title: Factors that influence in Jatropha curcas L. latex production

description: ABSTRACT Latex from Jatropha curcas L. exhibits biotechnological potential for the development of biodiesel and drugs. Little is known about the collection methods and latex productivity of this species. In order to garner information on the use of J. curcas latex, factors that influence production by this species were assessed. As a result, no significant difference was found between the volume of latex collected in the stem and the branches. With respect to environmental characteristics, climatic conditions, such as low temperatures and rainfall, affected production. The period of low temperatures and leaf fall occurs after fruit harvest and, in the absence of strong sinks, the plant can use the assimilates to generate greater latex production. Multiple regression analysis demonstrated that latex production is positively associated with plant height and negatively associated with fruit production and other variables that maximize it. During the fruiting process the plant uses most of the assimilates for fruit development and a lower percentage to produce secondary compounds, resulting in less availability of these metabolites for latex production. In general, the latex production obtained from this species is low and limits commercial exploitation of this compound, despite its possible pharmacological potential.

title: Race/skin color and mental health disorders in Brazil: a systematic review of the literature

description: Abstract Mental health disorders contribute a significant burden to society. This systematic literature review aims to summarize the current state of the literature on race/skin color and mental health disorders in Brazil. Methods: PubMed and Lilacs were searched using descriptors for mental health disorders (depression, anxiety, Common Mental Disorders, psychiatric morbidity, etc.) and race to find studies conducted in Brazil. Studies of non-population groups, that did not analyze race/skin color, or for which the mental disorder was not the object of study were excluded. After evaluation of quality, 14 articles were selected for inclusion. There was an overall higher prevalence of mental health disorders in non-Whites. Of the six multivariate analyses that found statistically significant results, five indicated a greater prevalence or odds of mental health disorder in non-Whites compared to Whites (measure of association between 1.18-1.85). This review identified the trend in the literature regarding the association between race and mental health disorders. However, important difficulties complicate the comparability of the studies, principally in function of the differences in the mental health disorders studied, the method of categorizing race/skin color, and the screening tools used in the studies analyzed.

title: Impacts of climate change on drought: changes to drier conditions at the beginning of the crop growing season in southern Brazil

description: ABSTRACT The intensification of drought incidence is one of the most important threats of the 21st century with significant effects on food security. Accordingly, there is a need to improve the understanding of the regional impacts of climate change on this hazard. This study assessed long-term trends in probability-based drought indices (Standardized Precipitation Index and Standardized Evapotranspiration Index) in the State of São Paulo, Brazil. Owing to the multi-scalar nature of both indices, the analyses were performed at 1 to 12-month time scales. The indices were calculated by means of a relativist approach that allowed us to compare drought conditions from different periods. The years 1961-1990 were used as the referential period. To the authors’ best knowledge, this is the first time that such relativist approach is used in historical trend analysis. The results suggest that the evapotranspiration rates have intensified the regional drought conditions. The time scale used to calculate the indices significantly affected the outcomes of drought trend assessments. The reason behind this feature is that the significant changes in the monthly regional patterns are limited to a specific period of the year. More specifically, virtually all significant changes have been observed during the first trimester of the rainy season (October, November and December). Considering that this period corresponds to critical plant growth stages (flowering/regrowth/sprouting) of several major crops (e.g. Sugarcane and Citrus), we may conclude that these significant changes have increased the risk of crop yield reductions due to agricultural drought.

title: Chemical characterization of marine fish of low-commercial value and development of fish burgers

description: Abstract: The objective of this work was to perform the chemical characterization of marine bonefish (Albula vulpes) and the development of fish burgers. Three formulations of fish burgers were prepared, containing 5, 8, and 10% cassava starch and functional ingredients (onion, garlic, and ground white pepper). Proximate composition, microbiological and pH analyses of the raw material, and fish burgers were performed, as well as the sensory analyses of the fish burgers. The yield and nutritional value of bonefish was found to be comparable with those of species of commercial value, with high-protein and low-lipid contents. The protein content of the fish burgers varied from 17.52 to 19.40 g 100 g-1 (raw), and from 20.74 to 24.25 g 100 g-1 (grilled); and the lipid contents ranged from 0.20 to 0.73 g 100 g-1 (raw), and from 0.36 to 0.77 g 100 g-1 (grilled). In the sensory tests, the formulations received scores between six and seven on the nine-point hedonic scale. Acceptance indexes were higher than 70% for all the assessed attributes. Therefore, the use of this underutilized species proves to be feasible.

title: Production of biodegradable starch nanocomposites using cellulose nanocrystals extracted from coconut fibers

description: Abstract Different polymeric matrices have been investigated for use in the development of biodegradable films. The incorporation of cellulose nanocrystals in such films has particularly attracted attention because of the potential for achieving improved properties of starch nanocomposites. In the present study, cellulose nanocrystals were extracted from coconut fibers and incorporated in cassava and potato starch films at different concentrations. The properties of the different nanobiocomposite films were comparatively evaluated, including their barrier and mechanical properties. All the films, regardless of the nanocrystal concentration, were found to exhibit low solubility in water, with increased moisture content particularly observed in the films with higher nanocrystal concentrations. The potato starch film with the lowest nanocrystal concentration was found to exhibit the best mechanical properties. The observations of this study indicated that the source of the starch and the nanocrystal concentration determined the properties of the nanobiocomposite films.

title: Phosphate solubilization by endophytic bacteria isolated from banana trees

description: ABSTRACT Forty isolates of endophytic bacteria isolated from banana tree roots were assessed as to their capacity to solubilize phosphate in a solid culture medium supplemented with different inorganic and one organic source of phosphorus. The amount of phosphorus (P) in each liquid medium was quantified, and an indirect assessment of acid phosphatase activity was performed. All assays had a fully randomized design, with three repetitions. Approximately 67.5% of the 40 isolates assessed in solid medium solubilized phosphorus from tricalcium phosphate and 7.5% of the isolates solubilized phosphorus from soy lecithin; no isolates exhibited P solubilization capacity in medium supplemented with iron phosphate. Acid phosphatase activity was detected in 65% of the isolates; Aneurinibacillus sp. and Lysinibacillus sp. isolates presented with the best solubilization indexes. All of the assessed isolates exhibited a capacity to reduce the potential of hydrogen in liquid medium supplemented with tricalcium phosphate. Isolate EB. 78 (Bacillus sp.) exhibited P solubilization capacity in solid media when Ca3(PO4)2 and soy lecithin were used as P sources; this isolate significantly reduced the pH of the liquid medium and exhibited acid phosphatase activity. The results of the present study highlight isolates that exhibit variations in their capacity to solubilize P. These isolates should be used in future tests to assess their field performance.

title: LOOTING IN ARGENTINA: some clues for its comprehension based on the episodes of Córdoba – 2013

description: Continuing with a series of reflections that are situated between the studies of collective action, ideological criticism and the sociology of bodies and emotions, this study proposes to explain lootings in Argentina as phenomena associated with policies of particular sensitivities. In order to do this, this study revises the different ways of understanding the lootings; later, it reconstructs – from different secondary sources – an approximation of the “history of the spoliations” in Argentina, describing and establishing proximities and distances with the episode that occurred in Cordova in 2013. Finally, some possible interpretations of this episode are developed due to the analysis of qualitative material (observation and actors’ testimony). In the conclusion, it is emphasized the way in which lootings conceive the “unreason” of some particular practices of feeling, which can be described in the relationship between flow, mass, anger and vertigo. From there, some clues are synthesized for future analysis.

title: Health Academies Program and the promotion of physical activity in the city: the experience of Belo Horizonte, Minas Gerais state, Brazil

description: Abstract The objectives of this study were to describe the history and evaluation methodology of the Brazilian Health Academy Program (PAS) in Belo Horizonte, MG and discuss it as an experience of health promotion and equity. Data from 4,048 non-users (2008-09) and 402 users (2014-15) were analyzed from two cross-sectional surveys. Socio-demographic profile and level of physical activity were described for both groups. Social interaction, satisfaction with life, quality of life, and social organization in the neighborhood were compared between &lt; 3 and ≥ 3 monthly minimum wages income and conducted only for women aged 40 years and older . Chi-square test of Person was performed (p ≤ 0.05). Prevalence of leisure-time physical activity among non-users was of 30.2% and users of 53.7%. Better perception of quality of life, positive satisfaction with life, greater social interactions and participation in the neighborhood were observed among women with higher income compared to their counterparts (p &lt; 0.001). In turn, for all evaluated constructs, users reported better perception of the lower income group. The PAS has opportunized physical activity to the vulnerable population and seems to act on other outcomes besides the lifestyle.

title: Popcorn germplasm resistance to fungal diseases caused by Exserohilum turcicum and Bipolaris maydis

description: ABSTRACT Compared with the common corn, popcorn shows greater susceptibility to pests and diseases occurrence, being the use of resistant cultivars the most efficient strategy. In this regard, Germplasm Banks deserve special attention because they contain accessions that can be used as sources of resistance in breeding programs. The State University of Northern Rio de Janeiro (UENF) maintains a popcorn Germplasm Bank with accessions from tropical and temperate countries, including Diversity Centers for the species. In this study, we investigated the performance of 37 popcorn accessions landraces, hybrids, and inbreed lines ― from the Germplasm Collection of UENF’s Popcorn Breeding Program with respect to the fungal leaf diseases northern leaf blight (NLB) and southern leaf blight (SLB), caused by Exserohilum turcicum and Bipolaris maydis, aiming to select promising accessions for genetic resistance to be used in future crosses to generate new resistant cultivars for farmers. The dendrogram scattering by the UPGMA multivariate technique was efficient in discriminating resistant accessions. Satisfactory results were obtained for resistance to NLB in accessions L71, L75, L76, P7, and PARA-172, which can thus be considered remarkable sources of resistance. For resistance to SLB, the superior accessions that can be indicated as sources of resistance are ARZM-05083, ARZM-07049, and PARA-172.
