Oral bioavailability of quercetin from different quercetin glycosides in dogs [PDF]
British Journal of Nutrition, 2010 Although the flavonol quercetin is used as a supplement in commercial dog food, data on quercetin bioavailability in dogs are not available. Thus, we investigated quercetin bioavailability (measured as area under the concentration–time curve) in nine adult beagle dogs at an oral dose of 10 mg/kg body weight (b.w.).

Senolytic Therapy as a Preventive Strategy for Spine Degeneration and Pain
Advanced Science, EarlyView.Cellular senescence promotes inflammation, tissue degeneration, and chronic back pain. In sparc‐null mice, early oral administration of the senolytic agents o‐vanillin and RG‐7112 reduced senescent cell burden and pro‐inflammatory SASP signaling across intervertebral discs, endplates, vertebral bone, and spinal cord.

Preparation and characterization of quercetin-polyvinylpyrrolidone K-30 spray dried solid dispersion [PDF]
Journal of Pharmacy & Pharmacognosy Research, 2020 Context: The use of quercetin as a potential active pharmaceutical ingredient is limited by low aqueous solubility leading to low bioavailability. A spray-dried solid dispersion technique is used to increase the solubility and dissolution profiles of ...

Quercetin prevents pyrrolizidine alkaloid clivorine-induced liver injury in mice by elevating body defense capacity. [PDF]
PLoS ONE, 2014 Quercetin is a plant-derived flavonoid that is widely distributed in nature. The present study is designed to analyze the underlying mechanism in the protection of quercetin against pyrrolizidine alkaloid clivorine-induced acute liver injury in vivo ...

A simple and effective preparation of quercetin pentamethyl ether from quercetin [PDF]
Beilstein Journal of Organic Chemistry, 2018 Among the five hydroxy (OH) groups of quercetin (3,5,7,3',4'-pentahydroxyflavone), the OH group at 5 position is the most resistant to methylation due to its strong intramolecular hydrogen bonding with the carbonyl group at 4 position. Thus, it is generally difficult to synthesize the pentamethyl ether efficiently by conventional methylation.

Advanced Science, EarlyView.Lipid metabolic stress triggers ferroptosis in PDLSCs through the GSK3β/NRF2 pathway, thereby aggravating periodontal bone loss. Upregulated GSK3β promotes NRF2 ubiquitination and proteasomal degradation via β‐TrCP, suppressing NRF2 nuclear translocation and antioxidant target expression.

Advanced Science, EarlyView.This study reveals that Alzheimer's disease–linked APP expression in bone‐forming cells drives skull bone marrow remodeling and alters its vascular connections to the brain. These changes disrupt immune cell trafficking, cerebral blood flow, and cognition. Targeting bone marrow macrophages restores brain function, highlighting a previously unrecognized
