Lipidomic profiling in Crohn's disease: abnormalities in phosphatidylinositols, with preservation of ceramide, phosphatidylcholine and phosphatidylserine composition. [PDF]
Crohn's disease is a chronic inflammatory condition largely affecting the terminal ileum and large bowel. A contributing cause is the failure of an adequate acute inflammatory response as a result of impaired secretion of pro-inflammatory cytokines by ...

Expansion of Phosphatidylcholine and Phosphatidylserine/Phosphatidylcholine Monolayers by Differently Charged Amphiphiles [PDF]
Abstract Monolayer Technique, Nonionic Detergent, Erythrocyte Shape The degree and time-course of expansion of palmitoyloleoylphosphatidylcholine (PC) and bovine brain phosphatidylserine (PS)/PC (75:25, mol/mol) monolayers at 32 mN/m caused by differently charged amphiphiles (detergents) added to the sub-phase buffer (pH 7.4, 22 °C ...

How do nematodes transfer phosphorylcholine to carbohydrates? [PDF]
An unusual aspect of the biology of nematodes is the attachment of phosphorylcholine (PC) to carbohydrate. The attachment appears to play an important role in nematode development and, in some parasitic species, in immunomodulation.

Structural properties and Raman spectroscopy of lipid Langmuir monolayers at the air-water interface [PDF]
Spectra of octadecylamine (ODA) Langmuir monolayers and egg phosphatidylcholine (PC)/ODA-mixed monolayers at the air-water interface have been acquired. The organization of the monolayers has been characterized by surface pressure-area isotherms.

A New Method for Measuring Edge Tensions and Stability of Lipid Bilayers: Effect of Membrane Composition [PDF]
We report a new and facile method for measuring edge tensions of lipid membranes. The approach is based on electroporation of giant unilamellar vesicles and analysis of the pore closure dynamics. We applied this method to evaluate the edge tension in membranes with four different compositions: egg phosphatidylcholine (EggPC ...

Does litomosoides sigmodontis synthesize dimethylethanolamine from choline? [PDF]
Juvenile female Litomosoides sigmodontis secrete a protein (Juv-p120) highly modified with dimethylethanolamine (DMAE). In an attempt to establish the source of this decoration worms were pulsed with [3H]-choline and [3H]-ethanolamine and the radio ...

Soy Protein Isolate-Phosphatidylcholine Nanoemulsions Prepared Using High-Pressure Homogenization
The nanoemulsions of soy protein isolate-phosphatidylcholine (SPI-PC) with different emulsion conditions were studied. Homogenization pressure and homogenization cycle times were varied, along with SPI and PC concentration. Evaluations included turbidity,

Novel structural features of the ripple phase of phospholipids [PDF]
We have calculated the electron density maps of the ripple phase of dimyristoylphosphatidylcholine (DMPC) and palmitoyl-oleoyl phosphatidylcholine (POPC) multibilayers at different temperatures and fixed relative humidity. Our analysis establishes, for the first time, the existence of an average tilt of the hydrocarbon chains of the lipid molecules ...
