Home use of vegetable oils, markers of systemic inflammation, and endothelial dysfunction among women.

29 Sep 2008 BACKGROUND: Most knowledge about adverse health effects of trans fats was mainly derived from studies done in Western populations of European or American origins; few data are available in the understudied region of the Middle East. OBJECTIVE: We ... Read more...

Foam-stabilizing effects and cling formation patterns of iso-alpha-acids and reduced iso-alpha-acids in lager beer.

25 Aug 2008 Foam-stabilizing properties and cling formation patterns of iso-alpha-acids and reduced iso-alpha-acids were investigated using an unhopped lager beer. Unhopped beer was dosed with iso-alpha-acid (Iso), rho-iso-alpha-acid (Rho), ... Read more...

A general, iterative, and modular approach toward carbohydrate libraries based on ruthenium-catalyzed oxidative cyclizations.

14 Aug 2008 Carbohydrates are an omnipresent class of highly oxygenated natural products. Due to their wide spectra of biological activities, they have been in the center of synthetic organic chemistry for more than 130 years. During the past 50 years ... Read more...
