BACKGROUND This study was conducted to evaluate the effects of consuming thermally oxidized oil supplemented with pectin on liver glutathione peroxidase activity, serum malondialdehyde and lipid profiles in male Sprague-Dawley rats. METHODS Fifty growing male Sprague-Dawley rats were randomly divided into different groups. The diets differed only in their fat and pectin content. The diets had...
Oxidized low density lipoprotein (LDL) and acetyl LDL are recognized by the scavenger receptor class A type I/II (SR-AI/II) on macrophages and liver endothelial cells. Several investigators have suggested that there are additional receptors specific for oxidized LDL, but characterization of these alternate receptors for oxidized LDL and evaluation of their quantitative importance in uptake of o...
This study was aimed to determine the acylglycerols composition, quality characteristics, and protective role of dietary pumpkin seed oil (PSO) in rabbits. PSO was thermally oxidized and analyzed for quality characteristics and acylglycerols composition using reversed phase high performance liquid chromatography with diode array detection (HPLC-DAD). Oxidized and un-oxidized oil samples were fe...
The relative toxicities of several lipid oxidation products formed on oxidized LDL, their presence on oxidized LDL, and potential mechanisms of cell injury compared to oxidized LDL were examined. Toxicities to fibroblasts, with lipoprotein-deficient serum supplementation, were: 7 beta-hydroperoxycholesterol > 7 beta-hydroxycholesterol = 4-hydroxynonenal > 7-ketocholesterol > 5 alpha, 6 alpha-ep...
We have recently demonstrated that the platelet low-density lipoprotein (LDL) receptor is immunologically different from the "classic" receptor of nucleated cells. We undertook the current studies to investigate the interaction of this receptor with oxidized LDL and to determine whether an endocytosis-mediated response is involved in the binding of LDL to platelets. The platelet LDL receptor re...
BACKGROUND AND OBJECTIVES Oxidized HDL (oxHDL) may behave as proinflammatory HDL because of reduced anti-inflammatory capacity and is considered a risk factor for mortality in patients on maintenance hemodialysis (MHD). The study presented here assessed the effect of oxHDL on protein-energy wasting (PEW) in MHD patients. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS This prospective study exa...
Nitidon, a highly oxidised pyranone derivative produced by the basidiomycete Junghuhnia nitida, has been isolated and its biological activities evaluated. The structure was determined by spectroscopic methods. Nitidon exhibits antibiotic and cytotoxic activities and induces morphological and physiological differentiation of tumor cells at nanomolar concentrations.
BACKGROUND Oxidized Lp(a) [ox-Lp(a)] has been reported to play more potent roles than native Lp(a) in atherosclerosis. We investigated the distribution characteristics of plasma ox-Lp(a) and Lp(a) immune complex [Lp(a)-IC] levels in newborns and children. METHODS Plasma ox-Lp(a) and Lp(a)-IC levels were measured in 747 children and 30 cord blood by ELISAs. RESULTS The mean levels of Lp(a), ...
BACKGROUND The purpose of this retrospective study was to identify an appropriate material that can be used as a covering for patients with a spontaneous pneumothorax (SP). A total of 279 patients were studied over a period of eight years. METHODS The patient characteristics, surgical details and perioperative outcomes were analyzed. We compared the clinicopathological characteristics between...
The oxidative modification of low-density lipoprotein (LDL) has been implicated as a pro-atherogenic process in the pathogenesis of atherosclerosis. Macrophages rapidly take up oxidized LDL via scavenger-receptor-mediated pathways and thereby develop into lipid-laden foam cells. The uptake mechanism has been studied extensively and several types of scavenger receptors have been identified. In c...
