Ellagic acid (EA) is a plant-derived polyphenolic compound recognized for its therapeutic potential and favorable safety profile in the treatment of various diseases. This study aimed to evaluate the therapeutic effects of EA, formulated as novasomes (NOV), against IMI-induced thyroid dysfunction and to investigate the underlying mechanisms. Rats were divided into four equal groups: control, EA-NOV, IMI, and IMI + EA-NOV. Thyroid function was assessed by measuring free triiodothyronine (T3), free thyroxine (T4), and thyroid-stimulating hormone (TSH) levels. Thyroid tissues were examined to evaluate histopathological alterations, as well as to assess the oxidative/antioxidant pathway (Nrf2, SOD, TAC, MDA), inflammatory pathway (IL-1β, TNF-α, NF-κB), apoptotic pathway (<i>Bcl</i>, <i>BAX</i>), and autophagy pathway (<i>PI3K/Akt/mTOR</i>, <i>P53</i>, <i>Beclin-1</i>). Exposure to IMI resulted in impaired thyroid function, the upregulated gene expression of the <i>PI3K/Akt/mTOR</i> pathway, and downregulated <i>P53</i> expression. Additionally, immunohistochemical staining revealed Beclin-1-mediated autophagy, alongside increased apoptosis, oxidative stress, and elevated levels of inflammatory cytokines. Conversely, EA improved thyroid function and ameliorated histopathological alterations by enhancing autophagy-inducing pathways. Additionally, the alleviation of oxidative stress was evidenced by the increased immunohistochemical staining of Nrf2, which promoted the synthesis and activity of antioxidant enzymes and reduced apoptotic and inflammatory markers.

Therefore, scientific risk thresholds and ecological risk assessment methods must be established for PAHs in petroleum-contaminated soils. (2) Methods: In this study, based on the environmental DNA (eDNA) method, the soil bacterial community was considered as a receptor to assess the ecological risks of PAH contamination in aged petroleum-polluted soils. A combination of the risk quotient and the equivalent toxicity factor was used to assess the ecological risk of PAHs. (3) Results: A dose-response curve was plotted to determine the 50% effective concentration (EC₅₀) of the total equivalent toxicity for 16 PAHs (∑TEQ_BaP) in petroleum-contaminated soils. Following the plot of the species sensitivity distribution (SSD) curve, the hazardous concentration for protecting 95% species values (HC₅) of petroleum hydrocarbons (TPHs), electrical conductivity (EC), and total equivalent toxicity of PAHs were calculated to be 892.1 μs·cm^-1, 149.9 mg·kg^-1, and 0.2601 mg·kg^-1, respectively. The regression models of the distribution factor (DF) and aging factor (AF) were defined as DF = -1.132 SOM + 0.033PAHs + 9.968 and AF = 242.518 SOM + 1256.029 lgpH + 0.024 EC - 1415.447. Following calibrations of the DF and AF, the value of HC₅ was determined as 0.1956 mg·kg^-1, which could be considered the risk threshold of the total toxicity of PAHs. The calibrated toxicity data distribution was consistent with that of the normal cumulative probability distribution model. The results showed that 50% of the aged petroleum-contaminated soils showed high-risk levels of bacterial communities exposed to PAHs.

Rats were injected with DEN to induce preneoplastic lesions, and then they were orally administered with 1 µm MPs 0.5 mg/kg body weight per day for 20 weeks. The results revealed that long-term exposure to MPs did not induce the formation of glutathione <i>S</i>-transferase placental form (GST-P)-positive foci as preneoplastic lesions during hepatocarcinogenesis in these animals, thereby indicating non-carcinogenicity. However, MP exposure resulted in a 1-fold increase in both the number and size of GST-P-positive foci in rats initiated with DEN compared to those treated with DEN alone. Accordingly, MP exposure led to a 0.61-fold increase in the index of proliferating cell nuclear antigen (PCNA)-positive cells in DEN-initiated rats when compared to DEN treatment alone. In addition, the composition of the gut microbiota was significantly altered, accompanied by various levels of short-chain fatty acids. Our results suggest that long-term MP exposure can promote pre-neoplastic lesion formation in DEN-induced rats by increased cell proliferation as well as alterations in the gut microbiota and short-chain fatty acid levels.

This review systematically examines two pivotal dimensions: (1) evolving regulatory frameworks governing antibiotic usage and (2) emerging non-antibiotic alternatives, with a particular focus on their implementation mechanisms and technological maturation. The analysis of transnational antibiotic governance encompasses comparative policy evolution in the European Union, the United States, and China. These regulatory paradigms address critical control points including registration management policies, usage monitoring systems, and integrated surveillance programs. Concerning technological alternatives, six categories of antibiotic substitutes are critically evaluated: Chinese herbal formulations, plant-derived essential oils, antimicrobial peptides, microecological agents, acidifiers, and enzyme preparations. These solutions are functionally categorized into prophylactic agents (enhancing disease resilience) and zootechnical additives (optimizing feed efficiency). These antibiotic alternatives demonstrate certain efficacy in alleviating the challenges of antibiotic overuse, yet they still face multiple implementation barriers. Further investigations are warranted to establish standardized efficacy evaluation protocols and conduct technoeconomic feasibility assessments under commercial-scale production conditions. Ultimately, resolving the antibiotic dilemma requires synergistic collaboration between regulatory bodies, pharmaceutical innovators, and academic researchers.

These findings suggest that HMX exerts toxic effects on PC12 cells, involved in oxidative stress, and disturbances in Ca²⁺ and BDNF, accompanied by aberrant iGluRs.
