Incommensurately Modulated Crystal Structure and Photoluminescence Properties of EuO- and PO-Doped CaSiO Phosphor.

We prepared four types of EuO- and PO-doped CaSiO phosphors with different phase compositions but identical chemical composition, the chemical formula of which was (CaEu☐)(SiP)O (☐ denotes vacancies in Ca sites). One of the phosphors was composed exclusively of the incommensurate (IC) phase with superspace group (00)00 and basic unit-cell dimensions of = 0.68004(2) nm, = 0.

Influences of hyperlipidemia history on stroke outcome; a retrospective cohort study based on the Kyoto Stroke Registry.

Background: Although hyperlipidemia is known as a risk factor of stroke, its effects on the outcome are unknown. The aim of the study is to clarify the influences of hyperlipidemia on the stroke early outcome by estimating odds ratio (OR) for sequelae requiring care and hazard ratio (HR) for death.

Methods: A total of 12617 stroke patients registered in the Kyoto Stroke Registry with information on a hyperlipidemia history.

Weekly variations of stroke occurrence: an observational cohort study based on the Kyoto Stroke Registry, Japan.

Objectives: Understanding the temporal pattern of stroke onset and exploring the possible triggers are important strategies to reducing the incidence of stroke. If stroke occurs frequently on a specific day of the week, it is assumed that other factors, that is, 'triggering factors', induce stroke. The aim of the study is to investigate differences in the incidences of stroke among days of the week.

Softening due to disordered grain boundaries in nanocrystalline Co.

Nanocrystalline Co consisting of fcc and hcp phases was processed by electrodeposition, and its mechanical properties were investigated by hardness tests. In addition, high-resolution transmission electron microscopy observations and molecular dynamics (MD) simulations were performed to investigate the grain boundary structure and dislocation nucleation from the grain boundaries. A large amount of disorders existed at the grain boundaries and stacking faults were formed from the grain boundaries in the as-deposited Co specimen.

Speech disturbance at stroke onset is correlated with stroke early mortality.

Background: Speech disturbance is a common symptom of stroke and is important as a prompt identifier of the event. The frequency of the symptom among each stroke subtype, differences between patients with and without speech disturbance and its correlation to early mortality remain unclear.

Methods: The Kyoto prefecture of Japan has established a registry to enroll new stroke patients in cooperation with the Kyoto Medical Association and its affiliated hospitals.

Synthesis of New RE Doped LiTaTiO₃ (RE: Eu, Sm, Er, Tm, and Dy) Phosphors with Various Emission Colors.

New phosphors with various emission colors for RE doped LiTaTiO₃ (LTT) (RE: Eu, Sm, Er, Tm, and Dy) were synthesized by electric furnace at 1423 K for 15 h. The microstructure of the host material and the photoluminescence (PL) property were determined and compared to those of RE doped LiNbTiO₃ (LNT) In the LTT phosphor, the highest PL intensity was achieved for the mixture composition LiTaTiO₃ with a LiTaO₃ structure, although it has an M-phase superstructure. In the LTT host material, the effective activators were Eu and Sm ions, in contrast to the LNT host material.

The eye response test alone is sufficient to predict stroke outcome--reintroduction of Japan Coma Scale: a cohort study.

Objectives: Prompt assessment of consciousness levels is vitally important during the emergency care of stroke patients. The Japan Coma Scale (JCS) is a one-axis coma scale published in 1974 with outstanding simplicity. The hypothesis is that JCS is sufficient to predict stroke outcome.

Characteristics, risk factors and mortality of stroke patients in Kyoto, Japan.

Objectives: The aim of the study was to evaluate the characteristics, risk factors and outcome of recent stroke patients in Kyoto, Japan.

Design: We analysed stroke patients in the registry with regard to their characteristics, risk factors and mortality. Cox proportional hazards regressions were used to calculate adjusted HRs for death.

Vomiting should be a prompt predictor of stroke outcome.

Background: To predict the outcome of stroke at an acute stage is important but still difficult. Vomiting is one of the commonest symptoms in stroke patients. The aim of this study is threefold: first, to examine the percentage of vomiting in each of the three major categories of strokes; second, to investigate the association between vomiting and other characteristics and third, to determine the correlation between vomiting and mortality.

Imma perovskite-type oxynitride LaTiO2N: structure and electron density.

We present the first example of Imma perovskite-type oxynitride. LaTiO(2)N was found to have an Imma perovskite-type structure with a(0)b(-)b(-) tilt system. The Ti-(O,N) covalent bonding and existence of N atoms are responsible for the reduced band gap of LaTiO(2)N photocatalyst.

[Dietary fatty acid intake and concentrations in serum and erythrocyte membranes of students with allergic disease].

Purpose: An attempt was made to utilize accumulated scientific evidence for nutritional guidance concerning dietary fatty acids (FAs) for students with allergic diseases

Methods: A questionnaire survey on dietary fatty acid intake was conducted with 128 women students aged 19-20. In addition to hematological and physical examinations, fatty acid analyses were performed with serum and erythrocyte membrane samples using gas chromatography. Based on the answers to questions about allergic diseases, the subjects were divided into three groups (59 healthy students, 45 with previous experience of allergies, and 24 with allergies).

Temperature response of mesophyll conductance. Implications for the determination of Rubisco enzyme kinetics and for limitations to photosynthesis in vivo.

CO(2) transfer conductance from the intercellular airspaces of the leaf into the chloroplast, defined as mesophyll conductance (g(m)), is finite. Therefore, it will limit photosynthesis when CO(2) is not saturating, as in C3 leaves in the present atmosphere. Little is known about the processes that determine the magnitude of g(m).

An adenylyl cyclase, CyaA, of Myxococcus xanthus functions in signal transduction during osmotic stress.

An adenylyl cyclase gene (cyaA) present upstream of an osmosensor protein gene (mokA) was isolated from Myxococcus xanthus. cyaA encoded a polypeptide of 843 amino acids with a predicted molecular mass of 91,187 Da. The predicted cyaA gene product had structural similarity to the receptor-type adenylyl cyclases that are composed of an amino-terminal sensor domain and a carboxy-terminal catalytic domain of adenylyl cyclase.
