1. Surgical Removal of The Mechanical Valve Leaflet Dislocated into The Pulmonary Vein
ABSTRACT Accidental detachment of mechanical valve leaflet during implantation is a rare and potentially serious complication. When the lost leaflet cannot be found by direct visualisation, additional diagnostic procedures are necessary to detect it. Computer tomography is the best detection method, but the patient needs reoperation. We presented a patient i

5. Analysis of biodeterioration wood estate: use different techniques to obtain images
ABSTRACT This study was based on the current status of locomotive turntable of Provincial Railway Station in La Plata. It was inaugurated in 1910 and it was declared as architectural heritage in 2006. The locomotive turntable is 200 meters from this station and it is a structure that consists in wooden slats of Schinopsis sp. into metal framework. Currently,

6. Alternative approach of a Fibroepithelial polyp
ABSTRACT A 41-year-old male presented at Emergency Department (ED) with right flank pain associated with hematuria for 3 days. Patient had a previous history of nephrolithiasis. The physical examination and blood tests were normal. Urine analyses showed haematuria > 1.000.000/μL. After clinical evaluation, a computer tomography (CT) showed right ureteral di

7. Peri-implant assessment via cone beam computed tomography and digital periapical radiography: an ex vivo study
OBJECTIVES: This research evaluated detail registration in peri-implant bone using two different cone beam computer tomography systems and a digital periapical radiograph. METHODS: Three different image acquisition protocols were established for each cone beam computer tomography apparatus, and three clinical situations were simulated in an ex vivo fresh p

8. Treatment of patients with aortic atherosclerotic disease with paclitaxel-associated lipid nanoparticles
OBJECTIVE: The toxicity of anti-cancer chemotherapeutic agents can be reduced by associating these compounds, such as the anti-proliferative agent paclitaxel, with a cholesterol-rich nanoemulsion (LDE) that mimics the lipid composition of low-density lipoprotein (LDL). When injected into circulation, the LDE concentrates the carried drugs in neoplastic tiss

9. Parameter estimation of an artificial respiratory system under mechanical ventilation following a noisy regime
Abstract Introduction: This work concerns the assessment of a novel system for mechanical ventilation and a parameter estimation method in a bench test. The tested system was based on a commercial mechanical ventilator and a personal computer. A computational routine was developed do drive the mechanical ventilator and a parameter estimation method was util

10. Efficacy Analysis of a Script-based Guide for EVAR Execution: is it Possible to Reduce Patient Exposure to Contrast, Operative Time and Blood Loss even when Advanced Technologies are not Available?
ABSTRACT INTRODUCTION: Despite the patient and medical staff exposure to radiation in endovascular aneurysm repair, the benefits of this abdominal aortic aneurysm type of surgical management are justfied by minor recovery time and hospitalization, as well as an option for patients not elected to conventional open repair. In this minimally invasive surgical
