Probiotic formulations containing lecithin phospholipids have been shown to extend their viability. However, the protective effect of and properties mixtures probiotic cells in aqueous media not fully documented. The aim this study was investigate interactions between Bifidobacterium animalis ssp. lactis (Bifido) probiotics lecithin. lecithin-Bifido were dependent on concentration. FTIR Raman s...

Sonicated unilamellar lipid vesicles, consisting of egg lecithin, stearylamine, and cholesterol in 7:2:1 molar ratios, promoted the aggregation of tobacco (Nicotiana glutinosa) protoplasts with the aid of mono- or divalent cations.A reaction mixture containing liposomes (0.4 micromoles lipid per milliliter), 50 millimolar CaCl(2), 0.5 molar mannitol, and 5 x 10(5) protoplasts per milliliter res...

Size-quantized CdS nanocrystals of controlled dimensions are synthesized within monodisperse egg lecithin vesicles made by detergent depletion. Cryo-transmission electron microscopy (cryo-TEM) enables imaging in situ both of the vesicle wall and of the encapsulated nanocrystal. Cryo-TEM images confirm that only one particle per vesicle forms and that nanocrystal diameter is determined by the nu...

23Na NMR studies of large unilamellar vesicles of egg lecithin in salt solutions are reported. A shift reagent, the dysprosium nitrilotriacetate ion Dy[N(CH2CO2)3]3-2 has been used to distinguish between 23Na+ inside and outside the vesicles. When both are present and the shift reagent is present on only one side, two clearly distinct resonances are observed. Creation of a Na+ concentration gra...

The entrapping of a plague capsular antigen into the liposomes, prepared by the "reverse phase" evaporating method, was investigated. Both the native antigen and the antigen modified by palmitoylchloride were used. The entrapping of the modified antigen into the liposomes was greater than that of the native one: 46.1 +/- 5.4% and 3.7 +/- 2.7%, respectively. The highest content of the antigen on...

The study evaluated the effect of two animal protein-free extenders on ram semen cryopreservation tropical hair breeds. ejaculates were collected from 8 rams (4 Blackbelly and 4 Pelibuey), which mixed (pooled) by breed, diluted cryopreserved in three different extenders: Animal protein [Tris egg yolk (Triladyl®)], AndroMed® (lecithin soy bean) OPTIXcell® (liposome). Sperm analyses total (TM) pr...
