In contrast, in studies where the ... breast tumors [29]. These calculations also do not use a dose reduction for HDR because these dose reductions may not be as accurate as distance from the catheter in...

... were washed twice in PBSCM supplied with 100 mm glycine, and incubated for 20 min to quench further cross-linking. The quenching buffer was removed by washing twice in PBSCM, and the cells were then ... caused the biotinylated p25a tracer to remain in the bottom frac- tions, thus demonstrating that the flotation was due to binding to vesicles. Because the vesicle-bi...

... proteinase was deter- mined by comparing the result to a standard curve con- structed using known amounts of the proteinase. Chymase (7 nm) was assayed using Suc-Ala-Ala-Pro-Phe-pNA (5 mm). Tryptase ... [30–33]. These findings imply that mast cells are involved in thrombosis and fibrinolysis. In fact, mast cells express tissue-type plasminogen activator and urokinase-type plasmi...

Although the results from the mutational studies of the receptor N-domain are inconclusive, they do indi- cate that the binding involves interactions ... is the net number of protons transferred during binding. To investigate whether there is a net proton transfer on IL-8 binding to the receptor N-domain, ITC measuremen...

As a first step towards this goal we set out to develop a mitochondria-targeted DNA- alkylating reagent to determine whether it was possible to alkylate ... due to binding to the matrix-facing surface of the inner membrane [45]. When the membrane potential was dissipated by addition of the uncoupler FCCP, mitoD...
