title: Depicting latent variables considering different pig genetics and nutritional plans in crossbred pigs

description: ABSTRACT We aimed to reduce the dimensionality of quantitative traits in pigs applying factor analysis. Quantitative variables were collected, and the factor analysis extracted five factors with biological meaning related to performance, carcass quality, carcass yield, meat quality, and initial pH. These factors were posteriorly used as dependent variable to evaluate the effects of genetic groups (Piau, Duroc, and Pietrain crossbreds), nutritional plans (low, medium and high lysine levels) and sex. An interaction effect between genetic group and sex was observed in performance, in which Duroc crossbred showed the greatest scores. The Pietrain genetic group showed greater values of carcass quality compared with Duroc and Piau, while Piau crossbred pigs had greater values for meat quality compared with Pietrain and Duroc. A greater carcass yield was observed in Pietrain crossbred compared with Duroc pigs. Pigs fed under low lysine level had the lowest performance values. Carcass yield was affected by nutritional plans, in which the medium lysine level showed the greatest values. Meat quality was improved by the nutritional plan with high lysine level compared with the low lysine level. Initial pH showed increased means when using nutritional plans with low and medium lysine levels in diet composition. With regard to sex effects, a greater carcass quality was found for gilts compared with barrows. The reduction of the data dimensionality allowed the joint evaluation of genetic group, nutritional plan, and sex based on new latent variables that represented the original dataset under easier framework based on factors’ biological interpretation.

title: Improvement effect of enzymic polypeptide from Paeonia ostii seed meal on protein-energy malnutrition mouse model

description: Abstract The improvement effects of enzymatic polypeptide of Paeonia ostii seed meal (APHP) on model mice of protein-energy malnutrition were evaluated by body weight changes, organ indices, levels of SOD, CAT, MDA, total protein and albumin in serum, staining images of major organs and macrophages phagocytosis. The results indicated the mice body weight recovery was dose-dependent with APHP and the body weight change of model mice fed with high-dose APHP (5.0 g/kg) and normal diet showed a same recovery effect. The model mice had higher thymus and spleen indexes than other groups. And the values of SOD, CAT, MDA, total protein and albumin in serum returned to normal level after 30, 60, 45, 30 and 45 days respectively, which was better than those of normal diet. Our research will provide basic data support for new potential applications of APHP and increase the added value of Paeonia ostii processing enterprises.

title: Dysautonomia Evaluation by Holter in Chagas Heart Disease

description: Abstract Background Sudden cardiac death is the main lethal mechanism associated with Chagas cardiomyopathy. Studies suggest that dysautonomia may represent a relevant, intense, independent, and early phenomenon in the natural history of the disease, even when ventricular systolic function is preserved, and may also be the mechanism that triggers malignant ventricular arrhythmias. Objective To evaluate the degree of dysautonomia and its possible association with ventricular arrhythmias in patients with Chagas cardiomyopathy, according to different categories of mortality risk, as defined by the score proposed by Rassi, used as a surrogate outcome for death. Methods A cross-sectional study involving 43 patients with Chagas cardiomyopathy stratified into risk categories based on the Rassi score, with 23 being classified as low risk and 20 as intermediate-to-high risk. Heart rate variability (HRV) was assessed using Holter monitoring for long-term recordings of 24 hours (time domain) and for short-term recordings of 5 minutes (frequency domain) at rest and after autonomic tests: deep breathing and Valsalva maneuver. The HRV variables were compared between the groups using the Student's t-test and α=0.05. Results Comparison of the results between the risk stratification groups showed no differences in HRV indexes, either in the time or frequency domain. However, results showed a significant increase in the number of arrhythmias as a function of increased risk (p=0.02). Conclusion There was no association between the degree of dysautonomia, evaluated by Holter monitoring, and the categories of mortality risk, despite a direct association between the rate of arrhythmias and the higher risk group.

title: Immigration museums: new museographies, old paradigms

description: ABSTRACT As memorial institutions, museums play a big role in identity construction, with representations of the past and the cultural heritage being essential to developing national/regional identities. Transforming old representative facilities of immigrants - such as Ellis Island in New York - into “memory sites” shows a certain transformation in attitudes towards immigration, which has changed the status of “diaspora” and evidenced cultural identities. Due to the recognition of the heritage value of the memories, new discourses about immigration and identity were created: the memories, often forgotten - many times voluntarily -, find their place in museums and allow the construction of narratives about immigration from personal accounts. However, exhibiting immigration history continues to be a challenge within international museum spaces, raising various questions: What is immigration heritage? How to exhibit immigration? Do attempts at representing immigrants in these spaces mirror a national paradigm? Immigration museums represent a variant of the society museum by the participatory approach and the initiative to create a link with communities of immigrant origin. By constituting a local heritage on immigration, the museum has developed an approach with immigrant communities, highlighting its memorial and inclusive character. It is an interdisciplinary approach, which is favored by the best museums and suitable for new spaces intending on approaching the theme. In this article, we aim to consider the constitutive characteristics of immigration museums and the importance of oral history (personal accounts of immigrants), memorabilia, and contemporary art in developing exhibitions that plan to create a certain form of empathy in the visitor.

title: PERFORMANCE OF Calendula officinalis L. IN SUBSTRATES DEVELOPED WITH SOLARIZED SEWAGE SLUDGE AND AGRO-INDUSTRIAL WASTES

description: ABSTRACT Efficient products can be developed for the ornamental plant sector using agro-industrial waste. This study evaluated the agronomic performance and ornamental quality of calendula plants (Calendula officinalis) cultivated in substrates formulated with solarized aerobic sewage sludge (SASS), rice husk ash (RHA), and sugarcane bagasse (SB). Five additive rates were used: S2: 33.33% SASS + 33.33% RHA + 33.33% SB; S3: 16.65% SASS + 41.67% RHA + 41.67% SB; S4: 12.48% SASS + 43.76% RHA + 43.76 % SB; S5: 8.32% SASS + 45.84% RHA + 45.84 % SB; S6: 4.16% SASS + 41.07% RHA + 54.76% SB; and S1: commercial substrate (reference). Raw materials and substrate formulations were characterized and agronomic and ornamental aspects were evaluated in calendula plants cropped in all substrates. The lowest agronomic performance was observed in S6 (lowest SASS rate), while the highest occurred in S3 compared to the other treatments. Regarding the ornamental potential, S3 and S4 and the commercial substrate (S1) were classified as excellent. This study highlights the successful use of organic raw materials (SASS and agro-industrial waste) to compose substrates for calendula production in pots, with the recommended proportions ranging from 12.48 to 16.65% of SASS combined with RHA and SB.

title: Phenology of hass avocado in the Andean tropics of Caldas, Colombia

description: Abstract The objective of this study was to document and analyze the effect of climate on the phenological development of ‘Hass’ avocado in two contrasting zones of the Andean tropics of Caldas, located at altitudes of 1,950m and 2,400m a.s.l., respectively. A completely randomized experimental design was carried out using a five to seven year-old ‘Hass’ tree as experimental unit and 15 replicates on each area. Observations were conducted on lateral sylleptic shoots and their corresponding apical buds located on the eastern and western sides of each tree. The destination of the apical bud of lateral shoots was quantified, floral phenology was documented, heat units were calculated from reproductive bud stage 1 to anthesis and to harvest and root growth was followed for each study area. Air temperature, soil temperature, precipitation and photosynthetically active radiation (PAR) values were recorded over time. Differences were found in the number of apical buds of lateral shoots with reproductive and vegetative destination, flowering phenology, heat units, root growth, PAR and precipitation. Differences were found among variables evaluated at the two contrasting altitudes. There is a clear need for further ecophysiological studies on this fruit tree in tropical areas in particular.

title: University in dispute: echoes of Aparício Cora de Almeida’s itineraries in the present time (Porto Alegre - RS)

description: ABSTRACT This article discusses the life and death of Aparício Cora de Almeida and the repercussions of this biographical trajectory in the educational field, especially with regard to democratization of access to higher education in Rio Grande do Sul. The analyzes have as central axis the production of memories and forgetfulness around the image of this personage. A prominent student leader in the early 1930s, he was connected to movements aligned with the ideals of Córdoba (1918), which then disputed the university model that would be implemented in the state. He was also secretary of the National Liberating Alliance (ANL) in the state and a militant of the Brazilian Communist Party (PCB). In a context of strong repression of political movements opposed to Flores da Cunha’s government, with arrests and suspicions of assassinations of various opponents, the death of Aparício in 1935 is surrounded by cloudy circumstances, and his biography is intertwined with the history of the Rio Grande do Sul student movement. In honor of the son’s memory, the Family donated a building that would be the first University Housing of Rio Grande do Sul, and later would be called University Housing Aparício Cora de Almeida (CEUACA). This donation was of fundamental importance to the Academic Federation of Porto Alegre (FEUPA), which would operate in the same building, offering a broad structure of student assistance, unprecedented in the state.

title: Video-article publication as strategy to enhance science consumption

description: Abstract New technologies have promoted important changes in the social relations in recent years, stimulating the growth of scientific content production in audiovisual format, especially of video-articles. This article examines the applicability of the new trends of audiovisual publications as a strategy to enhance science consumption inside as well as outside the academic ecosystem. An exploratory-descriptive survey was performed with Brazilian researchers from the Health Sciences and Human Sciences areas, focusing on mitigating the lack of empirical evidence, regarding four points: their view of science consumption in Brazil; the lack of knowledge on the video-articles like scientific communication; the level of interest in scientific publications in audiovisual format; and feelings about the visibility and recognition of science in Brazil. Results reinforce the interest in audiovisual resource usage in scientific communication valorization, given that the researchers are interested in video-articles publishing for improving visibility, altmetrics, and expanding the dissemination of scientific culture, focusing to enhance science consumption.
