(18)F labeled natural amino acids have been introduced as promising tumor imaging agents. A novel [(18)F]fluoro amino acid analog 1-[(18)F]fluoroethyl-L-tryptophan (1-[(18)F]FETrp) was designed and synthesized by a two-pot three-step procedure, including the synthesis of 1-[(18)F]fluoro-2- (tosyloxy)ethane, the [(18)F]fluoroethylation of the precursor(More)
BACKGROUND A high incidence of orofacial clefts is reported in China, but no data has shown the relation between cleft types and the incidence of other defects so far. The aim of this study is to assess the incidence of congenital heart diseases and other organic defects associated with different types of orofacial clefts. METHODOLOGY AND PRINCIPAL(More)
Radiotherapy (RT) is a major modality of hepatoma treatment. However, liver tumors often acquire radioresistance, which contributes to RT failure. The exact mechanisms of the radioresistance in hepatoma cells are largely unknown. Glutathione S-transferase M3 (GSTM3) is a phase II transferase, however, recent studies have suggested that GSTM3 is a potential(More)
OBJECTIVE To evaluate the potential role of BME-10X collagen/hydroxyapatite (HA) bone graft in periodontal tissue regeneration. METHODS Four 18 months old male beagles in the experiment were treated with non-surgical periodontal therapy. At the sites of mandibular 3rd and 4th premolars at the time of dogs were treated with non-surgical periodontal therapy(More)
