Subchronic Exposure to Arsenic and Nickel Triggers Nitrosative Stress and Histological Alterations in the Rat Liver

Journal of Applied Toxicology, EarlyView.
ABSTRACT Environmental exposure to heavy metals poses a threat to human health. Several studies documented harmful effects on the liver after arsenic and nickel exposure at concentrations beyond permissible limits. Nevertheless, the impact of a simultaneous exposure to both elements on hepatic biochemistry and histology remains unelucidated. Therefore,

Formulation‐Dependent Cytotoxic Effects of Commercial and Analytical‐Grade Mancozeb in C6 Glial Cells

Journal of Applied Toxicology, EarlyView.
ABSTRACT Mancozeb (MZ) is a widely used dithiocarbamate fungicide composed of manganese (Mn) and zinc (Zn) complexes. Increasing concern has been raised regarding its occupational and human health relevance, particularly due to its neurotoxic potential associated with Mn‐related cellular dysfunction.

Analysis of Gene Expression in Aedes aegypti Suggests Changes in Early Genetic Control of Mosquito Development

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
ABSTRACT Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for studying its embryogenesis due to difficulties in removing its rigid chorion and achieving effective fixation for in situ hybridization. Here, we present novel methodologies for fixation, dechorionation, DAPI staining, and in situ hybridization, enabling ...

Biofertilization of canola seeds with Peribacillus simplex and Paenibacillus polymyxa bacteria increases tocopherol content

JSFA reports, EarlyView.
Abstract Background Biofertilization with plant growth‐promoting bacteria (PGPB) is a reliable strategy to reduce the amounts of chemical fertilizers applied to crops. Nevertheless, the effects of biofertilizers on plant chemical constituents that influence food quality and human health should be evaluated.

DNA barcoding for identification of species involved in wildlife strikes at Brazilian airports

The Journal of Wildlife Management, EarlyView.
A collaborative network of 42 Brazilian airports applied DNA barcoding to identify 80 species involved in wildlife strikes. Among them, 32 species (17 birds and 15 bats) were not currently available in Brazil's wildlife strike reporting database, underscoring the value of molecular tools for strengthening wildlife strike monitoring. Abstract This study

Exometabolomics Reveals Metabolic Modulation Induced by Chia Oil Supplementation in Adipose Tissue Explants From Obese Mice

Lipids, EarlyView.
The experimental design and the exometabolomic findings obtained by 1H‐NMR analysis of conditioned media from subcutaneous (SAT) and epididymal adipose tissue (EAT) explants of control and obese mice supplemented with chia oil (1.5% (w/w)). Following 8 weeks of control or high‐fat diet and 5 weeks of chia oil supplementation, SAT and EAT explants were ...

Uncertainty in aquatic greenhouse gas flux estimates arises from subjective processing of floating chamber time series

Limnology and Oceanography: Methods, EarlyView.
Abstract Accurate quantification of greenhouse gas (GHG) fluxes from aquatic systems is essential for constraining regional and global carbon budgets. Closed floating chambers are widely used to measure carbon dioxide (CO2) and methane (CH4) fluxes at the water–air interface, yet large uncertainties persist due to subjective processing of chamber time ...

A simple index for assessing cumulative human impacts on mountain lakes

Limnology and Oceanography: Methods, EarlyView.
Abstract Mountain lakes are highly sensitive ecosystems and effective sentinels of environmental change, yet the exposure and magnitude of the human footprint remain poorly quantified. In this study, we develop a simple and non‐invasive abiotic index to assess cumulative pressures on mountain lakes. The proposed index integrates eight variables grouped
