title: Characterization and application of Lippia alba (Mill) and Cymbopogon citratus D.C. Stapf. essential oils as natural sanitizers in coriander

description: Abstract Essential oils (EOs) are a promising alternative for food preservation and can be used instead of synthetic antimicrobial compounds such as sanitizers, as long as they are efficient and safe. In view of this possibility of use, Lippia alba (Mill) (LAEO) and Cymbopogon citratus D.C. Stapf. (CCEO) essential oils were evaluated as natural antimicrobials and applied into coriander for its biocontrol. The EOs were extracted and their physical properties, total phenolics, cytotoxicity to Artemia salina L. and antimicrobial potential in vitro and on natural coriander microbiota were determined. The EOs had a LD50 (median lethal dose - checked), are considered biologically active. MIC (Minimum Inhibitory Concentration) varied from 1.25 to 5.00 μL/ mL and from 0.62 to 5.00 μL/ mL for LAEO and CCEO, respectively, on standard strains of Staphylococcus aureus, Salmonella Thyphimurium, Salmonella Enteritidis, Escherichia coli and Listeria monocytogenes. The lowest MIC values for LAEO and CCEO were selected for application in coriander. EOs reduced the pathogenic microbial load in the coriander revealing its potential as a natural sanitizer, and thus demonstrating superior or equivalent efficacy to commercial sanitizer. By correlating the cytotoxic and antimicrobial results obtained, we have shown that these EOs present potential for application in foods.

title: Arterial stiffness in hyperthyroid patients is deteriorated due to thyroid hormones

description: ABSTRACT Objective The aim of this study is to evaluate and compare arterial stiffness, which is an independent risk indicator for cardiovascular diseases (CVDs), between patients with overt hyperthyroidism, subclinical hyperthyroidism, euthyroidism by antithyroid therapy and healthy volunteers with pulse wave analysis (PWA). Subjects and methods A total of 102 volunteers were included in the study (30 in the overt hyperthyroid group, 28 in the subclinical hyperthyroid group and 14 with euthyroidism by antithyroid therapy and 30 healthy). The arterial stiffness measurements of the participants in the study were performed with the Mobil-O-Graph PWA device (I.E.M. GmBH, Stolberg, Germany), which makes cuff based oscillometric measurement from the brachial artery. Results Systolic blood pressure, pulse rate, central systolic blood pressure, cardiac output, heart rate-corrected augmentation index (Aix@75) and pulse wave velocity (PWV) measurements were significantly higher in the hyperthyroid group than in the control group. The heart rate and PWV in the subclinical hyperthyroid group were significantly higher than the control group. In the euthyroid group, systolic blood pressure, central systolic blood pressure, cardiac output, cardiac index and PWV were found significantly higher than the control group. There was also a negative correlation between Aix@75 and thyroid-stimulating hormone (TSH), and a positive correlation between Aix@75 and free thyroid hormones. Conclusion In our study, we observed that the arterial stiffness was adversely affected by an overt or subclinical increase in thyroid hormones and this correlated with thyroid hormone levels. We recommend that PWV measurement, which is a simple method for detecting CVD risk, can be used in these patients.

title: Physicochemical and antioxidant properties of methanol extract from Maca (Lepidium meyenii Walp.) leaves and roots

description: Abstract In this study, we examined the phytochemical properties and antioxidant activities of the methanol extracts of maca (Lepidium meyenii Walp.) leaves and roots. A total of 25 chemical compounds were identified by LC-Q-TOF and classified as saponins, phenols, flavonoids, steroids, alkybenzenes, and amines. Among all the chemical compounds identified, three saponins (tanshinone I, panaxytriol, and rotundifolioside), one phenol (gingerol), and one steroid (ergosterol peroxide) were found in the both leaf and root extracts. Levels of saponins, phenols, and flavonoids in the methanol extract from maca leaves were significantly higher than in the extract of roots. Antioxidant activities (1,1-diphenyl-2-picrylhydrazyl radical scavenging activity and ferric reducing ability of plasma) of the methanol extracts of maca leaves were higher than those of the roots. Antioxidant activities were highly correlated with total phenol content in the methanol extracts of maca leaves. Therefore, the methanol extract from maca leaves exhibited higher antioxidant activities than those of roots, and could be used as a nutritional material with potential health benefits.

title: Who loses and who wins with the PEC 287/2016? An analysis of the pension wealth variation for the urban beneficiary of Brazilian Social Security System.

description: Abstract This study calculates the impact of the changes in the individual pension wealth due to the proposed constitutional amendment 287/2016 that provides on the retirement eligibility age, benefit replacement rate, benefit accrual formula, and reduced percentage of family benefits. It uses the expected cash flow in actuarial net present value for the contributions and benefits of voluntary retirement, disability retirement, and death pension, in addition to family benefits. The results show that the most affected, are those of almost full retirement age with little contribution time. However, surprisingly, for groups with a high contribution period (more than 29 years for men and 21 for women) and aged between 45 and 55 years for men and between 40 and 54 for women there is an actuarial wealth gain.

title: Income gap between service and industry sectors in Brazil: a decomposition analysis

description: Abstract The objective of this study was to analyze the income differential between the service and industry sectors in Brazil based on the PNADs for the years 2004, 2009 and 2014. First, the wage gap was analyzed between the sectors mentioned using the decomposition by Oaxaca and Blinder, followed by an analysis employing the RIF (Recentered Influence Function) regression method. The results suggest that in the average wage decomposition the wage gap remains favorable to service sector workers in the three years analyzed. However, the analysis of quantiles indicated that the income differentials between sectors was more favorable to the services sector between 2004 and 2014 for the 75th and 90th quantiles of the distribution. In the lower quantiles, however, these differentials were more favorable to the workers in the industry sector.

title: Financial liberalization and structural change: the Brazilian case in the 2000s

description: Abstract This paper discusses the relationship between financial integration and structural change based on a Minsky-Kregel approach. The motivation for this investigation derives from the fact that the opening of the Brazilian economy in the 1990s did not generate a structural change capable of increasing the weight of higher-technological sectors in the manufacturing industry. In theoretical terms we assume that financial liberalization in developing countries induces the loss in importance of the industrial sector in the productive structure, leading to an early deindustrialization process. In addition, it increases the external fragility and reduces the scope for developing countries to implement long-term economic policies to increase their potential output. In our econometric exercise applied to the Brazilian economy in the 2000s it was observed that financial integration and dependence on foreign savings, captured by an international liquidity proxy and dummy variables to incorporate the external financial instability in the period studied, reduced the share of Brazilian industry in GDP.

title: O Desenvolvimento Rural no Estado do Rio de Janeiro a partir de Uma Análise Multidimensional

description: Abstract: The small economic importance of agriculture for Rio de Janeiro state does not imply the absence of rural areas, but rather that the rural areas of the state are facing a reality where other functions of rural areas are present (leisure and tourism) and that this situation is capable of providing virtuous rural development processes. Thus, this article aims to analyze and compare the process of rural development in Rio de Janeiro state from multidimensional indicators of rural development, rescuing its determinants. In order to do that, an adaptation of the methodology proposed by Kageyama (2008) was carried out. The necessary data to construct the indicators were collected mainly in the Demographic and Agricultural Census of IBGE and the Ministry of Education. The statistical technique used was factor analysis and cluster analysis. The analysis pointed out the existence of a heterogeneous situation in terms of development in the rural area of Rio de Janeiro, i.e., regions where the development process has been virtuous and associated with the expansion of the manufacturing and services sector and other situations where the coffee and sugarcane cycles have led to the opposite situation.

title: Virulence factors and phylotyping of Escherichia coli isolated from non-diarrheic and diarrheic water buffalo calves

description: ABSTRACT: This study aimed to determine the virulence factors, phylogenetic groups, and the relationships between pathovars and phylogenetic groups of E. coli strains isolated from feces of buffalo calves. A total of 217 E. coli strains were obtained from feces after culture and were screened by PCR for detection of virulence factors EAST-1, enterohemolysin, Saa, CNF2, F41, F5, STa, intimin, Stx1 and Stx2. One hundred and thirty-four isolates were positive for one or more virulence factors: eighty-four from diarrheic animals, and fifty from non-diarrheic calves. The pathovars of E. coli identified in diarrheic feces were ETEC (F5+) (2/84), NTEC (16/84), STEC (20/84), EPEC (3/84), EHEC (3/84), and EAEC (EAST-1+) (33/84). Pathovars identified in non-diarrheic animals were NTEC (21/50), STEC (17/50), EHEC (1/50) and EAEC (7/50). E. coli strains positive for EAST-1 (P=0.008) and phylogroup C (P = 0.05) were associated with the presence of diarrhea. Phylogenetic analysis showed that 58.95% of the isolates belonged to phylogroup B1, followed by E (9.70%), B2 (5.90%), C (5.90%), D (5.22%), A (2.24%), and F (1.50%). Phylogroup B1 predominated in pathogenic E. coli isolated from water buffalo, and phylogroup C constituted an enteropathogenic E. coli for water buffalo calves.

title: Ubiquitous work in post-graduation stricto sensu in education: in/extensification and multi-tasking

description: ABSTRACT The work of university teaching mediated by digital and mobile technologies increasingly gains in ubiquitous activity, with its paradoxical repercussions that affect two elements common to all human activities: time and space. Public-private boundary overflows and the incorporation of the modus operandi of productive restructuring into policies for regulation and evaluation of Brazilian post-graduation studies create tensions in various aspects of the work of university teaching. Based on an investigation conducted among professors at 48 doctorate education courses, we analyze the trends toward ubiquitous work, in a context in which work and education are under severe attack by government policies. The analyses indicate an intensification of the multi-tasking character of the work and of the in/extensification of the work to other times and spaces, which redesigns and compromises the intellectual work of the researchers.

title: Financial cycles and the credit market in Brazil during the 2000s

description: Abstract This study aims to analyze the behavior of Brazilian state-owned banks during the global financial crisis and its aftermath. In this regard, it employs time-series econometrics, based on the MS-DR and VEC models. Evidence was found suggesting that the credit originated in state-owned banks showed counter-cyclical characteristics; while private banks behaved in a typically procyclical manner.

title: Citric acid production by Aspergillus niger AN 400 from agroindustry waste

description: ABSTRACT The agro-industry generates large volumes of waste with high organic load, which requires the development of technologies to minimize the impacts caused by the improper disposal of this waste on the environment. The citric acid produced by agro food wastes as substrate for fermentation is a solution to reduce the organic load of these pollutants and add economic value by generating a profitable product. Aspergillus niger AN 400 was used to produce citric acid from cheese whey. The study was divided in three phases according to the addition of extra sugar (50, 100, 150 g.L-1): Phase I, with glucose; Phase II, with sucrose, and Phase III, with cheese whey only, without adding extra sugar. The reactors remained under agitation 150 rpm and at 30ºC for 10 days. The highest concentration of citric acid (2,379 mg.L-1) was observed upon the addition of 100 g.L-1 of glucose. However, the greatest yields were recorded in the reactors with 50 (458 mg.L-1.day-1) and 100 g.L-1 (745 mg.L-1. day-1) of sucrose, followed by the reactor that contained only cheese whey, without adding extra sugar (313 mg.L-1.day-1), demonstrating the potential of this waste to obtain citric acid with a great commercial interest.
