Based on the cluster structure of 4n-nucleus, a parity-dependent potential is derived by using a proper nuclear orbital wave function and the folding method.

Recently, microbubble (MB) enhanced ultrasound cavitation was found to have great potential in therapy because MB can act both as a drug carrier and a cavitation nucleus.

FGF-2 has been shown to retain the differentiation potential of monolayer expanded chondrocytic cells. However, its effect on nucleus pulposus cells is not known.
