1. Assessment of retinal nerve fiber thickness and optic nerve head blood flow in female patients diagnosed with fibromyalgia syndrome
RESUMO Objetivo: Numerosos estudos de neuroimagem e oftalmologia sugerem o acometimento do nervo óptico na síndrome de fibromialgia. Para esclarecer a etiopatogenia da síndrome de fibromialgia, comparamos a área de fluxo sanguíneo da cabeça do nervo óptico e a espessura da camada de fibras nervosas da retina entre pacientes e o grupo controle, e exam

2. A influência do oxido nítrico na fisiopatologia da neuropatia glaucomatosa
Resumo O oxido nitrico (NO) é um fator relaxante derivado do endotélio e um potente vasodilatador que impacta em vários sistemas em todo o corpo. Estudos comprovam que o fluxo sanguíneo ocular basal é regulado pelo NO, sendo um importante regulador da homeostase, especialmente dentro dos tecidos uveais. A disfunção da produção de NO seria associado

3. Blood flow velocity in monocular retinoblastoma assessed by color doppler
OBJECTIVE: To analyze the flow of retrobulbar vessels in retinoblastoma by color Doppler imaging. METHODS: A prospective study of monocular retinoblastoma treated by enucleation between 2010 and 2014. The examination comprised fundoscopy, magnetic resonance imaging, ultrasonography and color Doppler imaging. The peak blood velocities in the central retinal

4. Avaliação da atividade neuroprotetora da Parawixina 11 isolada da peçonha da aranha Parawixia bistriata (Araneae, Araneidae), em ratos Wistar submetidos a um modelo de glaucoma agudo / Neuroprotective activity analysis of Parawixin 11, isolated from Parawixia bistriata (Araneae, Araneidae) spider venom, in Wistar rats submitted to an model of acute glaucoma
Glaucoma is defined as a typical optic neuropathy characterized by ganglion cells loss and consequent optic nerve damage, resulting in a gradual reduction of the visual field and eventual blindness. In regard to compounds present in spider venoms, they represent an interesting source of bioactive molecules and the study about the possible neuroprotective eff

5. Uma avaliação sobre características espaço-temporais baseadas em invariantes de cor para reconhecimento de ações
Local spatiotemporal feature has been proved to be a powerful tool to represent latent patterns of moving objects in video scenes. In particular, recognition of human actions has been the principal focus for various growing applications, including video indexing, content-based video retrieval, video summarization, filtering of unwanted content, rating of mov

6. Projeto de um sistema de desvio de obstáculos para robôs móveis baseado em computação reconfigurável / Design of an obstacle avoidance system for mobile robots based on reconfigurable computing
The area of mobile robotics is undergoing a tremendous expansion, but one of the obstacles to be dealt with is the development of embedded computational systems that combine low power consumption and high performance. Reconfigurable computing has the potential to meet these requirements. This project is an evaluation of the complexities of fully exploiting t

7. Sistema canabinóide e seu possível papel em processos de neuroproteção e plasticidade: estudos in vivo e in vitro. / The cannabinoid system and its possible role in neuroprotection and plasticity processes: in vivo and in vitro studies.
The cannabinoid system (CS) seems to have a role in several neurobiological processes, including neuroprotection and neuronal plasticity. The aims of this study were to verify the effects of unilateral retinal ablation on the expression of cannabinoid receptor CB1 and other structural proteins in the optic tectum of chick brain by immunohistochemistry, immun

8. Avaliação da aplicação de acido folico em tratamento aerobio de aguas residuarias. / Evaluation of application of folic acid in aerobic wastewater treatment .
They are deficiency of vitamins in sludge of biological wastewater treatment, especially the folic acid, that acts as micronutrient for certain bacteria and stimulating its growth. This work evaluated the effect of different concentrations of folic acid on the sludge in normal physiologic conditions and in endogenous respiration. The system was carried out b

9. Segmentação fuzzy de imagens e vídeos
Image segmentation is the process of subdiving an image into constituent regions or objects that have similar features. In video segmentation, more than subdividing the frames in object that have similar features, there is a consistency requirement among segmentations of successive frames of the video. Fuzzy segmentation is a region growing technique that as

10. Evaluation of public politics: the itinerary of the exits of the project correction of flow in Toledo (PR) / Avaliação de politica publica : o itinerario dos egressos do projeto correção de fluxo de Toledo (PR)
The present paper aims to establish the itinerary (relating to its educational development and to its insertion in the labor market and in its social project) of egressing students in the Flow Correction Project (FCP), during 1997 and 1998. For this purpose, six central questions have been established: 1) the FCP provides the necessary conditions so that the

11. Use of two-dimensional correlation spectroscopy and construction and evaluation of a near-infrared spectropolarimeter / Uso da espectroscopia de correlação bidimensional (2D) e construção e avaliação de um espectropolarímetro para a região do infravermelho próximo (NIR)
The two-dimensional correlation spectroscopy was used in this work as a tool for spectral variable selection in the near-infrared (NIR) region aiming the determination of the following quality parameters of gasoline: ethanol content, MON (Motor Octane Number) and RON (Research Octane Number). To achieve this objective, it was developed a flow system to autom

Schistosomiasis mansoni is an infectious disease caused by a worm (Schistosoma mansoni), which has the human as one of the definitive hosts in its evolutive course. In more advanced stages, massive embolization by eggs layed in the portal venous sistems by adult forms of the parasite to the hepatic parenchima occurs; this leads to inflammatory reactions in t
