Abstract

Additional file 1 Appendix 1 Pilot study and PDF survey form. Appendix 2 Table S2: Original population and random samples selected from the original population who had inpatient or outpatient medical care in the study hospital at least once between February 1, 2018 and January 31, 2019. Appendix 3 Table S3: The number of patients of true positive (TP), false negative (FN), false positive (FP), and true negative (TN) and the sensitivity (SE), specificity (SP), positive predictive value (PPV) and negative predictive value (NPV), and the prevalence of the definition-positive patients for 32 claims-based definitions for RA when 39 patients with rheumatoid arthritis (RA) treated in a different hospital were included in the study population. Appendix 4: Sensitivity analysis to evaluate the effect of potential misclassification of patients with rheumatoid arthritis (RA) who did not meet “Definitions of possible cases of RA” (Table 1) as patients having no RA on the prevalence of definition–positive patients and the adjusted prevalence.

第27回宇宙利用シンポジウム (2011年1月24日-25日, 宇宙航空研究開発機構宇宙科学研究所相模原キャンパス), 相模原市, 神奈川県, The Twenty-seventh Space Utilization Symposium (January 24-25, 2011. Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)), Sagamihara, Kanagawa Japan, To discuss the necessity of space studies in mammal and to seek opportunities of the joint space missions for the animal experiments, we have organized the group for rodent studies with the joint members, which consist of the investigators familiar with the space experiment, in several working groups. We collaborated in the ground-based research using mice and held the joint meetings in 2010. These mice experiment was based on the tissue sharing program in space-utilizing experiment using the mouse drawer system organized by Italian Space Agency (2009), the key person is Dr. Ohira Y and colleagues, and he worked actively among the scientists in Japan and foreign country to maintain the scientific researches and the international collaboration without adequate government supports. From these activities, we cannot persuade ourselves that Japan Space Agency is in earnest for space utilization researches using rodents in the international space station (ISS), and it is thought that we will see to its opportunity ourselves ISS and/or small payload. However, we must require continuously JAXA to organize the project of rodent module in ISS, even if there are no chances to house the mice and rats in outer space. Other key rodent experiment is the investigation under less gravity environment such as the surface of Moon and Mars (Kumei Y). The human will arrive at Mars before next century, thus we also consider the conditions in mammal under the less gravity and more long-term stay in outer space including travel. At the present time, the crews on orbit of ISS are performing the many researches about space medicine in their bodies, and these investigations will produce the important knowledge regarding an exposure to long-duration microgravity and specific environments of the module in the near future. Probably, the new questions will be understood by these results, and the rodents investigations based on the human studies should be needed. Thus, we should perform continuously the ground-based experiments using rodents to lead young scientists interested in the space life science and medicine for next decade., 著者人数: 14人, Number of authors: 14, 資料番号: AA0065129046

Abstract

Autonomic nerve responses of human subjects were evaluated by frequency analysis of heart rate and pulse plethysmogram under linear acceleration applied to parallel (Z) and perpendicular (Y) to the body axis in supine posture. The acceleration applied were 0.25 G with sinusoidal frequencies, 0.1 to 0.17 Hz. The acceleration loading to Z-axis only induced additional frequency component in the power spectra obtained from heart rate and pulse plethysmogram at the foot finger skin, while no additional response was observed in Y-axis loading. The frequency dependency of the acceleration induced heart rate and pulse plethysmogram components suggested a resonance characteristic at higher frequency than 0.17 Hz. Iris diameter change during the acceleration loading measured by infrared light indicated a correlation to the acceleration. The results suggested that an autonomic hemodynamic modulation may arise from a feedback of low pressure receptors when the slow sinusoidal acceleration is loaded to the body axis., 資料番号: AA0046917003

Abstract

The development of efficient metal-free organic emitters with thermally activated delayed fluorescence (TADF) properties for deep-blue emission is still challenging. A new family of deep-blue TADF emitters based on a donor-acceptor architecture has been developed. The electronic interaction between donor and acceptor plays a key role in the TADF mechanism. Deep-blue OLEDs fabricated with these TADF emitters achieved high external quantum efficiencies over 19.2 % with CIE coordinates of (0.148, 0.098). [ABSTRACT FROM AUTHOR]
