1. Manual and semi-automatic quantification of in vivo ¹H-MRS data for the classification of human primary brain tumors
In vivo proton magnetic resonance spectroscopy (¹H-MRS) is a technique capable of assessing biochemical content and pathways in normal and pathological tissue. In the brain, ¹H-MRS complements the information given by magnetic resonance images. The main goal of the present study was to assess the accuracy of ¹H-MRS for the classification of brain tumors i

2. Classification of brain tumor extracts by high resolution ¹H MRS using partial least squares discriminant analysis
High resolution proton nuclear magnetic resonance spectroscopy (¹H MRS) can be used to detect biochemical changes in vitro caused by distinct pathologies. It can reveal distinct metabolic profiles of brain tumors although the accurate analysis and classification of different spectra remains a challenge. In this study, the pattern recognition method partial

3. Disseminação peritonial de neurocitoma central: relato de caso
OBJETIVO: Neurocitoma central é tumor de baixo grau, de origem neuroglial e uma entidade neurológica relativamente nova. Poucos casos foram relatados na literatura e seu comportamento biológico é ainda incerto. Alguns casos apresentam comportamento agressivo (recorrência local, diferenciação maligna ou disseminação liquórica) e desafiam a visão in

4. Persistent human immunodeficiency virus type 1 infection in human fetal glial cells reactivated by T-cell factor(s) or by the cytokines tumor necrosis factor alpha and interleukin-1 beta.
Human immunodeficiency virus type 1 (HIV-1) infection of the brain has been associated with a severe dementing illness in children and adults. However, HIV-1 antigens are most frequently found in macrophages and microglial cells. To determine the extent of susceptibility of neuroglial cells to infection, the HIV-1 genome was introduced into cells cultured fr
