(1) Likewise, they had little or no effects on the fluorescence anisotropy of TMA-DPH, which is also thought to be located in the interfacial region of the lipid bilayer, either when the probe was located in the outer layer of the plasma membrane or when the probe was located in the inner membrane compartment.
(2) Time-resolved tyrosine fluorescence anisotropy shows global correlation times broadly in agreement with the NMR results, but with an additional faster correlation time [approximately 600 ps].
(3) This technique is sensitive to the optical anisotropy within the muscle, including that due to intrinsic properties of the protein molecules as well as that due to the regular arrangement of proteins in the surrounding medium.
(4) In terms of segmental motion and anisotropy of packing the lipoprotein-X bilayer closely resembles a model bilayer system consisting of phosphatidylcholine, lysophosphatidylcholine, sphingomyelin and cholesterol mixed in the same molar ratio as in lipoprotein-X.
(5) Diffusional anisotropy of water protons, induced by nonrandom, directional barriers which hinder or retard water motion, is measurable by MRI.
(6) The fluorescence anisotropy changes observed in A-1 (H1N1) influenza and Sendai parainfluenza viruses in aqueous suspensions when formaldehyde (0.1 to 1.0 p.c.)
(7) Linear regression analysis of creatine kinase activity in sera and DPH fluorescence anisotropy in lymphocytes from DMD patients showed a negative correlation (r = -0.93, p less than 0.001).
(8) The 31P nuclear magnetic resonance anisotropies of dispersions of diacylphosphatidic acid and diacylphosphatidylserine were slightly increased in the presence of cytochrome c: no increase was observed with cardiolipin.
(9) Acuity for the direction of drift for these stimuli is of the same order of precision as orientation acuity for static or drifting gratings, and exhibits a meridional anisotropy that favours the principal meridians.
(10) Based on the morphology and magnetic anisotropy of the rod outer segment, the major phospholipid peak is attributed to the flat part of the disk membranes while the phospholipids of the plasma membrane are thought to contribute only to the minor peak.
(11) Exposure of EC to AA increases membrane "fluidity" as measured by fluorescence anisotropy using 1,6-diphenyl-1,3,5 hexatriene as a fluorescent probe.
(12) Concentration-dependent dissociation of dimers of goat brain tubulin S and tubulin was studied by fluorescence anisotropy.
(13) Changes in the mode of DNA packaging in nuclei during spermatogenesis were studied by measuring of the fluorescence anisotropy decay of an ethidium dye intercalated in the DNA in whole nuclei.

(15) The coenzyme-binding site in mitochondrial malate dehydrogenase from pig heart was studied using dynamic fluorescence anisotropy decay.
(16) Experiments were performed to study biaxial anisotropy in relaxed canine carotid arteries subjected to a wide range of longitudinal lengths and transmural pressures.
(17) This increase, as well as the increase in fluorescence anisotropy upon RecA binding, was very similar to that which resulted from sucrose addition to free poly(d epsilon A).
(18) Membrane microviscosity was evaluated by the fluorescence anisotropies of diphenylhexatriene (DPH) and its cationic derivative trimethylamino-diphenylhexatriene (TMA-DPH).
(19) Steady-state fluorescence anisotropy, fluorescence lifetime, and 13C NMR relaxation data are used in concert to provide quantitative information about the dynamics of a single 13C-labeled tryptophan side chain at position 19 in lipid-bound MLT, and at positions 17, 11, and 9, respectively, in lipid-bound MLT analogues.
(20) The data on DPH anisotropy, pyrene excimerization and induction resonance energy transfer (IRET) from PM proteins to pyrene provided the evidence for age-dependent decrease in PM lipid phase fluidity inclusive of that of annular lipid.
