(1) The mixtures of stearic (SA) and arachic acids (AA) with DMPC and DSPC show phase diagrams of the peritectic type, with a region of solid phase immiscibility from 0 to 28.5 mol% of fatty acid.
(2) Ethyl cellulose was dissolved in a water immiscible, volatile organic solvent, containing sulphadiazine as a model drug.
(3) Below 45 mN m-1 and in the absence of Ca2+ no indications of phase immiscibility were observed.
(4) In a condensed host lipid, the probe is partially immiscible, and segregates to form a heterogeneous film from which it is readily collapsed.
(5) Washing bacteria by centrifugation through a water-immiscible layer of silicones.
(6) The acid--immiscible with lecithin--forms well defined pure acid domains in the monolayer.
(7) However, the equilibrium surface film contains only the 2:1 complex and, therefore, 2:1 complex is also immiscible with cholesterol in surface films.
(8) Hexabrix and tolazoline exhibited transient immiscibility.
(9) Simultaneous measurements of the pressure in terminal lymphatics and interstitial tissue have been made in the exteriorized cat mesentery superfused with either physiological salt solution (Krebs solution) or a water-immiscible fluorocarbon, FC-80.
(10) The properties of perfluorocarbon liquid--clear, water immiscible, specific gravity twice that of water--make it an important adjunct to treatment of complex retinal detachments.
(11) Mixtures of POPC with DPPC or with DSPC exhibit gel phase immiscibility over the composition range 0-75% DPPC (or DSPC).
(12) Distribution of cephalotin, 2-tienylacetic acid, phenacetyl-D-(--)-alpha-aminophenylacetic acid, weak acids and D-(--)-alpha-amino-phenylacetic acid methyl ether, a weak base in two-phase systems containing two immiscible liquid phases was studied.
(13) Our DSC results indicate that the width of the phase transition observed at high peptide concentration is inversely but discontinuously related to hydrocarbon chain length and that gel phase immiscibility occurs when the hydrophobic thickness of the bilayer greatly exceeds the hydrophobic length of the peptide.
(14) Saturated and unsaturated phosphatidylcholine (PC)-cholesterol membranes have been studied, with a special attention paid to fluid-phase immiscibility in cis-unsaturated phosphatidylcholine (PC)-cholesterol membranes as previously proposed and to the three-dimensional structure of the membrane.
(15) When a small amount of human blood was injected, it flowed immiscibly to the lowest level, displaced the bile, and formed a clot of pure blood.
(16) Complete destruction of undiluted DMS or DMS in solvents miscible with water (methanol, ethanol, DMSO, DMF, acetone) or solvents partially miscible or immiscible with water (toluene, p-xylene, benzene, 1-pentanol, ethyl acetate, chloroform, carbon tetrachloride, acetonitrile) could be obtained using any of the above methods.
(17) Below 20 mol % cholesterol the DPPC mixtures give heat-capacity curves each of which can be resolved into a narrow and a broad peak, suggesting the coexistence of two immiscible solid phases; above 20 mol % only the broad peak is observed and this disappears at about 50 mol %.
(18) It operates with commonly used HPLC eluents and immiscible organic solvents as long as the two phases remain immiscible.
(19) In vesicles composed of two lipids which are partially immiscible in the gel state, a size increase was observed at temperatures which mainly overlapped the range of temperatures of the lipid phase transition.
(20) Some anionic sulphate and sulphonate detergents were also unsatisfactory being immiscible with Kober reagent.
