High plasminogen activator inhibitor (PAI)-1 levels and poor dietary fat quality are potential risk factors for cardiovascular disease. The aim was to investigate the cross-sectional associations between PAI-1 activity and dietary nutrient intake, focusing on fat quality, in a population-based study of 871 men aged 70 years. The relationship between PAI-1 and the fatty acid composition in serum...

Recently in PNAS, Hoshi et al. (1) report the results of elegant studies defining the molecular basis for the blood pressure-lowering effect of omega-3 fatty acids, in particular docosahexaenoic acid (DHA). They found that DHA, when infused intravenously, activated the large-conductance Caand voltage-activated K (BK) channels in vascular smooth muscle but that the infusion of DHA ethyl esters (...

Mechanisms of decreased cholesterol absorption mediated by phytosterols in the intestinal lumen" (2011). Phytosterols and their fatty acyl esters have been known for decades to lower LDL cholesterol, making them powerful nutraceuticals in lowering cardiovascular disease risk. The mechanisms by which phytosterols lower cholesterol, though, have been incompletely characterized. Three studies were...

S U M M A R Y The addition of cerebroside preparations to synthetic diets fed to rats caused an increased excretion of sterol in the feces as measured by the Liebermann-Burchard reaction. The mixed fatty acid esters obtained by hydrolyzing the cerebrosides had a similar but less marked effect. Both cerebrosides and fatty acid esters increased the concentration of Liebermann-Burchardpositive ste...

The composition and distribution of steryl esters in human diseased or developing brain tissue has been studied. The abnormal brain conditions included sudanophilic leukodystrophy, multiple sclerosis plaque, subacute sclerosing panencephalitis, and an old cerebral infarction and two types of brain-derived tumors. In addition to the above abnormal tissue, steryl esters were also examined in deve...

Gas-liquid chromatographic analysis of fatty acid methyl esters obtained from clinical isolates of Aeromonas hydrophila, A. sobria, and A. caviae revealed the presence of two hydroxy fatty acid species, 3-OH 12:0 and 3-OH 14:0.

VAHOUNY, GEORGE V. AND C. R. TREADWELL. Absorption oj cholesterol esters in the lymph-fistula rat. Am. J. Physiol. 195(z): 516520. rg#.-Free and esterified cholesterol fractions in thoracic duct lymph of rats were determined after the administration of emulsions containing saline, albumin, taurocholate, oleic acid and free cholesterol, or fatty acid esters of cholesterol. Total lymph cholestero...

This review is concerned with lipase catalyzed synthesis of sugar fatty acid esters in water immiscible organic solvents. Sugar esters are widely used nonionic and nontoxic biosurfactants. Certain sugar esters inhibit microbial growth and have other activities. Lipase mediated synthesis has important advantages over conventional chemical synthesis of sugar esters. Lipase catalyzed synthesis is ...

Phloridzin (phlorizin or phloretin 2'-O-glucoside) is known for blocking intestinal glucose absorption. We have investigated the anticarcinogenic effect of phloridzin and its novel derivatives using human cancer cell lines. We have synthesised novel acylated derivatives of phloridzin with six different long chain fatty acids by regioselective enzymatic acylation using Candida Antarctica lipase ...

SUMMAR,Y Incubation of human serum solutions low in glyceride content for 16 hr resulted in a net increase of cholesterol esters in all three major human serum lipoprotein classes, namely the very low-density lipoproteins of d < 1.006 (VLDL), low-density lipoproteins of d 1.006-1.063 (LDL) and highdensity lipoproteins of d 1.063-1.21 (HDL). Transfer of glycerides from the VLDL to the LDL and HD...
