BACKGROUND: The first step in atherosclerosis formation is the ingurgitation of an oxidized low-density lipid (LDL) molecule by a macrophage which then turns into a foam cell within the vascular wall and initiates a cascade of inflammatory responses. Could it be that the potential cardioprotective effect observed in women receiving hormone replacement therapy (HRT) is modulated by estrogen's capacity to decrease LDL oxidation in the vascular wall and thus decrease atherosclerotic foam cells? MATERIALS AND METHODS: Thirty-four adult female Wistar rats were divided into three groups...

BACKGROUND: Familial hypercholesterolaemia (FH) leads to premature coronary artery diseases (CAD) which pathophysiologically can be measured by inflammation, endothelial activation and oxidative stress status. However, the status of these biomarkers among related unaffected relatives of FH cases and whether FH is an independent predictor of these biomarkers have not been well established. Thus, this study aims to (1) compare the biomarkers of inflammation, endothelial activation and oxidative stress between patients with FH, their related unaffected relatives (RUC) and normolipaemic subjects (NC) (2)determine whether FH is an independent predictor of these biomarkers...

Mild traumatic brain injury (TBI) accounts for the vast majority of the nearly two million brain injuries suffered in the United States each year. Mild TBI is commonly classified as complicated (radiographic evidence of intracranial injury) or uncomplicated (radiographically negative). Such a distinction is important because it helps to determine the need for further neuroimaging, potential admission, or neurosurgical intervention. Unfortunately, imaging modalities such as computed tomography (CT) and magnetic resonance imaging (MRI) are costly and not without some risk...

BACKGROUND AND AIMS: Elevated levels of lipoprotein(a) [Lp(a)] and oxidized phospholipids on apolipoprotein B-100 (OxPL-apoB) predict the progression of pre-existing mild-to-moderate calcific aortic valve stenosis (CAVS). Whether indirect markers of oxidation-specific epitopes (OSE) are also predictive is not known. The association between IgG and IgM autoantibodies and malondialdehyde-modified low density lipoprotein (MDA-LDL) and IgG and IgM apolipoprotein B immune complexes (apoB-IC), and the hemodynamic progression rate of CAVS was determined in the ASTRONOMER (Aortic Stenosis Progression Observation: Measuring Effects of Rosuvastatin, NCT00800800) trial...
