title: Decolorization of remazol brilliant blue R with laccase from Lentinus crinitus grown in agro-industrial by-products

description: ABSTRACT Lentinus crinitus is a white-rot fungus that produces laccase, an enzyme used for dye decolorization. Enzyme production depends on cultivation conditions, mainly agro-industrial by-products. We aimed to produce laccase from Lentinus crinitus with agro-industrial by-products for dye decolorization. Culture medium had coffee husk (CH) or citric pulp pellet (CP) and different nitrogen sources (urea, yeast extract, ammonium sulfate and sodium nitrate) at concentrations of 0, 0.7, 1.4, 2.8, 5.6 and 11.2 g/L. Enzymatic extract was used in the decolorization of remazol brilliant blue R. CH medium promoted greater laccase production than CP in all evaluated conditions. Urea provided the greatest laccase production for CH (37280 U/L) as well as for CP (34107 U/L). In CH medium, laccase activity was suppressed when carbon-to-nitrogen ratio changed from 4.5 to 1.56, but the other nitrogen concentrations did not affect laccase activity. For CP medium, reduction in carbon-to-nitrogen ratio from 6 to 1.76 increased laccase activity in 17%. The peak of laccase activity in CH medium occurred on the 11th day (41246 U/L) and in CP medium on the 12th day (32660 U/L). The maximum decolorization within 24 h was observed with CP enzymatic extract (74%) and with CH extract (76%).

title: Soft drink consumption and body mass index in Brazilian adolescents: National Adolescent Student Health Survey

description: ABSTRACT: Objective: To estimate the association between soft drink consumption and body mass index (BMI) in eutrophic and overweight adolescents. Methods: We used data from the National Adolescent Student Health Survey (Pesquisa Nacional de Saúde do Escolar - PeNSE) of 2009. The dependent variable (outcome) was the tertiles of BMI score (zBMI), and the main independent variable (exposure) was the consumption of sugar-sweetened soft drinks. The models included age, school type, home goods and services score, and maternal schooling as adjustment variables. We estimated the association between exposure and outcome by using multinomial regression models, stratified by gender, and eutrophic and overweight subgroups. Results: 23.8% of the adolescents evaluated were overweight, and 21.7% reported consuming soft drinks daily. For eutrophic boys, those who consumed soft drinks had a greater chance of being in higher zBMI tertiles than non-consumers. For overweight adolescents, both male and female, soft drink consumption was associated with a lower chance of being in the highest tertile of zBMI score. Conclusion: The results show the possibility of reverse causality between consumption of sweetened soft drinks and zBMI in the overweight adolescents group. For eutrophic male adolescents, soft drink consumption can potentially increase the chances of having higher zBMI, which reinforces the need for measures to significantly reduce the consumption of this beverage.

title: Psychometric Properties of the Brazilian Version of the Basic Needs Satisfaction in Sport Scale (BNSSS)

description: Abstract This study investigated the psychometric properties of the Brazilian version of the Basic Needs Satisfaction in Sport Scale (BNSSS). The instrument was translated and adapted by three experts. A total of 475 athletes participated in this study: 395 in a validity study and 80 in a temporal stability study. Factor analysis was used and reliability coefficients were estimated in the first study, while in the second study the intraclass correlation was calculated. The results showed clear and relevant translations between the three experts, and satisfactory internal consistency of items in Portuguese. Different models were tested (EFA and CFA), and the more stable model suggested the exclusion of eight items and the retention on three factors. Multigroup analysis showed partial invariance between the sexes. The scale showed temporal stability (ICC&gt; 0.70). It was concluded that the Brazilian version of BNSSS showed acceptable psychometric properties.

title: Impact of anxiety and depression on morbidity and mortality of patients with coronary syndrome

description: ABSTRACT Objective: Evaluate the impact of anxiety and depression on morbidity and mortality of patients with acute coronary syndrome. Method: Retrospective cohort study, with follow-up of two years, conducted with 94 patients. The morbidity and mortality (readmission, myocardial revascularization, and death) was evaluated immediately after discharge and after one and two years. Anxiety and depression were evaluated by the State-Trait Anxiety Inventory and by Beck’s Depression Inventory. The Kaplan-Meier estimator and the Logrank test were used. The significance level adopted was 0.05. Results: We observed that 76.6% of the patients did not present symptoms of depression or had mild signs, while 78.8% had low to moderate anxiety. The symptoms of depression and anxiety were not related to morbidity (need for MR p=0.098 and 0.56, respectively; readmission p=0.962 and 0.369, respectively) and mortality (p=0.434 and 0.077, respectively). Conclusion: No relationship was found between levels of anxiety and depression with the morbidity and mortality of patients.

title: Prevalence, Attitudes, and Factors Motivating Conscientious Objection toward Reproductive Health among Medical Students

description: Abstract Objective We have evaluated the prevalence of and the motivating factors behind the refusal to provide reproductive health services and the ethical knowledge of the subject among medical students from the Escola Bahiana de Medicina e Saúde Pública, in the state of Bahia, Brazil. Methods The present cross-sectional study involved 120 medical students. A questionnaire was utilized. The dependent variables were students’ objections (or not) regarding three clinical reproductive health cases: abortion provided by law, contraceptive guidance to an adolescent without parental consent, and prescription of emergency contraception. The independent variables were age, gender, religion, ethical value, degree of religiosity, and attendance at worship services. Ethical knowledge comprised an obligation to state the reasons for the objection, report possible alternatives, and referral to another professional. Data were analyzed with χ2 tests and t-tests with a significance level of 5%. Results Abortion, contraception to adolescents, and emergency contraception were refused by 35.8%, 17.5%, and 5.8% of the students, respectively. High religiosity (p &lt; 0.001) and higher attendance at worship services (p = 0.034) were predictors of refusing abortion. Refusal to provide contraception to adolescents was significantly higher among women than men (p = 0.037). Furthermore, 25% would not explain the reason for the refusal, 15% would not describe all the procedures used, and 25% would not refer the patient to another professional. Conclusion Abortion provided by law was the most objectionable situation. The motivating factors for this refusal were high commitment and religiosity. A reasonable portion of the students did not demonstrate ethical knowledge about the subject.

title: Robust volumetric models for supporting the management of secondary forest stands in the Southern Brazilian Atlantic Forest

description: Abstract The majority of Atlantic Forest fragments in Southern Brazil are second-growth forests dominated by fast-growing species with considerable market-value timber. Nevertheless, volume prediction models are scarce, especially to estimate tree total volume (i.e., stem plus branches). This study approached the issue through the following aims: to fit and select stem and total volume models (generic and species-specific) using data from 288 harvested trees in a management operation, and to fit generic and species-specific bark factors. The power model embedding diameter at breast height (D) and tree stem or total height (H) presented the greatest prediction strength for both stem and total tree volume. Models including only D to predict total tree volume were similar to double-entry models regarding goodness-of-fit. Therefore, they may be useful in the context of subtropical closed-canopy forests, where the difficulty and uncertainty in H measurements are not trivial. Species-specific models fitted for Miconia cinnamomifolia (DC) Naudin. and Hyeronima alchorneoides Allemão surpassed generic models only for the former species. Nevertheless, the prediction improvement should offset the eventual extra efforts implied in the collection of reliable samples of these species. Finally, bark factors stood as a satisfactory tool for inside bark mean volume estimation.

title: Negative Correlation between Placental Growth Factor and Endocan-1 in Women with Preeclampsia

description: Abstract Objective To analyze endocan-1, a biomarker of vascular endothelial related pathologies, and the placental growth factor (PlGF), an angiogenic factor and a placental dysfunction marker in patients with preeclampsia (PE). Methods Case-control study conducted at Hospital São Lucas, in the city of Porto Alegre, Brazil. Endocan-1 and PlGF levels were quantified in the maternal plasma using the MagPlexTH-C microsphere system (MAGPIX System, Luminex, Austin, Texas, US) and evaluated through analysis of covariance (ANCOVA) and adjusted by body mass index (BMI), gestational age and maternal age. To estimate the difference between the groups, the mean ratio (MR) and the 95% confidence interval (95%CI) were calculated. The Pearson correlation test was used to establish any association between endocan-1 and PlGF levels. The null hypothesis was rejected when p &lt; 0.05. Results The group of patients was composed by normotensive (n = 67) patients and patients with PE (n = 50). A negative correlation between endocan-1 and the PlGF was noted in the entire normotensive group (linear correlation coefficient [r] = -0.605; p &lt; 0.001), as well as in the PE group (r = -0.545; p &lt; 0.001). Conclusion Endocan-1 levels are increased in patients with PE, and are inversely correlated with PlGF levels. We suggest that it is important to analyze angiogenic and proinflammatory molecules concomitantly in women with PE to better understand the pathophysiology of the disease. Both molecules are strong candidates for PE biomarkers, and future studies will examine any mechanisms connecting these factors in PE.

title: Formação de professores de Química no Brasil e no mundo

description: ABSTRACT This text presents a panorama of Chemistry Education in several countries and focuses particularly on the training of Chemistry teachers in these different contexts. In this sense, the basic structure of the educational system of different countries is presented, as well as the particularities of the schools, such as working hours, number of students per class etc. The training of Chemistry teachers in each country is described in general terms and in terms of the curriculum, in addition to practical aspects of the profession, such as social valuation and the type of institution in which the training is done. The following countries were appraised: Australia, Brazil, Canada, Finland, Germany, India and United States. There are many differences between them, but some thingg in common in the best-performing countries in international assessments are close attention to, and monitoring of, the quality of teacher education, the social value of teachers and the working conditions in schools.

title: STOCHASTIC MODEL OF THE BRAZILIAN GPS NETWORK COORDINATES TIME SERIES

description: Abstract It is well known that daily estimates of GPS coordinates are highly temporally correlated and that the knowledge and understanding of this correlation allows to establish more realistic uncertainties of the parameters estimated from the data. Despite this, there are currently no studies related to the analysis and calculation of the noise sources in geodetic time series in Brazil. In this context, this paper focuses on the investigation of the stochastic properties of a total of 486 coordinates time series from 159 GPS stations belonging to the Brazilian Network for Continuous Monitoring of GNSS (RBMC) using the maximum likelihood estimation approach. To reliably describe the GPS time series, we evaluate 4 possible stochastic models as models of each time series: 3 models with integer spectral indices (white noise, flicker plus white noise and random-walk plus white noise model) and 1 with fractional spectral index (fractional power-law plus white noise). By comparing the calculated noise content values for each model, it is possible to demonstrate a stepwise increase of the noise content, being the combination of a fractional power-law process and white noise process, the model with smaller values and the combination of random walk process with white noise process, the model with greater values. The analysis of the spatial distribution of the noise values of the processes allow demonstrate that the GPS sites with the highest accumulated noise values, coincide with sites located in coastal zones and river basins and that their stochastic properties can be aliased by the occurrence of different physical signals typical of this type of zones, as the case of the hydrological loading effect.
