1. Parâmetros genéticos para características de prolificidade nas raças Landrace e Large White
Dados de suínos das raças Landrace (LD) e Large White (LW) foram utilizados para estimar componentes de variância para número total de leitões nascidos (NTN), nascidos vivos (NV) e de leitões vivos ao quinto dia (LV5). Usou-se o método da máxima verossimilhança restrita (REML) para estimar componentes de variância. O modelo misto incluiu os efeitos

2. Análise empírica da curva de juros real brasileira: uma aplicação prática na tomada de decisão de carteira de renda fixa
Um dos grandes desafios na gestão de uma carteira de renda fixa passa pela estimação da curva de juros dos títulos que a compõe. Sua correta estimação e a identificação dos fatores de risco associados a estes títulos são imprescindíveis para uma boa gestão de uma carteira de renda fixa, assim como para o correto apreçamento dos ativos. O presen

3. Implict taxes: the reduction in pre-tax returns on tax-favored assets / Tributação implícita: redução da taxa de retorno pré-imposto em ativos favoravelmente tributados
Tributos implícitos refletem a extensão pela qual ativos favorecidos tributariamente têm seu retorno pré-imposto reduzido em comparação com o retorno pré-imposto de ativos sem benefício fiscal e de risco similar. Em condição de equilíbrio de mercado, se dois ativos de riscos semelhantes possuírem o mesmo fluxo de caixa pré-imposto, mas um deles

4. O pólo inferior do baço de ratos e a oxigenoterapia hiperbárica
OBJETIVO: Estudar aspectos funcionais e morfológicos do pólo inferior do baço de ratos tratados ou não com oxigênio hiperbárico no pós-operatório. MÉTODOS: Foram operados 79 ratos, Wistar, pesando 248,7g ± 27 , distribuídos em dois grupos: A - Simulação (n= 40), B - pólo inferior (n=39), e divididos em dois subgrupos: 11 e 70 dias. Cada subgrup

5. ntn Genes Determining the Early Steps in the Divergent Catabolism of 4-Nitrotoluene and Toluene in Pseudomonas sp. Strain TW3
Pseudomonas sp. strain TW3 is able to oxidatively metabolize 4-nitrotoluene and toluene via a route analogous to the upper pathway of the TOL plasmids. We report the sequence and organization of five genes, ntnWCMAB*, which are very similar to and in the same order as the xyl operon of TOL plasmid pWW0 and present evidence that they encode enzymes which are

6. Fetal and neoplastic expression of the neurotensin gene in the human colon.
OBJECTIVE: The authors identified various colon cancers that express the gene for the gut peptide neurotensin (NT/N). In addition, the authors sought to delineate the temporal pattern of NT/N gene expression in the human fetal colon. SUMMARY BACKGROUND DATA: Expression of NT/N is localized to the mucosa of the adult small bowel but also has been identified i

7. The neurotensin gene is a downstream target for Ras activation.
Ras regulates novel patterns of gene expression and the differentiation of various eukaryotic cell types. Stable transfection of Ha-ras into the human colon cancer line CaCo2 results in the morphologic differentiation to a small bowel phenotype. The purpose of our study was to determine whether the Ras regulatory pathway plays a role in the expression of the

8. Characterization of promoter elements required for cell-specific expression of the neurotensin/neuromedin N gene in a human endocrine cell line.
Expression of the gene encoding neurotensin/neuromedin N (NT/N) is mostly limited to the brain and specialized enteroendocrine cells (N cells) of the distal small intestine. We have analyzed the NT/N DNA sequences upstream of the RNA start site that direct cell-specific expression using a novel human endocrine cell line, BON, that resembles intestinal N cell

9. Cloning and Expression of ntnD, Encoding a Novel NAD(P)+-Independent 4-Nitrobenzyl Alcohol Dehydrogenase from Pseudomonas sp. Strain TW3
Pseudomonas sp. strain TW3 is able to metabolize 4-nitrotoluene to 4-nitrobenzoate and toluene to benzoate aerobically via a route analogous to the upper pathway of the TOL plasmids. We report the cloning and characterization of a benzyl alcohol dehydrogenase gene (ntnD) which encodes the enzyme for the catabolism of 4-nitrobenzyl alcohol and benzyl alcohol

10. Developmental expression of the neurotensin gene in the rat liver.
OBJECTIVE: This study determined whether the neurotensin gene is expressed during early development of the liver. SUMMARY BACKGROUND DATA: Neurotensin (NT), a gut tridecapeptide localized mainly to the distal small bowel and brain of adults, is an important hormone regulating gut motility, secretion and mucosal growth. Expression of NT peptide and the gene i

11. Neurotensin expression and release in human colon cancers.
Neurotensin (NT), a distal gut peptide released by intraluminal fats, is trophic for normal small bowel and colonic mucosa. In addition, NT stimulates growth of certain colon cancers; the mechanism for this effect is not known. The purpose of this study was to determine whether human colon cancers (HCC) (1) express the mRNA for NT/neuromedin N (N), (2) produ

12. Selection of Specific Endophytic Bacterial Genotypes by Plants in Response to Soil Contamination
Plant-bacterial combinations can increase contaminant degradation in the rhizosphere, but the role played by indigenous root-associated bacteria during plant growth in contaminated soils is unclear. The purpose of this study was to determine if plants had the ability to selectively enhance the prevalence of endophytes containing pollutant catabolic genes in
