Abstract: Methods and systems for delivering a very potent vasodilator that has the ability to treat and prevent heart failure including delivering microcapsules containing ?-CGRP, which show no toxicity and lowers blood pressure similar to the native peptide, where this new compound could greatly enhance the lifespan of patients suffering from heart failure.

Abstract: Use of metformin in inhibition of growth and/or viability of human neuroblastoma cells is described. Use of metformin in inhibition of growth and/or viability of neuroblastoma cancer stem cells is also described. The metformin is shown to be effective both in vitro and in vivo in inhibition of growth and/or viability of neuroblastoma cells of multiple different genetic backgrounds.

Abstract: Use of sparstolonin B in inhibition of growth and/or viability of human neuroblastoma cells is described. The sparstolonin B can be naturally derived from the Chinese herb Sparganium stoloniferum or can be synthetic. The sparstolonin B is shown to be effective both in vitro and in vivo in inhibition of growth and/or viability of neuroblastoma cells of multiple different genetic backgrounds including N-myc amplified with wild p53 neuroblastoma cells, N-myc amplified with mutated p53 neuroblastoma cells, and N-myc nonamplified neuroblastoma cells.
