Several bioceramics have been developed to promote bone repair. However, postoperative infections in the implanted area may led to in bone resorption. The widespread use of antimicrobials has contributed to the increased prevalence of multidrug-resistant bacteria, posing an additional challenge to therapeutics. This study aimed to evaluate the antimicrobial activity and resistance-inducing potential of two bioceramic formulati...

Intensive swine production stressors induce stress responses that compromise welfare and health, positioning behavior as a critical welfare indicator. Although antibiotics traditionally improve performance, antimicrobial resistance concerns have driven the search for alternatives. This systematic review evaluated the influence of zootechnical additives, used as alternatives to antibiotic growth promoters (AGP), on pig behavior...

Main conclusion In miRNA–mRNA regulatory modules of Setaria italica , the candidate novel miRNAs Sit-miR74-N/APX7 and Sit-miR132-N/PEPC involved in key pathways underlying water-deficit response have been detected. In the first module, APX7 expression was directly associated with water-deficit intensity, whereas in the second module, PEPC activation occurred under moderate water deficit. Abstract Drought severely constrains pl...

Optimizing maize–Brachiaria intercropping requires effective weed management with selective maize herbicides. This study evaluated the spray performance and efficacy of atrazine + nicosulfuron for weed management in maize–Brachiaria intercropping, focusing on how droplet classes and spray volumes affect maize growth and yield. The deposition experiment was conducted in a greenhouse in a completely randomized design with six re...

We report the first complete nucleotide sequence of an isolate of iris yellow spot virus (IYSV; Orthotospovirus iridimaculaflavi ) from Brazil. Isolate Br-25 was collected in 2025 in Imbuia, Santa Catarina, from symptomatic onion scapes. The genome of IYSV-Br-25 consisted of L, M and S genomic RNAs of 8879, 4866 and 3223 nt, respectively. Comparison of the L segment nucleotide (nt) sequence showed identities ~96% to most of th...

Plant-parasitic nematodes of the genus Meloidogyne , commonly known as root-knot nematodes, pose a significant threat to global agricultural productivity. Due to concerns about environmental impact and human health risks, the use of commercially available synthetic nematicides has become increasingly restricted. Consequently, the search for natural molecules with nematicidal properties has emerged as a promising alternative. I...

The aim of this study was to evaluate the effect of xylanase addition (1.8 g/kg dry matter [DM]) to tropical grass haylage used in total mixed rations (TMR) on in vitro organic matter degradability, ruminal fermentation kinetics, and methane (CH4) emission. A completely randomized design was adopted in a 4 × 2 factorial arrangement, corresponding to four tropical grass cultivars (Andropogon, Mombaça, Massai, and Marandu) with...

Aim We investigate the distribution of dispersal modes — endozoochory (via animal ingestion), synzoochory (via animal seed accumulation) and anemochory (via wind)—and seed mass of woody plants across Brazilian ecosystems, testing whether their relative abundance in local plant communities could be predicted by climate, edaphic factors and dispersal agents (e.g., the main vectors moving seeds). We expected climate to be the mai...

Cover crops have the potential to reduce agricultural inputs, but the long-term impacts of cover crops on soil chemical properties and nutrient cycling in tropical systems are not fully understood. This study evaluated the impact of different cover crop systems under long-term no-tillage on shoot dry mass (SDM) production, nutrient cycling, soil chemical properties, and soybean yield in succession in the Cerrado region of Mato...

The present study investigated the adaptive strategies of Africanized and Buckfast honey bee colonies in a dry tropical environment, considering the thermohygrometric dynamics of the colonies. The internal temperature (IT) and internal relative humidity (IRH) were continuously recorded 24 h a day for seven months, yielding 36,360 observations in ten Africanized colonies and 22,680 observations in eight Buckfast colonies for ea...

Small Ruminant Lentiviruses (SRLVs) are widespread retroviruses of goats and sheep with significant economic and health impacts on small ruminant production systems. This study aimed to investigate the prevalence and genotype distribution of SRLVs in dairy goat flocks from Brazil. A total of 433 blood samples from eight dairy goat farms were analyzed via PCR targeting the gag gene. The overall SRLV prevalence was 32.6%, with m...

Antineutrophil cytoplasmic antibody (ANCA)-associated pachymeningitis is a rare inflammatory disorder of the dura mater that may occur in isolation or as part of systemic vasculitis. The clinical features and outcomes of proteinase 3 (PR3)- and myeloperoxidase (MPO)-ANCA-associated pachymeningitis remain poorly defined. We aimed to synthesize clinical presentation, investigations, and treatment outcomes to improve diagnosis an...

Multiple drivers shape biodiversity loss worldwide. Land-use change and biological invasions are major direct pressures on species, while climate change increasingly alters species distributions and community dynamics, often intensifying other stressors. However, these factors are still insufficiently integrated into Ecological Niche Modeling (ENM) studies. We quantified the potentially suitable area for Schinopsis brasiliensi...

The Cerrado biome, spanning ~2 million km 2 , is one of the most extensive and biodiverse tropical savannas, yet it is paradoxically dominated by only 30 hyperdominant tree species (~2% of all species, > 50% of all stems). However, their vulnerability to climate change and the effectiveness of current conservation efforts remain uncertain. By combining (i) species distribution models calibrated with edaphic‐climatic predictors...
