Stage III Chorioamnionitis is Associated with Reduced Risk of Severe Retinopathy of Prematurity.

Objective: To identify whether histologically confirmed chorioamnionitis (hCAM) is associated with development of retinopathy of prematurity (ROP).

Study Design: We retrospectively analyzed 2 different cohorts. Cohort 1 was the national database of newborns in Japan born at ≤1500g or <32 weeks' gestation (January 2003 through April 2021, n = 38 013).

Transcriptome analysis of umbilical cord mesenchymal stem cells revealed fetal programming due to chorioamnionitis.

Although chorioamnionitis (CAM) has been demonstrated to be associated with numerous short- and long-term morbidities, the precise mechanisms remain unclear. One of the reasons for this is the lack of appropriate models for analyzing the relationship between the fetal environment and chorioamnionitis and fetal programming in humans. In this study, we aimed to clarify the fetal programming caused by CAM using the gene expression profiles of UCMSCs.

Spectroscopic analysis in molecular simulations with discretized Wiener-Khinchin theorem for Fourier-Laplace transformation.

The Wiener-Khinchin theorem for the Fourier-Laplace transformation (WKT-FLT) provides a robust method to obtain the single-side Fourier transforms of arbitrary time-domain relaxation functions (or autocorrelation functions). Moreover, by combining an on-the-fly algorithm with the WKT-FLT, the numerical calculations of various complex spectroscopic data in a wide frequency range become significantly more efficient. However, the discretized WKT-FLT equation, obtained simply by replacing the integrations with the discrete summations, always produces two artifacts in the frequency-domain relaxation function.

High dispersion and oxygen reduction reaction activity of CoO nanoparticles on platelet-type carbon nanofibers.

In this study, platelet-type carbon nanofibers prepared by the liquid phase carbonization of polymers in the pores of a porous anodic alumina template were used to prepare the CoO/carbon electrocatalysts. For comparison, CoO nanoparticles were also deposited on multiwall carbon nanotubes (MWCNTs). Both the nitrogen-free platelet-type carbon nanofibers (pCNFs) and the nitrogen-containing analogue (N-pCNFs) exhibited better dispersion and higher amount of deposited CoO nanoparticles compared to the MWCNTs.

In situ semi-quantitative analysis of zinc dissolution within nanoporous silicon by X-ray absorption fine-structure spectroscopy employing an X-ray compatible cell.

The in situ study of the discharge process in a zinc-based half-cell employing a porous electrode as a structural scaffold is reported. The in situ characterization has been performed by synchrotron X-ray absorption fine-structure spectroscopy and, for this purpose, an inexpensive, simple and versatile electrochemical cell compatible with X-ray experiments has been designed and described. The experimental results reported here have been employed to semi-quantify the dissolved and undissolved zinc species during the discharge, allowing the cell feasibility to be tested and to better understand the functioning of the zinc half-cell based on porous electrodes.

Dynamic manipulation of the local pH within a nanopore triggered by surface-induced phase transition.

Manipulating the local pH within nanoconfinement is essential in nanofluidics technology and its applications. Since the conventional strategy utilizes the overlapping of an electric double layer formed for charge compensation by protons near a negatively charged pore-wall surface, pH variation within a pore is limited to the acidic side. To achieve the variation at the alkaline side, we developed a system comprising a hydrophobic pore-wall surface and aqueous solution containing hydrophobic cations.

Anamorelin (ONO-7643) in Japanese patients with non-small cell lung cancer and cachexia: results of a randomized phase 2 trial.

Purpose: Cancer cachexia is characterized by decreased body weight (mainly lean body mass [LBM]) and negatively impacts quality of life (QOL) and prognosis. Anamorelin (ONO-7643) is a novel selective ghrelin receptor agonist under development for treating cancer cachexia.

Methods: In this double-blind, exploratory phase 2 trial, we examined the efficacy and safety of anamorelin in Japanese patients (n = 181) with non-small cell lung cancer (NSCLC) and cancer cachexia (≥5 % weight loss within the previous 6 months).

The structural classification of the highly disordered crystal phases of [Nn][BF4], [Nn][PF6], [Pn][BF4], and [Pn][PF6] salts (Nn(+) = tetraalkylammonium and Pn(+) = tetraalkylphosphonium).

The structures of 16 symmetric tetraalkylammonium (Nn(+)) and tetraalkylphosphonium (Pn(+)) salts ([Nn][BF4], [Nn][PF6], [Pn][BF4], and [Pn][PF6], where n = 1 to 4, and denotes the number of carbon atoms in each alkyl chain) have been investigated by X-ray diffraction in order to elucidate the effect of ion size on the disordered structure of organic salts. All the salts exhibit one or more solid-solid phase transitions in differential scanning calorimetric curves. Powder X-ray diffraction revealed that the highest temperature solid phase of these salts belongs to a crystal system with a high cubic or hexagonal symmetry.

[Assessment of contracted bladder following intravesical instillation of BCG (Japan)].

We assessed a situation concerning contracted bladder following intravesical instillation of BCG(Japan), to investigate how the disease could be prevented. Between March 1997 and June 2010, we selected 20 patients with clinically or pathologically confirmed contracted bladder to participate in the study. The incidence of contracted bladder tended to be higher for patients who had received more than 5 doses of BCG.

[Osteitis as a complication of BCG vaccination].

Objectives: To investigate the incidence and increasing tendency of osteitis after BCG vaccination and, in addition, its clinical features, diagnostic methods and results of treatment.

Subjects: 22 cases of Japanese children who received BCG vaccination between 1998 and 2007 and developed osteitis, and were reported in medical journals or meetings.

Results And Discussion: Incidence was very low, 0.

To investigate the molecular characteristics of bacillus Calmette-Guérin (BCG) vaccines, the complete genomic sequence of Mycobacterium bovis BCG Tokyo 172 was determined, and the results were compared with those for BCG Pasteur and other M. tuberculosis complex. The genome of BCG Tokyo had a length of 4,371,711bp and contained 4033 genes, including 3950 genes coding for proteins (CDS).

The EEG measurement technique under exercising.

Our purpose of the research is a development of the detecting method of EEG under exercising. Usually, measuring EEG is done in the quiet state. In case of the measuring EEG under exercising, a movement of the body causes vibration of electrodes and artifact for the EEG.

Identification of two subpopulations of Bacillus Calmette-Guérin (BCG) Tokyo172 substrain with different RD16 regions.

Two types of colonies with different morphologies (smooth: S and rough: R) formed when Bacillus Calmette-Guérin (BCG) Tokyo172 substrain was cultured on Middlebrook 7H10 agar medium, and their genotypes were analyzed by multiplex PCR on five RD regions and SenX3-RegX3. In most cases these two colony types had different genotypes, i.e.

Modified multiplex PCR for identification of Bacillus Calmette-Guérin substrain Tokyo among clinical isolates.

When an adverse reaction occurs and a mycobacterial species is isolated from a person vaccinated with Bacillus Calmette-Guérin (BCG) or a patient receiving BCG immunotherapy, it is essential to identify whether the isolate is BCG or another mycobacterial species. However, differentiation of BCG from other members of Mycobacterium tuberculosis complex has been very difficult. Using several specific primer-pairs, Bedwell et al.

Purpose: We investigated the preparation of bacillus Calmette-Guerin (BCG) Tokyo172 substrain (Japan BCG Laboratory, Ltd., Tokyo, Japan) on the characteristics of bacilli and antitumor activity in a mouse model in comparison with a preparation of the Connaught substrain (Aventis Pasteur, Ltd., Toronto, Ontario, Canada).

Molecular dynamics simulation of polymer crystallization from an oriented amorphous state.

The molecular process of crystallization from an oriented amorphous state was reproduced by molecular dynamics simulation for a realistic polyethylene model. The initial oriented amorphous state was obtained by uniaxially drawing an isotropic glassy state at 100 K. By the temperature jump from 100 K to 330 K, there occurred crystallization into the fiber structure, during the process of which we observed the developments of various order parameters.
