conclusions employing the lpe as a new approach, gives novel concept of probiotic-products in food and medical marketing. results results showed that, lpe had more antipathogenic effects, antioxidant activity, and stability during storage-time when compared to fresh probiotic-extract. objectives in this study extract of cultured probiotics without cells was evaluated for its antimicrobial effec...

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...

introduction: radiolabeled antibiotics are being used for the specific diagnosis of infection by exploiting their specific binding properties to the bacterial components, thereby making it possible to differentiate infection from sterile lesions. the aim of this work was to prepare and evaluate a freeze-dried kit of ciprofloxacin designed for the labeling with 99mtc. methods: factors like amou...

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...

To further improve analytical accuracy in clinical chemistry, proficiency testing needs amelioration in the quality of materials tested and in target value assignment. To obtain information on the actual state-of-the-art in the Lombardy region of Italy, and to examine the behavior of different types of control materials (fresh-frozen human sera and lyophilized materials), we developed the follo...
