Objective: We aimed to develop and validate a deep learning system for fully automated segmentation of abdominal muscle fat areas on computed tomography (CT) images. Materials Methods:A convolutional network-based was developed using training dataset 883 CT scans from 467 subjects.Axial images obtained at the inferior endplate level 3rd lumbar vertebra were used analysis.Manually drawn maps skeletal muscle, visceral fat, subcutaneous created serve as ground truth data.The performance...
Quantification of abdominal muscle mass by cross-sectional imaging has been increasingly used to diagnose sarcopenia; however, the technical method for quantification not standardized yet. We aimed determine an optimal measure area.Among 50 consecutive subjects who underwent CT and MRI possible liver donation, total area (TAMA) psoas (TPA) at L3 inferior endplate level were measured two blinded readers. Inter-scan agreement between inter-reader readers evaluated using intraclass correlation...
Terahertz (THz) imaging is a nondestructive, label-free, rapid technique which gives the possibility of real-time tracing drugs within skin. We evaluated feasibility THz dynamic for visualizing serial changes in distribution and penetration topical agent, dimethyl sulfoxide (DMSO) containing ketoprofen, using excised mouse skins. was performed 6 h after drug application to skin compared with results obtained Franz cell diffusion test, standard vitro absorption test. reflection showed that...
In vivo imaging methods to trace topical drugs within the skin are in high demand with recent advances transdermal drug delivery technology. With and chemical identification capabilities, terahertz (THz) spectroscopy can be a good modality for visualizing quantifying delivery. this study, we evaluated feasibility of THz reflection tomographic distribution penetration agent, ketoprofen dissolved DMSO, using ex mouse skins. skins demonstrated greater contrast between drug-applied sites...
The expression of the placental growth factor (PGF) in cancer cells and tumor microenvironment can contribute to induction angiogenesis, supporting cell metabolism by ensuring an adequate blood supply. Angiogenesis is a key component as it facilitates delivery nutrients oxygen rapidly growing cells. PGF recognized novel target for anti-cancer treatment due its ability overcome resistance existing angiogenesis inhibitors impact on microenvironment. We aimed integrate bioinformatics evidence...
Abstract Background We aimed to evaluate the feasibility of upper thigh level as a landmark measure muscle area for sarcopenia assessment on computed tomography (CT). Methods In 116 healthy subjects who performed CT scans covering from mid-abdomen feet, skeletal in at inferior tip ischial tuberosity (SMA UT ), mid-thigh MT and L3 endplate ) were measured by two independent readers. Pearson correlation coefficients between SMA , calculated. Inter-reader agreement readers evaluated using...
This article reports the results of online survey on Japanese-language educators’ beliefs and experiences concerning their profession that we conducted in fall 2018. A total 355 teachers North America responded to survey. The responses were analyzed quantitatively qualitatively. Quantitative data suggest respondents almost unanimously agreed importance global translingual/transcultural competence as a crucial goal for JFL education. However, items legitimacy language varieties (e.g.,...
The reliability of size measurements liver metastases from neuroendocrine tumors (NETs) on contrast-enhanced computed tomography (CT) phases made by different readers may be hampered due to transient, variable rim enhancement in arterial phase (AP) or portal venous (PVP) images. We aimed assess the tumor pre- and post-contrast scans.The study coordinator selected target lesions according Response Evaluation Criteria Solid Tumors 1.1 guidelines 44 consecutive patients with pathologically...
High-intensity focused ultrasound (HIFU) is an emerging technique for noninvasive ablative treatment. However, HIFU has rarely been performed the treatment of soft-tissue tumors. Thus, we aimed to assess feasibility and safety performing extracorporeal tumor. The response was assessed using functional magnetic resonance imaging (MRI) techniques. In rabbit VX2 intramuscular tumor model, device (YDME FEP-BY02) by varying electric power from 50 400 W, with other parameters being fixed. beam...
This study compares older adult learning in Korean and Japanese sample populations, paying special attention to after age 70. Surveys with nearly identical questionnaires were conducted the Bundang Senior Welfare Center Korea (N = 549, mean 73.6 years) at Osaka Prefecture College Japan 1,491, 787, 67.4, 69.5 years). The main results are as follows: (a) terms of needs, selected ratios topics “life review” “communication other seniors” increased respondents from their 60s 70s both countries;...
This study is one of the first to use validated screening measures examine rates self-reported mental health and interpersonal problems following deployment military personnel (MMHP). Research has examined impact on finding 10.2% 29.0% screen positive for at least problem. However, little known about impacts among MMHP. Utilizing data collected three twelve months post-deployment from a sample 759 Air Force MMHP, this screens psychological or problems, subsequent confirmation by medical...
디지털 환경에서 학습자가 주도적으로 가치로운 삶을 살아가기 위해 기술을 올바르게 이해하고 사용하여 정보를 탐색하고 활용하며 비판적으로 분석, 평가하여 소통하고 창조하는 역량인 디지털리터러시는 코로나19로 인한 팬데믹 후로 급격하게 그 필요성이 증대되어 사회 전반에서 기능을 하고 있다. 그러나 최근까지 디지털리터러시에 초점은 둔 다양한 연구는 이루어지지 않고 있기에 디지털리터러시 연구의 동향을 지난 10년간의 연구 4차 산업혁명의 기점이 되는 2016년을 기점으로 전기와 후기로 나누어 분석하여 살펴보았다.<BR> 양적 변화와 핵심 키워드, 연결중심성과 클러스터 맵의 변화를 파악하기 위하여 본 키워드 네트워크 분석을 실시하였으며 결과 첫째, 2011-2020까지 관한 변화가 전기 5년(2011년-2016년) 보다 후기 5년(2016년-2020년)간의 연구가 약 3.5배 정도 증가함을 파악하였다.<BR> 둘째, 디지털리터러시의 맵 분석 연결중심성이 가장 높은 키워드는 ‘교육’,...
Abstract Background Long-term acute care hospitals (LTACHs) for chronically, critically ill patients with high utilization of central lines and risk morbidity from line-associated bloodstream infections (CLABSIs). Our 38-bed LTACH noted a substantial increase in the incidence CLABSIs (as defined by National Healthcare Safety Network) between fiscal year (FY) 2016 FY 2018 (Figure 1). Detailed case review identified large number which were clinically consistent blood culture contaminants...
Abstract. The Republic of Azerbaijan has suffered from low agricultural productivity caused by soil salinization and erosion, limited insufficient data are available for economic political reasons. In this study, elemental composition heavy metal levels were assessed comparing the results XRF ICP-OES analyses first time.
