Disease relevance of Anisotropy

• Dipolar, quadrupolar and chemical shift anisotropies were calculated as a function of the phosphocholine internal torsion angles by first transforming into a common reference frame affixed to the phosphocholine group prior to motional averaging about the director axis [1].

High impact information on Anisotropy

• The SWAN (Solar Wind ANisotropies) Lyman-alpha all-sky camera on the SOHO spacecraft observed the hydrogen coma of comet C/1999 S4 (LINEAR) from the end of May through mid-August 2000 [2].
• From measurements of orientation anisotropies, we conclude that the slower 75-ps process requires the reorientation of E before ET, similar to E/nucleotide complexes in water [3].
• From the magnitudes of the estimated chemical shift anisotropies, it is predicted that direct observation of selenium in the native enzyme will be feasible if the enzyme concentration can be increased to 0.25 mM tetrameric glutathione peroxidase [4].
• The fluidity of the vesicles was assessed by measuring the fluorescence lifetimes, steady state anisotropies, and differential phase fluorometry of diphenylhexatriene embedded in the vesicles [5].
• We also used the steady state anisotropies, measured under conditions of oxygen quenching, to estimate the motional freedom of the tyrosine residues [6].

Biological context of Anisotropy

• The membrane fluidity of SR was monitored by measuring the changes in the steady state fluorescence anisotropies (rs) using diphenylhexatriene as a probe [7].

Associations of Anisotropy with chemical compounds

• Our findings suggest that the complex band structure causes the observed anisotropies connected with the zinc blende symmetry [13].
• The orthophosphate resonances of bone mineral, synthetic hydroxyapatite and synthetic octacalcium phosphate share identical chemical isotropic shifts, and similar chemical shift anisotropies [14].
• The extrapolated anisotropies (r0) for ferrochelatase-bound MIANS and tryptophan are 0.198 and 0.307 [15].
• Solid state 13C NMR of unlabeled phosphatidylcholine bilayers: spectral assignments and measurement of carbon-phosphorus dipolar couplings and 13C chemical shift anisotropies [16].
• In the absence of ethanol, the measured anisotropies at several wavelengths exhibited almost the same slow decay [17].

Gene context of Anisotropy

• The peaks in this doublet have remarkably different effective chemical shift anisotropies due to the interplay of the CSA, dipolar coupling, and J-coupling tensors [18].
• Motivated by inelastic neutron scattering data on Cs2CuCl4, we explore spin-1/2 triangular lattice antiferromagnets with both spatial and easy-plane exchange anisotropies, the latter due to an observed Dzyaloshinskii-Moriya interaction [19].
• Model-independent analysis of the anisotropies indicates that cofilin increases the rates of the microsecond rotational motions of actin [20].
• Chemical shift anisotropies of F12 and V16 carbonyl carbons are uniaxially averaged in 1,2-dilauryl-sn-glycero-3-phosphatidylcholine (DLPC) bilayers but approach rigid-limit values in the thicker 1-palmitoyl-2-oleoyl-sn-glycerol-3-phosphatidylcholine (POPC) bilayers [21].
• Double-quantum-filtered rotational-resonance MAS NMR in the presence of large chemical shielding anisotropies [22].
