Gas- and particulate-phase specific tracer and toxic organic compounds in environmental tobacco smoke.
Chemosphere 61 , 1512-1522, (2005) Cigarette smoke constituents are worthy of concern and characterized as carcinogens. Different experiment conditions may affect the environmental tobacco smoke (ETS) constituents. A study was undertaken in a 75.5-m3 spare office to evaluate ETS constituents i... |

Oxysterols: modulators of cholesterol metabolism and other processes.
Physiol. Rev. 80 , 361-554, (2000) Oxygenated derivatives of cholesterol (oxysterols) present a remarkably diverse profile of biological activities, including effects on sphingolipid metabolism, platelet aggregation, apoptosis, and protein prenylation. The most notable oxysterol activities cen... |

Oxysterols as non-genomic regulators of cholesterol homeostasis.
Trends Endocrinol. Metab. 23 , 99-106, (2012) Tight regulation of cellular and plasma cholesterol is crucial to proper cellular functioning because excess free cholesterol is toxic to cells and is associated with atherosclerosis and heart disease. Cellular cholesterol homeostasis is regulated by enzymati... |

Docosahexaenoic acid supplementation fully restores fertility and spermatogenesis in male delta-6 desaturase-null mice.
J. Lipid Res. 51 , 360-367, (2010) Delta-6 desaturase-null mice ((-/-)) are unable to synthesize highly unsaturated fatty acids (HUFAs): arachidonic acid (AA), docosahexaenoic acid (DHA), and n6-docosapentaenoic acid (DPAn6). The (-/-) males exhibit infertility and arrest of spermatogenesis at... |

The Liebermann-Burchard reaction: sulfonation, desaturation, and rearrangment of cholesterol in acid.
Lipids 42 , 87-96, (2007) In the Liebermann-Burchard (LB) colorimetric assay, treatment of cholesterol with sulfuric acid, acetic anhydride, and acetic acid elicits a blue color. We studied the reactivity of cholesterol under LB conditions and provide definitive NMR characterization f... |

Normal-phase liquid chromatography-atmospheric-pressure photoionization-mass spectrometry analysis of cholesterol and phytosterol oxidation products.
J. Chromatogr. A. 1439 , 74-81, (2016) During thermal processing of sterols, complex mixtures of sterol oxidation products may be formed. Here, a new method for the separation and detection of such products is described. The method is based on normal-phase liquid chromatography (NPLC) for separati... |

Cholesterylene, a newly recognized tissue lipid, found at high levels in the cornea.
Biochem. Biophys. Res. Commun. 186(3) , 1647-55, (1992) In the course of measuring the concentration of cholesterol in an opacified dog cornea by gas-chromatography, relatively large amounts of an unidentified non-saponifiable lipid were recognized. When the unknown lipid was subjected to gas chromatographic-mass ... |
