Resolution and Quantitation of Ribonucleosides and Deoxyribonucleosides in Digested Genomic DNA by UHPLC–MS/MS

open access: yesBiomedical Chromatography, Volume 40, Issue 10, October 2026.
ABSTRACT Deoxyuridine (dUrd) is often misincorporated into genomic DNA in cancer patients receiving antimetabolite chemotherapy. This activates base excision repair and recruits ataxia telangiectasia‐mutated and Rad3‐related (ATR), which coordinates DNA repair with nucleotide metabolism by facilitating ribonucleotide reductase (RNR) activity ...

The downward legacy of a phytoplankton bloom in the oligotrophic North Pacific Subtropical Gyre

open access: yesLimnology and Oceanography, Volume 71, Issue 10, October 2026.
Abstract Ocean particles are a heterogeneous collection, including living and dead cells, feces, mucus‐rich aggregates, and mineral shells and frustules. In the well‐lit upper ocean, phototrophic processes fuel production of particulate matter; however, only a relatively small percentage (< 10% per day) of this material (mostly detrital) escapes the ...

A High‐Throughput SPR‐Based Array for Quantitative Profiling of Glycosaminoglycan–Protein Interactions

open access: yesProteoglycan Research, Volume 4, Issue 4, October 2026.
ABSTRACT Glycosaminoglycans (GAGs) are linear, negatively charged, polysaccharides that mediate a wide variety of biologically critical interactions with proteins, underpinning growth factor signaling, extracellular matrix assembly, and numerous disease processes.
