1. Enhanced serum interferon-lambda 1/interleukin-29 levels in patients with psoriasis vulgaris
Abstract Background: Interferon (IFN)-λ1, also named Interleukin (IL)-29, is a new member of the Type III IFN or IFN-λ family. IL-29 plays an important role in the pathogenesis of many types of autoimmune and inflammatory diseases. Objective: To study the role of IL-29 in the pathogenesis of psoriasis vulgaris. Methods: The authors detected the serum le

2. Biochemical and Molecular Mechanisms of Glucose Uptake Stimulated by Physical Exercise in Insulin Resistance State: Role of Inflammation
Resumo A obesidade associada à inflamação sistêmica induz resistência à insulina (RI), com consequente hiperglicemia crônica. Este processo envolve o aumento na liberação de citocinas pró-inflamatórias, ativação da enzima c-Jun N-terminal cinase (JNK), do fator nuclear kappa-B (NF-κB) e dos receptores do tipo Toll 4 (TLR4). Dentre as ferramenta

3. Estudo sobre a vida útil de rolamentos fixos de uma carreira de esferas. / Study about rolling bearing life of deep groove ball bearings.
O presente trabalho destina-se à discussão sobre o cálculo de vida útil de rolamentos. Mostrando o avanço do processo de cálculo ao longo das décadas até o mais alto grau de desenvolvimento atual. A preocupação do texto é demonstrar de forma simples e objetiva as divergências que existem entre a formulação teórica e a real vida dos rolamentos,

4. Adaptação do Inventário de Problemas de Fertilidade para homens e mulheres inférteis / Adaptation of the fertility problem inventory to infertile men and women.
The period between the investigation of infertility and the assisted-fertilization procedure (FA) has been characterized as responsible for chronic stress. Additionally, infertility alters the marital relationship and causes social and sexual transformations, and the couple may come to present depression and anxiety. To asses the infertile couple, the Fertil

5. COLORIMETRIA: PROPAGAÇÃO DOS ERROS E CÁLCULO DA INCERTEZA DE MEDIÇÃO NOS RESULTADOS ESPECTROFOTOMÉTRICOS / COLORIMETRY: PROPAGATION OF ERRORS AND UNCERTAINTY CALCULATIONS IN SPECTROPHOTOMETRIC MEASUREMENTS
Colorimetry - Propagation of Errors and Uncertainty Calculations in Spectrophotometric Measurements treats the measurement of the colour of objects, based on the measurement of spectral irradiance (self-luminous objects) or that of spectral reflectance or transmittance (opaque or transparent objects), followed by colorimetric calculations according to the CI

6. NUMERICAL STUDY OF LOSS OF INJECTIVITY IN ROCK / ESTUDO NUMÉRICO DE DECLÍNIO DE INJETIVIDADE EM ROCHA
Esta dissertação apresenta um estudo numérico, utilizando o método dos elementos finitos, para simular o entupimento de rochas provocado pela injeção de água contendo partículas sólidas. Dentre os diferentes parâmetros que afetam o declínio de injetividade, quatro foram analisados, considerando-se a situação de fluxo unidimensional: fator de dan

7. VERIFICAÇÃO DE MODELOS ANALÍTICOS PARA A PERDA DE INJETIVIDADE DE ROCHAS / ANALYTICAL STUDY OF THE INJECTIVITY LOSS OF ROCKS
This work deals with the impairment of rocks subjected to the injection of water with solid particles in suspension. The effect of the permeability reduction and consequent loss in rock injectivity is analyzed by the interpretation of core flow tests, previously reported, and simulated by using a computational program developed for this research. The program

8. An accessory role for Escherichia coli integration host factor: characterization of a lambda mutant dependent upon integration host factor for DNA packaging.
Bacteriophage lambda grows lytically on Escherichia coli defective for integration host factor, a protein involved in lambda site-specific recombination and the regulation of gene expression. We report the characterization of a mutant, lambda cos154, that, unlike wild-type lambda, is defective for growth in integration host factor-defective E. coli. The cis-

9. Isolation of the Bacteriophage Lambda Receptor from Escherichia coli
A factor which inactivates the phage lambda can be extracted from Escherichia coli. This factor is a protein and is located in the outer membrane of the bacterial envelope. It is found in extracts of strains which are sensitive to phage lambda, but not in extracts of strains specifically resistant to this phage. We conclude that this factor is the lambda rec

10. Plasmid-Controlled Variation in the Content of Methylated Bases in Bacteriophage Lambda Deoxyribonucleic Acid
The N6-methyladenine (MeAde) and 5-methylcytosine (MeC) contents in deoxyribonucleic acid (DNA) of bacteriophage lambda has been analyzed as a function of host specificity. The following facts have emerged: (i) lambda grown on strains harboring the P1 prophage contain ca. 70 more MeAde residues/DNA molecule than lambda grown either in the P1-sensitive parent

11. Transposition of R factor genes to bacteriophage lambda.
Transpositions of segments of R factor (antibiotic resistance plasmids) to bacteriophage lambda have been selected and characterized. Cells of Escherichia coli harboring R factors that determine kanamycin resistance were infected with phage lambda, and lambdakan transducing lines were obtained. Each of the three examined is unusual when compared to lambda tr

12. Identification of USF as the ubiquitous murine factor that binds to and stimulates transcription from the immunoglobulin lambda 2-chain promoter.
To study the specificity and identity of NF-lambda 2, a ubiquitous murine nuclear factor that interacts specifically with the promoter of the lambda 2-chain gene and stimulates its transcription, competition experiments were carried out using DNA fragments from various immunoglobulin regulatory elements. The results showed that a fragment containing the H-ch
