1. Lacrimal Diversion Devices (Sinopsys Lacrimal Stent): Sharing our Experience with Patients with Chronic Rhinosinusitis without Polyposis
Abstract Introduction Chronic rhinosinusitis (CRS) is a highly prevalent pathology in our society. Due to the prevalence of this condition and to the persisting symptoms despite an appropriate medical treatment, surgical techniques are often required. Lately, minimal invasive techniques have been described, such as lacrimal diversion devices (LDDs). This te

2. Development of a new model of actinic enteritis in rats using a cobalt-60 open source and a protection device as a collimator
Abstract Purpose: To describe a new model of actinic enteritis that does not use radiotherapy machines. Methods: Sixteen Wistar rats were divided into four groups, consisting of four animals each: control (group A), two weeks after irradiation (group B), five weeks after irradiation (group C) and eight weeks after irradiation (group D). Animals were given

3. Transanal Minimally Invasive Surgery (TAMIS) to Treat Vesicorectal Fistula: A New Approach
ABSTRACT Purpose: Vesicorectal fistula is one of the most devastating postoperative complications after radical prostatectomy. Definitive treatment is difficult due to morbidity and recurrence. Despite many options, there is not an unanimous accepted approach. This article aimed to report a new minimally invasive approach as an option to reconstructive surg

4. Laparoendoscopic Single-site Repair of Retrocaval Ureter Without any Special Devices
INTRODUCTIONThe retrocaval ureter is a rare congenital anomaly. The extrinsic compression may be responsible for obstruction and pain symptoms. The laparoscopic approach has been used with good results and less morbidity than the open surgery. Herein we describe a case of retrocaval ureter treated with LESS. To our knowledge, this represents the second such

5. Desenvolvimento de processo microfluídico para incorporação de DNA em lipossomas catiônicos destinados a terapia e vacinação gênica = : Development of microfluidic process for DNA incorporation into cationic liposomes for gene therapy and vaccination / Development of microfluidic process for DNA incorporation into cationic liposomes for gene therapy and vaccination
This research aimed at the technological development of microfluidic process for nonviral carriers production based on the electrostatic complexation between cationic liposomes (CL) and plasmidal DNA (pDNA) for gene and vaccine therapy applications. The development of this process was compared to the conventional bulk process, in which the solutions are mixe

6. Estudo da viabilidade para fabricação de fibra óptica polimérica (FOP) por extrusão vertical / Study of the feasibility on manufacturing polymeric optical fiber (POF) by vertical extrusion
Polymeric optical fibers (POF) presents some advantages compared to the glass optical fibers as flexibility, higher numerical aperture (NA), ease in handling and connecting due to their larger diameter and lower cost manufacturing and installation. However, due to their larger transmission losses compared to the main applications of glass fibers, POF are lim

7. Arquitetura amplificada: incorporação de dispositivos tecnológicos digitais à arquitetura
This dissertation presents a study about the incorporation of digital devices into architecture, focusing on experiences that, through the use of electronically mediated interactions, can enrich the relation between human beings and architectural space. Until a few decades ago, these devices were relatively disconnected from architecture, but recently there

8. Ultrafast electrooptical switching and regenerative conversion using semiconductor optical amplifiers / Chaveamento eletro-optico ultrarrapido e conversão regenerativa utilizando amplificadores opticos a semicondutor
Electrooptical switches, optical regenerators, and wavelength converters are relevant devices for the operation of future optical networks. In this work, measurements and simulations of an electrooptical switching time reduction technique based on multipulse current injection in semiconductor optical ampli.ers (SOA) are presented. Using the simulation result

10. Terapia antiangiogênica de tumores utilizando células produtoras de endostatina encapsuladas em dispositivos de imunoisolamento / ANTIANGIOGENIC THERAPY USING ENDOSTATIN PRODUCER CELLS ENCAPSULATED IN IMMUNOISOLATION DEVICES.
Endostatin is a specific inhibitor of endothelial cell proliferation, migration and a potent angiogenesis inhibitor. It has been shown that continuous administration of endostatin is more effective in tumor suppression than the same dose administered s.c. daily. Achieving concentration of endostatin to combat tumor growth is complicated by the short life of

12. Contribuições para melhoria do desempenho e viabilidade de fabricação de scanners indutivos / Contributions to improve the performance, and the manufacture viability of inductive scanners
Scanners are devices that deftects a light beam and converts a spot light in a well controlled amplitude and frequency scan line. Several applications uses the generated pattem to code or decode data, common examples ar,e barcode readers, and laser printers. A light beam can be deftected by different means. In this work, the scanner deftects the light by ref
