Iron-binding antioxidant capacity is impaired in diabetes mellitus.
TLDR
Iron-binding antioxidant capacity is decreased in diabetes mellitus and could not be explained by differences in Tf glycation, lipid, or inflammatory status and was not associated with higher non-transferrin-bound iron levels. Expand
Transferrin Modifications and Lipid Peroxidation: Implications in Diabetes Mellitus
TLDR
Results suggest that lower transferrin concentration and its glycation can, by enhancing the pro-oxidant effects of iron, contribute to the increased lipid peroxidation observed in diabetes. Expand
Structural features of the binding site of cholera toxin inferred from fluorescence measurements.
TLDR
The dependence on pH of the fluorescence of cholera toxin and its A and B subunits has been studied at 25 degrees C and indicates that the tryptophan fluorescence is only moderately altered by ionizable groups displaying a pKa in the range 4 to 9. Expand
Iron-induced oxidative stress in haemodialysis patients: a pilot study on the impact of diabetes
TLDR
In haemodialysis patients, higher lipid peroxidation is determined by higher body iron stores, which is accompanied by a loss in iron-binding antioxidant capacity and is more pronounced in diabetes mellitus. Expand
A novel method to quantify in vivo transferrin glycation: applications in diabetes mellitus.
TLDR
The results indicate that the adapted nitroblue tetrazolium assay combined with immunocomplexation of serum transferrin is suitable to detect differences in in vivo transferrin glycation between non-diabetic, type 1 and type 2 diabetic subjects. Expand
Identification of prenylcysteine carboxymethyltransferase in bovine adrenal chromaffin cells.
TLDR
Effector studies showed that the methyltransferase activity varied depending on the concentration and chemical nature of the cations present, while divalent metallic ions displayed diverging inhibitory effects. Expand
Subcellular structure of bovine thyroid gland. A study on bovine thyroid membranes by buoyant-density-gradient centrifugation in a B-XIV zonal rotor.
TLDR
A combined mitochondrial and light mitochondrial fraction and a microsomal fraction were isolated from bovine thyroid gland and fractionated further in a B-XIV zonal rotor, resulting in the formation of a single zone at intermediate densities (agg of membranes?). Expand
Phospholipases A1 and A2 in bovine thyroid.
TLDR
Enzyme assays performed on subcellular fractions suggest the soluble phospholipases to be of lysosomal origin and the solubilized phospholIPase A2 activity of homogenate sediment toBe of microsomal origin. Expand
The nuclear lipids of bovine hypertrophic thyroid.
TLDR
A highly purified preparation of bovine hypertrophie thyroid nuclei was isolated by means of an adapted method of Widnell, C. C. and Tata, J. R. (1964), followed by a centrifugation step in a zonal rotor. Expand
Subcellular structure of bovine thyroid gland. The localization of the peroxidase activity in bovine thyroid.
TLDR
A localization of guaiacol peroxidase in rough-endoplasmic-reticulum membranes (or in membranes related to them) seems very likely. Expand
