We determined the impact of extent regional lymphadenectomy on survival in patients with urothelial carcinoma upper urinary tract.Between January 1989 and 2006, 169 nonmetastatic tract underwent curative surgery. previously reported primary sites nodal metastases tract. Nodal where incidence was 30% or more were considered lymph nodes. When all resected, this complete lymphadenectomy. Regional without removal incomplete retrospectively analyzed influence patient survival.A total 45 (26.6%)...
Objectives: The benefit of lymphadenectomy (LND) in patients with urothelial carcinoma the upper urinary tract (UCUUT) has remained controversial. aim this study was to examine influence LND template and total number lymph nodes (LN) when increasing undergoing complete dissection regional (CompLND). Methods: A 109 UCUUT clinically negative underwent nephroureterectomy concomitant at our center. Patients' survival examined according type removed LN. Univariate analysis performed find cut‐off...
This study proposes a cleaning machine using multistage planetary gear mechanism to remove accumulated grease from kitchen ducts with various geometries, including circular and square configurations. The contributions of this encompass the design machine, that can scrub off at four corners near central regions inner wall once—a task has been difficult in past. Furthermore, velocity simulations estimated relative brushes duct wall. Additionally, results experiment conducted proposed were...
This paper proposes a robot that combines hyper-extension unit at the front with an earthworm-type rear, designed to inspect long, narrow, and complex pipelines. In conventional in-pipe inspection robots simple designs, there was no mechanism for effectively exert traction propulsion while optimizing speed according required force. Therefore, this describes development of front, which achieves elongation rate approximately 300% even low expansion rates, rear. The developed can operate in two...

A 100 kW OTEC pilot plant was constructed for demonstration purposes in the Republic of Nauru and began, October 1981, to send electricity real power system. The main points plan, design technical considerations are introduced as well operation results up date. This has proved validity electrical mechanical design, underwater pipeline laying method field ocean-civil engineering.
The cleaning of residential ventilation ducts is necessary to prevent damage health. However, since are usually thin and curved, them difficult. It also difficult obtain thrust within the duct using a wheel or snake type robot because it hard an appropriate reaction force in deformed pipe. Therefore, pipe must be gripped stably even if flexible so that can generated run through In this paper, we modeled uses peristaltic motion running with inner diameter 50 mm. Then, validity model was...
In this study, an earthworm-type electrical wire installation assistance robot is proposed using pneumatic artificial muscles. This letter contributes to describing the design and experiments regarding a that can safely automatically install wires in complex conduits within limited deadline. we aim develop assist of conduits. study development for results from field experiments. Based on previous studies, long narrow has not been developed. applicability presented. The showed at average...
Thirty rabies virus isolates from cows and vampire bats different regions of São Paulo State, Southeastern Brazil three vaccines were studied genetically. The analysis was based on direct sequencing PCR-amplified products 600 nucleotides coding for the amino terminus nucleoprotein gene. sequences checked to verify their genealogical evolutionary relationships possible implication health programmes. Statistical data indicated that there no significant genetic differences between samples...

Abstract: The treatment for bilateral testicular tumors is associated with infertility and hypogonadism. We carried out testis‐preserving therapy three patients synchronous seminoma. Our protocol of testis preservation consisted unilateral orchiectomy the larger tumor followed by courses chemotherapy a cisplatin, etoposide bleomycin regimen. All showed no recurrence 24, 82 months after treatment. serum testosterone level was maintained around lower limit normal range in all without androgen...
In this study, the authors comprehensively evaluated traveling performance of a flexible pipe inspection robot (PI-RO) that can actively output both propulsion and traction forces. Household pipes must be frequently inspected for cracks corrosion to ensure continuous provision water gas. As these are essential our everyday life, it is difficult suspend their usage long periods; hence, should conducted short durations. addition, inspecting entire pipelines using existing methods challenging...
This paper describes the design, experiments, and quantitative force comparison of a Pipe Inspection RObot named PI-RO II using enhanced linear antagonistic mechanism to amplify traction. study aims develop an inspection robot for long, narrow, complex pipes requiring large traction, propulsion, flexibility. Many types pipe soft pneumatic actuators were proposed in conventional studies, focusing on compatibility, high-power characteristics, In previous study, we allowing generate both high...
Biological organisms face multiple requirements to survive in their environments. This article describes a design method for multiobjective optimization construct bioinspired robot that performs multisprings-driven fast movements by exploiting several mechanical elements, such as springs, latches, and linkages. To control the duration required preparatory loading unloading, it is important this power-amplification system parameters of independent springs acting translational rotational...
