In these hilly areas, where basic facilities are lacking, residents primarily depend on local plants to treat various veterinary health issues. The aim of our research is to chronicle, explore, and quantitatively assess ethnoveterinary knowledge. The current study documents the use of ethnoveterinary plant medicine for curing different animal ailments. The majority of animal diseases are treated with local herbal medicines extracted from plants. To identify traditional remedies, the survey and information were collected from locals and farmers. Ethnoveterinary information was obtained through semi-structured interviews with 133 informants who were randomly selected from 17 villages, and the data were interpreted using various ethnobotanical indices. Altogether, 41 livestock ailments were documented, and it was concluded that ailments like digestive disorders, mouth and foot diseases, milk deficiency, diarrhea, worm infestation, skin disorders, wound healing, placenta retention, carminatives, and anti-lice are the most prevalent. Eighty-three plants from 36 families, including one species of pteridophyte and gymnosperm and 81 species of angiosperm, were identified for animal health care. Most frequently, plant parts used for ethnoveterinary medicine are leaves (56.8%), shoots (15.9%), fruit (8.87%), seed (8.87%), bark (2.95%), whole plant (2.95%), latex (1.77%), and root (1%). The most common administration is oral, followed by dermal. The inhabitants use leaves, fruits, seeds, shoots, and bark to prepare various oral and topical remedies. The plant species ranked highest in terms of RFC values were Mentha longifolia (0.76), Ajuga bracteosa (0.64), Carthamus oxyacantha (0.53), Brassica campestris (0.46), and Sonchus asper (0.42). Species with the highest use values include Ajuga bracteosa (1.03), Mentha longifolia (0.85), Brassica campestris (0.71), Carthamus oxycantha (0.54), and Sonchus asper (0.51). A high ICF was noted for digestive disorders (0.45), followed by lactation issues (0.41) and dermatological conditions (0.29). Given the enormous potential for popularizing local herbal remedies in the study area, this research underlines the critical need for further investigations to ensure a sustainable and safe utilization of these herbal drugs.</p>","PeriodicalId":55326,"journal":{"name":"Brazilian Journal of Biology","volume":"84 ","pages":"e288892"},"PeriodicalIF":0.0,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143191376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a deep sea fish distributed up to 2500 m and reaching up to 200 kg, 2 m total length and over 50 years of lifespan. Although it is of commercial interest, with prices between 14-35 US$/kg, studies that allow its cultivation are scarce. D. eleginoides is considered to have a slow metabolism since it lives at low temperatures (2-11 °C) and high pressures (100-250 atmospheres). However, there are no records of their routine aerobic metabolism (or any in fact) and of their mass scaling in tanks captivity on the surface, being the aims of this study. Routine metabolism was measured in fish groups from 3 sizes, a) 2.31 ± 0.08 kg, b) 4.67 ± 0.06 kg and c) 8.97 ± 1.89 kg in two respirometry chambers allowing to perform closed respirometry. The average metabolic rate was 42.91 ± 0.48, 38.61 ± 2.64 and 35.35 ± 1.58 mg O2 kg-1 h-1 along fish sizes, with significant differences between sizes. The calculated scaling exponent was 0.85, similar to that reported for other cold-water fish species measured at the surface. Results show oxygen consumption rates, under surface pressure conditions, comparable to those of G. morhua and salmonids, which allows, preliminarily, to reject the initial hypothesis of a slow metabolism. Although the results are preliminary, they are the first to report on the routine metabolism of this species, making them relevant for future studies.

Coville, commonly known as \"barbatimão,\" is native to the Cerrado biome in Brazil and belongs to the botanical family Fabaceae. The objective of this study was to evaluate the biological activity of crude hydroethanolic extracts formulated from the bark, leaves, and stems of S. adstringens. Soluble solids were determined using the incubation drying methodology. Colorimetric methods of complexation with ferric chloride were employed as a qualitative assay to identify the presence of tannins, while phenolics and flavonoids were quantified by the Folin-Ciocalteu method and aluminum chloride complexation, respectively. Antioxidant activity was assessed by the capture of DPPH free radicals. Antibacterial and antifungal analyses in vitro were conducted using the disk diffusion method against Escherichia coli, Mycobacterium tuberculosis, Pseudomonas aeruginosa, Staphylococcus aureus, Candida albicans, and Cryptococcus neoformans var. grubii. The MTT assay was used to determine antiparasitic activity against Leishmania amazonensis and to assess cytotoxicity using differentiated THP-1 macrophages. The extracts demonstrated efficacy against yeasts, especially the stem extract against C. albicans (7.62 mm), and against bacteria, with emphasis on the stem and leaf extracts against M. tuberculosis (both 9 mm). All extracts exhibited high antioxidant capacity, particularly the leaf and stem extracts (both over 92%) and low cytotoxicity (Cytotoxic Concentration - CC50 > 300 µg/mL). No extract was effective against L. amazonensis (Inhibitory Concentration - IC50 > 100 µg/mL). In conclusion, S. adstringens is a potential source of compounds with antibacterial properties (particularly against Gram-positive bacteria) and antifungal activity, with low cytotoxicity and high antioxidant activity.

The objective of this study was to evaluate the potential cytotoxic, genotoxic, and mutagenic effects of both free and encapsulated naringenin through in vivo experiments using Allium cepa L. roots, along with pharmacokinetic and molecular docking analyses. The results showed that naringenin nanoparticles did not produce significant changes in the cell division index of meristematic cells in A. cepa roots. Additionally, no significant alterations in the mitotic spindle or chromosomal breaks were observed. Molecular docking studies indicated that naringenin effectively binds to the active site of the catalase enzyme (CAT) in a competitive manner, while it attaches to a site away from the active site of superoxide dismutase (SOD2), demonstrating a non-competitive interaction. ADMET property assessments suggested that naringenin exhibits relatively low toxicity and has favorable molecular characteristics for oral administration.
