title: Incidence of hydrocolloid type on quality parameters in mango leathers (Mangifera indica L.) Yulima variety

description: Abstract The effect of four hydrocolloids on the physico-chemical, bioactive and rheological properties in sweetened mango leather sheets of the Yulima variety were analyzed. Parametric and non-parametric statistical tests were done to analyze the differences among samples (four of treatment against two of control). The findings show significant positive effects caused by the hydrocolloids made from Gum Arabic (AG), Maltodextrin (MTD) and Citric Slow Pectin (CSP) on leathers’ quality and appearance attributes. Only the Carboxymethylcellulose (CMC) reported adverse effects on the mango leather's quality; therefore, its use on an industrial scale is not recommended for this line of processed product.

title: Primary and secondary modeling of Brochothrix thermosphacta growth under different temperature and ph values

description: Abstract Bochothrix thermosphacta is an optional aerobic psychrotrophic related to the meat deterioration and consequently loss of a refrigerated cargo contaminated. Predictive microbiology can be used as a quality assurance tool, since it allows the prediction of microbial response based in pass observations. This work aimed model the growth of B. thermosphacta under variation of pH and temperature. For this purpose, the experimental growth data were fitted to the primary models of Baranyi and Roberts and the modified Gompertz model and the data for the maximum rate of growth (μmax) were adjusted to Ratkowsky extended secondary model. The results showed us that the influence of temperature on growth parameters was more evident than pH. Since, by fixing the temperature the change of pH little altered the μmax. However, as the temperature rises the elevation at the μmax is considerable, for example the comparison of predicted values for μmax, when the temperature exceeds 4 °C to 12 °C, it is clear that these rates are more than double. Finally, it is emphasized that all tested models feature good fit to the experimental data, which makes them validated for prediction growth of B. thermosphacta in the same conditions tested experimentally.

title: Use of vasopressin in the treatment of refractory septic shock

description: ABSTRACT Objective: To evaluate the short-term evolution of patients with septic shock refractory to norepinephrine treated with vasopressin in an intensive care unit of a university hospital. Methods: An unmatched retrospective study (case series) was performed. Clinical, laboratory, and anthropometric data were collected from patients who received vasopressin infusion for treatment of catecholamine-refractory shock from December 2014 to June 2016. For the assessment of severity, APACHE II and SOFA scores were used. The main outcome was mortality at 3 and 30 days. Results: A total of 80 patients were included, of which 60% were male. In 86.3% of the cases, APACHE II was observed in the highest ranges (&gt; 20). The 30-day mortality was 86.2%, and 75% of the patients died within 72 hours after starting vasopressin. Conclusion: The series evaluated had high mortality in the first 72 hours of treatment with vasopressin. The use of vasopressin in patients who are refractory to norepinephrine had little or no impact on mortality. It was not possible to exclude the possibility that the high mortality in the present study was linked to the relatively late onset (after established refractoriness of norepinephrine) of vasopressin; this hypothesis should be further evaluated in a randomized study.

title: Effects of enzymatic hydrolysis (Flavourzyme®) assisted by ultrasound in the structural and functional properties of hydrolyzates from different bovine collagens

description: Abstract This study aimed at evaluating the functional (antioxidant and antimicrobial activity) and structural properties of different bovine collagen hydrolysates obtained through ultrasound assisted enzymatic hydrolysis (Flavourzyme®). The use of previous or simultaneous ultrasound strengthened the enzymatic hydrolysis of bovine collagen samples, generating higher number of bands in wave number (cm-1). The best treatment was the enzymatic hydrolysis, while for the powder fiber and hydrolysate, it was the ultrasound hydrolysis. The sample that showed the highest inhibiting action to the gram-negative bacteria Salmonella choleraesuis growth and gram-positive bacteria Staphylococcus aureus hydrolyzed with enzyme and simultaneous ultrasound. Therefore, the enzymatic hydrolysis (Flavourzyme®) was concluded to enable the hydrolysis of samples, providing structural rupture and better functionality to the different bovine collagen hydrolysates.

title: Sex-Related Effects of Prenatal Stress on Region-Specific Expression of Monoamine Oxidase A and β Adrenergic Receptors in Rat Hearts

description: Abstract Background: Prenatal stress may increase risk of developing cardiovascular disorders in adulthood. The cardiotoxic effects of catecholamines are mediated via prolonged adrenergic receptor stimulation and increased oxidative stress upon their degradation by monoamine oxidase A (MAO-A). Objectives: We investigated long-term effects of prenatal stress on β (1, 2, 3) adrenergic receptors and MAO-A gene expression in the hearts of adult rat offspring. Methods: Pregnant rats were exposed to unpredictable mild stress during the third week of gestation. RNA was isolated from left ventricular apex and base of adult offspring. Quantitative PCR was used to measure gene expression in collected ventricular tissue samples. The level of significance was set to p &lt; 0.05. Results: β3 adrenergic receptor mRNA was undetectable in rat left ventricle. β1 adrenergic receptor was the predominantly expressed subtype at the apical and basal left ventricular myocardium in the control females. Male offspring from unstressed mothers displayed higher apical cardiac β1 than β2 adrenergic receptor mRNA levels. However, β1 and β2 adrenergic receptor mRNAs were similarly expressed at the ventricular basal myocardium in males. Unlike males, prenatally stressed females exhibited decreased β1 adrenergic receptor mRNA expression at the apical myocardium. Prenatal stress did not affect cardiac MAO-A gene expression. Conclusions: Collectively, our results show that prenatal stress may have exerted region- and sex-specific β1 and β2 adrenergic receptor expression patterns within the left ventricle.

title: Destruction of measurement scale through exploratory factor analysis in production and operations research

description: Abstract This paper aims to assess the use of Exploratory Factor Analysis by Production and Operations researchers, discussing the adequacy of its application. We analyzed 97 papers published between 2010 and 2015 in the Production and Operations area -- of which 61 and 36 were published in international and Brazilian journals, respectively. These papers contain 140 different applications of Factor Analysis. The research shows that confirmatory techniques are prevalent in international papers, as well as exploratory techniques to evaluate the problem of common method bias. Conversely, the papers in Brazilian journals typically use the exploratory technique in more traditional ways, such as to confirm the unidimensionality of the construct, or still to generate scores for use in other statistical techniques. Despite the textbooks for the AFE teaching focus exclusively on the use of AFE in the exploratory mode (to identify the number and meaning of the common factors), this use has been less frequent in published articles, both national and international. Moreover, the research shows that the inappropriate use of exploratory (rather than confirmatory) factor analysis in four Brazilian papers resulted in the “destruction of theory”. These findings suggest that national research have been using exploratory factor analysis in a questionable way; in this sense we propose scholars discuss this topic in order to disseminate the good practices.

title: Rearing two fruit flies pests on artificial diet with variable pH

description: Abstract Fruit flies (Diptera: Tephritidae) are considered the main fruit pests worldwide. In Brazil, two species are predominant: the South American fruit fly, Anastrepha fraterculus and the Mediterranean fruit fly, Ceratitis capitata. In this study, we evaluated the effect of artificial diets with variable pH in their larval development and adult performance. The experiments were carried out in the laboratory at 25 ± 2 °C, 70 ± 10% RH and 12:12h (L:D) photoperiod. Semisolid diets with pH values of 6.0, 5.0, 4.0, 3.0, 2.0, 1.5, and 1.0, adjusted by adding hydrochloric acid were tested. Results indicated that the diet with pH 6.0 did not support larval development of both species of fruit fly. Diets with greater acidic pH values did not allow egg, larvae or pupae development and adult reproduction of A. fraterculus. For C. capitata , the pH of artificial diet exerts greater influence compared to A. fraterculus on the duration and viability of the larval stage, number of pupae, sex ratio and longevity of males.

title: Increasing yoghurt daily production with modeling and simulation process

description: ABSTRACT: The objective of this research was to use the modeling and computer simulation to support decision makers, aiming to increase the productive capacity of the agro-industry of LaticínioFunarbe. Specifically, it has modeled the current yoghurt production sector for simulation that enables it to meet the new demand. The Arena 14.7 simulation software was used to conduct the modeling. To validate the model, the output of yoghurt production collected at the factory for three months was compared with the output from the simulated computational model. Two indicators were established to perform analyzes of four different scenarios. The implemented model resulted in an increase in the production capacity of 5,000L.d-1 of yoghurt, corresponding to a production of yoghurts processed daily three times higher than the current production.

title: The remarkable pioneering contribution of Gaspar Vianna to the study of the neuropathology of Chagas disease

description: ABSTRACT Gaspar Vianna is considered one of the great names in Medicine and Science in Brazil. Yet, little prominence has been given to his studies in Neuropathology. He was the first to describe, in 1911, the histopathology and pathogenesis of chagasic encephalitis in the acute phase of Chagas disease, as well as the intracellular life cycle of Trypanosoma cruzi. Over 100 years have elapsed and Gaspar Vianna's pioneering study remains an example of a meticulous and still up-to-date description of central nervous system involvement in the acute phase of Chagas disease.

title: Development of a fruit smoothie with solid albumen of green coconut

description: ABSTRACT: The present study aimed to develop a mixed smoothie drink using the solid albumen of the green coconut in its composition. Smoothie formulations were prepared following an experimental design, setting the solid albumen concentration at 20% and varying the contents of the acerola (Barbados Cherry), pineapple, and coconut water pulps, which corresponded to 80% of the total mass of the product. Response parameters evaluated were vitamin C content, antioxidant capacity, and overall sensory acceptance. Ten formulations were evaluated. The ones that contained higher concentrations of acerola pulp had higher values of bioactive compounds but were not the most sensorially accepted. By means of the desirability function, a final formulation consisted of 52.8% of pineapple, 27.2% of acerola, and 20.0% of solid albumen of green coconut. This new formulation was well accepted, with a grade (score) 7 (“good”). It represents a good nutritional contribution and a source of vitamin C which can contribute to add value to a co-product of the beverage industry.

title: EVALUATION OF DIRECT PHOTOLYSIS, ELECTROOXIDATION AND PHOTOELECTROOXIDATION FOR RHODAMINE-B DEGRADATION

description: Abstract The focus of this study is to evaluate the efficiency of oxidation processes in the treatment of a solution containing Rhodamine-B (RhB) used in various industrial applications. The advanced oxidation processes of electrooxidation (EO) and photoelectrooxidation (PEO) were used. At the same time, direct photolysis (DP) was also applied. Total organic carbon (TOC) reduction and color removal were evaluated. There was an efficient color removal when DP was performed, and the color removal efficiency was the highest when NaCl was used as supporting electrolyte for PEO and EO. However, the TOC reduction was low, indicating that the degradation of the color does not correspond to the pollutant mineralization.
