We sought to determine if lecithin would produce a dose-response effect, increasing carotenoid bioaccessibility and Caco-2 cell uptake. A mixture of β-carotene, lycopene, lutein zeaxanthin was digested with concentrations (0–10 mg lecithin/mL test meal) ∼4% vegetable oil (n = 6 per condition). In vitro gastric, duodenal, jejunal digestion mimicked for 1 h each, the micellar fraction isolated an...

The objective of this study was to specify the effects of centrifugation and different surface of soybean lecithin-based extender on post-thaw Sperm quality of Ghezel ram semen. Semen samples were gathered from 5 mature Ghezel ram two/week for 3 weeks. After initial evaluation, the approved semen samples were pooled together and split into equal parts in Falcon tubes. Three samples were combine...

Although the serodiagnosis of syphilis by various tests has been carried out routinely for many years, our knowledge concerning the chemical nature of the specific antibody and antigen is still too limited to allow a satisfactory interpretation of the serological reactions involved. Valuable contributions towards the elucidation of the structure of several constituents of the antigen have been ...

We determined the distribution of lecithin molecular species between vesicles and mixed micelles in cholesterol super-saturated model biles (molar taurocholate-lecithin-cholesterol ratio 67:23:10, 3 g/dl, 0.15 M NaCl, pH approximately 6-7) that contained equimolar synthetic lecithin mixtures or egg yolk or soybean lecithins. After apparent equilibration (48 h), biles were fractionated by Supero...

Cholesterol and dietary phospholipids are important to the growth and survival of crustaceans. Soy lecithin enhances cholesterol solubilization while phosphatidylcholine transfers cholesterol from the hepatopancreas to the hemolymph. To study the influence of dietary lecithin on digestibility and transport of cholesterol to the hemolymph in Artemesia longinaris, diets with different levels of s...

IT has been reported in a previous communication [Spiegel-Adolf, 1932, 1] that, contrary to the Hofmeister series, colloidal solutions of egg-lecithin show a greater decrease in viscosityon addition of bromides than on addition of chlorides, iodides and thiocyanates. These results combined with more recent interferometric studies [Spiegel-Adolf, 1932, 2] were explained as due to reaction of mol...

The main objective of this work was to increase the retarding effect of the acid dye Telon(®) Blue RR (C.I. Acid Blue 62; DyStar, Frankfurt, Germany) release on polyamide fibres dyeing by encapsulation of the dye in liposomes as an alternative to synthetic auxiliaries, in order to reduce effluent pollution. The retarding effect achieved with the use of mixed cationic liposomes of dioctadecyldim...
