Background Obesity is the most common metabolic disease in the world. However, the relationship between obesity and lung function is not fully understood. Although several longitudinal studies have shown that increases in body weight can lead to reductions in pulmonary function, whether this is the case with the Japanese population and whether high body mass index （BMI） status alone represents an appropriate predictor of obstructive lung dysfunction remains *** purpose of present study was to estimate the effect of BMI on lung function measured by spirometry of Japanese patients in general clinics. We measured BMI and performed spirometry on screening patients who had consulted general *** Subjects comprised 1231 patients ≥40 years of age （mean age （65.0±12.0） years, 525 men, 706 women） who had consulted clinics in Nagasaki Prefecture, Japan, for non-respiratory disease. BMI was calculated and lung function was measured by *** BMI was found to be positively correlated with forced expiratory volume in 1 second （FEV1）/forced vital capacity （FVC） in men and with maximum mid-expiratory flow （MMF） in all subjects. Following adjustment for relevant factors, a significant positive correlation between BMI and FEV1/FVC was identified for all subjects. Comparison between subjects with normal BMI （18.5-25.0） and higher BMI （25.1-30.0） also demonstrated that FEV1/FVC and percentage of predicted maximum mid-expiratory flow （%MMF） were significantly higher in the latter *** In a population without marked respiratory disease, higher BMI subjects showed less obstructive pulmonary dysfunction compared to normal BMI subjects. High BMI status alone may be inappropriate as a predictor of obstructive lung dysfunction, particularly in populations with a low prevalence of obesity.

Clinical Outcomes of Patients Who Perform High-Load Activities after Total Hip Arthroplasty in Snowy Agricultural Areas

Surgical Science 2018年第8期9卷 248-255页

Background: In snowy agricultural areas, weeding and snow shoveling are essential activities, and sports activities are common recreational activities. Clarifying the relationships between the degrees of these activities after total hip arthroplasty (THA) and the clinical outcomes may enable us to predict the results of THA for high-load activity patients. Methods: The subjects were 227 post-THA patients who were followed up between 2012 and 2014. Patient-reported outcomes were investigated by the Japanese Orthopaedic Association Hip Disease Evaluation Questionnaire (JHEQ) and a questionnaire on postoperative activity. In addition, the Japanese Orthopaedic Association Hip Score (JOA score) was used to quantify hip function. Results: Patients who resumed activities had significantly higher JOA and JHEQ scores than patients who had given up their activities. However, 25.8% of patients had not resumed weeding with a squatting posture. Furthermore, 20% had not resumed sports activities. The most common reason for giving up these activities was fear of implant failure. Conclusions: If the patients were informed that there is no problem restarting their activities after THA, the patients could resume activities and their clinical outcomes may be improved.

A novel Radio On Fiber(ROF) access is proposed and demonstrated which enables the pico-cell Base Station (BS) for high-speed wireless communications to eliminate external electric power supply facilities. We demonstrated 2.4-GHz band radio signal transmission through the BS without external electric power supply. The electrical power used for BS circuit is feeded by optical power over optical fiber from central station.

Plants have a multilayered immune system that includes pattern-triggered immunity(PTI)and effector-triggered immunity(ETI)to cope with pathogen attacks[1].PTI,also known as basal innate immunity,is initiated by the perception of microbe-/pathogen-associated molecular patterns(MAMPs/PAMPs)by pattern recognition receptors(PRRs).PRRs are cell surface-localized kinase complexes comprising receptor-like kinases(RLKs)and receptorlike proteins(RLPs).The majority of characterized RLKs structurally possess a variable extracellular domain(ECD),a single transmembrane(TM)region,and an intracellular kinase domain(KD),whereas RLPs lack an intracellular *** three most prevalent types of PRR ectodomains are leucine-rich repeats(LRR),multiple lysin motifs(LysM),and lectin *** the early stages of pathogen infection,PRR signaling is rapidly activated and triggers a series of immune responses,such as ROS bursts,callose deposition,and pathogenesis-related(PR)gene expression,to repel pathogenic microorganisms.

Systematical Experiment for Optimal Design of Vibrating Flow Pump with Jelly-fish Valve

引用

Journal of Bionic Engineering 2016年第1期13卷 166-179页

作者： Satoyuki kawano Saki Miyagawa Atsushi Shirai Graduate School of Engineering Science Osaka University Osaka 560-8531 Japan Institute of Fluid Science Tohoku University Sendai 980-8577 Japan

The fundamental characteristics and the flow mechanism of a Vibrating Flow Pump （VFP） with a jelly-fish valve, which can be applied to a novel artificial heart, were studied theoretically and experimentally. By using water as the working fluid, the measurement methodology for the typical unsteady flow for VFP was developed here. The effects of the frequency, amplitude and inner diameter of the vibrating pipe, and thickness of the silicone rubber sheet of the jelly-fish valve on the basic per- formance of VFP were systematically investigated. A high-speed observation technique and simple theoretical model analysis were also introdueed for further detailed discussion. Quantitative contributions of the individual parameters to the pumping performance were shown through the experiment, which would give us essential knowledge for establishing design criteria of VFE The theoretical model, which agreed with the experiment and the high-speed observation, elucidated the pumping mechanism with respect to the role of inertia of the inner fluid.

作者： kawano Nobuyuki VRAD/RSAT Team LALT Team Shanghai Astronomical Observatory

Japanese lunar explorer SELENE (KAGUYA) was equipped with 14 instruments for various measurements of the Moon. Three of these instruments took geodetic measurements of the Moon. These were two sub-satellites and a laser altimeter. The main results obtained by the instruments are: (1) precise orbit determination with an accuracy of ten meters by Doppler and same-beam VLBI; (2) the first precise gravity fields on the lunar far side by 4-way Doppler measurements; (3) the first topography in latitudes higher than 86 degrees; (4) a global map of the gravity anomaly by using the global topography and the global gravity fields; (5) a global map of the lunar crustal thickness and (6) an illumination rate map in the north and south polar regions.
