title: Nexus of exclusion and challenges for sustainability and health in an urban periphery in Brazil

description: The urban nexus approach involves the investigation and elucidation of integrated solutions through the recognition of tradeoffs between water, energy, and food, namely resources whose shortage leads to inequalities in health. The article’s central hypothesis is that the context of shortage corroborates social practices that can be synergic or contradictory in relation to the challenges of sustainability and social rights. The objective is to investigate synergies and contradictions based on social practices in the urban nexus in the neighborhood of Novo Recreio in the city of Guarulhos, Greater Metropolitan São Paulo, Brazil. The methodology consists of a qualitative ethnographic study drawing on practice theory as the reference, with direct field observations and narratives. The results featured social practices associated with systematic lack of water, precarious public lighting and transportation, and difficult access to fresh and healthy foods. The study of social practices between synergies and contradictions allowed verifying that this spontaneous process of search for solutions to local problems reveals the need to incorporate local practices and knowledge into public policies and global demands. We define nexus of exclusion as the peripheral condition of impossibility of conscious options that allow jointly orienting the reduction of shortage and iniquities through alternatives for sustainability.

title: Analysis of the agricultural productivity of the sugarcane crop in regions of new agricultural expansions of sugarcane

description: Abstract The launching of biofuel vehicles in 2003 led to ethanol demand increase and a new phase of expansion of sugarcane cultivation in Brazil. Although the increase in area of production and the quantity of sugarcane produced have been very important to Brazilian agribusiness, the recent agricultural productivity rate has slowed. In this context, this article analyzed the factors that influence the growth rate of sugarcane productivity in the regions of new agricultural expansions, specifically in the states of Mato Grosso do Sul and Goias. For the collection and data analysis, we used bibliographical and documentary research. The shift-share method was used to analyze the evolution of sugarcane production, through the decomposition of this variable into two factors: area effect and productivity effect. The results show that the increase in production in the region under analysis was mainly due to the incorporation of new planting areas and not to an increase in productivity. In addition, structural factors have negatively impacted crop performance. The analysis indicates that there is a slow rhythm of sugarcane fields’ renovation and the adoption of old varieties. Although the mechanization index is high in the studied regions, difficulties of technological adaptation still provide deficiency in the agricultural performance of sugarcane.

title: CHEMICAL CONTROL OF ASIAN SOYBEAN RUST AS A FUNCTION OF CULTIVAR, ROW SPACING AND SPRAY BAR SUPPORT SYSTEMS

description: ABSTRACT Product deposition and foliar surface cover are highly impacting factors on the efficiency of foliar fungicides applied to soybean cultivars, due to their low mobility, with side effects on Asian soybean rust (ASR) control. Spray bar support systems, such as the air curtain (Vortex®) and the use of nozzles along the bar (Dropleg®), stand out as an alternative to obtain a better distribution of fungicide throughout the plant. In this study, two spray bar support systems (Vortex® and Dropleg®) were, therefore, evaluated and compared with the conventional spraying method based on the biological efficacy in ASR control. In order to do this, two harvests, with three spacing between rows and two cultivars were employed. Vortex® and Dropleg® spray bar support mechanisms do not effectively contribute to the optimization of Asian soybean rust control or to the grain crop yield, regardless of cultivar and row spacing. Decreasing the row spacing did not influence the level of control of Asian soybean rust, as the highest grain yield was obtained with the smallest spacing. The cultivar with genetic resistance to Asian rust showed lower levels of this disease, thus, greater control against the use of fungicides.

title: GLA Gene Mutation in Hypertrophic Cardiomyopathy with a New Variant Description: Is it Fabry's Disease?

description: Abstract Background: Fabry disease (FD) is an X-linked lysosomal storage disorder caused by mutations in the alpha galactosidase A gene (GLA) that lead to the enzymatic deficiency of alpha galactosidase (α-Gal A), resulting in the accumulation of globotriaosylceramide (Gb3) and globotriaosylsphingosine (lyso-Gb3), causing multiple organ dysfunctions. Objective: To perform GLA gene screening in a group of patients with echocardiographic diagnosis of hypertrophic cardiomyopathy (HCM). Methods: a cross-sectional study was conducted with HCM patients from a university hospital. Patients with coronary artery disease and valvulopathies were excluded. Mutation analysis of the GLA gene was performed. In male subjects, the analysis was performed after evidence of low α-Gal A activity. Results: 60 patients with echocardiographic diagnosis of HCM were included. Age ranged from 12 to 85 years and 60% were women. Mean myocardial fibrosis percentage on MRI was 10.7 ± 13.1% and mean ventricular thickness was18.7 ± 6.7 mm. Four patients had the following GLA gene mutations: c.967C&gt;A (p.Pro323Thr), not yet described in the literature; c.937G&gt;T (p.Asp313Tyr); and c.352C&gt;T (p.Arg118Cys). All patients had normal levels of lyso-Gb3 and non-ischemic myocardial fibrosis on magnetic resonance imaging; one patient had proteinuria and one patient had ventricular tachycardia. Conclusion: in this study, the frequency of mutation in the GLA gene in patients with HCM was 6.7%. A novel mutation in exon 6 of the GLA gene, c.967C&gt;A (p.Pro323Thr), was identified. Patients with HCM may have GLA mutations and FD should be ruled out. Plasma (lyso-Gb3) levels do not seem to be sufficient to attain a diagnosis and organ biopsy should be considered.

title: Floral phenology, seed germination and hybrid plants of the Amerindian yam (Dioscorea trifida)

description: ABSTRACT The Amerindian yam (Dioscorea trifida) is a food plant native to the Amazon region. Several local varieties are cultivated by traditional family farmers for consumption and local trade. However, socioeconomic processes may be causing species genetic erosion. Knowledge about species sexual reproduction is essential for its conservation and genetic improvement. The objective of this study was to observe the floral phenology, to assess the germination and dormancy of seeds, to conduct controlled pollinations and to select hybrid plants of D. trifida with agronomic potential. Seed dormancy was confirmed and was broken by after-ripening at 28 oC and 80% RH. We carried out controlled pollinations between local landraces and cultivated the resulting hybrid plants in the field. The new genotypes showed high phenotypic variability and tubers with new characteristics, which permitted the selection of genotypes with agronomic potential for further studies. The results contribute to the conservation of agrobiodiversity and genetic improvement for added value of Amazonian native food plants.

title: Does Mean Platelet Volume Decrease in the presence of Coronary Artery Fistula?

description: Abstract Background: Coronary artery fistula (CAF) is an abnormal connection that links a coronary artery to a cardiac chamber or another major blood vessel. Several studies have shown the association between mean platelet volume (MPV) and cardiovascular diseases. In the literature, there is no previous study about the association between hematologic parameters and congenital CAF. For this reason, we aimed to investigate the association of MPV with CAF. Methods: 70 patients with normal coronary arteries and 50 with coronary artery fistulas were included. Routine blood and biochemical parameters were measured before the arteriography. Differences between groups for continuous variables were analyzed with t- test or Mann-Whitney test. P values &lt; 0.05 were considered significant. Regression analysis was used to find independent predictors of CAF. Results: Baseline patient demographics, including age and clinical risk factors, were similar between the groups. Compared to the control group, median (IQR) High-density lipoprotein cholesterol (HDL) levels were significantly higher (p=0.04) and MPV levels were significantly lower in the CAF group (8.84 ± 1.71fL vs. 10.43 ± 1.34, p &lt; 0.001). In the multivariate analysis, only MPV was a significant predictor of CAF (p &lt; 0.001, 95% CI for OR: 0.438 (0.306-0.629). A negative correlation was found between MPV and fistulae in Pearson's correlation test (r: -0.454, p &lt; 0.001). An MPV level of &lt; 9,6 fL showed sensitivity, specificity, positive predictive value and negative predictive value of 80%, 68%, 71% and 78% respectively (AUC = 0.766, 95% CI, 0.678-0.854) for the prediction of CAF. Conclusion: The present study suggests that MPV may decrease in patients with CAF.

title: Tuning Emitting Color of Electroluminescent Devices Containing Tris(2-acyl-1,3-indandionate)aluminum(III) Complexes as Emitting Layers

description: In this study, a novel type of tris(2-acyl-1,3-indandione)-aluminum(III) coordination compounds of the general formula [Al(acind)3]H2O, where 2-acyl-1,3-indandione (acind), 2-acetyl-1,3-indandione (aind), 2-benzoyl-1,3-indandione (bind), and 4-methyl-2-benzoyl-1,3-indandione (mbind), were synthesized and characterized by elemental analysis (CHN), Fourier transform infrared (FTIR) and nuclear magnetic resonance (1H NMR) spectroscopies, thermal analysis (TG/DTG and DTA), and optical absorption spectroscopy in the UV-Vis region. These compounds present remarkably high green luminescence in powder and in thin-film forms. However, when these compounds are applied in glass/ITO/β-NPB/spiro-2CBP/[Al(acind)3]/Al and glass/ITO/β-NPB/[Al(acind)3]/LiF/Al electroluminescent devices, where spiro-2CBP is 2,7-bis(carbazol-9-yl)-9,9-spirobifluorene and β-NPB is N,N’-bis(naphthalen-2-yl)-N,N’-bis(phenyl)-benzidine, the emission color tuned from green to red, reflecting a change from the direct charge recombination in the emitting layer of the [Al(acind)3] complexes to an exciplex-based emission in which [Al(acind)3] complexes and spiro 2-CBP acted as acceptor and donor, respectively. These results suggest that [Al(acind)3] complexes have potential applications as molecular light converter materials for fabricating new electroluminescent devices.

title: Evaluation of wastewater treatment plant with anaerobic reactor receiving sludge from water treatment plant Actiflo ®

description: ABSTRACT The objective of this paper was to analyze the disposal of decanter’s sludge from a WTP with microsand ballasted sedimentation (Actiflo®) in a WWTP containing UASB reactors and polishing pond, in Ponta Grossa - PR. The WWTP Verde operated in stable condition, with an average flow tributary of 213.14 L.s-1. The UASBs operated with HRT in 9.9 hours, VHL in 2.4 m3.m-3.d-1 and OLR ranging from 0.75 to 1.66 kgCOD.m-3.d-1. The polishing pond operated with HRT in 4.5 days and OLR ranging from 765 to 2872 kgCOD.ha-1.d-1, which corresponds from 19 to 72 gCOD.m-3.d-1. The efficiency of COD and TSS removal was maintained even with the release of WTP sludge. WWTP’s efficiency ranged between 80% and 86% for COD removal and between 92% and 96% for TSS. It was concluded that the release in the sewage collection network is a viable alternative to disposal of the decanter’s sludge from WTP Actiflo®.
