Abstract:
Small unilamellar vesicles (20–100 nm diameter) are model systems for strongly curved lipid membranes, in particular for cell organelles. Routinely, small-angle X-ray scattering (SAXS) is employed to study their size and electron-density profile (EDP). Current SAXS analysis of small unilamellar vesicles (SUVs) often employs a factorization into the structure factor (vesicle shape) and the form factor (lipid bilayer electron-density profile) and invokes additional idealizations: (i) an effective polydispersity distribution of vesicle radii, (ii) a spherical vesicle shape and (iii) an approximat

Abstract:
Drug carriers hold significant promise for precision medicine but face persistent challenges in balancing high encapsulation efficiency with structural preservation during active loading. In this study, we present a microelectromechanical system (MEMS)-driven platform that can generate gigahertz (GHz)-frequency acoustic streaming (1.55 GHz) to enable nondestructive, power-tunable drug encapsulation in lipid vesicles. Utilizing DSPE-PEG-modified bilayers with hydrodynamic shear forces, our method achieves transient membrane permeability that preserves membrane integrity while permitting control

Abstract:
Phosphatidylglycerols represent a large share of the lipids in the plasmamembrane of procaryotes. Therefore, this study investigates the role of charged lipids in the plasma membrane with respect to the interaction of the antiviral saponin glycyrrhizin with such membranes. Glycyrrhizin is a natural triterpenic-based surfactant found in licorice. Vesicles made of 1,2-dioleoyl-sn-glycero-3-phospho-rac-(1’-glycerol) (DOPG)/glycyrrhizin are characterized by small-angle scattering with neutrons and X-rays (SANS and SAXS). Small-angle scattering data are first evaluated by the model-independent modi

Although neither the physiological function nor the mechanism of action of sterol carrier protein 2 (SCP2) is yet completely clear, it is thought that SCP2 interacts with membranes to elicit its biological effects. The results presented here show that the SCP2 N-terminus, composed of two amphipathic α-helices, interacted preferentially with highly curved but not lower-curvature membranes containing anionic phospholipid. CD spectra of SCP2 showed up to 1.2-fold increased α-helical content, on the interaction of SCP2 with small unilamellar vesicles (SUV) (median radius 10-14 nm) but less with la

Abstract:
Changes in a membrane sterol exchange of sickle red blood cells (SS RBC) induced by deoxygenation were studied using the fluorescent cholesterol analogue dehydroergosterol (DHE). DHE uptake by SS RBC membrane was measured by the incubation of SS RBC with small unilamellar vesicles (SUV) containing DHE. Deoxygenation of SS RBC, but not normal RBC, increased the rate of DHE uptake. DHE membrane content after 5 h of incubation with SUV in the cell-to-SUV ratio of 1:1 (mol lipid) was 16.25 +/- 0.94 and 12.22 +/- 0.85% of total sterol for deoxygenated and oxygenated cells, respectively.

Spanlastic is an innovative drug delivery system that traps drugs in a core cavity with a double-layer structure. The term spanlastic comes from the combination of Span and elastic, first introduced in 2011. This plastic is a development of liposomes and niosomes that have been modified sophisticatedly; several types of spanlastic include Multi Lamellar Vesicles (MLV) with a bilayer structure, size 0.5-1.0 microns, easy to make, frequently used, and long-term stable.

However, little is known about their percutaneous penetration and as to at which level they deliver encapsulated drugs. The penetration of multilamellar vesicles (MLVs) and small unilamellar vesicles (SUVs), in comparison to one of their lipid components, was investigated. Methods: Using the fluorescent lipid, Lissamine Rhodamine B-PE (R), as a constituent, MLV and SUV liposomes were prepared, tested, and R, MLV, or SUV were applied in vivo on the back of hairless mice.

Abstract:
Biliary lipid secretion probably involves both ‘micellization’ and ‘vesiculization’ of bile-canalicular membrane lipids. Several hydrophilic organic anions inhibit the secretion of lipids into the bile without altering bile salt secretion [Verkade, Vonk and Kuipers (1995) Hepatology 21, 1174–1189]. Hydrophobic organic anions do not interfere with biliary lipid secretion. We investigated whether the organic-anion-induced inhibition of biliary lipid secretion in vivo could be attributed to inhibition of micellization, by the application of in vitro models of micellization.

Geology<br>M.S.<br>Polycyclic aromatic hydrocarbons (PAHs) are highly hydrophobic and lipophilic and are readily retained by soil surfaces and organic matter. Hence, several techniques have been developed in an effort to economically and effectively remove them from soil solids. Their strong affinity to soil organic matter limits their biodegradation processes by microorganisms, making them persistent in the soil environment. Recently, the use of “small unilamellar vesicles” (SUVs), nano-scale lipid aggregates, has been proposed as a means to enhance these microbial degradations, by effectivel

Abstract:
By means of combining bending elasticity theory with solution thermodynamics of small systems, we demonstrate that unilamellar vesicular liposomes can be thermodynamically stable with a wide range of average sizes depending on the various bending elasticity constants. The average vesicle size increases with increasing bending rigidity (kc) and saddle-splay constant (k¯c), and with decreasing spontaneous curvature (H0). Bilayer aggregates predominate over micelles at lower values of the spontaneous curvature, in the regime of which H0 favours large vesicles. However, small unilamellar vesicles
