Albiflorin‐Mediated MAP2K1 Targeting and HIF‐1 Signaling Inhibition Contribute to the Therapeutic Efficacy in Hyperuricemia‐Associated Cognitive Impairment

open access: yesHuman Mutation, Volume 2026, Issue 1, 2026.
This study investigated the therapeutic effects and mechanisms of Paeonia suffruticosa fruit pod extract (EMP) and its main component albiflorin (AF) on hyperuricemia‐associated cognitive impairment (HUA‐CI). A HUA‐CI mouse model was established, with cognitive function evaluated via Morris water maze.

Status of forest remnants invaded by tradescantia (Tradescantia fluminensis Vell.) following introduction of biocontrol beetles and manual clearance after three years

open access: yesNew Zealand Journal of Botany, Volume 63, Issue 4, Page 548-572, December 2025.
ABSTRACT We compared biocontrol beetles and manual clearing of tradescantia in forest remnants invaded by tradescantia (Tradescantia fluminensis Vell.) on the agriculturally modified Hikurangi floodplain, northern New Zealand, to inform best practice in enhancing native biodiversity. Four forest remnant study sites were used: two on dairy farms and two

Identification of Conserved Aquilegia Coerulea MicroRNAs and Their Targets [PDF]

open access: yes, 2012
Aquilegia is an emerging model organism that is phylogenetically intermediate between the core eudicot and monocot models, Arabidopsis and Oryza. In this study, we have used a comparative genomics approach to identify 45 Aquilegia microRNAs that comprise

Synthesis and Biological Evaluation of Theophylline Methyl 1,3,4-Oxadiazole as Anticancer Agents [PDF]

open access: yes, 2020
A series of theophylline methyl 1,3,4-oxadiazole small molecules were obtained via cyclization of theophylline-7-acetohydrazide with different benzoic acids. The compounds (IVa-j) were synthesized and characterized by using conventional methods.

Physiological roles of lignins – tuning cell wall hygroscopy and biomechanics

open access: yesNew Phytologist, Volume 248, Issue 6, Page 2674-2706, December 2025.
Summary Lignins constitute the second most abundant carbon‐storing biopolymers in the biosphere. These phenolic polymers accumulate in different concentrations, compositions, and localisations within and between cell wall layers and cell types. Lignins were acquired during plant terrestrialisation 450 million years ago, and the diversification of their

Transcriptomic and enzymological evidence for plastid peptidoglycan synthesis in the gymnosperm Picea abies

open access: yesThe Plant Journal, Volume 124, Issue 5, December 2025.
Significance Statement Peptidoglycan (murein) biosynthesis is involved in chloroplast division in mosses, while Arabidopsis MurE mutants are defective in chloroplast development. We have shown that the gymnosperm Picea abies expresses 11 genes of the peptidoglycan biosynthesis pathway, and that P.

Cloning and Functional Characterization of Two 4-Coumarate: CoA Ligase Genes from Selaginella moellendorffii

open access: yesMolecules, 2018
Selaginella is an extant lycopodiophyte genus, which is representative of an ancient lineage of tracheophytes. The important evolutionary status makes it a valuable resource for the study of metabolic evolution in vascular plants. 4-coumarate: CoA ligase
