1. Cloning, sequence analysis, and expression of cDNA coding for the major house dust mite allergen, Der f 1, in Escherichia coli
Our objective was to clone, express and characterize adult Dermatophagoides farinae group 1 (Der f 1) allergens to further produce recombinant allergens for future clinical applications in order to eliminate side reactions from crude extracts of mites. Based on GenBank data, we designed primers and amplified the cDNA fragment coding for Der f 1 by nested-PCR

2. Contributions to the search methods of optimum trellis codes on new lattices partitioning / Contribuições aos metodos de procura dos codigos de treliça otimos sobre novas partições de reticulados
This thesis presents some contributions to the coded modulation schemes for the trellis codes based on lattices partitioning. One of the main contributions is the construction of the trellis codes based on novel lattices partitioning and also on chains partitioning. In order to optimize the search for the optimum trellis codes, a search algorithm was propose

3. Sistema de codificação de video baseado em transformadas tridimensionais, rapidas e progressivas / Video coding system based on three dimensional, fast and progressive transforms
The research on video coding systems has always been looking for techniques that can reach the highest possible compression rate. This compression rate increase is generally achieved by means of increased coding complexity, which is supported by the continuous increase verified in computational power. However, in some video coding and transmission situations

4. From binary codes to lattices and spherical codes / De codigos binarios a reticulados e codigos esfericos
In this work it is presented through examples a connection between inary codes, lattices and spherical codes. A brief introduction to coding theory, properties and examples is included in the first chapter. In Chapter 2 lattices are approached with focus on the quotient of lattices, graphs on flat tori and connections with circulant graphs. An introduction t

5. Regions of the polyoma genome coding for T antigens.
The early region of the polyoma genome encodes three T antigens. We have analyzed the organization of the coding regions for the T antigens, using the nucleotide sequence of polyoma DNA and peptides derived from purified, radio-labeled T antigens, separated by two-dimensional electrophoresis and chromatography. We compared the peptides, predicted from the nu

6. Protein Coding Palindromes Are a Unique but Recurrent Feature in Rickettsia
Rickettsia are unique in inserting in-frame a number of palindromic sequences within protein coding regions. In this study, we extensively analyzed repeated sequences in the genome of Rickettsia conorii and examined their locations in regard to coding versus noncoding regions. We identified 656 interspersed repeated sequences classified into 10 distinct fami

7. Evolutionary self-organization of cell-free genetic coding
Genetic encoding provides a generic construction scheme for biomolecular functions. This paper addresses the key problem of coevolution and exploitation of the multiple components necessary to implement a replicable genetic encoding scheme. Extending earlier results on multicomponent replication, the necessity of spatial structure for the evolutionary stabil

8. Frog Virus 3 Replication: Analysis of Structural and Nonstructural Polypeptides in Infected BHK Cells by Acidic and Basic Two-Dimensional Gel Electrophoresis
Analysis of frog virus 3-infected BHK cells by two-dimensional, acidic and basic gel electrophoresis showed that at least 90 infected cell-specific polypeptides could be detected. These polypeptides represent between 70 and 85% of the coding capacity of the viral genome. The polypeptides were sequentially induced in at least three phases. The virus gradually

9. Sequence of the bacteriophage SP01 gene coding for transcription factor 1, a viral homologue of the bacterial type II DNA-binding proteins.
The Bacillus subtilis phage SP01, whose DNA contains 5-hydroxymethyluracil (hmUra) in place of thymine, codes for an abundant, small, basic protein called TF1. TF1 binds preferentially to hydroxymethyluracil-containing DNA and thereby selectively inhibits transcription of such DNA in vitro. The gene for TF1 has been sequenced. We find that this viral protein

10. An Integrated Sequence-Structure Database incorporating matching mRNA sequence, amino acid sequence and protein three-dimensional structure data.
We have constructed a non-homologous database, termed the Integrated Sequence-Structure Database (ISSD) which comprises the coding sequences of genes, amino acid sequences of the corresponding proteins, their secondary structure and straight phi,psi angles assignments, and polypeptide backbone coordinates. Each protein entry in the database holds the alignme

11. Characterization of the gene encoding the hemocyanin subunit e from the tarantula Eurypelma californicum.
The gene for the hemocyanin subunit e of the tarantula Eurypelma californicum has been isolated from a genomic phage library by using a corresponding cDNA clone as a probe. The transcriptional unit spans a chromosomal region of about 55 kilobase pairs (kbp). The gene consists of nine exons that are separated by large introns. The intron/exon boundaries were

12. Regulation of polypeptide synthesis during Caulobacter development: two-dimensional gel analysis.
The gram-negative bacterium Caulobacter crescentus progresses through three distinct morphological transitions, including both motile and nonmotile cell types, during its cell cycle. Assessment of the extent of regulation of polypeptide synthesis during these transitions was carried out with two-dimensional gel electrophoresis of whole-cell extracts. Synchro
