Is overgrowth of costal cartilage the etiology of pectus excavatum?
The results revealed that, in PE patients, relative costal cartilage lengths were not longer than in healthy controls. We conclude that the overgrowth of costal cartilage is not the etiology of PE.
These studies present clear evidence that neuroprotection by selective N-type calcium channel antagonists is mediated directly through neuronal calcium channels. In contrast, the neuroprotective effects of dihydropyridines may be mediated through vascular calcium channels or indirectly through actions in other brain regions.
