TL;DR: Four exopolysaccharides obtained from Botryosphaeria rhodina strains isolated from rotting tropical fruit grown on sucrose were purified on Sepharose CL-4B and indicated that each EPS existed in a triple-helix conformational state.

TL;DR: In this paper, a vision of the use of heterogeneous photocatalysis/electrochemically assisted degradation is discussed, and several operational parameters to achieve optimum efficiency of this photodegradation system are presented, such as the influence of temperature, applied potential, pH, initial dye concentration and choice of a UV source.
Abstract: TiO2 supported on ITO (indium tin oxide coated glass) was prepared and its photocatalytic activity was determined by photo-oxidation of commercial leather dye in aqueous solution illuminated with UV light. A vision of the use of the heterogeneous photocatalysis/electrochemically assisted degradation is discussed. Several operational parameters to achieve optimum efficiency of this photodegradation system are presented, such as the influence of temperature, applied potential, pH, initial dye concentration and choice of a UV source. The results indicate that the dye can be degraded totally and mineralized into inorganic products such as NH4+ ions. Decolorization ratios higher than 90% were observed during a period of 480 min. Relating the initial concentration with the approximate azo dye molar mass the formation of ≈96.79% NH4+ was calculated. FT-Raman and FT-IR spectroscopies indicated the influence the supporting electrolyte had on the process.

TL;DR: It is demonstrated that pets carry virulent DEC genes, which are mainly strains of EPECs and EAECs, and the presence of these virulence factors in isolates from animals without diarrhea suggests that pets can act as a reservoir for human infection.

TL;DR: In this paper, a regressao logistica was used to identify a prevalence of respiradores bucais in criancas de uma escola do ensino fundamental.
Abstract: Pretende-se identificar a prevalencia de respiradores bucais em criancas de uma escola do ensino fundamental. Foram aplicados 496 questionarios aos pais ou responsaveis das criancas de 1a a 4a serie de uma escola fundamental, para identificar respiradores bucais. O questionario incluia questoes sobre habitos, sono, comportamento, alimentacao, cuidados pessoais e respiracao. Para comparar as variaveis entre respiradores bucais e nasais, foi utilizado o teste de Mann-Whitney e qui-quadrado. Para medir o efeito da exposicao das variaveis explicativas sobre o desfecho primario, foi utilizada regressao logistica e sua magnitude foi calculada por meio do odds ratio. A significância estatistica foi estipulada em 5%. A taxa de devolucao dos questionarios foi de 84,5%. A prevalencia de respiracao bucal nessa populacao foi 56,8%. A mediana de idade foi sete anos (6-9). Nao houve diferenca estatisticamente significante entre os generos, 49,1% masculino e 50,9% feminino. O modelo final de regressao logistica identificou as variaveis baba, dorme bem (associacao negativa) e ronca como fatores que predizem a ocorrencia da respiracao bucal. A prevalencia de respiradores bucais foi semelhante a encontrada na literatura pesquisada. As variaveis babar, roncar e dormir bem (associacao negativa) podem predizer a ocorrencia da respiracao bucal.
