7空间飞行微重力降低裸藻光合电子传递并改变光合能量分配(英文)显示文摘利用神舟8号飞船的SIMBOX发射机会,对真实微重力影响裸藻光合作用活性进行了研究.我们发现,微重力降低了光合活性(Fv/Fm),提高了细胞内叶绿素a和胡萝卜素含量.快速叶绿素荧光动力学研究显示微重力降低了叶绿素荧光强度,但快速叶绿素荧光动力学曲线的形状(O-J-I-P)没有改变.在微重力处理下裸藻的最大光化学效率(φPo)、用于电子传递的量子产额(φEo)和光合作用性能指数(PIABS and PICS)都明显降低,但单位反应中心吸收的光能(ABS/RC)和单位反应中心耗散的能量(DIo/RC)都明显升高.77K低温荧光光谱实现微重力改变了能量在PSⅠ和PSⅡ之间的分配并出现了红移现象.这些结果表明真实微重力降低光合作用的活性有可能通过两个途径,即抑制裸藻抑制光合电子传递中PSⅡ的受体端和改变PSⅠ的结构从而引起流向PSⅠ的能量传递减少.李小燕 李根保 李敦海 郝宗杰 王高鸿 RICHTER R.

9Diverse Asgard archaea including the novel phylum Gerdarchaeota participate in organic matter degradation显示文摘Asgard is an archaeal superphylum that might hold the key to understand the origin of eukaryotes, but its diversity and ecological roles remain poorly understood. Here, we reconstructed 15 metagenomic-assembled genomes from coastal sediments covering most known Asgard archaea and a novel group, which is proposed as a new Asgard phylum named as the 'Gerdarchaeota'.Genomic analyses predict that Gerdarchaeota are facultative anaerobes in utilizing both organic and inorganic carbon. Unlike their closest relatives Heimdallarchaeota, Gerdarchaeota have genes encoding for cellulase and enzymes involved in the tetrahydromethanopterin-based Wood–Ljungdahl pathway. Transcriptomics showed that most of our identified Asgard archaea are capable of degrading organic matter, including peptides, amino acids and fatty acids, occupying ecological niches in different depths of layers of the sediments. Overall, this study broadens the diversity of the mysterious Asgard archaea and provides evidence for their ecological roles in coastal sediments.Mingwei Cai Yang Liu Xiuran Yin Zhichao Zhou Michael WFriedrich Tim Richter Heitmann Rolf Nimzyk Ajinkya Kulkarni Xiaowen Wang Wenjin Li Jie Pan Yuchun Yang Ji-Dong Gu Meng Li 2020Science China(Life Sciences)2020,63,6:1

14In vivo analysis of intestinal permeability following hemorrhagic shock显示文摘AIM: To determine the time course of intestinal permeability changes to proteolytically-derived bowel peptides in experimental hemorrhagic shock. METHODS: We injected fluorescently-conjugated casein protein into the small bowel of anesthetized Wistar rats prior to induction of experimental hemorrhagic shock. These molecules, which fluoresce when proteolytically cleaved, were used as markers for the ability of proteolytically cleaved intestinal products to access the central circulation. Blood was serially sampled to quantify the relative change in concentration of proteolytically-cleaved particles in the systemic circulation. To provide spatial resolution of their location, particles in the mesenteric microvasculature were imaged using in vivo intravital fluorescent microscopy. The experiments were then repeated using an alternate measurement technique, fluorescein isothiocyanate(FITC)-labeled dextrans 20, to semi-quantitatively verify the ability of bowel-derived low-molecular weight molecules(< 20 k D) to access the central circulation.RESULTS: Results demonstrate a significant increase in systemic permeability to gut-derived peptides within 20 min after induction of hemorrhage(1.11 ± 0.19 vs 0.86 ± 0.07, P < 0.05) compared to control animals. Reperfusion resulted in a second, sustained increase in systemic permeability to gut-derived peptides in hemorrhaged animals compared to controls(1.2 ± 0.18 vs 0.97 ± 0.1, P < 0.05). Intravital microscopy of the mesentery also showed marked accumulation of fluorescent particles in the microcirculation of hemorrhaged animals compared to controls. These results were replicated using FITC dextrans 20 [10.85 ± 6.52 vs 3.38 ± 1.11 fluorescent intensity units(× 105, P < 0.05, hemorrhagic shock vs controls)], confirming that small bowel ischemia in response to experimental hemorrhagic shock results in marked and early increases in gut membrane permeability. CONCLUSION: Increased small bowel permeability in hemorrhagic shock may allow for systemic absorption of otherwise retained proteolytically-generated peptides, with consequent hemodynamic instability and remote organ failure.Tom Alsaigh Marisol Chang Michael Richter Rafi Mazor Erik B Kistler 2015World Journal of Critical Care Medicine2015,4,4:1
