Ion Channel Dysfunction and Therapeutic Targeting in Salivary Gland Disorders

Oral Diseases, EarlyView.
ABSTRACT Objective Salivary gland hypofunction and xerostomia represent major clinical complications of radiation therapy, autoimmune disorders such as Sjögren's disease, and inherited epithelial ion transport defects. This review integrates current knowledge on ion channel dysfunction as a central mechanistic driver of salivary gland pathology and ...

Physiology and Transcriptomics Reveal Divergent Strategies of Mycorrhiza‐Mediated Drought Adaptation in Poplar

Plant, Cell &Environment, Volume 49, Issue 8, Page 5078-5094, August 2026.
ABSTRACT Mycorrhizal symbiosis shapes plant growth and stress resilience. Here, we compared physiological and molecular responses of poplars (P. x canescens) colonised by Paxillus involutus (Pi) or Cenococcum geophilum (Cg) under control conditions, drought stress and recovery.

Distinct Foliar Uptake Pathways for Phosphorus and Nano‐Hydroxyapatite in Potato Revealed By Synchrotron μCT and ³³P Imaging

Plant, Cell &Environment, Volume 49, Issue 8, Page 5563-5579, August 2026.
ABSTRACT Potato (Solanum tuberosum L.) has a high phosphorus (P) requirement, yet its shallow root system and the strong P‐fixing capacity of many soils limit the effectiveness of soil fertilisation. Foliar application of nano‐hydroxyapatite particles (nHAPs) has emerged as a promising alternative P fertilisation practice.

Growth Responses of Holcus lanatus L. (Velvet Grass) in Soils Contaminated with Cesium or Strontium

Soil Systems
Radiocesium (r-Cs) and radiostrontium (r-Sr) released from nuclear accidents (e.g., Chornobyl, Fukushima) and routine operations (reactors, reprocessing) pose environmental and health concerns.

Electrochemical Detection of Vanadium Using a Boron‐Doped Diamond Electrode as a Surrogate for Radioactive Heavy Metals

Electroanalysis, Volume 38, Issue 7, July 2026.
A boron‐doped diamond (BDD) electrode‐based anodic stripping voltammetry (ASV) method was developed for the electrochemical detection of radioactive heavy metals in nitric acid media using vanadium as a nonradioactive surrogate for neptunium. Systematic optimization identified an O‐terminated BDD electrode operated at a deposition potential of −1.2 V ...

Methionine Synthase Interacts With the Methionine Adenosyl‐Transferase MATα2 and the DNA Methyltransferase DNMT3b in the Nucleus

Journal of Inherited Metabolic Disease, Volume 49, Issue 4, July 2026.
This study shows that methionine synthase (MS) interacts with MATα2, responsible for SAM production, and the methyltransferase DNMT3b in the nucleus. These results support the idea that spatial compartmentalization of one‐carbon metabolism could play a major role in regulating the epigenome.
