Abstract This study aimed to develop a versatile automatic segmentation model of bladder cancer (BC) on MRI using convolutional neural network and investigate the robustness radiomics features automatically extracted from apparent diffusion coefficient (ADC) maps. two-center retrospective used multi-vendor MR units included 170 patients with BC, whom 140 were assigned training datasets for modified U-net five-fold cross-validation 30 test assessment performance reproducibility features. For...
Background Residual symptoms after pulmonary endarterectomy ( PEA ) remain as the clinical issues to be solved. Additional balloon angioplasty BPA showed its efficacy with in a case series, although long‐term spontaneous recovery of exercise ability was also reported. However, no studies have validated additional by directly comparing and without . The aim this study retrospectively evaluate sequential hybrid therapy for chronic thromboembolic hypertension Methods Results Among 44 patients...
This study evaluated the impact of aspirin on biochemical recurrence (BCR) rate following robot-assisted radical prostatectomy (RARP) in patients. A database search identified patients who underwent RARP for pT2-3N0M0 disease at any 25 centers between 2011 and 2022, categorized into (n = 350) control groups 5857). Adjustment by 1:1 propensity score matching (PSM) Mahalanobis distance (MDM) created 350 matched pairs. The effect BCR was analysis BCR-free survival. After PSM MDM, 3-year...
<h2>Abstract</h2><h3>Background</h3> The management of non-operable chronic thromboembolic pulmonary hypertension (CTEPH) has evolved with the availability balloon angioplasty (BPA) and vasodilators. We launched BPA program in 2011. aim was to analyze survival treatment efficacy our CTEPH modern era. <h3>Methods results</h3> retrospectively reviewed data from 143 consecutive patients diagnosed January 2011 (i.e. after BPA) December 2019. Of forty-one who underwent endarterectomy (PEA), 25...
Abstract This study aimed to assess the effects of thienopyridine-class antiplatelet agents (including ticlopidine, clopidogrel, and prasugrel) on bleeding complications in patients who underwent robot-assisted radical prostatectomy. cohort used a database for prostatectomy at 23 tertiary centers nationwide between 2011 2022. Patients received thienopyridines (thienopyridine group) were compared with those aspirin monotherapy (aspirin group). The primary outcome was incidence complications....
In this paper, we describe the development of a human-sized remotely operated vehicle (ROV) with dual-arm. The developed ROV was designed to perform biological researches, geological researches and archaeological explorations in Lake Biwa, biggest lake Japan. This has two distinguishing characteristics: one is dual-manipulator system other an attitude control system. size manipulators related human arm so that can do work divers usually using arms. capable keeping horizontal plane, purposely...
As described in this paper, we propose an attitude control system for underwater vehicle/manipulator systems (UVMSs) based on of the position center buoyancy with respect to gravity. Control is accomplished using movable float blocks. The useful pitch angle UVMSs enhance their performance and improve efficiency operations. A UVMS that has two 5-degree-of-freedom (DOF) manipulators was developed verify effectiveness proposed system. This paper presents a numerical study some experimental...
This paper reports the development of a robotic inspection system using mechanical contact mechanism that enhances positioning stability small and lightweight underwater robot to take clear images targets work with manipulators for inspections under external disturbances. As described in this paper, first we perform two‐dimensional numerical analysis based on force moment acting an mechanism. Second, experimentally investigate friction coefficients several soft high materials points...
Background We evaluated the importance of high-density lipoprotein (HDL) functionality for target-lesion revascularization in patients treated with coronary stents using a rapid cell-free assay system to evaluate functional capacity HDL accept additional cholesterol (cholesterol-uptake capacity; CUC). Methods and Results From an optical coherence tomography (OCT) registry stents, 207 were enrolled their was functionally by measuring CUC. Follow-up OCT performed (median duration, 24.5 months...
Since September 1992, 63 patients with symptomatic benign prostatic hyperplasia (BPH) have been treated transurethral microwave thermotherapy (TUMT) using the Prostatron device. The International Prostate Symptom Score (l‐PSS) and quality of life (QOL) score were used to evaluate subjective symptoms. mean l‐PSS (total, irritative obstructive scores) QOL scores had decreased by 40, 38, 45 40%, respectively, at 12 months (p < 0.0001). While peak flow rate increased 72% 0.001). clinical...
This paper proposes a method of, given multilevel image called reference in which an arbitrary shape S lies and another input one rotated parallel translated from lies, computing the angle of rotation quantity translation. applies modified version Hough transform proposed by O'Gorman Clowes (1976) to images, computes uniquely. Moreover, this needs no extracting feature points, is applicable low quality images.
This paper presents a new design approach for the soft-switching resonant converter with satisfying multiple conditions. As an example, FM controlled class-E is designed. By applying inverter at part, works high efficiency frequencies. The has, however, problems, which are peak value of switch voltage and difficulty zero-voltage switching continuation against load variations. Additionally, there restriction on transformer voltage. In proposed approach, we can find proper component values,...
This paper presents ship hull inspection using a small underwater robot with mechanical contact mechanism. We propose approach in order to conduct inspection, and develop mechanism, hand-eye vision system, stereo camera system. The proposed mechanism enhances the position orientation keeping performance of robots. developed system provide fine detailed information for inspection. In this paper, we numerically analyze fundamental experiments test tank. Additionally, inspect ship's port as...
<b>Background</b> Most free flap reconstruction complications involve vascular compromise. Evaluation of anatomy provides considerable information that can potentially minimize these complications. Previous reports have shown contrast-enhanced computed tomography is effective for understanding three-dimensional arterial anatomy. However, most result from venous thromboses, making imaging highly desirable. <b>Methods</b> The phase-lag angiography (pl-CTA) technique involves 64-channel...
The existence of microvasculopathy in patients with chronic thromboembolic pulmonary hypertension has been suggested. Recently, dual‐energy computed tomography used to produce a sensitive iodine distribution map lung fields indicate according poor subpleural perfusion. Our aim was evaluate the impact on pathophysiology hypertension. According extent perfusion, ninety‐three interventional treatment‐naïve were divided into poorly perfused ( n = 49) or normally group 44). We assessed...
