Abstract
Oligodendrocytes are fundamental for the functioning of the nervous system; they participate in several cellular processes, including axonal myelination and metabolic maintenance for astrocytes and neurons. In the mammalian nervous system, they are produced through waves of proliferation and differentiation, which occur during embryogenesis. However, oligodendrocytes and their precursors continue to be generated during adulthood from specific niches of stem cells that were not recruited during development. Deficiencies in the formation and maturation of these cells can generate pathologies mainly related to myelination. Understanding the mechanisms involved in oligodendrocyte development, from the precursor to mature cell level, will allow inferring therapies and treatments for associated pathologies and disorders. Such mechanisms include cell signalling pathways that involve many growth factors, small metabolic molecules, non-coding RNAs, and transcription factors, as well as specific elements of the extracellular matrix, which act in a coordinated temporal and spatial manner according to a given stimulus. Deciphering those aspects will allow researchers to replicate them in vitro in a controlled environment and thus mimic oligodendrocyte maturation to understand the role of oligodendrocytes in myelination in pathologies and normal conditions. In this study, we review these aspects, based on the most recent in vivo and in vitro data on oligodendrocyte generation and differentiation.

Abstract
AIM OF THE STUDY Palicourea coriacea (Cham.) K Schum, is an endemic plant used in the Midwestern Region of Brazil, popularly known as "douradinha do campo" and "congonha do campo". This plant has been used in traditional medicine for several ailments, especially to treat kidney diseases. Since no formal studies on the biological activities and medicinal properties of the ethanolic extract of Palicourea coriacea (PCEE) have been carried out previously, the present study represents the first research into the efficacy of this plant as a diuretic agent employing laboratory rats as test animals. MATERIALS AND METHODS For diuretic activity evaluation we assayed three doses of PCEE (20, 40 and 80mg/kg) and measurement of the urinary volume and electrolytes (Na(+), K(+)) concentration were taken. The acute oral toxicity of PCEE was investigated according to OECD Guideline 423. RESULTS The oral administration of a single dose of PCEE significantly increased the urinary volume in 24h. Additionally, the treatment with PCEE increased, in a dose-dependent manner, the excretion of both, Na(+) and K(+). No sign of toxicity was observed in the animals. CONCLUSIONS The present study confirmed the ethnopharmacological use of Palicourea coriacea as a diuretic agent in the experimental condition tested here. Additionally, this work supports the importance of the preservation of local knowledge as well as the conservation of Brazilian biodiversity.

Abstract
The authors analyzed a family in which three descendants presented with adenocarcinoma of the colon. In two of them the presence of colonic adenomatosis was observed. Another family member, a 13-year-old girl, presented with Turcot syndrome, that is, brain tumor associated with colonic adenomatosis. The nature of the hereditary transmission of Turcot syndrome is hence analyzed, discussing whether it happens through an autosomal recessive or a dominant gene. Undoubtedly the family has colonic adenomatosis, a disease considered of autosomal dominant transmission. Based on the clinical observation, the authors suggest that Turcot syndrome may be determined by an autosomal gene with a pleiotropic effect and variable expressivity.
