e"> In order to study the effective factors on the quality and quantity of lecithin extracted from soybean oil and the residual amount of phosphatids in degummed oil, this study <span style="font-size:...

There are still concerns over sperm quality when plant-based diluents used instead of animal-based semen extenders. Therefore, in our study we compared the effects one soybean lecithin-based (AndroMed®) and two egg yolk-based (BullXcell® Optidyl®) commercially available extenders on post-thaw vitro quality. Fifty ejaculates collected from ten bulls were aliquoted into three parts diluted with a...

OBJECTIVES Lecithin is a polyunsaturated phosphatidylcholine (PPC), which are high energy functional and structural elements of all biologic membranes. PPC play a rate-limiting role in the activation of numerous membrane-located enzymes, including superoxide dismutase and glutathione, which are important antioxidants protecting cell membranes from damage by reactive oxygen species (ROS). ROS-in...

Background: Trehalose, a non-permeable disaccharide, has a protective role related both to osmotic effect and specific interactions with membrane phospholipids, rendering hypertonic media, causing cellular osmotic dehydration before freezing, and then decreasing the amount of cell injury by ice crystallization. Within this study, an attempt was made to evaluation of two levels of 50 and 100 mM ...

Polyphenol-rich grape seed extract (0.1 w/w%) was incorporated in liposomes (1 w/w% soy lecithin) by high pressure homogenization (22,500 psi) and coated with chitosan (0.1 w/w%). Primary liposomes and chitosan-coated secondary liposomes containing grape seed extract showed good physical stability during 98 days of storage. Most of the polyphenols were incorporated in the shell of the liposomes...

Lecithin, a naturally small molecular surfactant, which is widely used in the food industry, can delay aging, enhance memory, prevent and treat diabetes. The interaction between zein and soy lecithin with different mass ratios (20:1, 10:1, 5:1, 3:1, 2:1, 1:1 and 1:2) in ethanol-water solution and characterisation of zein and lecithin composite colloidal nanoparticles prepared by antisolvent co-...

Developments in nanotechnology and in the formulation of liposomal systems provide the opportunity for cosmetic dermatology to design novel delivery systems. Determination of their physico-chemical parameters has importance when developing a nano-delivery system. The present study highlights some technological aspects/characteristics of liposomes formulated from egg or soy lecithins for topical...
