Instead of the traditional heating method, the cavity length of an internal-mirror He-Ne laser is controlled by air cooling which is implemented by a mini cooling fan. The responsive property of the cooling fan and the thermal expansion of the internal-mirror laser tube are investigated. According to these investigations, a controlling system is designed to(More)
BACKGROUND This study is to investigate the association of fibroblast growth factor receptor 2 (FGFR2) rs2981582, trinucleotide-repeat-containing 9 (TNRC9) rs3803662, rs12443621, and leukocyte-specific protein 1 (LSP1) rs3817198 polymorphisms with breast cancer and mammographic density in Han Chinese population.

A direct phase coherent determination of the absolute frequency of the a15 component in the R(12) 26-0 and b10 component in the R(106) 28-0 transitions in I2 at 543 nm has been made at the International Bureau of Weights and Measures. Lasers from the Czech Metrology Institute (Czech Republic), the National Institute of Metrology (China), the Centro Nacional(More)
The purpose of this study was to investigate the combined effect of ultrasound and SonoVue microbubble on CD4(+)CD25(+) regulatory T cells (Tregs) viability and to explore the appropriate parameters for Tregs transfection. Tregs were separated from peripheral venous blood of patients with hepatocellular carcinoma and seeded in 96-well plates. The optimal(More)
