Ganoderic Acids Alleviate Neuroinflammation by Targeting Myeloid Differentiation Factor 2 for Ischemic Stroke Therapy

Exploration, EarlyView.
Ganoderic acids confer neuroprotection in ischemic stroke by directly targeting MD2, thereby blocking MD2/TLR4 complex formation and downstream MAPK and NF‐κB activation. This suppresses microglia‐driven neuroinflammation and mitigates cerebral ischemic injury.

One‐Stone‐Three‐Birds Biomimetic Oral Targeting Delivery Strategy for On‐Demand Controlled Drug Release and Intervertebral Disc Degeneration Therapy

Exploration, EarlyView.
ABSTRACT Intervertebral disc degeneration (IDD) is a multifactorial condition characterized by excessive inflammation, immune dysfunction, and metabolic disorders. Current therapeutic strategies primarily rely on local injection, a traumatic approach associated with risks of tissue damage and infection.

Enhancing the Sensitivity of Colorimetric Aptasensor Through Cd2+‐Thymine Interactions in ssDNA Loops for Food Contaminant Detection

Food Safety and Health, EarlyView.
This picture illustrates a novel aptamer‐based colorimetric assay, which demonstrates that high sensitivity, selectivity, and reliability for the rapid detection of cadmium ions (Cd2+) in water. Molecular dynamics (MD) simulations have revealed that the complexes are more stable, with Cd2+ binding more tightly to the thymine (T) within the aptamer loop.

Isorhamnetin Alleviates Renal Fibrosis Induced by Renal Tubular Epithelial Cell Senescence Via Inhibition of the IL‐6/IL‐6R Signaling Pathway

iMetaMed, EarlyView.
IL‐6 from RTECs upregulates TGF‐β in macrophages, promoting fibroblast transdifferentiation. Isorhamnetin inhibits this effect. ABSTRACT Chronic kidney disease (CKD) is a major global health issue. Kidney fibrosis is a key mechanism leading to end‐stage renal disease.

Biogenic Synthesis of Silver and Iron Nanoparticles Derived From Grewia Optiva Leaf Extract: A Novel Approach for Antidiabetic, Anticoagulant and Anti‐Inflammatory Therapies

International Journal of Chemical Kinetics, EarlyView.
ABSTRACT This study presents the green synthesis of silver (Ag‐NPs) and iron nanoparticles (Fe‐NPs) using aqueous leaf extract of Grewia optiva as a natural reducing and stabilizing agent. The extract was prepared using a Kjeldahl apparatus under controlled heating. Nanoparticle synthesis was optimized by varying pH, temperature, and salt concentration,
