    Bartonellae are emerging vector-borne pathogens infecting erythrocytes and endothelial cells of various domestic and wild mammals. Blood samples were collected from domestic and wild canids in Iraq under the United States Army zoonotic disease surveillance program. Serology was performed using an indirect immunofluorescent antibody test for B. henselae, B. clarridgeiae, B. vinsonii subsp. berkhoffii and B. bovis. Overall seroprevalence was 47.4% in dogs (n = 97), 40.4% in jackals (n = 57) and 12.8% in red foxes (n = 39). Bartonella species DNA was amplified from whole blood and representative strains were sequenced. DNA of a new Bartonella species similar to but distinct from B. bovis, was amplified from 37.1% of the dogs and 12.3% of the jackals. B. vinsonii subsp. berkhoffii was also amplified from one jackal and no Bartonella DNA was amplified from foxes. Adjusting for age, the odds of dogs being Bartonella PCR positive were 11.94 times higher than for wild canids (95% CI: 4.55-31.35), suggesting their role as reservoir for this new Bartonella species. This study reports on the prevalence of Bartonella species in domestic and wild canids of Iraq and provides the first detection of Bartonella in jackals. We propose Candidatus Bartonella merieuxii for this new Bartonella species. Most of the Bartonella species identified in sick dogs are also pathogenic for humans. Therefore, seroprevalence in Iraqi dog owners and bacteremia in Iraqi people with unexplained fever or culture negative endocarditis requires further investigation as well as in United States military personnel who were stationed in Iraq. Finally, it will also be essential to test any dog brought back from Iraq to the USA for presence of Bartonella bacteremia to prevent any accidental introduction of a new Bartonella species to the New World

    We have developed a 50kg class microsatellite HIBARI . The mission of this satellite is to demonstrate a novel attitude control method for microsatellites which is called “Variable Shape Attitude Control (VSAC).” VSAC is a method using anti-torque by driving variable shape structures. HIBARI has four drivable solar array paddles, and will demonstrate VSAC. The development of HIBARI began in 2019, and it was injected into orbit in November 2021 under the Innovative Satellite Technology Demonstration Program led by JAXA. Currently, HIBARI has completed its critical phase and paddle deployment phase, and is conducting paddle drive experiments in orbit. In paddle drive experiments, the paddles are driven according to the command values, and the accompanying attitude change is confirmed. These results indicate that the satellite can generate angular velocities of 4 deg/s or more and achieve the target agile maneuver of 30deg in 10seconds, which is comparable to that of CMG for microsatellite

    We are developing a 40kg class microsatellite “HIBARI”. The main technical mission is demonstration a novel attitude control method called “Variable Shape Attitude Control (VSAC)” proposed by Matunaga, Tokyo Institute of Technology. This VSAC is based on an idea to utilize a reaction torque generated by changing the shape of satellites, for example driving solar array paddles by actuators. HIBARI is planned to be launched in fiscal year 2021 under “Innovative Satellite Technology Demonstration Program” led by JAXA. We are developing EM of HIBARI and describes those in this paper. Specifically, the results of missions, systems, and various tests are shown and the validity is derived

    Japan’s aging population rate is increasing and healthy life expectancy has decreases by 10 years shorter than average life expectancy. The aim of this study is to determine the relationship among chronic disease, sleep quality, health-related quality of life (HRQOL), and activities of daily living in people over 55 years old who live in the community. Subjects were 161 persons aged 57 to 90 years who were treated with chronic disease in the outpatient department of the A hospital. Exclusion criteria included patients with dementia, cancer and severe heart disease. The survey evaluation questionnaires included the Pittsburgh Sleep Quality Index (PSQI), HRQOL by Short-Form 8 Health Survey (SF-8), and activities of daily living. Variables associated with quality of sleep, HRQOL in univariate analysis with p < 0.05 were entered into multivariate analysis using logistic regression with a stepwise forward selection procedure to determine independent variables and their association with major causes. The logistic regression analysis was done using SPSS software and the post-hoc power of the study was estimated using G*power. The level of significance was set at p < 0.05. The risk factor of poor sleep quality was because of history of cancer [odds ratio (OR): 3.53, 95% confidence interval (CI): 1.06 - 11.77], and insomnia (OR: 3.25, 95% CI: 1.55 - 6.79). The risk factors of poor physical HRQOL were motor disease (OR: 2.62, 95% CI: 1.36 - 5.07), respiratory disease (OR: 3.24, 95% CI: 1.27 - 8.26) and having pain (OR: 11.71, 95% CI: 5.35 - 25.66). In addition, anemia was found to be a risk factor of poor mental HRQOL (OR: 4.87, 95% CI: 1.11 - 21.33). The feeling-for-their-body-age (OR: 0.30, 95% CI: 0.15-0.59) was as “younger than actual age” and advanced the risk factor of poor sleep quality. In addition, feeling-for-their-age (OR: 0.44, 95% CI: 0.21 - 0.92) resulted in reduced risk factor of poor physical HRQOL. The risk factor of poor sleep quality was due to a patient with history of cancer. The factor for good sleep quality and the good factor for physical HRQOL were indications of feeling younger than the actual age

    With the purpose of revealing the biological effects of the X-ray irradiation the authors extracted phospholipids from the liver of irradiated animals and proved that this substance has the action to inhibit the growth of the bone marrow cells, the motility of pseudo-eosinophilis and the erythropoiesis in tissue culture, suggesting that the injury will mainly be induced by the toxic substances produced by irradiation.</p

    Purpose General surgeons at regional hospitals should have the primary trauma care skills necessary to treat critically ill trauma patients to withstand transfer. This study was conducted to identify a consensus on primary trauma care skills for general surgeons. Methods An initial list of acute care surgical skills was compiled, and revised by six trauma experts (acute care surgeons); 33 skills were nominated for inclusion in the Delphi consensus survey. Participants (councilors of the Japanese Society for Acute Care Surgery) were presented with the list of 33 trauma care skills and were asked (using web-based software) to rate how strongly they agreed or disagreed (using a 5-point Likert scale) with the necessity of each skill for a general surgeon. The reliability of consensus was predefined as Cronbach’s α ≥ 0.8, and trauma care skills were considered as primarily required when rated 4 (agree) or 5 (strongly agree) by ≥ 80% participants. Results There were 117 trauma care specialists contacted to participate in the Delphi consensus survey panel. In the 1st round, 85 specialists participated (response rate: 72.6%). In the 2nd round, 66 specialists participated (response rate: 77.6%). Consensus was achieved after two rounds, reliability using Cronbach’s α was 0.94, and 34 items were identified as primary trauma care skills needed by general surgeons. Conclusion A consensus-based list of trauma care skills required by general surgeons was developed. This list can facilitate the development of a new trauma training course which has been optimized for general surgeons

During the course, the authors carried out a taste survey of some Miso-soup by salt concentration on the attendants, and their consciousness of salt decreasing, staple food patterns, and state of intaking Miso-soup after the Seminar were also examined by questionnaire. (1) In the taste survey of some Miso-soup by salt concentration on the 920 subjects of regular and optional attendants, 56% answered 0.8% -NaCl Miso-soup as "just agreeable" or "salty", and 43% answered 1.0-1.5%-NaCl as "just agreeable" or "thin". In the taste preference by salt concentration was found a regional difference. (2) Examination by questionnaire of the consciousness of salt decreasing on the part of 716 "graduates" after the Seminar showed that compared with as high as 87.9% after the Seminar, 55% of the attendants paid attention to salt concentration and drank less salty Miso-soup before the Seminar. (3) The staple food patterns and the state of intaking Miso-soup in the attendants\u27 homes were also examined
