Eimeria lata is a recently characterized species of domestic chicken whose sensitivity to anticoccidial drugs remains largely unknown. This study aimed to determine the anticoccidial sensitivity profile of the Brazilian E. lata BR-AMC isolate, obtained from alternative production systems, through an anticoccidial sensitivity test (AST). One hundred ninety-two broiler chicks were allocated into six treatment groups: unmedicated...

Anesthetics are widely employed in aquaculture and in research environments utilizing fish as experimental models, with the aim of mitigating stress and hypermotility during handling procedures. Among the most commonly used anesthetic agents, eugenol stands out for its suitability across multiple species, enabling safer handling and transportation while minimizing physiological impact on the animals. For the experimental proce...

Improper disposal of municipal solid waste is a major source of soil and groundwater contamination, posing risks to ecosystems and public health. In this context, continuous and low-impact monitoring techniques are essential for tracking contaminant plume evolution around landfill sites. This study aims to evaluate the temporal evolution of a leachate-contamination plume at the Bauru Municipal Landfill (São Paulo State, Brazil...

This study aimed to evaluate the effect of topical application of a mouth gel formulation containing iron tetracarboxyphthalocyanine (FeTcPc) during non-surgical periodontal treatment. Forty-seven individuals with periodontitis underwent a standard periodontal treatment (scaling and root planing), followed by adjuvant therapy according to the = groups: Vehicle Group ( n = 15), receiving local application of the FeTcPc gel vehi...

Water quality monitoring is essential for water resources management, especially when conducted systematically (continuous, standardized, and with data available to users), as it generates historical time series for each observed variable. The Amazon River basin plays a crucial role in biodiversity conservation and climate regulation, in addition to supporting a wide range of economic activities, making systematic monitoring e...

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...

The squirrelfish family (Holocentridae) represents a ubiquitous and ecologically vital component of coral reef fauna. Their vast oceanic distribution across oceanic barriers in some species presents a unique opportunity to investigate karyotypic evolution on a vast spatial dimension. Here we conducted the first interpopulational cytogenetic analysis of Myripristis jacobus and Holocentrus adscensionis (Atlantic Ocean), and Sarg...

Brain cancers hijack biological systems involved in neural development and synaptic plasticity. Medulloblastoma (MB), the most common malignant brain tumor in children, is thought to arise from disruptions in neurodevelopmental programs. Glutamatergic transmission mediated by α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors (AMPARs) has been implicated in synaptic communication between adult brain tumors a...

Biohydrogen production through dark fermentation (DF) is a promising process that attracts increasing attention in the context of energy transition. However, a deeper understanding is necessary to enable its upscale to industrial applications. This study investigated DF using three inocula sources - anaerobic UASB sludge (PS), activated sludge (AS), and cow manure (CM) – all subjected to acid (APT) and thermal pretreatments (T...

Human-induced environmental changes cause shifting baseline syndrome (SBS), where degraded conditions redefine ‘normal’, leading to generational differences in perception and ultimately influencing biodiversity conservation strategies. In this case study, we examine (1) whether forest degradation influences SBS through local ecological knowledge (LEK) of woody medicinal plants, and (2) whether the cultural transmission of LEK...

The enteric nervous system (ENS), a complex network of neurons and glial cells, is essential for maintaining intestinal homeostasis and is implicated in neurodegenerative diseases such as Parkinson's disease (PD). The gut-brain axis, modulated by gut microbiota (GM), is influenced by dietary compounds that can alter its composition. Despite advances in the understanding of PD pathophysiology, effective treatments remain limite...

Background and aims Drought limits maize ( Zea mays L.) productivity worldwide. Microorganisms from hypersaline habitats possess traits that may mitigate water deficit through osmotic stress adaptations. We aimed to evaluate isolates from these environments as bioinputs for maize and to resolve whether their effects act via resistance (maintenance under stress) and/or resilience (recovery after rehydration). Methods We tested...
