(–)-Epicatechin mediates beneficial effects of flavanol-rich cocoa on vascular function in humans

TL;DR: The data demonstrate that the human ingestion of the flavanol (-)-epicatechin is, at least in part, causally linked to the reported vascular effects observed after the consumption of flavanol-rich cocoa.
Journal ArticleDOI

Copper, oxidative stress, and human health.

TL;DR: The role of Cu in the oxidative defense system will receive special attention given that oxidative stress is a characteristic of Cu deficiency, and the potential biochemical lesions that might underlie these pathologies are reviewed.
Journal ArticleDOI

Procyanidin dimer B2 [epicatechin-(4β-8)-epicatechin] in human plasma after the consumption of a flavanol-rich cocoa

TL;DR: Dimmer procyanidin dimer, (-)-epicatechin, and (+)-catechin were detected in the plasma of human subjects as early as 30 min after the consumption of a flavanol-rich food such as cocoa.
Journal ArticleDOI

Probiotics and immunity

TL;DR: Promising results have been obtained with probiotics in the treatment of human inflammatory diseases of the intestine and in the prevention and treatment of atopic eczema in neonates and infants, however, the findings are too variable to allow firm conclusions as to the effectiveness of specific Probiotics in these conditions.
Journal ArticleDOI

Mushrooms, tumors, and immunity.

TL;DR: The antitumor mechanisms of several species of whole mushrooms as well as of polysaccharides isolated from Lentinus edodes, Schizophyllum commune, Grifola frondosa, and Sclerotinia sclerotiorum are mediated largely by T cells and macrophages, and the means by which they modulate the immune system and potentially exert tumor-inhibitory effects are reviewed.
