The objective of this study was to explore the effects of cisplatin on growth of human oral cancer cells, and the differential expression of two micro RNAs (miRs), miR-633 and miR-210 in vitro and in vivo. The growth-inhibiting effects of cisplatin on the human oral cancer cell line SCC25 were assessed by MTT assay, while cell apoptosis was examined using DAPI staining. In addition, the effects...

A high-density dielectric rectangular grating is designed for color separation in a Fresnel diffraction field. The Fresnel field distribution is analyzed and the optimization conditions for color separation are given. The process of the modes propagating and energy exchanging with the diffraction orders are expressed by modal method. The color separation for different polarizations can be reali...

We have developed a low-cost, non-contact, multispectral photoacoustic microscope system to study the functional parameters of cellular choromophores. The system uses low power continuous wave lasers and a photoacoustic sensor made of a kHz microphone coupled to a resonant chamber. Methemoglobin has relatively high optical absorption at 500 nm and 630 nm. Moreover, it has an almost the same opt...

Hyaluronan (HA) in the endothelial glycocalyx serves as a mechanotransducer for high-shear-stress-stimulated endothelial nitric oxide synthase (eNOS) phosphorylation and nitric oxide (NO) production. Low shear stress (LSS) has been shown to contribute to endothelial inflammation and atherosclerosis by impairing the barrier and mechanotransduction properties of the glycocalyx. Here we focus on t...
