Urban freshwater ecosystems are increasingly exposed to mixtures of pollutants, including per- and polyfluoroalkyl substances (PFAS). However, their ecological effects remain poorly understood, especially in tropical regions with limited sanitation infrastructure. This study investigated PFAS contamination, water quality, and microbial community structure in Pampulha Lake, a tropical urban reservoir in southeastern Brazil. Spa...
Short-term depuration reduces the levels of microplastics of a commercial mussel from Eastern AmazonNARA Subscribed
Consumption of contaminated shellfish can be a pathway of human exposure to microplastics (MPs). Depuration is a treatment step that can effectively reduce the particle content of bivalves; however, this technique is not yet employed for mussels sold in the Eastern Amazon coast, in Brazil. Hence, this study aimed to verify the efficacy of 24 h, 48 h, and 72 h depurations in reducing the MP concentrations of the native mussel M...
Welfare and Physiological Consequences of Non‐Lethal Blood Sampling From the Caudal Vasculature of Atlantic Salmon ( Salmo salar L.)NARA Subscribed
The objective of this study was to evaluate welfare and health effects following single and repeated non‐lethal blood sampling from the caudal vasculature of Atlantic salmon. Two experiments were conducted at three different temperatures: a 6‐week freshwater experiment with fish weighing 50–100 g, undergoing up to four blood withdrawals, and a 4‐week seawater experiment with fish weighing 300–450 g, undergoing up to three bloo...
Effects of Sulphate‐Reducing Bacteria Mixed‐Species Biofilms on Microbiologically Influenced CorrosionNARA Subscribed
Sulphate reducing prokaryotes are widely acknowledged as key contributors to microbiologically influenced corrosion in industry. Characterisation of their behaviour within mixed‐species biofilms that reflect ecologically relevant conditions is limited. A novel dual anaerobic biofilm reactor protocol allowed a complex microbial consortium to be investigated. Continual biofilm growth resulted in significantly greater corrosive p...
Microclimate conditions in conservation spaces such as museums, galleries, storages, archives, and libraries significantly impact the preservation of cultural materials, potentially leading to permanent damage. This study focuses on quarantine rooms, essential for isolating and inspecting incoming collections for infestations or contamination. Despite their importance, systematic microclimate investigations in such spaces have...
Prostate cancer (PCa) is a highly heterogeneous and unpredictable progressive disease. Sensitivity of PCa cells to androgens play a central role in tumor aggressiveness but biomarkers with high sensitivity and specificity that follow the progression of the disease has not yet been verified. The vitamin D endocrine system and its receptors, the Vitamin D Receptor (VDR) and the Protein Disulfide-Isomerase A3 (PDIA3), are related...
