Summary: The potential for trophic transfer of single-walled carbon nanotubes (SWCNTs) was studied using green algae and blue mussels. The researchers found that SWCNTs adhered to the external algal cell walls and were internalized. The growth of algae was significantly decreased after SWCNT exposure, and mussels showed evidence of SWCNT-containing algae in their digestive gland. Furthermore, DNA damage and oxidative stress biomarker responses in mussel tissues were altered, consistent with previous observations of SWCNT exposure. These findings suggest that SWCNTs can enter the food chain and may have implications for human exposure and health.

Summary: Heavy metal pollution has harmful consequences on soil fertility, and earthworms are used as test organisms to evaluate the ecotoxicity of polluted soils. This study exposed Eisenia andrei to polymetallic contaminated soils for 7 and 14 days in southeastern Tunisia. The results showed increased heavy metal accumulation, genotoxicity, and cytotoxicity in earthworms after 14 days of exposure, as well as changes in biochemical and transcriptional responses. These findings support the use of earthworms as bioindicator species for pollution monitoring and provide valuable information about the harmful impact of biota exposure to contaminated soils.

Summary: Research has shown the development of conceptual models linking anthropic stressors to aquatic environment changes, with the DPSIR structure at the core. This study introduced a general conceptual model incorporating technological disasters, applied to assess the Lower Doce River's state pre and post a specific iron-ore dam failure scenario. The model identified the combined effect of pre-existing pressures and those from the technological disaster, providing a holistic view of the problem.

Summary: The study aimed to investigate the potential of Pleurotus strains in removing toxic metals from the water of the Doce River. Results showed that the Pleurotus efficiently reduced lead, iron, aluminium, manganese, arsenic, and barium concentrations in the water samples, while also decreasing the mutagenicity of the samples. Studies on contact time effect revealed that peak metal elimination was achieved within 12 to 24 hours after fungal inoculation for most metals, indicating the biotechnological potential of these Pleurotus strains in bioremediation.

Summary: This study investigates the toxicity and cellular response to metal ions released by fixed orthodontic appliances on gastrointestinal tract cells. The eluates of archwires, brackets, ligatures, and bands were tested for their prooxidant effect, cytotoxicity, and genotoxicity on four different cell lines. The results show that most eluates were toxic to CAL 27 cells and that CaCo-2 cells were the most resistant. The eluates induced free radical formation in AGS and Hep-G2 cells, and eluates containing Cr, Mn, and Al showed slight prooxidant effect and genotoxicity.

Summary: In 18.43% of the 3721 TLE procedures, unexpected difficulties including lead venous blockage, lead dislodgement, and broken lead fragment occurred. These difficulties were mostly associated with long lead dwell time, younger patient age, lead burden, and poor procedure effectiveness. However, some problems seemed to be related to cardiac implantable electronic device (CIED) implantation and subsequent lead management strategy.

Summary: The use of standard single-extraction procedures to evaluate trace elements in soil or sediment analysis is common practice. However, these procedures might be misleading when applied to sediment analysis without further investigation. This study investigated the effect of incubation time on the efficiency of three standard single-extracting reagents (0.01 M CaCl2, 1 M NH4NO3, and 0.05 M EDTA). The results showed that longer incubation times yielded higher concentrations in sediments compared to soils for some elements.

Summary: The uncontrolled spread of multidrug-resistant pathogens is a major global health threat. Antimicrobial photodynamic therapy (aPDT) offers a promising approach to treating localized infections without being limited by drug resistance. In this study, various techniques were used to investigate the biochemical mechanisms of aPDT. The results suggest that protein degradation correlates with microbial inactivation kinetics, providing important insights for the development of optimized photosensitizing drugs and combination therapies with antimicrobial chemotherapy.

Summary: The study investigates the involvement of cellular prion protein (PrPC) in neuroprotection under oxidative stress. The presence of PrPC showed resistance to oxidative stress in astrocytes, and PrPC plays a role in metal homeostasis and prevents protein aggregation. Additionally, PrPC can translocate SOD1 to cell nuclei under oxidative stress, potentially controlling DNA damage. Overall, the study suggests that PrPC activates cellular response and defense against oxidative stress, protecting neurons and ensuring astrocyte functionality.

Summary: The purpose of this research was to investigate the negative effects of salt stress on soybean plants in terms of anatomical, morphological, nutritional, physiological, and biochemical parameters. The study found that concentrations of 50 to 200 mM Na+ significantly reduced the levels of K, Ca, and Mg in the plants, and had negative effects on photosynthesis, gas exchange, and photosynthetic pigments, which were likely caused by oxidative stress. Interestingly, at concentrations below 100 mM Na+, there were changes in epicuticular wax deposition, stomatal quantity and morphology, and leaf epidermis thickness in soybean plants. Overall, significant deleterious effects were observed in soybean plants under salt stress conditions above 100 mM Na+.

Summary: Assessing the toxicity of compounds on cell cultures is crucial for screening candidate molecules. Methylene blue (MB) and its related compounds can be used as indicators for cytotoxicity in live cells treated with DMSO and cisplatin. These dyes showed similar ability to assess cell toxicity compared to other commonly used indicators. This method provides a cost-effective alternative for in vitro cytotoxicity assays, with potential applications in drug screening.

Summary: This study investigated the effects of zinc oxide nanoparticles, nitric oxide donor, and their combination on the enzymatic and photosynthetic profile, as well as element accumulation, in rice plants. The results showed that these treatments increased the concentration of zinc and iron, and caused a mild disturbance in the antioxidant system. However, these disturbances did not significantly affect the yield, growth, or photosynthetic pigment production of rice plants.

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.

It was found that increasing the application of thiencarbazone-methyl center dot isoxaflutole resulted in increased stress on soil bacterial community structure and diversity. Increasing soil pH was recognized as a key factor in improving the diversity and structure of soil microflora. Supplemental use of nitrapyrin or modified attapulgite can increase soil pH and improve bacterial diversity.
