Pre‐treatment with extraction solvent yields higher recovery: Method optimization for efficient determination of polycyclic aromatic hydrocarbons in organic‐rich fine‐textured wastes

open access: yesJournal of Environmental Quality, EarlyView.
Abstract Fluid fine tailings (FFT) contain numerous organic compounds, including polycyclic aromatic hydrocarbons (PAHs). Growing concerns of PAH toxicity warrants monitoring for environmental consequences and natural attenuation. Conventional Soxhlet extraction yields low (∼50%–60%) recovery of PAHs (naphthalene, phenanthrene, pyrene, dibenzofuran ...

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

Multiomics Reveal Associations Between CpG Methylation, Histone Modifications and Transcription in a Species That has Lost DNMT3, the Colorado Potato Beetle

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Despite lacking DNMT3, EM‐seq revealed CpG methylation in the Colorado potato beetle. CUT&Tag analysis showed an association of H3K36me3 and H3K27ac with transcription, with H3K36me3 mirroring CpG methylation, demonstrating epigenetic flexibility.

Analysis of Gene Expression in Aedes aegypti Suggests Changes in Early Genetic Control of Mosquito Development

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
ABSTRACT Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for studying its embryogenesis due to difficulties in removing its rigid chorion and achieving effective fixation for in situ hybridization. Here, we present novel methodologies for fixation, dechorionation, DAPI staining, and in situ hybridization, enabling ...

Perivascular Space Burden in Children With Autism Spectrum Disorder Correlates With Neurodevelopmental Severity

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Cerebral perivascular spaces (PVS) are involved in cerebrospinal fluid (CSF) circulation and clearance of metabolic waste in adult humans. A high number of PVS has been reported in autism spectrum disorder (ASD) but its relationship with CSF and disease severity is unclear.
