Phagocyte respiratory burst in immune responses generates enormous amounts of reactive oxygen species (ROS) to fulfill primary defense against neoplasia. However, the beneficial functions associated with ROS, especially potent oxidant/nucleophile peroxynitrite, an immunological process are still ambiguous. Herein, we report construction and biological assessment cyanine-based fluorescent biosen...

There is evidence that the metabolic responses to afferent and efferent nervous activity are dissociated at sites of neuronal excitation in brain. Whether efferent activity follows afferent activity depends on the responsiveness of postsynaptic neurons, which in turn depends on the summation of excitatory and inhibitory postsynaptic potentials. The afferent activity excites the presynaptic term...

The nonoxidative catalytic dehydrogenation of ethane allows the production ethylene at lower temperatures than those applied in steam crackers. This, however, requires stable catalysts that minimize coke production. Here, we report a single-component, promoter-free, low-loading, Cr-based catalyst exhibiting high activity, long-term stability, and improved regeneration properties for direct to e...
