In this study, we investigated the cardioprotective effects of resveratrol. Rats were intraperitoneally administered with resveratrol (25 mg/kg bw) or vehicle (ethanol 10%) for 7 days and their heart subjected to ischemia/reperfusion injury. Isolated hearts were langendorff perfused, left ventricular functions as heart rate and developed pressure, as well as, heart antioxidant status were determined. Data showed that resveratrol improved recovery of post-ischemic ventricular functions when compared to control. Resveratrol also improved myocardial lipoperoxidation, free iron and antioxidant enzyme activities. Resveratrol decreased significantly catalase while it increased peroxidase and superoxide dismutase activities. In this later case, native PAGE analysis of superoxide dismutase isoforms revealed that resveratrol up regulated iron and manganese isoforms. Resveratrol exerted potential cardioprotection partly by its antioxidant properties.

Endometriosis, though not classified as a carcinogenic condition, shares features such as oxidative stress, migration, invasion, angiogenesis, and inflammation with tumor cells. This study aims to review the effects of flavonoids on these processes and their molecular mechanisms in preventing and treating endometriosis. A comprehensive review was conducted, involving a literature search in online databases using keywords like "endometriosis," "endometrioma," and "flavonoid.

Resveratrol is an important phytoalexin that adapts to and responds to stressful conditions and plays various roles in health and medical therapies. However, it is only found in a limited number of plant species in low concentrations, which hinders its development and utilization. Chalcone synthase (CHS) and stilbene synthase (STS) catalyze the same substrates to produce flavonoids and resveratrol, respectively.

Alzheimer's disease is a complicated, multifaceted, neurodegenerative illness that places an increasing strain on healthcare systems. Due to increasing malfunction and death of nerve cells, the person suffering from Alzheimer's disease (AD) slowly and steadily loses their memories, cognitive functions and even their personality. Although medications may temporarily enhance memory, there are currently no permanent therapies that can halt or cure this irreversible neurodegenerative process.

Aims: Postmenopausal women experience an increase in cardiovascular, sexual, and emotional changes that can significantly impact their quality of life. Although phytoestrogens offer therapeutic benefits, our understanding of resveratrol's effects remains limited. This study aims to evaluate the effects of using resveratrol on the lipid profile of postmenopausal women.

Blast lung injury (BLI) is a major cause of death in blast injuries, largely due to pulmonary edema. Effective clearance of alveolar fluid is critical for resolving pulmonary edema, with the epithelial sodium channel (ENaC) playing a key role in this process. Resveratrol (RES), a natural compound with known antioxidant and anti-inflammatory properties, has shown promise in treating respiratory diseases.
