pinocembrin/infarction

Oxidative stress plays an important role in the pathogenesis of ischemia/reperfusion (I/R) injury induced by cardiac dysfunction. Pinocembrin (5,7-dihydroxyflavanone) is a flavonoid found in propolis and in rhizomes of fingerroot (Boesenbergia pandurata) that is reported to have pharmacological

Previous studies indicate that myocardial infarction (MI) may contribute to atrial fibrillation (AF). Emerging evidence has shown that pinocembrin protects myocardial ischemic injury (I/R)-induced cardiac fibrosis and arrhythmias in animals via its anti-inflammatory or antioxidant activities.

BACKGROUND Cardiac infarction frequently leads to arrhythmia and ischemia/reperfusion (I/R) aggravates cardiac injury. Pinocembrin can resist cerebral ischemia and decrease cardiac infarction area. This study thus generated a rat myocardial I/R model to assess the effect on ventricular rhythm and

Acute vascular- and neuroprotective effects of pinocembrin (1) were evaluated in a rat model of focal cerebral ischemia. Focal cerebral ischemia was induced by the middle cerebral artery occlusion (MCAO) for 24 h. 5,7-Dihydroxyflavanone (compound 1; at 3, 10, or 30 mg/kg), intravenously injected at

OBJECTIVE To investigate the relationship between cerebroprotection of pinocembrin and epoxyeicosatrienoic acids (EETs) and their regulating enzyme soluble epoxide hydrolase (sEH). METHODS Rats underwent middle cerebral artery occlusion (MCAO) to mimic permanent focal ischemia, and pinocembrin was

BACKGROUND Pinocembrin is a major flavonoid molecule isolated from honey and propolis. It has versatile pharmacological and biological activities including antimicrobial, anti-inflammatory, antioxidant, and anticancer activities as well as neuroprotective effects against cerebral ischemic injury.

The aim of this study was to investigate the effects of pinocembrin on brain ischemia/reperfusion (I/R) injury and the potential involvement of autophagy activity changes in the penumbra area in the mechanisms of pinocembrin activity. Focal cerebral I/R model was induced by middle cerebral artery

Tissue-type plasminogen activator (t-PA) remains the only approved therapy for acute ischemic stroke but has a restrictive treatment time window of 4.5 hr. Prolonged ischemia causes blood-brain barrier (BBB) damage and increases the incidence of hemorrhagic transformation (HT) secondary to

Pinocembrin is one of the flavonoids at the highest concentration in propolis. In this study, we investigated the neuroprotective effect of pinocembrin on ischemia/reperfusion and ischemia/reperfusion-like insults. Protection by pinocembrin was studied at the in vivo level using a model of middle

BACKGROUND Cerebral ischemia/reperfusion (I/R) injury is a common pathological process after cardiac arrest, shock and acute cerebral infarction recanalization, which causes serious injury in brain function. Pinocembrin (Pino), a natural flavonoid at the highest concentration in propolis, exhibited

Endoplasmic reticulum stress (ER stress) is known to play a vital role in mediating ischemic reperfusion damage in brain. Our previous studies showed that pinocembrin alleviated cerebral ischemic injury in ischemia/reperfusion and vascular dementia animal models, but whether attenuation of ER

BACKGROUND Bee propolis, a mixture of the secretion from bee tongue gland and wax gland, was collected from the tree bud and barked by bees. The components were rich in terpenes, phenolics, and flavonoids, and had anti-cancer, anti-bacterial, anti-inflammatory, hepatoprotective, and neuroprotection
