The relationship between antioxidants and endothelial cell injury was examined in 119 patients with (n = 48) or without (n = 71) vascular disease who were attending a hyperlipidaemia clinic. Serum levels of total antioxidant capacity, glutathione peroxidase (a protein antioxidant), von Willebrand factor (vWf, a specific endothelial cell product and marker of injury) and routine lipids were measured...
Over 100 motilin fragments and analogues, including monosubstituted C-terminal-deleted analogues, conformationally restricted analogues, analogues with peptide bond isoteres (CH 2 -NH), and N-terminal fragments adjunct to an amphiphilic helix, were synthesized by solid-phase methodology, purified by reverse-phase HPLC, and assayed in vitro in a muscle strip bioassay (rabbit duodenum) and in...
Menaquinone (MK) is a non-protein component of the Bacillus subtilis (Bs) electron transport chain synthesized from chorismate through a series of MK-specific reactions. The genes encoding biosynthesis of the naphthoquinone ring of MK are clustered at 273° on the Bs chromosome. A 3.9-kb region capable of rescuing men mutants blocked in the early stages of MK biosynthesis was sequenced and found...
