An ultrastable 1397-nm laser stabilized by a crystalline-coated room-temperature cavity.

State-of-the-art optical cavities are pivotal in pushing the envelope of laser frequency stability below 10-16. This is often achieved by extending the cavity length or cooling the system to cryogenic temperatures to reduce the thermal noise floor. In our study, we present a 30-cm-long cavity that operates at room temperature and is outfitted with crystalline coatings.

[Effects of DCC gene on cell growth and chemosensitivity of ovarian epithelial carcinoma cells].

Objective: To study the effects of DCC gene transfection on cell-growth and chemosensitivity of ovarian epithelial carcinoma cell line HO8910.

Methods: Recombinant eukaryotic expression vector pcDNA3.1(+)-DCC containing DCC gene was introduced by lipofectamine transfection reagent into ovarian epithelial carcinoma cell line HO8910 which does not express DCC endogenously.
