title: Diet selenium improves the antioxidant defense system of juveniles Nile tilapia ( Oreochromis niloticus L.)

description: Abstract From the advancement of tilapia production in recent years, diets are sought that allow the maximum growth, improving health and fish quality. In this study growth, biochemical, hematological and oxidative parameters were evaluated of tilapia fed with increasing selenium levels: 0.53, 0.86, 1.04 and 1.22 mg kg-1. It was used 400 juveniles (initial weight = 36.51 ± 10.88 g), fed for six weeks. There was no effect of selenium on fish growth, biochemical and hematological parameters. In the oxidative parameters, there was an increase in non-protein thiols and a decrease in malondialdehyde levels, evidencing antioxidant effects of selenium. The diet selenium levels above 0.86 mg kg-1 improved the antioxidant system and does not affect to biochemical, hematological and growth parameters of tilapia juveniles.

title: Study on assessment of proximate composition and meat quality of fresh and stored Clarias gariepinus and Cyprinus carpio

description: Abstract The organoleptic evaluation and proximate analysis of Clarias gariepinus and Cyprinus carpio were determined in fresh fish and when refrigerated at two different temperatures (-21 °C and 4 °C) for a period of six weeks. A panel of twelve trained judges evaluated the color (live), texture, softness and flavor of fish meat after two minutes’ steam cooking. Average score revealed a general decline in organoleptic properties such as color, texture, freshness, and taste of C. gariepinus and C. carpio stored at two temperatures compared to the fresh fish. Proximate analysis revealed a more decrease in crude protein and lipid contents and increase in ash content in C. gariepinus and C. carpio at the two storage temperatures compared to the fresh fish muscle. Moisture content decreased in the fish muscle samples of both the fish species stored at -21 °C but increased in the 4 °C stored samples. pH of fish was found to increase in the two stored temperatures. There were significant differences (P&lt;0.05) in the organoleptic and proximate composition of the ice stored and fresh C. gariepinus and C. carpio, the same temperature and between the two different temperatures. The quality of fish muscle stored at 4 °C deteriorated faster than that of the -21 °C. Thus, storage temperature and duration have adverse effects on the nutritional quality of fish meat.

title: Factors associated with the non-wear of mandibular dentures in the Brazilian public primary health care

description: Abstract This study investigated factors that affect the use of complete conventional mandibular dentures (CCMD) by patients of the Brazilian Public Health Service. For this, two hundred and thirty one subjects who received CCMD in the Primary Health Care of the Public Health Service in Belo Horizonte – Brazil were evaluated and divided in Group 1 – irregular/non-wear; Group 2 – regular wear. Multivariate logistic regression analysis was used to create predictive models for CCMD non-wear and included socio-demographic and biological variables, technical quality of CCMD, and user satisfaction. The prevalence of CCMD non-wear was 41.10%. The mean score of CCMD quality was 54.97 (0–100). Not wearing the CCMD was significantly associated with user satisfaction and technical quality (p &lt; 0.05). The lack of retention of the CCMD was the most important factor in the evaluation of satisfaction and quality. The final predictive model (specificity = 92.65%; AROC = 0.8759) for not wearing the CCMD retained the variables CCMD stability (OR = 0.888; 95%CI = 0.827–0.954), freeway space (OR = 0.916; 95%CI = 0.860–0.976), satisfaction with speech (OR = 0.694; 95%CI = 0.612–0.786), and irregular CCMD edges (OR = 3.185; 95%CI = 1.478–6.864). Socio-demographic and biological variables were not associated with patients not wearing the CCMD, whereas technical quality and user satisfaction were strongly associated.

title: Virulence genes in Escherichia coli isolates from commercialized saltwater mussels Mytella guyanensis (Lamarck, 1819)

description: Abstract The isolation of Escherichia coli from food is a major concern. Pathogenic strains of these bacteria cause diseases which range from diarrhea to hemolytic-uremic syndrome. Therefore the virulence genes in E. coli isolates from the mussel ( Mytella guyanensis) commercialized in Cachoeira, Bahia, Brazil were investigated. Samples were purchased from four vendors: two from supermarkets and two from fair outlets. They were conditioned into isothermal boxes with reusable ice and transported to the laboratory for analysis. E. coli strains were isolated in eosin methylene blue agar, preserved in brain-heart infusion medium with 15% glycerol and stored at -20 °C, after microbiological analysis. Virulence genes in the isolated strains were identified by specific primers, with Polymerase Chain Reaction. Twenty-four isolates were obtained, with a prevalence of elt gene, typical from enterotoxigenic infection, in 75% of the isolates. The stx and bfpA genes, prevalent in enterohemorragic and enteropathogenic E. coli, respectively, were not detected. The occurrence of elt virulence-related gene in the E. coli isolates of Mytella guyanensis reveals urgent improvement in food processing, including good handling practices, adequate storage and cooking before consumption, to ensure consumer’s health.

title: Phytophagous insects in cotton crop residues during the fallow period in the state of Mato Grosso do Sul, Brazil

description: Abstract: The objective of this work was to analyze the faunistic composition of the insect pests that occur during the fallow period in cotton (Gossypium hirsutum) crop residues in the state of Mato Grosso do Sul, Brazil. The study sites were the municipalities of Alcinópolis, Chapadão do Sul, Costa Rica, Aral Moreira, Dourados, and Sidrolândia. A sampling design with two replicates per municipality was used. Each replicate comprised 100 random points, and each point corresponded to a cotton plant that was entirely inspected, to count the insect pests on it. The obtained fauna was analyzed and a rarefaction curve of the species was generated. During the evaluation period, a total of 23 species were recorded in the cotton crop residue, and the most frequent and abundant were Bemisia tabaci, Aphis gossypii, Frankliniella schultzei, and Anthonomus grandis. The caterpillars were predominantly found on the non-Bt cotton crops in Dourados, and Chapadão do Sul was the municipality that exhibited the greatest species diversity. Despite being mandatory, the destruction of cotton stalks during the fallow period was not able to completely eliminate the insect pests during the study period; among these insect pests, A. grandis stands out, a species that affects the dynamics of cotton pest control.

title: Proline content of sunflower cultivars in the Brazilian semiarid region

description: Abstract: The objective of this work was to evaluate the proline content of sunflower (Helianthus annuus) cultivars, in the conditions of natural water deficit in the Brazilian semiarid region. Thirteen cultivars were sown in experiments set in three sites in the Brazilian Northeast. Proline content was determined on leaves from plants at the R4-R5 stage. Significant differences among cultivars occurred only where water availability was lower. Proline averages ranged from 3.47 to 17.41 μg g-1. The sunflower cultivars BRS387, BRS323, and BRS324 showed the greatest proline contents with 54.74, 46.27, and 35.16 μg g-1, respectively. These are the cultivars that accumulate more proline under conditions of a severe water deficit.

title: Analysis of the association between bladder carcinoma and arsenic concentration in soil and water in southeast Brazil

description: ABSTRACT In approximately 50% of cases of bladder carcinoma, an associated predisposing factor can be established. The main factors are exposure to tobacco, arsenic (As) ore and aromatic compounds. Arsenic is a metalloid with a low average concentration in the earth's crust, and one of the most dangerous substances for human health. The present study aims to evaluate the incidence of hospitalization and mortality from bladder neoplasia and its possible association with As concentration in water and soil in two of the most critical regions of Brazil: the states of São Paulo and Minas Gerais. We have investigated bladder cancer hospitalization and mortality in the states of Sao Paulo and Minas Gerais during 2010-2014. Water and soil samples were analyzed and As concentrations were established. Data were obtained through the Department of Informatics of the Brazilian Unified Health System. Correlation was made with water samples from São Paulo and with data on soil analysis from Minas Gerais. The results revealed no direct association in the distinctive municipalities. Areas with high environmental As concentration had a low bladder cancer rate, while areas with normal as levels had similar cancer rates. The quantitative variables did not present a normal distribution (p &lt; 0.05). In conclusion, we did not observe a correlation between as concentration in water or soil and bladder cancer's hospitalization and mortality rates in the states of São Paulo and Minas Gerais.

title: Medical Students’ Perceptions of the Brazilian Public Health System, expressed in a Reflective Portfolio

description: ABSTRACT The way of thinking about medicine courses, and the profile of future physicians in Brazil have changed since 2001, and this has affected the institutions and people involved in this process. This article analyzes medical students’ views on what is expected of them after graduation, and the new concept of physician expected by the public health care system in Brazil. It is a qualitative study, based on portfolios developed by students in their final period in the years 2013 and 2014. Analysis of the portfolios considered the expectations generated by the students’ expectations of medical schools in Brazil since 2001, i.e., to produce general physicians with a humanistic, critical, reflective and ethical training. The results revealed that most students think about the public health system, and know and understand how it is organized, but they do not identify themselves either with the scenario, or with the professionals who work within it. Regarding their role as students in this context, some students adopted the position of spectators, while others recognized how important they are in helping to change the system in line with SUS guidelines. Finally, the students believe that the ESF may work, but they do not feel part of this system and do not recognize the patients they meet there as their idealized patient.

title: In vitro propagation of Campomanesia rufa: An endangered fruit species

description: ABSTRACT The Campomanesia rufa is a fruitful species native from Brazil considered as endangered by the IUC (International Union for Conservation of Nature) and low information regarding its propagation is available. In this context, the aim of the present study was to develop in vitro germination, micropropagation and callogenesis protocols for the species. For in vitro germination, seeds were inoculated in MS medium supplemented with GA3 (gibberellic acid) and for shoot induction, the medium was supplemented with three different cytokinins BA (benzyladenine), BAP (6-Benzylaminopurine) or TDZ (Thidiazuron). For shoot growth, culture medium containing BA, BAP, TDZ were maintained under white fluorescent lamps and blue:red light-emitting diodes (LED). GA3 was also tested on in vitro shoot elongation. For oxidation control, the medium was supplemented with PVP (polyvinylpyrrolidone) and for callus induction, 2.4-D (dichlorophenoxyacetic acid). The results showed 68% germination regardless of GA3 concentration. In the propagation stage, BAP at 4.5 µM induced a higher number of shoots (4.53) and LED lamps as the light source combined with the culture medium with 1 μM BAP induced a higher number of shoots (4.08). The highest average of C. rufa length (31.9 mm) was obtained using 8.8 µM GA3. The use of PVP (584.3 uM) controls up to 27.3% oxidation in young leaf explants. The use of 10 µM 2.4-D leads to a higher callus formation (58.7 %). Therefore, it can be concluded that the use of BAP is efficient in the induction of shoots, PVP controls oxidation leaf segments, and 2.4-D induces callus in C. rufa.
