major cerebral arteries were identified by MR imaging in all six patients, but not obtained in the remaining 26 patients. In the patients with TIA, MR imaging demonstrated steno-occlusive changes at the time of TIA, before irreversible infarction. They have been doing well subsequent to encephaloduraoarteriosyn-angiosis. In the three patients who presented infarction without preceding TIA, MR imaging did not demonstrate the vascular change before the onset of infarction, and two of them developed neurologic deficits. The mean exposure dose for the circle of Willis and major cerebral arteries in these six patients was significantly higher than that in the remaining 26 patients without this sequela (61Gy vs. 50Gy, p < 0.05). The mean age at radiation therapy of the six patients was lower, but the difference was not significant. Conclusion: The incidence of vasculopathy after radiation therapy has a considerable correlation with radiation dose and

    Purpose: To assess the effectiveness of high-dose rate intracavitary brachytherapy (HDR-ICR) in patients with grade 3 cervical intraepithelial neoplasia (CIN-3) and grade 3 vaginal intraepithelial neoplasia (VAIN-3). Methods and Materials: This was a retrospective analysis in 20 patients with CIN-3 (n = 14) or VAIN-3 (n = 6), average age 61.9 years, managed with HDR-ICR at Kanagawa Cancer Center. Two patients with CIN-3 with microinvasive foci and 11 other patients with CIN-3 were treated with HDR-ICR for cervical lesions. Six patients with CIN-3 after hysterectomy received HDR-ICR for recurrent or residual VAIN-3 lesions. One patient received radiation therapy for both CIN-3 and VAIN-3 lesions. All these patients but one were postmenopausal. Results: Seventeen patients were treated with HDR-ICR alone, and three with combined external radiation therapy. The dose was calculated at Point A located 2 cm superior to the external os and 2 cm lateral to the axis of the intrauterine tube for intact uterus. For lesions of the vaginal stump, the dose was calculated at a point 1 cm superior to the vaginal apex or 1 cm beyond vaginal mucosa. In the 14 patients treated for CIN-3 lesions, the mean total dose of HDR-ICR was 26.1 Gy (range 20-30). Six patients received HDR-ICR for VAIN-3 lesions with mean dose of 23.3 Gy (range 15-30). At follow-up (mean 90.5 months; range 13-153), 14 patients were alive and 6 had died owing to nonmalignant intercurrent disease. No patient developed recurrent disease. Rectal bleeding occurred in three patients, but this symptom subsided spontaneously. Moderate and severe vaginal reactions were noted in two patients, in whom the treatment had included the entire vagina. Conclusions: HDR-ICR can be employed as the primary management strategy for postmenopausal women with CIN-3. In intraepithelial neoplasia involving the vaginal wall after hysterectomy, HDR-ICR should be considered as an alternative to total vaginectomy

Urinary liver-type fatty acid binding protein (L-FABP increases along with tubular hypoxia and may be a detector of systemic circulation injury. The aim of this study was to evaluate the clinical usefulness of detecting increases in urinary L-FABP levels due to administration of CM, as a prognostic biomarker for cardiovascular disease in patients without occurrence of CM-induced nephropathy undergoing cardiac catheterization procedure (CCP. Methods: Retrospective longitudinal analyses of the relationship between urinary L-FABP levels and occurrence of cardiovascular events were performed (n=29. Urinary L-FABP was measured by ELISA before CCP, and at 6, 12, 24, and 48 hours after CCP. Results: Urinary L-FABP levels were significantly higher at 12 hours (P<0.05 and 24 hours (P<0.005 after CCP compared with before CCP, only in the patients with occurrence of cardiovascular events (n=17, but not in those without cardiovascular events (n=12. The parameter with the largest area under the curve (0.816 for predicting the occurrence of cardiovascular events was the change in urinary L-FABP at 24 hours after CCP. The difference in urinary L-FABP levels (ΔL-FABP ≥11.0 µg/g creatinine between before CCP and at 24 hours after CCP was a risk factor for the occurrence of cardiovascular events (hazard ratio, 4.93; 95% confidence interval, 1.27–19.13; P=0.021. Conclusion: Measurement of urinary L-FABP before CCP and at 24 hours after CCP in patients with mild to moderate renal dysfunction may be an important indicator for risk

    Prior research about the sexual and reproductive health of young women has relied mostly on self-reported survey studies. Thus, participant recruitment using Web-based methods can improve sexual and reproductive health research about cervical cancer prevention. In our prior study, we reported that Facebook is a promising way to reach young women for sexual and reproductive health research. However, it remains unknown whether Web-based or other conventional recruitment methods (ie, face-to-face or flyer distribution) yield comparable survey responses from similar participants. We conducted a survey to determine whether there was a difference in the sexual and reproductive health survey responses of young Japanese women based on recruitment methods: social media-based and conventional methods. From July 2012 to March 2013 (9 months), we invited women of ages 16-35 years in Kanagawa, Japan, to complete a Web-based questionnaire. They were recruited through either a social media-based (social networking site, SNS, group) or by conventional methods (conventional group). All participants enrolled were required to fill out and submit their responses through a Web-based questionnaire about their sexual and reproductive health for cervical cancer prevention. Of the 243 participants, 52.3% (127/243) were recruited by SNS, whereas 47.7% (116/243) were recruited by conventional methods. We found no differences between recruitment methods in responses to behaviors and attitudes to sexual and reproductive health survey, although more participants from the conventional group (15%, 14/95) chose not to answer the age of first intercourse compared with those from the SNS group (5.2%, 6/116; P=.03). No differences were found between recruitment methods in the responses of young Japanese women to a Web-based sexual and reproductive health survey. ©Yoko Motoki, Etsuko Miyagi, Masataka Taguri, Mikiko Asai-Sato, Takayuki Enomoto, John Dennis Wark, Suzanne Marie Garland.

Elevated urate levels are known to play a pivotal role in cardiovascular diseases, chronic renal disease, diabetes, and hypertension. Therefore, the development of potent uric acid transport inhibitors may lead to novel therapeutic agents to combat these human diseases. The current study investigates small molecular weight compounds and their ability to inhibit 14C-urate uptake in oocytes expressing hURAT1. Using the most promising drug candidates generated from our structure–activity relationship findings, we subsequently conducted in vitro hepatic metabolism and pharmacokinetic (PK studies in male Sprague-Dawley rats. Compounds were incubated with rat liver microsomes containing cofactors nicotinamide adenine dinucleotide phosphate and uridine 5'-diphosphoglucuronic acid. In vitro metabolism and PK samples were analyzed using liquid chromatography/mass spectrometry-mass spectrometry methods. Independently, six different inhibitors were orally (capsule dosing or intravenously (orbital sinus administered to fasting male Sprague-Dawley rats. Blood samples were collected and analyzed; these data were used to compare in vitro and in vivo metabolism and to

    InSAR is an application technique of synthetic aperture radars and is now drawing attention as a methodology capable of measuring subtle surface deformation over a wide area with a high spatial resolution. In this study, the authors applied the method of measuring long-term land subsidence by combining InSAR and time series analysis to Kanto Plains of Japan using 28 images of ENVISAT/ASAR data. In this measuring method, the value of land deformation is set as an unknown parameter and the optimal solution to the land deformation amount is derived by applying a smoothness-constrained inversion algorithm. The vicinity of the Kanto Plain started to subside in the 1910s, and became exposed to extreme land subsidence supposedly in accordance with the reconstruction efforts after the Second World War and the economic development activities. The main causes of the land subsidence include the intake of underground water for the use in industries, agriculture, waterworks, and other fields. In the Kujukuri area, the exploitation of soluble natural gas also counts. The Ministry of Environment reported in its documents created in fiscal 2006 that a total of 214 km2 in Tokyo and the six prefectures around the Plain had undergone a subsidence of 1 cm or more per a year. As a result of long-term land subsidence over approximately five and a half years from 13th January, 2003, to 30th June, 2008, unambiguous land deformation was detected in six areas: (i) Haneda Airport, (ii) Urayasu City, (iii) Kasukabe-Koshigaya, (iv) Southern Kanagawa, (v) Toride-Ryugasaki, and (vi) Kujukuri in Chiba Prefecture. In particular, the results for the Kujukuri area were compared with the leveling data taken around the same area to verify the measuring accuracy. The comparative study revealed that the regression formula between the results obtained by time series analysis and those by the leveling can be expressed as a straight line with a gradient of approximately 1, though including a bias of about

  19. Dynamic weakening of smectite-rich faults at intermediate to high velocities

    Smectite, one of the hydrous clay mineral, is ubiquitous in incoming sediments to subduction zones and is thought to weaken and stabilize subduction thrust faults. However, frictional properties of smectite alone cannot explain the nucleation and propagation of earthquake slip at the shallow plate boundary thrust which potentially causes the devastating tsunamis. Here, we investigate for the first time the effect of smectite fraction in smectite-quartz mixtures on friction at 30 μm/s to 1.3 m/s, to shed a light on the frictional response for the intermediate to high slip rates where the conventional friction experiments have not been explored. In the low slip rate of 30 μm/s, the steady-state coefficient of friction decreases non-linearly increasing smectite fraction: it drops rapidly at moderate fraction of 30-50 vol%. On the other hand, at the faster slip rates of ≥ 150 μm/s the friction lowers from 10-20 vol% fraction since drastic slip weakening appears for the mixtures of ~20 vol % smectite. Hence the fault suddenly loses the strength by adding only 20 % of smectite. The weakening seems to be associated with an excess pore pressure invoked by shear compaction and thermal pressurization during the experiments. This property weakens the fault strength and accelerates the fault slip, even if clay content is small (c.a. 15-35 %), leading to the large stress drop. In contrast, the faults rich in smectite (≥ 50 %) may cause small stress drop during the faulting owing to low friction coefficient of smectite at any slip rates. The results highlight that smectite content significantly affects frictional properties of faults and may generates the diversity in the subduction zone earthquakes.

    -EP in the United States, PETAL in France, and Vulcan PW in the United Kingdom, have allowed the study of novel approaches to producing and probing high-energy-density matter and exploring alternative ignition schemes. These scientific studies contribute to the physics understanding needed to develop inertial fusion energy as a commercial energy source and were also reported on at the Conference. Third-generation rep-rated and high-energy petawatt lasers are coming on line for strong field science studies and have opened up a new field of relativistic plasma physics. The extreme states achieved in these laser-plasma interactions are relevant to high-intensity x-ray applications, material processing, novel accelerators, and laboratory astrophysics. Recent activities and research in all these fields were discussed in 327 presentations, including three Keynote lectures, two Teller lectures, 21 plenary talks, 135 orals, and 166 posters. The proceedings collected in this volume underwent a rigorous peer-review process. The Editor is thankful to all the authors who agreed to act as referees on papers written by their fellow authors, and who worked both hard and diligently to complete this task in record time. We also thank the Technical Program Committee members who helped make this Ninth IFSA Conference possible. The American Nuclear Society Teller Award was bestowed during IFSA2015 on two key contributors to ICF science, Hiroshi Azechi and Jie Zhang. In addition, prizes were awarded to four students for their excellent presentations. On behalf of the various Committees, we extend our appreciation to everyone who helped make IFSA2015 a great success. (paper)

    La captura de átomos de boro, gadolinio o la mezcla de estos dos elementos para tratamiento del cáncer es un método experimental que está demostrando gran utilidad en el tratamiento de los tumores cerebrales malignos y de melanomas. Se espera que en un futuro próximo se pueda utilizar en la terapia del cáncer del pulmón, próstata y seno.

    La captura de átomos de boro con neutrones es un método bifásico: Requiere la inyección de una substancia con afinidad por el tejido neoplásico como el boro o el gadolinio y la exposición del enfermo a un haz de neutrones epitérmicos. Al entrar en contacto los neutrones con el boro o gadolinio captado por las células tumorales, se forma una reacción de fisión limitada a un radio de 5 a 10 micras la cual libera una gran cantidad de energía, produce la destrucción de las trenzas de DNA y del tejido tumoral. Las células normales que no captan boro o gadolinio permanecen indemnes.

    Antecedentes


    El método conocido por la sigla inglesa BNCT (Boron Neutron Capture Therapy fue iniciado en Bastan en los años cincuenta por el DI. William Sweet, profesor de neurocirugía de la Universidad de Harvard. Entre 1950 y 1960 se trataron cerca de 50 enfermos con tumores cerebrales malignos. Los resultados no fueron satisfactorios porque el compuesto borado y los neutrones que se utilizaron fueron de baja energía.

    En 1964 Hiroshi Hatanaka, un neurocirujano japonés, trabajó con el DI. Sweet y aprendió el método. A su regreso a Japón en 1967 modificó el sistema con la introducción de un compuesto borado de segunda generación conocido como BSH (borocaptato de sodio. Hatanaka utilizaba la técnica de craneotomía abierta bajo anestesia general y exposición a los neutrones térmicos.

    En 1993 Hatanaka presentó en el Congreso Mundial de Neurocirugía reunido en Acapu1co, México, los resultados de veinticinco años de trabajo y mostr

The objective of this study was to evaluate the factors associated with interpatient variability in the pharmacokinetics and pharmacodynamics of IHL-305 in patients with advanced solid tumors. IHL-305 was administered intravenously once every 4 weeks as part of a Phase I study. Pharmacokinetic studies of the liposomal sum total CPT-11, released CPT-11, SN-38, SN-38G, 7-ethyl-10-[4-N-(5-aminopentanoic acid-1-piperidino]-carbonyloxycamptothecin, and 7-ethyl-10-[4-amino-1-piperidino]-carbonyloxycamptothecin in plasma were performed. Noncompartmental and compartmental pharmacokinetic analyses were conducted using pharmacokinetic data for sum total CPT-11. The pharmacokinetic variability of IHL-305 is associated with linear and nonlinear clearance. Patients whose age and body composition (ratio of total body weight to ideal body weight [TBW/IBW] were greater than the median age and TBW/IBW of the study had a 1.7-fold to 2.6-fold higher ratio of released CPT-11 area under the concentration versus time

Word clouds described the characteristics of each disorder, such as "sleeping" and "anxiety" in depression and "pain" and "painful" in RA. Pharmacovigilance should maintain a strong focus on patients' actual experiences, concerns, and outcomes, and this approach can be expected to uncover hidden adverse event signals earlier and to help us understand adverse events in a patient-centered way. Patient-generated tōbyōki blogs in the TOBYO database showed unique characteristics that were different from the data in existing sources generated by health care professionals. Analysis of tōbyōki blogs would add value to the assessment of disorders with a high prevalence in women, psychiatric disorders in which subjective symptoms have important clinical meaning, refractory disorders, and other chronic disorders. ©Shinichi Matsuda, Kotonari Aoki, Shiho Tomizawa, Masayoshi Sone, Riwa Tanaka, Hiroshi Kuriki, Yoichiro Takahashi.

    2001-11-01

    A symposium with "Medical Treatment Support to Tuberculous Patients--From the standpoint of community support" as its theme was held at the 76th Annual Meeting of the Japanese Society for Tuberculosis (April 20, 2001). "Once, It is infected with tuberculosis, one have to complete medication with a sensitive antituberculosis drug by observing the prescribed dose and duration for successful treatment". For this to be promoted community, it is necessary that (1) to manage patient's medication by medical facilities, (2) to support patient's medication by health center and (3) to support patient's living by welfare offices. Not that each facilities takes such responsibilities alone, but various community must fulfill them continuously in liaison with one another. On what measures should be taken to that end, reports based on practical examples from Nagoya City, Yokohama City and Kanagawa Prefecture have been compiled as follows. 1. It was in-office liaison by conference that supported the DOTS activities of health nurses. 2. It is cooperating, without health, medical treatment, and welfare going out, as follows. (1) A system for hospitals and clinics to carry out DOTS treatment consistently has been kept in good condition. (2) For a patient to take a drug in front of a nurse has become common, causing the patients to be motivated. (3) Assignment of MSW and nurses in charge of DOTS sent from hospitals has make it possible to offer or exchange information smoothly among those concerned. (4) A system for many persons concerned to support patients timely has been kept in good condition. This resulted in an increase in the cure rate of tuberculosis in the areas which have day laborers' lodgings. 3. By DOTS for in-patients, the number of self-discharges has decreased by 1/3, and the treatment completion rate was 94%. 4. In promotion of DOTS for the patients who have health problems other than tuberculosis, the role MSW plays is great. 5. As conditions for supporting DOTS

    The Kanto region (Tokyo and the surrounding area) is one of the most densely populated urban areas in the world and has been devastated by repeated great earthquakes. This region is located at an island arc-island arc collision zone and a zone where Pacific and Philippine Sea plates are subducting. Great earthquakes along the Sagami trough, where the Philippine Sea slab is subducting, have repeatedly occurred. The 1703 Genroku and 1923 (Taisho) Kanto earthquakes caused severe damages in the metropolitan area. The recurrence periods of Taisho- and Genroku-type earthquakes are about 200-400 and 2000 years, respectively (e.g., Earthquake Research Committee, 2004). Many studies on the asperities along the Sagami trough have been carried out. Two asperities of the 1923 Kanto earthquake are located around the western part of Kanagawa prefecture (the base of the Izu peninsula) and around the Miura peninsula. An additional asperity of the 1703 Genroku earthquake is located the southern part of the Boso Peninsula. Slow slip events have also repeatedly occurred in an area adjacent to the asperities of the great earthquakes, off Boso peninsula (e.g., Ozawa et al 2007). In the cases of Nankai and Cascadia, slow slip events occur at deeper levels than the asperities, in a transition zone between the asperity and a region of steady slip. In contrast, slow slip events in the Kanto region have occurred at relatively shallow depths, at the same level as the asperity, raising the possibiltiy of friction controlled by different conditions (materials, fluid, or surface roughness) to those (temperature and pressure) encountered at Nankai and Cascadia. Deep seismic profiling have been carried out since the Special Project for Earthquake Disaster Mitigation in Urban areas (DaiDaiToku) (2002-2006). These profiling successfully presented a new image of the upper surface of the Philippine Sea slab (Sato et al. 2005), which is shallower than the previous models. This profiling also presents

    Great earthquakes along the Sagami trough, where the Philippine Sea slab is subducting, have repeatedly occurred. The 1703 Genroku and 1923 (Taisho) Kanto earthquakes (M 8.2 and M 7.9, respectively) are known as typical ones, and cause severe damages in the metropolitan area. The recurrence periods of Genroku- and Taisho-type earthquakes inferred from studies of wave cut terraces are about 200-400 and 2000 years, respectively (e.g., Earthquake Research Committee, 2004). We have inferred the source process of the 1923 Kanto earthquake from geodetic, teleseismic, and strong motion data (Kobayashi and Koketsu, 2005). Two asperities of the 1923 Kanto earthquake are located around the western part of Kanagawa prefecture (the base of the Izu peninsula) and around the Miura peninsula. After we adopted an updated fault plane model, which is based on a recent model of the Philippine Sea slab, the asperity around the Miura peninsula moves to the north (Sato et al., 2005). We have also investigated the slip distribution of the 1703 Genroku earthquake. We used crustal uplift and subsidence data investigated by Shishikura (2003), and inferred the slip distribution by using the same geometry of the fault as the 1923 Kanto earthquake. The peak of slip of 16 m is located the southern part of the Boso peninsula. Shape of the upper surface of the Philippine Sea slab is important to constrain extent of the asperities well. Sato et al. (2005) presented the shape in inland part, but less information in oceanic part except for the Tokyo bay. Kimura (2006) and Takeda et al. (2007) presented the shape in oceanic part. In this study, we compiled these slab models, and planed to reanalyze the slip distributions of the 1703 and 1923 earthquakes. We developed a new curved fault plane on the plate boundary between the Philippine Sea slab and inland plate. The curved fault plane was divided into 56 triangle subfaults. Point sources for the Green's function calculations are located at centroids

    In response to invading microorganisms, insect β-1,3-glucan recognition protein (βGRP), a soluble receptor in the hemolymph, binds to the surfaces of bacteria and fungi and activates serine protease cascades that promote destruction of pathogens by means of melanization or expression of antimicrobial peptides. Here we report on the nuclear magnetic resonance (NMR) solution structure of the N-terminal domain of βGRP (N-βGRP) from Indian meal moth (Plodia interpunctella), which is sufficient to activate the prophenoloxidase (proPO) pathway resulting in melanin formation. NMR and isothermal calorimetric titrations of N-βGRP with laminarihexaose, a glucose hexamer containing β-1,3 links, suggest a weak binding of the ligand. However, addition of laminarin, a glucose polysaccharide (~6 kDa) containing β-1,3 and β-1,6 links that activates the proPO pathway, to N-βGRP results in the loss of NMR cross-peaks from the backbone (15)N-(1)H groups of the protein, suggesting the formation of a large complex. Analytical ultracentrifugation (AUC) studies of formation of the N-βGRP-laminarin complex show that ligand binding induces self-association of the protein-carbohydrate complex into a macro structure, likely containing six protein and three laminarin molecules (~102 kDa). The macro complex is quite stable, as it does not undergo dissociation upon dilution to submicromolar concentrations. The structural model thus derived from this study for the N-βGRP-laminarin complex in solution differs from the one in which a single N-βGRP molecule has been proposed to bind to a triple-helical form of laminarin on the basis of an X-ray crystallographic structure of the N-βGRP-laminarihexaose complex [Kanagawa, M., Satoh, T., Ikeda, A., Adachi, Y., Ohno, N., and Yamaguchi, Y. (2011) J. Biol. Chem. 286, 29158-29165]. AUC studies and phenoloxidase activation measurements conducted with the designed mutants of N-βGRP indicate that electrostatic interactions involving Asp45, Arg54

So far, only obesity and quadriceps weakness are identified as modifiable risk factors for knee OA. Core muscle strengthening is becoming increasingly popular among older adults because of its ability to enhance the activities of daily living during old age. This study investigated the associations of the size and quality of the abdominal trunk muscles with radiographic knee osteoarthritis (RKOA. Methods: From 2012 to 2016, data were collected from 146 males and 135 females (age 63.9±13.4 years, BMI 23.2±3.8 kg/m2 at annual musculoskeletal examinations, including knee radiographs and body composition analyses, by dual-energy X-ray absorptiometry. Cross-sectional areas of abdominal trunk muscles were measured using a single-slice computed tomography scan image obtained at the level of the umbilicus. Results: The prevalence of RKOA was 21.2% in males and 28.1% in females. Compared to subjects without RKOA, subjects with RKOA were ~6 years older and had smaller paraspinal muscle (38.4±8.7 vs 33.1±10.1 cm2, p<0.01 in males; 24.1±7.1 vs 20.7±7.5 cm2, p<0.05 in females. In contrast, there was no decrease in appendicular or total lean mass, and only in females, BMI and total fat mass (FM were higher in subjects with RKOA (21.5±3.5 vs 24.5±4.4 kg/m2, 16.7±7.0 vs 20.5±7.7 kg, respectively, both p<0.01. After adjusting for age and sex, smaller cross-sectional area/lower attenuation value of the paraspinal muscles was associated with RKOA (both p<0.05, while greater

Steep declines in muscle mass following considerable weight reduction can decrease muscle strength and, consequently, physical performance. However, only a limited number of studies have examined the changes in muscle mass and strength in the context of interventional weight reduction programs. Thus, we investigated the influence of muscle mass decrease caused by diet-induced weight reduction on muscle strength in obese men.Methods: A total of 24 men with obesity (body mass index [BMI]: 29.2 ± 2.6 kg/m2; age: 52.4 ± 10.0 years attended a 12-week weight reduction program that implemented dietary restrictions. Each participant underwent assessments of body weight (by a digital scale, body composition (by whole-body dual-energy X-ray absorptiometry [DEXA], and upper and lower extremity muscle strength (by a hand-held dynamometer and a Biodex System 3 dynamometer, respectively before and after the program.Results: The program led to significant reductions of 10.5% of weight and 6.1% of lower extremity muscle mass. Similarly, lower extremity muscle strength (measured using a Biodex System 3 dynamometer was significantly decreased (isometric 60° peak torque decreased by 10% and

  20. Titan Casts Revealing Shadow

    A rare celestial event was captured by NASA's Chandra X-ray Observatory as Titan -- Saturn's largest moon and the only moon in the Solar System with a thick atmosphere -- crossed in front of the X-ray bright Crab Nebula. The X-ray shadow cast by Titan allowed astronomers to make the first X-ray measurement of the extent of its atmosphere. On January 5, 2003, Titan transited the Crab Nebula, the remnant of a supernova explosion that was observed to occur in the year 1054. Although Saturn and Titan pass within a few degrees of the Crab Nebula every 30 years, they rarely pass directly in front of it. "This may have been the first transit of the Crab Nebula by Titan since the birth of the Crab Nebula," said Koji Mori of Pennsylvania State University in University Park, and lead author on an Astrophysical Journal paper describing these results. "The next similar conjunction will take place in the year 2267, so this was truly a once in a lifetime event." Animation of Titan's Shadow on Crab Nebula Animation of Titan's Shadow on Crab Nebula Chandra's observation revealed that the diameter of the X-ray shadow cast by Titan was larger than the diameter of its solid surface. The difference in diameters gives a measurement of about 550 miles (880 kilometers) for the height of the X-ray absorbing region of Titan's atmosphere. The extent of the upper atmosphere is consistent with, or slightly (10-15%) larger, than that implied by Voyager I observations made at radio, infrared, and ultraviolet wavelengths in 1980. "Saturn was about 5% closer to the Sun in 2003, so increased solar heating of Titan may account for some of this atmospheric expansion," said Hiroshi Tsunemi of Osaka University in Japan, one of the coauthors on the paper. The X-ray brightness and extent of the Crab Nebula made it possible to study the tiny X-ray shadow cast by Titan during its transit. By using Chandra to precisely track Titan's position, astronomers were able to measure a shadow one arcsecond in

    the solar wind. The solar wind itself is launched from the Sun and carries the Sun’s magnetic field throughout the Solar System. Sometimes this magnetic field is aligned with Earth’s and sometimes it points in the opposite direction. When the two fields point in opposite directions, scientists understand how ‘doors’ in Earth’s field can open. This phenomenon, called ‘magnetic reconnection’, allows the solar wind to flow in and collect in the reservoir known as the boundary layer. On the contrary, when the fields are aligned they should present an impenetrable barrier to the flow. However, spacecraft measurements of the boundary layer, dating back to 1987, present a puzzle because they clearly show that the boundary layer is fuller when the fields are aligned than when they are not. So how is the solar wind getting in? Thanks to the data from the four formation-flying spacecraft of ESA’s Cluster mission, scientists have made a breakthrough. On 20 November 2001, the Cluster flotilla was heading around from behind Earth and had just arrived at the dusk side of the planet, where the solar wind slides past Earth’s magnetosphere. There it began to encounter gigantic vortices of gas at the magnetopause, the outer ‘edge’ of the magnetosphere. “These vortices were really huge structures, about six Earth radii across,” says Hiroshi Hasegawa, Dartmouth College, New Hampshire who has been analysing the data with help from an international team of colleagues. Their results place the size of the vortices at almost 40 000 kilometres each, and this is the first time such structures have been detected. These vortices are known as products of Kelvin-Helmholtz instabilities (KHI). They can occur when two adjacent flows are travelling with different speeds, so one is slipping past the other. Good examples of such instabilities are the waves whipped up by the wind slipping across the surface of the ocean. Although KHI-waves had been observed before, this is the

    award was Steven A. Sabbagh et al for the paper entitled 'Resistive wall stabilized operation in rotating high beta NSTX plasmas' (Nucl. Fusion 46 635-644). Reviews Last year I announced a revival of Nuclear Fusion Reviews, following a decision by the Board of Editors. 'A review of zonal flow experiments', by Akihide Fujisawa was the first fruit of this. In 2010, we are expecting to publish further review articles, the first of which is entitled 'Gyrokinetic simulations of turbulent transport' by Xavier Garbet, Yasuhiro Idomura, Laurent Villard and Tomo-Hiko Watanabe. Letters At the 2009 Board of Editors Meeting in Atlanta, the current letters procedure was summarized and it was noted that the peer review time for Letters is quite variable. Some are accepted within a month of submission, others take longer. Since the purpose of Letters is to provide a route for rapid communication, this is quite an important matter. It was agreed that the Board of Editors would play a more active role in the Letter approval process. If a reviewer asks for a second revision the Editor or a Board of Editors member will be queried as to whether the submission should still be treated as a Letter rather than a regular Paper. The Board of Editors The following Board of Editors members reached the end of their term in 2009: Amanda Hubbard, Yaroslav Kolesnichenko, Kunioki Mima, Boris Sharkov and Michael Ulrickson. On behalf of the Nuclear Fusion Office and the Chairman of the Board of Editors, Mitsuru Kikuchi, I would like to thank them for their efforts in support of the journal. At the same time, we welcomed: Hiroshi Azechi, Xuru Duan, Richard Hawryluk, Sergey Konovalov, Bruce Lipschultz, Peter Norreys, Francesco Romanelli, Tony Taylor and Hartmut Zohm. I am sure that such an illustrious group does not need any introduction to the readers of Nuclear Fusion and I am confident that the new members can only further the success of the journal. It is with great sadness that I have to note the

    cater the need to prevent the spreading of contagious viruses during epidemics which may occur in the future. However it is essential to study the specific targets of Clinister in viruses at a molecular level, and the same is under progress. Invention – II : A unique polymer invented by a chemical engineer A chemical engineer Prof. Yuichi Mori jointly with polymer scientist Dr Hiroshi Yoshioka developed a thermoreversible polymer (TGP hydrogel composed of thermoresponsive polymer block [poly (Nisopropylacrylamide- co-n-butyl methacrylate (poly NIPAAm-co-BMA] and the hydrophilic polymer block [polyethylene glycol (PEG] (commercial name :Mebiol gel [5]. This Mebiol gel provides a suitable in vitro environment enabling culture expansion of cells in the lab without the use of biological components such as amniotic membrane or feeder layers. TGP has been earlier employed for the three-dimensional culture of many cell types like corneal limbal stem cells [6], chondrocytes [7], embryonic stem cells [8], hepatocytes [9], induced pluripotent stem (iPS cells [8] and bone marrow mononuclear cells [10]. TGP has been used for transportation of corneal endothelial precursor cells over long distances without cool preservation [11], for micro-encapsulation of islet cells [12] and as a wound dressing [13]. TGP has been intralesionally applied along with stem cells in an animal model of spinal cord in injury [10]. TGP is a unique polymer capable of maintaining stem cells in an undifferentiated manner for a longer period of time [14]. It does not affect the gene expression profile [15] and the karyotype of the cells is maintained even after long term culture [16]. The safety and efficacy of TGP as a valuable scaffold material has been established in the various in vitro and translational studies [5]. Inter-Disciplinary-Interaction based on the Invention-II: Mebiol Gel as a 3D scaffold for hepatocytes and viral replication Mebiol Gel was used as a 3D scaffold for growing hepatocyte cell
