title: Study of physico-chemical properties in the evaluation of adsorption in biochar produced from leaves of amendoeira-da-praia

description: ABSTRACT This study evaluated the physical-chemical properties of the adsorption process in biochar produced from dry leaves of beach-almond, Terminalia catappa, as a useful tool for remediation purposes in water contaminated with metals. The biochar was characterized by having: bands of O-H, CH2, C-O, and C-O-C; contents of 48.8% carbon, 46.6% oxygen, 3.3% hydrogen and the others between sulfur and nitrogen; the presence of macropores; and being sieved (100 mesh). Parameters such as pH, equilibrium time and adsorption capacity by the Langmuir and Freundlich isotherms were determined from experiments using a radiotracer cocktail (Co-57, Mn-54 and Zn-65) which was added to deionized water and a constants mass of biochar. The high-purity germanium detector (HPGe) was used to quantify the radiotracer activity by gamma spectroscopy. The results showed better adsorption from pH 3.8 and 30 minutes equilibrium time. The Langmuir and Freundlich isotherms had a good model fit, with n values higher than 1, and showed affinity between the metals and the biochar. The adsorption capacities of Zn-65, Co-57 and Mn-54 were 1.273 ng.g−1, 3.271 ng.g−1 and 9.026 ng.g−1, respectively.

title: Life satisfaction and health self-assessment of older adults assisted through home care

description: ABSTRACT Objective: to identify sociodemographic and health characteristics according to age groups and to analyze the association between self-assessed health status and satisfaction with regular/bad life with sociodemographic characteristics, global functioning and falls of older adults linked to home care within the primary health care network. Method: cross-sectional study with 124 older adults, conducted using home interviews. A sociodemographic data and health status questionnaire was used, together with Barthel Index, Lawton Instrumental Activities of Daily Living Scale (IADL), the Mini-Mental State Examination, the Geriatric Depression Scale and the Timed Up and Go Test. Bivariate and multivariate analyses (Poisson regression) were applied. Results: there was a predominance of female octogenarians. Self-assessment of regular/bad health was associated with mild (p=0.002) and severe (p&lt;0.001) depressive symptoms. Satisfaction with regular/bad life was associated with fear of falling (p=0.019) and with mild (p&lt;0.001) and severe (p&lt;0.001) depressive symptoms. Conclusion: depressive symptoms were associated with a worse life satisfaction and health self-assessment.

title: Resistance training with blood flow restriction and cognition in elderly women (project “forte-mente-ativa”): study protocol

description: Abstract Aim: In the process of aging, there is a decrease on muscle strength and cognitive function. Resistance training combined with blood flow restriction (BFRRT) has been shown capable of maintaining or improve aspects of physical health. However, the effects of BFRRT the cognitive function of the elderly are not clear. This study aimed to describe the design of a randomized controlled clinical trial, that will investigate the effects of BFRRT on cognitive function, physical performance and physiological and morphological aspects in elderly women. Methods: Forty participants will be randomized into one of the following groups: low load resistance training, blood flow restriction resistance training, moderate load resistance training or Control. All intervention groups will complete 16 weeks of resistance training, three times week (45 minutes each), with training consisting of four exercises for the upper and lower body, including three sets of ten repetitions each. No exercise will be performed by the Control group. Cognitive function will be the primary outcome of the study. Secondary outcomes will include body composition, muscle strength, functional capacity, double-task, level of physical activity, static and dynamic balance, brain activity, BDNF neurotrophic factor, anxiety, depression and sleep state). Conclusion: This project will contribute to the existing knowledge and will have a social impact regarding the use of physical exercise as a non-pharmacological tool for the mental and physical health older individuals.

title: INSIGHT INTO THE CONFORMATIONAL SPACE OF N-BENZYL-N-(FURAN-2-YLMETHYL)ACETAMIDE BY NMR SPECTROSCOPY AND DFT CALCULATIONS

description: In this study, the conformational behavior of N-benzyl-N-(furan-2-ylmethyl) acetamide in chloroform was addressed by using a combined experimental/theoretical strategy using NMR spectroscopy and quantum chemical calculations. The 1H and 13C one-dimensional NMR spectra, as well as the two-dimensional HSQC-DEPT and HMBC-DEPT NMR spectra, evinced the presence of a hindered cis(E)-trans(Z) rotational equilibrium in solution. DFT calculations were performed at different theoretical levels using the polarizable continuum model (PCM) and predicted nine (four Z and five E structures) stable conformations. The interconversion dynamics among the different confirmations were established in terms of four different rotational equilibria in CDCl3. The chemical shifts in the 1H and 13C NMR spectra of the compound are similar to the values calculated for the two most abundant conformational equilibria at room temperature, one caused by two Z rotamers and the other by two E rotamers. The compound was also characterized for the first time by FTIR, Raman spectroscopy, and GC/MS spectrometry. Additionally, several acylation methodologies for synthesizing the title compound from N-benzyl-1-(furan-2-yl)methanamine were tested which resulted in high yields (&gt; 90%) under very convenient conditions (10 min, at room temperature).

title: Situation of study (SoS) on health education implemented in a co-creation (CoC) process

description: ABSTRACT Situation of study (SoS) has been reported as an excellent strategy to promote students’ significant learning. This work intended to demonstrate how a SoS on health education (“Knowing cancer: a way to life”) can be implemented within the co-creation (CoC) framework. The study was carried out in a middle school, with the participation of five groups: students (14-15 years old), teachers, future teachers, university teacher trainers and health professionals. The 10 activities were carried out in school and outdoors for five months, undergoing a process of self-reflexive cycle: “reflecting and planning”, “acting and observing”, and “analyzing and reflecting”. Transcripts of debates and of students’ and teachers’ texts were subject to content analysis. This study on a topic of health education demonstrated that the Situation of Study implemented in a co-creation process was very efficient for students to develop significant learning.

title: SCHOOL COMPLAINT AND GENDER: THE (DES)CONSTRUCTION OF STEREOTYPES IN EDUCATION

description: ABSTRACT The prevalence of boys in school failure has been highlighted by several authors and the phenomenon has been added with the incidence of the diagnosis of ADHD in males. Based on data collected in an extension program for children with school complaints, this article aims to contribute to a theoretical-empirical articulation about the perpetuation of gender stereotypes in education. The method included the analysis of 142 registration cards, 172 observation protocols, and 10 conversation circles registers. In addition to the male predominance in the attendance, signs of sexist clichés were identified, especially the physical aggressiveness and impulsivity for the boys, and the cult of beauty for the girls. The research emphasizes the role of educators in the perpetuation of gender stereotypes and the fertility of conversation circles as instruments for their identification and deconstruction.

title: COVID-19: Economic Consequences for a Small Tourism Dependent Economy

description: Abstract This paper analyzes the economic impact of the COVID-19 pandemic on a small tourism dependent open economy. The lockdown affected both the demand side and the supply side of the economy, as production of goods and services dramatically dropped due to firms’ shutdowns, broken supply chains, or bankruptcies, and aggregate demand diminished due to lower consumer confidence and investment cutbacks, accompanied by a dramatic fall in international tourism demand, in particular due to travel restrictions. We look on these supply and demand changes through the lens of a macroeconomic model of a small open economy, comprising an industrial and a tourism sector. For this purpose, we modify Schubert’s (2013) model by introducing a multiple shock which reflects (i) reduced sectoral productivities due to, e.g., broken supply chains, (ii) a drop in employment due to firms’ lockdowns, and (iii) a sharp decline in international tourism demand. We find that the multiple shock leads to an immediate drop in GDP and a boost of the short-run unemployment rate, followed by a gradual transition back to steady state. The adverse effects on the tourism sector are the more severe the slower international tourism demand reverts to pre-crisis levels, but they do not strongly spill over to the industrial sector. Furthermore, even if international tourism demand recovers quickly, the effects on the industrial sector barely change. The length of the industrial sector’s recovery basically depends on the speed of restoring its sectoral productivity rather than on international tourism demand. The reason for this result can be found in the absorbing effect of the relative price of tourism services in terms of the industrial good.

title: Taxonomic and phylogenetic beta diversity in headwater stream fish communities of the Paraná and Paraguai River basins

description: ABSTRACT Patterns of species replacement and richness differences along environmental gradients or ecoregions shed light on different ecological and evolutionary mechanisms acting on community structure. Communities of aquatic ecosystems of different watersheds are supposed to host distinct species and lineages. Quantifying and understanding the degree to which these differences are affected by environmental and biogeographical factors remains an open question for these environments, particularly in the Neotropical region. We investigated patterns of taxonomic and phylogenetic composition of headwater streams of the Paraná and Paraguai River basins to understand how local and biogeographical factors affect the assembly of fish communities. We also quantified taxonomic and phylogenetic beta diversity by decomposing them into nestedness and turnover components. We found that local environmental factors are the main factors influencing the composition of stream fish communities. Whereas pH affected both taxonomic and phylogenetic turnover, water velocity was responsible for phylogenetic turnover and pH was the main driver of phylogenetic nestedness. Our results indicate an effect of local environmental factors in determining the structure of headwater stream fish communities through a combination of a species sorting mechanism (water velocity and pH) and phylogenetic habitat filtering (pH).

title: ELECTROLYTIC AND FUEL CELLS MADE WITH ALTERNATIVE MATERIALS FOR THE TEACHING OF ELECTROCHEMISTRY

description: The proposal addresses the electrochemical experimentation as a pedagogical instrument for the integral and dynamic student involvement, facilitating the teaching-learning process. The experimental proposal focuses on the conversion of electrical energy to chemical energy and vice versa. The experiments for the two simultaneous energy conversions were designed with simple, easily accessible and inexpensive reagents and materials. The production of hydrogen and oxygen gases in the electrolytic cell, and the consumption of these same gases in the fuel cell, exploits the non-spontaneous and spontaneous electrochemical semi-reactions, respectively, that occur at the anode and cathode. Hydrogen gas production is crucial to the development of fuel cell technology. To facilitate the identification of anodic and cathodic reaction, and the monitoring of electrochemical decomposition of water, black bean extract was used as an alternative indicator. The electrochemical reactions involved in energy conversions are considered fundamental in the teaching-learning process of basic concepts related to water electrolysis and the recombination of hydrogen and oxygen gases. The experiment also corroborates the elucidation of alternative ways to generate electricity to meet the current needs of modern society.

title: So alike yet so different. Differential expression of the long non-coding RNAs NORAD and HCG11 in breast cancer subtypes

description: Abstract Breast cancer (BC) is a heterogeneous disease, and it is the leading cause of death among women. NORAD and HCG11 are highly similar lncRNAs that present binding sites for PUMILIO proteins. PUMILIO acts on hundreds of mRNA targets, contributing to the modulation of gene expression. We analyzed the expression levels of NORAD and HCG11 in the BC subtypes luminal A (LA) and basal-like (BL), and the regulatory networks associated with these lncRNAs. In the analysis of TCGA cohort (n=329) and Brazilian BC samples (n=44), NORAD was up-regulated in LA while HCG11 was up-regulated in BL subtype. An increased expression of NORAD is associated with reduced disease-free survival in basal-like patients (p = 0.002), which suggests that its prognostic value could be different in specific subtypes. The biological pathways observed for the HCG11 network are linked to the epithelial-to-mesenchymal transition; while NORAD associated pathways appear to be related to luminal epithelial cell transformation. NORAD and HCG11 regulons respectively present 36% and 21.5% of PUMILIO targets, which suggests that these lncRNAs act as a decoy for PUMILIO. These lncRNAs seem to work as players in the differentiation process that drives breast cells to acquire distinct phenotypes related to a specific BC subtype.
