1. Its not fiction, it is fac: tensions between instrument and object: a study about the use of cinema in education. / Não é fita, é fato: tensões entre instrumento e objeto: um estudo sobre a utilização do cinema na educação.
This dissertation aims at discussing the relationship between the school and the use of audiovisuals, mainly, cinema. Our starting point is that even though schools are more equipped than ever, the insertion of the cinema in schools is not effective. The educational importance of the cinema since the beginning of the 20th Century has been recognized and in t

2. Úlcera de perna: caracterização clínica e perfil imunohistopatológico da cicatrização na presença da biomembrana de látex natural da seringueira Hevea brasiliensis / Leg ulcer: clinical caracterization and immunohistopathologic profile on wound healing in the presence of natural latex biomembrane of rubber tree Hevea brasiliensis.
Úlcera de perna é uma doença muito freqüente na população idosa. Inúmeros são os tipos de curativos atualmente usados para tratamento das úlceras de perna, com diferentes indicações, vantagens e desvantagens, cuja eficácia não está bem esclarecida devido à descontinuidade dos tratamentos e os custos envolvidos em algumas situações. Para aval

3. Isolation and analysis of the acetate regulatory gene, facB, from Aspergillus nidulans.
The facB gene of Aspergillus nidulans is thought to be involved in acetate induction of enzymes required for acetate utilization and of the acetamidase encoded by the multiply regulated amdS gene. In addition, some evidence suggests that the facB gene has a structural as well as a regulatory role in acetate metabolism. The facB gene was cloned from a cosmid

4. Induction of the acetamidase of Aspergillus nidulans by acetate metabolism.
Growth tests and enzyme determinations strongly suggest that the acetamidase of Aspergillus nidulans is induced by a product of acetate metabolism rather than the substrate, acetamide. The cis-dominant mutation, amdI9, which is closely linked to amdS, the structural gene for the acetamidase, results in greatly increased sensitivity to induction by acetate me

5. Convergence of integrin and growth factor receptor signaling pathways within the focal adhesion complex.
Extracellular matrix controls capillary endothelial cell sensitivity to soluble mitogens by binding integrin receptors and thereby activating a chemical signaling response that rapidly integrates with growth factor-induced signaling mechanisms. Here we report that in addition to integrins, growth factor receptors and multiple molecules that transduce signals

6. The Fanconi Anemia Protein FANCC Binds to and Facilitates the Activation of STAT1 by Gamma Interferon and Hematopoietic Growth Factors
Hematopoietic progenitor cells from Fanconi anemia (FA) group C (FA-C) patients display hypersensitivity to the apoptotic effects of gamma interferon (IFN-γ) and constitutively express a variety of IFN-dependent genes. Paradoxically, however, STAT1 activation is suppressed in IFN-stimulated FA cells, an abnormality corrected by transduction of normal FANCC

7. Identification of the sites of action for regulatory genes controlling the amdS gene of Aspergillus nidulans.
The amdS gene of Aspergillus nidulans, which encodes an acetamidase enzyme, is positively regulated by the trans-acting genes amdR, facB, amdA, and areA. Sequence changes in several cis-acting mutations in the 5' region of the gene which specifically affect amdS regulation were determined. The amdI9 mutation, which results in increased facB-dependent acetate

8. Regulation of the acuF Gene, Encoding Phosphoenolpyruvate Carboxykinase in the Filamentous Fungus Aspergillus nidulans
Phosphoenolpyruvate carboxykinase (PEPCK) is a key enzyme required for gluconeogenesis when microorganisms grow on carbon sources metabolized via the tricarboxylic acid (TCA) cycle. Aspergillus nidulans acuF mutants isolated by their inability to use acetate as a carbon source specifically lack PEPCK. The acuF gene has been cloned and shown to encode a prote

9. Phenotypic correction of Fanconi anemia in human hematopoietic cells with a recombinant adeno-associated virus vector.
Fanconi anemia (FA) is a recessive inherited disease characterized by defective DNA repair. FA cells are hypersensitive to DNA cross-linking agents that cause chromosomal instability and cell death. FA is manifested clinically by progressive pancytopenia, variable physical anomalies, and predisposition to malignancy. Four complementation groups have been ide
