1Water isotope variations in the snow pack and summer precipitation at July 1 Glacier, Qilian Mountains in northwest China显示文摘This paper presents the stable isotope data of the snow pack and summer precipitation collected at the July 1 Glacier, Qilian Mountains in northwest China and analyses their relationships with meteorologi- cal factors. On an event scale, there is no temperature effect on the δ 18O values in the summer pre- cipitation, whereas the amount effect is shown to be clear. By tracing the moisture transport history and comparing the precipitation with its isotopic composition, it is shown that this amount effect not only reflects the change in moisture trajectory, which is related to the monsoon activities, but is also associated with the cooling degree of vapor in the cloud, the evaporation of falling raindrops and the isotopic exchange between the falling drops and the atmospheric vapor. As very little precipitation occurs in winter, the snow pack profile mainly represents the precipitation in the other three seasons. There are low precipitation δ 18O ratios in summer and high ratios in spring and autumn. The Meteoric Water Line (MLW) for the summer precipitation is δ D = 7.6 δ 18O + 13.3, which is similar to that at Delingha, located in the south rim of the Qilian Mountains. The MWL for the snow pack is δ D = 10.4 δ 18O + 41.4, showing a large slope and intercept. The deuterium excess (d) of the snow pack is positively correlated with δ 18O, indicating that both d and δ 18O decrease from spring to summer and increase from early autumn to early spring. This then results in the high slope and intercept of the MWL. Sea- sonal fluctuations of d in the snow pack indicate the change of moisture source and trajectory. During spring and autumn, the moisture originates from continental recycling or rapid evaporation over rela- tively warm water bodies like Black, Caspian and Aral Seas when the dry westerly air masses pass over them, hence very high d values in precipitation are formed. During summer, the monsoon is responsi- ble for the low d values. This indicates that the monsoon can reach the western part of the Qilian Mountains.ZHOU ShiQiao NAKAWO Masayoshi SAKAI Akiko MATSUDA Yoshihiro DUAN KeQin PU JianChen 2007Chinese Science Bulletin2007,52,21:21

6Blue-light-induced rapid chloroplast de-anchoring in Vallisneria epidermal cells显示文摘In the outer periclinal cytoplasm of leaf epidermal cells of an aquatic angiosperm Vallisneria, blue light induces'chloroplast de-anchoring', a rapid decline in the resistance of chloroplasts against centrifugal force. Chloroplast de-anchoring is known induced within 1 min of irradiation with high-fluence-rate blue light specifically, preceding the commencement of chloroplasts migration toward the anticlinal cytoplasm. However, its regulatory mechanism has remained elusive, although pharmacological analysis suggested that a calcium release from intracellular calcium stores is necessary for the response. In search of the responsible photoreceptors,immunoblotting analysis using antibodies against phototropins demonstrated that cross-reactive polypeptides of 120-k Da exist in the plasma-membrane fraction prepared from the leaves. In vitro phosphorylation analysis revealed that 120-k Da polypeptides were phosphorylated by exposure to blue light in a fluence-dependent manner. The blue-light-induced phosphorylation activity was sensitive to a Ser/Thr kinase inhibitor, staurosporine, and unusually was retained at a high level for a long time in darkness. Furthermore, phototropin gene homologs(Vallisneria PHOTOTROPIN1 and PHOTOTROPIN2)expressed in leaves were isolated. We propose that calcium-regulated chloroplast de-anchoring, possibly mediated by phototropins, is an initial process of the blue-light-induced avoidance response of chloroplasts in Vallisneria.Yuuki Sakai Shin-Ichiro Inoue Akiko Harada Ken-Ichiro Shimazaki Shingo Takagi 2015Journal of Integrative Plant Biology2015,57,1:1

17Cellular response against cytosolic leakage of mitochondrial DNA: insights into the pathology of Parkinson’s disease显示文摘Mitochondria are important organelles for cellular metabolism and homeostasis,and their abnormalities are implicated in various diseases.Since mitochondria originate from protobacterium,their components are easily recognized by pathogen sensors called pattern-recognition receptors as foreign substances in the cytoplasm.This is prominent for mitochondrial DNA(mtDNA)which has different properties from nuclear DNA,such as low,if any,methylation status,vulnerability to oxidation due to the proximity to the oxidative phosphorylation machinery,and its circular structure.Recent studies indicate that perturbations in mitochondrial function and homeostasis cause mtDNA to leak into the cytoplasm,where it triggers the innate immune response(West and Shadel,2017).Although inflammatory response is a cellular strategy to resist viral infections,it can also lead to undesirable outcomes by damaging own cells and tissues.Akiko Sakai Hideaki Matsui 2022Neural Regeneration Research2022,17,12:0
