Pollen of Petunia hybrida was germinated in artificial medium. At the beginning of the incubation, a large amount of proline, which comprises about half of the total free amino acid pool, was released into the medium. Part of this proline is reutilized by the pollen. Uptake of radioactive amino acids and their incorporation into proteins were studied. The(More)
Proline degradation inPetunia pollen germinated in vitro was studied in cultures supplemented with [14C]proline labeled at different positions. Despite its abundance in the cell, this amino acid is only a minor substrate for respiration. Proline is partially converted via the citrate cycle into metabolites which can be traced in the ethanol-insoluble(More)
The purpose of this study was to evaluate the clinical and radiographic outcomes of modified pedicle subtraction osteotomy (mPSO) for thoracolumbar post-tubercular kyphosis in pediatric patients. From January 2008 to August 2012, 26 consecutive pediatric patients with thoracolumbar post-tubercular kyphosis underwent modified pedicle subtraction osteotomy(More)
