Synthesis and Characterization of β-Tricalcium Phosphate Derived From Haliotis sp. Shells.

Purpose: To develop a methodology for the synthesis of β-tricalcium phosphate (β-TCP, Ca3(PO4)2) from the shell of Haliotis sp. (abalone shell) and to verify its characterization and biocompatibility.

Materials And Methods: Calcium oxide (CaO) was synthesized from abalone shell by sintering and was suspended in distilled water to prepare calcium hydroxide (Ca(OH)2).

Berberine-induced anticancer activities in FaDu head and neck squamous cell carcinoma cells.

In the present study, we investigated berberine‑induced apoptosis and the signaling pathways underlying its activity in FaDu head and neck squamous cell carcinoma cells. Berberine did not affect the viability of primary human normal oral keratinocytes. In contrast, the cytotoxicity of berberine was significantly increased in FaDu cells stimulated with berberine for 24 h.

Berberine induces FasL-related apoptosis through p38 activation in KB human oral cancer cells.

In the present study, we examined the anticancer properties of berberine in KB oral cancer cells with a specific focus on its cellular mechanism. Berberine did not affect the cell viability of the primary human normal oral keratinocytes that were used as a control. However, the viability of KB cells was found to decrease significantly in the presence of berberine in a dose-dependent manner.
