1. The neurology behind three wounded French artists during the great world war
Resumo Uma associação única une Guillaume Apollinaire, Blaise Cendrars e Louis Ferdinand Céline. Além de serem grandes expoentes da literatura francesa, todos eles foram feridos neurologicamente durante a Primeira Guerra Mundial. Apollinaire sofreu traumatismo cranioencefálico, Cendrars desenvolveu dor neuropática do membro fantasma e Céline apresent

2. Atypical odontalgia: pathophysiology, diagnosis and management
RESUMO JUSTIFICATIVA E OBJETIVOS: A odontalgia atípica, um subtipo da dor facial idiopática persistente, se caracteriza por dor contínua em um ou mais dentes, ou no alvéolo, após exodontia sem qualquer causa aparente e é um desafio para o dentista. O desconhecimento por parte do profissional pode levar a procedimentos odontológicos desnecessários e

3. PENSAR A ARTE NA ANÁLISE DE DISCURSO: UMA ANÁLISE N'O FANTASMA DA LIBERDADE
Resumo A fim de pensar o estatuto da arte a partir da Análise de Discurso (AD), este artigo empreende a teorização do regime estético das artes como Formação Discursiva Estética (FDE). Para exemplificar o funcionamento dessa FD em torno do questionamento das evidências e do estabelecimento do equívoco como modo mesmo de produção de sentidos, lanç

4. Mean scatterer space estimation from ultrasound signals combining singular spectral analysis and entropy
AbstractIntroduction: Ultrasound (US) is a nonionizing radiation capable of real time imaging at low cost. Its most attractive application is quantitative tissue characterization with the objective of differentiating normal tissues from diseased tissues. In this study, an automated method using singular spectrum analysis (SSA) to estimate the mean scatterer

5. Polysomnography Applied to Patients with Tinnitus: A Review
Abstract Introduction Tinnitus has been defined as an “auditory phantom perception,” meaning that tinnitus results from an abnormal activity within the nervous system, in the absence of any internal or external acoustic stimulation. About 10 to 15% of the adult population is affected by tinnitus, and a relevant percentage of tinnitus sufferers experien

6. Photoacoustic-based thermal image formation and optimization using an evolutionary genetic algorithm
Abstract Introduction For improved efficiency and security in heat application during hyperthermia, it is important to monitor tissue temperature during treatments. Photoacoustic (PA) pressure wave amplitude has a temperature dependence given by the Gruenesein parameter. Consequently, changes in PA signal amplitude carry information about temperature varia

8. Absorbed doses in salivary and thyroid glands from panoramic radiography and cone beam computed tomography
Abstract Introduction: Panoramic radiography and cone beam computed tomography (CBCT) are very important in the diagnosis of oral diseases, however patients are exposed to the risk of ionizing radiation. This paper describes our study aimed at comparing absorbed doses in the salivary glands and thyroid due to panoramic radiography and CBCT and estimating ra

9. Mirror therapy: A potential intervention for pain management
Summary The consequences of chronic pain and associated disabilities to the patient and to the health care system are well known. Medication is often the first treatment of choice for chronic pain, although side effects and high costs restrict long-term use. Inexpensive, safe and easy to self-administer non-pharmacological therapies, such as mirror therapy,

10. Ultrasonic method of microvibration detection: part II - additional processing method and applications
Abstract Introduction In the last 28 years, the scientific community has been using elastography to evaluate the mechanical properties of biological tissue. The aim of this work was the optimization of the UDmV method, presented in Part I of the series, by means of modifying the technique employed to generate the reference sine and cosine functions, used fo

11. Dosimetry in CBCT with Different Protocols: Emphasis on Small FOVs Including Exams for TMJ
Resumo O objetivo deste estudo foi estimar a dose absorvida em exames de tomografia computorizada de feixe cônico (TCFC) de acordo com diferentes parâmetros de exposição, tamanho e posição do campo de visão (FOV, do inglês field of view). Além disso, comparou-se a dose absorvida em uma única aquisição com FOV grande com aquela em duas aquisiçõe

12. Phantoms for diffusion-weighted imaging and diffusion tensor imaging quality control: a review and new perspectives
Abstract: Introduction Diffusion-weighted imaging (DWI) and diffusion tensor imaging (DTI) combine magnetic resonance imaging (MRI) techniques and diffusion measures. In DWI, the contrast is defined by microscopic motion of water protons. Nowadays, DWI has become important for early diagnostic of acute stroke. DTI images are calculated from DWI images acqui
