Investigation and treatment of pulmonary embolism as a potential etiology may be important to improve post-resuscitation prognosis in non-shockable out-of-hospital cardiopulmonary arrest: report on an analysis of the SOS-KANTO 2012 study.

Background: The prognosis of non-shockable out-of-hospital cardiac arrest is worse than that of shockable out-of-hospital cardiac arrest. We investigated the associations between the etiology and prognosis of non-shockable out-of-hospital cardiac arrest patients who experienced the return of spontaneous circulation after arriving at hospital.

Methods And Results: All subjects were extracted from the SOS-KANTO 2012 study population.

Assessing injury severity in bicyclists involved in traffic accidents to more effectively prevent fatal bicycle injuries in Japan.

The objective of this study was to clarify the relationship between injury severity in bicyclists involved in traffic accidents and patient outcome or type of vehicle involved in order to propose effective measures to prevent fatal bicycle injuries. Hospital records were reviewed for all patients from 2007 to 2010 who had been involved in a traffic accident while riding a bicycle and were subsequently transferred to the Shock Trauma Center of Dokkyo Medical University Koshigaya Hospital. Patient outcomes and type of vehicle that caused the injury were examined.

Clinical efficacy and safety of arbekacin sulfate in patients with MRSA sepsis or pneumonia: a multi-institutional study.

Arbekacin (ABK) is an aminoglycoside and widely used in Japan for treatment of patients infected with methicillin-resistant Staphylococcus aureus (MRSA). Although, ABK has concentration-dependent antibacterial activity, the peak serum concentration (C (peak)) of ABK has not yet been fully investigated as an indicator of the efficacy of ABK. The present study was conducted in patients admitted to hospitals affiliated with the ABK Dose Finding Study Group, between October 2008 and June 2011, who had pneumonia or sepsis, the cause of which was identified or suspected to be MRSA.

Formation of ionic bonds between a fatty-acid Langmuir-Blodgett monolayer and a zinc oxide substrate.

A fatty-acid Langmuir-Blodgett (LB) monolayer ionically adsorbed to the substrate has been prepared by adopting ZnO-based conductor and pure water respectively as the substrate and subphase. Ionization of the fatty-acid molecules has been detected by infrared reflection-absorption spectroscopy (IR-RAS), which is enabled by the condensed free electrons in the doped ZnO substrate. On the contrary, IR-RAS measurements have indicated that fatty-acid molecules transferred onto Au and indium-tin-oxide substrates from a pure-water surface are not ionized.

Adsorption of anionic nanosheets from their dilute colloidal suspensions onto gas-liquid interfaces with and without a Langmuir film of cationic surfactant.

The adsorption of [(Ca(2)Nb(3)O(10))(-)](n) (CNO) polyanionic nanosheets from their dilute colloidal suspensions onto gas-liquid interfaces with and without a cationic [N(CH(3))(2)(C(18)H(37))(2)](+) (DOA) surfactant film has been experimentally investigated. Our concern has been focused particularly on their dynamical aspects, which can be observed owing to the long specific time of the adsorption. The theoretical framework of the Langmuir adsorption model has enabled a quantitative analysis of the observed data, and that analysis has indicated that the presence of a positively charged Langmuir film enhances the ratio of the adsorption and desorption rate constants by approximately 30 times.

Mass-casualty triage training for international healthcare workers in the Asia-Pacific region using manikin-based simulations.

Introduction: More than half of the world's disasters occur in the Asia-Pacific region. A simulation-based exercise to teach healthcare workers prehospital triage, tagging, and treatment methods was used to link disaster management theory to practice with a student-centered, hands-on educational activity. Various strategies for teaching disaster health education have been advocated, and best-practice disaster education models continue to be sought.

Activation of abscisic acid biosynthesis in the leaves of Arabidopsis thaliana in response to water deficit.

It is well known that endogenous abscisic acid (ABA) levels increase rapidly in response to drought stress and that this induces stomatal closure. In Arabidopsis thaliana, ABA levels increased rapidly in the leaves and roots when intact wild-type whole plants were exposed to drought stress. However, if the leaves and roots were separated and exposed to drought independently, the ABA level increased only in the leaves.

Drought induction of Arabidopsis 9-cis-epoxycarotenoid dioxygenase occurs in vascular parenchyma cells.

The regulation of abscisic acid (ABA) biosynthesis is essential for plant responses to drought stress. In this study, we examined the tissue-specific localization of ABA biosynthetic enzymes in turgid and dehydrated Arabidopsis (Arabidopsis thaliana) plants using specific antibodies against 9-cis-epoxycarotenoid dioxygenase 3 (AtNCED3), AtABA2, and Arabidopsis aldehyde oxidase 3 (AAO3). Immunohistochemical analysis revealed that in turgid plants, AtABA2 and AAO3 proteins were localized in vascular parenchyma cells most abundantly at the boundary between xylem and phloem bundles, but the AtNCED3 protein was undetectable in these tissues.

Transient expression of AtNCED3 and AAO3 genes in guard cells causes stomatal closure in Vicia faba.

Abscisic acid (ABA) regulates stomatal closure in response to water loss. Here, we examined the competence of guard cells to synthesize ABA, using two Arabidopsis ABA biosynthetic enzymes. 35S pro::AtNCED3-GFP and AAO3-GFP were introduced into guard cells of broad bean leaves.

Effect of ABA upon anthocyanin synthesis in regenerated torenia shoots.

To elucidate the mechanism of anthocyanin synthesis induction concomitant with chlorophyll degradation, we established a system in which anthocyanin synthesis and degradation of chlorophyll in regenerated torenia (Torenia fournieri) shoots was induced on medium containing 7% sucrose. Here, we studied the effect of several plant-growth regulators on anthocyanin synthesis and the degradation of chlorophyll in the torenia shoot regenerating system. Exogenous abscisic acid (ABA) could induce anthocyanin synthesis and chlorophyll senescence in regenerating torenia shoots on the medium containing a low concentration of sucrose (1.

High incidence of ischemic necrosis of the gluteal muscle after transcatheter angiographic embolization for severe pelvic fracture.

Background: After transcatheter angiographic embolization (TAE), massive gluteal muscle necrosis was found in patients during open reduction and internal fixation for pelvic fracture.

Methods: In our six patients, magnetic resonance imaging (MRI) scans obtained 1 and 4 weeks after TAE demonstrated ischemic damage of the gluteal muscle.

Results: Total reopening of the embolized artery was confirmed in only one case on the second angiogram obtained 1 month after TAE.

Cold acclimation in bryophytes: low-temperature-induced freezing tolerance in Physcomitrella patens is associated with increases in expression levels of stress-related genes but not with increase in level of endogenous abscisic acid.

Bryophyte species growing in areas in which temperatures fall below zero in winter are likely to have tolerance to freezing stress. It is well established in higher plants that freezing tolerance is acquired by exposure to non-freezing low temperatures, accompanied by expression of various genes and increases in levels of the stress hormone abscisic acid (ABA). However, little is known about the physiological changes induced by cold acclimation in non-vascular plants such as bryophytes.

Spectroscopic study of J aggregates of amphiphilic merocyanine dyes formed in their pure Langmuir films.

It is known that an amphiphilic merocyanine dye, 3-carboxymethyl-5-[2-(3-octadecyl-2(3H)- benzothiazolylidene)ethylidene]-2-thioxo-4-thiazolidinone (DS) and its derivatives DSe and 6MeDS form J aggregates under the presence of metallic cations, although the dyes' static dipole moments must be favorable for H aggregates. A metal-free J aggregate of 6MeDS has been generated in its pure Langmuir films and transferred onto CaF2 substrates to investigate the molecular environment around the carboxylic group born by the dye. Combining visible and infrared spectroscopy, geometrical consideration based on ab initio calculations, and simulation of the excitation energy, a structural model of this J aggregate has been proposed.

Simultaneous analysis of plural samples in a CE-CL detector possessing micro-space area for reaction/detection.

Plural samples were simultaneously analyzed in a capillary electrophoresis (CE)-chemiluminescence (CL) detector system, taking advantage of a micro-space area for reaction/detection at the tip of the capillary. The CL reaction of 1,10-phenanthroline and hydrogen peroxide was adopted and a Cu(II) sample was used as a model. Three different length capillaries were inserted into a flow-type CL detection cell made of a Teflon tube.

Effects of ethylene and abscisic acid upon heterophylly in Ludwigia arcuata (Onagraceae).

In this study, we examined the effects of ethylene and abscisic acid (ABA) upon heterophyllous leaf formation of Ludwigia arcuata Walt. Treatment with ethylene gas resulted in the formation of submerged-type leaves on terrestrial shoots of L. arcuata, while treatments with ABA induced the formation of terrestrial-type leaves on submerged shoots.

[Assessment of peripheral blood perfusion during open heart surgery with sublingual PCO2 measured by ISFET-PCO2 sensor].

Sublingual tissue PCO2 (PSLCO2) was continuously monitored with an ISFET-based PCO2 sensor during and after the open-heart surgery under cardiopulmonary bypass (CPB) in order to study the effect of CPB on the peripheral blood perfusion. In addition, PSLCO2 monitoring was carried out in several cases of off-pump CABG. In the cases of open-heart surgery with CPB, PSLCO2 increased from 35.

[Pathophysiologic changes in trauma patients and indications of damage control surgery].

Damage control surgery has become an inevitable strategy in the treatment of severely traumatized patients. Rationale for the DCS is the fact that the mortality in surgical patients who developed hypothermia, acidosis, and coagulopathy (lethal triad) is extremely high unless patients' physiologic stability was reestablished. DCS is usually indicated when patient shows signs of lethal triad during surgical operation.
