Summary: Pentachlorophenol (PCP), widely used in biocide and pesticide industries, causes oxidative damage to rat kidneys by increasing reactive oxygen species (ROS) and inhibiting antioxidant enzymes. PCP treatment also results in DNA damage, dysfunction of brush border membrane (BBM) enzymes, and increased plasma levels of creatinine and urea. These findings highlight the significance of PCP-induced oxidative stress in nephrotoxicity.

Summary: Although manganese is an essential trace element, overexposure can lead to toxicity and neurological dysfunction. This study investigated the mode of action of manganese toxicity on genomic integrity, focusing on DNA damage and repair mechanisms using Caenorhabditis elegans as a model organism. The results suggest that excessive manganese exposure can decrease genomic integrity and activate base excision repair.

Summary: The accumulation of DNA damage induced by oxidative stress is a crucial pathogenic factor of endothelial loss in diabetic vascular complications. It is still unclear whether aberrant glucose metabolism leads to defective DNA repair and accounts for hyperglycemia-induced endothelial oxidative stress injury. Our study showed that Foxo1 knockdown alleviated diabetes-associated retinal DNA damage and vascular dysfunction by promoting DNA repair mediated by the MRN-ATM pathway and restoring glycolysis capacity. Our findings suggest that defective glycolysis-dependent DNA repair could be a novel therapeutic target for diabetic vascular complications.

Summary: Ageing is a multi-factorial phenomenon, and accumulation of DNA damage or mutations is a dominant theory which contributes largely to the development of ageing and age-related diseases. Obesity is a complex chronic disease that affects multiple organs and tissues, and it has been found to be associated with higher loads of DNA damage. The present review focuses on the involvement of DNA metabolism in the development of obesity and how it accelerates ageing in mammals.

Summary: Oxidative stress plays a crucial role in spinal cord injury (SCI), causing damage to proteins, nucleic acids, lipids, cytoskeleton, and organelles. Oxidative DNA damage is likely a major contributor to the pathogenesis of SCI, although the evidence supporting this hypothesis is limited. Improved analysis methods are needed to uncover the role of DNA damage and repair in SCI.

Summary: In this study, it was demonstrated that soluble egg products of the parasite S. mansoni completely reprogram lipid and carbohydrate metabolism, causing oxidative stress-induced cell damage in the host parenchyma. The eggs take advantage of the host environment through metabolic reprogramming of hepatocytes and enterocytes, and induce DNA damage, promoting hepatocellular damage. These findings have important implications for international health efforts.

Summary: NOS-derived NO plays a critical role in protecting cyanobacteria from oxidative burst and maintaining their physiological balance. Addition of L-NAME inhibitor reduces NO accumulation, while addition of L-arginine increases NO synthesis. Inhibition of NOS leads to decreased growth and metabolic activity of cyanobacteria, as well as decline in photopigments, PSII efficiency, loss in membrane integrity and DNA damage, ultimately resulting in cell death.

Summary: In this study, a simple and sensitive method for the detection of N-acyl glycines (NAGlys) in plasma and urine samples using liquid chromatography-mass spectrometry (LC-MS) is described. The use of a derivatization reagent, 3-nitrophenylhydrazine, allows for quick reaction in aqueous solution without the need for a quenching step. NAGlys were first identified based on high-resolution LC-MS and subsequently quantified on triple quadrupole LC-MS. This approach enables a broader measurement of NAGlys and potential identification of diagnostic biomarkers for type II diabetes and diabetic complications.

Summary: A study was conducted to analyze the concentration and chemical speciation of PM2.5-bound lead (PM2.5-Pb) at a non-ferrous metal smelting site. It was found that PM2.5-Pb exposure has a significant impact on human absorption of lead and can cause cardiovascular damage. Animal simulation experiments were used to evaluate the relationship between PM2.5-Pb exposure and cardiovascular damage, and a risk assessment model was established. This research provides accurate estimates of the risk of PM2.5-bound heavy metals on the cardiovascular system and offers a scientific basis for future prevention and therapy of PM2.5-Pb-related diseases.

Summary: With the tightening restrictions on phthalate esters (PAEs), nonphthalate plasticizers (NPPs) are increasingly used. However, there is limited knowledge on the environmental occurrences, fate, and human exposure risks of many emerging NPPs. This study investigated the presence of NPPs and major PAEs in house dust, finding widespread occurrences of NPPs, such as ATBC, TCTM, TOTM, GMO, MO, and DiBA. Although current exposure may not pose significant health risks, potential hazards cannot be overlooked due to the lack of toxic threshold data and possible cocktail effects.

Summary: In this study, MALDI-2 and TIMS imaging were used to analyze lipids and metabolites in H295R adrenocortical MCTS. MALDI-2 detected more lipids and metabolites in MCTS compared to traditional MALDI, while TIMS successfully separated isomeric and isobaric ions in different regions of MCTS. MS/MS imaging experiments further confirmed the presence of these isomeric and isobaric ions. These findings demonstrate the potential of MALDI-2 and TIMS imaging as valuable tools for lipid and metabolite analysis in MCTS for various biological and medical research fields.

Summary: Tire wear particles (TWPs) are increasingly present in water, but little is known about their environmental consequences. In this study, TWP leachates were analyzed to identify potentially toxic organic substances using high-resolution mass spectrometry and toxicity identification. Thirteen substances were structurally identified, with cyclic amines found to be toxic to the tested algal species. Metabolomic analysis revealed differential metabolites associated with linoleic acid and purine metabolism, and oxidative stress was identified as a key factor in algal growth inhibition. This study highlights the risk posed by TWP leachable substances to aquatic organisms.

Summary: Existing and emerging persistent organic pollutants (POPs) pose significant threats to human health and economies. The development of effective mitigation strategies to remove or degrade these chemicals in the environment is crucial due to their persistence. Although various methods for electrocatalytic degradation of POPs have been developed in lab conditions, challenges such as harmful byproducts and limited working time hinder their practical application. This perspective work highlights high-entropy alloys as ideal catalyst materials for electrocatalytic degradation and discusses the use of AI to facilitate the design and testing of electrocatalysts. The challenges, negative effects, and solutions of applying AI in this process are also addressed.

Summary: Traditional diagnosis of infectious diseases relies on advanced analyzers in central hospitals, which is not sufficient for rapid control of epidemics, especially in resource-limited areas, raising the importance of the development of diagnostic systems for point-of-care testing (POCT). Here, researchers developed a simple and cost-effective digital microfluidic (DMF) platform in combination with colorimetric loop-mediated isothermal amplification (LAMP) for simple on-site diagnosis of diseases by the naked eye. The DMF-LAMP assay showed comparable sensitivity to conventional LAMP assay but was more efficient, and possessed a simple chip structure and high flexibility to integrate multiplex analysis.

A simple and sensitive method of NAGlys detection by LC-MS in plasma and urine samples is described, using 3-nitrophenylhydrazine as a derivatization reagent. This approach allows for a broader measurement of NAGlys, especially in the absence of authentic standards. The identified NAGlys have the potential to be diagnostic biomarkers for type II diabetes and diabetic complications.

Summary: Analysis of cis-diol compounds is crucial due to their important roles in various fields. Researchers have developed a matrix-assisted laser desorption/ionisation mass spectrometry (MALDI-MS) method to effectively analyse cis-diol compounds. This method utilizes a unique reactive matrix (BMQI) for in situ derivatization of cis-diol compounds, resulting in improved speed, reproducibility, and signal intensity, as well as reduced background interference. Additionally, the method has been successfully applied to the rapid screening and identification of sugar alcohols in different sugar-free foods.
