1. Protein PEGylation for the design of biobetters: from reaction to purification processes
The covalent attachment of polyethylene glycol (PEG) to therapeutical proteins is an important route to develop biobetters for biomedical, biotech and pharmaceutical industries. PEG conjugation can shield antigenic epitopes of the protein, reduce degradation by proteolytic enzymes, enhance long-term stability and maintain or even improve pharmacokinetic and

2. An easy and efficient strategy for KEL genotyping in a multiethnic population
BACKGROUND: The Kell blood group system expresses high and low frequency antigens with the most important in relation to transfusion including the antithetic KEL1 and KEL2; KEL3 and KEL4; KEL6 and KEL7 antigens. Kell is a clinically relevant system, as it is highly immunogenic and anti-KEL antibodies are associated with hemolytic transfusion reactions and he

3. Heavy metal tolerance (Cr, Ag and Hg) in bacteria isolated from sewage
Samples of sewage from a university hospital and a chemistry technical school were analysed for the percentage of bacterial tolerance to chromium (Cr), silver (Ag) and mercury (Hg). Additionally, we investigated the effect of these metals on pigmentation and on some enzymatic activities of the metal tolerant strains isolated, as well as antimicrobial resista

4. Caracterização da função biológica da vitamina K biossintetizada pelas formas intraeritrocitárias de Plasmodium falciparum. / Analysis of the biological function of the vitamin K biosynthesized by intraerytrocytic forms of Plasmodium falciparum.
A falta de uma vacina eficaz e o problema da resistência aos fármacos têm dificultado o controle da malária. A busca de novos alvos biológicos para o desenvolvimento de antimaláricos eficazes tem se concentrado, em parte, na pesquisa e compreensão de vias metabólicas exclusivas do parasita. Nosso grupo vem investigando e caracterizando produtos da bi

5. Screening, selection, production and characterization of the enzyme xylanase from wild yeasts / Triagem, seleção, produção e caracterização da enzima xilanase a partir de leveduras silvestres
Endo-1,4-ß-xylanase (E.C. 3.2.1.8), commonly called xylanase, has great application in different types of industries such as feed, food, textiles, paper, ethanol from biomass, among others. These enzymes act in hydrolysis of the xylan, one of the most abundant polysaccharides found in the nature, present in cell plants linked to the hemicelullose. The main

6. HidrÃlise e oxidaÃÃo catalÃtica dos carboidratos do bagaÃo de cana-de-aÃÃcar em operaÃÃes descontÃnuas
In the local context, is clearly meet the need to enhance the sugarcane bagasse as biomass plant. Sugar cane bagasse is a waste coming from alcohol and sugar industries and available abundantly. This availability of sugarcane bagasse as raw material at low cost, combined with the feasibility of its recovery via chemical and biochemical processes, is the foun

7. Avaliação da técnica de eletrodiálise para a separação de ácido lactobiônico produzido por via biotecnológica
Glicose-fructose oxidoreductase (GFOR) and glicono-d-lactonase (GL) enzymes are present in Zymomonas mobilis bacteria cells. These enzymes are capable to catalyze lactobionic acid (AL) formation (or formation of its correspondent salts) together with sorbitol from lactose and fructose. Lactobionic acid and sodium lactobionate have important applications in m

8. Aplicação de lipases no tratamento de águas residuárias com elevados teores de lipídeos
The process of anaerobic digestion has been greatly developed during the last decades for the treatment of wastewater from food industries as for example, wastewaters from sugar and starch manufacturing and from breweries. However, for wastewaters which contain high amounts of fats and proteins, such as those from slaughterhouses and dairies, anaerobic diges

9. AVALIAÇÃO DE PROMOTORES DE CRESCIMENTO ALTERNATIVOS EM SUBSTITUIÇÃO AOS CONVENCIONAIS SOBRE O DESEMPENHO, CARACTERÍSTICAS DE CARCAÇA E MORFOMETRIA INTESTINAL EM FRANGOS DE CORTE / Evaluation of alternative growth promoters in order to substitute the conventionals on the performance, carcass yield and intestinal morphology of broilers
The experiment was conducted at the Laboratory of Poultry (LAVIC) of the Department of Animal Science at Federal University of Santa Maria - RS, from November of 2003 to January of 2004 aiming to evaluate the use of prebiotics, organic acids (acidifiers), enzymes and garlic (phytotherapeutic) as alternative growth promoters, instead of the conventionals (ant

10. Creatine kinase MB isoenzyme studies in diagnosis of myocardial infarction.
Serial measurements of the MB isoenzyme of creatine kinase, total creatine kinase, aspartate mainotransferase, and urea stable lactate dehydrogenase have been made in the serum of a series of 139 patients admitted with a diagnosis of suspected myocardial infarction. Serum MB isoenzyme measurements have also been made on postoperative surgical patients and pa

11. Enzyme exposure and enzyme sensitisation in the baking industry.
OBJECTIVES: To assess the exposure to enzymes and prevalence of enzyme sensitisation in the baking industry. METHODS: A cross sectional study was conducted in four bakeries, one flour mill, and one crispbread factory. Sensitisation to enzymes, flours, and storage mites was examined by skin prick and radioallergosorbent (RAST) tests. 365 workers were tested.

12. Average locus differences in mutability related to protein "class": a hypothesis.
Substantially less genetic variation has been recognized in studies of the proteins of nucleated cells by the technique of two-dimensional polyacrylamide gel electrophoresis than has been encountered in studies of serum transport proteins and erythrocyte enzymes with one-dimensional electrophoresis. Technical factors appear to account for only part of the di
