Serological and molecular evaluation of Senecavirus A (SVA) in pigs from farrow-to-finish farms in Minas Gerais, BrazilNARA Subscribed
The emergence of Senecavirus A (SVA) as a causative agent of vesicular diseases in pigs is noteworthy, since it was identified in 2014 through outbreaks in Brazil. The SVA belongs to the Picornaviridae family and is a non-enveloped virus with the ability to adapt to the environment. As the virus’s stability allows it to persist on farms post-outbreak, maintaining stringent biosecurity measures is crucial for effective control....
Canine cutaneous mast cell tumor (cMCT) is one of the most common skin neoplasms in dogs, with lymph nodes representing the primary route of metastasis. Accurate sentinel lymph node (SLN) identification is therefore essential for staging and treatment planning. This study evaluated indirect lipiodol lymphography (IL) and intraoperative methylene blue (MB) mapping in 21 dogs, including 26 tumors and 38 excised lymph nodes, to a...
Sheep breed-specific response to environment challenge against Haemonchus contortus and effect on immuno-hematological parametersNARA Subscribed
Variable resistance to Haemonchus contortus infection and the associated immune mechanisms have been investigated and characterized in different sheep breeds adapted to tropical climates. In a recent study, we compared the local immune responses of the resistant Santa Inês with those of the susceptible White Dorper and Texel sheep breeds under chronic haemonchosis, and evaluated the correlations of immune-related transcripts a...
Potential of Composted Macrophytes as a Sustainable Organic Fertilizer: Environmental and Agronomic InsightsNARA Subscribed
This study evaluated the agronomic potential and environmental impact of a macrophyte-based fertilizer (OMF) in maize cultivation. OMF was previously characterized in accordance with regulatory standards and applied to sandy loam and clayey soils at six rates (0, 2, 4, 6, 8, and 10 g dm⁻³). The experimental design also included a mineral fertilizer (MF) control receiving N, P, and K amounts equivalent to the 10 g dm⁻³ applicat...
Rhizosphere organic acids drive nutrient release from silicate rock powders across contrasting tropical soilsNARA Subscribed
Aims Silicate rock powders can enhance nutrient availability through rhizosphere-mediated mineral weathering. Although organic acids mediate this process, how soil fertility shapes their interactions with rhizosphere microbial communities and nutrient release remains poorly understood. He, we evaluated how contrasting soil fertility influences rhizosphere organic acids, microbial communities, and nutrient release from silicate...
Euterpe edulis Martius (juçara palm) is an endangered species of high ecological and economic importance. Its propagation via reproduction is limited by the recalcitrance of its seeds, which hinders conservation and genetic improvement. Somatic embryogenesis represents an efficient alternative for large-scale clonal propagation and conservation. The present study evaluated the effect of abscisic acid (ABA) on histodifferentiat...
Metal contamination, particularly by copper (Cu) and lead (Pb), is a persistent environmental threat, yet the adaptive responses of Neotropical bryophytes to such stressors remain largely unexplored. This study evaluated biomass production, photosynthetic performance, and metal accumulation in two native Brazilian mosses ( Campylopus savannarum (Müll.Hal.) Mitt. and Polytrichum juniperinum Willd. ex Hedw.) exposed to increasin...
Euterpe edulis is of ecological and economic relevance and is currently threatened with extinction. Its vulnerability to extinction, combined with the recalcitrant nature of its seeds, justifies the search for alternative reproduction techniques. Somatic embryogenesis is an alternative propagation method that is subdivided into distinct phases. Maturation is a crucial phase in the process for the successful regeneration of som...
Sweet potato is a crop of high nutritional and functional value widely grown in tropical regions. This study aimed to characterize sweet potato farmer-named cultivars grown by local farmers in Bahia, Brazil, based on physicochemical and color traits, and to evaluate the agreement of farmer-based classifications using multivariate approaches. Twenty samples representing different cultivars, collected in the municipalities of Cr...
L -asparaginase is an amidohydrolase enzyme that catalyses the hydrolysis of L-asparagine into L-aspartic acid and ammonia. This enzyme has significant biotechnological applications, functioning as an antineoplastic agent in the pharmaceutical industry and as a tool for reducing acrylamide formation in the food industry. This study aimed to identify a filamentous fungus strain capable of synthesizing a new L -asparaginase and...
In forest tree populations, the timing of budbreak (TBB) depends on several factors, both environmental and genetic. The genomic architecture underlying this trait is still not fully characterized. So far, common garden experiments have highlighted a few genomic regions with little heritability, while the whole spectrum of TBB variation observed in the wild still remains unexplored. We performed an in situ genome‐wide associat...
Silica nanoparticles alter cadmium partitioning and physiological responses within the substrate–plant system of soybeanNARA Subscribed
Background and aims Cadmium (Cd) is a toxic and bioaccumulative element introduced into agricultural systems through phosphate fertilizers, anthropogenic inputs, and accidental contamination, thereby endangering crop productivity and food safety. Its high mobility in soil also raises concerns regarding environmental dispersal and ecological exposure. Silica nanoparticles (SiO₂ NPs) have been proposed as mitigators of metal-ind...
