training, a young Serge Gauthier found himself up to his elbows in lecithin. His sleeves rolled up and his arms buried deep in big barrels of imported lecithin, he and his mentor, Dr. Pierre Etienne, scooped up kilos and kilos of the phospholipid like market merchants and handed it over to the families of patients with Alzheimer’s disease (AD). The two researchers hoped that with regular lecith...

Purpose: To investigate the physicochemical properties and DPPH radical scavenging activity of gallic acid–lecithin complex Methods: The complex of gallic acid with lecithin was prepared by solvent method. The physicochemical properties of the complex were investigated by ultraviolet-visible spectrometry (UV), infrared spectrometry (IR), scanning electron microscopy (SEM), differential scanning...

The initial rate of lecithin: cholesterol acyl transferase and serum concentration of lipids were determined in euthyroid, hypothyroid and hyperthyroid subjects. In hyperthyroid subjects, the serum levels of total and free cholesterol were significantly lower than in normal subjects and the fractional lecithin: cholesterol acyl transfer rate was significantly higher than in normal subjects. The...

We compared seven techniques, commonly used for detection of amniotic fluid phospholipids in thin-layer chromatography, with respect to their sensitivity to saturation of the fatty acid carbon-chain of lecithin. The techniques fell into two classes: sensitive and insensitive; those classed as saturation sensitive were less than or equal to 10% as sensitive to fully saturated lecithin as to leci...

Background: Egg yolk is the main cryoprotectant agent in semen freezing extenders which is used in order to protect spermatozoa against cold shock. However, elimination of animal bioproducts from the cryopreservation protocol is becoming mandatory. Therefore, the aim of this study is to compare a previously studied, homemade soya bean lecithin based extender with a commercially available extend...

1. We have studied the plasma lipoprotein abnormalities in obstructive jaundice to test the hypothesis that the abnormalities would correlate with plasma lecithin--cholesterol acyltransferase activity. 2. Very-low-density lipoproteins (VLDL) were normal in composition and had a normal pre-beta electrophoretic mobility when lecithin--cholesterol acyltransferase activity was high. When it was low...

In the course of W-tracer studies on the biological synthesis of lecithin in lung tissue slices, the ratio of fatty acid activity to glycerol activity in lecithin was higher than in the triglyceride fraction. It was suggested that the observed isotope distributions could be due to turnover of the fatty acid portion of lecithin without a corresponding synthesis and breakdown of the remainder of ...

Addition of arachidonic acid (AA) and docosahexaenoic acid (DHA) to infant formula promotes visual and neural development. This study was designed to determine whether the source of dietary long-chain polyunsaturated fatty acids (LCPUFA) affected overall animal health and safety. Piglets consumed ad libitum from 1 to 16 d of age a skim milk-based formula with different fat sources added to prov...

AIM The aim was to compare commercially available soybean milk-based extenders, viz. Bioxcell(®) and Optixcell(®) (IMV, France) with standard Tris-citrate-fructose-egg yolk-glycerol (TFYG) extender for cryopreservation of buffalo semen. MATERIALS AND METHODS Semen was collected twice a week in artificial vagina from six sexually mature, 4-6 years old, healthy breeding bulls of Surti buffalo b...

Forty isolates of endophytic bacteria isolated from banana tree roots were assessed as to their capacity to solubilize phosphate in a solid culture medium supplemented with different inorganic and one organic source of phosphorus. The amount of phosphorus (P) in each liquid medium was quantified, and an indirect assessment of acid phosphatase activity was performed. All assays had a fully rando...
