Many natural isotopes have a nuclear spin and can be induced to give radio frequency (RF), nuclear magnetic resonance (NMR) signals in a strong, applied magnetic field B 0 . Important isotopes for biological NMR applications are listed in Table 1 along with their abundance, resonance frequency...
the robustness of the31P NMR spectroscopy tool was first examined in the host and zooxanthellae of the scleractinian coralStylophora pistillata. The potential of this tool was then examined with a series of experiments, which aimed at determining the impact of several environmental conditions on the...
31P and 13C NMR Studies of Acute and Chronic Adriamycin CardiotoxicityChemotherapy has led to significant improvement in the management of cancer (1). However, the use of most common chemothera-peutic agents is limited by their toxicity to one or more organ systems (2鈥 5) (Table 1). ...
