Isolation and heterologous transformation analysis of a pollen-specific promoter from wheat (Triticum aestivum L.).

The promoter of a pollen-specific gene TaPSG719 was isolated from wheat (Triticum aestivum L.) by inverse-PCR (IPCR). Sequence analysis revealed that the promoter contains two cis-acting elements (AGAAA and GTGA) known to confer anther/pollen-specific gene expression which suggests that the promoter of TaPSG719 gene is a pollen-specific one.

Management for postoperative complications of breast augmentation by injected polyacrylamide hydrogel.

Polyacrylamide hydrogel, a new biomaterial, has been used for injected breast augmentation in China since 1997. A series of 30 patients with various complications after injected polyacrylamide hydrogel visited the author's department. Most of these patients had undergone injection of both breasts.
