The first experiment aimed to evaluate the effect of phosphatidylcholine administration in the rumen or abomasum on the digestibility of dry matter and nutrients, as well as ruminal and blood parameters of cattle. Five Jersey castrated male animals with an average body weight of 829.6 ± 34.6 kg, fitted with a ruminal cannula and distributed in a 5x5 Latin square, were used. Five treatments were evaluated, one without the addition of phosphatidylcholine (control) and the others consisting of combinations of doses of 3 or 6 g/100 kg of body weight of phosphatidylcholine with the site of administration, either the rumen or the abomasum. The intake and total digestibility of dry matter and nutrients were evaluated. In ruminal fluid, pH and N-NH3 were evaluated, and the concentrations of glucose, triglycerides, and cholesterol in the blood. There was no difference in dry matter and nutrient intake between treatments. No significant differences were observed in digestibility. There were no differences in ruminal parameters, pH and N-NH3. Plasma glucose concentration was higher when phosphatidylcholine was administered into the rumen compared with administration into the abomasum, while cholesterol concentration was lower. The second experiment aimed to evaluate the effect of mycotoxin adsorbent use on endotoxin control in cattle fed a high-starch diet. Four Jersey cattle (806 ± 45 kg) with ruminal cannulas were used in a 4 x 4 Latin square design. The treatments consisted of four adsorbent inclusion levels: 0 g/kg BW (control); 20 mg/kg body weight (BW); 40 mg/kg BW and 80 mg/kg BW. Each experimental period lasted 21 days, of which, in the first seventeen days, the steers were fed a maintenance diet consisting of a roughage:concentrate (R:C) ratio of 80:20 on a dry basis without the adsorbent. From the 18th to the 21st day, the animals received the adsorbent and a challenge diet with a R:C ratio of 30:70. Blood, ruminal fluid, and feces were collected for lipopolysaccharide (LPS) evaluation. The dietary change resulting in acidosis caused an increase in the endotoxin concentration in all samples evaluated. The use of the adsorbent showed a tendency to reduce the endotoxin concentration in ruminal fluid samples; however, it did not change the endotoxin concentration in plasma or feces.

The research addresses the insertion, organization, and provision of health services in the municipality before the creation of the SUS and in the initial years of its constitutionalization, seeking not only to revisit this historical path but also to identify the impasses and challenges faced, as well as to understand the perspectives of the different actors involved – managers, workers, service providers, and users. The analysis also considered social participation in health policy through the Municipal Health Council. To understand the object within the empirical reality, interviews were conducted, guiding data collection and raising new questions, allowing the study to be developed based on oral narratives. The accounts obtained reveal themselves as important records of social memory, expressing recollections about public health before, during, and after the implementation of the SUS (Unified Health System) in the municipality.

The author had a wide circulation of her texts and lectures throughout Latin America and Europe, and established contacts and intellectual affinities in these spaces, especially in Argentina, Uruguay, Spain, and France. In order to fulfil the objective of the work, we analysed Lacerda's intellectual formation based on her theoretical and political divergences. These divergences, added to the context faced by intellectual women in the early 20th century, help to explain the silence that lasted for years regarding her anti-fascist action and production. In addition to her prolific works in Brazil, Maria Lacerda de Moura was part of an international intellectual network. This network facilitated the dissemination of her works and allowed her to establish dialogues with other anarchist intellectuals, especially anarcho-individualists, which was the tendency that underpinned the author's thinking. This intellectual network was mainly supported by eclectic publications, such as the Spanish magazine Estudios (1928–1937) and the Argentine magazine Nervio (1931–1936), to which Lacerda made significant contributions. Estudios played a fundamental role in Lacerda's theoretical development, as its focus on neo-Malthusianism, sexual emancipation, eugenics, and psychoanalysis directly aligned with the author's interests. The theoretical perspective produced by the magazine's contributors reverberates Lacerda's intellectual output, undergoing a particular reworking by the writer. Based on the articulation of recurring perspectives in Latin American anti-fascism and debates specific to individualist anarchism, obtained from her international intellectual network, Maria Lacerda de Moura developed her interpretation of fascism with a focus on subjective and cultural aspects. Despite understanding the phenomenon as the result of a crisis in the industrial capitalist system, the author added to this reading a subjective view that advocated the psychological and moral formation of individuals to reflect on the reasons for the emergence of fascism and propose strategies that she considered effective for anti-fascist resistance. This perspective brings unique characteristics to Maria Lacerda de Moura's anti-fascist thinking, placing sexual emancipation – especially of women – and the inner, mental development of individuals to abandon ‘herd servility’ at the center of the anti-fascist debate. The inner “elevation” of individuals would make them masters of themselves, and only then would they be able to resist fascism and all forms of authoritarianism culturally rooted in patriarchal, capitalist and clerical oppression.

This study aimed to relate the structure of free-living nematode communities with the activity of microbial enzymes (β-glucosidase, acid phosphatase, and arylsulfatase) in a no-till organic system under seven different crop rotations, seeking to identify integrated indicators of soil quality. Twenty composite soil samples (0-10 cm) were collected in an experimental area. Nematodes were quantified and identified, ecological indices (diversity, maturity, trophic ratios) were calculated, and the activity of the three enzymes was determined. Data were subjected to descriptive statistics, correlation analysis, geostatistics (kriging), principal component analysis (PCA), and clustering. Results revealed high spatial variability in nematode abundance, with dominance of bacterivore groups (56.5%) and a decreasing gradient of diversity and maturity among plots. Enzymatic activities showed independent spatial patterns, with higher values associated with more diversified rotations. PCA and cluster analysis successfully integrated both datasets, identifying five distinct ecological profiles that combine specific nematode signatures with enzymatic activities. Kriging of the principal components allowed the spatial visualization of these patterns. In conclusion, the nematode community and enzymatic activity are sensitive and complementary bioindicators. Their integrated assessment provides a robust tool for diagnosing soil health and biological quality in sustainable agricultural systems, being strongly influenced by the diversification of crop rotations.
