the affinity of low density lipoprotein (ldl) to its receptor is very important, because most of ldl-uptake pathway is done by the ldl receptor and the change in size of ldl particle and the modification in its components may affects the ldl affinity for its receptor. in this study, the effects of lipophilic agents such as vitamin e and seven volatile oils: anethol, eugenol, geraniol, limonene,...

A commercial casein hydrolysate was microencapsulated in liposomes produced with non-purified soy lecithin, cryoprotected with two different disaccharides and lyophilized. The encapsulation efficiency of casein hydrolysate ranged from 30 to 40%. The powders were analyzed by differential scanning calorimetry (DSC), scanning electron micrography (SEM), infrared spectroscopy (FTIR) and wide angle ...

A major problem of current vaccines is storage stability, often requiring strict maintenance of cold chains. In the course of the eradication of smallpox, a freezedried vaccinia virus (Dryvax), which proved to be very stable, was used to overcome this limitation. However, Dryvax needs to be reconstituted before usage and is administered using a bifurcated needle, procedures that pose a number o...

Methanolic extract from lyophilized roots of Impatiens glandulifera Royle was analyzed by high performance liquid chromatography using DAD and FLD detection and this revealed one dominant highly fluorescent very unstable substance. The stability of this derivative is strongly dependent on the plant material drying procedure and extraction procedure used. The structure of the substance was estab...

the purification and identification of reduced antibody fraction by spectrophotometer method; mass of Anti-CEA and MDP; time and temperature of lyophilized method. The best conditions for lyophilized kits were selected and the labelling efficiency was determined using ascending paper chromatography on Whatman 3MM paper and TLC-SG in 0.9 % saline and methyl ethyl ketone as a solvent. This work b...
