    Full Text Available This article responds to Satoshi Kanazawa's thoughtful and entertaining comments about my article concerning the Asian future of evolutionary psychology. Contra Kanazawa's argument that Asian cultural traditions and/or character inhibit Asian scientific creativity, I review historical evidence of high Asian creativity, and psychometric evidence of high Asian intelligence (a cognitive trait and openness to experience (a personality trait — two key components of creativity. Contra Kanazawa's concern that political correctness is a bigger threat to American evolutionary psychology than religious fundamentalism, I review evidence from research funding patterns and student attitudes suggesting that fundamentalism is more harmful and pervasive. Finally, in response to Kanazawa's focus on tall buildings as indexes of national wealth and creativity, I find that 13 of the world's tallest 25 buildings are in China, Hong Kong, or Taiwan — of which 11 were built in the last decade. Asian creativity, secularism, and architectural prominence point to a bright future for Asian science.

    2002-02-01

    For the purpose of promoting the introduction of new energy and enhancing the awareness of it in Kanazawa City, Ishikawa Prefecture, an investigational study was conducted of the energy demand amount of the city, existence amount of new energy and project for new energy introduction, and a vision was worked out. The energy demand amount of the city was approximately 42 million GJ. The amount of CO2 emitted from this was estimated at approximately 880,000 t-C. The rate of energy source was 65.3% of petroleum-base energy, 24.7% of electric power and 10.0% of gas. As viewed by sector, the energy demand amount consisted of 38.1% in the commercial/residential sector, 32.2% in the transportation sector and 29.7% in the industrial sector. As the project for new energy introduction, the following were studied: introduction of wind power generation to the sport recreation zone of the mountain area; introduction of natural gas cogeneration to the city hospital; introduction of hydroelectric power generation using the idle head of filtration plant; utilization of the sewage heat and sewage digestion gas at the water quality control center, introduction of clean energy vehicle to official vehicle; introduction of photovoltaic power generation to park light/school, etc. (NEDO)

    In August 2007, an outbreak of equine influenza occurred among vaccinated racehorses with Japanese commercial equine influenza vaccine at Kanazawa Racecourse in Ishikawa prefecture in Japan. Apparent symptoms were pyrexia (38.2-41.0 degrees C) and nasal discharge with or without coughing, although approximately half of the infected horses were subclinical. All horses had been shot with a vaccine that contained two inactivated H3N8 influenza virus strains [A/equine/La Plata/93 (La Plata/93) of American lineage and A/equine/Avesta/93 (Avesta/93) of European lineage] and an H7N7 strain (A/equine/Newmarket/1/77). Influenza virus, A/equine/Kanazawa/1/2007 (H3N8) (Kanazawa/07), was isolated from one of the nasal swab samples of diseased horses. Phylogenetic analysis indicated that Kanazawa/07 was classified into the American sublineage Florida. In addition, four amino acid substitutions were found in the antigenic sites B and E in the HA1 subunit protein of Kanazawa/07 in comparison with that of La Plata/93. Hemagglutination-inhibition (HI) test using 16 serum samples from recovering horses revealed that 1.4- to 8-fold difference in titers between Kanazawa/07 and either of the vaccine strains. The present findings suggest that Japanese commercial inactivated vaccine contributed to reducing the morbidity rate and manifestation of the clinical signs of horses infected with Kanazawa/07 that may be antigenically different from the vaccine strains.

    The Nuclear power plant accident at Fukushima caused by the earthquake and tsunami disaster in March, 2011 led the public to fear the considerable-range contamination with radioactivity. For the reason, we started environmental monitoring on radioactivity just outside of the RI facility in the Kakuma campus of Kanazawa Univ. A high-volume dust sampler (SHIBATA, HV-1000) was used to collect air dust onto a filter and rain water was collected in a plastic container placed on the rooftop of the facility as well. The samples were assayed by gamma-ray spectrometer with germanium detectors to obtain the concentrations of I-131, Cs-134, and Cs-137. The data were compared with those measured in the other areas in Japan to discuss how the activities diffused and migrated from the plant to many places in Japan. The peaking dates of the activities coincided with those by a trajectory calculation of air from Fukushima. The trend was confirmed for the other data in other areas. (author)

    Full Text Available Drilling an ultra-deep hole in an intact portion of oceanic lithosphere, through the crust to the Mohorovičić discontinuity (the ‘Moho’, and into the uppermost mantle is a long-standing ambition of scientific ocean drilling (Bascom, 1961; Shor, 1985; Ildefonse et al., 2007. It remains essential to answer fundamental questions about the dynamics of the Earth and global elemental cycles. The global system of mid-ocean ridges and the new oceanic lithosphere formed at these spreading centers are the principal pathways for energy and mass exchange between the Earth’s interior, hydrosphere, and biosphere. Bio-geochemical reactions between the oceans and oceanic crust continue from ridge to subduction zone, and the physical and chemical changes to the ocean lithosphere provide inventories of these thermal, chemical, and biological exchanges.The 2010 MoHole workshop in Kanazawa, Japan followed from several recent scientific planning meetings on ocean lithosphere drilling, in particular the Mission Moho Workshop in 2006 (Christie et al., 2006; Ildefonse et al., 2007 and the “Melting, Magma, Fluids and Life” meeting in 2009 (Teagle et al., 2009. Those previous meetings reacheda consensus that a deep hole through a complete section of fast-spread ocean crust is a renewed priority for the ocean lithosphere community. The scientific rationale for drilling a MoHole in fast-spread crust was developed in the workshop reports (available online and most thoroughly articulated in the 2007 IODP Mission Moho drilling proposal (IODP Prop 719MP; www.missionmoho.org.

    We have been studying Anisakidae larvae, their intermediate hosts and their final hosts in the northern Japan Sea area. These larvae cause anisakidosis. According to the investigation, the recent burst of pseudoterranovosis in this area can be attributed to the increased presence of sea lions, which proliferate in the Arctic region, then migrate to the northern Japan Sea and eat the intermediate host fish. In a stomach of a male sea lion that was captured in February 1995, we found more than 4,500 Pseudoterranova decipiens. Although there is no known circumstance in which a human would consume an adult worm of Anisakis nematode, an astonishing case of this was found in Kanazawa; a female young adult Pseudoterranova decipiens undergoing the final metamorphosis was emitted from a patient. This indicates that the Anisakis larva can mature into the adult worm in humans. It is postulated that the Pseudoterranova decipiens larva is in the process of adapting to use humans as the final host.

    Full Text Available Ever since the first introduction of Shakespeare to a Japanese audience in the nineteenth century, his plays have functioned as “contact zones,” which are translingual interfaces between communities and their cultures; points of negotiation, misunderstanding and mutual transformation. In the context of what is ostensibly a monolingual society, Japanese Shakespeare has produced a limited number of performances that have attempted to be multilingual. Most of them, however, turn out to be translingual, blurring the borders of linguistic specificity.

We report the safety and performance of HDD.Methods: In this retrospective, non-randomized clinical trial, 46 patients (14 males and 32 females; age range 39–91 years; mean age ± SD 70.3±12.0 years who had lacrimal disorders were examined with HDD and conventional dacryoendoscopy (CD. The high-definition dacryoendoscope had 15,000 picture element image fibers and an advanced objective lens. Its outer diameter was 0.9–1.2 mm. Air insufflation was controlled at 0–20 kPa with a digital manometer-based pressure-controlled air-insufflation system to evaluate the quality of the image. The HDD had an air/saline irrigation channel between the outer sheath (outer diameter =1.2 mm and the metal inner sheath of the endoscope. We used it and the CD in air, saline, and diluted milk saline with and without manual irrigation to quantitatively evaluate the effect of air pressure and saline irrigation on image quality.Results: In vivo, the most significant improvement in image quality was demonstrated with air-insufflated (5–15 kPa HDD, as compared with saline-irrigated HDD and saline-irrigated CD. No emphysema or damage was noted under observation with HDD. In vitro, no significant difference was demonstrated between air-insufflated HDD and saline-irrigated HDD. In vitro, the image quality of air-insufflated HDD was significantly improved as compared with that of saline-irrigated CD.Conclusion: Pressure-controlled (5–15 kPa air

  14. Molecular diagnosis of the arowanas Osteoglossum ferreirai Kanazawa, 1966 and O. bicirrhossum (Cuvier, 1829 from the Orinoco and Amazon River basins

    Directory of Open Access Journals (Sweden)

    Maria Doris Escobar L.

    Full Text Available The arowanas, fishes of Gondwanan origin, are represented in South America by the genus Osteoglossum. All species were initially reported as being exclusive to the Amazon region, with O. ferreirai restricted to the Negro River basin and O. bicirrhosum to the Amazon and Essequibo Rivers basin. Starting in the mid 1970's it was reported that O. ferreirai also occurs in the Orinoco River basin. In all regions the arowanas assumed significant socio-economic importance due to their popularity in the international ornamental fish trade, leading to over-exploitation of both species in some areas. The Orinoco populations are particularly heavily exploited, and thus conservation and management measures are needed. Both depend on the clarification of taxonomic status, and phylogenetic distinctness of the Orinoco populations. With the goal of molecularly characterizing the two species of Osteoglossum, and comparing populations of Osteoglossum from the Orinoco and Amazon basins, we characterized individuals sampled from eight localities, one in the Orinoco River basin and seven in the Amazon River basin. We sampled 39 individuals, obtaining 1004 base pairs, of which 79 were synapomorphies. Genetic distance between the two species calculated using the HKY + G model of molecular evolution was 8.94%. Intraspecific distances ranged from 0.42% in O. bicirrhosum to 0.10% in O. ferreirai. The genetic characterization confirmed the taxonomic status of O. ferreirai in the Orinoco basin, and suggested that its distribution in the Orinoco basin is unlikely to be the result of vicariance or natural dispersal, but rather an anthropic introduction.

    Synchrony detection between burst and non-burst spikes is known to be one functional example of depressing synapses. Kanazawa et al. demonstrated synchrony detection with MOS depressing synapse circuits. They found that the performance of a network with depressing synapses that discriminates between burst and random input spikes increases non-monotonically as the static device mismatch is increased. We designed a single-electron depressing synapse and constructed the same network as in Kanazawa's study to develop noise-tolerant single-electron circuits. We examined the temperature characteristics and explored possible architecture that enables single-electron circuits to operate at T > 0 K

However, weekly paclitaxel (wPTX has become the preferable second-line chemotherapy in Japan. Histone deacetylase (HDAC inhibitors have been shown to have antiproliferative activity through cell-cycle arrest, differentiation, and apoptosis in gastric cancer cells. One HDAC inhibitor, valproic acid (VPA, also inhibits tumor growth by inducing apoptosis, and enhances the efficacy of paclitaxel in a mouse xenograft model of gastric cancer. wPTX plus VPA as a second-line chemotherapy is expected to improve survival in gastric cancer patients. A multicenter randomized Phase II study was conducted to compare the effects of wPTX plus VPA and wPTX alone. A total of 66 patients participated in this study. The primary end point of the study was overall survival, and secondary end points were progression-free survival, response rate, and assessment of peripheral neuropathy.

    This study estimates atmospheric concentrations of chlorinated polycyclic aromatic hydrocarbons (ClPAHs) and polycyclic aromatic hydrocarbons (PAHs) in East Asia using a Gas Chromatograph with High Resolution Mass Spectrometer (GC-HRMS). ClPAHs are ubiquitously generated from PAHs through substitution, and some ClPAHs show higher aryl hydrocarbon receptor (AhR)-mediated activities than their parent PAHs. Atmospheric particles were collected using a high-volume air sampler equipped with a quartz-fiber filter. We determined the ClPAH concentrations of atmospheric particles collected in Japan (Sapporo, Sagamihara, Kanazawa, and Kitakyushu), Korea (Busan), and China (Beijing). The concentrations of ClPAHs were highest in the winter Beijing sample, where the total mean concentration was approximately 15-70 times higher than in the winter samples from Japan and Korea. The concentrations of Σ19ClPAHs and Σ9PAHs were significantly correlated in the Kanazawa and the Busan samples. This indicates that within those cities ClPAHs and PAHs share the same origin, implying direct chlorination of parent PAHs. Toxic equivalent concentrations (TEQs) of the total ClPAHs and PAHs were lowest in Kanazawa in the summer, reaching 1.18 and 2610fg-TEQm(-3) respectively, and highest in Beijing in the winter, reaching 627 and 4240000fg-TEQm(-3) respectively.

  7. Literacy not intelligence moderates the relationships between economic development, income inequality and health.

    Kanazawa (2006) presented data allegedly supporting a racist version of evolutionary psychology that claims that the populations of wealthier and more egalitarian societies live longer and stay healthier, not because they are wealthier and more egalitarian, but because they are more intelligent. The objectives of this study are: (i) to determine the relationship between IQ and literacy in Kanazawa's sample of countries and (ii) to reanalyse Kanazawa's dataset using measures of literacy in lieu of national IQ test scores. Correlation and regression were employed. National literacy scores across the countries in the sample are highly skewed. In spite of this, the literacy measures are highly correlated with alleged differences in national IQ (r = .83-.86). The measure of literacy together with economic development (GDPpc) and income inequality (Gini coefficient) control at least 59-64% of the variance in national life expectancy at birth. There is no scientific justification for believing that alleged intelligence differences play any role in explaining international differences in health status. Measures of alleged national IQ scores are highly confounded with differences in literacy. Literacy is a key factor in the health of any community and policies designed to enhance the literacy of a population are expected to lead to significant improvements in health status.

    Experimental studies are carried out on compression of the density distribution of a pure electron plasma confined in a Malmberg-Penning Trap in Kanazawa University. More than six times increase of the on-axis density is observed under application of an external rotating electric field that couples to low-order Trivelpiece-Gould modes. Axial compression of the density distribution with the axial length of a factor of two is achieved by controlling the confining potential at both ends of the plasma. Substantial increase of the axial kinetic energy is observed during the axial compression. (author)

  11. Natural Vibration Analysis of Clamped Rectangular Orthotropic Plates

    Science.gov (United States)

    dalaei, m.; kerr, a. d.

    The natural vibrations of clamped rectangular orthotropic plates are analyzed using the extended Kantorovich method. The developed iterative scheme converges very rapidly to the final result. The obtained natural frequencies are evaluated for a square plate made of Kevlar 49 Epoxy and the obtained results are compared with those published by Kanazawa and Kawai, and by Leissa. The agreement was found to be very close. As there are no exact analytical solutions for clamped rectangular plates, the generated closed form expression for the natural modes, and the corresponding natural frequencies, are very suitable for use in engineering analyses.

    The authors studied and developed an electrostatic 222 Rn monitor and have measured continuously outdoor radon ( 222 Rn) concentrations at Nagoya University since 1985. Four 222 Rn monitors were newly constructed to measure outdoor 222 Rn concentrations at other locations. The 222 Rn concentrations at Nagoya and Kasugai show a clear diurnal variation in autumn, and a seasonal pattern of a spring-summer minimum and a autumn-winter maximum. The results at Toki are the same pattern as that at Nagoya except spring. The concentrations at Kanazawa show a slight seasonal variation. A clear diurnal variation is observed in summer. (4 figs.)

    Modeling carried out demonstrates possibility of generation of gigawatt power level S band microwave pulse with duration of several nanoseconds using superradiation of short electron beam moving along slow-wave periodical structure. A 10 ns / 500 keV / 5 kA accelerator of Kanazawa University can be used in such experiments. It is shown that significant increasing peak power can be obtained by optimization of voltage and current pulses waveforms. Required increasing of electron energy and current by the end of electron pulse can be achieved by using self-acceleration of a short beam passing through a system of passive cavities. (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.

Phylogenetic analysis of hemagglutinin (HA) and neuraminidase (NA) genes showed that three isolates from horses in Japan and imported from Canada belonged to the same branch, clade 1 of the Florida sublineage, while the isolates from horses in Mongolia and imported from Belgium belonged to another branch, clade 2 of the Florida sublineage. Reactivity patterns of a panel of monoclonal antibodies to the HA of A/equine/Kanazawa/1/2007 (H3N8) with the five isolates indicate that the HAs of these viruses were antigenically similar to each other and to the reference strains A/equine/La Plata/1/1993 (H3N8) and A/equine/Avesta/1/1993 (H3N8). The present findings indicate that extensive antigenic variation has not accumulated among H3N8 influenza viruses in horses.

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.

    The concentrations of organically-bound 14 C in tree-ring cellulose of a Japanese Black Pine grown in Shika-machi (37.0 deg. N, 136.8 deg. E) and those of a Japanese Cedar grown in Kanazawa (36.5 deg. N, 136.7 deg. E), Japan, were analyzed for the ring-years from 1989 to 1998 by the accelerator mass spectrometric measurement. The results were compared with those of the same samples analyzed by the liquid scintillation counting measurement to determine the reliability of liquid scintillation counting measurement. An important result of this study is that the sensitivity and reproducibility of accelerator mass spectrometric measurement was almost equal to that of liquid scintillation counting measurement.

    During video-assisted thoracic surgery (VATS), localization is sometimes needed to detect a target lesion that is too small and/or too far from the pleura. In 1995, Kanazawa et al. developed short hookwire and suture system. Since then, this system has been placed often for selected targets before VATS in Japan. This short hookwire and suture system is a representative preoperative localization method and the placement procedure is well-established. Its placement success rates are very high (range: 97.6%-99.6%), and dislodgement of this short hookwire rarely occurs with an incidence of 0.4%-2.5%. The most common complication of short hookwire placement is pneumothorax (incidence: 32.1%-68.1%), followed by pulmonary hemorrhage (incidence: 8.9%-41.6%). Complications are frequent; however, most complications are minor and asymptomatic. Copyright © 2018 Société française de radiologie. Published by Elsevier Masson SAS. All rights reserved.

    Pulmonary artery aneurysms are rare lesions. Clagett et al reported that one aneurysm of the pulmonary artery may be found in approximately 14,000 necropsies. We have experienced a case of giant pulmonary artery aneurysm confirmed by computed tomography. A 38 year-old man with atrial septal defect admitted to Kanazawa City Hospital. He had been pointed out of a right hilar mass when he was 26 years old. His complaint was bloody sputum and cough. Pulmonary angiography was not useful for the definite diagnosis because of its mural thrombi. Enhanced computed tomography showed a giant pulmonary artery aneurysm with a mural thrombi in its cavity. This shows that enhanced computed tomography is very useful for the diagnosis of a pulmonary artery aneurysm with a mural thrombi in its cavity. (author)

    The demand of 3D city modeling has been increasing in many applications such as urban planing, computer gaming with realistic city environment, car navigation system with showing 3D city map, virtual city tourism inviting future visitors to a virtual city walkthrough and others. We proposed a simple method for reconstructing a 3D urban landscape from airborne LiDAR point cloud data. The automatic reconstruction method of a 3D urban landscape was implemented by the integration of all connected regions, which were extracted and extruded from the altitude mask images. These mask images were generated from the gray scale LiDAR image by the altitude threshold ranges. In this study we demonstrated successfully in the case of Kanazawa city center scene by applying the proposed method to the airborne LiDAR point cloud data.

    For promoting efficient use of energy, a new concept is required that society can choose to make a positive approach toward a solar energy based rural community which maximizes harmony with nature. This basic concept uses a water lake as a thermal energy storage. Thermocline measurements were made at the Uchikawa Dam Lake located in Kanazawa, Ishikawa, Japan to evaluate several kind of exergy contents as a new energy supply potential. The data indicated that the system could be developed with full potential as a seasonal energy storage to be used for mostly regional cooling. This concept seems interesting to invite internationally an energy efficient society to be employed in LDCs as well as in developed countries. (author) 12 figs., 2 tabs., 7 refs.

  14. Health, wealth and IQ in sub-Saharan Africa: challenges facing the 'Savanna Principle' as an explanation for global inequalities in health.

    Ellison, George T H

    2007-05-01

    Kanazawa's (2006) national- and individual-level analyses seem to support his hypothesis that: IQ scores are better predictors of health than wealth or inequality, except in 'evolutionarily familiar' sub-Saharan Africa which offers limited selection for intelligence (British Journal of Health Psychology 11: 623-42). However, the present paper exposes the flawed assumptions, questionable data, inappropriate analyses and biased interpretations on which this thesis was based. It questions the assumptions that: IQ scores are markers of adaptive genetic differences in intelligence; humans evolved within a predictable 'environment of evolutionary adaptedness': and this environment characterizes contemporary sub-Saharan Africa, offering little selection for intelligence. It also demonstrates that the macro-level data on which these analyses were based were collected across a range of different years, using a range of different sources, and were significantly intercorrelated. While none of these analyses adjusted for study year or study type, all were susceptible to multicollinearity and the 'ecological fallacy'. These flaws were compounded by the selective presentation and partial interpretation of the analyses, which focused on the absence of an 'independent' relationship between 'national IQ' and health within sub-Saharan Africa, but ignored the fact that this is also true for every other region of the world. Likewise, the individual-level analyses did not explore the relationship between IQ scores, self-reported income and health by race, which would have demonstrated the impact of the ecological fallacy. Instead, Kanazawa (2006) mistook statistical associations for evidence of causality and falsely concluded that populations in sub-Saharan Africa are less healthy because they are unintelligent and not because they are poor.

Demographic data such as cause of corneal perforation, surgical procedures, and visual outcomes were retrospectively analyzed.Results: The causes of corneal perforation (n=31 were divided into infectious (n=8, 26% and noninfectious (n=23, 74% categories. Infectious causes included fungal ulcer, herpetic stromal necrotizing keratitis, and bacterial ulcer. The causes of noninfectious keratopathy included corneal melting after removal of a metal foreign body, severe dry eye, lagophthalmos, canaliculitis, the oral anticancer drug S-1, keratoconus, rheumatoid arthritis, neurotrophic ulcer, atopic keratoconjunctivitis, and unknown causes. Initial surgical procedures included central large corneal graft (n=17, small corneal graft (n=7, and amniotic membrane transplantation (n=7. In two cases the perforation could not be sealed during the first surgical treatment and required subsequent procedures. All infectious keratitis required central large penetrating keratoplasty to obtain anatomical cure. In contrast, several surgical options were used for the treatment of noninfectious keratitis. After surgical treatment, anatomical cure was obtained in all cases. Mean postoperative best corrected visual acuity was better at 6 months (logMAR 1.3 than preoperatively (logMAR 1.8.Conclusion: Surgical therapies for corneal perforations in our hospital included central large lamellar/penetrating keratoplasty, small peripheral patch graft, and amniotic membrane transplantation.

Patients and methods: Two patients (67-year-old male and his 26-year-old son with OI type I were included in this study. Slit lamp biomicroscopic and in vivo laser confocal microscopic examinations were performed for both patients. Central corneal thickness and central endothelial cell density were also measured. Results: Although the corneas looked clear with normal endothelial density for both eyes in both patients, they were quite thin (386 µm oculus dexter (OD (the right eye and 384 µm oculus sinister (OS (the left eye in the father and 430 µm OD and 425 µm OS in the son. In both patients, slit lamp biomicroscopic and in vivo laser confocal microscopic examination showed similar results. Anterior corneal mosaics produced by rubbing the eyelid under fluorescein were completely absent in both eyes. In vivo laser confocal microscopy revealed an absent or atrophic Bowman's layer; a trace of a presumed Bowman's layer and/or basement membrane was barely visible with high intensity. Additionally, K-structures were completely absent in both eyes. Conclusion: The absence of K-structures and fluorescein anterior corneal mosaics strongly suggested an abnormality of Bowman's layer in these OI patients.

    Total suspended particulate matter (TSP) was collected during the summer and winter in five Japanese cities spanning Hokkaido to Kyushu (Sapporo, Kanazawa, Tokyo, Sagamihara and Kitakyushu) from 1997 to 2014. Nine polycyclic aromatic hydrocarbons (PAHs) with four to six rings, including pyrene (Pyr) and benzo[a]pyrene (BaP), were identified using high-performance liquid chromatography (HPLC) with fluorescence detection. Two nitropolycyclic aromatic hydrocarbons (NPAHs), 1-nitropyrene (1-NP) and 6-nitrobenzo[a]pyrene (6-NBaP), were identified by HPLC with chemiluminescence detection. A comparison of PAH and NPAH concentrations and [NPAH]/[PAH] ratios such as [1-NP]/[Pyr] and [6-NBaP]/[BaP] revealed the following characteristics in the five cities: (1) In Sapporo, Kanazawa, Tokyo and Sagamihara, the concentrations of PAHs and NPAHs were high at the beginning of the sampling period and then steadily decreased, with NPAHs decreasing faster than PAHs. The large initial [1-NP]/[Pyr] ratios suggest that the major contributor was automobiles but subsequent decreases in this ratio suggest decreased automobile contributions. (2) By contrast, PAH concentrations in Kitakyushu did not decrease during the sampling period, though concentrations of NPAHs decreased. The consistently smaller [1-NP]/[Pyr] ratio and larger [6-NBaP]/[BaP] ratio in Kitakyushu suggests that the major contributor of PAHs was not automobiles but iron manufacturing which uses a large amount of coal. The sudden increase in atmospheric PAH concentrations in the winter of 2014 may also be due to iron manufacturing. Copyright © 2017 Elsevier Ltd. All rights reserved.

However, this procedure is sometimes difficult and can be dangerous for elderly patients whose abdominal fat layer is thin because of malnutrition. In such cases, alternative diagnostic methods are required. We report three elderly patients with heart failure complicated by malnutrition. In all cases, electrocardiogram showed low voltage in the limb leads and a pseudoinfarct pattern in the chest leads, and echocardiography showed left ventricular wall thickening with granular sparkling appearance. These patients were suspected of having amyloid cardiomyopathy but could not undergo myocardial biopsies because of their poor conditions. After failed attempts at biopsy of the abdominal fat pad or the other organs, subcutaneous fat tissue biopsy over the hip led to the diagnosis of systemic amyloidosis with cardiomyopathy. The resultant diagnosis guided us to choose the appropriate treatment for the patients. This article illustrates that subcutaneous fat tissue biopsy of the hip could be a useful procedure for diagnosing systemic amyloidosis in elderly patients, particularly when a fat tissue biopsy of the abdomen is associated with a high risk of complications because of malnutrition.

However, the usefulness of combination therapy with a selective neutrophil elastase inhibitor, sivelestat, and recombinant human soluble thrombomodulin (rhTM for patients with ARDS and DIC remains unknown. Methods: We conducted a retrospective data analysis of 142 ARDS patients with DIC to assess the effects of sivelestat combined with rhTM. Patients were divided into four groups: control (no sivelestat or rhTM treatment, sivelestat treatment alone, rhTM treatment alone, and combined treatment with sivelestat and rhTM. A Cox proportional hazard model was used to assess subject mortality rates. The efficacy of these drugs was evaluated based on survival rate, number of ventilator-free days, and change in PaO2/FIO2 (P/F ratios and DIC scores before and at 7 days after a diagnosis of ARDS with DIC. Results: Multivariate analysis showed that patient age, combination therapy, gas exchange, organ failure, cause, associated disease score, and serum C-reactive protein levels were predictors of mortality for patients with ARDS and DIC. As compared with untreated controls, combination therapy significantly improved the 60-day survival rate of patients with ARDS and DIC

This study aimed to develop a profile scoring system for assessing the psychosocial situation of patients with chronic musculoskeletal pain. An expert panel chose social and psychological domains considered to be relevant to patients with chronic pain and wrote questions asking about each of those domains. The questionnaire was completed by 252 patients with chronic musculoskeletal pain. Factor analysis was used to select questionnaire items for each domain. Associations and interactions of pain severity and each domain score with pain-related quality of life (PRQOL were examined using linear regression models. Five domains were chosen: work, family, sleep, mental health, and PRQOL. Then, a total of 17 questions were created for the work, family, and sleep domains. Using the likelihood-ratio test, we found significant interactions with PRQOL in four pairs: severity–family, severity–mental, family–sleep, and work–mental.

The aim of this study was to investigate the relationship between the severity of obsession or compulsion and schizotypy in OCD.Patients and methods: Sixty subjects (25 males and 35 females who were OCD outpatients in the University Hospital at the Kyoto Prefectural University of Medicine during the period 2008–2010 were enrolled in the study. Assessments of these patients were made using the Yale–Brown Obsessive Compulsive Scale (Y-BOCS, the Schizotypal Personality Questionnaire (SPQ, the Hamilton Depression Rating Scale (HAM-D, and the Hamilton Anxiety Rating Scale (HAM-A. The Pearson correlation coefficients between Y-BOCS and SPQ scores were calculated. Furthermore, hierarchical multiple linear regression analyses were conducted to assess whether schizotypy predicted the severity of obsession and compulsion.Results: By calculating the Pearson correlation coefficient, it was found that the Y-BOCS obsession score, not the Y-BOCS compulsion score, was correlated with the SPQ total score. Results of the hierarchical multiple linear regression analysis showed that SPQ total score was a significant predictor of the Y-BOCS obsession score, after accounting for control

Physiological indicators such as blood pressure, percutaneous oxygen saturation, pulse, tympanic temperature, and sleep time and efficiency were assessed. Cognitive function and behavioral and psychological symptoms of dementia were assessed using the Mini-Mental State Examination, Dementia Mood Assessment Scale, and Dementia Behavior Disturbance scale.Results: Significant decreases in systolic (P < 0.01 and diastolic blood pressure (P < 0.05 along with a significant increase in tympanic temperature (P < 0.01 were observed after the steam foot spas. A significant improvement was seen in the Mini-Mental State Examination score (P < 0.01 and the overall dementia severity items in Dementia Mood Assessment Scale (P < 0.05.Limitations: Japanese people are very fond of foot baths. However, it is difficult to understand why inpatients cannot receive steam foot baths. In this study, a control group was not used. Raters and enforcers were not blinded.Conclusion: The results of this pilot study suggest that steam foot spas mitigate cognitive impairment in geriatric inpatients.Keywords: steam foot spa, geriatric inpatients, cognitive impairment, tympanic temperature

    Does in vivo aging of mouse oocytes affect mitochondrial function? Mitochondrial function was impaired in post-ovulatory in vivo-aged mouse oocytes and microinjection of somatic cell mitochondria did not rescue poor fertilization and embryonic development rates. The mechanisms underlying the decline in oocyte quality associated with oocyte aging remain unknown, although studies have suggested that the decline is regulated by mitochondrial dysfunction. However, only a limited number of studies have provided direct evidence implicating mitochondrial dysfunction in oocyte quality during the aging of oocytes. We used post-ovulatory, in vivo-aged mouse oocytes as a model for studying low-quality oocytes in oocyte aging. Superovulated oocytes released from the oviduct at 14 h and 20-24 h post-hCG injection were designated as 'fresh' and 'aged' oocytes, respectively. Membrane potentials and oxygen consumption in single oocytes were evaluated as measures of mitochondrial function in fresh and aged oocytes. Mitochondrial transcriptional factor A (TFAM) expression levels were examined by western blotting, and colocalization of mitochondria and TFAM was analyzed by measuring immunofluorescence in fresh and aged oocytes. IVF and blastocyst formation rates were calculated after oocyte microinjection with mitochondria derived from liver cells. The average mitochondrial membrane potential in fresh oocytes was significantly higher than that in aged oocytes (P transfer of cytosolic factors or cellular organelles, such as the endoplasmic reticulum or mitochondria, from specific cell types.

The chronological changes in various factors, including patient’s age, sex, histological type, tumor size, pathological stage (p-stage, surgical method, operative time, intraoperative blood loss, 30-day mortality, and postoperative overall survival (OS, were evaluated.Results: A total of 1,616 patients were included. The numbers of resected patients, females, adenocarcinomas, p-stage IA patients, and age at the time of surgery increased with time, but tumor size decreased (all P<0.0001. Concerning surgical methods, the number of sublobar resections increased, but that of pneumonectomies decreased (P<0.0001. The mean operative time, intraoperative blood loss, and the postoperative 30-day mortality rate decreased (all P<0.0001. When the patients were divided into two groups (1974–2004 and 2005–2014, the 5-year OS rates for all patients and for p-stage IA patients improved from 44% to 79% and from 73% to 89%, respectively (all P<0.0001. The best 5-year OS rate was obtained for sublobar resection (73%, followed by lobectomy (60%, combined resection (22%, and pneumonectomy (21%; P<0.0001.Conclusion: Changes in epidemiological factors, a trend toward less invasive surgery, and a remarkably improved postoperative OS were confirmed, which demonstrated the increasingly important role of surgery in therapeutic strategies for lung cancer.

Biomedical applications of BN have recently started to emerge, raising great hopes in drug and gene delivery. Here, we developed a targeted anticancer drug delivery system based on folate-conjugated BN nanospheres (BNNS with receptor-mediated targeting. Folic acid (FA was successfully grafted onto BNNS via esterification reaction. In vitro cytotoxicity assay showed that BNNS-FA complexes were non-toxic to HeLa cells up to a concentration of 100 µg/mL. Then, doxorubicin hydrochloride (DOX, a commonly used anticancer drug, was loaded onto BNNS-FA complexes. BNNS-FA/DOX complexes were stable at pH 7.4 but effectively released DOX at pH 5.0, which exhibited a pH sensitive and sustained release pattern. BNNS-FA/DOX complexes could be recognized and specifically internalized by HeLa cells via FA receptor-mediated endocytosis. BNNS-FA/DOX complexes exhibited greater cytotoxicity to HeLa cells than free DOX and BNNS/DOX complexes due to the increased cellular uptake of DOX mediated by the FA receptor. Therefore, BNNS-FA complexes had strong potential for targeted cancer therapy. Keywords: boron nitride nanospheres, folic acid, doxorubicin, targeted delivery, cancer therapy

As everolimus (EVR is effective for preventing calcineurin inhibitor (CNI nephrotoxicity without increasing the risk of chronic rejection and viral infection, we aimed to assess the efficacy of EVR in ABOi KT.Patients and methods: We retrospectively studied 22 patients who underwent KT and received EVR. Patients in the ABOi KT group (n=7 were compared with those in the ABO-compatible kidney transplantation group (ABOc KT; n=15. We recorded the frequency of CNI nephrotoxicity, chronic rejection, and viral infection in the 2 groups.Results: CNI nephrotoxicity, chronic rejection, and viral infection occurred in the ABOi KT and ANOc KT groups at rates of 28.3% (2/7 patients and 13.3% (2/15 patients (P=0.388, 28.3% (2/7 patients and 26.7% (4/15 patients (P=0.926, and 14.3% (1/7 patients and 26.7% (4/15 patients (P=0.517, respectively.Conclusion: Administration of EVR is effective in preventing CNI nephrotoxicity after KT. The rate of CNI nephrotoxicity was lower in the ABOc KT group than in the ABOi KT group. The rate of chronic rejection and viral infection was comparable between the groups. This study was conducted in a small cohort of patients. Hence, further evaluation with large sample sizes is necessary in the future to confirm the outcomes.

It was introduced to Japan in the middle of the sixth century and has evolved over the past 1,400 years after combining with Japan’s original folk remedies. While it retains some similarities to TCM, Kampo has evolved in Japan, resulting in a system of medicine that has many differences from TCM. Kampo medicine is considered to be very safe; in Japan, Kampo herbal formulas are manufactured by licensed pharmaceutical companies, prescribed by Western-trained medical doctors (usually as a freeze-dried extract, and have quality control standards similar to those of prescription drugs. The present study examined Yokukan-san (Yi-Gan San in TCM, a Kampo formula that has been used empirically in Japan for more than 400 years. Accumulating clinical trials have demonstrated Yokukan-san’s efficacy in treating patients with behavioral and psychological symptoms of dementia, which has resulted in the Japanese Society of Neurology listing it in the Japanese Guidelines for the Management of Dementia 2010. Efficacy in other diseases and conditions, such as sleep disorders, tardive dyskinesia, aggression, and impulsivity has also been reported.

    Environmental changes recorded in the shell nacre of Sinohyliopsis schlegeli were observed with elemental factors of characteristic water and nutrition for eight months in a cultivated drainage pond at Kanazawa University, Ishikawa Prefecture, Japan. Tetracycline as an indicator was injected into the shell nacre once every month from May to November in 2007. Water qualities such as the pH, redox potential, electrical conductivity, dissolved oxygen concentration, and water temperature were measured periodically, and the suspended solids in the water were removed by filtration for optical microscopy, X-ray fluorescence analysis, and scanning electron microscopy-energy dispersive X-ray (SEM-EDX) observations. X-ray fluorescence chemical analysis of shell nacre indicated layers with strong tetracycline accumulation corresponding to high concentrations of Si, Mn, Fe, and Sr ions. The redox potential and dissolved oxygen concentration measurements supported the existence of layers in the nacre. The suspended materials in the drainage pond water comprised mainly of Si, Mn, and Fe elements, which were the same elements involved in microbial immobilization in the shell nacre during the summer of 2007. SEM-EDX analyses confirmed that the ions originated from diatoms, Siderocapsa sp. and Gallionella ferruginea in the stomach. There was little microbial immobilization of the ions in winter. The results suggested elemental immobilization in the layered shell nacre and indicated that Sinohyliopsis schlegeli fed on the ions, to grow the nacre during summer. Sinohyliopsis schlegeli with these biogenic oxides might contribute to the scavenging of heavy metals in natural water.

    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.

    Full Text Available In Japan, regional shopping districts are on the decline because residents prefer suburban-type large-scale shopping stores. Such issues can be addressed in the context of the “Smart City”, of which functions depend on the information and communication technology (ICT. We established the “KIT Digital Signage Project,” which aims to help the regional stores around the Kanazawa Institute of Technology (KIT. In our project, we developed a digital signage system that is low-cost and easy to introduce in small stores. We conducted an experiment to evaluate the effect of our system. During the experiment, store-advertising movies were shown on digital signage terminals, which were placed in each store. The total average watching time and audience rate of our system were 24 s and 50%, respectively. In addition, we investigated the educational aspects of our project. The students in our project could master movie production in a shorter time when compared against learning it as an ordinary classroom subject. The future plans of our project are also discussed.

    We intravenously administered flomoxef sodium (FMOX) 120 minutes before cataract surgery, topically administered levofloxacin (LVFX) into the eyes four times at 30-minute intervals before surgery, and measured the aqueous humor concentrations of these agents to investigate their penetration into the aqueous humor and their efficacy in the prevention of postoperative endophthalmitis. Sixty-eight patients who underwent cataract surgery at the Department of Ophthalmology, Yokohama City University School of Medicine, or its affiliate, Kanazawa Hospital, Yokohama, were enrolled in this study. They received one or both of the following: 1.0 g FMOX via a 20-minute intravenous drip and LVFX ophthalmic solution applied four times at 30-minute intervals, both beginning two hours before the operation. Aqueous humor was aspirated from the anterior chamber and assayed for FMOX and LVFX concentrations using high-performance liquid chromatography (HPLC). The mean intraoperative FMOX and LVFX concentrations in the patients' aqueous humor were 1.21 +/- 0.63 microg/ml and 0.69 +/- 0.47 microg/ml, respectively. These concentrations sufficiently exceeded the MIC90 values against Staphylococcus epidermidis, S. aureus, and Propionibacterium acnes. The FMOX and LVFX concentrations in the aqueous humor sampling were adequate to kill bacteria in vitro. These drugs may have efficacy in the prevention of postoperative endophthalmitis in patients undergoing cataract surgery.

    Bone metastasis symptoms are complications that greatly reduce the quality of life (QOL) of cancer patients. We report a retrospective study on the efficacy of radiation therapy for patients with bone metastasis in urinary organ cancer. (Subjects and methods) Subjects are comprised of 17 patients; total irradiated areas consist of 25 sites. There are 5 patients diagnosed with renal cell carcinoma, 1 patient with bladder cancer and 11 patients with prostatic cancer. All of them have undergone radiation therapy for bone metastasis in urinary organ cancer between April 2007 and March 2014 in the Department of Urology, Kanazawa Medical University. The mean age of the patients was 66.7 years old. We looked at irradiated areas, exposure dose and changes of symptom in all patients. Irradiated areas are thoracolumbar vertebrae (14 sites), cranial base (2 sites), pubic bone (1 site), ilium bone (2 sites), sacral bone (1 site), rib bone (1 site) and hip joint (1 site). The mean exposure dose of one area is 37.5 Gy (13.5-60). 19 irradiated sites which were previously reported to have sharp pain have gained improvement at 16 sites. These 16 sites have comparatively lesser pain or no pain. 8 cases in acknowledgment of walk difficulty, it was with 7 cases walking alone possibility again. This study showed that radiation therapy have significant improvement in terms of symptoms and QOL for the patients with bone metastasis in urinary organ cancer. (author)

    The concentration of Pb-210 and Po-210 in the surface air of volcanic areas is of considerable interest from the viewpoints of geochemistry, geophysics and also health physics, because these nuclides are the useful tracers for the estimation of the residence time or life time of aerosols, and give the significant radiation dose due to inhalation and ingestion through food stuffs. Since the establishment of Low Level Radioactivity Laboratory, Kanazawa University, in 1976, the measurement of environmental radioactivity has been one of the main subjects, and the measurement of Pb-210 and Po-210 in the surface air of Kagoshima was begun in 1987 to estimate the contribution from Volcano Sakurajima. In this study, the measurement of Pb-210 and Po-210 in air borne particles collected with air samplers, volcanic ash and lava of volcano Sakurajima of which the age of eruption is known. Moreover, the Po-210 in the volcanic gas and sulfur sublimate in the samples collected in four active volcanoes in Hokkaido was measured. The experiment and the results are reported. (K.I.)

    K-Ar and zircon fission-track dating was carried out on some granitic rocks in the Hida Range, central Japan. The samples analyzed were collected on both sides of one of the major faults in the Hida Range: the Kurobe-Takase fracture zone. Ages obtained west of the fault are ∼60 Ma, while those obtained to the east of the fault are less than ∼5 Ma. These results indicate a remarkable age difference across the fault. The Okukurobe granite, located west of the fault, cooled rapidly from ∼600degC to ∼240degC between 60-55 Ma, and the Kanazawa granodiorite, located east of the fault, cooled rapidly from ∼600degC to ∼240degC between 5-1 Ma. The Okukurobe granite has remained cooler than ∼240degC since ∼55 Ma. Thus, it was found that the granitic rocks across the fault have experienced a remarkable different cooling history. (author)

    Short-lived radionuclides with halflives of a few 10 7 years, now-extinct in the solar system, are expected to be present in the interstellar medium (ISM) as freshly synthesized matter in supermovae. Grains of ISM origin recently discovered in the inner solar system and at Earth orbit may accrete onto Earth after ablation in the atmosphere. As pointed out by one of the authors (K.S.) in 1974, a favorable matrix of detection of such extraterrestrial material is deep-sea sediments with very low sedimentation rates of ∼1 mm.ky -1 . We report here a search for the 'live' Pu-244 in a 1 kg-deep-sea dry sediment collected in 1992 in the North Pacific. After a 546 day a-counting of a Pu fraction chemically separated from the alkaline-fused sediment sample at Kanazawa Univ. AMS analysis was performed at Hebrew Univ. and Weizmann Institute. Only one count of Pu-244 with no background ions was detected, indicating no excess over the expected stratospheric man-made fallout. A limit of 0.2 Pu-244 atoms cm -2 .y -1 for extra terrestrial deposition was set under reasonable assumptions and it was then concluded from this result and the available data on ISM that the abundance of Pu-244 in the ISM is less than 2 X 10 -11 g-Pu-244 (g ISM) -1 . Implications of the present result will be discussed.

    HMGB1 is an evolutionarily conserved non-histone chromatin-associated protein with key roles in maintenance of nuclear homeostasis; however, the function of HMGB1 in the brain remains largely unknown. Recently, we found that the reduction of nuclear HMGB1 protein level in the nucleus associates with DNA double-strand break (DDSB)-mediated neuronal damage in Huntington's disease [M.L. Qi, K. Tagawa, Y. Enokido, N. Yoshimura, Y. Wada, K. Watase, S. Ishiura, I. Kanazawa, J. Botas, M. Saitoe, E.E. Wanker, H. Okazawa, Proteome analysis of soluble nuclear proteins reveals that HMGB1/2 suppress genotoxic stress in polyglutamine diseases, Nat. Cell Biol. 9 (2007) 402-414]. In this study, we analyze the region- and cell type-specific changes of HMGB1 and DDSB accumulation during the aging of mouse brain. HMGB1 is localized in the nuclei of neurons and astrocytes, and the protein level changes in various brain regions age-dependently. HMGB1 reduces in neurons, whereas it increases in astrocytes during aging. In contrast, DDSB remarkably accumulates in neurons, but it does not change significantly in astrocytes during aging. These results indicate that HMGB1 expression during aging is differentially regulated between neurons and astrocytes, and suggest that the reduction of nuclear HMGB1 might be causative for DDSB in neurons of the aged brain

    By law, medical faculties are mandated to have a designated partner hospital for the purposes of student practical training. In contrast, pharmacy faculties do not have such a legal requirement for student training in a community pharmacy setting. Nevertheless, there are several public and private universities that do have community pharmacies. However, there is no national university that has established both an educational hospital and a community pharmacy. When Kanazawa University (KU) established a graduate school with a clinical pharmacy course, the faculty of KU deemed it necessary to set up an independent community pharmacy for the purpose of practical training. Thus, in 2003, the Acanthus Pharmacy was set up as the first educational community pharmacy in Japan, managed by a nonprofit organization, with the permission of the Ishikawa Pharmaceutical Association and local community pharmacists. Since that time, Acanthus has managed a clinical pharmacy practice for students from both the undergraduate and graduate schools of KU. From 2006, the undergraduate pharmacy program was changed to a 6-year program, and the Acanthus Pharmacy has continued its roles in educating undergraduate pharmaceutical students, medical students, and as a site of early exposure for KU freshmen. From our experience, it is important to have a real clinical environment available to university pharmacy faculty and students, especially in training for community pharmacy practices.

  2. Why do very unattractive workers earn so much?

    Kanazawa and Still (2018) showed that very unattractive workers earned more than unattractive workers, sometimes more than average-looking or attractive workers, because they had higher levels of intelligence and education, but they did not explain why very unattractive workers had higher intelligence and education. There are both theoretical and empirical reasons to expect that some intelligent men may prefer to marry very unattractive women. The analysis of the National Longitudinal Study of Adolescent Health (Add Health) shows that very unattractive women were significantly more likely to be married at Age 29 than unattractive or average-looking women, and their spouses or partners earned significantly more than those of unattractive or average-looking women. If intelligent men have historically preferred to marry very unattractive women generation after generation, then, because both general intelligence and physical attractiveness are highly heritable, this can explain why very unattractive workers are more intelligent and achieve higher education, thereby earning more. It can also explain why the positive correlation between intelligence and physical attractiveness is not larger despite assortative mating of intelligent men of higher status and physically attractive women over many generations.

    Concentrations of organically-bound 14 C in the tree-ring cellulose of a Japanese Cedar (Cryptomeria japonica) grown in a rural region of Kanazawa, Ishikawa prefecture, Japan (36.5degN, 136.7degE), were measured for the ring-years from 1989 to 1998 to study relationship between 14 C concentrations in tree-ring cellulose and atmospheric CO 2 in a narrow region. An interesting result in comparing our data of tree-ring cellulose with those of atmospheric CO 2 is that the 14 C concentration in tree-ring cellulose was close to the corresponding average from mid-June to early September of 14 C concentrations in atmospheric CO 2 . Furthermore, the 14 C concentrations in tree-ring cellulose were found to be merely influenced by the drastic decrease of 14 C concentrations in atmospheric CO 2 in winter, which might be caused by air pollution from the Asian continent and additional local fossil fuel contribution. These results suggest that the 14 C concentration in tree-ring cellulose for a given growing year reflects the 14 C concentrations of atmospheric CO 2 during the warm summer months. (author)

    The neutron criticality accident at the JCO, a private company for nuclear fuel processing facilities in Tokai has drastically changed minds and attitudes of residents toward environmental radioactivity. The accident happened on September 30, 1999. Before the accident the residents of the Rokkasho Site were not anxious about environmental radioactivity, because they thought the facilities were safe enough concerning containment policy of the radioactivity inside the facilities. Residents, however, had not been taught on a neutron. It is an unfamiliar radiation for them. So, they promptly learnt on neutrons, and some of them began the fixed point measurement of neutrons at the nearest site of the Spent Fuel Recycling Facilities of Rokkasho by the help of Prof. Kazuhisa. Komura, Kanazawa University. Members of the Reading Cicle, Rokkasho Culture Society, mainly women, learnt measurements of environmental radioactivity using simplified counters for alpha-, beta-, and gamma-ray from natural radioactive elements and prepared various kinds of environmental samples. After learning of environmental radioactivity, they began educational activities on the environmental radioactivity for boys and girls in the region. Monitoring of environmental radioactivity is performed by different institutions and with their purposes. Here is reported learning of environmental radioactivity by the residents and education of environmental radioactivity toward the young. Even with the simplest counters, we think that the monitoring of environmental radioactivity by the residents themselves is the royal road to the safety of the regional society. (author)

    In this paper, a new method for determining the rheological parameters of viscoelastic liquids is presented. To this end, we used the perturbation method applied to shear vibrations of cylindrical piezoceramic resonators. The resonator was viscoelastically loaded on the outer cylindrical surface. Due to this loading, the resonant frequency and quality factor of the resonator changed. According to the perturbation method, the change in the complex resonant frequency deltaomega = deltaomega(re) + jdeltaomega(im) is directly proportional to the specific acoustic impedance for cylindrical waves Zc of a viscoelastic liquid surrounding the resonator, i.e., deltaomega is approximately equal to jZc, where j = (-1)1/2. Hence, the measurement of the real and imaginary parts of the complex resonant frequency deltaomega determines the real part, Rc, and imaginary part, Xc, of the complex acoustic impedance for cylindrical waves Zc of an investigated liquid. Furthermore, the specific impedance ZL for plane waves was related to the specific impedance Zc for cylindrical waves. Using theoretical formulas established and the results of the experiments performed, the shear storage modulus mu and the viscosity eta for various liquids (e.g., epoxy resins) were determined. Moreover, the authors derived for cylindrical resonators a formula that relates the shift in resonant frequency to the viscosity of the liquid. This formula is analogous to the Kanazawa-Gordon formula that was derived for planar resonators and Newtonian liquids.

    Twenty-five cases with thymoma were treated in the department of Radiology of Kanazawa University from January, 1968 to December, 1981. All the patients recieved radiation therapy with or without operation. The effects of radiotherapy for thymoma were studied. The results and conclusions obtained were as follows; 1) Eight cases with stage III that recieved irradiation postoperatively, six of the eight cases showed the local control within the period between six months to seven years, excluding other two cases in which occurred the mediastinal and pleural disseminations. Therefore postoperative irradiation of 40- 50 Gy/4-5 weeks is considered to be necessary in stage III cases. 2) In 11 inoperable advanced cases, seven cases showed marked tumor regression on chest X-ray film and five cases showed the local control within the period between nine months and four years two months. Therefore long term survival may be possible if curative irradiation of 50-60 Gy/5-6 weeks is given for inoperable cases. 3) Concerning the cause of death, the mediastinal and pleural disseminations were very common, and local tumor progression, respiratory insufficiency by myasthenia gravis and distant metastasis were less common.

    The concentration of Pb-210 and Po-210 in the surface air of volcanic areas is of considerable interest from the viewpoints of geochemistry, geophysics and also health physics, because these nuclides are the useful tracers for the estimation of the residence time or life time of aerosols, and give the significant radiation dose due to inhalation and ingestion through food stuffs. Since the establishment of Low Level Radioactivity Laboratory, Kanazawa University, in 1976, the measurement of environmental radioactivity has been one of the main subjects, and the measurement of Pb-210 and Po-210 in the surface air of Kagoshima was begun in 1987 to estimate the contribution from Volcano Sakurajima. In this study, the measurement of Pb-210 and Po-210 in air borne particles collected with air samplers, volcanic ash and lava of volcano Sakurajima of which the age of eruption is known. Moreover, the Po-210 in the volcanic gas and sulfur sublimate in the samples collected in four active volcanoes in Hokkaido was measured. The experiment and the results are reported. (K.I.).

    1998-08-01

    This is a review on the previous researches for the vibration of fuel rod induced by axial flow. The analysis methods are classified into three categories accordingly as the researchers postulate the vibration to be self-excited, forced and parametric; the self-excited mechanism by Burgreen and Quinn, the forced one by Reavis, Gorman, kanazawa, and S. Chen, and the parametric one by Y. Chen. Quinn supposed that the centrifugal force by flow exaggerated the natural bow in the cylinder, and the flexural force by it diminished the bow by turns; this interactive motion leaded cylinder to vibration. The supporters to the forced mechanism considered the forces arising from pressure perturbation within the boundary layers as vibrating sources. Y. Chen insisted that the cylinder could only be excited to vibration in resonance by the small oscillation of mean flow velocity. The previous studies were based on the simple boundary conditions such as hinged-hinged or fixed-fixed single span. Therefore, for the more accurate prediction of the fuel rod vibration in reactor, the further studies need to reflect the actual boundary conditions of the fuel rod like axial force and continuous supports by grids.

    Full Text Available CD157, also referred to as bone marrow stromal cell antigen-1 (BST-1, is a glycosylphosphatidylinositol-anchored molecule that promotes pre-B-cell growth. Previous studies have reported associations between single-nucleotide polymorphisms (SNPs of the CD157/BST1 gene with Parkinson’s disease. In an attempt to determine whether SNPs or haplotypes in the CD157/BST1 are associated with other brain disorders, we performed a case-control study including 147 autism spectrum disorder (ASD patients at Kanazawa University Hospital in Japan and 150 unselected Japanese volunteers by the sequence-specific primer-polymerase chain reaction method combined with fluorescence correlation spectroscopy. Of 93 SNPs examined, two SNPs showed significantly higher allele frequencies in cases with ASDs than in unaffected controls (rs4301112, OR = 6.4, 95% CI = 1.9 to 22, p = 0.0007; and rs28532698, OR = 6.2, 95% CI = 1.8 to 21, p = 0.0012; Fisher’s exact test; p < 0.002 was considered significant after multiple testing correction. In addition, CT genotype in rs10001565 was more frequently observed in the ASD group than in the control group (OR = 15, 95% CI = 2.0 to 117, p = 0.0007; Fisher’s exact test. The present data indicate that genetic variation of the CD157/BST1 gene might confer susceptibility to ASDs.

    Many countries are presently concerned with problems relating to the safe disposal of nuclear waste containing various levels of transuranium nuclides. In this context, a review on the distribution and behaviour of transuranium elements in the environment studied at Kanazawa University in Japan is presented. About 17 years ago, a high degree of accumulation of 239 Pu in the surface soil of Nagasaki was found in the Nishiyama area, where 'black rain' occured just after the nuclear bomb explosion. The introduction of newly developed radiochemical methods and instrumentation has enabled studies to be carried out on environmental plutonium isotopes, americium-241 and more recently neptunium-237 with respect to distribution depth profile, variation with time and relationship with organic materials. Valuable information has been obtained on the basis of samples collected from various locations in Japan, including surface soil, sea and lake sediments, atmospheric aerosol, water from the Japan Sea and the Pacific Ocean, and from material related with the 'Bikini Event' of 1954.

    I discus the experience at Kanazawa University Hospital with the newer imaging methods (RI, US, CT) and how they have influenced the angiographic workup of patients with hepatic mass. Hepatic angiography is no longer performed a diagnosis of hepatic cyst and the US has been valuable for it. The combination of CT or US, and AFP has been associated with the decrease in the number of hepatic angiography for the advanced hepatoma. In contrast to the advanced, angiography has to be performed actively to demonstrate the small foci for the patient with a strong clinical suspicion. The conventional celiac angiography and hepatic angiography were not always able to detect small foci measuring less than 2 cm in diameter, due to vascular proliferation which cannot be distinctly identified by conventional angiography. In these cases infusion hepatic angiography enhanced the detection of the foci. We routinely rely on CT as a valuable supplement prior to surgical management, for obtaining more exact information as to the extent of hepatoma. The dynamic CT with bolus injection enables us to make exact diagnosis of cavernous hemangioma of the liver without performing of hepatic angiography. Also CT arteriography and dynamic CT have the advantage over the conventional CT in the correct diagnosis of small hepatoma. (author)

    High resolution (2-3 hrs) simultaneous measurements of airborne radionuclides, 212 Pb, 210 Pb and 7 Be, have been performed by using extremely low background Ge detectors at Ogoya Underground Laboratory. We have measured above radionuclides at three monitoring points viz, 1) Low Level Radioactivity Laboratory (LLRL) Kanazawa University, 2) Shishiku Plateau (640 m MSL) located about 8 km from LLRL to investigate vertical difference of activity levels, and 3) Hegura Island (10 m MSL) located about 50 km from Noto Peninsula in the Sea of Japan to evaluate the influences of Asian continent or mainland of Japan on the variation to the activity levels. Variations of short-lived 212 Pb concentration showed noticeable time lags between at LLRL and at Shishiku Plateau. These time lags might be caused by change of height of a planetary boundary layer. On the contrary, variations of long-lived 210 Pb and 7 Be showed simultaneity at three locations because of homogeneity of these concentrations all over the area. (author)

Evaluations included changes in total dysmenorrhea score, visual analog scale for dysmenorrhea, severity of symptoms, hormone levels, endometrial thickness, and safety outcomes. In both studies, the total dysmenorrhea score was significantly (P<0.001 decreased from baseline during treatment with EE/DRSP. Time-dependent changes in visual analog score for dysmenorrhea and alleviation of symptoms, such as lower abdominal pain, low back pain (lumbago, headache, and nausea/vomiting, were similar in all patient groups with and without any specific coexisting organic diseases. These improvements with EE/DRSP were observed for both short-term (16 weeks and long-term (52 weeks use.

As yokukan-san has become broadly integrated with conventional medicine, augmentation therapy with other Kampo prescriptions has become necessary when the yokukan-san has been only partially efficacious. In this paper, we report three cases in which the addition of orengedoku-to, another Kampo formula, to yokukan-san was remarkably effective.Cases: Case 1 was an 85-year-old man with Alzheimer-type dementia who had become aggressive during the past 2 years. Three milligrams of aripiprazole completely suppressed his problematic behaviors but had to be stopped because of extrapyramidal symptoms. In the second case, a 44-year-old man with methamphetamine-induced psychosis had suffered from serious tardive dystonia for 2 years. No conventional approach had improved his tardive dystonia. The third case was a 29-year-old engineer who often failed to resist aggressive impulses and was diagnosed with intermittent explosive disorder. He was prescribed 5 mg of olanzapine, which did not suppress his extraordinary anger and caused somnolence even though the dose was low.Interventions and outcomes: Yokukan-san was complementarily added to the patients' regular medication and exerted a definitive but partial effect in all cases. The addition of orengedoku-to to yokukan-san exerted the same efficacy as aripiprazole in controlling aggressiveness in Case 1

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

Computed tomography (CT-detected pulmonary artery (PA enlargement is independently associated with acute COPD exacerbations. Associations between PA to aorta (PA:A ratio and EID in patients with COPD have not been reported. We hypothesized that the PA:A ratio correlated with EID and that results of the 6-minute walk test (6MWT would be useful for predicting the risk associated with PA:A >1.Patients and methods: We retrospectively measured lung function, 6MWT, emphysema area, and PA enlargement on CT in 64 patients with COPD. The patients were classified into groups with PA:A ≤1 and >1. Receiver-operating characteristic curves were used to determine the threshold values with the best cutoff points to predict patients with PA:A >1.Results: The PA:A >1 group had lower forced expiratory volume in 1 second (FEV1, forced vital capacity (FVC, FEV1:FVC ratio, diffusion capacity of lung carbon monoxide, 6MW distance, and baseline peripheral oxygen saturation (SpO2, lowest SpO2, highest modified Borg scale results, percentage low-attenuation area, and history of acute COPD exacerbations ≤1 year, and worse BODE (Body mass index, airflow Obstruction, Dyspnea, and Exercise index results (P<0.05. Predicted PA:A >1 was determined for SpO2 during 6MWT (best cutoff point 89%, area under the curve 0.94, 95% confidence interval 0.88–1. SpO2 <90% during 6MWT showed a sensitivity of 93.1, specificity of 94

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%]. No patients developed dependence on nalfurafine. Nalfurafine was effective in 82.50% (2,880/3,491 of patients during the first 12 weeks and in 84.95% (2,167/2,551 on treatment during the subsequent period until 1 year after nalfurafine treatment initiation.

We aimed to establish the time of highest death risk during TB treatment, and to identify the risk factors taking place during that period of high risk.Patients and methods: We explored the TB surveillance data of the Chiang Rai province, Northern Thailand, retrospectively for 12 years. A total of 19,174 TB patients (including 5,009 deaths were investigated from 1997 to 2008, and the proportion of deaths in each month of TB treatment was compared. Furthermore, multiple logistic regression analysis was performed to identify the characteristics of patients who died in the first month of TB treatment. A total of 5,626 TB patients from 2005 to 2008 were included in this regression analysis.Result: The numbers of deaths in the first month of TB treatment were 38%, 39%, and 46% in the years 1997–2000, 2001–2004, and 2005–2008, respectively. The first month of TB treatment is the time of the maximum number of deaths. Moreover, advancing age, HIV infection, and being a Thai citizen were significant factors contributing to these earlier deaths in the course of TB treatment.Conclusion: Our findings have pointed to the specific time period and

    The author, a former American chemistry professor, has organized his book into nine parts with 29 chapters, covering, in a fairly historical sequence and systematic conceptual progression, all fundamentals of today's physics: i.e., mechanics, thermodynamics, electromagnetism, statistical mechanics, relativity, quantum mechanics, nuclear physics, particle physics, astronomy-astrophysics-cosmology. Obviously, the 20th century (when about 90% of professional physicists of all time worked) assumes with five topics the dominant role in this enterprise. For each topic, a small number (ranging from one to eight) of leading personalities is selected and the biographies of these 29 physicists, including two women (Marie Curie and Lise Meitner), are presented in some detail together with their achievements in the particular topic. Important relevant contributions of other scholars to each topic are also discussed. In addition, Cropper provides each of the topics with a short 'historical synopsis' justifying his selection of key persons. One may argue that concentrating on leading physicists constitutes an old-fashioned approach to displaying the history and contents of fundamental topics in physics. However, the mixture of biographies and explanation of leading contributions given here will certainly serve for a larger public, not just professional physicists and scientists, as a guide through the exciting development of physical ideas and discoveries. In general, the presentation of the material is quite satisfactory (with only few slips, e.g., in the Meitner story, where the author follows too closely a new biography) and gives the essence of the great advances in physics since the 15th century. One notices perhaps the limitation of the author in cases where no biography in English is available - this would also explain the omission of some of the main contributors to atomic and particle physics, such as Arnold Sommerfeld and Hideki Yukawa, or that French or Russian

In order to improve adherence by providing information about AD and the significance of pharmacotherapy, the Donepezil Outpatient Consultation Service (DOCS was set up. The influence of this service on medication persistence was assessed in the present study.Methods: Among outpatients starting donepezil therapy, we enrolled 59 patients between April 2008 and September 2010 before establishment of the DOCS (non-DOCS group and 52 patients between October 2010 and March 2012 who attended the DOCS (DOCS group. Each patient's and their caregiver's understanding about the clinical features of AD and pharmacotherapy with donepezil were also assessed. Their understanding was compared before and after the DOCS, and the 1-year medication persistence rate and the reasons for discontinuation were also investigated.Results: The 1-year medication persistence rate was significantly higher in the DOCS group than in the non-DOCS group (73

    Free-ranging raccoon dogs (Nyctereutes procyonoides) from Nogeyama Zoological Gardens, Kanazawa Zoological Gardens, and Yokohama Zoological Gardens frequently rescued dogs having Sarcoptes scabiei infestation. However, the epidemiology of S. scabiei infestation has not yet been elucidated. In the present study, we investigated the epidemiology of S. scabiei infestation in raccoon dogs and its influence on the population of masked palm civets in Yokohama, Japan. We examined records of raccoon dog rescue between 1981 and 2010 and classified the dogs into the following 4 categories on the basis of the reason for rescue: dogs with S. scabiei infestation, scabies-infested dogs involved in car accidents, uninfested dogs involved in car accidents, and other reasons for rescue. We found that the number of dogs rescued due to car accidents and other reasons increased from 1989 onwards, and an S. scabiei outbreak was recorded since 1993. The infestation spread from the southern to the northern regions of Yokohama. The total number of raccoon dogs rescued annually peaked in 1995 and declined thereafter. The number of masked palm civets (Paguma larvata) rescued gradually increased with a decline in the number of raccoon dogs rescued. In the present study, we revealed the epidemiology of S. scabiei infestation in the raccoon dog. The outbreak might be induced by the increased population density, and the infestation spread immediately from the southern to the northern regions of Yokohama since 1993. Further, the population of masked palm civets may have increased due to the decrease in the population of the raccoon dog. Copyright © 2012 Elsevier B.V. All rights reserved.

Cognitive remediation therapy (CRT aims to improve such cognitive processing; however, there are no reports on CRT for patients with ASD. This pilot study aimed to provide preliminary evidence to support the use of CRT for individuals with ASD and provide data to inform future studies.Participants and methods: Nineteen individuals with ASD were recruited and administered a series of neuropsychological and questionnaire measures to examine cognitive function and clinical outcomes such as anxiety and depression. Participants received CRT, and cognitive function and clinical variables were re-evaluated at postintervention and after 3 months.Results: The participants demonstrated significant improvement in CC and anxiety at postintervention, which was maintained at 3-month follow-up. Although SS scores had improved with a large effect size, this was not statistically significant.Conclusion: CRT improved CC and anxiety scores for individuals with ASD, suggesting that CRT is an effective treatment for individuals with ASD.

    Bladder cancer patients receiving methotrexate, vinblastine, adriamycin and cisplatin (MVAC) chemotherapy are co-administered with dexamethasone as an anti-emetic. We examined whether or not dexamethasone affects the severity and onset day of MVAC-induced severe neutropenia. This was a retrospective study of bladder cancer patients treated with MVAC chemotherapy with or without dexamethasone as an antiemetic at Kanazawa University Hospital during January 2005 - December 2009. Patients were categorized into three groups; no dexamethasone use (Dex (-)), dexamethasone on day 2 (Dex 1 day), and dexamethasone on days 2, 3 and 4 (Dex multiday). We evaluated the incidence of grade 3/4 neutropenia and the day of onset of first severe neutropenic episode during the first course of MVAC chemotherapy. Logistic regression was used to investigate whether co-administration of dexamethasone was a risk factor for severe neutropenia. Episodes of grade 3/4 neutropenia occurred in 3 out of 6 (50.0%), 11 out of 12 (91.7%) and 6 out of 6 (100%) patients in the Dex (-), Dex 1 day, and Dex multiday groups, respectively. The appearance day of first severe neutropenia in the Dex multiday group (13.2 ± 1.0) was significantly accelerated compared to the Dex (-) group (17.7 ± 2.1). Univariate logistic regression analysis revealed that dexamethasone is a risk factor for severe neutropenia (OR 17.0; 95%CI: 1.3-223.1). Co-administration of dexamethasone for anti-emesis brings forward the first appearance of neutropenia, and increases the severity of neutropenia, in bladder cancer patients receiving MVAC chemotherapy.

    Although of interest, few data exist on the clinical characteristics of Japanese patients with an extremely high triglyceride level (≥ 1000 mg/dL). We assessed the clinical characteristics of Japanese patients with an extremely high triglyceride level. We investigated the presence of coronary artery disease, history of pancreatitis, the presence of fatty liver, and the potential causes of elevated triglyceride in Japanese subjects with an extremely high level of fasting triglyceride (≥ 1000 mg/dL) among 70,368 subjects whose serum triglyceride was measured for any reason at Kanazawa University Hospital from April 2004 to March 2014. We identified 215 (0.31%) subjects (mean age, 46 years; male, 170, mean body mass index, 25 kg/m(2)) with severe hypertriglyceridemia. Among them, 4 (1.9%) subjects were classified as type I, 97 (45.1%) subjects were type IV, and 114 (53.0%) subjects were type V hyperlipidemia, according to Fredrickson's classification. Among 215 subjects, 116 subjects (54.0%) drank alcohol, 58 (27.0%) showed heavy intake (≥ 60 g/d), and 64 (29.8%) subjects had diabetes. In total, 59 (27.4%) subjects had transient severe hypertriglyceridemia caused by corticosteroids (N = 19), antidepressant (N = 18), l-asparaginase and steroids for acute lymphoid leukemia (N = 15), hormone replacement therapy for breast cancer (N = 9), β-blocker (N = 5), hypothyroidism (N = 4), pregnancy (N = 4), and panhypopituitarism (N = 2). As many as 119 (55.3%) subjects exhibited fatty liver. Moreover, 12 (5.6%) and 17 (7.9%) subjects had a history of pancreatitis and coronary artery disease, respectively. A variety of situations can cause severe hypertriglyceridemia. We suggest that potential secondary causes should be carefully assessed for such patients. Copyright © 2015 National Lipid Association.

    One of the application of ultra low-background gamma spectrometry, we tried to measure temporal variation of airborne radionuclides at intervals of 1 to few hours in extreme case. Airborne radionuclides were collected on a filter paper made of quartz fiber at the Low Level Radioactivity Laboratory (LLRL), Kanazawa Univ. in Tatsunokuchi (since Nov. 2002), Hegra Island located 50 km from Noto peninsula (since Apr. 2003) to investigate influence of Asian continent and Shishiku plateau at 640 m above sea to know vertical difference (since Sep., 2003). Pb-210, Pb-212 and Be-7 were measured nondestructively by ultra low background Ge detectors in Ogoya Underground Laboratory (270 meter water Concentration of Rn-222 was monitored 1 hour intervals and wind direction and speed were recorded 10 min or 2 min intervals (Hegra Is.) as support data in data analyses. In the regular monitoring, sampling was made at 1-2 day (LLRL and Shishiku) or 1 week intervals (Hegra) to know daily and seasonal variations and similarity or difference between sampling locations. When drastic meteorological change, such as passage of front or typhoon, occurrence of inversion layer and snow fall etc., short sampling at 1-2 hours of intervals was conducted to find the corrlation with meteorological factors at single point or 2 points simultaneously. As a results, it was found that concentrations of Pb-210, Po-210, Pb-212 and Be-7 were found to vary very quickly in a short time (see Figure below) due mainly to horizontal or vertical mixing of air-masses.

    Full Text Available The association between heavy metals exposure and respiratory diseases or allergic sensitization showing high serum immunoglobulin E (IgE has been suggested. However, previous findings have been inconsistent and the mechanisms responsible remain unclear. We evaluated heavy metal exposure and its association with coughing, itchy eyes in chronic cough patients with different IgE levels. Ninety outpatients in Kanazawa University Hospital were recruited between January–June 2011. Subjects whose total IgE measured by radioimmunosorbent test were asked to record their daily symptoms. We collected daily total suspended particles (TSP from which concentrations of calcium (Ca, cadmium (Cd, chromium (Cr, iron (Fe, manganese (Mn, nickel (Ni, and lead (Pb were determined then divided into high and low level groups. Generalized estimating equations were applied to compute the relationship between concentrations of these metals and symptoms. All metals at high levels were significantly associated with itchy eyes compared with low levels, with exception of Ca, the six others were significant in patients with IgE < 250 IU/mL. Cd, Fe, Mn had association with coughing (odds ratio-OR (95% confidence interval-CI: 1.13 (1.03, 1.24, 1.22 (1.05, 1.42, and 1.13 (1.01, 1.27, respectively, this relationship remained significant for Cd (OR (95% CI: 1.14 (1.03, 1.27 and Mn (OR (95% CI: 1.15 (1.00, 1.31 in patients with lower IgE. Our findings demonstrate the relationship between aerial heavy metals and itchy eyes, coughing in chronic cough patients, suggesting these symptoms may be due to a non-IgE mediated mechanism.

    The probe in the title launched in May 2003, landed on the asteroid 25143 (Itokawa) to collect the surface material, and returned to the desert of Australia in June 2010. The material carried in Japan Aerospace Exploration Agency (JAXA) was found to be >1,500 particles of extraterrestrial origin. This paper reports the results of activation analysis of a part of particles for the purpose of characterizing the elemental composition. The size of particles was mostly <100 mc-m and the mass, several 10s mc-g. The experiment was performed preliminarily on Kilabo meteorite using Kyoto University Research Reactor (KURR) as a neutron source, and then on 1 Itokawa particle named RA-QD02-0049, which was activated for 19 hr. The cooled particle was found to be split mainly in 2 parts (0049-1 and -2), which were subjected to analysis of gamma ray with Ge semiconductor detector in the KURR Institute and Kanazawa University. Analysis revealed that the 2 particles contained 8 elements of Na, Sc, Cr, Fe, Co, Ni, Zn and Ir, which were then quantitated with similarly neutron irradiated Allende meteorite, basalt JB-1 and highly purified Fe, and with previous findings by scanning electron microscope with energy dispersive X-ray spectrometer (SEM-EDX) showing the Itokawa particle was an olivine. Finally, 0049-1 and -2 were found to be of mass of 1.6 and 1.5 mc-g, respectively, based on which the calculated contents of the 8 elements revealed that they were homogeneously existed in the Itokawa particle. Comparison of elemental composition of the particle with those of various intra- and extra-terrestrial rocks and meteorites suggested that Itokawa had a feature of elements aggregated at the early stage after formation of the solar system 4.5 billion years ago.

    Spotty high intensity regions are frequently found on the MRI T2-weighted brain images (T2WI) of elderly people. High intensity regions with a diameter of 3 mm or less have been considered as expanded perivascular space with no pathological implications on radiological diagnosis. However, its morphometrical basis is not clear. We examined the character of the spotty regions using brain MRI of brain screening subjects, and studied morphometrically arteriolosclerosis and perivascular tissue damage using necropsy brains of subjects aged 65 years and over. The size, number and location of the spotty high intensity regions were examined using the brain MRI of 109 T2WI which is used for brain screening at Kanazawa Medical University Hospital. The frontal lobe, temporal lobe, parietal lobe, hippocampus, midbrain and basal ganglia were sampled from 15 subjects aged 65 years and over, and the tissue sections were processed for HE stain, Elastica van Gieson stain and immunostaining with GFAP. We took photographs of brain arterioli and surrounding parenchyma with a digital telescope camera and the degree of arterioscleosis and tissue damage were assessed by measurements with an image analyzer. Spotty high intensity regions on T2WI with a diameter of 3 mm or less were observed in 95.5% subjects aged 65 years and over. 69.4% spotty region was observed in basal ganglia. There was a significant correlation between age and size. In morphometrical examination, at the basal ganglia, the density of GFAP-positive astrocytes in the perivascular tissue had a significant positive correlation with the proportional thickness of the adventitia, which is an index of arteriosclerosis, and a significant negative correlation with the size of the perivascular space. The results suggested that the spotty regions in the brain MRI of elderly people do not represent dilatations of the perivascular space, but is mild brain damage caused by arteriosclerosis. (author)

    Full Text Available Autism Spectrum Disorder (ASD is a group of neurodevelopmental disorders with complex genetic etiology. Recent studies have indicated that children with ASD may have altered folate or methionine metabolism, suggesting that the folate–methionine cycle may play a key role in the etiology of ASD. SLC19A1, also referred to as reduced folate carrier 1 (RFC1, is a member of the solute carrier group of transporters and is one of the key enzymes in the folate metabolism pathway. Findings from multiple genomic screens suggest the presence of an autism susceptibility locus on chromosome 21q22.3, which includes SLC19A1. Therefore, we performed a case-control study in a Japanese population. In this study, DNA samples obtained from 147 ASD patients at the Kanazawa University Hospital in Japan and 150 unrelated healthy Japanese volunteers were examined by the sequence-specific primer-polymerase chain reaction method pooled with fluorescence correlation spectroscopy. p < 0.05 was considered to represent a statistically significant outcome. Of 13 single nucleotide polymorphisms (SNPs examined, a significant p-value was obtained for AA genotype of one SNP (rs1023159, OR = 0.39, 95% CI = 0.16–0.91, p = 0.0394; Fisher’s exact test. Despite some conflicting results, our findings supported a role for the polymorphism rs1023159 of the SLC19A1 gene, alone or in combination, as a risk factor for ASD. However, the findings were not consistent after multiple testing corrections. In conclusion, although our results supported a role of the SLC19A1 gene in the etiology of ASD, it was not a significant risk factor for the ASD samples analyzed in this study.

    Full Text Available The influence of the non-proportional loadings on the fatigue life depends on the material ductility. Ductile materials react with a shortening of lifetime compared to proportional loading conditions. For a semiductile material there is almost no difference between proportional and non-proportional loadings with respect to the fatigue life. Brittle materials show an increase of the lifetime under non-proportional loadings. If fatigue life assessment is performed using stress-based hypotheses, it is a rather difficult task to take into account material ductility correctly, especially the fatigue life reduction as displayed by ductile materials. Most stress-based hypotheses will compute a longer fatigue life under non-proportional loading conditions. There are also hypotheses, which already include quantitative evaluation of the non-proportionality (e.g. EESH, SSCH and MWCM. Anyway in order to improve assessment for ductile materials, some sort of numerical measure for the degree of non-proportionality of the fatigue loading is required. A number of measures of this kind (or non-proportionality factors were proposed in the literature and are discussed here: - the factor used in EESH is a quotient of stress amplitudes integrals, - the factor according to Gaier, which works with a discrete stress tensor values in a scaled stress space, - the factor according to Kanazawa, which makes use of plane-based stress values, - the factor used in MWCM, which exploits stress values in the plane with the highest shear stress amplitude, a new non-proportionality factor, which is based on the correlation between individual stress tensor components, is proposed. General requirements imposed on the non-proportionality factors are discussed and each of the factors is evaluated with respect to these requirements. Also application with the stress-based hypotheses is discussed and illustrated using the experimental data for aluminum and magnesium welded joints under

    The incidence of the external and middle ear squamous cell carcinoma (SCC) is extremely rare in the head and neck cancer with less than 1%. Therefore, the correlation between the staging classification and the prognosis has not been clear. Prognostic factors for patients with the external and middle ear SCC were assessed in the initial clinical symptoms and radiographic imaging. 13 patients with the external and middle ear SCC (5 male and 8 female) that had been treated at the Department of Otorhinolaryngology, Kanazawa University hospital from 2000 to 2006 were selected for this study. The radiation therapy followed surgery in ten patients. One patient received the radical cure irradiation before surgery. Two patients received a surgical excision alone. The temporal bone involvement and the parotid gland involvement in the radiographic image (computed tomography imaging and/or magnetic resonance imaging) were assessed. Clinical symptoms (otalgia, hearing disturbance, tinnitus, vertigo and facial nerve palsy) before treatment were reviewed based on the medical record. The correlation of those clinical factors and T staging in the Pittsburgh classification with overall survival was statistically assessed. The temporal bone involvement significantly correlated with worse prognosis. However, parotid gland involvement did not influence the prognosis. Moreover, statistically significant difference in T staging of the Pittsburgh classification (T1·T2 vs. T3·T4) was not found. The temporal bone involvement in the radiographic image was a prognostic factor for patients with the external and middle ear SCC. Pittsburgh classification needs to be modified because the bony part of the external auditory canal involvement is considered as T2 stage and the soft tissue involvement is defined as T4 stage.

  19. Art as an indicator of male fitness: does prenatal testosterone influence artistic ability?

    In his groundbreaking research, Geoffrey Miller (1999) suggests that artistic and creative displays are male-predominant behaviors and can be considered to be the result of an evolutionary advantage. The outcomes of several surveys conducted on jazz and rock musicians, contemporary painters, English writers (Miller, 1999), and scientists (Kanazawa, 2000) seem to be consistent with the Millerian hypothesis, showing a predominance of men carrying out these activities, with an output peak corresponding to the most fertile male period and a progressive decline in late maturity. One way to evaluate the sex-related hypothesis of artistic and cultural displays, considered as sexual indicators of male fitness, is to focus on sexually dimorphic traits. One of them, within our species, is the 2nd to 4th digit length (2D:4D), which is a marker for prenatal testosterone levels. This study combines the Millerian theories on sexual dimorphism in cultural displays with the digit ratio, using it as an indicator of androgen exposure in utero. If androgenic levels are positively correlated with artistic exhibition, both female and male artists should show low 2D:4D ratios. In this experiment we tested the association between 2D:4D and artistic ability by comparing the digit ratios of 50 artists (25 men and 25 women) to the digit ratios of 50 non-artists (25 men and 25 women). Both male and female artists had significantly lower 2D:4D ratios (indicating high testosterone) than male and female controls. These results support the hypothesis that art may represent a sexually selected, typically masculine behavior that advertises the carrier's good genes within a courtship context.

    The currently available Japanese normal database (NDB) in stress myocardial perfusion scintigraphy recommended by the Japanese Society of Nuclear Medicine (JSNM-NDB) is created based on the data from exercise tests. The newly developed adenosine normal database (ADS-NDB) remains to be validated for patients undergoing adenosine stress test. We tested whether the diagnostic accuracy of adenosine stress test is improved by the use of ADS-NDB (Kanazawa University). Of 233 consecutive patients undergoing (99m)Tc-MIBI adenosine stress test, 112 patients were tested. The stress/rest myocardial (99m)Tc-MIBI single-photon emission computed tomography (SPECT) images were analyzed by AutoQUANT 7.2 with both ADS-NDB and JSNM-NDB. The summed stress score (SSS) and summed difference score (SDS) were calculated. The agreements of the post-stress defect severity between ADS-NDB and JSNM-NDB were assessed using a weighted kappa statistic. In all patients, mean SSSs of all, right coronary artery (RCA), left anterior descending (LAD), and left circumflex (LCx) territories were significantly lower with ADS-NDB than those with JSNM-NDB. Mean SDSs in all, RCA, and LAD territories were significantly lower with ADS-NDB than those with JSNM-NDB. In 28 patients with significant coronary stenosis, the mean SSS in the RCA territory was significantly lower with ADS-NDB than that with JSNM-NDB. In 84 patients without ischemia, both mean SSSs and SDSs in all, RCA, LAD, and LCx territories were significantly lower with ADS-NDB than those with JSNM-NDB. Weighted kappa values of all patients, patients with significant stenosis, and patients without ischemia were 0.89, 0.83, and 0.92, respectively. Differences were observed between results from ADS-NDB and JSNM-NDB. The diagnostic accuracy of adenosine stress myocardial perfusion scintigraphy may be improved by reducing false-positive results.

    Quartz crystal impedance analysis has been developed as a technique to assess whether room-temperature ionic liquids are Newtonian fluids and as a small-volume method for determining the values of their viscosity-density product, rho eta. Changes in the impedance spectrum of a 5-MHz fundamental frequency quartz crystal induced by a water-miscible room-temperature ionic liquid, 1-butyl-3-methylimiclazolium trifluoromethylsulfonate ([C4mim][OTf]), were measured. From coupled frequency shift and bandwidth changes as the concentration was varied from 0 to 100% ionic liquid, it was determined that this liquid provided a Newtonian response. A second water-immiscible ionic liquid, 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide [C4mim][NTf2], with concentration varied using methanol, was tested and also found to provide a Newtonian response. In both cases, the values of the square root of the viscosity-density product deduced from the small-volume quartz crystal technique were consistent with those measured using a viscometer and density meter. The third harmonic of the crystal was found to provide the closest agreement between the two measurement methods; the pure ionic liquids had the largest difference of approximately 10%. In addition, 18 pure ionic liquids were tested, and for 11 of these, good-quality frequency shift and bandwidth data were obtained; these 12 all had a Newtonian response. The frequency shift of the third harmonic was found to vary linearly with square root of viscosity-density product of the pure ionic liquids up to a value of square root(rho eta) approximately 18 kg m(-2) s(-1/2), but with a slope 10% smaller than that predicted by the Kanazawa and Gordon equation. It is envisaged that the quartz crystal technique could be used in a high-throughput microfluidic system for characterizing ionic liquids.

    Full Text Available Introduction Lamprophyres are mesocratic to melanocratic igneous rocks, usually hypabyssal, with a panidiomorphic texture and abundant mafic phenocrysts of dark mica or amphibole (or both with or without pyroxene, with or without olivine, set in a matrix of the same minerals, and with alkali-feldspar restricted to the groundmass (Woolley et al., 1996. Lamprophyres are frequently associated with orogenic settings and a mantle modified by dehydration of subducted slab (Gibson et al., 1995. Small outcrops of lamprophyres with Paleozoic to Oligocene age are reported from the central parts of Iran (Torabi 2009 and 2010. The primary magmas of these lamprophyres were derived from decompression melting of the mantle induced by a tensional regime of continental crust (Torabi, 2010. Bayat and Torabi (2011 called the western part of the CEIM (Central-East Iranian Microcontinent (Anarak to Bayazeh a “Paleozoic lamprophyric province” and suggested that the lamprophyre magmas were formed by subduction of Paleo-Tethys oceanic crust from the Early to late Paleozoic which resulted in the mantle metasomatism and enrichment. Lamprophyric dykes and stocks of the Kal-e-kafi area (Central Iran, Northern part of Yazd Block cross-cut the Eocene volcanic rocks and other older rock units such as Cretaceous limestone. These lamprophyres are mainly composed of hornblende (magnesio-hastingsite, clinopyroxene (diopside and plagioclase (labradorite to bytownite as phenocryst, in a matrix of fine to medium grained of the same minerals and orthoclase, apatite, magnetite, chlorite and epidote. In this paper that is a report on the first study on the calc-alkaline lamprophyres of Central Iran, the petrography and mineral chemistry of calc-alkaline lamprophyric dykes of the Kal-e-kafi area are discussed. Materials and methods Chemical composition of minerals were conducted at Kanazawa University (Kanazawa, Japan using the wavelength-dispersive electron probe microanalyzer

The Micro-Raman spectroscopy (a HORIBA Jobin Yvon, LabRAM HR800 system equipped with a 532 nm Nd:YAG laser of Showa Optronics co., Ltd, J100GS-16, and an optical microscope of Olympus, BX41, Kanazawa University were used in determination of serpentine minerals. Results The lherzolite is primarily composed olivine, orthopyroxene, clinopyroxene and Cr-spinel, but secondary hydrous and non-hydrous Mg-silicate minerals have been formed during the further serpentinization and metamorphism. Lherzolite is including of olivine (~70 Vol%, forsterite-rich, orthopyroxene (~15-20 Vol%, enstatite – bronzite, clinopyroxene (5-7 Vol%, diopside - augite, and vermicular brown Cr-spinel (60-70 Vol%, chrysolite, orthopyroxene (~30 Vol%, bronzite, a small amount of clinopyroxene, and subhedral dark brown Cr-spinel, talc, tremolite, magnetite, and chlorite. Dunites are composed exclusively of olivine, minor amounts of subhedral, dark brown Cr-spinel, serpentine, metamorphic tremolite, talc and chlorite. The rocks show secondary textures of mesh, poikiloblastic, nematoblastic and jack-straw textures, but original granublastic and porphyroclastic textures are well preserved. Pyroxenes show kink bands, warped cleavages, and undulatory extinction related to metamorphic condition of upper mantle. Petrographical features indicate that a metamorphism at amphibolite facies occurred after serpentinization and chloritization of the Darreh Deh peridotites. Chrysotile cut the primary phases of olivine and pyroxene, but not the metamorphic phases of olivine neoblasts, tremolite, talc and chlorite. Some chlorite crosscut the serpentine veins, and some are in the rim of Cr-spinel and clinopyroxenes. They are mostly replaced by tremolite. Metamorphic olivines have recrystallized as fine-grained neoblasts with lower CaO content (in comparison with the primary and replacive olivines, because they have been formed at the

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

    Surface seawater samples were collected along the track of the R/V Hakuho-Maru cruise (KH-96-5) from Tokyo to the Southern Ocean. The 137 Cs activities were determined for the surface waters in the western North Pacific Ocean, the Sulu and Indonesian Seas, the eastern Indian Ocean, the Bay of Bengal, the Andaman Sea, and the South China Sea. The 137 Cs activities showed a wide variation with values ranging from 1.1 Bq m -3 in the Antarctic Circumpolar Region of the Southern Ocean to 3 Bq m -3 in the western North Pacific Ocean and the South China Sea. The latitudinal distributions of 137 Cs activity were not reflective of that of the integrated deposition density of atmospheric global fallout. The removal rates of 137 Cs from the surface waters were roughly estimated from the two data sets of Miyake et al. [Miyake Y, Saruhashi K, Sugimura Y, Kanazawa T, Hirose K. Contents of 137 Cs, plutonium and americium isotopes in the Southern Ocean waters. Pap Meteorol Geophys 1988;39:95-113] and this study to be 0.016 yr -1 in the Sulu and Indonesian Seas, 0.033 yr -1 in the Bay of Bengal and Andaman Sea, and 0.029 yr -1 in the South China Sea. These values were much lower than that in the coastal surface water of the western Northwest Pacific Ocean. This was likely due to less horizontal and vertical mixing of water masses and less scavenging. 239+24 Pu activities and 24 Pu/ 239 Pu atom ratios were also determined for the surface waters in the western North Pacific Ocean, the Sulu and Indonesian Seas and the South China Sea. The 24 Pu / 239 Pu atom ratios ranged from 0.199 ± 0.026 to 0.248 ± 0.027 on average, and were significantly higher than the global stratospheric fallout ratio of 0.18. The contributions of the North Pacific Proving Grounds close-in fallout Pu were estimated to be 20% for the western North Pacific Ocean, 39% for the Sulu and Indonesian Seas and 42% for the South China Sea by using the two end-member mixing model.

    In order to better characterize ice nucleating (IN) aerosol particles in the atmosphere, we investigated the chemical composition, mixing state, and morphology of atmospheric aerosols that nucleate ice under conditions relevant for mixed-phase clouds. Five standard mineral dust samples (quartz, K-feldspar, Na-feldspar, Arizona test dust, and Asian dust source particles) were compared with actual aerosol particles collected from the west coast of Japan (the city of Kanazawa) during Asian dust events in February and April 2016. Following droplet activation by particles deposited on a hydrophobic Si (silicon) wafer substrate under supersaturated air, individual IN particles were located using an optical microscope by gradually cooling the temperature to -30 °C. For the aerosol samples, both the IN active particles and non-active particles were analyzed individually by atomic force microscopy (AFM), micro-Raman spectroscopy, and scanning electron microscopy (SEM) coupled with energy dispersive X-ray spectroscopy (EDX). Heterogeneous ice nucleation in all standard mineral dust samples tested in this study was observed at consistently higher temperatures (e.g., -22.2 to -24.2 °C with K-feldspar) than the homogeneous freezing temperature (-36.5 °C). Meanwhile, most of the IN active atmospheric particles formed ice below -28 °C, i.e., at lower temperatures than the standard mineral dust samples of pure components. The most abundant IN active particles above -30 °C were predominantly irregular solid particles that showed clay mineral characteristics (or mixtures of several mineral components). Other than clay, Ca-rich particles internally mixed with other components, such as sulfate, were also regarded as IN active particle types. Moreover, sea salt particles were predominantly found in the non-active fraction, and internal mixing with sea salt clearly acted as a significant inhibiting agent for the ice nucleation activity of mineral dust particles. Also, relatively

These symptoms include excessive acquisition, difficulty in discarding, and excessive clutter that causes distress. We conducted three studies to examine the factor structure, reliability, and validity of the Japanese version of the HRS-SR (HRS-SR-J. Methods: Study 1 examined its reliability; 193 college students and 320 adolescents and adults completed the HRS-SR-J and, of the college students, 32 took it again 2 weeks later. Study 2 aimed to confirm that its scores in a sample of 210 adolescents and adults are independent of social desirability. Study 3 aimed to validate the HRS-SR-J in the aspects of convergent and discriminant validity in a sample of 550 adults. Results: The HRS-SR-J showed good internal consistency and 2-week test–retest reliability. Based on the nonsignificant correlations between the HRS-SR-J and social desirability, the HRS-SR-J was not strongly affected by social desirability. In addition, it also had a good convergent validity with the Japanese version of the Saving Inventory-Revised (SI-R-J and the hoarding subscale of the Obsessive-Compulsive Inventory, while having a significantly weaker correlation with the five subscales of the Obsessive-Compulsive Inventory, except for the hoarding subscale.

    Full Text Available Interactions between minerals and microorganisms play a crucial role in living wood tissues. However, living wood tissues have never been studied in the field. Fortunately, we found several kurogaki (black persimmon; Diospyros kaki trees at Tawara in Kanazawa, Ishikawa, Japan. Here, we report the characterization of kurogaki based on scanning electron microscopy equipped with energy-dispersive spectroscopy (SEM-EDS and transmission electron microscopy (TEM, associated with inductively coupled plasma-mass spectrometry (ICP-MS analyses, X-ray fluorescence analyses (XRF and X-ray powder diffraction (XRD analyses. This study aims to illustrate the ability of various microorganisms associated with biominerals within wood tissues of kurogaki, as shown by SEM-EDS elemental content maps and TEM images. Kurogaki grows very slowly and has extremely hard wood, known for its striking black and beige coloration, referred to as a “peacock pattern”. However, the scientific data for kurogaki are very limited. The black “peacock pattern” of the wood mainly comprises cellulose and high levels of crystal cristobalite. As per the XRD results, the black taproot contains mineralized 7 Å clays (kaolinite, cellulose, apatite and cristobalite associated with many microorganisms. The chemical compositions of the black and beige portions of the black persimmon tree were obtained by ICP-MS analyses. Particular elements such as abundant Ca, Mg, K, P, Mn, Ba, S, Cl, Fe, Na, and Al were concentrated in the black region, associated with Pb and Sr elements. SEM-EDS semi-qualitative analyses of kurogaki indicated an abundance of P and Ca in microorganisms in the black region, associated with Pb, Sr, S, Mn, and Mg elements. On the other hand, XRF and XRD mineralogical data showed that fresh andesite, weathered andesite, and the soils around the roots of kurogaki correlate with biomineralization of the black region in kurogaki roots, showing clay minerals (kaolinite and

    In previous editorials I have written about the absent-minded and socially-inept 'nutty professor' stereotype in science, and the phenomenon of 'psychological neoteny' whereby intelligent modern people (including scientists) decline to grow-up and instead remain in a state of perpetual novelty-seeking adolescence. These can be seen as specific examples of the general phenomenon of 'clever sillies' whereby intelligent people with high levels of technical ability are seen (by the majority of the rest of the population) as having foolish ideas and behaviours outside the realm of their professional expertise. In short, it has often been observed that high IQ types are lacking in 'common sense'--and especially when it comes to dealing with other human beings. General intelligence is not just a cognitive ability; it is also a cognitive disposition. So, the greater cognitive abilities of higher IQ tend also to be accompanied by a distinctive high IQ personality type including the trait of 'Openness to experience', 'enlightened' or progressive left-wing political values, and atheism. Drawing on the ideas of Kanazawa, my suggested explanation for this association between intelligence and personality is that an increasing relative level of IQ brings with it a tendency differentially to over-use general intelligence in problem-solving, and to over-ride those instinctive and spontaneous forms of evolved behaviour which could be termed common sense. Preferential use of abstract analysis is often useful when dealing with the many evolutionary novelties to be found in modernizing societies; but is not usually useful for dealing with social and psychological problems for which humans have evolved 'domain-specific' adaptive behaviours. And since evolved common sense usually produces the right answers in the social domain; this implies that, when it comes to solving social problems, the most intelligent people are more likely than those of average intelligence to have novel but

Three types of MWCNTs – VGCF®-X, VGCF®-S, and VGCF® (vapor grown carbon fibers; with diameters of 15, 80, and 150 nm, respectively – and three CSCNTs of different lengths (CS-L, 20–80 µm; CS-S, 0.5–20 µm; and CS-M, of intermediate length were tested. Human bronchial epithelial (BEAS-2B and malignant pleural mesothelioma cells were exposed to the CNTs (1–50 µg/mL, and cell viability, permeability, uptake, total reactive oxygen species/superoxide production, and intracellular acidity were measured. CSCNTs were less toxic than MWCNTs in both cell types over a 24-hour exposure period. The cytotoxicity of endocytosed MWCNTs varied according to cell type/size, while that of CSCNTs depended on tube length irrespective of cell type. CNT diameter and length influenced cell aggregation and injury extent. Intracellular acidity increased independently of lysosomal activity along with the number of vacuoles in BEAS-2B cells exposed for 24 hours to either CNT

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. We aimed to evaluate the effectiveness of coinfusion of dexamethasone and oxaliplatin to prevent oxaliplatin-induced hypersensitivity reactions.Patients and methods: The AVOID trial was a prospective, multicenter, open-label, single-arm Phase II trial conducted from January to September 2013. The study included 73 patients who received capecitabine plus oxaliplatin (XELOX or XELOX plus bevacizumab therapy for colorectal cancer.

The strain M0880/a is most closely related to Japanese isolates (Kanazawa-1, -2, and Kaga, whereas FK01 groups closely with a Kawaguchi isolate. Conclusion Our results indicate that Paulinella chromatophora comprises at least two distinct evolutionary lineages and likely encompasses a broader taxonomic diversity than previously thought. The finding of a single plastid origin for both lineages shows these taxa to be valuable models for studying post-endosymbiotic cell and genome evolution.

However, few have administered surveys to social welfare professionals at home care. Thus, this study aimed to investigate the current level of knowledge and practice regarding pressure injury prevention among Japanese care managers. Patients and methods: A cross-sectional study among care managers working in a Japanese city was performed from June to July 2016. Data were collected using a questionnaire to assess the participants’ knowledge of and practice for pressure injury prevention. The questionnaire included 1 measures of demographic characterization, 2 measures of knowledge, 3 measures of practice, and 4 measures of the difficulties of using pressure injury risk assessment scales. Results: A total of 48 participants were analyzed (response rate: 55%. The overall knowledge and practice scores were 78.6% and 61.8%, respectively. The percentages of participants who knew the risk assessment scales were 38%, 26%, and 13% for the Braden scale, the Ohura–Hotta scale, and the University of Kanazawa scale, respectively. We also observed that 50% of the participants in this study believed that the use of risk assessment scales in daily practice in home care may be difficult. Conclusion: Through the results of this questionnaire survey, we concluded that the current levels of knowledge and practice regarding pressure injury prevention among the care managers participating in our study were “moderate” and “low”, respectively. Low scores were obtained for knowledge with respect to the question, “Using risk assessment scales”. We will develop a

The area under the drug concentration–time curve (AUC/minimum inhibitory concentration (MIC was identified as a pharmacokinetic–pharmacodynamic (PK–PD parameter of glycopeptide antibiotics that correlated with bacteriological responses and clinical outcomes. Although optimized dosing regimens based on PK–PD are needed, a PK–PD analysis of teicoplanin against methicillin-resistant Staphylococcus aureus (MRSA infections has not yet been performed. Thus, this study examined patients with MRSA infections, who were administered with teicoplanin in order to determine the target AUC/MIC ratio. Methods: This study retrospectively assessed data obtained as part of our routine therapeutic drug monitoring (TDM of teicoplanin therapy in 46 patients with MRSA infections at Kagoshima University Hospital. Serum concentrations of teicoplanin were determined using a fluorescence polarization immunoassay system and used for a Bayesian PK estimation to estimate AUC for 24 hours (AUC24. The MIC value for teicoplanin was determined using a standardized agar dilution method. The effects of teicoplanin were evaluated in terms of bacteriological responses by a quantitative assessment.

    In this paper, the author attempts to generalize the evolution of pharmaceutical schools in Toyama since the Meiji Era. The copy of a petition drafted by pill peddlers of Toyama in 1873 suggests that there were expectations that a "Semi (chemicals)" school was going to be established; however, this was not realized. In 1877, the Ishikawa Prefectural Government established a small-scale pharmaceutical school associated with the public hospitals of Kanazawa, Toyama and Kukui. In 1883, Toyama Prefecture became isolated from Ishikawa Prefecture, and the above-mentioned pharmaceutical school continued operations until 1887, when the government closed it due to financial problems. Persuaded through a lecture given by Dr. Keizo Tampa, a professor of Tokyo University, volunteers in Toyama Prefecture established an independent pharmaceutical school in 1894. However, student enrollment was too low to maintain operation, and the administration started planning to relocate the school to the city of Toyama. This was realized in 1897. In 1900, a massive fire burnt down much of the city, severely damaging the school building and much of the equipment inside. Restoration would be costly. As a solution to the problem, the administration of the school was transferred from Toyama City to Toyama Prefecture. With money from the prefecture, the school facilities were repaired and teaching staff recruited. In 1909, the school ranking was promoted to college status, and it became one of the first academic institutions to issue a pharmacist licence to graduates without requiring them to take the national examination (i.e., with the exception of medical colleges). Subsequently, in 1920, the administration of the college was transferred from the Toyama Prefectural Government to Japan's Central Government, at which time the facilities were improved and a wider range of education subjects were introduced.The college was again relocated to the city suburbs, where the facilities included the

    Chushiro Hayashi, the greatest Japanese theoretical astrophysicist, died of old age at a hospital in Kyoto on 28 February, 2010; he was 89 years old. C. Hayashi was born in Kyoto on July 25, 1920 as the fourth son of his parents Mume and Seijiro Hayashi. His father Seijiro managed a small finance company and the family "Hayashi" can trace its history back to honorable master carpenters who engaged in construction of the historic Kamigamo-shrine and Daitokuji-temple in Kyoto. In his high-school days in Kyoto, Hayashi enjoyed judo, and he was interested in philosophy and read a lot of philosophy books. Some of his schoolmates thought that Hayashi would become a philosopher. After graduating high school, he moved to Tokyo and entered the University of Tokyo, Department of physics in 1940, where he encountered astrophysics through a paper by G. Gamow and M. Schönberg on the URCA process (1941), A.S. Eddington's book "Internal Constitution of the Stars" (1926), etc. It was a difficult time of World War II. After a short time at university of two and half years, he graduated and was conscripted into the Navy. In 1945 the war was over he returned to his hometown Kyoto, where he joined a group of Professor Hideki Yukawa at Kyoto University, and studied elementary particle physics as well as astrophysics. In his early outstanding paper (1950), Hayashi pointed out an important effect of neutrinos in the expanding early hot universe, resulting in chemical equilibrium between neutrons and protons, while Gamow et al. (1948) did not notice the effect in their abg-theory, where they assumed a pure neutron state as an initial state. Also Hayashi investigated the structures of red giant stars; he showed how red giant stars kept such large radius structures, in terms of stellar models with energy source of nuclear shell-burning (1949, 1957). He received a DSc in 1954; the title of his thesis was "Hamiltonian Formalism in Non-local Field Theories." After that, Hayashi concentrated

    The Penin. Shimokita as a Nuclear Peninsula: Past and Present: Since 1967, the Penin. Shimokita is characterized as a Nuclear Peninsula. Then the Shimokita Wharf of Ohminato Port in Mutsu-city was appointed as a home port of the Nuclear Power Ship Mutsu. In 1984 Mutsu Ogawara Region, a southern part of the Penin. around Rokkasho, was paid attention as a target region for reprocessing facilities of burnt nuclear fuels from all the nuclear power stations in this country. At the present stage, uranium enrichment facilities, low-level radioactive waste laying center and high-level vitrified waste storage center are in operation, and the reprocessing facilities are under construction. Burnt fuels are also carried into the site before completion of the facilities mainly for the purpose of cooling in the water pool, because cooling pools of some nuclear power stations are already full of the burnt nuclear fuels. Recently, Mayor of Mutsu has announced that Mutsu City are ready to accept a 'temporary' storage facilities for burnt nuclear fuels. Constructions of two nuclear power stations are in procession. Practice and Results: After the JCO critical accident, members of the Penin. Shimokita Activation Society (SAS) have made voluntarily some chances for learning neutron, which has played a definite role in the accident. Before the time of the accident, they have ever heard nothing about a neutron. So, neutron is entirely a new face radiation for them. Members of NPO EGG (Environmental Guardian of GALA) then obtained information from Urgent Session of the 44th Annual Meeting of Radiochemistry held in Tsukuba by the Japan Society of Nuclear and Radiochemical Sciences, and attended the seminar on the JCO accident held at Institute for Environmental Sciences (IES) in Rokkasho. A title of the seminar was 'Extremely Low Background Gamma Ray Spectroscopy applied to the JCO Accident'. The lecturer was Prof. Komura of LLRL (Low Level Radioactivity Laboratory), Kanazawa University

    detector at the Kanazawa University. The {sup 134}Cs/{sup 137}Cs activity ratio of all samples was nearly 1.0 within measurement error after the decay correction to March 11 in 2011. Therefore, a major part of radiocesium is derived from the Fukushima Dai-ichi NPP accident. The {sup 137}Cs radioactivity ranges from 0.014 Bq/L to 0.103 Bq/L and shows maximum value at the lower middle site in the Abukuma River. The {sup 137}Cs radioactivity ranges from 0.004 Bq/L to 0.254 Bq/L for river water samples from the six rivers (Uta, Niida, Ntsui, Kuji and Naka Rivers) flowing to Pacific Ocean. Tone River systems have 0.008-0.016 Bq/L at the upper site and 0.028 Bq/L at the lower site. The Niida River indicates the highest value because it is running through the upper higher contaminated area. The upper Tone River systems resemble {sup 137}Cs radioactivity of the Natsui, Kuji and Naka Rivers. However, the {sup 137}Cs radioactivity in the lower Tone River is almost similar with that of the upper and middle of Abukuma River, and Natsui River. Their horizontal distributions were consistent with those of material that had been deposited on the ground surface, though the research was carried out 18 months after the accident. (authors)

    NPO Foundation Informing and Region Creating Group for Resource Recycling-type Society (EGG=Environmental Guardian of Gaia) authorized by Aomori Prefecture in September 2000 has performed a fixed site measurement of environmental neutrons under instruction of Prof. Kazuhisa Komura, Low Level Radioactivity Laboratory (LLRL), Faculty of Science, Kanazawa University since 2001. With a strong conviction that a level of a region does not go beyond a level of intelligence of residents of the region, the NPO EGG reports results of the measurements of environmental neutrons in the Peninsula Shimokita to pupils of junior high school who bear the future of Aomori Prefecture. It is one of our activities for elevating safety we create to relief. The measurements are not a daily monitoring for us at present, but correspond to the well known long-term measurements over several ten years of carbon dioxide in the air at Hawaii by Dr. Keeling, which are made for our children and grandchildren. The EGG has organized Gaia Aomori Energy Forum 2002 (keynote address: Hiranuma Minister of Economy and Industry) at Rokkasho Village and Mutsu City in Peninsula Shimokita, Gaia Aomori Energy Forum 2003 (keynote address: Hiranuma Minister of Economy and Industry) at Rokkasho Village and Mutsu City in Penin. Shimokita. The result of measurements was regarded to reasonably constant in the range of error in measurement. The numerical values are comparable to the results of measurement in Tatsunokuchi. The measurements were made in similar way in 2003 as well as in 2002. The results of measurements was regarded to reasonably constant in the range of error in measurement. The numerical values are comparable to the results of measurement in Tatsunokuchi. The EGG has thought that development of new energies should be proceeded with in addition to the practical use of the nuclear energy for preservation of the global environment. In order to prevent a mishandling in the processing in the nuclear

    , banded meta-chert, and succession of schist and marble (Davoudzadeh, 1972; Jabbari, 1997; Pirnia Naeini, 2006; Torabi, 2012; Shirdashtzadeh, 2006. In this ophiolite, the leucogabbro intrusions crosscut all other rock units. Materials and Methods Mineralogical analyses were conducted by wavelength-dispersive EPMA (JEOL JXA-8800R at the Cooperative Centre of Kanazawa University (Japan. The analyses were performed under an accelerating voltage of 15 kV and a beam current of 15 nA. JEOL software using ZAF corrections was employed for data reduction. Natural and synthetic minerals of known composition are used as standards. The Fe3+ content in minerals was estimated by assuming mineral stoichiometry. Results In the contact zone of leucogabbros and mantle peridotites of the Naein ophiolite, wehrlite and olivine clinopyroxenite are formed. Rock-forming minerals of these wehrlites are olivine (chrysolite, clinopyroxene (diopside, Cr-spinel, serpentine, amphibole (tremolite and tremolitic hornblende, epidote and magnetite. Comparison of mineral chemistry of olivine, clinopyroxene and chromian spinel in wehrlites and mantle peridotites indicate that chemical composition of clinopyroxene and olivine in these rocks are different, but chemistry of Cr-spinels in harzburgite and wehrlite are nearly same. Discussion According to the resistance of Cr-spinel against the metamorphism and alteration, it can be concluded that the wehrlites in contact zone of gabbros and mantle peridotites are formed at the expense of harzburgite. Olivine and clinopyroxene of wehrlites are formed by serpentine metamorphism and interaction of serpentine and calcium of gabbro, respectively. Field study of the research area shows that the leucogabbro intrudes the harzburgite. This research shows that after the serpentinization of mantle harzburgite, the gabbro intrusions crosscut the serpentinized peridotites, and wehrlite and olivine clinopyroxenite formed in the contact zone.

    , Toshio Ando from the University of Kanazawa provides an overview of developments that have allowed atomic force microscopy to move from rates of the order of one frame a minute to over a thousand frames per second in constant height mode, as reported by Mervyn Miles and colleagues at Bristol University and University College London [8]. Among the pioneers in the field, Ando's group demonstrated the ability to record the Brownian motion of myosin V molecules on mica with image capture rates of 100 x 100 pixels in 80 ms over a decade ago [9]. The developments unleash the potential of atomic force microscopy to observe the dynamics of biological and materials systems. If seeing is believing, the ability to present real motion pictures of the nanoworld cannot fail to capture the public imagination and stimulate burgeoning new avenues of scientific endeavour. Nearly 350 years on from the publication Micrographia, images in microscopy have moved from the page to the movies. References [1] Binnig G, Quate C F, and Gerber Ch 1986 Phys. Rev.

    Full Text Available Introduction The study area is located in the Shurab area that is about 50 Km Southeast of Qom. Volcanic rocks of the Shurab area have basaltic composition that is associated with salt and marl units. Igneous rocks of the Shurab area have not been comprehensively studied thus far. Clinopyroxene composition of volcanic rocks, and especially the phenocrysts show Magma chemistry and can help to identify magma series (Lebas, 1962; Verhooge, 1962; Kushiro, 1960, Leterrier et al., 1982, tectonic setting (Leterrier et al., 1982; Nisbet and Pearce, 1977 as well as temperature formation and pressure of rock formation. Some geologists have estimated temperature of clinopyroxene formation by clinopyroxene composition (Adams and Bishop, 1986 and clinopyroxene-olivine couple. So, clinopyroxene is used in this study in order to identify magma series, tectonic setting, plus the temperature and pressure of volcanic rocks of the Shurab. Material and method Clinopyroxene analyses were conducted by wavelength-dispersive EPMA (JEOL JXA-8800R at the Cooperative Centre of Kanazawa University (Japan. The analyses were performed under an accelerating voltage of 15 kV and a beam current of 20 nA. The ZAF program was used for data corrections. Natural and synthetic minerals of known composition were used as standards. The Fe3+ content in minerals was estimated by Droop method (Droop, 1987. Discussion In the Shurab area, the volcanic rocks area with basaltic composition are located 50 km Southeast of Qom. Their age is the early Oligocene and they are associated with the salty marl units of the Lower Red Formation (LRF. The hand specimens of the studied rocks look green. These rocks are intergranular, microlitic, porphyric, vitrophyric and amygdaloidal and they consist of olivine, pyroxene and plagioclase. Accessory minerals contain sphene, apatite and opaque. According to Wo-En-Fs diagram (Morimoto, 1988, clinopyroxenes indicate diopside composition. Clinopyroxenes are

    Turkmeni blueschists. Material and methods This study is based on field observations and petrographical and analytical studies. Satellite images and a geological map were prepared. About 20 thin sections were supplied for petrological studies. Mineral chemical analyses were carried out by a JEOL JXA-8800R electron probe micro-analyzer (EPMA at the Cooperative Center of Kanazawa University, Japan. The analyses were performed under an accelerating voltage of 15 kV and a beam current of 15 nA with 3µm probe beam diameter. The Fe3+ contents of minerals were estimated by assuming ideal mineral stoichiometry. The representative mineral compositions are given in Tables 1-3. Major oxides, rare earth elements (REE and trace elements of five blueschists samples were analyzed by the ICP-MS method (Kanpanzhouh Research Company, Tehran, Iran of the SGS laboratory of Canada. Whole rock chemical data are presented in Table 4. Results and discussion Petrographical and geochemical characteristics of Turkmeni blueschists reveal that they were derived from a similar mantle source and underwent analogous melt extraction and post magmatism occurrences. According to the trace and rare earth elements contents, the protolith of blueschists should be formed by crystallization of tholeiitic basalt and have sub-alkali basalt nature. Blueschists have LREE values more than HREE. High amounts and evident variations of LIL elements are obvious. Negative anomalies of HFSE such as Nb, Hf, Zr and Ti are evident in Turkmeni blueschist. REE trends of these rocks resemble as the back arc basin basalts. Based on the Nb/La ratio and REE contents, the original magma has been generated by low to medium degree of partial melting of a lithospheric mantle spinel lherzolite. Geochemical characteristics and normalized diagrams reveal that primary magma of protolith has been nature near to IAB and E-MORB. The related processes to subduction of Paleo-Tethys oceanic crust led to mantle enrichment and carbonate

    SAWADA (Services for Health in Asian & African Regions (SHARE)). In 2006, Tokyo Metropolitan Government started to dispatch interpreters for foreigners to strengthen DOTS program. Collaboration with NGOs made it possible to train 37 volunteer interpreters, and to provide services in 13 languages, as of 2010. In Japan, the treatment defaulter rate among non-Japanese tuberculosis patients had been remarkably high. But with having the assistance of interpreters, the treatment completion rate has become higher than 80%. It is recommended to expand a similar system to other part of Japan, as the proportion of foreigners among total tuberculosis cases keeps on increasing nationwide. 3. Tuberculosis problems in Japan from the view point of homelessness-through the activities of a NPO supporting the homeless in collaboration with a public health center: Sadako KANAZAWA (Volunteer, NPO Medical Care Team of Shinjuku Renraku-Kai). It has been 20 years since the issue of homelessness emerged in Japanese society. The people with a history of both tuberculosis and experience of homelessness tend to show a poor prognosis. Our team has played an active role, working with Shinjuku Public Health Center for conducting a screening for tuberculosis every year. It seems that the screening service itself does not make a fundamental solution for homeless people with tuberculosis. Developing a more basic system of 'from street to apartment' is more essential. We believe that understanding the importance of the system is most essential to the people who are involved in health and medical care. 4. What we have learned from DOTS--Toward care by cuddling the patient's mind: Kazuyo ARIMA (PHN, Osaka City Public Health Center). Osaka City has achieved the goals of DOTS set up by the City's TB Control Guidelines since 2001 such as 80% DOTS implementation rate, halving the defaulter rate and incidence rate. It was shown by analysis that the treatment success depends on 'patient's awareness of the
