1. Algoritmos algebricos para enumerar e isolar zeros polinomiais complexos / Algebraic algorithms for enumerate and isolate complex polynomial zeros
O presente trabalho trata do problema de isolar zeros de polinômios complexos. Muitos algoritmos calculam zeros polinomiais, a partir de regiões iniciais disjuntas, cada uma contendo um único zero. Entretanto o problema de obter tais regiões ainda e alvo de estudo, uma vez que as soluções propostas ainda não são satisfatórias. A obtenção de regiõ

2. RNA polymerase I promoter and splice acceptor site recognition affect gene expression in non-pathogenic Leishmania species
Leishmania (Sauroleishmania) tarentolae has biotechnological potential for use as live vaccine against visceral leishmaniasis and as a system for the over expression of eukaryotic proteins that possess accurate post-translational modifications. For both purposes, new systems for protein expression in this non-pathogenic protozoan are necessary. The ribosomal

3. Leishmania tarentolae minicircles of different sequence classes encode single guide RNAs located in the variable region approximately 150 bp from the conserved region.
The complete sequences of three kinetoplast DNA minicircles (B4, D3 and D12) from Leishmania tarentolae are reported. All L. tarentolae minicircles encode single gRNAs localized within the variable region approximately 150 bp from the conserved region. The 5' termini and tentative 3' termini of the new gRNAs were determined and the gene sequences and flankin

4. Molecular Epidemiology of Genital Chlamydia trachomatis Infection in High-Risk Women in Senegal, West Africa
The prevalence and heterogeneity of Chlamydia trachomatis infections in a cohort of female sex workers in Dakar (Senegal) were determined by using endocervical-swab-based PCR DNA amplification assays. The overall prevalence of cervical chlamydial infection was 28.5% (206 of 722), and most of these infections were asymptomatic. An increased number of sexual p

5. Domains determining the functional distinction of the fission yeast cell cycle "start" molecules Res1 and Res2.
In Schizosaccharomyces pombe the "start" of the cell cycle is regulated by two parallel, functionally overlapping complexes composed of Res1-Cdc10 and Res2-Cdc10. Res1 and Res2 are structurally very homologous and are required for the start of the mitotic and meiotic cycle, respectively. We have addressed the question which parts of the proteins are essentia

6. Cloning and characterization of a glutathione S-transferase that can be photolabeled with 5-azido-indole-3-acetic acid.
Previously, we identified a soluble protein from Hyoscyamus muticus that was photolabeled by 5-azido-indole-3-acetic acid. This protein was determined to be a glutathione S-transferase (GST; J. Bilang, H. Macdonald, P.J. King, and A. Sturm [1993] Plant Physiol 102: 29-34). We have examined the effect of auxin on the activity of this H. muticus GST. Auxins re
