| 1 | 利用Arecibo射电望远镜河外21-cm巡天数据进行中性氢吸收线的探测研究显示文摘利用Arecibo射电望远镜40%的ALFALFA(Arecibo Legacy Fast Arecibo L-band Feed Array)河外中性氢巡天数据,探讨了进行中性氢吸收线'盲寻'的过程与方法,并给出了搜寻吸收线的一些初步结果:(1)探测到的中性氢吸收源的数量共有10个,其中5个为文献中已知源,其余新发现的吸收线源需要进一步的研究与证实.(2)利用探测灵敏度给出了探测区域中性氢柱密度的上限,这些上限的频率统计分布显示阻尼莱曼α吸收线系统(DLAs)中的中性氢气体的平均自旋温度与覆盖因子的比值Ts/f很可能大于500K.射电干扰与驻波是影响Arecibo河外中性氢吸收线探测的两个重要因素,也将进行一定的分析以及讨论相应的解决方法等.正在建设中的500 m口径射电望远镜FAST(The Five-hundred-meter Aperture Spherical Telescope)与Arecibo射电望远镜属于相似类型,但在灵敏度、频带宽度、观测天区范围等方面都将有较大的提高,结合目前的研究进展对将来FAST在中性氢吸收线方面的研究也给出了一定的展望. | 吴忠祖 HAYNES Martha P GIOVANELLI Riccardo 朱明 陈如荣 | 2015 | 天文学报2015，56，2： | 2 |

| 3 | The detrimental effects of lipopolysaccharideinduced neuroinflammation on adult hippocampal neurogenesis depend on the duration of the pro-inflammatory response显示文摘Adult hippocampal neurogenesis is a finely tuned process regulated by extrinsic factors. Neuroinflammation is a hallmark of several pathological conditions underlying dysregulation of neurogenesis. In animal models, lipopolysaccharide(LPS)-induced neuroinflammation leads to a neurogenic decrease mainly associated to the early inflammatory response. However, it is not well understood how the neuroinflammatory response progresses over time and if neurogenesis continues to be diminished during the late neuroinflammatory response. Moreover, it is unknown if repeated intermittent administration of LPS along time induces a greater reduction in neurogenesis. We administered one single intraperitoneal injection of LPS or saline or four repeated injections(one per week) of LPS or saline to young-adult mice. A cohort of new cells was labeled with three 5-bromo-2-deoxyuridine injections(one per day) 4 days after the last LPS injection. We evaluated systemic and neuroinflammation-associated parameters and compared the effects of the late neuroinflammatory response on neurogenesis induced by each protocol. Our results show that 1) a single LPS injection leads to a late pro-inflammatory response characterized by microglial activation, moderate astrocytic reaction and increased interleukin-6 levels. This response correlates in time with decreased neurogenesis and 2) a repeated intermittent injection of LPS does not elicit a late pro-inflammatory response although activated microglia persists. The latter profile is not accompanied by a continued longterm hippocampal neurogenic decrease. Hereby, we provide evidence that the neuroinflammatory response is a dynamic process that progresses in a milieu-dependent manner and does not necessarily lead to a neurogenic decrease, highlighting the complex interaction between the immune system and neurogenesis. | Martha Pérez-Domínguez Evangelina ávila-Mu?oz Eduardo Domínguez-Rivas Angélica Zepeda | 2019 | Neural Regeneration Research2019，14，5： | 2 |
