探讨列当水提物(OLE)对谷氨酸(Glu)诱导的氧化衰老的影响及其机制。采用MTT法检测Glu、OLE对细胞增殖活力的影响;根据MTT试验结果确定最佳给药浓度与时间,设置空白组、Glu组(模型组)、OLE低、中、高质量浓度组(1.56、3.13、6.25 g/L)。通过衰老相关β-半乳糖苷酶染色(SA-β-Gal)检测模型组与OLE组的衰老程度;检测各组超氧化物歧化酶(SOD)和谷胱甘肽过氧化物酶(GPX)活性及丙二醛(MDA)含量;通过流式细胞仪分析OLE作用12 h后细胞的周期分布;通过Western blot检测Bcl-2、Bax、ERK1/2及磷酸化ERK1/2蛋白的相对表达水平。结果显示:与空白组相比,模型组SOD、GPX活性显著降低(P<0.05),MDA含量显著上升,β-Gal染色阳性率显著上升,而经过OLE预处理再用Glu诱导组的MDA含量出现下降,SOD、GPX活性升高;与模型组相比,OLE预处理能抑制细胞凋亡(P<0.05),作用于PC12细胞的G2期促进细胞增殖;与模型组相比,OLE中剂量组可显著提高ERK1/2、p-ERK1/2、Bcl-2的表达,降低Bax蛋白表达(P<0.05)。结果表明OLE可通过提高SOD、GPX活性,抑制MDA的产生,纠正Glu造成的氧化损伤,抑制细胞凋亡;通过提高ERK1/2、p-ERK1/2、Bcl-2的表达,降低Bax蛋白表达拮抗Glu带来的氧化损伤,对Glu引起的氧化衰老有预防作用。

Employing recently developed magneto-optical trap recoil ion momentum spectroscopy(MOTRIMS)combined with cold atoms,strong laser pulse,and ultrafast technologies,we study momentum distributions of the multiply ionized cold rubidium(Rb)induced by the elliptically polarized laser pulses(35 fs,1.3×10^15 W/cm^2).The complete vector momenta of Rb^n+ions up to charge state n=4 are recorded with extremely high resolution(0.12 *** Rb^+).Variations of characteristic multi-bands are displayed in momentum distributions because the ellipticity varies from the linear to circular polarization,are interpreted qualitatively with the classical overbarrier ionization *** momentum spectroscopy of cold heavy alkali atoms presents novel strong-field phenomena beyond the noble gases.

Comparative Forecast Verification for a Rainfall Process Caused by the Northeast Cold Vortex in Different Valid Time

引用

Meteorological and Environmental Research 2018年第1期9卷 44-48页

作者： Wang Ju Zhuo Peng ma huanyu Huang Hong College of Meteorology and Oceanology National University of Defense Technology Unit 61741 PLA

The forecast of precipitation,height,temperature,divergence and water vapor divergence during a rainfall process in Northeast China during June 13-14 in 2012 were analyzed. The results showed that the rainfall process in Northeast China on June 13 and 14 in 2012 was mainly caused by the typical northeast cold vortex at 500 h Pa,southwest low-level jet at 850 and 700 h Pa,and surface cyclone. The rainfall forecast valid in 60 h was obviously better than those valid in 36 and 84 h,and the forecast error mainly resulted from the prediction error of vertical water vapor transportation.

The development of new electron transporting layer(ETL) materials to improve the charge carrier extraction and collection ability between cathode and the active layer has been demonstrated to be an effective approach to enhance the photovoltaic performance of organic solar cells(OSCs). Herein, water-soluble carbon dots(CDs) as ETL material have been creatively synthesized by a vigorous chemical reaction between polyethylenimine(PEI) and 3,4,9,10-perylenetetracarboxylic dianhydride(PTCDA) via a simple one-step hydrothermal method. Taking full advantage of the high electron transfer property of PTCDA and the work function(WF) reduction ability of PEI, CD gained high electron mobility due to its large π-conjugated area and reduced the WF of indium tin oxide(ITO) by 0.75 e V. As for the photovoltaic performance of devices, inverted OSCs based on CDs have achieved a high power conversion efficiency(PCE) of 17.35%, exhibiting no burn-in effect with no reduction in PCE after more than 4000 h of storage. The successful application of CDs in OPV has developed a new avenue for designing efficient ETL materials that benefits the photovoltaic performance of OSCs.
