Memória e Cidade, Fama e Infâmia: O Caso do Abrigo Municipal de Alienados Oscar Schneider / Memory and City, Fame and Infamy: The "Abrigo Municipal de Alienados Oscar Schneider" case / Memoria y ciudad, fama e infamia: El caso del "Abrigo Municipal de Alienados Oscar Schneider"

Este artigo apresenta resultados de uma pesquisa que investigou a produção de memórias e esquecimentos relacionada ao extinto "Abrigo Municipal de Alienados Oscar Schneider", instituição que funcionou em Joinville/SC entre 1923 e 1942 e teve seu prédio demolido cerca de 50 anos depois da sua construção. A inauguração da instituição marcou o início do projeto de "modernização-urbanização" de Joinville, pautado em normas higiênicas centradas nas novas prerrogativas da ciência moderna. Para a realização da pesquisa, rastreamos documentos que contam a história do Abrigo de Alienados: encontramos fotografias, um cartão-postal, trechos de documentos oficiais e notícias de jornal. Com esses documentos, problematizamos o campo de produção da fama e da infâmia em relação a determinados personagens que compuseram a cena dos acontecimentos dessa instituição. O olhar para os registros do Abrigo de Alienados procurou tensionar as diversas vozes que ali se encontram para seguir os rastros insignificantes de uma história, os quais correspondem a certos fatos e sujeitos que não foram considerados dignos de serem memorados: as vidas que sofreram a experiência do confinamento no Abrigo.

Composição de ácidos graxos de biossurfactantes produzidos por fungos filamentosos / Composition of fatty acids of biosurfactant produced by filamental fungi

Biossurfactantes são compostos com características tensoativas, produzidos por diversas espécies de microrganismos. Nesse estudo, a composição de ácidos graxos de biossurfactantes produzidos por fungos filamentosos endofíticos foram analisados. Para a produção dos biossurfactantes, empregou-se fontes de carbono (óleo vegetal de milho) e nitrogênio (ureia) de baixo custo no meio de cultivo. A composição de ácidos graxos foi determinada a partir da cromatografia gasosa. Foram identificados seis picos de ésteres metílicos de ácidos graxos, com predominância do ácido linoleico (C18:2n-6c) e ácido oleico (C18:1n-9c). Tanto os ácidos graxos saturados quanto os insaturados foram encontrados na estrutura dos biossurfactantes. Estes resultados demonstraram a importância destes compostos para potenciais aplicações em várias áreas industriais.

Ensayo de migración global en empaques para alimentos: evaluación de patrones internos alternativos / Overall migration test in food packaging: Evaluation of alternative internal standards / Ensaio de migração global em embalagens de alimentos: avaliação de padrões internos alternativos

Resumen En el ensayo de migración global para empaques plásticos destinados a alimentos grasos se emplea triheptadecanoato de glicerilo (GTM) como patrón interno para la cuantificación de los ésteres metílicos de ácidos grasos (FAMEs) por cromatografía de gases. En este trabajo se evaluaron 3-fenil propanoato de etilo (EFP) y ácido tetradecanóico (AM) como patrones internos alternativos. El uso de AM presentó comportamiento lineal (r > 0,99 y %Sb < 5%), buena precisión intermedia (HORRATr % 0,9) y exactitud (%R % 100,6%). En contraste, la evaluación del EFP, demostró que este no es un patrón interno adecuado para la cuantificación de FAMEs. De otra parte, se evaluó estadísticamente que no hay diferencias significativas en el cálculo de la migración global a partir de FAMEs cuantificados usando como patrón interno GTM o AM, mientras que el uso de EFP sí presenta diferencias significativas.

Abstract In the global migration test for plastic packaging intended for fatty foods, glyceryl triheptadecanoate (GTM) is used as the internal standard for the quantification of fatty acid methyl esters (FAMEs) by gas chromatography. In this work, ethyl 3-phenyl propanoate (EFP) and tetradecanoic acid (AM) were evaluated as alternative internal standards The use of AM presented linear behavior (r > 0.99 and %Sb < 5%), good intermediate precision (HORRATr % 0.9), and accuracy (%R % 100.6%). In contrast, the evaluation of EFP demonstrated that this is not an adequate internal standard for the quantification of FAMEs In addition, it was statistically evaluated that there are no significant differences in the calculation of the global migration from FAMEs quantified using either GTM or AM as internal standards, but the use of EFP presents significant differences.

Biomass production of multipopulation microalgae in open air pond for biofuel potential.

Biodiesel gains attention as it is made from renewable resources and has considerable environmental benefits. The present investigation has focused on large scale cultivation of multipopulation microalgae in open air pond using natural sea water without any additional nutritive supplements for low cost biomass production as a possible source of biofuel in large scale. Open air algal pond attained average chlorophyll concentration of 11.01 µg/L with the maximum of 43.65 µg/L as well as a higher lipid concentration of 18 % (w/w) with lipid content 9.3 mg/L on the 10th day of the culture; and maximum biomass of 0.36 g/L on the 7th day of the culture. Composition analysis of fatty acid methyl ester (FAME) was performed by gas chromatography and mass spectrometry (GCMS). Multipopulation of algal biomass had 18% of total lipid content with 55% of total saturated fatty acids (SFA), 35.3% of monounsaturated fatty acids (MUFA) and 9.7% of polyunsaturated fatty acids (PUFA), revealing a potential source of biofuel production at low cost.

A comparative study of coastal and clinical isolates of Pseudomonas aeruginosa

Pseudomonas aeruginosa is a ubiquitous Gram-negative bacterium having a versatile metabolic potential and great ecological and clinical significance. The geographical distribution of P. aeruginosahas revealed the existence of an unbiased genetic arrangement in terrestrial isolates. In contrast, there are very few reports about P. aeruginosa strains from marine environments. The present work was aimed at studying the distribution of P. aeruginosa in coastal waters along the Indian Peninsula and understanding the environmental influence on genotypic, metabolic and phenotypic characteristics by comparing marine and clinical isolates. Of the 785 marine isolates obtained on selective media, only 32 (~4.1%) were identified as P. aeruginosa, based on their fatty acid methyl ester profiles. A low Euclidian distance value (< 2.5) obtained from chemotaxonomic analysis suggested that all the environmental (coastal and marine) isolates originated from a single species. While UPGMA analyses of AP-PCR and phenotypic profiles separated the environmental and clinical isolates, fatty acid biotyping showed overlapping between most clinical and environmental isolates. Our study revealed the genetic diversity among different environmental isolates of P. aeruginosa. While biogeographical separation was not evident based solely on phenotypic and metabolic typing, genomic and metatranscriptomic studies are more likely to show differences between these isolates. Thus, newer and more insightful methods are required to understand the ecological distribution of this complex group of bacteria.

Statistical and evolutionary optimization for enhanced production of an anti-leukemic enzyme, L-asparaginase, in a protease-deficient Bacillus aryabhattai ITBHU02 isolated from the soil contaminated with hospital waste.

Over the past few decades, L-asparaginase has emerged as an excellent anti-neoplastic agent. In present study, a new strain ITBHU02, isolated from soil site near degrading hospital waste, was investigated for the production of extracellular L-asparaginase. Further, it was renamed as Bacillus aryabhattai ITBHU02 based on its phenotypical features, biochemical characteristics, fatty acid methyl ester (FAME) profile and phylogenetic similarity of 16S rDNA sequences. The strain was found protease-deficient and its optimal growth occurred at 37 °C and pH 7.5. The strain was capable of producing enzyme L-asparaginase with maximum specific activity of 3.02±0.3 Umg-1 protein, when grown in un-optimized medium composition and physical parameters. In order to improve the production of L-asparaginase by the isolate, response surface methodology (RSM) and genetic algorithm (GA) based techniques were implemented. The data achieved through the statistical design matrix were used for regression analysis and analysis of variance studies. Furthermore, GA was implemented utilizing polynomial regression equation as a fitness function. Maximum average L-asparaginase productivity of 6.35 Umg-1 was found at GA optimized concentrations of 4.07, 0.82, 4.91, and 5.2 gL‑1 for KH2PO4, MgSO4.7H2O, L-asparagine, and glucose respectively. The GA optimized yield of the enzyme was 7.8% higher in comparison to the yield obtained through RSM based optimization.

Biochemical and molecular characterization of Bacillus pumilus isolated from coastal environment in Cochin, India / Caracterização bioquímica e molecular de Bacillus pumilus isolado do ambiente costeiro de Cochin, Índia

Bacillus species constitute a diverse group of bacteria widely distributed in soil and the aquatic environment. In this study, Bacillus strains isolated from the coastal environment of Cochin, India were identified by detailed conventional biochemical methods, fatty acid methyl ester (FAME) analysis and partial 16S rDNA sequencing. Analysis of the data revealed that Bacillus pumilus was the most predominant species in the region under study followed by B. cereus and B. sphaericus. The B. pumilus isolates were further characterized by arbitrarily primed PCR (AP-PCR), antibiotic sensitivity profiling and PCR screening for known toxin genes associated with Bacillus spp. All B. pumilus isolates were biochemically identical, exhibited high protease and lipase activity and uniformly sensitive to antibiotics tested in this study. One strain of B. pumilus harboured cereulide synthetase gene cesB of B. cereus which was indistinguishable from rest of the isolates biochemically and by AP-PCR. This study reports, for the first time, the presence of the emetic toxin gene cesB in B. pumilus.

As espécies de Bacillus constituem um grupo diversificado de bactérias amplamente distribuídas no solo e no ambiente aquático. Neste estudo, cepas de Bacillus isoladas do ambiente costeiro de Cochin, Índia, foram identificadas através de métodos bioquímicos convencionais, análise de ésteres metílicos de ácidos graxos (FAME) e sequenciamento de 16S rDNA. A análise dos dados revelou que Bacillus pumilus foi a espécie predominante na região estudada, seguido de B. cereus e B. sphaericus. Os isolados de B. pumilus foram caracterizados através da reação em cadeia da polimerase com primers arbitrários (AP-PCR), perfil de sensibilidade a antibióticos e triagem por PCR de genes de toxinas associadas com Bacillus spp. Todos os isolados de B. pumilus foram bioquimicamente idênticos, apresentaram elevada atividade de protease e lipase e foram uniformemente sensíveis aos antibióticos estudados. Um dos isolados de B. pumilus apresentou o gene cesB de B. cereus, que não foinão distinguível dos demais isolados por testes bioquímicos nem por AP-PCR. Este é o primeiro relato da presença do gene cesB da toxina eméticaem B. pumilus.

Face Lift with SMAS and FAME(Finger Assisted Malar Fat Elevation) Technique

Although many methods have been developed to correct the aging process of the head and neck, the correction of nasolabial folds still remains a difficult area. The difficulty of correcting nasolabial fold is due to the anatomical location and the difference of aging process. From March 2000 to February 2001, the authors operated on 10 aging face patients using face lift with SMAS and FAME(Finger-assisted malar fat pad elevation) technique. The authors repositioned the SMAS-platysma flap posterosuperiorly and used finger dissection of the malar fat pad enabling a 3-dimensional correction and repositioning of the fat pad without detachment of the zygomatic ligament. The finger dissection of the malar fat pad attached to the skin enables a more anatomical correction of the malar fat pad with a more natural looking layer and longer lasting results in addition to decreased hematoma, edema and postoperative pain compared to previous methods.
