In conclusion, 26.9 nm citrate-coated AgNPs are capable of gaining access to the brain of mice and causing electric conductivity and relative permittivity damage along with a high degree of cellular toxicity in the brain tissue. Therefore, the present study highlights, for the first time, the adverse effects of the citrate-coated AgNPs to the brain of mice and raises the concern of their probable neurotoxic impacts which is helpful for conclusive interpretation of future behavioral and potential neurodegeneration-based aspects. It would be of interest to investigate citrate-coated AgNPs mediated axonal relevant-signal transduction levels in future studies.Nanotechnologies and different types of nanomaterials belong in present day to intensively studied materials due to their unique properties and diverse potential applications in, e.g., electronics, medicine, or display technologies. Together with the investigation of their desired beneficial properties, a need to investigate and evaluate their influence on the environment and possible harmful effects towards living organisms is growing. This review summarizes possible toxic effects of nanomaterials on environment and living organisms, focusing on the possible bioaccumulation in organisms, toxicity, and its mechanisms. The main goal of this review is to refer to potential environmental risks rising from the use of nanomaterials and the necessity to deal with the possible toxic effects considering the growing interest in the wide-scale utilization of these materials. Electron paramagnetic resonance spectroscopy as the only analytical technique capable of detecting radical species enables detection, quantification, and monitoring of the generation of short-lived radicals often coupled with toxic effects of nanomaterials, which makes it an important method in the process of nanotoxicity mechanism determination.To investigate the mechanism of nitrogen removal by anthracites and enhance the nitrogen removal efficiency in constructed wetland, three kinds of layered double hydroxides (MgFe-LDHs, MgCo-LDHs, MgAl-LDHs) were prepared by co-precipitation under alkaline conditions and coated in situ on the surface of anthracites to synthesize core-shell anthracites/Mg-LDHs composites. Experiments with different treatments (columns loaded with original anthracites and anthracite/Mg-LDH composites) were conducted to study the nitrogen removal efficiency of domestic wastewater in constructed wetlands. The results of nitrogen removal experiments showed that the anthracite/MgAl-LDH composite had the best performance with average removal rates of 53.69%, 72.91%, and 47.43% for TN, NH4+-N, and organic nitrogen, respectively. BMS-232632 price Modification changed the denitrification mode of the anthracites. The data of adsorption isothermal experiments were fitted better with the Freundlich model. The amount of ammonifier, nitrosobacteria, nitrobacter, and denitrifier on the surface of the Mg-LDH-modified anthracite was higher than that of the original anthracite. The performance of the anthracite in removing nitrogen was attributed to physical interception, chemical adsorption, and biological degradation. Moreover, the modified anthracites were superior to the original anthracite in the chemical adsorption and biodegradation, which indicated that coating the Mg-LDHs on the surface of common anthracite was a potential method to improve the nitrogen removal efficiency of domestic wastewater and to restore the eutrophic water body.The burden of five main air pollutants, including CO, O3, NO2, SO2, and PM2.5, on the emergency department visits (EDVs) during January 2016-December 2019 due to all cardiovascular diseases was assessed in Tehran by using a time-series model. The pollutants data were collected from Iran Department of Environment including 10 air pollution monitoring stations for the period of our study. Cumulative relative risk and attributable number/fraction were calculated for each pollutants by a Quasi-Poisson time-series regression and distributed lag non-linear model (DLNM). The maximum lag was set to 14 days because harvesting effect is more likely happened during few days. We used percentile 25 as reference value in order to calculate cumulative relative risk and attributable fraction. About 69,000 patients with cardiovascular symptoms have been admitted into the hospital during 4 years. The cumulative relative risk during the 14 days was 1.13 (1.01, 1.26), 1.15 (1.02, 1.29), and 1.08 (1.01, 1.18) for CO, NO2, and PM2.5, respectively. The numbers attributed to all values of CO were more than others; about 3800 EDVs were significantly attributed to CO, of which over 3000 were significantly attributed to high values of the pollutant. Low values of all pollutants were, not surprisingly, responsible for low number of EDVs. PM2.5, CO, and NO2 were responsible to considerable attributable number of EDVs. Our study emphasizes the need for local authorities to establish a program to reduce the air pollution in Tehran.European Reference Networks (ERNs) were founded on the principle that many rare disease (RD) issues are pan-European and any single Member State cannot solve them alone. In 2021, ERNs are already in the deployment stage; however, their day-to-day functioning and realization of their potential are still severely hampered by many challenges, including issues in governance and regulation, lack of legal status, insufficient and unsustainable funding, lack of ERN integration into national systems, endangered collaboration with UK RD experts due to Brexit, insufficient exploitation of ERN potential in RD research, underappreciation of highly qualified human resources, problems with the involvement of patient representatives, and still unclear place of ERNs in the overall European RD and digital ecosystem. Bold and innovative solutions that must be taken to solve these challenges inevitably involve pan-European collaboration across several sectors and among multistakeholder RD communities and in many cases crucially rely on the constructive dialogue and coherent, united decisions of national and European authorities that are based on common EU values. Importantly, unresolved challenges may have a strong impact on the further sustainability of ERNs and their ability to realize full potential in addressing huge unmet needs of RD patients and their families.
