Modification of the free alkali light chains of myosin by iodoacetylation results in a much lower extent of exchange into myosin subfragment 1 by the thermal hybridization procedure (Burke, M., and Sivaramakrishnan, M. (1981) Biochemistry 20, 5908-5913). As reported by others (Wagner, P. D., and Stone, D. B. (1983) J. Biol. Chem. 258, 8876-8882), free alkali light chains modified by iodoacetate...

Spin-exchange optical pumping [1] uses spin-exchange collisions between He atoms and optically pumped Rb atoms to produce large quantities of highly spin-polarized He for a variety of applications, including medical imaging [2] and spin-polarized targets [3]. The efficiency of polarized He production is determined by two fundamental rates: the Rb-He spin-exchange rate and the Rb spinrelaxation ...

Contact ionization (doped) sources used in current Heavy Ion Fusion (HIF) experiments consist of a porous tungsten substrate doped with an alkali carbonate. During the early stages of the heating cycle (T ~ 600 °C), the carbonate breaks down and releases the alkali atoms that then diffuse through the substrate. At the emitter surface there is a balance between the fast desorption rate of the al...

Some pulp mills expect to produce viscose fiber by means of pre-existing pulp production lines as used for conventional kraft pulp having a relatively high content of hemicellulose. In the present study oxygenreinforced alkali extraction was used to dissolve the oxidized lignin, which increased the content of alpha cellulose and increased the degree of mercerization. This paper considers the in...

We present a relativistic formulation of the optimized effective potential method (ROEP) and its implementation within the Korringa-Kohn-Rostoker multiple scattering formalism. The scheme is an all-electron approach, treating core and band states formally on the same footing. We use exact exchange (EXX) as an approximation to the exchange correlation functional. Numerical four-component wavefun...

in medicine, patent blue violet (pbv) is utilized for staining lymphatic vessels in sentinel lymph node (sln) surgery. moreover, pbv (also called e131 ) is used as food additive. we report on a 51-year-old non-atopic female with early breast cancer, who was scheduled for sln excision and experienced an intra-operative anaphylactic reaction. in diagnostics the skin prick test (spt) was positive ...
