Influence of Age and Exposure Pathway on Copper and Cadmium Mixture Toxicity: A Study on Daphnia magna

Environmental Toxicology, EarlyView.
ABSTRACT Metal contamination in aquatic ecosystems poses substantial risks to freshwater organisms, with mixture effects often deviating from predictions based on single‐metal toxicity. Understanding how age‐specific sensitivities and multiple exposure pathways influence mixture effects is critical for accurate risk assessment.

Diagnosis of bovine genital leptospirosis in asymptomatic bulls: Comparison of methods and samples under field conditions

Veterinary Record, EarlyView.
Abstract Background Bovine leptospirosis is a zoonosis of global importance that is associated with reproductive losses. Although diagnosis in females has advanced, genital infection in males remains poorly understood. This cross‐sectional study aimed to compare diagnostic methods and sample types for detecting bovine genital leptospirosis (BGL) in ...
