title: Spatial and temporal trends in freshwater fish research: the case of three neotropical river basins from Goiás State, Central Brazil

description: Abstract Aim In this paper, we conducted a scientometric analysis on published studies related to freshwater fish species at Goiás State to evaluate: i) their spatial and temporal trends; ii) areas of knowledge; iii) scientific journals where these papers were published and their comprehensiveness; iv) the role of institutions and financial support on fish research. Methods Using Google Scholar and Lattes platform, we searched for scientific papers related to freshwater fish, and we extracted the following information of each paper: title, author and co-authors’ name, number of authors, year, authors and co-authors’ affiliation, journal, field/area of the research, and financial support. Results We found 322 scientific papers related to Goiás State with a slightly growth in the number of publications over time. Most of these papers are related to Ecology, Systematic/Taxonomy and Fish Biology, and the participation of local institutions in these studies was mainly concentrated in Paraná River basin. Although most of funding were granted by agencies or institutions located outside Goiás State, the results showed that fish papers achieved a broad audience with publications in national and international journals with impact factor. Conclusions Our study revealed that: 1) freshwater fish research at Goiás State has a slow increase trend; 2) there are gaps in Education, Conservation and Fisheries knowledge areas; 3) local institutions’ contribution is spatially concentrated; 4) studies achieved a broad audience with many scientific papers published in journals with impact factor; 5) financial support was granted in most part by agencies or institutions located outside Goiás State. These findings suggest that despite achievements in freshwater fish research in this region, local investments in infrastructure, materials and human resources are still necessary to improve the production of studies.

title: Anthracnose intensity and physical and chemical characteristics of ‘Prata anã’ banana under different nitrogen doses

description: Abstract The balanced supply of nitrogen to fruit trees leads to higher fruit quality and reduced incidence of diseases. The aim of this study was to evaluate anthracnose intensity and the physical and chemical characteristics of ‘Prata Anã’ banana under different nitrogen doses. Regarding anthracnose intensity, N doses of 150, 200, 250, 400 and 600 kg ha-1 were used. The Area Under the Incidence Progress (AUIPC) and Severity Curves (AUSPC) were evaluated. The physical and chemical characteristics were: fruit and pulp mass; soluble solids; starch; total, reducing and non-reducing sugars; coloration and nutrient concentration in peel, evaluated every three days for 15 days. Plants fertilized with N doses of 200, 250 and 400 kg.ha-1 had lower AUIPC values and the application of 250 kg.ha-1 reduced AUSPC in fruits inoculated with C. musae. N, P and K increased in banana peel, fruit and pulp mass, soluble solids, starch, total sugars, reducing sugars, with increasing N doses. There was no difference in the contents of micronutrients in fruit peel. N dose of 600 kg.ha-1 reduced the shelf life of fruits and provided higher sugar content and higher disease severity.

title: What Has Changed in the Dental Prosthesis Procedures in Primary Health Care In Brazil?

description: Abstract The study aimed to identify the changes in the provision of dental prosthetics procedures in the Brazilian primary care. Secondary data from the Brazilian “National Programme for Improving Access and Quality of Primary Care” was assessed and three similar questions related to dental prostheses execution that were answered by the same 9,698 oral health teams, in 2011/2012 and 2013/2014, were compared. There was a 4.3% increase in the number of teams that identified individuals with prosthetic needs; a 0.8% increase in the number of teams that performed impression for prosthetic purposes; and the number of teams that reported performing dental prostheses consultations increased by 0.6%. Overall, there was a small modification in the number of teams that provided dental prosthesis procedures in Brazil.

title: Fruit flies (Diptera: Tephritidae) in commercial mango orchards in a semiarid region of Brazil

description: Abstract Fruit flies (Diptera: Tephritidae) are important mango (Mangifera indica L.) pests in several parts of the world. Therefore, the main objective of this study was to know the species of fruit flies associated with commercial mango orchards in a semiarid region of Rio Grande do Norte state, Brazil; report the species of quarantine importance; discuss the influence of the semiarid environment on the distribution of the species and verify their faunistic indices. The study was carried out between July 2011 and June 2014 in ten commercial orchards of mango cultivar Tommy Atkins in the semiarid region of the state of Rio Grande do Norte, Northeastern Brazil. Fruit flies were captured in McPhail traps baited with 5% hydrolyzed corn protein (Bio Anastrepha®). Mangoes fruits were also collected. Faunistic analysis was performed to characterize the populations. Eight fruit fly species (Anastrepha spp. and C. capitata) were captured. The species C. capitata had the highest geographic distribution and was the only one to infest mangoes. The faunistic analysis showed that most of the orchards had low species richness and that C. capitata was the most frequent and predominant species.

title: Influence of Pre-Heating Regular Resin Composites and Flowable Composites on Luting Ceramic Veneers with Different Thicknesses

description: Abstract The aim of this study was to evaluate of pre-heating, filler contents and ceramic thickness on film thickness, microshear bond strength, degree of conversion and color change on ceramic veneers. Two experimental composites were prepared (Bis-GMA/UDMA/BisEMA/ TEGDMA), with different amounts of filler (65% or 50%wt) simulating a conventional and a flowable composite. The flowable (F) was used at room temperature and, the conventional either at room temperature (C) or pre-heated (CPH). Disk-shaped ceramics with different thickness (0.4 mm, 0.8 mm, 1.5 mm) were prepared. The film thickness was evaluated according to the ISO 4049 (n=10). The microshear bond strength (n=10) was evaluated in enamel using tubing specimens light-cured through the ceramic veneer. The degree of conversion was evaluated using Raman spectroscopy. The color change of the ceramic restorations (n=10) was evaluated by spectrophotometry. The results were submitted to 2-way ANOVA and Tukey’s post hoc test (a=5%). For the film thickness 1-way ANOVA was used (a=5%). The C presented the thicker film thickness; the CPH produced a similar film thickness in comparison to the F. All composites showed similar microshear bond strength. The degree of conversion of the F was higher than the C and CPH. The degree of conversion of the composites photo-activated through a 0.4 mm was higher than the composites photo-activated through thicker ceramics. The C showed the highest color change, while the CPH showed similar color change to the F. In conclusion, pre-heated conventional composites seem to be a potential alternative to lute ceramic veneers such as the flowable composites.

title: The Wear Performance of Glazed and Polished Full Contour Zirconia

description: Abstract This study evaluated the influence of zirconia surface finishes on the wear of an enamel analogue. 40 zirconia discs were divided into four groups: control (without finish); glazed; polished; polished and glazed. All samples were subjected to wear against steatite antagonists. The specimens underwent roughness, topographic, scanning electron microscopy (SEM) and wettability analyses. Quantitative wear measurements were performed on both steatites and discs. To measure wear of steatites the weight before and after the test and the diameter after the test were used. Profilometer measurements were performed to determine the wear on discs. Roughness, volumetric wear and mass loss were analyzed using the Kruskal-Wallis and Dunn tests (5%), while contact angle values were analyzed with One-way ANOVA and Tukey tests (5%). The polished group had the lowest roughness means, being statistically different from the other groups (p-value=0.0001). The glazed group presented the lowest steatite volumetric wear (p-value=0.0001), but not statistically different from the polished and glazed group, whereas these groups presented the highest zirconia volumetric wear, with statistically different (p-value=0.0002) compared to the others. SEM showed irregularities on the control groups surface, grooves on the polished group, and a homogeneous surface for the glazed group with a few pores. All groups presented contact angles lower than 90 degrees, characterizing hydrophilic surfaces. It can be concluded that just glazed zirconia caused less wear on the antagonist when compared to no finish and polished zirconia.

title: Generation, treatment and final disposal of the waste of water treatment stations in the state of Pernambuco, Brazil

description: ABSTRACT This article deals with the generation, quantification and final disposal of the sludge generated at existing Water Treatment Plants (WTPs), operating in the state of Pernambuco. The research was carried out in the period between January 2015 and December 2016 by the collection, systematization and interpretation of data that showed 246 WTPs that generate residues, of which 69 in decanters and filters, 176 only in the filters and one in the desalination system. The largest number of conventional WTPs is in the metropolitan region of Recife and the highest production of sludge was observed in the Capibaribe river basin, which receives a load of between 50 and 50,000 kg / (m3day). It was verified that approximately 75% of the state’s WTPs discard their residues in water bodies and 22% in the soil, without any kind of treatment. Only 3% perform the degassing process, yet discarding the solid mass in the soil, without any control at the final disposal of the same.

title: Systemic Effects (Risks) of Water Fluoridation

description: Abstract Since the 1950s, the benefits and risks of fluoridated water use have been debated worldwide. In the past, it was considered that the systemically ingested fluoride would exert its primary preventive effect after being incorporated into the enamel as fluorapatite, making the enamel more resistant to the caries process; however, it is now recognized that the main effect of water fluoridation is local and post eruptive. On the other hand, irrespective of the caries decline reported worldwide, the anticaries benefit of water fluoridation continues to be observed even in developed countries. Regarding the risks, water fluoridation is considered an acceptable community-based method for fluoride delivery, because the risk of developing dental fluorosis lesions due to the ingestion of fluoride during the enamel formation period has been deemed acceptable when contrasted to the anticaries benefits of fluoride. However, the use of fluoride in water to control caries has created a controversy due to data associating water fluoridation as the cause of some systemic diseases. Therefore, the aim of this descriptive review was to discuss the systemic effects (risks) of water fluoridation use.

title: Influence of the geotextile blanket and sludge height in anaerobic sludge dewatering using drainage bed

description: ABSTRACT Sewage Treatment Plants generate sewage sludge, which has approximately 95% of water and requires a proper disposal. Thus, dewatering is fundamental in sludge’s management since it promotes volume reduction of the residue. The drainage bed (DB) is a natural system, without the use of energy and chemicals, with prosperous results for the dewatering of sludge from Water Treatment Plants. In this sense, this research aimed to evaluate sewage sludge’s dewatering from Upflow Anaerobic Sludge Blanket (UASB). The analysis was performed through nine tests in DB models from laboratory scale with a bottom area of 31 × 31 cm. The tests were performed with three different geotextiles blankets: HaTe 55/55; 80/80 and 105/105 DW and three heights of applied crude sludge: 10, 15 and 20 cm. In the tests, the crude sludge’s initial solid content was measured. Then, at predetermined time intervals were measured: drainage flow, drained volume, apparent color, turbidity, pH and drained liquid’s conductivity. The tests with the HaTe 55/55 geotextile blanket obtained the best performance, with final reduction of the sludge volume above 65%, independent of the height of the sludge applied. The color and turbidity results of the drained liquid for the HaTe 55/55 geotextile blanket showed a tendency to improve quality with the increase of the sludge height, a fact not observed for the other geotextiles blankets.

title: Azithromycin and Full-Mouth Scaling For the Treatment of Generalized Stage III and IV Periodontitis: A 6-Month Randomized Comparative Clinical Trial

description: Abstract The effectiveness of azithromycin combined with full-mouth scaling procedures was compared to quadrant-wise scaling combined with the same dosage of azithromycin when treating periodontitis patients over a 6-month period. In this randomized clinical trial study, thirty-four individuals diagnosed with generalized stage III and IV periodontitis underwent baseline, 3-month, and 6-month post-treatment examinations. The study population was randomly assigned to either full-mouth scaling (FMS) or quadrant-wise scaling and root planning (QSRP) in addition to their taking of systemic azithromycin (500 mg/day) for three consecutive days. Periodontal probing depth (PD), clinical attachment level (CAL), gingival index (GI), and plaque index (PI) were monitored along with the quantification of total bacterial load and red complex bacterial species (Porphyromonas gingivalis, Tannerella forsythia, and Treponema denticola) in subgingival samples by real time polymerase chain reaction. The volume of gingival crevicular fluid (GCF) was also monitored over time. The primary outcomes included improvements of PD and CAL. Data was statistically analyzed through a repeated-measures analysis of variance (ANOVA) test, multiple least significant difference (LSD) comparisons, Kruskal-Wallis, Friedman, and paired Student t-tests (p&lt;0.05). FMS and QSRP provided similar PD, CAL, GI, PI, and GCF improvements. After treatment, the FMS group displayed lower mean values of total bacterial load and red complex bacterial species in comparison to the QSRP group. FMS and QSRP in conjunction with systemic azithromycin appeared to be an effective and reliable short-term therapeutic approach for the treatment of generalized stage III and IV periodontitis. However, FMD demonstrated superiority in regard to the 6-month antibacterial effects when compared to QSRP.
