OBJECTIVE Chest wall resection and reconstruction is a demanding operation involving a dedicated team. It can be performed with minimal mortality with excellent cosmetic and functional results using various substitutes. However, reconstructing the lower costal margin with diaphragmatic resection is a challenging prospect needing special techniques. METHODS We describe a technique of reconstru...

Laparoscopic multi-visceral resection in patients with T4 colorectal cancer remains controversial. A 73-year-old man was admitted to the hospital for rectosigmoid cancer directly invading the urinary bladder trigone without distant metastasis. We successfully performed complete resection by laparoscopic anterior pelvic exenteration while preserving the anus. After laparoscopic mobilization of t...

Abstract The aim of this research is to review the literature for influence thickness and shape cervicalmargins on strength posterior monolithic zirconia crowns. Studies assess fracture resistance crowns with different types cervical margins, published from 2014 2020, were searched using electronic database PubMed Google Scholar following keywords: “monolithic zirconia,” “translucent,” “shoulde...

Background. Gastric gastrointestinal stromal tumors (GISTs) that are predominantly endophytic or in anatomically complex locations pose a challenge for laparoscopic wedge resection; however, endoscopic resection can be associated with a positive deep margin given the fourth-layer origin of the tumors. Methods. Patients at two tertiary care academic medical centers with gastric GISTs in difficul...

BACKGROUND In this study, we aimed to establish the rabbit VX2 limb tumor model, and then prepare a "necrotic zone" as a safe margin by volumetric modulated arc therapy and simultaneous integrated boost (VMAT-SIB) technique applied in the areas where the tumor is located adjacent to the bone (GTVboost area). MATERIAL AND METHODS Rabbits in the control group (n=10) were not treated, while thos...

Introduction. When using the double interval slide technique for arthroscopic repair of chronic large or massive rotator cuff tears, the posterior interval release is directed toward the scapular spine until the fat pad that protects the suprascapular nerve is reached. Injury to the suprascapular nerve can occur due to the nerve's proximity to the operative field. This study aimed to identify s...

In this brief, the margin of stability of two-dimensional (2D) discrete systems is considered. A new method to compute the stability margin of 2-D continuous systems is provided. Illustrative examples are also included.

Abstract: In this project we will explore the properties of stochastic matrices in both the real and the finite fields. We first explore what properties 2  2 stochastic matrices in the real field have and then exam if they hold in the finite fields. We will prove how, given the conditions of a finite field, properties hold or fail to hold. We will extend our scope to 3  3 stochastic matrices ...
