1. O transtorno depressivo pode ser geneticamente herdado?
Sobre os fatores genéticos da depressão, a herdabilidade da depressão ainda não é consenso na literatura cientifica. No entanto, segundo alguns estudos estima-se que 37% dos casos possam ter uma relação genética, mesmo que essas relações sejam posteriormente moduladas pelo ambiente – ou seja, embora os genes possam ser relevantes para o surgim

2. Does Decreased SNX10 Serve as a Novel Risk Factor in Atrial Fibrillation of the Valvular Heart Disease? - A Case-Control Study
Abstract Introduction: Atrial fibrillation (AF) is the most common sustained arrhythmia. Sorting nexin 10 (SNX10) has been reported to be an important regulator in embryonic development and human diseases, however, little is known about its role in cardiac disease. The aim of this study was to investigate the clinical significance of SNX10 expression in AF.

3. Preventive Effects of Ellagic Acid on Nucleus Tractus Solitarius Electrical Activity and Oxidative Stress Altered by Cerebral Global Ischemia/Reperfusion in Rat
ABSTRACT Cerebral ischemia commonly occurs when the blood flow to the entire brain or some part of the brain is disrupted. Global cerebral ischemia attenuates the nucleus tractus solitaries (NTS) EEG rhythm, increases the free radicals production and brain inflammation. Ellagic acid (EA) has antioxidative and anti-inflammatory effects against neural damages.

4. Relationship between Brain Natriuretic Peptide and Recurrence of Atrial Fibrillation after Successful Electrical Cardioversion: an Updated Meta-Analysis
Abstract Objective: To investigate the relationship between brain natriuretic peptide and recurrence of atrial fibrillation after successful electrical cardioversion. Methods: Medline and Embase databases were used to identify publications evaluating BNP/N-Terminal (NT)-proBNP levels in association with atrial fibrillation recurrence after successful elect

5. Dinâmica do sistema córtico-hipocampal durante o condicionamento contextual de medo / Cortico-hippocampal system dynamics during contextual fear conditioning
O estabelecimento das memórias de longo prazo requer uma efetiva comunicação do hipocampo com o neocortex. Um mecanismo plausível envolvido na comunicação neuronal e na plasticidade sináptica é a sincronização da atividade elétrica cerebral na frequência teta. Estudos recentes mostraram que a sincronização entre os ritmos teta do hipocampo e do

6. Morning and nocturnal serum melatonin rhythm levels in patients with major depressive disorder: an analytical cross-sectional study
CONTEXT AND OBJECTIVE: The pineal gland is an adaptive organ that precisely regulates the biological rhythms of melatonin brain hemostasis. Variation in the regulation of melatonin rhythms is a likely cause of depressive disorder. The purpose of this study was to measure serum melatonin levels in patients with major depressive disorder (MDD) and normal contr

7. Em busca da região epileptiforme em pacientes com epilepsia do lobo temporal: métodos alternativos baseados em fMRI e EEG-fMRI / Searching for epileptiform region in patients with temporal lobe epilepsy: alternative methods based on fMRI and EEG-fMRI
Temporal lobe epilepsy (TLE) is the most common and resistant form of epilepsy to anti-epileptic drug. There are several types of anti-epileptic drugs used in seizure control. However, in some cases drug treatment is not effective and surgery to remove the epileptogenic zone (EZ) is a recommended alternative. EZ is a theoretical concept and there are many te

8. 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

10. Para um estudo da estruturação ritmica na fala disartrica / Towards a study of the rhythmic structural in dysarthric speech
Dysarthria is a speech disorder caused by neuromotors problems. These neuromotors problems may cause breath, phonation, resonance and speech articulation disturbance. The cause of these neuromotors problems can be the traumatic brain injury (TBI). TBI is a lesion that result of cerebral aggression, a collision in the head/or a fall happening cranial breaking

Biological clocks are endogenous timekeepers that are present both in eukaryotic as in prokaryotic organisms. Different clocks have different periods, and those that have about 24h of oscillation are called circadian clocks. In mammals, the first identified circadian clock is located in the suprachiasmatic nucleus, in the hipothalamus. It is now well known t

12. Para um estudo da estruturação ritmica na fala disartrica / Towards a study of the rhythmic structural in dysarthric speech
A disartria é uma desordem da fala decorrente de comprometimentos neuromusculares. Tais comprometimentos podem causar alterações na respiração, na fonação, na ressonância e na articulação da fala. Estes comprometimentos podem ser decorrentes de traumatismo craniano (TC). O TC é uma agressão cerebral resultante de uma pancada na cabeça e/ou uma q
