1. DURABILIDADE DO CONCRETO COM CINZA DE CASCA DE ARROZ NATURAL SEM MOAGEM: MITIGAÇÃO DA REAÇÃO ÁLCALI-SÍLICA E PENETRAÇÃO DE CLORETOS / DURABILITY OF CONCRETE WITH NATURAL RICE HUSK ASH WITHOUT GRINDING: MITIGATION OF ALKALI-SILICA REACTION AND CHLORIDE PENETRATION
O emprego de cinza de casca de arroz (CCA) natural no concreto visa contribuir para a sustentabilidade da construção civil, destinando de maneira adequada, esse material que antes seria considerado um resíduo poluente. Porém, é necessária a investigação das consequências em substituir parte do cimento por CCA natural para produzir concreto com final

2. Study of expression of proteins Metalotioneína, NFkB, Ciclina D1 and Cdk4 in cell lines derived from human squamous cell carcinoma / Estudo da expressão das proteínas metalotioneína, NFkB, ciclina D1 e Cdk4 em linhagens celulares derivadas de carcinoma epidermóide humano
O carcinoma epidermóide por se tratar de uma doença genética, apresenta dificuldades em relação ao seu tratamento. As vias de sinalização celular por controlarem os mecanismos responsáveis pela proliferação e sobrevivência da célula, são de extrema importância nos estudos da biologia do câncer e oncogênese. Aberrações cromossômicas que afe

3. anÃlise in silico deEST-SSR em phaseolus vulgaris e Glycine max e transferibilidade de marcadores para Vigna unguiculata
Expressed Sequence Tags (EST) database is a valuable source of information for molecular markers development. In the present work, simple sequence repeats (SSR) have been detected in Phaseolus vulgaris and Glycine max ESTs, aiming the development of ESTSSR markers for cowpea (Vigna unguiculata) improvement. A total of 10,880 common bean ESTs and 116,965 soy

4. Avaliação in vitro da expressão das proteínas PTEN, Akt, Mdm2 e p53 em células de carcinoma epidermóide de cabeça e pescoço submetidas a ação de EGF e 17-AAG / In vitro evaluation of the expression of PTEN protein, Akt, Mdm2 and p53 in cells of squamous cell carcinoma of head and neck under the action of EGF and 17-AAG
O carcinoma epidermóide de cabeça e pescoço é responsável por 90% das neoplasias malignas, nesta região. Molecularmente, inúmeras vias de sinalização, ainda não muito bem compreendidas, são responsáveis pelo seu crescimento e invasão para tecidos vizinhos, além de metástases para órgãos distantes. Este trabalho destinou-se a avaliar o crosst

5. CaracterizaÃÃo cromossÃmica de hÃbridos intergenÃricos de trigo (Triticum aestivum X Thinopyrum ponticum) com diferentes combinaÃÃes genÃmicas
Foram caracterizados citogeneticamente oito acessos, incluindo a linhagem de trigo PF 839197 (Triticum aestivum, 2n = 42), Thinopyrum ponticum PF Ag. el. 84001 (2n = 70) e seis acessos hÃbridos derivados de PF 839197/PF Ag. el. 84001//2*âCEP19â, com cinco ou sete geraÃÃes de autofecundaÃÃo. Cromossomos de PF 839197 e de Ag. el. 84001 foram analisados

6. KU135, a Novel Novobiocin-Derived C-Terminal Inhibitor of the 90-kDa Heat Shock Protein, Exerts Potent Antiproliferative Effects in Human Leukemic Cells
The 90-kDa heat shock protein (Hsp90) assists in the proper folding of numerous mutated or overexpressed signal transduction proteins that are involved in cancer. Consequently, there is considerable interest in developing chemotherapeutic drugs that specifically disrupt the function of Hsp90. Here, we investigated the extent to which a novel novobiocin-deriv

7. Nm23-H1 Metastasis Suppressor Expression Level Influences the Binding Properties, Stability, and Function of the Kinase Suppressor of Ras1 (KSR1) Erk Scaffold in Breast Carcinoma Cells
Metastatic disease is a significant contributor to cancer patient mortality. We previously reported that the Kinase Suppressor of Ras1 (KSR1) scaffold protein for the Erk mitogen-activated protein kinase pathway coimmunoprecipitated the metastasis suppressor protein Nm23-H1. We now hypothesize that altered expression levels of Nm23-H1 influence the binding p

8. beta 0 thalassemia, a nonsense mutation in man.
We determined the complete nucleotide sequence of the 5' noncoding region and the first 74 amino acids of the nonfunctional beta-globin mRNA in a patient with homozygous beta 0 thalassemia. We identified the molecular defect as a single nucleotide substitution in the coding region of the mRNA. At the position corresponding to amino acid 17, replacement of an

9. The two zinc finger-like domains of GATA-1 have different DNA binding specificities.
The GATA-1 transcription factor has been shown to be important in the regulation of globin and non-globin genes in erythroid, megakaryocytic and mast cell lineages. It is a member of a family of GATA proteins which both overlap in their expression patterns and bind the motif (A/T)GATA(A/G). The GATA family of proteins are also members of the superfamily of z

10. Circulating antibodies to Saccharomyces cerevisiae (bakers'/brewers' yeast) in gastrointestinal disease.
AIM: To measure circulating antibodies to yeast organisms that could be used to characterise the yeast specific immune response in gastrointestinal disease. METHODS: A quantitative, isotype specific enzyme linked immunosorbent assay was developed to measure circulating antibodies to an aqueous extract of Saccharomyces cerevisiae (sacc). Comparisons of specif

11. Splicing mutations in the CHO DHFR gene preferentially induced by (+/-)-3 alpha,4 beta-dihydroxy-1 alpha,2 alpha-epoxy-1,2,3,4- tetrahydrobenzo[c]phenanthrene.
Cultured Chinese hamster ovary (CHO) cells were treated with the polycyclic aromatic hydrocarbon racemic 3 alpha,4 beta-dihydroxy-1 alpha,2 alpha-epoxy-1,2,3,4- tetrahydrobenzo[c]phenanthrene. Mutants deficient in dihydrofolate reductase activity were isolated. A carcinogen treatment at 0.1 microM yielded at 46% survival of the treated population and an indu
