BACKGROUND Anterior cutaneous nerve entrapment syndrome(ACNES)is a condition mani-festing with pain caused by strangulation of the anterior cutaneous branch of the lower intercostal *** case report aims to provide new insight into the selection of peripheral nerve blocks for the ACNES *** SUMMARY A 66-year-old woman manifested ACNES after a robot-assisted distal *** ultrasound-guided rectal sheath block was effective for pain triggered by the port ***,the sudden severe pain,which radiated laterally from the previous site,remained.A transversus abdominis plane block was performed for the remaining pain and effectively relieved *** In this case,the trocar port was inserted between the rectus and transverse abdominis *** intercostal nerves might have been entrapped on both sides of the rectus and transversus abdominis ***,rectus sheath and transverse abdominis plane blocks were required to achieve complete pain *** the best of our knowledge,this is the first report on use of a combination of rectus sheath and transverse abdominis plane blocks for pain relief in ACNES.

Background: The coronavirus disease (COVID-19) pandemic has impacted perinatal women’s mental health. However, protective factors associated with depression among pregnant Japanese women during the pandemic have not been reported. Purpose: The present study investigated the risk and protective factors associated with depression and anxiety among pregnant women during the COVID-19 pandemic. Methods: An online questionnaire was administered to 157 pregnant women between October 2022 and May 2023 at two general hospitals in Japan. The Japanese versions of the Patient Health Questionnaire-9 (PHQ-9) and General Anxiety Disorder-7 (GAD-7) were used to assess symptoms of depression and anxiety. The χ2 test or Fisher’s exact test and multivariate logistic regression model were used to examine factors associated with depression and anxiety among pregnant women. Results: Overall, 47.1% and 35.7% of the pregnant women reported depressive and anxiety symptoms, respectively. A “history of mental illness” was a risk factor for depression and anxiety among pregnant women during the COVID-19 pandemic. Additionally, unmarried status was a risk factor for anxiety among pregnant women, whereas outdoor and indoor exercises were protective factors against depression and anxiety, respectively. Conclusions: Exercise may have protected pregnant women from depression and anxiety during the COVID-19 pandemic. Encouraging exercise may help maintain the mental health of pregnant women who do not have exercise restrictions.

人类创造并传承至今的历史,启示着人类社会的理想状态和前进方向。此中,文化遗产更被誉为人类社会的指南针,是历史的重要物证。尤其近年来,政府极力主张它们应作为旅游资源被有效利用,许多地方率先加强行政效能到地方文化的振兴中,依托当地历史文化,通过世界遗产名录活动的开展和文化遗产的认定,达到地方振兴的目的。像这样将文化遗产作为媒介,举办地域认同感的文化活动也成为近年的趋势。

A case study of seismic response of an earth embankment foundation on liquefiable soils in Kansai area,western Japan was presented. Based on a calibrated cyclic elasto-plastic constitutive model for liquefiable sand and Biot dynamic coupled theory,the seismic analysis was carried out by using a dynamic effective stress finite element method under plane strain condition. A recent design study was illustrated in detail for a river earth embankment subjected to seismic excitation on the saturated deposits with liquefiable sands. Simulated results of the embankment foundation during liquefaction were obtained for acceleration,displacement,and excess pore water pressures,which were considered to yield useful results for earthquake geotechnical design. The results show that the foundation soil reaches a fully liquefied state with high excess pore pressure ratios approaching to 1.0 due to the earthquake shaking. At the end of the earthquake,the extensive liquefaction causes about 1.0 m lateral spreading at the toe and 60 cm settlement at the crest of the earth embankment.

We examined wave phenomena pertinent to water in a rotating,laterally oscillating cylindrical *** particular,we measured the time-dependent dynamic water pressure and pressure change by fast Fourier transform *** swirling of water in the container had three frequency components;the frequency responses of each frequency component are reported *** swirling occurs in a rotating cylindrical container,it was found that the wave rotating in the same direction as the rotation of the cylindrical container and the wave rotating in the opposite direction to the cylindrical container exist at the same *** swirling direction was determined by the relationship of these magnitude.

In the mammalian brain, four neurotrophins have been identified： nerve growth factor （NGF）, brain-derived neurotrophic factor （BDNF）, neurotrophin-3 （NT-3） and neurotrophin-4/5 （NT-4/5）. NGF exerts an important role in the development and functions of the central and peripheral nervous system. However, it has recently been documented that several types of immune cells, such as mast ceils, iymphocytes, basophils and eosinophils, produce, store and release NGF. Accumulating preclinical and clinical data indicate that dysfunctions of NGF and the other neurotrophins may contribute to impaired immune responses and concentration of NGF frequently correlates with disease severity. Thus, the aim of this study was to elucidate the potential signaling mechanisms of cytokineneurotrophins interactions contributing to increased NGF levels. Our data show that the transcription factor NF-κB plays a pivotal role in regulating B-cell-derived NGF expression.

Synchrotron X-rays can be a useful tool to investigate electron accelera- tion at young supemova remnants （SNRs）. At present, since the magnetic field con- figuration around the shocks of SNRs is uncertain, it is not clear whether electron acceleration is limited by SNR age, synchrotron cooling, or even escape from the ac- celeration region. We study whether the acceleration mechanism can be constrained by the cutoff shape of the electron spectrum around the maximum energy. We derive analytical formulae of the cutoff shape in each case where the maximum electron en- ergy is determined by SNR age, synchrotron cooling and escape from the shock. They are related to the energy dependence of the electron diffusion coefficient. Next, we discuss whether information on the cutoff shape can be provided by observations in the near future which will simply give the photon indices and the flux ratios in the soft and hard X-ray bands. We find that if the power-law index of the electron spectrum is independently determined by other observations, then we can constrain the cutoff shape by comparing theoretical predictions of the photon indices and/or the flux ratios with observed data which will be measured by NuSTAR and/or ASTRO-H. Such study is helpful in understanding the acceleration mechanism. In particular, it will supply another independent constraint on the magnetic field strength around the shocks of SNRs.

An efficient implicit procedure for the Discontinuous Galerkin (DG) methodis developed utilizing a pointwise relaxation algorithm. In the pointwise relaxation,those contributions from the degrees of freedom in own computational cell are accounted for in the implicit matrix inversion. The resulting scheme is shown to be stablewith very large CFL numbers for both the Euler and the Navier-Stokes equations fortypical test problems. In order to achieve a faster convergence, efforts are also madeto reduce computing time of the present method by utilizing a p-multigrid schemeand also by solving a simplified matrix instead of a fully loaded dense matrix in theimplicit matrix inversion. A superior performance of the present implicit DG methodon the parallel computer using up to 128 PEs is shown in terms of readily achievablescalability and high parallel efficiency. The RANS simulation of turbulent flowfieldover AGARD-B model is carried out to show the convergence property and numericalstability of the present implicit DG method for engineering applications.
