1. REPARAÇÃO DE α-ACETILOXI-N-CICLOEXILAMIDAS ATRAVÉS DA REAÇÃO DE PASSERINI UTILIZANDO DIMETILCARBONATO COMO SOLVENTE AMBIENTALMENTE AMIGÁVEL
A series of α-acetyloxy-N-cyclohexylamides was efficiently obtained via Passerini reaction of cyclohexyl isocyanide, acetic acid, and different aromatic and aliphatic aldehydes using refluxing dichloromethane or dimethylcarbonate (DMC). Reactions performed with DMC led to desired products in moderate to good yields, corroborating this solvent as a eco-frien

2. DETECTION OF INTESTINAL PARASITES IN THE ENVIRONMENTS OF A PUBLIC SCHOOL IN THE TOWN OF DIAMANTINA , MINAS GERAIS STATE, BRAZIL
SUMMARY Intestinal parasites are a major public health problem in developing countries, most prevalent in areas where sanitation is poor and the population's hygiene is inadequate. They affect people of all ages, although school-age children are the most susceptible. In this study, we investigated the presence of intestinal parasites in the shared environmen

3. Resistance of oxidative stress in biofilm and planktonic cells
This work studied the susceptibility of biofilm produced by E. coli to oxidative stress, and compared the components of free radicals defences: level of glutathione, catalase and dismutase activities in planktonic and biofilm located cells. Results showed the diversity of responses to oxidative stress in bacterial cells in log or stationary phases in both pl

4. Adherence and virulence genes of Escherichia colifrom children diarrhoea in the Brazilian Amazon
The bacterial pathogen most commonly associated with endemic forms of childhood diarrhoea is Escherichia coli. Studies of epidemiological characteristics of HEp-2 cell-adherent E. coli in diarrhoeal disease are required, particularly in developing countries. The aim of this study was evaluate the presence and significance of adherent Escherichia coli from di

5. Relationship among Shigella spp. and enteroinvasive Escherichia coli (EIEC) and their differentiation
Shigellosis produces inflammatory reactions and ulceration on the intestinal epithelium followed by bloody or mucoid diarrhea. It is caused by enteroinvasive E. coli (EIEC) as well as any species of the genus Shigella, namely, S. dysenteriae, S. flexneri, S. boydii, and S. sonnei. This current species designation of Shigella does not specify genetic similari

6. Inflammatory response of endothelial cells to hepatitis C virus recombinant envelope glycoprotein 2 protein exposure
The hepatitis C virus (HCV) encodes approximately 10 different structural and non-structural proteins, including the envelope glycoprotein 2 (E2). HCV proteins, especially the envelope proteins, bind to cell receptors and can damage tissues. Endothelial inflammation is the most important determinant of fibrosis progression and, consequently, cirrhosis. The a

7. Microbiological aspects of the biofilm on wooden utensils used to make a Brazilian artisanal cheese
The artisanal Minas cheese is produced from raw cow's milk and wooden utensils were employed in its manufacture, which were replaced by other materials at the request of local laws. This substitution caused changes in the traditional characteristics of cheese. Due to the absence of scientific studies indicating the microbial composition of biofilms formed on

8. Effect of sub-minimum inhibitory concentrations of ciprofloxacin, amikacin and colistin on biofilm formation and virulence factors of Escherichia coli planktonic and biofilm forms isolated from human urine
The aim of this study was to determine the effect of subinhibitory concentrations (sub-MICs) of ciprofloxacin, amikacin and colistin on biofilm formation, motility, curli fimbriae formation by planktonic and biofilm cells of E. coli strains isolated from the urine of patients with various urinary system infections. Quantification of biofilm formation was car

9. In vitro culture and characterization of alveolar bone osteoblasts isolated from type 2 diabetics
In order to understand the mechanisms of poor osseointegration following dental implants in type 2 diabetics, it is important to study the biological properties of alveolar bone osteoblasts isolated from these patients. We collected alveolar bone chips under aseptic conditions and cultured them in vitro using the tissue explants adherent method. The biologic

10. Caracterização de cepas de Escherichia coli contendo diferentes alelos rpoS. / Characterization of Escherichia coli strains carrying different rpos alleles.
Escherichia coli can be found in many different habitats and has to be prepared to survive and grow under unfavorable conditions. Bacteria adaptation to different growth conditions requires an efficient control of gene expression. One of the primary forms of gene expression control is the competition between different sigma factors for the binding to the cor

11. 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

12. Desenvolvimento analítico e farmacotécnico de formas farmacêuticas sólidas de isoflavona de soja / Pharmaceutics and analytical development of solid dosage forms of soy isoflavones
Isoflavonas são flavonóides encontrados em abundância nos grãos de soja (Glycine max L.). Essas substâncias têm estrutura semelhante ao estrógeno e possuem uma ação fracamente estrogênica. São utilizadas no tratamento dos sintomas da menopausa como alternativa às terapias de reposição hormonal convencionais, por provocarem menor número de efei
