Analysis of the various lipids in amniotic fluid by multisample semiautomated quantitative high-performance thin-layer chromatography (HPTLC) is presented. Amniotic fluid (AF) lipids are extracted by liquid-liquid partition with chloroform-methanol (C-M) (final C-M-AF ratio of 4:2:1, v/v), 4-microliters aliquots of the

Statins inhibit endogenous cholesterol synthesis, up-regulate low-density lipoprotein (LDL) receptor expression in mammalian liver cells, and thus decrease circulating LDL-cholesterol concentrations. As cholesterol seems to play a role in the development of neurodegenerative diseases, it is of interest to evaluate

We aimed to assess the oxidant/antioxidant status within the ex vivo human coronary endarterectomy samples. To achieve this, we measured products of lipid oxidation (malondialdehyde, 7-ketocholesterol), lipids (cholesterol, cholesteryl esters) and vitamin E in endarterectomy samples. Content of malondialdehyde in
