Resveratrol and quercetin, widely found in foods and vegetables, are plant polyphenols reported to have a wide range of biological activities. Despite their limited bioavailabilities, both resveratrol and quercetin are known to exhibit anti-inflammation and anti-obesity effects. We hypothesized that gut microbiota may be a potential target for resveratrol and quercetin to prevent the development of obesity. The aim of this research was to confirm whether a combination of quercetin and resveratrol (CQR) could restore the gut microbiota dysbiosis induced by a high-fat diet (HFD)...

BACKGROUND AND OBJECTIVE: Atherosclerosis is characterized by a chronic low-grade inflammatory process which can result in atherothrombosis and a number of cardiovascular diseases (CVD). It is believed to be caused by multiple processes that involve inflammation and immunity. Mediterranean Diet (MedD) has been discovered to possess anti-inflammatory properties and associated with a reduction in the CVD risk and mortality. Its main component, extra-virgin olive oil (EVOO), is believed to be largely responsible for these effects and therefore, has been investigated in various studies...

Early embryonic loss and adverse birth outcomes are the major reproductive disorders that affect both human and animals. The LPS induces inflammation by interacting with robust cellular mechanism which was considered as a plethora of numerous reproductive disorders such as fetal resorption, preterm birth, teratogenicity, intrauterine growth restriction, abortion, neural tube defects, fetal demise, and skeletal development retardation. LPS-triggered overproduction of free radicals leads to oxidative stress which mediates inflammation via stimulation of NF-κB and PPARγ transcription factors...

PURPOSE: Cranberries are a rich source of polyphenolic antioxidants. Purified sugars or artificial sweeteners are being added to cranberry-based food products to mask tartness. Refined sugar and artificial sweeteners intake modulate gut microbiota and result in metabolic complications. We evaluated effects of isomalto-oligosaccharides (IMOs; sweet tasting non-digestible oligosaccharides) with cranberry extract (CRX) on high fat diet (HFD)-induced metabolic alterations in mice. METHODS: Male Swiss albino mice were fed normal chow or HFD (58% fat kcal), and were administered either CRX (200 mg/kg) alone or in combination with IMOs (1 g/kg)...

BACKGROUND: Coronary artery disease (CAD) is a disease progressing over many years. Genetic factors, as well as the exposure to risk factors, are continuously leading to endothelial dysfunction, vascular alterations and, eventually, organ damage, major cardiovascular events and deaths. Oxidative stress, platelet hyperactivity and low-grade inflammation are important modulators in this context, contributing to plaque formation. Since platelet activation plays a critical role in the development and progression of atherothrombotic events, the inhibition of platelet hyperactivity may contribute to decreased atherothrombotic risk...

Arachidin-1 [trans-4-(3-methyl-1-butenyl)-3,5,3',4'-tetrahydroxystilbene] is a polyphenol produced by peanut kernels during germination. The aim of the present study was to investigate the mechanism underlying the anti-inflammatory effect of arachidin-1 in endothelial cells (ECs). The results of cell adhesion and western blotting assays demonstrated that arachidin-1 attenuated tumor necrosis factor (TNF)-α-induced monocyte/EC adhesion and intercellular adhesion molecule-1 (ICAM-1) expression. Arachidin-1 was demonstrated to exert its inhibitory effects by the attenuation of TNF-α-induced nuclear factor-κB (NF-κB) nuclear translocation and inhibitor of κB-α (IκBα) degradation...

Breast cancer is one of the most common neoplasms worldwide, and in spite of clinical and pharmacological advances, it is still a clinical problem, causing morbidity and mortality. On the one hand, breast cancer shares with other neoplasms some molecular signatures such as an imbalanced redox state, cell cycle alterations, increased proliferation and an inflammatory status. On the other hand, breast cancer shows differential molecular subtypes that determine its prognosis and treatment. These are characterized mainly by hormone receptors especially estrogen receptors (ERs) and epidermal growth factor receptor 2 (HER2)...

Obesity is associated with non-alcoholic steatohepatitis (NASH) and hepatocellular carcinoma (HCC). Obesity and metabolic abnormalities resulting in low-grade inflammation can increase the risk of developing NASH and HCC. NASH, a risk factor for HCC, is characterized by increased inflammation, lipid accumulation, and liver injury. Obesogenic proteins modulate signaling pathways that induce physiological changes including lipogenesis, ROS, and inflammation. Silibinin, a polyphenol in milk thistle seed, has been shown to have anti-inflammatory properties...
