Resumo: Background: Biodegradation is a reliable approach for efficiently eliminating persistent pollutants such as chlorpyrifos. Despite many bacteria or fungi isolated from contaminated environment and capable of degrading chlorpyrifos, limited enzymes responsible for its degradation have been identified, let alone the catalytic mechanism of the enzymes. Results: In present study, the gene cpd encoding a chlorpyrifos hydrolase was cloned by analysis of genomic sequence of Paracoccus sp. TRP. Phylogenetic analysis and BLAST indicated that CPD was a novel member of organophosphate hydrolases. The purified CPD enzyme, with conserved catalytic triad (Ser155-Asp251-His281) and motif Gly-Asp-Ser-Ala-Gly, was significantly inhibited by PMSF, a serine modifier. Molecular docking between CPD and chlorpyrifos showed that Ser155 was adjacent to chlorpyrifos, which indicated that Ser155 may be the active amino acid involved in chlorpyrifos degradation. This speculation was confirmed by site-directed mutagenesis of Ser155Ala accounting for the decreased activity of CPD towards chlorpyrifos. According to the key role of Ser155 in chlorpyrifos degradation and molecular docking conformation, the nucleophilic catalytic mechanism for chlorpyrifos degradation by CPD was proposed. Conclusion: The novel enzyme CPD was capable of hydrolyze chlorpyrifos and Ser155 played key role during degradation of chlorpyrifos.

Resumo: Background: Inferior Tieguanyin oolong tea leaves were treated with tannase. The content and bioactivity of catechins in extracts from the treated tea leaves were investigated to assess the improvement in the quality of inferior Tieguanyin oolong tea. Results: Analysis showed that after treatment, the esterified catechin content decreased by 23.5%, whereas non-galloylated catechin and gallic acid contents increased by 15.3% and 182%, respectively. The extracts from tannase-treated tea leaves showed reduced ability to bind to BSA and decreased tea cream levels. The extracts also exhibited increased antioxidant ability to scavenge OH and DPPH radicals, increased ferric reducing power, and decreased inhibitory effects on pancreatic α-amylase and lipase activities. Conclusions: These results suggested that tannase treatment could improve the quality of inferior Tieguanyin oolong tea leaves.

Resumo: Background: Laccases are copper-containing enzymes which have been used as green biocatalysts for many industrial processes. Although bacterial laccases have high stabilities which facilitate their application under harsh conditions, their activities and production yields are usually very low. In this work, we attempt to use a combinatorial strategy, including site-directed mutagenesis, codon and cultivation optimization, for improving the productivity of a thermo-alkali stable bacterial laccase in Pichia pastoris. Results: A D500G mutant of Bacillus licheniformis LS04 laccase, which was constructed by site-directed mutagenesis, demonstrated 2.1-fold higher activity when expressed in P. pastoris. The D500G variant retained similar catalytic characteristics to the wild-type laccase, and could efficiently decolorize synthetic dyes at alkaline conditions. Various cultivation factors such as medium components, pH and temperature were investigated for their effects on laccase expression. After cultivation optimization, a laccase activity of 347 ± 7 U/L was finally achieved for D500G after 3 d of induction, which was about 9.3 times higher than that of wild-type enzyme. The protein yield under the optimized conditions was about 59 mg/L for D500G. Conclusions: The productivity of the thermo-alkali stable laccase from B. licheniformis expressed in P. pastoris was significantly improved through the combination of site-directed mutagenesis and optimization of the cultivation process. The mutant enzyme retains good stability under high temperature and alkaline conditions, and is a good candidate for industrial application in dye decolorization.

Resumo: Background: A simple and efficient strategy for agarase immobilization was developed with carboxyl-functionalized magnetic nanoparticles (CMNPs) as support. The CMNPs and immobilized agarase (agarase-CMNPs) were characterized by transmission electron microscopy, dynamic light scattering, vibrating sample magnetometry, scanning electron microscopy, X-ray diffraction, thermogravimetric analysis, and zeta-potential analysis. The hydrolyzed products were separated and detected by ESI-TOF-MS. Results: The agarase-CMNPs exhibited a regular spherical shape with a mean diameter of 12 nm, whereas their average size in the aqueous solution was 43.7 nm as measured by dynamic light scattering. These results indicated that agarase-CMNPs had water swelling properties. Saturation magnetizations were 44 and 29 emu/g for the carriers and agarase-CMNPs, respectively. Thus, the particles had superparamagnetic characteristics, and agarase was successfully immobilized onto the supports. Agaro-oligosaccharides were prepared with agar as substrate using agarase-CMNPs as biocatalyst. The catalytic activity of agarase-CMNPs was unchanged after six reuses. The ESI-TOF mass spectrogram showed that the major products hydrolyzed by agarase-CMNPs after six recycle uses were neoagarotetraose, neoagarohexaose, and neoagarooctaose. Meanwhile, the end-products after 90 min of enzymatic treatment by agarase-CMNPs were neoagarobiose and neoagarotetraose. Conclusions: The enhanced agarase properties upon immobilization suggested that CMNPs can be effective carriers for agarase immobilization. Agarase-CMNPs can be remarkably used in developing systems for repeated batch production of agar-derived oligosaccharides.

Resumo: O presente trabalho descreve o uso de carboidratos como materiais de partida para a preparação de catalisadores quirais e também de substratos quirais. Primeiramente estudos envolvendo a aplicação de amino álcoois derivados de carboidratos na arilação assimétrica de aldeídos, usando ácidos arilborônicos como fontes de grupos arila transferíveis, revelaram que um ligante preparado a partir da D-xilose mostrou-se bastante eficiente e conduziu aos produtos em excelentes rendimentos e altos excessos enantioméricos. Posteriormente a arilação de aldeídos derivados de carboidratos é descrita. Em alguns casos diastereosseletividades maiores que 20:1 foram observadas e a metodologia foi aplicada a síntese total da 7-epi-goniofufurona e análogos

The work described herein is centered on the use of carbohydrates as starting materials for the synthesis of chiral ligands and chiral sugar-derivatives. Initially, chiral amino alcohols were studied as ligands for the asymmetric arylation of aldehydes using aryl boronic acids as the source of transferable aryl groups. We found that a chiral ligand derived from D-xylose was very efficient and the desired products were obtained in excellent yields and enantiomeric excesses. In addition, the arylation of sugar-based aldehydes was also studied. In many cases, excellent diastereoselectivities of >20:1 were achieved and the methodology was employed in the total synthesis of 7-epi-goniofufurone and analogues

Idioma: en.
Resumo: RESUMO: Objetivo: Analisar as diferenças regionais e os fatores associados à prática de atividade física no lazer em adultos participantes da Pesquisa Nacional de Saúde, de 2013. Métodos: Este estudo foi realizado com os dados da Pesquisa Nacional de Saúde, realizada em 2013 com uma amostra aproximada de 63.000 adultos (18+ anos). Para cada uma das cinco regiões do Brasil foi calculada a prevalência de adultos ativos no lazer, sendo classificados como ativos aqueles participantes que praticaram pelo menos 150 minutos por semana de atividades físicas no lazer. Resultados: A prevalência de ativos no lazer variou de 21,9% no Sul a 24,4% no Centro-Oeste. Homens foram 1,48 (IC95% 1,40 - 1,57) vezes mais ativos que as mulheres, sendo a região Norte aquela que apresentou maior diferença entre sexos. A prevalência de ativos foi 67% menor entre aqueles com 75+ anos quando comparado ao grupo de 18-24 anos, sendo que esta diferença foi mais acentuada na região Norte. Aqueles com maior grau de instrução foram, em média, três vezes mais ativos que os participantes com menor grau de instrução. Em termos de grau de instrução, a menor diferença observada ocorreu no Nordeste. Conclusões: Apesar das pequenas variações na prevalência de prática de atividade física no lazer entre as regiões, quando são considerados subgrupos populacionais, diferenças importantes são observadas. Estes resultados sugerem a necessidade de ações de promoção de atividade física com diferentes abordagens em cada uma das cinco regiões do Brasil.

ABSTRACT: Objective: To analyze the regional differences and factors associated with physical activity during the leisure time in the adult participants of the National Health Survey, 2013. Methods: This study was carried out with the data from the National Health Survey, conducted in 2013 with an approximate sample of 63,000 adults (18+ years). For each of the five regions of Brazil, the prevalence of physically active adults during the leisure time was calculated, and the participants were classified as active if they practiced at least 150 minutes per week of physical activity during leisure time. Results: The prevalence of individuals who were active during the leisure time varied from 21.9% in the south to 24.4% in the midwest. The men were 1.48 (95%CI 1.40-1.57) times more active than women, with the northern region showing the highest difference between the sexes. The prevalence of active individuals was 67% lower among those aged 75+ years when compared with the 18-24 age group, and this difference was more marked in the north. Those with higher levels of education were on average three times more active than the participants with lower education levels. In terms of education level, the lowest difference was observed in the northeast. Conclusion: Despite the slight variations in the prevalence of physical activity during the leisure time among the regions, when population subgroups are considered, important differences were observed. These results suggest the need for promotion initiatives on physical activity with different approaches in each of the five regions of Brazil.

Título: Exposure of periodontal ligament progenitor cells to lipopolysaccharide from Escherichia coli changes osteoblast differentiation pattern
Fonte: J. appl. oral sci;23(2):145-152, Mar-Apr/2015. graf.
Idioma: en.
Resumo: Periodontal ligament mesenchymal stem cells (PDLMSCs) are an important alternative source of adult stem cells and may be applied for periodontal tissue regeneration, neuroregenerative medicine, and heart valve tissue engineering. However, little is known about the impact of bacterial toxins on the biological properties of PDLSMSCs, including self-renewal, differentiation, and synthesis of extracellular matrix. Objective : This study investigated whether proliferation, expression of pro-inflammatory cytokines, and osteogenic differentiation of CD105-enriched PDL progenitor cell populations (PDL-CD105+ cells) would be affected by exposure to bacterial lipopolysaccharide from Escherichia coli (EcLPS). Material and Methods : Toll-like receptor 4 (TLR4) expression was assessed in PDL-CD105+ cells by the immunostaining technique and confirmed using Western blotting assay. Afterwards, these cells were exposed to EcLPS, and the following assays were carried out: (i) cell viability using MTS; (ii) expression of the interleukin-1 beta (IL-1β), interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor alpha (TNF-α) genes; (iii) osteoblast differentiation assessed by mineralization in vitro, and by mRNA levels of run-related transcription factor-2 (RUNX2), alkaline phosphatase (ALP) and osteocalcin (OCN) determined by quantitative PCR. Results : PDL-CD105+ cells were identified as positive for TLR4. EcLPS did not affect cell viability, but induced a significant increase of transcripts for IL-6 and IL-8. Under osteogenic condition, PDL-CD105+ cells exposed to EcLPS presented an increase of mineralized matrix deposition and higher RUNX2 and ALP mRNA levels when compared to the control group. Conclusions : These results provide evidence that CD105-enriched PDL progenitor cells are able to adapt to continuous Escherichia coli endotoxin challenge, leading to an upregulation of osteogenic activities. .

Título: Sinovite e tenossinovite no Brasil: uma análise dos benefícios auxílio-doença / Synovitis and tenosynovitis in Brazil: analysis of sickness benefit claims
Fonte: Rev. bras. epidemiol;18(1):194-207, Jan-Mar/2015. tab.
Idioma: pt.
Resumo: OBJETIVO: Analisar os fatores pessoais associados à prevalência e duração dos benefícios auxílio-doença decorrentes de sinovite e tenossinovite (CID10 M65). MÉTODO: Estudo transversal referente aos benefícios auxílio-doença decorrentes de sinovite e tenossinovite concedidos pelo Instituto Nacional de Seguro Social aos empregados no Brasil em 2008. Dados sobre o ramo de atividade econômica (Classificação Nacional de Atividades Econômicas - CNAE divisão, classe), sexo, idade, espécie e duração dos benefícios foram coletados do Sistema Único de Benefícios. A população corresponde à média mensal dos vínculos empregatícios declarados ao Cadastro Nacional de Informações Sociais. RESULTADOS: Em 2008 foram concedidos 35.601 benefícios auxílio-doença decorrentes de sinovite e tenossinovite, com prevalência de 10,9/10.000 vínculos empregatícios. No conjunto dos benefícios auxílio-doença houve maior razão de prevalência (RP) acidentária (RP 1,2), sendo esta maior em mulheres (RP 3,3), e em trabalhadores com idade acima de 39 anos (RP 1,4). As CNAE 37-Esgoto (55,4) e 60-Atividade de rádio e TV (47,1) apresentaram as maiores prevalências, no entanto, 64-Atividade de serviços financeiros e 6422-Bancos múltiplos caracterizaram mais acidentes de trabalho (RP 3,2 e 3,8, respectivamente) e maior duração (70 e 73 dias, respectivamente). A maior duração de benefício ocorreu entre trabalhadores com idade superior a 39 anos. Tanto a CNAE-divisão 60-Atividade de rádio e TV, quanto a CNAE-classe 6010-Atividade de rádio apresentaram elevadas razões de feminilidade (RP 8,1 e 10,8, respectivamente). CONCLUSÃO: A incapacidade para o trabalho por sinovite e tenossinovite apresenta associação tanto da prevalência quanto da duração com o ramo de atividade, sexo, idade e espécie de benefício (previdenciário/acidentário). .

OBJECTIVE: To analyse the personal and occupational factors associated with the prevalence and duration of sickness benefit claims due to synovitis and tenosynovitis (CID10 M65). METHODS: Cross-sectional study regarding sickness benefit claims due to synovitis and tenosynovitis granted to employees by National Institute of Social Security in Brazil in 2008. Data on economic activity (Economic Activities National Classification - CNAE division, class), sex, age, type and duration of benefits were collected from the Unified Benefit System. The study's population consists of the average monthly employment contracts declared to the National Register of Social Information. RESULTS: In 2008, 35,601 employees were granted sickness benefits due to synovitis and tenosynovitis, with a prevalence of 10.9/10,000 employments. Sickness benefits showed higher prevalence rates (PR) for work-related claims (PR 1,2), mostly made by females (PR 3.3) and by workers older than 39 years (PR 1,4). The CNAE 37-Sewage (55.4) and 60-Broadcasting Activity (47.1) had the highest overall prevalence. However, the 64-Financial service activities, except insurance and pension funding and 6422-Multiple banks with commercial service had the highest rates of work-related claims (RP 3.2 and 3.8, respectively), and the longer duration (70 and 73 days, respectively). Workers older than 39 years had the highest durations of work disability claims. Both the CNAE-division 60-Broadcasting Activity, and the CNAE-class 6010-Radio showed a high activity ratio of females (PR 8.1 and 10.8, respectively). CONCLUSION: The work disability due to synovitis and tenosynovitis presents prevalence and duration associated with economic activity, sex, age and kind of benefit (non work-related and work-related claims). .

Resumo: En el marco de la creciente feminización de la profesión médica en México, el artículo indaga sobre las características de este proceso para el caso de la ginecobstetricia. Considerando la feminización como un proceso de cambio, que se analiza cuantitativa y cualitativamente, el artículo se detiene en especial en las experiencias de las mujeres ginecobstetras, experiencias que se dan en el seno de una especialidad que, desde sus orígenes, funcionó como un dispositivo de control del cuerpo de las mujeres. Basado en una investigación etnográfica, el artículo combina fuentes estadísticas, de archivo y de observación de campo. El material que surge de las entrevistas muestra las experiencias y tensiones que viven las ginecobstetras en este contexto.

In the framework of an increasing feminization of the medical profession in Mexico, this article explores the characteristics of this process in the obstetrics and gynecology specialty. Understanding feminization as a process of change to be analyzed both quantitatively and qualitatively, the article focuses special attention on the experiences of female obstetrician-gynecologists within a medical specialty that has since its origins functioned as a mechanism of control over women's bodies. Based on ethnographic research, the article combines statistical and archival sources and field observation. The interviews reveal the experiences and tensions women obstetrician-gynecologists encounter in this context.

Título: Static body postural misalignment in individuals with temporomandibular disorders: a systematic review
Fonte: Braz. j. phys. ther. (Impr.) = Rev. bras. fisioter;18(6):481-501, 09/01/2015. tab, graf.
Idioma: en.
Resumo: BACKGROUND: The association between body postural changes and temporomandibular disorders (TMD) has been widely discussed in the literature, however, there is little evidence to support this association. OBJECTIVES: The aim of the present study was to conduct a systematic review to assess the evidence concerning the association between static body postural misalignment and TMD. METHOD: A search was conducted in the PubMed/Medline, Embase, Lilacs, Scielo, Cochrane, and Scopus databases including studies published in English between 1950 and March 2012. Cross-sectional, cohort, case control, and survey studies that assessed body posture in TMD patients were selected. Two reviewers performed each step independently. A methodological checklist was used to evaluate the quality of the selected articles. RESULTS: Twenty studies were analyzed for their methodological quality. Only one study was classified as a moderate quality study and two were classified as strong quality studies. Among all studies considered, only 12 included craniocervical postural assessment, 2 included assessment of craniocervical and shoulder postures,, and 6 included global assessment of body posture. CONCLUSION: There is strong evidence of craniocervical postural changes in myogenous TMD, moderate evidence of cervical postural misalignment in arthrogenous TMD, and no evidence of absence of craniocervical postural misalignment in mixed TMD patients or of global body postural misalignment in patients with TMD. It is important to note the poor methodological quality of the studies, particularly those regarding global body postural misalignment in TMD patients. .
