Summary: Coal combustion is a major source of global electricity, but it also generates a significant amount of coal ash residues. This article reviews the environmental damage caused by coal ash and discusses three commonly used risk assessment methodologies: leaching assessment, groundwater assessment, and toxicity testing. It also emphasizes the need for sustainable and selective methods for recovery of critical elements from coal ash.

Summary: This study aimed to investigate the pollution level of trace elements in farmland soil and crops collected in one of Ecuador's most important gold mining areas. The results showed that the concentration of certain elements in the soil exceeded the quality guidelines for agricultural soils, while the concentration in crops exceeded the maximum permissible levels set by FAO. The health risk assessment revealed that inhabitants of the study area are exposed to developing carcinogenic and non-carcinogenic effects due to long-term consumption of food with high trace elements.

Summary: Risk assessment of heavy metals is critical in controlling and preventing risks of foodborne diseases. Fish can be used as bioindicators for exposure to potential toxic elements (PTEs), which can represent potential risks for humans. The study collected data on PTEs in fish from different fishery regions in Iran and used Monte Carlo simulation to assess health risks. The results showed that mercury intake from fish in all regions exceeded safe levels for children, and consumers of fish from the southern sea were at risk of mercury adverse health effects. The study also highlighted the high carcinogenic risk of cadmium in fish from all regions. Overall, the consumption of fish in Iran may pose health complexities for consumers, especially infants and pregnant women.

Summary: In recent years, there has been increasing attention on the deposition of toxicants from road traffic and its impact on food items. This study focused on heavy metal pollution in street vended noodles and its association with different environmental sources. The results showed that several heavy metals exceeded the allowable limits for food products. Street vended noodles sold on high traffic density streets had higher levels of heavy metal contamination due to atmospheric deposition. Health risk assessment indicated an elevated non-carcinogenic hazard to consumers of such street vended food.

Summary: The study reveals that the concentrations of cadmium and lead in the soils of Neyriz, Iran exceed global standard thresholds by 10-40 times, while copper and zinc levels are below the thresholds, indicating contamination from geological formations and Ophiolitic rock masses in the area. Natrual factors such as geological formations can contribute to soil and plant pollution, in addition to pollution caused by human activities.

Summary: This study presents new data on the distribution and health risks of arsenic and other heavy metals in groundwater in Haridwar, India. The dominant contaminant in the groundwater was found to be iron, followed by manganese, arsenic, copper, nickel, lead, chromium, and cadmium. The study also identified the likely mechanism of arsenic release and assessed the level of heavy metal pollution and associated health risks. The results show that the heavy metal pollution level was moderate to low, but there were significant non-carcinogenic and carcinogenic health risks associated with arsenic and heavy metal contamination.

Summary: This study investigated the concentration of nine heavy metals in Oreochromis niloticus and Ipomoea aquatica in Agodi reservoir, Nigeria. The results showed that the metals accumulated more in O. niloticus than in I. aquatica. Most of the examined metals exceeded the safety limit, and O. niloticus had lower tolerance for heavy metals. Additionally, metal concentration and ecological risk quotient were higher in the wet season for O. niloticus.

Summary: Laguna de Bay in the Philippines, the third largest lake in Southeast Asia, is a significant source of freshwater fish. However, unregulated discharge of industrial, domestic, and agricultural wastewaters has led to heavy metal contamination in the lake, which affects the toxicity of the popular Asiatic clam. The study found that the western part of the lake had higher concentrations of certain heavy metals in the sediment compared to the eastern part, and there were correlations between the sediment and the Asiatic clam.

Summary: The use of C2 servers in cyberattacks has increased significantly, with attackers using DGA technique to hide their servers. Existing techniques for binary classification of domain names have issues with real-time detection and sensitivity to data. This paper proposes the DTFS-DGA model, which combines neural networks and traditional machine learning models to detect DGA in real-time without relying on reverse engineering and being insensitive to data size.

Summary: In this study, various parameters of oxidative stress, immune response, and abnormalities in the erythrocyte nucleus of Labeo rohita inhabiting the polluted Kshipra River, India, were measured. The heavy metal concentrations in the river water were in the order of Ni > Fe > Cd > Cr > Mn > Zn > Cu. The fish showed increased levels of antioxidant enzymes in gills, liver, and gut compared to the reference fish, but decreased levels of GST and GSH. Heavy metals also caused immunosuppression and histopathological changes in the fish. These findings highlight the potential impact of heavy metal-induced stress on fish inhabiting polluted river water and the importance of pollution control.

Summary: The renin-angiotensin system (RAS) is crucial for regulating arterial pressure and fluid balance, and the angiotensin type 2 receptor (AT2R) plays a protective role in pathophysiological conditions. This study investigated the impact of single nucleotide polymorphisms (SNPs) on AT2R and its interactions with agonist and antagonist molecules. Computational analysis and molecular dynamics simulations revealed that certain mutations affect the protein conformation and ligand binding. These findings have implications for the development of better medications and future in vitro and in vivo studies.

Summary: This study aimed to identify potential new drug targets/candidates for multi-drug-resistant Mycobacterium tuberculosis (Mtb) through computational techniques. The protein structure of ribonuclease VapC2 of Mtb H37Rv was analyzed, and docking studies were performed with 22 anti-TB drugs. Rifampicin showed the best binding energy and was selected as the parent molecule for designing derivatives. One of the derivatives, RIF-155841, showed activity in inhibiting VapC2. Molecular dynamics simulations confirmed the stability of the VapC2-RIF155841 complex, and a chemical synthesis scheme was designed for future validation.

Summary: The aim of this study was to evaluate the anticancer efficacy of chlorojanerin against different cancer cells. The effects of chlorojanerin on cell cytotoxicity, cell cycle arrest, and cell apoptosis were investigated using various assays. RT-PCR was used to analyze the expression levels of apoptosis-related genes. Docking simulations were employed to study the binding preferences of chlorojanerin with Bcl-2. The results showed that chlorojanerin inhibited cell proliferation dose-dependently and had a promising effect against A549 lung cancer cells. The inhibition of cell growth was associated with G2/M phase cell cycle arrest and apoptosis induction. We also found that chlorojanerin altered the expression of genes involved in apoptosis initiation and could fit into the active site of Bcl-2 according to docking simulations. These findings suggest that chlorojanerin has potential as a therapeutic agent in lung cancer treatment.

Summary: This study investigates the interaction between the sodium channel blocker amiloride and human serum albumin. The results show that amiloride specifically binds to a specific site on HSA and the complex is stabilized by van der Waals hydrogen-bonding and hydrophobic interactions. FRET analysis demonstrates that the distance between amiloride and Trp214 is crucial for efficient quenching. UV-Vis spectroscopy and circular dichroism indicate minor structural changes in HSA after binding. Molecular dynamics simulations provide further evidence of stable HSA-AML complex formation.
