1. Cochlear Implantation and Single-sided Deafness: A Systematic Review of the Literature
Introduction Current data show that binaural hearing is superior to unilateral hearing, specifically in the understanding of speech in noisy environments. Furthermore, unilateral hearing reduce oné s ability to localize sound. Objectives This study provides a systematic review of recent studies to evaluate the outcomes of cochlear implantation in patien

2. Efeitos da restrição proteica gestacional em hipocampo de ratos machos adultos : avaliação da estrutura dendrítica tridimensional, do comportamento e de componentes neuroquímicos = Effects of gestational protein restriction in hippocampus of adult male rats / Effects of gestational protein restriction in hippocampus of adult male rats : evaluation of three-dimensional dendritic structure of hippocampal neurons, behavior and neurochemical components
Studies have demonstrated that maternal nutritional restriction during pregnancy or in early postnatal life results in hippocampus cognitive impairment and structural abnormalities in the 16-wk-old offspring. In an attempt to analyze whether gestational protein restriction might induce learning and memory impairment associated with structural changes in the

3. Molecular mechanisms of RET receptor-mediated oncogenesis in multiple endocrine neoplasia 2
Multiple endocrine neoplasia type 2 is an inherited cancer syndrome characterized by tumors of thyroid and adrenal tissues. Germline mutations of the REarranged during Transfection (RET) proto-oncogene, leading to its unregulated activation, are the underlying cause of this disease. Multiple endocrine neoplasia type 2 has been a model in clinical cancer gene

4. Inclusão de MRI e informação multigrid a priori para inferência bayesiana de fontes de M/EEG / MRI image and multigrid a priori information for bayesian M/EEG source localization
Functional Neuroimaging has evolved in the last few decades with the introduction of techniques such as Positron Emission Tomography or PET and Functional Magnetic Ressonance Image or fMRI [Belliveau et al., 1991]. These allow observing brain activity with a resolution of a few millimeters and, due to the nature of the signal, a time resolution of the order

5. Traumatic brain injury patients: does frontal brain lesion influence basic emotion recognition?
Adequate emotion recognition is relevant to individuals' interpersonal communication. Patients with frontal traumatic brain injury (TBI) exhibit a lower response to facial emotional stimuli, influencing social interactions. In this sense, the main goal of the current study was to assess the ability of TBI patients in recognizing basic emotions. Photographs o

6. Hardware/Software codesign of particle filter for real time localization of mobile robots / Co-projeto de hardware/software do filtro de partículas para localização em tempo real de robôs móveis
Sophisticated techniques for estimation of models based on simulation, particle filters or Sequential Monte Carlo Methods, were recently used to solve many difficult problems in the field of mobile robotics. However, the success of particle filters was limited to the computation of parameters in low dimensionality spaces. The current research efforts in mobi

7. Estudo dos efeitos da terapia fotodinâmica na progressão tumoral e em modelos celulares tridimensionais / Study of the effects of photodynamic therapy on tumor progression and in three-dimensional cellular models.
Melanoma is the type of skin cancer with poor prognosis due to its high probability of suffering metastases. Currently there are few effective treatments for the this, and the survival of patients with metastases is very low, around 8 months, with cure rates of these conditions do not exceed 1%. Photodynamic therapy (PDT) is a therapeutic modality selective

8. Comportamiento del tiempo de duración, la frecuencia de los cortocircuitos y la conductividad eléctrica durante el reencendido del arco en la soldadura SMAW (AC) con electrodos E6013
The objective of this work is the valuation of the behavior of short-circuits frequency and duration time and electrical conductivity on arc reigniting in SMAW (Shielded Metal Arc Welding) process with alternate current and E6013 electrodes. The non parametric statistic analysis realize a robust data processing, minimizing the outliers influence and mistakes

9. EstatÃstica de contagem de carga e efeitos de interferÃncia em sistemas mesoscÃpicos
In this thesis we presented a detailed study about full counting statistics of transmitted charge and accumulated phase and the quantum interference corrections to the average conductance and the average shot-noise power in non-ideal ballistic chaotic cavities. In the theoretical analysis of this mesoscopic system, we obtained analytical expressions for the

11. Expressão e reposição estrogenica e androgenica no lobo ventral da prostata de camundongos diabeticos (NOD) frente a terapia insulinica / Androgen and estrogen replacement and expression in the ventral lobe of the prostate of non-obese diabetic mice (NOD) following insulin therapy
Diabetes adversely affects prostate morphology and function through alterations in the hypothalamic-hypophyseal-gonadal axis. Thus, the aims of this study were to characterize morphological, proliferative and immunological features of the prostate of diabetic mice after long term glycemic control and hormonal replacement, and as well as to relate these param

12. Linkage disequilibrium, genetic association mapping and gene localization in crop plants
DNA-based molecular markers have been extensively utilized for a variety of studies in both plant and animal systems. One of the major uses of these markers is the construction of genome-wide molecular maps and the genetic analysis of simple and complex traits. However, these studies are generally based on linkage analysis in mapping populations, thus placin
