1. Optimization and characterization of alkaline protease and carboxymethyl-cellulase produced by Bacillus pumillus grown on Ficus nitida wastes
The potentiality of 23 bacterial isolates to produce alkaline protease and carboxymethyl-cellulase (CMCase) on Ficus nitida wastes was investigated. Bacillus pumillus ATCC7061 was selected as the most potent bacterial strain for the production of both enzymes. It was found that the optimum production of protease and CMCase were recorded at 30 °C, 5% Ficus n

2. A Boophilus microplus vitellin-degrading cysteine endopeptidase
Here we describe the purification and characterization of a vitellin (VT) degrading cysteine endopeptidase (VTDCE) from eggs of the hard tick Boophilus microplus. A homogeneous enzyme preparation was obtained by chromatographic fractionation on ion-exchange and gel filtration columns and an autolysis step. This step consisted of incubation of a semipurified

3. Effect of antioxidants on stallion spermatozoa under heat stress / Efeito de antioxidantes aos espermatozoides de equinos submetidos ao estresse térmico
A avaliação da eficácia reprodutiva do garanhão e do sêmen resfriado e⁄ou congelado é de fundamental importância na prática reprodutiva dos eqüinos. Predizer a fertilidade de um garanhão constitui uma decisão subjetiva. O presente estudo foi realizado com o objetivo de testar diferentes técnicas de coloração, assim como testes que avaliem

4. Avaliação de características nutricionais da mandioca e de seus híbridos interespecíficos
Cassava (Manihot esculenta Crantz) is one of the most important staple crops of the tropics and subtropics, feeding more than 800 million of people around the world. The roots of the common cultivars are extremely rich in starch, but are poor in other nutrients, such as protein, amino acids and micronutrients. It is reported that the contents of these nutrie

5. Caracterização de dois cDNAs homológos e uma AP endonuclease em cana-de-açúcar
The genome of all organisms is subject to injuries that can be caused by endogenous and environmental factors. If these lesions are not corrected, it can be fixed generating a mutation which can be lethal to the organisms. In order to prevent this, there are different DNA repair mechanisms. These mechanisms are well known in bacteria, yeast, human, but not i

6. Association between polymorphisms in genes related to glutathione metabolism and susceptibility to microvascular complications in type 1 diabetes mellitus / Estudo da associação entre polimorfismo em genes relacionados ao metabolismo da glutationa e a suscetibilidade a complicações microvasculares no diabete melito tipo 1
INTRODUÇÃO: acredita-se que o controle glicêmico inadequado, a duração do diabetes melito (DM) e a presença de hipertensão arterial e dislipidemia sejam os fatores de risco mais importantes para o desenvolvimento das complicações microvasculares no DM, contudo, existem inúmeras evidências sugerindo que uma predisposição genética participe da su

7. Expressão temporal e espacial de RECK, metaloproteinase-2 e metaloproteinase-9 durante a palatogenese em camundongos / Temporal and spatial expression of RECK, metalloproteinase-2 and metalloproteinase-9 during palatogenesis in mice
The oral clefts show a great influence in the size of their hosts. They have, since birthy, difficulties in alimentation, problems in the maxilar bones, in dental arch, in speech, and in some cases, in hearing. In addition, the hosts and their families have serious psychological problems due to the esthetic lenght caused by anomalia. With no doubt, the forma

8. Identificação de genes potencialmente envolvidos na interação tomateiro - Potyvirus / Identification of genes potentially involved in the interaction tomato - Potyvirus
During co-evolution between virus and host, a complex interaction has been developed involving several mechanisms of pathogen attack and host defense. Host defense responses cause up- and downward shifts in gene expression. However, the effects of viral infection in the hosts gene expression profile are still poorly understood. With the objective of identify

9. AvaliaÃÃo da toxicidade tecidual de Melxi e bromelina por via oral em ratos
ÂCrude bromelain, an aqueous extract from pineapples, has been sold in health food stores as a nutritional supplement for âdigestive aidâ. It contains a mixture of different proteins, carbohydrates and other components. Cystein proteinases in crude bromelain are called bromelains, they are stem bromelain (EC 3.4.22.32), comosain, ananain (EC 3.4.22.31)

10. Fungos microaerobios na bioconversão de material lignocelulosico
Cellulose accounts for the major part of lignocellulose found in nature, and consequently, its degradation is essential for the operation of the global carbon cycle. Lignocellulose, such as wood, is mainly composed of a mixture of cellulose (40%), hemicellulose (20-30%), and lignin (15-30%). An association of enzymes acting in a concerted fashion degrades ce

11. Produção de [beta]-1,3 glucanases, proteases liticas e quitinases por microrganismos e aplicação na lise de leveduras
The aim of this work was the study of b-1,3 glucanases, proteases and chitinases production by B1, B22, B26, FXX, Oerskovia sp. nO4 and Cellulomonas cartae nº191 strains in culture media containing differents inductors as well as their application on yeast cell lysis. The strains B26 and Cellulomonas cartae nO191 showed highest protease production using the

12. "Caracterização do Efeito da Jacaragina sobre a Produção e Liberação de Citocinas Pró-inflamatórias em Modelo Murino". / Effect of jararhagin on the production and release of pro-inflammatory cytokies in a murine model.
The inflammatory effect of jararhagin, a haemorrhagic toxin from Bothrops jararaca venom, was evaluated in an in vitro (Murine Peritoneal Adherent Cells-MPACs) and in vivo system (mouse footpad), through the production of TNF-a, IL-1b and IL-6 mRNA (RT-PCR) and the release of these cytokines in the culture supernatant and locally at the site of injection (EL
