1. Bioética, saúde e realidade brasileira
Resumo Este artigo propõe abordagem social, crítica, ativa, humanista, justa e eficaz no combate às desigualdades do sistema de saúde. Busca-se discutir formas de sanar os problemas da assistência no país a partir de análise sociológica que considera questões de classe. A saúde é aqui discutida como direito inalienável de todo cidadão, com base

2. Deglutition pattern in Angle’s Class II malocclusion
ABSTRACT Purpose: to analyze the electromyographic activity of the suprahyoid muscles during deglutition in participants with Angle´s Class II malocclusion. Methods: electromyographic data recordings were performed in the supra-hyoid muscles during swallowing and at rest, in 30 volunteers, 15 Angle´s Class I participants and 15 Angle´s Class II malocclu

3. Diversity among populations goats based on morphometric markers / Diversidade genética entre populações caprinas com base em marcadores morfométricos
The goats were introduced in Brazil by the Portuguese colonizers. Today it is difficult to accurately identify the origin of the Brazilian domestic animals and it is unknown the entire extent of its diversity. The conservation and breeding of domestic animals depend on diversity in the species concerned. Theobjectives of this study were 1. compare different

4. The enviromental dimension of education: the environmental contents of the publicâs schools in the poor communities / A dimensÃo ambiental da educaÃÃo : os conteÃdos ambientais em escolas pÃblicas das comunidades carentes
This dissert is linked to the Programa de Mestrado of the Faculdade de EducaÃÃo da Universidade Federal de UberlÃndia â MG (FACED/UFU)âs research line â Knowing and Educative Practices. Its central question is to verify how the docents practices act with the environmental contents of the public schools in the cityâs poor periphery. To realize this ana

5. "New approaches in machine learning for rule generation, class imbalance and rankings" / "Novas abordagens em aprendizado de máquina para a geração de regras, classes desbalanceadas e ordenação de casos"
Algoritmos de aprendizado de máquina são frequentemente os mais indicados em uma grande variedade de aplicações de mineração dados. Entretanto, a maioria das pesquisas em aprendizado de máquina refere-se ao problema bem definido de encontrar um modelo (geralmente de classificação) de um conjunto de dados pequeno, relativamente bem preparado para o a

6. Plasmodium falciparum malaria: evidence for an isotype imbalance which may be responsible for delayed acquisition of protective immunity.
In view of the recent demonstration that antibodies that are protective against Plasmodium falciparum malaria may act in collaboration with blood monocytes, we investigated the isotype content of sera from individuals with defined clinical states of resistance or susceptibility to malaria. Profound differences in the distribution of each immunoglobulin subcl

7. Trading force for speed: Why superfast crossbridge kinetics leads to superlow forces
Superfast muscles power high-frequency motions such as sound production and visual tracking. As a class, these muscles also generate low forces. Using the toadfish swimbladder muscle, the fastest known vertebrate muscle, we examined the crossbridge kinetic rates responsible for high contraction rates and how these might affect force generation. Swimbladder f

8. Cot deaths in Edinburgh: infant feeding and socioeconomic factors.
One hundred and twenty-six consecutive cases of sudden infant death syndrome (SIDS) in the Edinburgh area have been studied with particular reference to the interrelationship of feeding, associated biochemical changes, and social status. There was an excess of cases born to parents in Social Classes IV and V: the effect was maximal in children who dies beyon

9. Causes of Sex Ratio Bias May Account for Unisexual Sterility in Hybrids: A New Explanation of Haldane's Rule and Related Phenomena
Unisexual hybrid disruption can be accounted for by interactions between sex ratio distorters which have diverged in the species of the hybrid cross. One class of unisexual hybrid disruption is described by Haldane's rule, namely that the sex which is absent, inviable or sterile is the heterogametic sex. This effect is mainly due to incompatibility between X

10. Autosomal-dominant hemochrom-atosis is associated with a mutation in the ferroportin (SLC11A3) gene
Hemochromatosis is a progressive iron overload disorder that is prevalent among individuals of European descent. It is usually inherited in an autosomal-recessive pattern and associated with missense mutations in HFE, an atypical major histocompatibility class I gene. Recently, we described a large family with autosomal-dominant hemochromatosis not linked to

11. Regulation of immunoglobulin (Ig)E synthesis in the hyper-IgE syndrome.
The hyper-IgE (HIE) syndrome is characterized by high IgE serum levels, chronic dermatitis, and recurrent infections. The mechanisms responsible for hyperproduction of IgE in HIE patients are presently unknown. We investigated whether spontaneous in vitro IgE synthesis by PBMC from seven HIE patients was sensitive to signals (cell adhesion, T/B cell cognate

12. Reduction of renal mass is lethal in mice lacking vimentin. Role of endothelin-nitric oxide imbalance.
Modulation of vascular tone by chemical and mechanical stimuli is a crucial adaptive phenomenon which involves cytoskeleton elements. Disruption, by homologous recombination, of the gene encoding vimentin, a class III intermediate filament protein mainly expressed in vascular cells, was reported to result in apparently normal phenotype under physiological co
