13. Tracking of the kinetic stability of 2 types of total nutrient admixtures containing different lipid emulsions
The physical stability of 2 types of total nutrient admixtures was studied as a function of storage time and temperature. One of them contained only structured triglycerides and the other exclusively long-chain triglycerides as lipid components. To evaluate the possible changes in the kinetic stability of the emulsions and in the surface characteristics of t

14. Molecular organization of histidine-tagged biomolecules at self-assembled lipid interfaces using a novel class of chelator lipids.
In molecular biology, the expression of fusion proteins is a very useful and well-established technique for the identification and one-step purification of gene products. Even a short fused sequence of five or six histidines enables proteins to bind to an immobilized metal ion chelate complex. By synthesis of a class of chelator lipids, we have transferred t

15. Basic Nanostructure of Stratum Corneum Lipid Matrices Based on Ceramides [EOS] and [AP]: A Neutron Diffraction Study
The goal of this study was to investigate the nanostructure of SC lipid model membranes comprising the most relevant SC lipids such as the unique-structured ω-acylceramide [EOS] in a near natural ratio with neutron diffraction. In models proposed recently the presence of ceramide [EOS] and FFA are necessary for the formation of one of the two existent cryst

16. Cell wall and phospholipid composition and their contribution to the salt tolerance of Halomonas elongata.
The salt-tolerant bacterium Halomonas elongata makes a variety of physiological adaptations in response to increases in the salt concentration of its growth medium. The cell walls become more compact and internally coherent. The overall lipid pattern shows an increased amount of negatively charged lipids. In addition, the peptidoglycan composition of H. elon

17. Dynamic, yet structured: The cell membrane three decades after the Singer–Nicolson model
The fluid mosaic membrane model proved to be a very useful hypothesis in explaining many, but certainly not all, phenomena taking place in biological membranes. New experimental data show that the compartmentalization of membrane components can be as important for effective signal transduction as is the fluidity of the membrane. In this work, we pay trib

18. Protein-lipid-lipopolysaccharide association in the superficial layer of Spirillum serpens cell walls.
The backing layer of the Spirillum serpens VHA cell wall, which supports and is bonded to the outer, structured protein layer, was isolated and shown to be similar in composition to the same elements of the outer membrane. It contained a lipopolysaccharide that was similar, but not identical, to that of the intact wall and the same phospholipids. The interac

19. Alpha-toxin of Staphylococcus aureus.
Alpha-toxin, the major cytotoxic agent elaborated by Staphylococcus aureus, was the first bacterial exotoxin to be identified as a pore former. The protein is secreted as a single-chain, water-soluble molecule of Mr 33,000. At low concentrations (less than 100 nM), the toxin binds to as yet unidentified, high-affinity acceptor sites that have been detected o
