Synergistic effect of fluoride and sodium hexametaphosphate in toothpaste on enamel demineralization in situ

To evaluate the effect of a fluoride dentifrice containing sodium hexametaphosphate (HMP) on enamel demineralization in situ. This double-blind and cross-over study consisted of 3 phases (7 days each) in which 12 volunteers wore intraoral appliances containing four enamel bovine blocks. Specimens were treated (3×/day) with placebo (no F or HMP), 1100ppm F (1100F) and 1100F plus HMP1% (1100F-HMP1%) toothpastes, and the cariogenic challenge was performed using a 30% sucrose solution (6×/day). Final surface hardness, the percentage of surface hardness loss (%SH), the integrated loss of subsurface hardness (ΔKHN), as well as enamel calcium (Ca), phosphorus (P) and firmly-bound fluoride (F) were determined. Also, biofilm formed on the blocks were analyzed for F, Ca, P and insoluble extracellular polysaccharide (EPS) concentrations. Data were submitted 1-way ANOVA, followed by Student-Newman-Keuls' test (p<0.05). 1100F-HMP1% promoted the lowest %SH and ΔKHN among all groups (p<0.001). The addition of HMP1% to 1100F did not enhance enamel F uptake, but significantly increased enamel Ca concentrations (p<0.001). Similar EPS concentrations were seen for 1100F-HMP1% and 1100F groups (p>0.05). All the groups were supersaturated with respect to HA. However, only 1100F-HMP1% group was supersaturated with respect to CaF2 (p<0.05). The ionic activities of F(-), CaF(+) and HF(0) for the 1100F-HMP1% group were the highest among all groups (p<0.001). The addition of HMP1% to a conventional toothpaste significantly reduces enamel demineralization in situ when compared to 1100F. This dentifrice could be a viable alternative to patients at high risk of caries.

Ocorrência de Clostridium botulinum tipos C e D em criatórios de bovinos no município de Cocalinho, Vale do Araguaia, Mato Grosso

In order to assess the occurrence and distribution of spores and toxins of Clostridium botulinum types C and D in three farms in Cocalinho, at the Araguaia River valley, State of Mato Grosso, Brazil, we analyzed sediment samples from 40 water holes, soil and cattle feces, collected around water holes. Sediments were analyzed by direct method, whilst feces, soil and also sediment samples were individually analyzed by indirect method. The detection of spores and botulinum toxins in the filtered material was performed by bioassay in Swiss Webster mice strain, as well as the serum-neutralization of the positive materials for typing. Samples of cattle feces showed the largest positive rate for C. botulinum, with 25/40 (62.5%), followed by soil, 12/40 (30%), and by sediment, 13/40 (32.5%). From the 40 cattle feces samples, 25 (62.00%) were positive for Clostridium botulinum; six samples were identified as type C, other six as type D, and 13 samples were classified as CD complex. From the equal number (40) of soil samples, 12 (30%) were positive for C. botulinum; two samples were identified as type C, other three as type D, and seven samples were classified as CD complex. Regarding the 40 sediment samples, 13 (32.5%) were positive for C. botulinum; two samples were identified as type C, other three as type D, and eight samples were classified as CD complex. No botulism toxin was detected by indirect method.

Adaptação da produção aos objetivos de competitividade e produtividade: a pesquisa-ação em uma manufatureira de cutelaria inserida em rede

One of the oldest segments in operations management, whose models are always subject to development efforts, for academics and productive organizations, is the management of production and work organization. Proposals for strategic management principles that seek to bring production to streamline processes reduce costs and add value, identifying problems with material flow and information while reducing the response time. This is realized through the pursuit of the best actions to achieve goals and targets established in a successful Planning and Production Control. This article aims to identify and implement actions that increase the speed of supply of goods produced in a enterprise cutlery; positively influencing the perception of customers. Such attitudes benefit all actors involved in the network, a fact which is expressed in the production chain. To lay the foundations of research and validate the data obtained, it was a study drawing on action research methodology. The goods produced are sold, mainly to wholesalers. Was proved seven aspects to improve and enhance the competitiveness of the organization, among them the complete design of the network, integrating upstream and downstream actors.

Camões revisitado: sobre que farei com este livro? de José Saramago

The objective of this work is to analyze the literary construction of Camões in the work Que farei com este livro?, by José Saramago. By difficulty in publishing his magnum opus, Os Lusíadas, Camões traverses the various Portuguese authorities in order to be able to give concreteness to his work years in exile. Using historical aspects and gaps on the biography of Camões, Saramago creates a work that shows the inertia that reigned in Portugal after the great conquests. Work of counterpoint between past and present, Que farei com este livro? represents an important reflection on the role of the writer and their challenges in times of decadence.

O processo de verticalização na cidade de São José dos Campos - SP e sua arquitetura no período de 1960 a 2010

From the second half of the twentieth century, due to several factors that have attracted industries and public investments to the city, São José dos Campos has begun to stand out in the economic and industrial scenario. Consequently, the city received a big migratory flow of workers, families and those who seeked a better life, which caused the horizontal e vertical expansion of the city. With the high demand of urban spaces and increasing of property speculation, the verticalization process was necessary. Along with the constructions of new buildings, the first models of the modern architecture began to emerge

Hematological analysis of Micropogonias Furnieri, Desmarest, 1823, Scianidae, from two estuaries of Baixada Santista, São paulo Brazil

Alterações hematológicas em peixes são consideradas uma importante ferramenta para avaliar processos patológicos decorrentes da exposição a poluentes ambientais. Micropogonias furnieri (Desmarest, 1823) (corvina) é comumente encontrada em regiões estuarinas e eventualmente está exposta a inúmeros contaminantes. No presente estudo foi avaliado o quadro hematológico de indivíduos de M. furnieri coletados na Baixada Santista: o Sistema Estuarino de Santos, considerado poluído, e o estuário do Rio Itanhaém (controle). Foram avaliados o número de Eritrócitos (Er), o Hematócrito (Ht), a taxa de Hemoglobina (Hb), o Volume Corpuscular Médio (VCM) e a Concentração de Hemoglobina Corpuscular Média (CHCM). Nos peixes coletados no Sistema Estuarino de Santos, os níveis de Ht foram significativamente menores, enquanto os níveis de CHCM e Hb foram significativamente mais altos, indicando que os prováveis efeitos estejam atribuídos aos diferentes níveis de contaminação encontrados nos estuários.
