STING signaling contributes to methotrexate-induced liver injury by regulating ferroptosis in mice.

Methotrexate (MTX), an anti-metabolite agent, is a widely used chemotherapeutic anticancer drug, but its hepatotoxicity severely limits its clinical application. Nevertheless, the precise mechanisms of MTX-caused liver damage are extremely intricate and still need to be fully clarified. In the current study, we investigated the role of the STING-ERS-ferroptosis axis in MTX-triggered hepatic toxicity in vivo and in vitro models.

Nitrification is the key step of biological nitrogen removal process, thus researching the effect of salinity on nitrification is significant. In this article, the research progress of the impact of salinity on wastewater biological nitrification process was summarized.

[Watershed water environment pollution models and their applications: a review].

Watershed water environment pollution model is the important tool for studying watershed environmental problems. Through the quantitative description of the complicated pollution processes of whole watershed system and its parts, the model can identify the main sources and migration pathways of pollutants, estimate the pollutant loadings, and evaluate their impacts on water environment, providing a basis for watershed planning and management. This paper reviewed the watershed water environment models widely applied at home and abroad, with the focuses on the models of pollutants loading (GWLF and PLOAD), water quality of received water bodies (QUAL2E and WASP), and the watershed models integrated pollutant loadings and water quality (HSPF, SWAT, AGNPS, AnnAGNPS, and SWMM), and introduced the structures, principles, and main characteristics as well as the limitations in practical applications of these models.

[Research advances in identifying nitrate pollution sources of water environment by using nitrogen and oxygen stable isotopes].

Water body' s nitrate pollution has become a common and severe environmental problem. In order to ensure human health and water environment benign evolution, it is of great importance to effectively identify the nitrate pollution sources of water body. Because of the discrepant composition of nitrogen and oxygen stable isotopes in different sources of nitrate in water body, nitrogen and oxygen stable isotopes can be used to identify the nitrate pollution sources of water environment.

[Methods for the assessment of organic compounds biodegradability: A review].

There are plenty of methods used for the assessment of organic compounds biodegradability, but lack of comprehensive literatures in systematically introducing the assessment methods and guiding the choice of the methods. This paper briefly introduced the indicative parameters in assessing organic compounds biodegradability and the assessment methods of aerobic and anaerobic biodegradation, with the focus on the principles and criteria in the choice of the assessment methods, and analyzed in detail the reasons for the differences in the biodegradation rates of organic compounds when different test methods were adopted. Taking the standards established by the Organization for Economic Co-operation and Development (OECD) as an example, the process of choosing and applying the assessment methods was introduced, the systematic method-choosing route was integrated, and the advantages of the OECD standard methods were pointed out.

[Thermophiles and their working mechanisms in degrading excess sludge: a review].

Activated sludge process is widely used in treating a wide variety of wastewater, but the by-product is the large amount of excess sludge. To treat the excess sludge properly could spend 25%-60% of the total cost of wastewater treatment, while improperly treating the sludge could cause serious secondary pollution. Therefore, the reduction of excess sludge is becoming a rising challenge.
