A Brazilian marginal literature in the current French context: an interview with Paula Anacaona
Qual seria o lugar da literatura marginal brasileira no atual cenário internacional ? A voz oriunda das periferias seria uma nova forma de expressão literária em desenvolvimento, ou apenas a repetição de um clichê historicamente atribuído à sociedade brasileira ? Numa conversa franca, Paula Anacaona nos revela seu ponto de vista sobre o assunto, compartilhando sua experiência profissional no meio editorial francês.
Fundadora das edições Anacaona, seu projeto foi motivado por um desejo pessoal de difundir a produção literária das minorias e suas diversidades. Suas publicações privilegiam as narrativas consideradas marginais, sendo, em sua maioria, oriundas das periferias urbanas ou dos distantes espaços rurais brasileiros. Mas ao trazer à tona esses espaços « esquecidos » e essas vozes silenciadas, estaríamos nós contribuindo para a disseminação de um singular movimento literário, ou estaríamos uma vez mais caindo na armadilha do esperado « exotismo » brasileiro? Eis algumas questões que, através dessa entrevista, buscamos refletir.What would be the place of Brazilian marginal literature in the current international scene ? The voice that coming from suburbs would be a developing form of literary expression, or just a repetition of a cliché historically attributed to Brazilian society?
In an frank conversation, Paula Anacaona explain her point of view on this matter, sharing her professional experience in the French editorial environment.
Founder the Anacaona's editions, her project was motivated of a personal desire to spread the literary production of minorities and their diversities.
Her publications focus on narratives considered marginal.
Indeed, such publications predominantly come from the urban suburbs or deeply rural areas of Brazil.
However, in revealing these “forgotten” spaces and these silenced voices, could we be contributing to the spread of a singular literary movement, or could we once again be falling into the trap of the expected Brazilian "exoticism"?
These are some points that we consider to reflect through this interview
Associação entre adiposidade, parâmetros metabólicos e marcadores inflamatórios em adolescentes do sexo feminino
Orientadora: Profª. Drª Rosana Bento RadominskiDissertação (mestrado)- Universidade Federal do Paraná, Setor de Ciências da Saúde, Programa de Pós-Graduação em Segurança Alimentar e Nutricional. Defesa: Curitiba, 25/11/2014Inclui referênciasResumo: A obesidade aumentou de forma expressiva nas ultimas decadas, especialmente na populacao pediatrica. Estudos que avaliaram a distribuicao de gordura corporal em adultos demonstraram que a adiposidade central se correlaciona com alteracoes metabolicas e com processo inflamatorio subclinico que podem resultar em resistencia a insulina, hipertensao arterial e dislipidemia; fatores estes implicados no aumento do risco de doencas cardiovasculares e diabetes. O objetivo do presente estudo foi verificar a associacao entre indicadores de adiposidade central e total com parametros metabolicos e inflamatorios em adolescentes do sexo feminino. A amostra foi composta por 53 meninas de 13 a 17 anos de uma escola publica na cidade de Curitiba. Os indicadores de adiposidade estudados foram indice de massa corporal (IMC), circunferencia de cintura (CC), massa gorda (MG), gordura troncular (GT) e percentual de gordura. A composicao corporal foi obtida por absorciometria por dupla emissao de raios-x (DXA). Os parametros metabolicos e inflamatorios analisados foram pressao arterial sistolica (PAS) e diastolica (PAD), glicemia, insulina, HOMA1-IR, perfil lipidico, proteina C reativa (PCR), interleucina 6 (IL-6), fator de necrose tumoral-ƒ¿ (TNF-ƒ¿), leptina, adiponectina e resistina. Utilizaram-se a correlacao de Pearson e a regressao linear bivariada e multipla, considerando-se p .0,05. Houve correlacao positiva significativa entre todos os indicadores de adiposidade com PAS, PAD, insulina, HOMA1-IR, PCR e leptina. Os triglicerideos se correlacionaram positivamente apenas com IMC e CC e a adiponectina apresentou correlacao negativa com o IMC. TNF-ƒ¿ e IL-6 nao se associaram as variaveis estudadas, assim como a glicemia, colesterol total, colesterol HDL e LDL. O IMC apresentou associacao positiva significativa com a maioria dos parametros estudados nesta populacao, comparavel aquelas obtidas com a medida da CC e a medida direta da adiposidade pela DXA, e ate o momento parece ser suficiente para detectar, nesta faixa etaria, individuos em risco de complicacoes da obesidade. Palavras-chave: Adolescentes, Obesidade, Gordura abdominal, Risco cardiovascularAbstract: Obesity has increased significantly in recent decades, especially in the pediatric population. Studies evaluating the distribution of body fat in adults have shown that abdominal adiposity is strongly correlated with metabolic changes and subclinical inflammation that may result in insulin resistance, hypertension and dyslipidemia; these factors are implicated in increased risk of cardiovascular disease and diabetes. The aim of this study was to investigate the association between total and central adiposity in female adolescents. The sample consisted of 53 adolescents aged 13 to 17 years of a public school in the city of Curitiba. The indicators of adiposity studied were body mass index (BMI), waist circumference (WC), trunk fat mass, total fat mass and fat percentage measured by dual-energy X-ray absorptiometry (DXA). The metabolic and inflammatory parameters studied were systolic blood pressure (SBP), diastolic blood pressure (DBP), glucose, insulin, HOMA1-IR, lipids, reactive c protein (RCP), interleukin-6 (IL-6), TNF-ƒ¿, leptin, adiponectin and resistin. PearsonLs correlation and multiple bivariate linear regression were used considering p value .0,05. There was a significant positive, correlation between all indicators of adiposity with SBP, DBP, insulin, HOMA1-IR, RCP and leptin. Triglycerides were positively correlated with BMI and WC, and adiponectin correlated negatively with BMI. TNF-ƒ¿, IL-6, glucose, total cholesterol, HDL and LDL cholesterol did not correlate to the studied variables. BMI showed a significant association with most of the parameters studied in this population, comparable to those obtained with the measurement of WC and the direct measure of adiposity by DXA, and so far, seems to be sufficient to detect in this age group, individuals with risk of obesity complications.

OS IMPACTOS DA ADOÇÃO DE PROGNÓSTICOS DE RISCOS NO POLICIAMENTO SOB A SELETIVIDADE PENAL E AS DESIGUALDADES SOCIAIS
No cenário atual, em que mecanismos matemáticos e estatísticos se destacam na resolução das adversidades sociais – em virtude da suposta precisão e certeza conferida pelos mesmos –, os prognósticos de riscos, edificados por lógica algorítmica, ganham proeminência destinando-se à prática do policiamento preditivo. O presente estudo, explicativo-descritivo, empregou as modalidades bibliográfica e documental, e objetiva analisar como a adoção de prognósticos de riscos no policiamento impacta a seletividade penal e as desigualdades sociais. A pesquisa provoca inquietações que incentivam novos estudos, apresenta questionamentos sobre a suposta eficiência de prognósticos de riscos e orienta possíveis caminhos para a atuação policial

Ionic liquids as entrainers for terpenes fractionation and other relevant separation problems
This work discusses the potential of two phosphonium-based ionic liquids (ILs), [P6,6,6,14]Cl and [P6,6,6,14][(C8H17)2PO2], and one methylimidazolium-based IL, [C4mim][OAc], as entrainers in the fractionation of terpene mixtures, in the desulfurization and denitrification of fuel oils, and in the separation of aromatics from aliphatic hydrocarbons. To this aim, the activity coefficients at infinite dilution of 45 solutes were obtained by gas-chromatography in the temperature range (333.15–458.15) K. Selectivities and capacities were calculated showing that [P6,6,6,14]Cl is adequate for the fractionation of (−)-menthone/L-(−)-menthol mixture, being also a suitable option for the deterpenation of citrus essential oil, and the removal of thiophene and pyridine from aliphatic hydrocarbons. To complement the experimental measurements COSMO-RS model was tested, demonstrating good potential to screen separation agents and give insights for several important separation problems, including the removal of contaminants from fuels and the isolation, fractionation and purification of terpenes mixtures.This work was developed within the scope of the project CICECOAveiro

Comparison of two computational methods for solvent screening in countercurrent and centrifugal partition chromatography
Countercurrent and centrifugal partition chromatography are techniques applied in the separation and isolation of compounds from natural extracts. One of the key design parameters of these processes is the selection of the biphasic solvent system that provides for the adequate partitioning of the solutes. To address this challenging task, the fully predictive Conductor-like Screening Model for Real Solvents (COSMO-RS) and the semi-predictive Non-Random Two-Liquid Segment Activity Coefficient (NRTL-SAC) model were applied to estimate the partition coefficients ( K ) of four model phenolic compounds (vanillin, ferulic acid, ( S )-hesperetin and quercetin) in different solvent systems. Complementing the experimental data collected in the literature, partition coefficients of each solute in binary, or quaternary, solvent sys- tems were measured at 298.2 K. Higher deviations from the experimental data were obtained using the predictive COSMO-RS model, with an average RMSD (root-mean-square deviation) in log( K ) of 1.17 of all four solutes (61 data points), providing a satisfactory quantitative description only for the systems containing vanillin (RSMD = 0.57). For the NRTL-SAC model, the molecular parameters of the solutes were initially calculated by correlating a set of K and solubility ( x , in mole fraction) data (16 partition coefficients and 44 solubility data points), for which average RMSD values of 0.07 and 0.41 were obtained in log( K ) and log( x ) , respectively. The predictions of the remaining log( K ) data (45 partition coefficients) resulted in an average RMSD of 0.43, suggesting that the NRTL-SAC model was a more reliable quantitative solvent screening tool. Depending on the amount of available solubility and partition data, both models can be valuable alternatives in the preliminary stages of solvent screening destined to select the optimal mobile and stationary phases for a given separation.This work was developed within the scope of the project All- Nat - POCI-01–0145-FEDER-030463 (PTDC/EQU-EPQ/30463/2017), funded by FEDER funds through COMPETE2020 –Prog.

Conclusão:Investimentos na capacitação do enfermeiro são fundamentais para um atendimento integral voltado à alimentação
Apical Negative Pressure irrigation presents tissue compatibility in immature teeth
Aim: To compare the apical negative pressure irrigation (ANP) with conventional irrigation in the teeth of immature dogs with apical periodontitis. Methods: Fifty-two immature pre-molar root canals were randomly assigned into 4 groups: ANP (n=15); conventional irrigation (n=17); healthy teeth (control) (n = 10); and teeth with untreated apical periodontitis (control) (n=10). After induction of apical periodontitis, teeth were instrumented using EndoVac® (apical negative pressure irrigation) or conventional irrigation. The animals were euthanized after 90 days. The sections were stained by HE and analyzed under conventional and fluorescence microscopy. TRAP histoenzymology was also performed. Statistical analyses were performed with the significance level set at 5%. Results: There was difference in the histopathological parameters between ANP and conventional groups (p;0.05). However, a lower number of osteoclasts was observed in the ANP group (
Bacterial endotoxin adhesion to different types of orthodontic adhesives
Bacterial endotoxin (LPS) adhesion to orthodontic brackets is a known contributing factor to inflammation of the adjacent gingival tissues. Objective The aim of this study was to assess whether LPS adheres to orthodontic adhesive systems, comparing two commercial brands. Material and Methods Forty specimens were fabricated from Transbond XT and Light Bond composite and bonding agent components (n=10/component), then contaminated by immersion in a bacterial endotoxin solution. Contaminated and non-contaminated acrylic resin samples were used as positive and negative control groups, respectively. LPS quantification was performed by the Limulus Amebocyte Lysate QCL-1000™ test. Data obtained were scored and subjected to the Chi-square test using a significance level of 5%. Results There was endotoxin adhesion to all materials (p;0.05). There was no significant difference (p>;0.05) among commercial brands. Affinity of endotoxin was significantly greater for the bonding agents (p=0.0025). Conclusions LPS adhered to both orthodontic adhesive systems. Regardless of the brand, the endotoxin had higher affinity for the bonding agents than for the composites. There is no previous study assessing the affinity of LPS for orthodontic adhesive systems. This study revealed that LPS adheres to orthodontic adhesive systems. Therefore, additional care is recommended to orthodontic applications of these materials
