Concentration of selected biogenic and risk elements in liver, kidneys and muscle of domestic rabbit and wild brown hare. JOURNAL OF ENVIRONMENTAL SCIENCE AND HEALTH.

Abstract
In the present study the concentration of selected elements in tissues of domestic rabbits and of wild brown-hares (kidneys, liver, and muscle - m. quadriceps femoris) in Slovakian habitats were determined. After mineralization the elements examined were detected using flame atomic absorption spectrophotometry/graphite furnace atomic absorption spectrophotometry. For rabbits, Fe in the liver was correlated with essential (Mn, Cu) (R2 = 0.94, p < 0.05; R2 = 0.96, p < 0.05 respectively) or toxic (Pb) elements (R2 = -0.93, p < 0.05). For hares, significant correlations were found between Cd and Cu or between Cd and Mn in the kidneys (R2 = -0.96, p < 0.05; R2 = 0.92, p < 0.05 respectively), which is the target organ for Cd. Higher concentrations of the elements were found in hare tissue, and this may be linked to pollution of their wild habitats. The xenobiotic elements as well as the essential elements were accumulated in the kidneys of the hares than rabbits. For liver, differences were less pronounced and significance was only for Fe and Cu. Muscle of hares was more contaminated than of rabbits for both biogenic and toxic elements. These results show that detectable concentrations of inorganic elements. These levels may be linked to contamination of the natural habitats of wild biota due to industry, traffic, agriculture, and urban sprawl.

Effects of chronic low-level lead (Pb) exposure on cognitive function and hippocampal neuronal ferroptosis: An integrative approach using bioinformatics analysis, machine learning, and experimental validation. THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 917:170317.

Abstract
Lead (Pb), a pervasive and ancient toxic heavy metal, continues to pose significant neurological health risks, particularly in regions such as Southeast Asia. While previous research has primarily focused on the adverse effects of acute, high-level lead exposure on neurological systems, studies on the impacts of chronic, low-level exposure are less extensive, especially regarding the precise mechanisms linking ferroptosis - a novel type of neuron cell death - with cognitive impairment. This study aims to explore the potential effects of chronic low-level lead exposure on cognitive function and hippocampal neuronal ferroptosis. This research represents the first comprehensive investigation into the impact of chronic low-level lead exposure on hippocampal neuronal ferroptosis, spanning clinical settings, bioinformatic analyses, and experimental validation. Our findings reveal significant alterations in the expression of genes associated with iron metabolism and Nrf2-dependent ferroptosis following lead exposure, as evidenced by comparing gene expression in the peripheral blood of lead-acid battery workers and workers without lead exposure. Furthermore, our in vitro and in vivo experimental results strongly suggest that lead exposure may precipitate cognitive dysfunction and induce hippocampal neuronal ferroptosis. In conclusion, our study indicates that chronic low-level lead exposure may activate microglia, leading to the promotion of ferroptosis in hippocampal neurons.

Influence of age, habitat elevation, and distance to a thermal power plant on pathomorphological findings in the European brown hare ( Lepuseuropaeus P.). Vet Q 2023; 43:1-10. [PMID: 37869876 PMCID: PMC11003476 DOI: 10.1080/01652176.2023.2273887] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2023] [Accepted: 10/17/2023] [Indexed: 10/24/2023] Open
Abstract
The lifespan of the European hare (Lepus europaeus P.) is affected by a number of negative factors, including pollutants. In this paper, the individual and joint influence of age and habitat (elevation and distance from the thermal power plant - TPP) on pathomorphological findings of hares shot during three hunting seasons was investigated. Pathomorphological changes were found in 95.12% of hares. In hares up to 1 year of age, the changes were predominant in the lungs, and in older hares, in the kidneys. Degenerative changes in kidneys and liver and inflammatory changes in kidneys and lungs were considered important most in discussing the influence of chemical pollution. The proximity of TPP influenced the type of changes in the liver. A significant joint effect of age and elevation on the type of changes in the lungs of adult hares and on the heart of young hares was found. Elevation and distance from TPP had a joint effect on the occurrence of changes in the lungs, intestines, and heart in hares from the field farther from TPP. The results indicate that the hares were highly exposed to chemical pollutants that may affect their immunity, and lifespan.
