Five semi-continuous culture fermenters were used to test three dilution rates of the liquid phase (3, 5, and 7 %/h) in an incomplete 3 × 3 Latin square design. Three 10-day assays were performed, each consisting of a 5-day adaptation and stabilization period followed by 5 days of sampling. Each fermenter received 10 g of a total mixed ration, and artificial saliva was continuously infused, at the different experimental rates. The liquid effluent was measured and sampled daily for further analysis. Increasing the dilution rate did not affect N degradability or ammonia-N outflow, but linearly increased the outflow of small peptides and decreased the outflow of amino acids (p < 0.05). The sum of free amino acids and small peptides flowing out of the fermenter represented 21 to 54% of the N that disappeared from bags. The outflow of small peptides from fermentation vessels was directly impacted by increased dilution rate of the incubation medium, indicating that they may contribute significantly to the rumen undegradable protein fraction of feedstuffs.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"98 suppl 1","pages":"e20250566"},"PeriodicalIF":1.2,"publicationDate":"2026-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148787331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite their ecological, economic, and cultural relevance, scientific research on native species within this group remains limited. This study aims to analyse the scientific literature addressing native Bambuseae species recorded in Santa Catarina, identifying research trends, knowledge gaps, and priority areas for future inquiry. A bibliometric survey was conducted using SciVerse Scopus, ScienceDirect, Web of Science, SciELO, and PubMed, employing scientific names and synonyms of the target species as search terms. All articles referencing native bamboos from Santa Catarina as primary descriptors and published up to October 2023 were considered. The review encompassed 110 articles published across 78 journals. The number of publications increased markedly from the 2000s onwards, with a predominance of ecological research. Nonetheless, gaps remain, particularly concerning undomesticated taxa and topics such as ethnobotany and applied uses. Current research trends continue to favour ecological investigations, with growing interest in biochemical and nutritional studies. Ultimately, taxonomic, genetic, and propagation-related research is highlighted as essential for overcoming domestication challenges and advancing scientific progress in conservation and sustainable use. Such efforts may contribute meaningfully to biodiversity preservation and socio-economic development.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"98 suppl 1","pages":"e20250626"},"PeriodicalIF":1.2,"publicationDate":"2026-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148787297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the study was to evaluate the effect of the hydroalcoholic extract of R. pycnostachys fruit on the reproductive system of male Swiss mice. Twenty-one male Swiss mice were used, divided into 4 experimental groups. Control animals, sildenaﬁl citrate and 2 doses of the extract (50 and 150 mg/kg) were administered by gavage for 42 days, corresponding to the animal's reproductive cycle. Phytochemical screening identified the presence of flavonoids, tannins, triterpenes, and saponins, demonstrating a high free radical neutralization capacity. The extract did not cause any biometric, tubular, or intertubular changes, and consequently did not affect sperm production. It did not cause hormonal or oxidative status alterations. However, it did promote an increase in penile corpora cavernosa. These findings indicate that the extract increases the proportion of penile corpus cavernosum tissue without altering nitric oxide levels or serum testosterone. The molecular mechanisms underlying this effect were not investigated and remain to be elucidated.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"98 suppl 1","pages":"e20250818"},"PeriodicalIF":1.2,"publicationDate":"2026-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148787255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experimental groups were classified as follows: A. nyassae, Juvenile I-Any (1.29 ± 0.35 g) and Juvenile II-Any (2.97 ± 0.67 g); and A. stuartgranti, Juvenile I-Ast (1.98 ± 0.60 g) and Juvenile II-Ast (3.69 ± 0.74 g). For each group, 80 specimens were randomly allocated to seven eugenol concentrations (25, 50, 75, 100, 125, 150 and 175 mg L-1) and a control (ethanol) in a completely randomized design with 10 individuals per concentration. Anesthesia trials involved exposing one animal at a time to the different eugenol concentrations, and recording induction time, recovery time, but ventilatory frequency was also measured during induction and recovery. The efficacy of an anesthetic administered via immersion bath is related to rapid induction to deep anesthesia (<180 s) and short recovery (<300 s). Therefore, the study demonstrated that eugenol concentrations between 50 and 175 mg L-1 are recommended for Juvenile I-Any and between 25 and 175 mg L-1 for Juvenile II-Any. The ideal concentrations for A. stuartgranti, on the other hand, range from 25 to 175 mg L-1 for both evaluated size classes.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"98 3","pages":"e20251061"},"PeriodicalIF":1.2,"publicationDate":"2026-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148787428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, what are the conceptions and characteristics of interdisciplinarity in graduate programs within the Environmental Sciences evaluation area in Brazil? This study aimed to identify the epistemic trajectories of interdisciplinarity in graduate education within this field in the Brazilian context. To this end, interviews were conducted throughout 2024 and in early 2025 with 33 coordinators of graduate programs from different regions of Brazil. The results reveal distinct modes of interdisciplinary praxis, corresponding to varying levels of conceptual depth and application: Uncritical, Pragmatic-Problem-Solving, Systemic-Critical, and Libertarian-Emancipatory. These findings underscore that the evaluated graduate programs exhibit a diversity of interdisciplinary approaches and strategies, reflecting specific regional needs, institutional contexts, and epistemic trajectories. While interdisciplinarity was a common characteristic, its implementation and conceptual understanding varied significantly across programs.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"98 suppl 1","pages":"e20251258"},"PeriodicalIF":1.2,"publicationDate":"2026-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148719927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
