1. First report of an outbreak of cerebral coenurosis in Dhofari goats in Oman
Resumo Este estudo documentou o primeiro surto de coenurose cerebral em cabras em Salalah, Oman. A morte de 130 (16,6%) caprinos adultos nativos (n=780) foi relatada de janeiro a junho de 2017. As cabras afetadas mostraram distúrbios neurológicos, que culminaram em óbito. Investigações para deficiência de tiamina, polioencefalomalácia, encefalite por

2. Optimized Exon-Exon Junction Library and its Application on Rodents' Brain Transcriptome Analysis
ABSTRACT Background: Alternative splicing (AS), which plays an important role in gene expression and functional regulation, has been analyzed on genome-scale by various bioinformatic approaches based on RNA-seq data. Compared with the huge number of studies on mouse, the AS researches approaching the rat, whose genome is intermedia between mouse and human,

3. Cortical branches of the middle cerebral artery in silver fox (Vulpes vulpes)
ABSTRACT: The study of the vascularization of the cerebrum in silver fox was performed on 80 cerebral hemispheres. It was found that the middle cerebral artery is the strongest vessel supplying blood to the cerebrum. The artery gets divided into ten permanent branches. Two olfactory arteries supply the region of the cerebrum located on the border between the

4. Avaliação de substância branca através de imagem por tensor de difusão em crianças em risco e portadoras de transtorno bipolar / Evaluation of white matter using diffusion tensor imaging in children at-risk and with bipolar disorder
O Transtorno de Humor Bipolar (THB) acomete até 3% dos adultos e os filhos desses pacientes constituem uma população em risco para o desenvolvimento de transtornos psiquiátricos. No entanto, faltam marcadores que permitam a identificação precoce dos indivíduos que apresentam maior vulnerabilidade para o desenvolvimento de psicopatologia. Estudos preli

5. Bromopyrrole alkaloids from the caribbean sponge Agelas cerebrum
Bioguided fractionation of Agelas cerebrum crude extract resulted in isolation of four bromopyrrole and four bromopyrrole aminoimidazole alkaloids, identified as 5-bromopyrrole-2-carboxylic acid (1), 4-bromopyrrole-2-carboxylic acid (2), 3,4-bromopyrrole-2-carboxylic acid (3), 4,5-bromopyrrole-2-carboxylic acid (4), oroidin (5), bromoageliferin (6), dibromoa

6. Chronic postnatal administration of methylmalonic acid provokes a decrease of myelin content and ganglioside N-acetylneuramic acid concentration in cerebrum of young rats
Levels of methylmalonic acid (MMA) comparable to those of human methylmalonic acidemia were achieved in blood (2-2.5 mmol/l) and brain (1.35 µmol/g) of rats by administering buffered MMA, pH 7.4, subcutaneously twice a day from the 5th to the 28th day of life. MMA doses ranged from 0.76 to 1.67 µmol/g as a function of animal age. Control rats were treated

7. Relação dos pontos-chave cirúrgicos no crânio com áreas eloquëntes detectadas por ressonância magnética funcional / Relation of surgical key-points in skull with eloquent areas detected by functional magnetic resonance
Neuroimaging studies have a pivotal role in pre-surgical assessment of patients with brain lesions. Magnetic Resonance Imaging (MRI) and Computerized Tomography (CT) are established techniques providing anatomic information of the lesion and surrounding areas. Functional MRI (fMRI) is a recent method applied to probe brain function via hemodynamic response o

8. Avaliação da expressão gênica na doença de Alzheimer através da técnica de cDNA microarray em amostras de cérebro postmortem humano / Evaluation of the gene expression in Alzheimer´s disease by cDNA microarray approach from human postmortem brain samples
Alzheimers disease (AD) has received intense study during the past decades. The pathophysiology of AD has been clarified but the diagnosis of AD is still imperfect. On one hand, about 20% of patients diagnosed with probable AD are found, at autopsy, to not meet the pathological definition of the disease. On the other hand, why some subjects have high AD neur

9. AvaliaÃÃo da qualidade de imagem e do Ãndice volumÃtrico de Kerma Ar em tomografia computadorizada (CVOL) em Recife / Image quality and volume computed tomography Air Kerma index (CVOL) evaluation in Recife
The Computed Tomography (CT) is an important diagnostic imaging method, widely used. However, in spite of all the advantages and technologic advances within the CT scanners, the tomographic procedures result in high absorbed doses to patients. The main objective of this work was to perform a dosimetric study of CT scanners located at Recife and to evaluate t

Análise morfométrica voxel-a-voxel de estudos de ressonância magnética do crânio em transtornos psiquiátricos e neurológicos: implementação e otimização de métodos / Voxel-based morphometry analysis of brain magnetic resonance studies in psychiatry and neurologic disorders: implementation and optimization of methods
INTRODUÇÃO: O processamento de imagens de ressonância magnética (RM) estrutural tem sido amplamente utilizado em pesquisas neuro-psiquiátricas. Os métodos mais usados para este fim são a volumetria manual por regiões de interesse (regions of interest - ROIs) e a morfometria baseada no voxel (Voxel-based morphometry - VBM). Nesta tese, foi usado um ba

12. Rapid eye movement sleep deprivation induces an increase in acetylcholinesterase activity in discrete rat brain regions
Some upper brainstem cholinergic neurons (pedunculopontine and laterodorsal tegmental nuclei) are involved in the generation of rapid eye movement (REM) sleep and project rostrally to the thalamus and caudally to the medulla oblongata. A previous report showed that 96 h of REM sleep deprivation in rats induced an increase in the activity of brainstem acetylc
