1. Reflection of cardinal functions / Reflexão de funções cardinais
This work investigates problems about reflection of cardinal functions, using techniques such as elementary submodels and PCF Theory. We show that the Lindelöf degree reflects all the strongly inaccessible cardinals and that a example of a space in which the same cardinal function does not reflect a weakly inaccessible cardinal requires \"0# exists\".

2. Reflection of cardinal functions and of metrizability / Reflexão de funções cardinais e da metrizabilidade
O conceito de reflexão em topologia expressa o fato de que um espaço satisfaz uma dada propriedade sempre que esta é satisfeita por seus subespaços "menores". Neste trabalho, estuda-se a reflexão de propriedades envolvendo a maioria das principais funções cardinais e metrizabilidade, bem como outras propriedades relacionadas. São discutidos problemas

3. MODELING DEVELOPMENT AND SOIL WATER BALANCE IN WHEAT / MODELAGEM DO DESENVOLVIMENTO E DO BALANÇO DE ÁGUA NO SOLO EM TRIGO
Wheat is the main winter crop in Rio Grande do Sul State. Temperature and photoperiod are the major environmental factors that control development in wheat. Wheat plants exposed to cold, non freezing temperatures induce them to enter the reproductive phase. Temperature and photoperiod response functions are used to simulate the wheat development. Development

4. β3-integrin–deficient mice are a model for Glanzmann thrombasthenia showing placental defects and reduced survival
β3 integrins have been implicated in a wide variety of functions, including platelet aggregation and thrombosis (αIIbβ3) and implantation, placentation, angiogenesis, bone remodeling, and tumor progression (αvβ3). The human bleeding disorder Glanzmann thrombasthenia (GT) can result from defects in the genes for either the αIIb or the β3 subunit. In or

5. Disparate Roles for the Regulatory A Subunit Isoforms in Arabidopsis Protein Phosphatase 2A
The heterotrimeric protein phosphatase 2A (PP2A) complex comprises a catalytic subunit and regulatory A and B subunits that modulate enzyme activity and mediate interactions with other proteins. We report here the results of a systematic analysis of the Arabidopsis (Arabidopsis thaliana) regulatory A subunit gene family, which includes the ROOTS CURL IN NAPH

6. Rabies Virus Stimulates Nitric Oxide Production and CXC Chemokine Ligand 10 Expression in Macrophages through Activation of Extracellular Signal-Regulated Kinases 1 and 2
Macrophages represent an essential part of innate immunity, and the viral infection of macrophages results in the release of multiple proinflammatory mediators, such as nitric oxide (NO), cytokines, and chemokines. This study was undertaken to define the molecular mechanism of macrophage activation in response to rabies virus (RV) infection. In RAW264 murine

7. Prions in Saccharomyces and Podospora spp.: Protein-Based Inheritance
Genetic evidence showed two non-Mendelian genetic elements of Saccharomyces cerevisiae, called [URE3] and [PSI], to be prions of Ure2p and Sup35p, respectively. [URE3] makes cells derepressed for nitrogen catabolism, while [PSI] elevates the efficiency of weak suppressor tRNAs. The same approach led to identification of the non-Mendelian element [Het-s] of t
