A case of ganglioglioma or neuroastrocytoma of the spinal cord in a 78-year-old man is reported. Diagnosis was based on the histological identification of the neoplastic cells and on the study of the ...architecture of the tumour. The presence of cellular anaplasia, sometimes of marked degree, and of small nests of infiltration suggested an initial malignant behaviour regarding both cellular types. A survey of the five reported cases of spinal ganglioglioma is presented.
We evaluated the changes in biochemical and nutritional profiles of Japanese-Brazilians with and without metabolic syndrome after two years of participation in the intervention program.
It was a ...non-controlled experimental study. The biochemical and clinical assessments were conducted at baseline (2005), after a year (2006) and after two years (2007) of intervention. On the present study, data of 360 individuals, who participated on the three assessments were considered.
Both groups presented improvements on the anthropometric and metabolic profile, after two years of intervention. It was observed reduction in the intake of total fat, saturated fat, and dietary cholesterol, and increased intake of fiber among men without metabolic syndrome. It was observed reduction in the intake of total fat (p = 0,003) and monounsaturated fatty acid (p = 0,002).
The results showed a positive impact of the lifestyle intervention program in metabolic and nutritional profile of Japanese-Brazilians with and without metabolic syndrome.
OBJETIVO: Avaliar as mudanças nos perfis metabólico e nutricional de nipo-brasileiros com e sem síndrome metabólica, após dois anos de participação em programa de intervenção. MATERIAIS E MÉTODOS: ...Trata-se de estudo experimental não controlado. A pesquisa incluiu três momentos de avaliação clínico-laboratorial: basal (2005), após o primeiro ano de intervenção (2006) e ao final do segundo ano (2007). Na presente análise, utilizaram-se informações de 360 indivíduos examinados nos três momentos. RESULTADOS: Ambos os grupos apresentaram melhora no perfil metabólico e antropométrico, após o segundo ano de intervenção. Observaram-se diminuição na ingestão de gorduras totais, ácidos graxos saturados, colesterol e aumento de fibras totais nos homens sem síndrome metabólica. No sexo feminino sem síndrome metabólica, observou-se redução de gordura total (p = 0,003) e ácido graxo monoinsaturado (p = 0,002). CONCLUSÃO: Os resultados encontrados mostraram impacto positivo do programa de intervenção nos perfis metabólico e nutricional dos nipo-brasileiros com e sem síndrome metabólica.

The decrease in c-myc mRNA expression occurring in leukemia cell lines induced to differentiate is supposed to be an early event of the commitment to the differentiation program. Alternatively, the ...decrease in c-myc mRNA expression could be simply a consequence of loss of the self-renewal capability characteristic of the terminal differentiated phenotypes. In an attempt to clarify these hypotheses, we analysed comparatively the kinetics of variations in c-myc mRNA expression, hemoglobin synthesis, DNA and RNA syntheses, cell cycle kinetics and self-renewal capability in normal and hemin-treated K562 leukemia cells exposed for different periods of time to the antitumoral antibiotic doxorubicin. Times of exposure to doxorubicin were either 2 h, which resulted in reversible induction of hemoglobin synthesis without significant cytostatic effects, or continuously for more than 5 days, which resulted in an irreversible induction of hemoglobin synthesis and in the complete and irreversible loss of self-renewal activity. Comparative analysis of the experimental data indicated that the decrease in c-myc mRNA expression correlated with the loss of replicative activity, possibly due to an irreversible cytostatic effect of the long exposure to doxorubicin, but not with the commitment to the differentiation programs.
