| 1 | Apoptosis induced by 3,7-dinitrodibenzobromonium salts in K_(562)cells显示文摘We evaluated the inhibitory effect of 3,7-dini-trodibenzobromonium salts(cBr)on the proliferation of human chronic myelogenous leukemia K_(562)cell by trypan blue exclusion test and MTT colorimetric assay.The degree of DNA damage in K_(562)cells treated with cBr,was detected by isotopic tracer method(^(3)H-TdR).The morphological changes of these K_(562)cells were examined by fluorescence and electron microscopy.Biochemical characteristics of K_(562)cells were detected by flow cytometry and ^(3)H-thymidine incorporation assay.Findings indicated that cBr could significantly inhibit cell proliferation and result in DNA damage of K_(562)cells.cBr is a new type of immunostimulant and can induce cell apoptosis. | Ruidong MIAO Xiaohui XIA Dongling YANG Minghua LÜ Qin WANG | 2008 | Frontiers in Biology2008，3，3： | 0 |
| 2 | Soliton and bound-state soliton mode-locked fiber laser based on a MoS_2/fluorine mica Langmuir–Blodgett film saturable absorber显示文摘In this article, we report on an experimentally generated soliton and bound-state soliton passively mode-locked erbium-doped fiber laser by incorporating a saturable absorber(SA) made of MoS2∕fluorine mica(FM) that was fabricated with the Langmuir–Blodgett(LB) method. The FM substrate is 20 μm thick and easy to bend or cut,like a polymer. However, it has a higher damage threshold and a better thermal dissipation than polymers.In addition, the LB method can be used to fabricate a thin film with good uniformity. In this study, the modulation depth, saturable intensity, and unsaturated loss of the SA are measured as 5.9%, 57.69 MW∕cm2, and13.4%, respectively. Based on the SA, a soliton mode-locked laser is achieved. The pulse duration, repetition rate, and signal-to-noise ratio are 581 fs, 15.67 MHz, and 65 dB, respectively. By adjusting the polarization controller and pump power, we obtain a bound-state soliton mode-locked pulse. The temporal interval between the two solitons forming the bound-state pulse is 2.7 ps. The repetition rate of the bound-state pulses is proportional to the pump power. The maximum repetition rate is 517 MHz, corresponding to the 33 rd harmonic of the fundamental repetition rate. The results indicate that the MoS2∕FM LB film absorber is a promising photonic device in ultrafast fiber lasers. | RUIDONG Lü YONGGANG WANG JIANG WANG WEI REN LU LI SICONG LIU ZHENDONG CHEN YONGFANG LI HONGYING WANG FUXING FU | 2019 | Photonics Research2019，7，4： | 2 |
