OBJECTIVE Chronic low-grade inflammation in obesity is characterized by macrophage accumulation in white adipose tissue and adipokine production deregulation. Obesity also is characterized by oxidative stress related to inflammatory signaling. The aim of this study was to analyze whether dietary supplementation with a rice bran enzymatic extract (RBEE),(More)
The aim of the present study was to evaluate the vascular effects of an enzymatic extract of grape pomace (GP-EE) on isolated arteries, focusing our attention on endothelium-derived relaxation and on its antioxidant properties. Grape pomace derived from wine making was extracted by an enzymatic process and its composition of polyphenols was evaluated by(More)
BACKGROUND AND PURPOSE Rice bran enzymatic extract (RBEE) has advantages compared to the original rice bran or its oils including water solubility, lack of rancidity and increased content in high nutritional proteins and nutraceutical compounds, particularly phytosterols, γ-oryzanol and tocols. Our aim was to determine the beneficial effects of RBEE in the(More)
Acetyl-L-carnitine (ALC) and propionyl-L-carnitine (PLC) are two naturally occurring carnitine derivates formed by carnitine acetyltransferase. The beneficial cardiovascular effects of ALC and PLC have been extensively evaluated in animals and humans during the last 20 years. For instance, many clinical trials have suggested ALC and PLC as potential(More)
BACKGROUND Rice bran enzymatic extract (RBEE) used in this study has shown beneficial activities against dyslipidemia, hyperinsulinemia and hypertension. Our aim was to investigate the effects of a diet supplemented with RBEE in vascular impairment developed in obese Zucker rats and to evaluate the main mechanisms mediating this action. METHODS AND(More)
BACKGROUND The inflammatory process associated with obesity mainly arises from white adipose tissue (WAT) alterations. In the last few years, nutritional-based strategies have been positioned as promising alternatives to pharmacological approaches against these pathologies. Our aim was to determine the potential of a rice bran enzymatic extract(More)
Propionyl-L-carnitine (PLC) is a naturally occurring derivative of carnitine that plays an important role in the metabolism of both carbohydrates and lipids, leading to an increase of ATP generation. PLC, however, is not only a metabolic drug; it is also a potent antiradical agent and thus may protect tissues from oxidative damage. PLC has been demonstrated(More)
BACKGROUND AND AIM Nutritional-based approaches aimed to prevent microvascular dysfunction associated to obesity present potential advantages over pharmacological strategies. Our aim was to test whether a rice bran enzymatic extract (RBEE)-supplemented diet could attenuate microvascular alterations in obese rats. METHODS AND RESULTS Lean and obese Zucker(More)
