1. Dinâmicas motivacionais em aulas de inglês em uma escola pública brasileira
RESUMO Este artigo pretende discutir a inter-relação entre a motivação de uma professora de inglês de uma escola pública federal de nível médio do Brasil e a de seus estudantes sob a perspectiva dos sistemas dinâmicos complexos. Com base em três narrativas orais e 14 entradas de diário, a prática pedagógica da professora foi descrita e seus come

2. Assembly and evaluation of a cooling tower for use in teaching undergraduate activities / Montagem e avaliação de uma torre de resfriamento para uso em atividades de ensino de graduação
This work describes proposal for complementing Process Systems Engineering (PSE) undergraduate learning. Traditional teaching of PSE is normally restricted to modeling and computer simulations, with very little contact with actual processes. We felt that applying theoretical concepts to practical problems would be very welcome by the students and improve the

3. Species assembly rules and the biodiversity-ecosystem functioning relationship / Regras entre assemblÃias de espÃcies: relaÃÃo entre biodiversidade e funcionamento do ecossistema
The biological diversity of ecosystems has important implications for their functioning. However, in order for reliable predictions to be made on the effects of species extinctions and/or additions on particular ecosystem functions, accurate knowledge is required on the ways in which species interact. These interactions in turn are important drivers of commu

4. Near-infrared-emissive polymersomes: Self-assembled soft matter for in vivo optical imaging
We demonstrate that synthetic soft materials can extend the utility of natural vesicles, from predominantly hydrophilic reservoirs to functional colloidal carriers that facilitate the biomedical application of large aqueous-insoluble compounds. Near-infrared (NIR)-emissive polymersomes (50-nm- to 50-μm-diameter polymer vesicles) were generated through coope

5. Alignment enhances the cell-to-cell transfer of pilus phenotype
Social gliding motility of Myxococcus xanthus requires polar type IV pili. Tgl mutants lack pili and lack social motility. However, both defects can be rescued phenotypically, but not genotypically, when tgl+ donor and tgl− recipient cells make physical contact with each other. What is the cellular and molecular basis of this transfer of phenotype, which i

6. The murine SNF5/INI1 chromatin remodeling factor is essential for embryonic development and tumor suppression
The assembly of eukaryotic DNA into nucleosomes and derived higher order structures constitutes a barrier for transcription, replication and repair. A number of chromatin remodeling complexes, as well as histone acetylation, were shown to facilitate gene activation. To investigate the function of two closely related mammalian SWI/SNF complexes in vivo, we in

7. Early Experience with Biodegradable Implants in Pediatric Patients
We retrospectively studied nine children and adolescents with congenital malformations, large reconstruction after tumor excision, fractures and osteotomies of the upper extremity, and hand trauma with bone and soft tissue defects treated by internal synthesis using a biocopolymer of L- and DL-stereoisomers of lactic acid polymers and trimethylenecarbonate.

8. De novo decorin gene expression suppresses the malignant phenotype in human colon cancer cells.
The rapid progress in the cloning of proteoglycan genes has enabled investigators to examine in depth the functional roles these polyhedric molecules play in the control of cell proliferation. Decorin, a leucine-rich proteoglycan expressed by most connective tissues, is a prototype molecule that regulates cellular growth via two mechanisms: modulation of gro

9. Trans receptor inhibition of human glioblastoma cells by erbB family ectodomains
Our aim has been to understand the features of erbB receptor homo- and heterodimer assembly to develop approaches to disrupt receptor activation. We have developed a general approach to cause erbB receptor-specific trans inhibition of human neoplasia. The clonal progression of human astrocytomas to a more malignant phenotype often involves the amplification

10. Structural basis for the enhancement of eIF4A helicase activity by eIF4G
The eukaryotic translation initiation factors 4A (eIF4A) and 4G (eIF4G) are crucial for the assembly of the translationally active ribosome. Together with eIF4E, they form the eIF4F complex, which recruits the 40S subunit to the 5′ cap of mRNA. The two-domain RNA helicase eIF4A is a very weak helicase by itself, but the activity is enhanced upon interactio

11. Genetic analysis of sequences in maltoporin that contribute to binding domains and pore structure.
Maltoporin (LamB protein) is a maltodextrin transport protein in the outer membrane of Escherichia coli with binding sites for bacteriophage lambda and maltosaccharides. Binding of starch by bacteria was found to inhibit swarming of Escherichia coli in soft agar plates; the inhibition was dependent on the maltodextrin affinity of maltoporin. On the basis of
