Metabolomics of a mouse model of preeclampsia induced by overexpressing soluble fms-like tyrosine kinase 1.

Preeclampsia (PE) is a leading cause of maternal morbidity and mortality. Nicotinamide has beneficial effects on PE. In this study, we evaluated the effect of nicotinamide on placental development using a PE mouse model.

Topical treatment of oral cavity and wounded skin with a new disinfection system utilizing photolysis of hydrogen peroxide in rats.

The present study aimed to evaluate the acute locally injurious property of hydroxyl radical generation system by photolysis of H(2)O(2), which is a new disinfection system for the treatment of periodontitis developed in our laboratory. Firstly, generation of the hydroxyl radical by a test device utilizing the photolysis of H(2)O(2) was confirmed by applying an electron spin resonance (ESR)-spin trapping technique. Secondly, the bactericidal effect of the device was examined under a simulant condition in which Staphylococcus aureus suspended in 1 M H(2)O(2) was irradiated with laser light emitted from the test device, resulting in substantial reduction of the colony forming unit of the bacteria within a short time as 2 min.
