Abstract:
Simple enzymatic methods were developed for the synthesis of lysolecithin, glycerolyzed lecithin and hydrolyzed lecithin. The products were characterized in terms of their acetone insoluble matter, hexane insoluble matter, moisture, phospholipid distribution and fatty acid composition. The HLB value ranges of different products with different acid values were detected. The efficiency of optimally hydrolyzed lecithin was examined at high calcium ion, low pH, and aqueous solutions and compared with commercially available standard lecithin-based emulsifiers. Overall, lysolecithin powder was prove

Abstract:
Here, we report a facile and effective one-pot approach to prepare uniform amylose-based polymeric microparticles (PMPs) through enzymatic synthesis of short-chain amylose (SCA) followed by spontaneous self-assembly of the SCA in the presence of lecithin. The effect of lecithin on nucleation and growth kinetics of amylose microparticles was investigated by monitoring the turbidity of reaction solution and the size of particles over the course of the self-assembly process. The results suggest that lecithin played a critical role in controlling the self-assembly kinetics to form uniform amylose

Abstract:
The enzyme lecithin–cholesterol acyltransferase (LCAT) transfers an acyl chain from lecithin to cholesterol or oestradiol, thus playing a crucial role in reverse cholesterol transport and follicular synthesis of potent long-lived oestrogens. The mechanism of catalysis is biphasic, as it is based on a phospholipase and an esterifying activity. Sulfhydryl groups were previously reported to be required for the esterification step. Lecithin–cholesterol acyltransferase has previously been shown to be inhibited by thiol oxidants such as peroxynitrite. Peroxynitrite also converts tyrosine to nitrotyr

Abstract:
Lecithin-cholesterol acetyltransferase (LCAT) is involved in the synthesis of plasma cholesteryl esters and is pivotal in the maturation of plasma high-density lipoprotein (HDL) and conversion of HDL3 to HDL2. In nephrotic syndrome (NS), the ratio of HDL2 to HDL3 is low even though the total concentration of HDL is generally normal. We hypothesize that the reduced HDL2/HDL3 ratio in NS is due to urinary losses of LCAT, leading to plasma LCAT deficiency. To test this hypothesis, Sprague-Dawley rats were randomized to NS (given 130 mg puromycin aminonucleoside on day 1 and 60 mg ip on day 14) or

Abstract:
Several reproductive hormones were reported to be involved in regulating egg yolk precursor synthesis in chickens; however, the mechanism that shows how the liver-blood-ovary signal axis works in relation to age changes has not been reported yet. Therefore, in this study, we observe the morphology and histology of the liver and ovary and determine the serum biochemical parameters and the expression abundance of the critical genes from d90 to 153. Results show that the body weight and liver weight were significantly increased from d132, while the ovary weight increased from d139. Aside from the

Abstract:
Lipid A, the active component of bacterial endotoxin, stimulates multiple cell types, including glomerular mesangial cells (MC), and yet the molecular mechanisms of cell activation remain unclear. Lipid A, in its monosaccharyl form, structurally resembles the biologically active lipid phosphatidic acid (PA). Given this, it was postulated that lipid A activates cells by acting as a structural and functional mimetic of PA. Lipid A was found to specifically stimulate an MC lyso-PA acyl transferase activity, leading to enhanced synthesis of sn-2-unsaturated forms of PA. Sn-2-unsaturated PA itself,

Abstract:
Choline, the beta-hydroxyethyltrimethylammonium ion, is a strong base containing a trimethylated quaternary nitrogen. Choline occurs widely in biological materials as the compound itself, as acetylcholine and as various phospholipids. In feed ingredients and crude unprocessed fat sources, most choline is present as phosphatidylcholine (lecithin). Although soybean, soybean meal, rapeseed meal, fish meal and dried yeast are relatively rich sources of choline, the bioavailability of choline in these feedstuffs is only moderate. In dairy ruminants, choline is extensively degraded in the rumen. For

AbstractRecent research on the neurochemical deficits that accompany Alzheimer's disease (AD), senile dementia (SD) and Korsakoff's dementia (KD) have prompted renewed interest in the involvement of central cholinergic systems in learning and memory processes. Evidence for the role of cholinergic systems in the dementias is now overwhelming and has been reviewed in detail elsewhere, e.g. Briefly, such evidence includes findings of decreased cortical activity of the cholinergic marker enzyme choline-acetyltransferase (CAT), reduced activity of the acetylcholine degrading enzyme acetylcholineste

The development of nanocomposite hydrogels that take advantage of hierarchic building blocks is gaining increased attention due to their added functionality and numerous biomedical applications. Gathering on the unique properties of these platforms, herein we report the synthesis of bioactive nanocomposite hydrogels comprising naringin-loaded salmon-derived lecithin nanosized liposomal building blocks and gelatin methacryloyl (GelMA) macro-sized hydrogels for their embedding. This platform takes advantage of liposomes’ significant drug loading capacity and their role in hydrogel network reinfo

Hybrid and antimicrobial nanoparticles (NPs) of poly (methyl methacrylate) (PMMA) in the presence of poly (diallyl dimethyl ammonium) chloride (PDDA) were previously obtained by emulsion polymerization in absence of surfactant with low conversion. In the presence of amphiphiles such as cetyl trimethyl ammonium bromide (CTAB), dioctadecyl dimethyl ammonium bromide (DODAB) or soybean lecithin, we found that conversion increased substantially. In this work, the effect of the amphiphiles on the NPs core-shell structure and on the antimicrobial activity of the NPs was evaluated. NPs dispersions cas

Abstract Introduction: Iron deficiency is one of the most widespread nutritional deficiencies. Globally two billion people are suffering from iron- deficiency anemia (Hermida et al., 2010). Oral therapy for iron deficiency is mainly based on immediate release formulations of ferrous iron. However, modified formulations have been marketed to reduce gastrointestinal side effects and to prevent iron instability in the gastrointestinal tract. Overcoming biological barriers, including the gastrointestinal epithelial barriers, is a great challenge for pharmaceutical research and thus there is a need
