1. A novel labeling modality of intra-abdominal lesions with Magseed magnetic marker and extirpation by Sentimag probe navigation
SUMMARY OBJECTIVE: This study aimed to evaluate our experience with the use of Magseed, the magnetic metallic marker, as a localization technique followed by Sentimag probe detection in patients with solitary intra-abdominal local metastases with subsequent resection of the lesions. METHODS: Five patients underwent resection after the lesion was marked wit

2. Cone beam computed tomography study of apical root resorption induced by Herbst appliance
Objective This study evaluated the frequency of root resorption during the orthodontic treatment with Herbst appliance by Cone Beam Computed Tomography (CBCT). Material and Methods The sample comprised 23 patients (11 men, 12 women; mean ages 15.76±1.75 years) with Class II division 1 malocclusion, treated with Herbst appliance. CBCT was obtained before

3. Comparação entre o planejamento pré-operatório e a navegação intraoperatória na osteotomia valgizante da tíbia: análise do eixo mecânico e do tamanho das cunhas de adição / Comparison of preoperative planning and intraoperative navigation surgery in tibial osteotomies: analysis of the mechanical axis and the size of the wedges of addition
O resultado clínico a longo prazo das osteotomias valgizantes da tíbia depende da obtenção do adequado alinhamento do eixo mecânico pelo procedimento cirúrgico. Essa correção do eixo mecânico é obtida pela adição ou subtração de cunhas ósseas. O tamanho das cunhas pode ser planejado pré-operatoriamente ou determinado durante a cirurgia utiliz

4. Determinação de órbita e manobras utilizando GPS e motor com baixo empuxo / Orbit determination and autonomous maneuver using GPS and low thrust
The Global Positioning System (GPS) is a satellite navigation system that allows the users to determine 3D positioning and the time with high precision. Its main purposes are: aid to radionavigation in three dimensions with high precision positioning, navigation in real time, global coverage and quick acquisition of data sent by the GPS satellites. In this w

5. Método de otimização topológica aplicado ao projeto de sonotrodos para transdutores piezelétricos. / Topology optimization method applied to the design of transducers sonotrodos piezoelectric.
This work aims at the development of a method based on Topology Optimization to design a mechanical structure, called sonotrode, which is a device usually connected to a high power piezoelectric transducer (mechanical device capable of converting electric energy into mechanical displacement or vice-versa). A sonotrode transmits mechanical vibrations of a pie

6. Navegação através de um sistema integrado GPS/INS baseado em IMU não-giroscópica / Integrated GPS/INS navigation system based on gyroscope free IMU
The present work has the objective of analyzing the performance of a low cost strapdown inertial navigation system (INS), based on a gyroscope free inertial measurement unit (IMU) that only uses multiples accelerometers and is aided by a GPS receptor data. The availability of low cost, size and weight accelerometers with medium performance and more robustnes

7. Computer-navigated Iliosacral Screw Insertion Reduces Malposition Rate and Radiation Exposure
Insertion of percutaneous iliosacral screws with fluoroscopic guidance is associated with a relatively high screw malposition rate and long radiation exposure. We asked whether radiation exposure was reduced and screw position improved in patients having percutaneous iliosacral screw insertion using computer-assisted navigation compared with patients having

8. Six Sigma Analysis of Minimally Invasive Acetabular Arthroplasty: A Preliminary Investigation
Minimally invasive techniques in THA may increase the difficulty of acetabular component insertion relative to the optimized position. We sought to determine the ability of eight surgeons to position an acetabular component placed using an anterior-lateral minimally invasive surgical (MIS) approach with conventional instruments or computer navigation using a

9. Human Disease Genes and Their Cloned Mouse Orthologs: Exploration of the FANTOM2 cDNA Sequence Data Set
The FANTOM2 cDNA sequence data set is an excellent model to demonstrate the power of large-scale cDNA sequencing, with the goal of providing a full-length transcript sequence for each mouse gene. This data set enhances the use of the mouse as a model for human disease. Here we identify mouse cDNA sequences in the FANTOM2 data set for a set of 67 human di
