G‐Quadruplexes: Structural Diversity and Emerging Roles in Biomolecular Condensation

Advanced Science, EarlyView.
G‐quadruplexes (G4s) fold into diverse intra‐ and intermolecular structures, positioning them as emerging regulators of biomolecular condensation. Mechanistically, G4s autonomously form condensates, act as structural platforms to initiate and stimulate condensation, or induce phase transitions.

Ascorbic Acid Mitigates Salt Stress in Tomato Seedlings by Enhancing Chlorophyll Synthesis Pathways

Agronomy
Salt stress is a critical abiotic factor that adversely affects plant growth and productivity by impairing photosynthesis. This study explores the impact of exogenous ascorbic acid (AsA) on the photosynthetic performance of tomato seedlings (Solanum ...

Peptide‐directed nanovehicles enabling tumor‐selective ROS amplification and antitumor immunity

VIEW, EarlyView.
Cancer cells are vulnerable to oxidative stress, yet exploit immune tolerance to escape destruction. In contrast, their metabolic profile is markedly altered to support rapid proliferation, accompanied by elevated production of reactive oxygen species (ROS).

The effects of gasotransmitters inhibition on homocysteine acutely induced changes in oxidative stress markers in rat plasma [PDF]

Scripta Medica, 2019
Background: The importance of homocysteine (Hcy) is increasingly recognized in last few decades as an independent risk factor for atherosclerosis and thrombosis, but there is lack of data referring to influence of Hcy on plasma oxidative stress ...

GmDOF3.1‐GmCPX Module Regulates Nodulation and Nitrogen Fixation Abilities in Soybean

Plant Biotechnology Journal, EarlyView.
ABSTRACT Soybean nodule nitrogen fixation is very important, which can provide a large amount of nitrogen supply for its own growth and that of other crops, but the mechanism is largely unclear. In the present study, a coproporphyrinogen oxidase gene, GmCPX, was identified to facilitate soybean nodulation and nitrogen‐fixation under the regulation of ...

Maternal nutrition as a key determinant of placental and developing blood–brain barrier xenobiotic protective functions

The Journal of Physiology, EarlyView.
Abstract figure legend Suboptimal maternal nutrition alters placental and developing blood–brain barrier (BBB) protective function and is associated with increased fetal brain vulnerability. In the placenta, nutritional adversity may reduce the exchange surface area and promote meta‐inflammation, compromising barrier efficiency in a model‐ and context ...

Isothiocyanates as Ferroptosis Inducers to Promote Cancer Cell Death

Phytotherapy Research, Volume 40, Issue 8, Page 5119-5131, August 2026.
ABSTRACT Cancer remains a leading cause of global mortality, with the therapeutic efficacy of anticancer drugs often hampered by late diagnosis and the development of chemotherapy resistance. Ferroptosis is an iron‐dependent form of regulated non‐apoptotic cell death driven by lipid peroxidation.

Ruthenium(II) and Osmium(II) Probes Based on the BODIPY Fluorophore for the Detection of Carbon Monoxide and Viscosity in Biological Environments

Advanced Sensor Research, Volume 5, Issue 7, July 2026.
Ruthenium and osmium vinyl complexes incorporating BODIPY fluorophores show highly selective, turn‐on detection of carbon monoxide (CO) in biological environments. Two different designs are compared and used to achieve sensitive in cellulo sensing of CO.

Supramolecular Coordination Platforms for Smart Theranostics: Leveraging the Dynamic Molecular Networks of Metal–Polyphenol Assemblies

Aggregate, Volume 7, Issue 7, July 2026.
In this review, we summarize the recent developments of metal–polyphenol networks (MPNs) as a highly versatile and functionally integrated supramolecular assembly platform. We also discuss their pivotal role in steering biomedical materials away from conventional single‐function designs and toward intelligent, unified diagnostic and therapeutic ...
