1. Controle hormonal da próstata feminina do gerbilo sob influência de múltiplas prenhezes e reposição hormonal / Hormonal control of the gerbil s female prostate : influence of multiple pregnancies and hormone replacement
The gerbil female prostate is located paraurethrally and has all the main histological components of the male prostate, like secretor epithelium and fibromuscular stroma. This gland, like the prostate in males, is targeted by testosterone action, which promotes morphofunctional development. Furthermore, estrogens are required to maintain the male and female

2. CARBAMAZEPINA NO ESTADO SÓLIDO E SUA SUSCEPTIBILIDADE POLIMÓRFICA
Many pharmaceutical products are in solid state for reasons of stability or ease of handling during the stages of drug development. The polymorphism is the crystallization of the same substance in different crystalline architectures. This phenomenon is very common in pharmaceuticals and is associated with differences in packing arrangements of crystalline. T

3. Pesquisadores, populações locais e áreas protegidas: entre a instabilidade dos lados e a multiplicidade estrutural das posições / Distinctions and similarities among researchers working on protected areas and local populations: multiplicity of "sides" and structural instability of "stands".
A relação entre populações locais e áreas protegidas é tema hoje extremamente controvertido no âmbito científico, mobilizando a atenção de cientistas interessados tanto em pesquisar questões específicas como em interferir em políticas públicas a ele direcionadas. Se há um consenso entre especialistas, é que estamos diante de um contexto discu

4. Cenografia e ethos: os discursos de uma instituicção de ensino superior privada
The crisis of taylorism and fordism, in the beginning of 1970s, made capitalism began to present clear signs of a structural crisis that affected the work world and demanded an immediate answer. This one came as a form of accumulation different from the previous one, "flexible" capitalism, translated in a process of capital reorganization named neoliberalism

5. HYDROELETRIC GENERATION ASSET VALUATION BY REAL OPTIONS IN DICRETE TIME / AVALIAÇÃO DE ATIVOS DE GERAÇÃO HIDRELÉTRICA ATRAVÉS DA TEORIA DE OPÇÕES REAIS EM TEMPO DISCRETO
The Brazilian electric sector comes suffering strong structural changes, whose main objective is to create a competitive to allow the sector to grow not more for state investments, but for the private capital. The Agência Nacional de Energia Elétrica (ANEEL) starts to offer a multiplicity of chances of investments, generated mainly for the recent implantat

6. Segmentation and behaviour modelling of brazilian urban transport users. / Segmentação e modelagem comportamental de usuários dos serviços de transporte urbano brasileiros.
Any "business" principle of survival is the understanding of both needs or desires of goods or services consumers. Success of tangible goods depend on the observation of market specifications such as form, function, durability, safety, availability, status and price. For services, on the other hand, consumers satisfaction factors are more obscure and difficu

7. Action of Interferon: Kinetics and Differential Effects on Viral Functions
A highly purified rabbit interferon was tested for its capacity to inhibit various manifestations of infection of primary rabbit kidney (RK) cells with vesicular stomatitis (VS) virus. A kinetic analysis of the actinomycin-sensitive phase of interferon-induced cellular resistance revealed that RK cells could transcribe virtually all of the hypothetical antiv

8. Production of hybridomas secreting monoclonal antibodies to the human leukocyte interferons.
Thirteen monoclonal antibodies to human leukocyte interferon have been obtained. They exhibit different patterns of binding to purified leukocyte interferon species that are consistent with the structural multiplicity of the human leukocyte interferons. These antibodies will be useful as probes into the structure of the human leukocyte interferons, for their

9. Nucleosome-like structural subunits of intranuclear parental adenovirus type 2 DNA.
The intranuclear structure of parental adenovirus 2 DNA was studied using digestion with micrococcal nuclease as a probe. When cultures were infected with 32P-labeled virions, at a multiplicity of 3,000 particles per cell, 14 to 21% of parental DNA penetrated the cell and reached the nucleus. Of this parental DNA, 60% could be solubilized by extensive digest

10. Reovirus: Effect of Noninfective Viral Components on Cellular Deoxyribonucleic Acid Synthesis
We determined the effects of noninfective reovirus components on cellular deoxyribonucleic acid (DNA) synthesis. Reovirus inactivated by ultraviolet light inhibited cellular DNA synthesis, whereas reovirus cores and empty capsids did not. Both cores and empty capsids were adsorbed to cells. Adenine-rich ribonucleic acid (RNA) from reovirus, adsorbed to cells

11. Structural and functional aspects of the multiplicity of Neu differentiation factors.
We used molecular cloning and functional analyses to extend the family of Neu differentiation factors (NDFs) and to explore the biochemical activity of different NDF isoforms. Exhaustive cloning revealed the existence of six distinct fibroblastic pro-NDFs, whose basic transmembrane structure includes an immunoglobulin-like motif and an epidermal growth facto

12. Restriction of porcine parvovirus replication in nonpermissive cells.
Swine testicle (ST) cells and Madin-Darby canine kidney (MDCK) cells differ in their ability to support replication of porcine parvovirus (PPV). Viral replication events in ST cells, a permissive cell type, and MDCK cells, a nonpermissive cell type, were compared in an attempt to elucidate putative mechanisms of restrictive virus replication. Radiolabeled PP
