13. TRÊS ENSAIOS SOBRE A METODOLOGIA DE APREÇAMENTO DE ATIVOS UTILIZANDO OPÇÕES REAIS / THREE ESSAYS ON ASSET PRICING APPLYING REAL OPTIONS METHODOLOGY
The dissertation presents three economic essays examining situations where the real options approach can be useful in the definition of regulatory policies, investment strategies and pricing of sovereign risk. The first essay considers the new regulation oriented to interconnection costs of telecommunications networks and proposes adjustments in calculating

14. AnÃlise da regulaÃÃo transcricional de genes de Yersinia em Escherichia coli
Yersiniae possess a type III secretion system, responsible for the translocation of proteins known as Yops, to the interior of the eukaryotic cells of the host. The YopH protein is a tyrosine phosphatase that desphosphorylates signalling molecules and impairs phagocytosis in macrophages. For its efficient secretion it needs the presence of the chaperone SycH

15. ESSAYS ON LIBERALIZATION, REGULATION AND INVESTMENT IN HYDROTHERMAL SYSTEMS / ENSAIOS SOBRE LIBERALIZAÇÃO, REGULAÇÃO E INVESTIMENTO EM SISTEMAS HIDROTÉRMICOS
This dissertation is structured into 3 essays in which I analyze the economic effects of regulation and liberalization of hydrothermal systems. So far empirical and theoretical studies about power markets have been done mainly for thermal systems, in which equilibrium conditions reflect the fact that current production decisions can be analyzed separately fr

17. Regulation of Thymidine Metabolism in Escherichia coli K-12: Optimal Conditions for the Assay of 1,5-Phosphodeoxyribomutase in Ultrasonic Extracts
Assay conditions have been established which allow maximum expression of phosphodeoxyribomutase activity in ultrasonic extracts of Escherichia coli K-12. The enzyme requires 2-mercaptoethanol, manganous ions, and glucose 1,6-diphosphate for optimal activity. When cells are grown in minimal medium with glycerol as the carbon source and supplemented with 10−

18. Estrogen receptor transcription and transactivation: Estrogen receptor alpha and estrogen receptor beta - regulation by selective estrogen receptor modulators and importance in breast cancer
Estrogens display intriguing tissue-selective action that is of great biomedical importance in the development of optimal therapeutics for the prevention and treatment of breast cancer, for menopausal hormone replacement, and for fertility regulation. Certain compounds that act through the estrogen receptor (ER), now referred to as selective estrogen recepto

19. Regulation of melanoma by the embryonic skin.
This report focuses on the regulation of murine melanoma by the embryonic skin. A surgical technique was developed to allow injection of B16 melanoma cells into the embryo in utero. A significant decrease in incidence of tumors was noted, which correlated with the time of arrival of normally migrating premelanocytes into the skin. Media were conditioned from

20. Transcriptional regulation of SSA3, an HSP70 gene from Saccharomyces cerevisiae.
The SSA3 gene of Saccharomyces cerevisiae, a member of the HSP70 multigene family, is expressed at low levels under optimal growth conditions and is dramatically induced in response to heat shock. Sequences coinciding with two overlapping heat shock elements, located 156 base pairs upstream of the transcribed region, were necessary and sufficient for regulat

21. In Vitro Activation of a Galactosyl Transferase Involved in the Osmotic Regulation of Ochromonas1
Osmotic regulation in the flagellate Ochromonas malhamensis Pringsheim is mainly mediated by fluctuations in the pool size of α-galactosyl-(1→1)-glycerol (isofloridoside). A regulated key enzyme of isofloridoside metabolism is the galactosyl transferase producing isofloridoside phosphate. The activity of this enzyme in crude extracts can be increased 5- t

22. The DNA-binding specificity of SOX9 and other SOX proteins.
SOX (SRY-related HMG box) proteins are transcription factors that have critical roles in the regulation of numerous developmental processes. They share at least 50% homology in their HMG domains, which bind the DNA element AACAAT. How different SOX proteins achieve specific regulation of target genes is not known. We determined the DNA-binding specificity of

23. The BpsIR Quorum-Sensing System of Burkholderia pseudomallei
BpsIR, a LuxIR quorum-sensing homolog, is required for optimal expression of virulence and secretion of exoproducts in Burkholderia pseudomallei. Cell density-dependent expression of bpsI and bpsR, the positive regulation of bpsIR expression by BpsR, and the synthesis of N-octanoyl-homoserine lactone (C8HSL) by BpsI are described in this report.

24. Tyrosine kinase signalling in breast cancer: ErbB family receptor tyrosine kinases
ERBB family receptor tyrosine kinases are overexpressed in a significant subset of breast cancers. One of these receptors, HER2/neu, or ErbB-2, is the target for a new rational therapeutic antibody, Herceptin. Other inhibitors that target this receptor, and another family member, the epidermal growth factor (EGF) receptor, are moving into clinical trials. Bo
