Hypovitaminosis C and vitamin C deficiency in critically ill patients despite recommended enteral and parenteral intakes
TL;DR: Septic shock patients have significantly depleted vitamin C levels compared with non-septic patients, likely resulting from increased metabolism due to the enhanced inflammatory response observed in septic shock.
Journal ArticleDOI
Chromatographic quantitation of plasma and erythrocyte pentosidine in diabetic and uremic subjects.
TL;DR: Plasma pentosidine may be a useful marker for monitoring the biochemical efficacy of trials with aminoguanidine or other treatment modalities and may act as a signal for advanced glycosylation end product-mediated receptor uptake by macrophages and other cells and contribute to accelerated atherosclerosis in diabetes and uremia.

Vitamin C Improves Endothelium-Dependent Vasodilation in Patients With Insulin-Dependent Diabetes Mellitus
Farris K. Timimi,Henry H. Ting,Elizabeth A. Haley,Mary Anne Roddy,Peter Ganz,Mark A. Creager +5 more
TL;DR: Vitamin C selectively restores the impaired endothelium-dependent vasodilation in the forearm resistance vessels of patients with insulin-dependent diabetes mellitus, and indicates that nitric oxide degradation by oxygen-derived free radicals contributes to abnormal vascular reactivity in humans with Diabetes mellitus.

Food consumption and the incidence of type II diabetes mellitus
TL;DR: Prevention of type II diabetes might be aided by consumption of certain foods that are rich in nutrients with hypothesized health benefits, including green vegetables, fruit and berries, oil and margarine, and poultry.

TL;DR: Ascorbic acid supplementation at a dose of 500 mg per day for a brief period of 15 days resulted in an increase in the plasma ascorbate level temporarily, but it did not lower the blood glucose level of the diabetic patients.

Synthesis and some major functions of vitamin C in animals.
TL;DR: Using the in vitro method, the ascorbic acid synthesizing abilities of different species of animals in the phylogenetic tree are examined, and the results are given below.

The determination of diketo l-gulonic acid, dehydro-l-ascorbic acid, and l-ascorbic acid in the same tissue extract by the 2, 4-dinitrophenylhydrazine method.
TL;DR: Methods for determinations of vitamin C dehydro-Z-ascorbic (DHA), DHA, and DKA in the presence of each other are reported, indicating that these derivatives are identical substances.
Journal ArticleDOI
The use of homocysteine in the estimation of dehydroascorbic acid.
TL;DR: An account is given of a new method, based on the two findings that homocysteine rapidly reduces dehydroascorbic acid at pH 7 0, and that under certain simple conditions 2:6-dichlorophenolindophenol can be used to estimate ascorbic acid in the presence of homocy steine without interference from the latter compound.
