This paper briefly reviews research on passive in situ samplers for aquatic environments but focuses on the development and application of the triolein-containing semipermeable membrane device in aquatic environmental monitoring. Special attention is paid to the calibration of the devices, quality control issues, and its potential uses in environmental assessments of aquatic contaminants. Also,...

Lipase-modified pH-responsive poly(N-isopropylacrylamide)-based microgels were synthesized. An optical device was subsequently fabricated by sandwiching the enzyme loaded responsive microgels between two thin Au layers, and their response to triolein, a model triglyceride, was investigated. The device's response depended on the triglyceride concentration, demonstrating its potential application...

Eyelids and conjunctivae of 36 normal individuals and 60 patients from six clinical groups of chronic blepharitis were cultured for aerobic and anaerobic bacteria. The most common species isolated were coagulase-negative staphylococci (C-NS) and Propionibacterium acnes. All strains of these species, and all Staphylococcus aureus strains isolated were tested for the ability to break down triglyc...

The effects of native and oxidized chylomicron remnants on the synthesis of cholesteryl ester and triacylglycerol in macrophages, and the way that this is influenced by exposure of the cells to oestrogen, was investigated using the human monocyte cell line THP-1 and chylomicron-remnant-like particles containing human apolipoprotein E (CRLPs). Synthesis of the lipids was measured by the incorpor...

INTRODUCTION: Embolization of fat from fractured long bones, pelvis and soft tissues occurs in 90% of major trauma cases1 and can be a major cause of morbidity and mortality. Fat Embolism Syndrome (FES), a serious manifestation of fat embolization, occurs in up to 10% of these cases and includes hypoxia, petechiae and mental disturbances. The mortality rate of FES has been reported to range fro...

The syntheses of triglyceride and its precursors were increased when liver homogenates of ketotic diabetic rats were incubated with [U-14C]-glycero 3-phosphate and cofactors. Triolein sonicates produced a concentration-dependent inhibition of the synthesis of both diglyceride and triglyceride, whereas monoolein sonicates had no effect. Rat serum very low density lipoproteins, like triolein soni...

The three-dimensional structure of lipase II of Geotrichum candidum strain ATCC34614 (GCL II) has provided insights with respect to the nature of the catalytic machinery of lipases. To support these structural observations, we have carried out an analysis of GCL II by mutagenesis. The gene encoding lipase II of Geotrichum candidum strain ATCC34614 (GCL II) was amplified using the polymerase cha...

Adult male rats were fed a semi-purified diet containing 20 p. 100 of lard or homogeneous triglycerides (tripalmitin, tristearin, triolein, trierucin) for 4 months. The rates of the processes (absorption, synthesis, degradation into bile acids, fecal and urinary excretion) involved in cholesterol turnover were measured using the isotope equilibrium method. The absorption coefficient of dietary ...
