Preamble

High-Resolution NMR of Solids,la et al 1981). Rapid tumbling in the liquid state averages orientation dependence, so these interactions appear (when they appear at all) as T. relaxation mechanisms rather than as line broadening effects (Lyerla et al 1974). The most important of these are chemical shift anisotropy, dipolar coupli

Application of Solid State NMR to the Lipids of Model and Biological Membranes,lipids were there to stabilize them or to force them into the relevant conformations, as well as to provide a passive hydrophobic barrier. Views have changed! It is now known that lipids play an important role in the immunological and transport properties of membranes, and that different mixes of li

Neural tissue studies have been performed on tissue extracts (Pettegrew et al 1979, 1986, 1987, 1988a, Glonek et al 1982), . brain slices (Cohen et al 1984), and on animals and humans .

NMR Spectroscopy of Tumors,n differences in relaxation times, which are usually longer for tumors, and distortion of surrounding anatomy. While imaging has proven very sensitive, particularly for central nervous system tumors, it has limited specificity, making discrimination of tumors from a number of nonmalignant pathologie

23Na and 7Li NMR Studies of Mammalian Cells: Assessment of Cation Transport and Cytoskeletal Struct processes serve to alter the chemical state of the ion and the position of carefully controlled equilibria. Alterations in Na. transmembrane unidirectional rate constants with resultant alterations in intracellular Na. concentration have been implicated in a number of human disease processes such a
