Journal ArticleDOI
(–)-Epicatechin mediates beneficial effects of flavanol-rich cocoa on vascular function in humans
Hagen Schroeter,Christian Heiss,Christian Heiss,Jan Balzer,Petra Kleinbongard,Carl L. Keen,Norman K. Hollenberg,Helmut Sies,Catherine Kwik-Uribe,Harold H. Schmitz,Malte Kelm +10 more
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.
Janet Y. Uriu-Adams,Carl L. Keen +1 more
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
Roberta R. Holt,Sheryl A. Lazarus,M. Cameron Sullards,Qin Yan Zhu,Derek D. Schramm,John F. Hammerstone,Cesar G. Fraga,Harold H. Schmitz,Carl L. Keen +8 more
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
Andrea T. Borchers,Carlo Selmi,Carlo Selmi,Frederick J. Meyers,Carl L. Keen,M. Eric Gershwin +5 more
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.
