Asymptomatic, palpable, anterior chest wall lesions in children: is cross-sectional imaging necessary?
All palpable, asymptomatic, anterior chest wall lesions were benign and usually related to normal variations in the bone or cartilage of the chest wall. The low yield of cross-sectional imaging performed for evaluation of these asymptomatic "bumps" should be considered when decisions are made with regard to imaging.
BMP-7 was demonstrated to prevent apoptosis of human disc cells in vitro. One of the antiapoptotic effects of BMP-7 on NP cells might be a result of its inactivation of caspase-3. Collagen production was maintained by addition of rhBMP-7 in an apoptotic environment.
