BACKGROUND Small HDL particles have emerged as significant predictors of incident type 2 diabetes mellitus (T2DM) in adults with impaired glucose tolerance (IGT). However, no previous study has investigated HDL size in pediatric subjects with these clinical conditions. METHODS We studied the HDL size distribution by native polyacrilamide gradient gel(More)
Abnormal levels of plasma high-density lipoproteins (HDL) commonly reflect altered metabolism of the major HDL-apolipoprotein A-I (apo A-I). It is well known that thyroid hormones are involved in the regulation of lipoprotein metabolism, inducing significant changes in the concentration, size, and composition of plasma HDL. The purpose of this study was to(More)
High-density lipoproteins (HDL) includes a heterogeneous class of lipoproteins grouped into various subclasses that seem to have different antiatherogenic function. Cholesteryl ester transfer protein (CETP) and lecithin cholesterol acyltransferase (LCAT) play an active role in HDL remodeling. This study was designed to define the role of CETP and LCAT(More)
Takayasu's arteritis (TA) is a chronic inflammatory arteritis of unknown etiology involving mainly the aorta and its major branches. The interleukin (IL) 1β and IL-1 receptor antagonist have been playing an important role as regulators of inflammation. We investigated whether the polymorphisms at the IL-1B and IL-1RN gene cluster were associated with the(More)
BACKGROUND Takayasu's arteritis (TA) is a chronic inflammatory disease affecting the large arteries and their branches; its etiology is still unknown. In individuals suffering from TA, arterial inflammation progresses to stenosis and/or occlusion, leading to organ damage and affecting survival. Relation of TA with Mycobacterium tuberculosis has been known,(More)
AIMS Hypertension is a risk factor for atherothrombotic vascular events. Angiotensin II (Ang II), one of the main vasoactive hormones of the renin-angiotensin system, has been associated with the development and progression of atherosclerosis. However, it is not fully known how Ang II contributes to lipid-enriched atherosclerotic lesion formation. In human(More)
BACKGROUND Placental oxidative stress has been involved in the pathogenesis of certain reproductive adverse effects, including miscarriage. Paraxonase 1 (PON1) is a high-density lipoprotein(HDL)-linked enzyme that prevents oxidation of low-density lipoproteins (LDL) and is involved in detoxification from organophosphate pesticides. OBJECTIVE To assess the(More)
Dehydroepiandrosterone (DHEA) has a protective role against atherosclerosis, most likely mediating an anti-inflammatory action. In order to understand the mechanisms involved in this protection, we evaluated the effects of DHEA on several molecules involved in the inflammatory response. Reactive oxygen species (ROS), expression of adhesion molecules,(More)
Chronic hypothyroidism is frequently associated with atherosclerosis due to increased cholesterol plasma levels; nevertheless, the contribution of impaired reverse cholesterol transport (RCT) in this process has not been completely elucidated. The aim of this study was to evaluate the effect of thyroidectomy (Htx) upon the main stages of RCT in rats. Plasma(More)
BACKGROUND Apolipoprotein E polymorphisms have important effects on plasma lipid levels and in the genetic susceptibility to development of cardiovascular diseases. Thus, the purpose of this study was to investigate the association of apolipoprotein E polymorphisms with coronary artery disease and with plasma lipid levels in a group of Mexican Mestizo(More)
