Summary: A large amount of fish side streams are produced each year, causing significant economic and environmental issues. The study aimed to isolate high-value compounds from fish by-products and determine their effects on cell proliferation, as well as the influence of minerals and metals and the potential enhancement of cell proliferation by dietary antioxidants. The results showed negative effects on cell proliferation at high concentrations of hydrolyzed fish protein and collagen samples. However, pre-treatment with certain antioxidants increased cell proliferation. The highest mineral concentrations were found for P, Ca, and Mg, while metals appeared at almost undetectable levels in bioavailable fractions.

Summary: This study examined the metal bioaccessibility in size-fractionated zinc smelting slags and found significant differences in bioaccessible fractions of heavy metals but no statistical difference among different particle sizes. The bioaccessible metal fractions were mainly controlled by carbonate bound phases, and the solubility behaviors of toxic elements in the smelting slags were dominated by soluble metal-bearing mineral phases and absorbable Fe, Mn, and Al-rich minerals.

Summary: This study evaluated the applicability of magnetic methods for monitoring pollution levels in public playgrounds by combining magnetic measurements, geochemical analyses, particle-based techniques, and bioaccessibility data. The study found high levels of magnetic components in playground sands, with dominant minerals being magnetite and/or maghemite. The correlation analysis between magnetic variables and metal(loid) contents identified χ(ARM) as a more effective indicator for detecting anthropogenic load in playground sand samples.

Summary: We propose a novel approach for the Metagenomic Geolocation Challenge that utilizes random projection of sample reads. This approach directly uses k-mer composition to characterize samples, eliminating the computationally demanding step of aligning reads to microbial reference sequences. Our findings demonstrate that k-mer representations carry sufficient information to determine the origin of metagenomic samples and that this reference-free approach requires less computation compared to previous methods.

Summary: Recombinant plasmid vectors are versatile tools that have facilitated discoveries in various fields. However, errors can be introduced during the process of creating recombinant DNA, making sequence validation essential. While Sanger sequencing is the current standard for plasmid validation, it has limitations in sequencing complex secondary structures and scaling for full-plasmid sequencing. This article introduces OnRamp, an alternative method that combines the advantages of high-throughput sequencing and Sanger sequencing by leveraging nanopore's long-read sequencing technology. It provides customized wet-lab protocols and an analysis pipeline for plasmid preparation and data processing, aiming to make long-read sequencing more accessible for routine plasmid validation.

Summary: Increasing the use of hygienic high-touch surfaces with antimicrobial properties is important for reducing the spread of bacteria and infections. This study found that the antimicrobial efficacy of surfaces treated with silver-doped phosphate glass was dependent on the type of bacteria but not influenced by surface weathering. The amount of silver-doped additive also played a role in the effectiveness of the antimicrobial properties. Cleaning the surfaces with an oxidizing agent was more efficient in killing bacteria compared to a biologically degradable agent. This study highlights the importance of using surfaces with antimicrobial properties and the effectiveness of certain cleaning agents.

Summary: The physicochemical characterization of AMPs revealed their complexity in size, shape, and chemistry. The AMPs exhibited concentration-dependent effects on the cytoskeleton, mitochondria, and cell membranes. Metabolomics and lipidomics analysis provided insight into the inflammation-related metabolites and extensive membrane remodeling induced by AMPs. Overall, AMP exposure resulted in internalization, oxidative stress, cytoskeleton disruption, mitochondrial activation, membrane remodeling, and metabolic reprogramming of lung epithelial cells and macrophages. Integrating Cell Painting with metabolomics and lipidomics offers an advanced nanosafety methodology to capture cellular and molecular phenotypes and understand the biological mechanisms of (nano)particle exposure.

Summary: This study demonstrates that the addition of 2% by weight of MoS2 to Mo feedstock significantly improves crack mitigation in Mo-based micro-lattice structures produced by selective laser melting. The enhanced crack inhibition is attributed to the formation of Mo2S3, reduced lattice strain, and decreased residual stresses. The addition of MoS2 hinders stress corrosion cracking and surface oxidation cracking, as confirmed by increased polarization resistance. However, it also leads to increased corrosion current density and occurrence of different types of corrosion. The strategy of adding MoS2 to Mo feedstock enables the fabrication of high-temperature micro-lattice components with improved corrosion resistance properties.

Summary: In October 2022, the World Health Organization reevaluated the toxic equivalency factors (TEFs) for chlorinated dioxin-like compounds in a panel convened in Lisbon. This effort utilized an updated database, Bayesian dose response modeling, and meta-analysis to derive Best-Estimate TEFs. Applying these new TEFs may result in lower total toxic equivalents for dioxin-like chemicals.
