Optimizing a sustainable ultrasound assisted extraction method for the recovery of polyphenols from lemon by-products:comparison with hot water and organic solvent extractions [PDF]

open access: yes, 2018
Response surface methodology (RSM) based on a three-factor and three-level Box–Behnken design was employed for optimizing the aqueous ultrasound-assisted extraction (AUAE) conditions, including extraction time (35–45 min), extraction temperature (45–55 ...

A Glucose‐Responsive Intelligent Antibacterial and Oxygen‐Producing Hydrogel Promotes the Healing of Diabetic Wounds by Regulating Cellular Heterogeneity

open access: yesAdvanced Science, EarlyView.
We have developed a glucose‐triggered on‐demand drug delivery CF‐CPGaMPN hydrogel based on borate ester bonds. It inactivates microbes, releases oxygen, and enables on‐demand drug release in high‐glucose environments to promote healing of diabetic wounds. Single‐cell sequencing reveals that the CF‐CPGaMPN hydrogel significantly alleviates dysfunctional

Integrative Approaches to Treating Cellular Senescence in Kidney Disease

open access: yesAdvanced Science, EarlyView.
ABSTRACT Cellular senescence in the kidney plays a crucial role in the progression of acute kidney injury and chronic kidney disease. Therapeutic approaches targeting senescent cells, such as small molecule senolytic and senomorphic drugs, display efficacy in preclinical models.

Nitrogen‐Boosted H2O2 Production of Arginine‐Polyphenol Nanozyme Drives Oxidative Eustress for Hair Regeneration

open access: yesAdvanced Science, EarlyView.
PEA nanoenzymes are assembled from L‐arginine and EGCG. The nitrogen element in arginine enhances the thermodynamic feasibility of H2O2 production through PEA's oxygen reduction catalysis, enabling nitrogen‐dependent H2O2 release. Intradermal delivery of PEA via microneedles promotes efficient H2O2 synthesis, thereby stimulating regrowth in telogen ...

Prevention of Protein Glycation by Natural Compounds [PDF]

open access: yes, 2015
Non-enzymatic protein glycosylation (glycation) contributes to many diseases and aging of organisms. It can be expected that inhibition of glycation may prolong the lifespan.

Inactivation Rap2a in Endothelial Cell Prevents Pulmonary Fibrosis by Regulating Immune Microenvironment Through MAP4K4‐VCAM1 Signaling

open access: yesAdvanced Science, EarlyView.
We identified the endothelial RAP2A as a regulator of inflammatory endothelial activation in experimental lung fibrosis and suggest that targeting RAP2A‐mediated signaling may represent a potential strategy to modulate endothelial–immune crosstalk during fibrotic lung injury.

Storage effects of gel encapsulation on stability of chokeberry monomeric anthocyanins, procyanidins, color density, and percent polymeric color [PDF]

open access: yes, 2011
Chokeberries (Aronia melanocarpa) are an antioxidant-rich plant product due to their high content of polyphenols, especially anthocyanins and procyanidins.

Beyond antioxidants: the cellular and molecular interactions of flavonoids and how these underpin their actions on the brain [PDF]

open access: yes, 2010
The consumption of flavonoid-rich foods and beverages has been suggested to limit the neurodegeneration associated with a variety of neurological disorders and to prevent or reverse normal or abnormal deteriorations in cognitive performance.

AML‐Targeted Metal‐Polyphenol Nanoplatform Induces Ferroptosis‐ICD Cascade for Antitumor Immunity Boosting

open access: yesAdvanced Science, EarlyView.
Schematic illustration of the synthesis protocol for Fe‐SH@Fn, an AML‐targeted nanoplatform engineered to co‐deliver shikonin (SH) and Fe3+, synergistically boosting antitumor immunity via ferroptosis induction and immunogenic cell death (ICD). ABSTRACT Acute myeloid leukemia (AML) remains a therapeutic challenge due to its low immunogenicity and ...
