概要: Purpose: To investigate impact of the one‐carbon metabolism (OCM) on oocyte maturity and embryo development. Methods: Th is prospective study analyzed 18 women who agreed to participate. We measured the OCM biomarkers’ concentrations including Vitamin B12 (VB12), folic acid (FA), and homocysteine (Hcy) in serum and follicular fluid (FF), and assessed their correlation. We also evaluated the influence of such OCM biomarker concentrations in mono‐FF on oocyte maturation, fertilization, embryo quality, and consequent pregnancy after embryo transfers. Results: All biomarkers showed a high concentration variability in different follicles of each woman, but their mean levels correlated with the serum levels. Among the 106 collected oocytes, 92 were mature, 59 were fertilized, and 16 yielded good‐quality embryos. We performed 26 single embryo transfers, and 7 patients achieved clinical pregnancies. VB12 concentration (FF) was significantly lower in fertilized than unfertilized oocytes by univariate analysis. In multivariate logistic analysis, a significant correlation was found between FA concentration (FF) <14.25 ng/mL and good‐quality embryos and between Hcy concentration (FF) <4.9 nmol/mL and clinical pregnancy. Conclusion: OCM in FF may affect fertilization, embryo quality, and clinical pregnancy. 続きを見る

概要: This study records six Mantodea species from several islands in the Miyako Islands, including first records from some islands. Of the six Mantodea species, four species, i.e. Statilia nemoralis (Saussure, 1870), Tenodera fasciata (Olivier, 1792), T. angustipennis Saussure, 1869 and Hierodula patellifera (Audinet-Serville, 1839), are newly recorded from some adjacent islands of Miyako-jima Island, and two species, i.e. Mantis religiosa (Linnaeus, 1758) and Amantis nawai (Shiraki, 1908), were collected from previously recorded islands in the Miyako Is. Mantis religiosa and T. fasciata were primarily observed in open grasslands, and in contrast, T. angustipennis was mainly found around forest edges on Tarama-jima I. Few nymphs and an ootheca of S. nemoralis were found in grasslands on Ikema-jima I. and Kurima-jima I. Hierodula patellifera was the most abundant among mantis species during these surveys; a number of adults and a few nymphs of this species were observed in our expedition. For Amantis nawai, specimens of only the adult stage were observed, on the dried leaf litter of the forest floor on Miyako-jima I. In addition, three Mantodea species, M. religiosa, T. angustipennis and H. patellifera, were collected from UV-LED light trap set as a counterplan against Anomala albopilosa (Hope, 1839) (Coleoptera: Scarabaeidae) on Tarama-jima I. 続きを見る

概要: 筆者らは,これまで,Single-Input Multiple-Output (SIMO) や Multiple-Input Multiple-Output (MIMO)および大規模MIMOにおける受信アンテナのハードウェアコスト削減法とし てアンテナパターン多重 (Antenna Pattern Multiplexing; APM) 技術に着目して研究を行ってきた.本稿では,APMの原理について時変指向性利得として,周波数分割多重および符号分割多重に基づく周期波形を用いて説明を試み,単一のアンテナ系統から,複数の分離可能なアンテナ出力が得られることを示す.<br />We have been studied Antenna Pattern Multiplexing (APM) technique suitable for receivers of Single-Input Multiple-Output (SIMO), Multiple-Input Multiple-Output (MIMO), and massive MIMO systems. APM technique has potential to reduce the hardware cost of the receivers, for example, size of antenna, the number of required cables, cabling cost, calibration cost, maintenance cost, etc. In this paper, we try to explain the principle of APM with time-variable directional gain designed based on Frequency Division Multiplexing (FDM) and Code Division Multiplexing (CDM). Through the paper, we show how to obtain multiple distinguishable antenna outputs from a single Radio Frequency (RF) front-end. 続きを見る
