Hemodynamic Effects of Intravenous Calcium Administration on Septic Shock Patients:A Retrospective Study

We evaluated the hemodynamics and outcomes of septic shock (SS) patients who did not respond to fluid resuscitation, after treatment with or without intravenous calcium. We retrospectively collected information on 154 eligible SS patients who were admitted to Fukuyama City Hospital Emergency Medical Center and did not respond to fluid resuscitation. To compare their degree of hemodynamic impairment, we compared the changes in the vasoactive-inotropic score (VIS) in the calcium-treated group (n＝112) and the noncalcium-treated group (n＝42). We compared the length of stay in the intensive care unit (ICU) and hospital, in-hospital deaths, 28-day deaths, and changes in the Sequential Organ Failure Assessment score within 72h of ICU admission between the 2 groups. Changes in the VIS at 1h after the baseline time were significantly greater in the calcium-treated group than in the noncalcium-treated group (1.41 vs. －1.25, respectively;p＜0.001). However, the changes in the VIS at 3, 6, 24, 48, and 72h did not differ between the 2 groups. The secondary outcomes also did not differ between the groups. Our findings indicate that calcium administered to SS patients might reduce their hemodynamic stabilization, but only for a short time after its administration

Emergence of a Euglena bioconvection spot controlled by non-uniform light

Microorganisms possess taxes, which are the behavioral response to stimuli. The interaction between taxis and fluid dynamic instability leads to a macroscopic flow called bioconvection. In this study, we demonstrated that an isolated, single, three-dimensional bioconvection cell can exist within Euglena suspension. The isolated convection cell was named a “bioconvection spot.” To reveal the formation of this bioconvection spot in a cylindrical container, position-control experiments were designed in a non-uniform light environment. Upon exposure of Euglena suspensions to varying light conditions with white and red regions, Euglena was determined to aggregate into the red (darker) region. This was attributed to its phototactic response of Euglena, causing its movement toward a darker environment and away from a strong light. Thus, the bioconvection spot was created by manipulating the local cell density of the suspension and the light environments. Using our experimental setup, we observed the structure of the spot and established that it radiated pulses of local cell densities of Euglena

Studies on Ecology and Behavior of Japanese Black Swallowtail Butterflies. III. Diurnal Tracking Behavior of Adults in Summer Generation

The habitat preference of the black swallowtail butterflies (BSB), Papilio helenus, P. protenor and P. memnon, was studied by mark-release-and-\u27resight\u27 method in Kodakasa-yama, Kochi, Japan. Flight behavior of BSB was little affected by this method. In P. helenus, males tended to prefer the edges of the forest instead of the treeless "gaps, " though their population interchange between gap and edge was at the same low rate. Both the gaps and the forest interior were utilized for roosting. P. protenor, on the other hand, tended to remain in the gaps and the interior where they fed and oviposited. Thus, the daily flight trajectory of P. protenor seemed roughly opposite that of P. helenus. P. memnon which flies by soaring and gliding, preferred an open or edge area of the forest. Their host plants and nectar plants are different from those of the other two species and grow mainly in open areas. Thus, P. protenor and P. memnon are the more typical inhabitants of forests and open areas among the three BSB species

The Lectures on the Development of Teaching Plans and Teaching Materials Tried in the Science Education Class in Master's Course, Okayama University

岡山大学大学院教育学研究科の理科教育専攻の講義として、教材開発・授業案開発をテーマとした新しい講義を試みたのでその報告を行う。本講義は、理科教育講座に所属する大学院生、理科教育講座の大学教員、附属学校の理科関係の教諭が三者協働で進めることが特徴である。課題設定、教材開発を含めた実践準備および実践を院生チームを組み遂行させ、さらに経験や専門性の異なる人材と論議を重ねて活動を進めることを通じ、将来、協働で学校現場の課題提案・解決を行うことのできる能力を養うことを目標とした。This is a report of the new type of lectures on the development of teaching plans and teaching materials attempted in the science class in the Master's Course, Okayama University. The lectures were conducted in collaboration of the graduate students and the academic staffs in the science education course, and the science teachers of the attached school of Okayama University. The graduate students were grouped into two teams of five or six people, assigned to decide on themes, prepare and practice the development of teaching plans and teaching materials. They conducted their activities discussing problems with people of different experience and specialty, thus developing the ability to jointly propose and solve problems at schools in future

Near-infrared Imaging Polarimetry of GGD 27: Circular Polarization and Magnetic Field Structures

Jungmi Kwon, et al, 'NEAR-INFRARED IMAGING POLARIMETRY OF GGD 27: CIRCULAR POLARIZATION AND MAGNETIC FIELD STRUCTURES', The Astrophysical Journal, 824:95 (14pp), June 2016. doi:10.3847/0004-637X/824/2/95. © 2016. The American Astronomical Society. All rights reserved.Near-infrared imaging polarimetry in the J, H, and K s bands was carried out for GGD 27 in the dark cloud Lynds 291. Details of an infrared reflection nebula associated with the optical nebulosity GGD 27 and the infrared nebula GGD 27 IRS are presented. Aperture photometry of 1263 point-like sources, detected in all three bands, was used to classify them based on a color-color diagram, and the linear polarization of several hundred sources was determined, with the latter used to map the magnetic field structure around GGD 27. This field, around GGD 27 IRS, appears to be associated with the extended CO outflow of IRAS 18162-2048 however, there are partly distorted or bent components in the field. The Chandrasekhar-Fermi method gives an estimate of the magnetic field strength as ˜90 μG. A region associated with GGD 27 IRS is discovered to have a circular polarization in the range of ˜2%-11% in the K s band. The circular polarization has an asymmetric positive/negative pattern and extends out to ˜ 120″ or 1.0 pc. The circular and linear polarization patterns are explained as resulting from a combination of dense inner and fainter outer lobes, suggesting episodic outflowPeer reviewedFinal Published versio
