The objective of this review of the literature is to detail the technical challenges associated with D3 lymphadenectomy for right-sided colon cancer, and to examine the terms used throughout the medical literature to describe the central lymph nodes. We conducted a review of the relevant English language literature, using the electronic search of the PubMed/Medline and Google Scholar databases....

BACKGROUND Nonocclusive mesenteric ischemia (NOMI) is a mesenteric arterial spasm and intestinal ischemia. This disease is a highly lethal disease because diagnosis and decision of appropriate treatments are often difficult. Operations cannot resolve the spasms and may worsen the situation. However, the safety and effectiveness of catheterization for NOMI with aortic dissection (AD) have not ye...

in this paper the design of a biped robot actuated with shape memory alloy (sma) springs with minimum degrees of freedom is presented. sma springs are a class of smart materials that are known for their high power to mass and volume ratios. it was shown that utilizing spring type of smas have many advantages as large deformation, smooth motion, silent and clean movement compared to ordinary typ...

One important challenge of microsystems design is the implementation of miniaturized actuation principles efficient at the micro-scale. Shape Memory Alloys have early on been considered as a potential solution to this problem as these materials offer attractive properties like a high-power to weight ratio, large deformation and the capability to be processed at the microscale. This paper review...

Results: is performed patient placed in a supine, split-leg position and carefully secured operative table, surgeon on foot between legs, an assistant at each...

PURPOSE We report the clinical outcomes of patients with spontaneous isolated dissection of the superior mesenteric artery (SIDSMA) who were treated conservatively. MATERIALS AND METHODS A retrospective review was performed in 14 patients from 2006 to 2016 with SIDSMA. Their clinical features and computed tomographic angiography (CTA) characteristics, treatment methods, and clinical outcomes ...

In this paper, we propose an original formalism inspired by Markov Decision Process in order to represent homogeneously actions and direct interactions between agents. Thanks to the introduction of individual rewards characterising the problem to be solved, this formalism is a first step towards the automatic computation of policies and use of available interactions. A simple problem of distrib...
