1. Heterogeneidade e mecanismos moleculares da atividade anti-apoptótica das subfrações de HDL em células endoteliais humanas / Heterogeneity and molecular mechanisms of anti-apoptotic activity of high-density lipoprotein (HDL) subfractions on endothelial cells
Introdução: A lipoproteína de baixa densidade (LDL) e suas formas oxidadas (LDLox) possuem múltiplas propriedades aterogênicas, atuando na deposição de colesterol, indução e manutenção da inflamação, disfunção endotelial, surgimento de células espumosas na parede arterial e conseqüente formação da placa de ateroma. Adicionalmente, LDLox in

2. Presence of foam cells containing oxidised low density lipoprotein in the synovial membrane from patients with rheumatoid arthritis.
OBJECTIVE--Increased concentrations of lipid peroxidation products have been described in the serum and synovial fluid from patients with rheumatoid arthritis. A large proportion of the unsaturated lipids in human extracellular fluids is a component of low density lipoprotein (LDL). The oxidative modification of LDL, and its subsequent uptake by macrophages,

3. Extent of oxidative modification of low density lipoprotein determines the degree of cytotoxicity to human coronary artery cells.
OBJECTIVE--To assess whether the extent of LDL oxidation influences its cytotoxic effects, thus contributing to its atherogenic potential. DESIGN AND SETTING--The effects of native and modified LDL on cultured human coronary artery smooth muscle cells (SMC) and endothelial cells (ECs) were investigated. MAIN OUTCOME MEASURES--Four indices of cytotoxicity wer
