The use of ESR imaging for the rapid determination of diffusion coefficients, D, in anisotropic solvents is reported, and the use of Fourier transforms of the concentration profile to determine D is discussed. An approximate rapid analysis technique is also presented. The ditfusion coefficients for motion perpendicular to the director axis for 4-0x02,2,6,6,-tetramethylpiperidine-I-oxyl (TEMPONE...

When prepared in the liquid-liquid coexistence region, the four-component lipid system distearoyl-phospha-tidylcholine-dioleoyl-phosphatidylcholine-palmitoyl,oleoyl-phosphatidylcholine-cholesterol (DSPC-DOPC-POPC-Cholesterol), with certain ratios of DOPC and POPC, shows striking modulated phase patterns on the surface of giant unilamellar vesicles (GUVs). In this simulation study, we show that ...

Abstract The regulation of the activity and selectivity phospholipase A2 (PLA2), which is capable cleaving fatty acid in second position ( sn-2 ) phospholipid, carried out through membrane-binding catalytic sites enzyme. For hydrolytic activity, PLA2 must first bind to phospholipid membrane, binding efficiency depends on composition membrane. site formed by several tens amino acids its differs ...

Human cell membranes consist of various lipids that are essential for their structure and function. It typically comprises phosphatidylcholine (POPC), phosphatidylethanolamine (POPE), phosphatidylserine (POPS), sphingomyelin (PSM), cholesterol (CHL). Several experimental computational techniques have been employed to characterize the composition human membranes, however, CHL enriched membrane i...

We construct zero-knowledge proofs of plaintext knowledge (PoPK) and correct multiplication (PoPC) for the Regev encryption scheme with low amortized communication complexity. Previous constructions of both PoPK and PoPC had communication cost linear in the size of the public key (roughly quadratic in the lattice dimension, ignoring logarithmic factors). Furthermore, previous constructions of P...
