1. Um estudo sobre propriedades do paralelogramo envolvendo o processo de argumentação e prova
O presente trabalho, vinculado ao projeto AprovaME, desenvolvido na Pontifícia Universidade Católica de São Paulo, tem por objetivo verificar os avanços e as dificuldades apresentadas pelos alunos na elaboração de provas sobre as propriedades dos paralelogramos. Os procedimentos dessa pesquisa foram fundamentados nas teorias de Parzysz (2001) sobre pro

2. Termos de consentimento livre e esclarecido: o gênero e sua estruturação
The goal of this work is to analyze Informed Consent texts (TCLE), used at the referring of research projects to Ethics Committees evaluations, concerning to the Resolution 196/96. This kind of study is relevant because of the research communitys necessity to elaborate those texts in a clear and cohesive way, so that people are able to understand them. To th

3. Use of Genome Selected Repeated Sequences Increases the Sensitivity of PCR Detection of Tropheryma whipplei
The availability of the Tropheryma whipplei genome offers the putative possibility of choosing logical DNA targets. We applied a PCR assay (targeting repeated sequences of T. whipplei) to samples from patients with Whipple's disease and to those from members of a control group. When compared to the results seen with regular PCR, the sensitivity of repeat PCR

4. Polymorphisms on the right arm of yeast chromosome III associated with Ty transposition and recombination events.
The region of Saccharomyces cerevisiae chromosome III centromere-distal to the PGK gene is the site of frequent chromosome polymorphisms. We have sequenced this region from fragments of chromosome III isolated from three different yeast strains, GRF88, CN31C and CF4-16B. The sequence analysis demonstrates that these polymorphisms are associated with the pres

5. Proposed Standardization of Neisseria meningitidis PorA Variable-Region Typing Nomenclature
Neisseria meningitidis isolates are conventionally classified by serosubtyping, which characterizes the reactivities of the PorA outer membrane protein variable-region (VR) epitopes with monoclonal antibodies (MAbs). A newer method (PorA VR typing) uses predicted amino acid sequences derived from DNA sequence analysis. The resulting classification schemes ar

6. A systematic approach to reconstructing transcription networks in Saccharomyces cerevisiae
Decomposing regulatory networks into functional modules is a first step toward deciphering the logical structure of complex networks. We propose a systematic approach to reconstructing transcription modules (defined by a transcription factor and its target genes) and identifying conditions/perturbations under which a particular transcription module is activa

7. Sequence evolution and copy number of Ty1-copia retrotransposons in diverse plant genomes
Sequence evolution of the reverse transcriptase (RT) gene in retrotransposons belonging to the Ty1-copia class was studied in 11 plant species. Phylogenetic reconstruction of the evolutionary history of RT sequences indicated a strong pattern of purifying selection, manifested as high ratios of third to first plus second codon position substitutions, an

8. ELM server: a new resource for investigating short functional sites in modular eukaryotic proteins
Multidomain proteins predominate in eukaryotic proteomes. Individual functions assigned to different sequence segments combine to create a complex function for the whole protein. While on-line resources are available for revealing globular domains in sequences, there has hitherto been no comprehensive collection of small functional sites/motifs comparable to

9. Nucleotide excision repair affects the stability of long transcribed (CTG*CAG) tracts in an orientation-dependent manner in Escherichia coli.
The influence of nucleotide excision repair (NER), the principal in vivo repair system for DNA damages, was investigated in Escherichia coli with uvrA, uvrB and uvrAuvrB mutants with the triplet repeat sequences (TRS) involved in myotonic dystrophy, the fragile X syndrome and Friedreich's ataxia. (CTG*CAG)175was more stable when the (CTG) strand was transcri

10. SCORE: A computational approach to the identification of cis-regulatory modules and target genes in whole-genome sequence data
A large fraction of the information content of metazoan genomes resides in the transcriptional and posttranscriptional cis-regulatory elements that collectively provide the blueprint for using the protein-coding capacity of the DNA, thus guiding the development and physiology of the entire organism. As successive whole-genome sequencing projects—–includi
