1. Analysis of the immunological biomarker profile during acute Zika virus infection reveals the overexpression of CXCL10, a chemokine linked to neuronal damage
BACKGROUND Infection with Zika virus (ZIKV) manifests in a broad spectrum of disease ranging from mild illness to severe neurological complications and little is known about Zika immunopathogenesis. OBJECTIVES To define the immunologic biomarkers that correlate with acute ZIKV infection. METHODS We characterized the levels of circulating cytokines, chemok

2. Influence of microbiome species in hard-to-heal wounds on disease severity and treatment duration
ABSTRACT BACKGROUND: Infections, mostly those associated with colonization of wound by different pathogenic microorganisms, are one of the most serious health complications during a medical treatment. Therefore, this study is focused on the isolation, characterization, and identification of microorganisms prevalent in superficial wounds of patients (n = 50

3. El enfoque de vulnerabilidad en los Sistemas de Información en Salud Ambiental: aplicación de la Metodología Diagnóstica del Riesgo de la Vivienda para la Salud (DRVS) en Belém, Brasil
Abstract This study is carried out within the Inter-American Network of Healthy Housing framework, supported by OPS / OMS, and it springs from the need to strengthen national and local systems of environmental health control and monitoring so as to identify social inequalities and to promote alternative forms that foster the development of the Latin American

4. Avalanches e redes complexas no modelo Kinouchi-Copelli / Avalanches and complex networks in Kinouchi-Copelli model
The capacity of a sensory system in efficiently detecting stimuli is usually given by the dynamic range, a simple measure of the range of stimulus intensity over which the network is sensible enough. Many times biological systems exhibit large dynamic ranges, covering many orders of magnitude. There is no easy explanation for that, since individual neurons p

5. Emprego de redes complexas no estudo das relações entre morfologia individual, topologia global e aspectos dinâmicos em neurociência / Employment of complex network theory on the study of the relations between individual morphology, global topology and dynamical aspects in Neuroscience
A teoria de redes complexas se consolidou nos últimos anos, graças ao seu potencial como ferramenta versátil no estudo de diversos sistemas discretos. É possível enumerar aplicações em áreas tão distintas como engenharia, sociologia, computação, linguística e biologia. Tem merecido atenção, por exemplo, o estudo da organização estrutural do c

6. Proposta e avaliação de um modelo computacional de gerador central de padrões / Proposal and evaluation of a computational model of Central Pattern Generator
The concept of Central Pattern Generator-CPG can be described as neural network capable of producing coordinated rhythmic locomotor activity apart from any external rhythm or sensorial stimuli. As this group of neurons are autonomic and are located in the spinal medulla, is experimentally observed that brainless animal‟s exhibit robotized locomotor act

8. Tratamento com taurina e interferon beta influencia a expressão do complexo de histocompatibilidade principal de classe I (MHC I) e a formação de sinapses em células PC12 / Interferon beta and taurine treatment induce major histocompatibility complex class I (MHC I) upregulation and synapse plasticity in PC12 cells
It has been demonstrated that MHC I up regulation by exogenous treatment with interferon beta (IFN beta) influences the glial reaction and the synaptic elimination process. Also, the amino acid taurine has been shown to positively influence neuronal survival and plasticity. Nevertheless, the establishment of an in vitro model for studying the synaptic format

9. Caracterização citoarquitetônica, neuroquímica e de aferência óptica do complexo parabraquial do sagui (Callithrix jacchus)
The parabrachial complex (PB) is an area of the brainstem responsible for the processing and transmission of essential physiologic information for the survival of the organisms. This region is subdivided in approximately nine subregions, considering morphology, cytoarchitectural and functional characteristic. Its neurons have an extensive network of connecti

10. Regeneração de atrofia de substância branca após a cirurgia de epilesia: evidências estruturais através da morfometria baseada em voxel
OBJECTIVES: To study pre and postoperative WMA in MTLE patients. METHODS: We performed Voxel-Based Morphometry (VBM) with volume of interest (VOI) in 69 controls (mean age, 34.3±11.1 years) and 67 operated patients (mean age, 34.1±10.4 years) with unilateral MTLE. 34 became seizure-free (SzFree-Group), 23 improved (Engel IB-IIA [Partial recovery-group]) an

11. Crises paroxísticas recorrentes em ratos por inibição do transporte de glutamato durante o desenvolvimento / Genesis of recurrent epileptic paroxysmal burst in newborn rats after inhibition of glutamate transporters
It has been previously shown that cell-surface glutamate transporters efficiently control network activity in the maturing rodent brain, preventing the generation of seizures. In particular, inhibition of glutamate transporters by DL-TBOA leads to a pathological EEG pattern in freely moving rat pups. This is composed of partial seizures and recurrent short p

12. Avalanches neuronais durante o ciclo sono-vigÃlia de ratos
Neuronal avalanches are spatiotemporal patterns of neuronal activity that occur spontaneously in supercial layers of the mammalian cortex under various experimental conditions. Previous studies in brain slices and cultured cells have shown that the distribution of sizes P(s) of neuronal avalanches obeys a power law relationship: P(s) Â sÂa , with exponent
