Summary: An analytical method based on liquid chromatography coupled to mass spectrometry was validated to quantify five perfluorinated carboxylic acids in wastewater produced in a megacity. Short-chain PFCA were abundant, while concentrations of PFOA and PFUnA remained lower in both sampling sites. The study found that furtive discharges of municipal and industrial wastewater increased the levels of short-chain PFCA, while those of PFOA and PFUnA were depleted.

Summary: Eighteen PFASs were studied in surface waters of four river basins in Portugal. All sampling sites showed contamination in at least one season. The most frequent PFASs varied between dry and wet seasons. PFOS and PFOA were the most frequent in dry season, while PFOA and PFBS were the most frequent in wet season. The potential environmental risks of PFASs were evaluated based on risk quotient (RQ), showing generally low risk except for PFTeA which posed high risks for fish and daphnids.

Summary: In this study, the metabolism of celastrol in vivo and in vitro was comprehensively characterized using ultra-high-performance liquid chromatography coupled with hybrid triple quadrupole time-of-flight mass spectrometry. A total of 43 metabolites were identified and characterized, and it was found that the biotransformation capacity of the intestinal tract exceeded that of the liver. These findings provide a basis for understanding the pharmacological mechanisms of celastrol and have potential implications for clinical applications.

Summary: Reversed-phase HPLC is commonly used in MS-based proteomics for peptide separation, with particle-packed capillary columns being predominantly used in nanoflow HPLC systems. Despite capillary columns being a standard for many years, they are expensive and have short lifetimes, leading many laboratories to produce their own in-house packed columns.

Summary: Nowadays, the increased agro-industrial activities have led to a potential worldwide risk for the environment as traditional wastewater treatment plants are unable to eliminate recalcitrant organic contaminants. An innovative hybrid photocatalytic nanofiltration reactor (PNFR) prototype has emerged as a promising solution by combining photocatalytic degradation with size exclusion capacity. The PNFR unit exhibits encouraging removal efficiencies against pesticides and allows for the recycling of real agro-wastewater.

Summary: Free chlorine (HOCl) and monochloramine (NH2Cl) are cost-effective oxidants for water reuse and provide protection against residual contaminants. In UV advanced oxidation processes (UV-AOPs), UV/H2O2 and UV/HOCl were found to remove a greater fraction of organic compounds, form fewer transformation products, and reduce non-target features to the greatest extent compared to UV/NH2Cl and UV/ambient. Additionally, UV/H2O2 resulted in fewer chlorinated byproducts and a slight increase in the oxidative stress response in bioassays.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

The functionalized IVP showed a high mercury adsorption capacity and a machine learning model was developed to predict the amount of mercury removed. Furthermore, the functionalized IVP can be regenerated and reused, providing a sustainable and cost-effective adsorbent.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
