Depletion of the antioxidant capacity of LDL is an early event in the oxidation process. The main antioxidant in LDL is a-tocopherol, with smaller quantities of 0-carotene and 7-tocopherol also present. The importance of antioxidants in inhibiting the oxidative modification of LDL is su ested by human and animal studies on the prevention of atherosclerosis. Preliminary reports... 

Routine antioxidant vitamin supplementation, e.g. with vitamins C and/or E, of the diabetic diet should be considered. Vitamin C depletion is present in all diabetics irrespective of the presence of vascular disease. A recent study demonstrated no significant difference between the dietary intake of vitamin C (the main determinant of plasma ascorbate) in patients with diabetes and age-matched controls, confirming the view that ascorbate depletion is secondary to the diabetic process and su esting that diabetic patients require additional intakes of the vitamin to maintain optimal levels (Sinclair et /., 1994). Antioxidant supplementation may have additive beneficial effects on a wide variety of processes involved in diabetic vascular damage including blood pressure, immune function, inflammatory reactions.

A discrete-event simulation tool considers - nomen est omen - discrete events at discrete points in time. Typically, in a discrete-event simulator items such as parts are moving through the modeled system changing their state, e.g., when they enter or leave a machine. A reactor in the process industry continuously produces a certain output. This is something a discrete-event simulator is not really made...

Ligation-Deligation Processes in Nickel-Reconstituted Heme Protejjns. In contrast with the 6-coordinate models, 5-coordinate sites of Hb and Mb show virtually no difference between the Raman spectra obtained with low and high powers for excitation at 420 nm. The undetectably low quantum yield for dissociation fo the nickel globins su ests that either (1) the dissociative state is not...

The EST has continued to be a popular test subject to further optimization, especially through the addition of alternative pathways of differentiation and the addition of molecular markers of effects. Besides cardiac muscle differentiation, other cell types such as neurons (29-31), osteoblasts (32), adipocytes (33), and hepato-cytes (34) have been generated in dedicated differentiation protocols, providing additional opportunities for testing the interference of differentiation pathways with chemical exposures. The addition of transcriptomics approaches to measure differential gene expression, both as influenced by the differentiation process as well as due to chemical exposure, has proven informative and may enhance the predictability of EST assays (35). The extension of this concept to human embryonic stem cell lines is still in its infancy, but has opened a new realm of options that bypasses the need for interspecies extrapolation (36).
