31P nuclear magnetic resonance (NMR) studies of creatine phosphokinase (CPK) kinetics using saturation transfer techniques are reported. The phosphocreatine (PCr) and adenosine triphosphate (ATP) levels in perfused hearts can be altered experimentally by stopping the flow of perusate (ischemia) to the heart for 35-min periods, followed by reperfusion to(More)
A large number of samples of human neoplastic and abnormal nonneoplastic tissues were studied by nuclear magnetic resonance spectrometry in order to evaluate the possible role of this technique in the diagnosis of cancer. The spin-lattice magnetic relaxation times (T1) of abnormal nonneoplastic tissue were longer, in many instances, than those of malignant(More)
DNA 'assembly' from 'building blocks' remains a cornerstone in synthetic biology, whether it be for gene synthesis (∼ 1 kb), pathway engineering (∼ 10 kb) or synthetic genomes (>100 kb). Despite numerous advances in the techniques used for DNA assembly, verification of the assembly is still a necessity, which becomes cost-prohibitive and a logistical(More)
