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 ...

METTL18 is Required for Developmental, Metabolic, and Endocrine Regulation of Mammalian Growth

open access: yesThe FASEB Journal, Volume 40, Issue 17, 15 September 2026.
METTL18 is essential for histidine Nτ‐methylation of proteins, normal embryonic development, iron and lipid metabolism, and hormone signaling pathways that support postnatal growth in mice. The main points of this study are as follows: First, mouse METTL18 catalyzes histidine Nτ‐methylation. Next, Mettl18 KO embryos are significantly smaller than their

Insights into the effects of reproductive phase thermal stress on physiology and yield‐related traits of rice cultivars

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract High temperatures lead to a significant drop in rice (Oryza sativa L.) productivity worldwide, especially during the reproductive stage. This research was piloted to evaluate 10 promising rice cultivars for their ability to withstand high‐temperature stress (HS) during the reproductive phase and to assess the impact on physiology and yield ...

Five New Iridoids From the Leaves of Viburnum macrocephalum f. macrocephalum and Their Free Radical Scavenging Activity

open access: yesChemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Five new iridoids, viburetins D–H, featuring dioxatricyclodecane and ring‑opened monocyclic skeletons, are isolated from the leaves of Viburnum macrocephalum f. macrocephalum, enriching the chemical diversity of Viburnum. Preliminary DPPH and ABTS assays reveal varying degrees of radical scavenging activity.

Constituents From the Flowers of Viburnum macrocephalum f. macrocephalum and Their α‐Amylase and α‐Glucosidase Inhibitory Activities

open access: yesChemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Two new cadinane‑type sesquiterpenes, viburetones A and B, were isolated from Viburnum macrocephalum flowers, marking the first cadinane skeletons in this genus. Viburetone A showed dual α‑amylase and α‑glucosidase inhibition comparable to acarbose, and docking clarified its binding.
