OBJECTIVE To assess the effects of soy isoflavone protein concentrate and soy lecithin on endothelial function, measured as flow-mediated dilation (FMD) of the brachial artery in healthy postmenopausal women. DESIGN This was a randomized, double-blind, placebo-controlled crossover trial with 25 participants (mean age, 61 years; body mass index, 25.46 kg/m2). The women underwent endothelial fu...

. Egg and soy lecithins are commonly used in the food industry as emulsi®ers (E322). The possibility of residual proteins leads to suspicion of their role in allergic manifestations in subjects allergic to egg or soy. Two cases are reported in which the double-blind, placebo-controlled oral challenge (DBPCOC), the ``gold standard'' of diagnosis, led to con®rmation that lecithin had caused lesio...

The senescence-accelerated mouse (SAMP8) is an animal model used in studies of aging. The purpose of this study was to investigate the effect of different types of dietary lipids on longevity and age-related deterioration in memory in SAMP8 mice. Eight-month-old mice were fed diets with 5% lard (Lard group), 5% soybean oil (Soy group), 2% lecithin +3% soybean oil (Lecithin+Soy group) or 2% fish...

Recent studies suggest that lecithin-rich diet can modify cholesterol homeostasis and hepatic lipoprotein metabolism. Considering the phytotherapeutic impact of lecithin, this work hypothesizes that lecithin administration in hypercholesterolemic patients may reduce cholesterol concentrations by increasing biliary secretion. Total cholesterol and LDL were evaluated after soy lecithin administra...

Abstract This study investigated the effectiveness of foliar application sweet chestnut wood distillate on photosynthetic performance and growth lettuce ( Lactuca sativa L. cv ‘Canasta’), both alone in combination with soybean lecithin used as biosurfactant. Seedlings were treated a either mineral water (control), or 1:500 solutions 3% soy lecithin, plus lecithin. After 1 week, chlorophyll cont...

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...

INTRODUCTION Soybean allergy is one of the most common food allergies especially among children. The Food Allergen Labeling and Consumer Protection Act (FALCPA) in the US requires the labeling of soy lecithin because it is derived from soybeans and may contain a number of IgE-binding proteins, possibly representing a source of hidden allergens. Here we describe a pediatric case of soy allergy m...

BACKGROUND Lecithin has been widely sold as a dietary supplement. 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC) is a phospholipid that does not exist in nature and has been used in vitro to study lipid binding. We tested DMPC in vivo in apolipoprotein (apo) E-null mice. METHODS AND RESULTS DMPC or soy or egg lecithin at 1.0 mg/mL was added to the drinking water of 4-week-old apoE-null fe...

solid lipid nanoparticles of atovaquone (atq-sln) were prepared by high shearhomogenization method using tripalmitin, trilaurin, and compritol 888 ato as the lipidmatrices and phospholipon 90h, tween 80, and poloxamer 188 as the surfactants. optimizationof the formulations was conducted using 6 sets of 24 full-factorial design based on fourindependent variables that were the number of homogeniz...
