AGE RELATED LIPID OXIDATION IN HUMAN LENS MEMBRANES BY INFRARED SPECTROSCOPY. Borchman D. Department of Ophthalmology and Visual Sciences, University of Louisville, Louisville Kentucky, 40202, USA. To measure primaty and secondary products of lipid Purnose oxidation with age in human lens membranes. Lipid oxidation is believed to contribute to a number of senescent diseases including cataract. ...

coenzyme q10, a lipid soluble benzoquinone, has excellent antioxidant and membrane stabilizing properties in the cardiac tissue. the present study investigated the effects of coenzyme q10 on in vitro ldl oxidation quantitavely. the formation of conjugated dienes, malondialdehyde (mda) and electrophoretic mobility were monitored as markers of the oxidation of ldl, respectively. coenzyme q₁₀ show...

BACKGROUND Growth hormone (GH) stimulates whole-body lipid oxidation, but its regulation of muscle lipid oxidation is not clearly defined. Mice with a skeletal muscle-specific knockout of the GH receptor (mGHRKO model) are protected from high fat diet (HFD)-induced insulin resistance and display increased whole-body carbohydrate utilization. In this study we used the mGRHKO mice to investigate ...

Overweight is associated with abnormalities of lipid metabolism, many of which are reversed by exercise. We investigated the impact of experimental antilipolysis and acute exercise on lipid kinetics and oxidation from VLDL-TG, plasma FFA, and "residual lipids" in overweight men (n = 8) using VLDL-TG and palmitate tracers in combination with muscle biopsies in a randomized, placebo-controlled de...

one of the simplest methods for short-term handling and storage of fish is the refrigeration in combination with dip treatments. this study was conducted to determine the effect of pre-storage α-tocopherol acetate dipping treatments on lipid stability of refrigerated rainbow trout fillets. trout fillets were dipped in α-tocopherol acetate solutions (200 and 500 mg kg-1 flesh) and subsequently s...

The effects of a 7 d high-fructose diet (HFrD) or control diet on lipid metabolism were studied in a group of six healthy lean males. Plasma NEFA and beta-hydroxybutyrate concentrations, net lipid oxidation (indirect calorimetry) and exogenous lipid oxidation (13CO2 production) were monitored in basal conditions, after lipid loading (olive oil labelled with [13C]triolein) and during a standardi...

Acute physical exercise enhances insulin sensitivity in healthy subjects. We examined the effect of a 42-km marathon run on insulin sensitivity and lipid oxidation in 19 male runners. In the morning after the marathon run, basal serum free fatty acid concentration was 2.2-fold higher, muscle glycogen content 37% lower (P < 0.01), glycogen synthase fractional activity 56% greater (P < 0.01), and...

PURPOSE To quantify age-related changes in products of lipid oxidation in human lenses and to relate these changes to membrane hydrocarbon chain structure. Deviation from a well-defined membrane-lipid composition and structure could result in alterations in membrane function and disruption of the homeostasis of the cell. METHODS Infrared spectroscopy was used to detect lipid compositional and...

objective: the present study was performed to compare the antioxidant effect of two different doses of zinc on lipid oxidation in type 2 diabetic patients. materials and methods: this double-blind, randomized controlled trial was conducted on 60 type 2 diabetic patients in yazd diabetes research center in 2008. the subjects were randomly allocated to receive zinc sulfate (iran, alhavi) either 2...
