Head and neck squamous cell carcinoma (HNSCC) represents a major health concern worldwide. We applied the matrix-assisted laser desorption/ionization (MALDI) imaging mass spectrometry (IMS) to analyze paired normal (N) and tumor (T) samples from head and neck squamous cell carcinoma as well as liquid chromatography with tandem mass spectrometry (LC-MS/MS) analysis in HNSCC cell lines to identify tumor-associated biomarkers. Our results showed a number of proteins found to be over-expressed in HNSCC.

Background: NAT2, the most important phase II metabolic enzyme for betel quid (BQ), might modify the risk of BQ-related oral and pharyngeal squamous cell carcinoma (OPSCC) in Taiwan.

Study Design: PCR-RFLP and TaqMan assay were conducted for genotyping of NAT2 in 172 OPSCC cases and 170 healthy controls who habitually chewed BQ.

Results: The genotypic and allelic type of T341C and C481T in NAT2 are associated with the risk of OPSCC.

Phosphorylation on certain Ser/Thr-Pro motifs is a major oncogenic mechanism. The conformation and function of phosphorylated Ser/Thr-Pro motifs are further regulated by the prolyl isomerase Pin1. Pin1 has been shown to be prevalently overexpressed in human breast cancer cell lines and cancer tissues and to play a critical role in the transformation of mammary epithelial cells by activating multiple oncogenic pathways.

Purpose: The present study was undertaken to retrospectively evaluate the status of implants in patients subjected to a maxillary sinus lift and immediate implant placement without bone grafting.

Patients And Methods: Seventy-five implants were placed in 47 patients from 2000 to 2006. Lateral approach for the trap-door, open-window method for sinus lifting without placement of either autogenous bone grafts or allogeneic bone substitute was carried out.
