Applying the timing tools of kilohertz quasi-periodic oscillations(k Hz QpOs)and cross-correlations,we study the influence of the magnetosphere-disk relation on the X-ray radiation process of GX 17+***,as the spectral state track of X-ray emission evolves along the horizontal branch(HB),the magnetosphere-disk radii of the source derived by k Hz QpOs shrink from r~24 km to r~18 km,while its average X-ray intensities in≤10 ke V and in≥10 ke V show the opposite evolutional ***,this branch has been detected with the anti-correlations between the low-/high-energy(e.g.,2–5 ke V/16–30 ke V)*** suggest that in HB there may exist an X-ray radiation transfer process at the disk radii near the neutron star(NS),i.e.,~5–10 km away from the surface,which probably originates from the interaction between the corona or jet with high-energy X-rays and accretion disk with low-energy ***,as the source evolves along the normal branch(NB)and along the flaring branch(FB),their average X-ray intensities in all~2–30 ke V show the monotonously decreasing and monotonously increasing trends,*** addition,these two branches are both dominated by the positive correlations between the low-and high-energy(e.g.,2–5 ke V/16–30 ke V)***,the evolution along NB is accompanied by the shrinking of the magnetosphere-disk radii from r~18 km to r~16 *** ascribe these phenomena to that as the shrinking of the accretion disk radius,the piled up accretion matter around the NS surface may trigger the radiation that produces both the low-and high-energy X-rays simultaneously,and then form the branches of NB and FB.

N Mineralization as Affected by Long-Term N Fertilization and Its Relationship with Crop N Uptake

引用

pedosphere 2006年第1期16卷 125-130页

作者： YAN de-Zhi WANG de-Jian SUN Rui-juan LIN Jing-Hui Institute of Soil Science Chinese Academy of Sciences Nanjing 210008 （China）. Graduate -School of the Chinese Academy of Sciences Beijing 100039 （China）

A field experiment established in 1997 was conducted to study the effect of long-term N fertilizer application on N mineralization in a paddy soil determined using a laboratory anaerobic incubation followed with a field incubation and to measure the relationship between in situ N mineralization and crop N uptake. To estimate N mineralization in the laboratory, soil samples were collected from plots with N application at different rates for six years and were incubated. Soils treated with fertilizer N mineralized more N than unfertilized soils and mineralization increased with N application rates. Also, the fraction of total N mineralized increased with increasing N fertilizer application. These findings meant that a substantial portion of previously applied N could be recovered slowly over time in subsequent crops. The field incubation of the plot receiving no fertilizer N showed that the NH4^＋-N concentration varied greatly during the rice-growing season and seasonal changes of N mineralization were due more to accumulation of NH4^＋-N than NO3^-N. Hice N uptake increased up to a maximum of 82 kg N ha^-1 during the season. The close agreement found between in situ N mineralization and rice N uptake suggested that the measurement of in situ N mineralization could provide useful recommendations for adequate fertilizer N application.

Downregulation of signal transduction and STAT3 expression exacerbates oxidative stress mediated by NLRp3 inflammasome

引用

Neural Regeneration Research 2018年第12期13卷 2147-2155页

作者： Hua Bai Qi-Fang Zhang juan-juan Duan de-Jun Yu Li-Jie Liu Medical Laboratory Center Third Affiliated Hospital Guizhou Medical University department of Neurology Third Affiliated Hospital Guizhou Medical University Key Laboratory of Endemic and Ethnic Diseases of Ministry of Education and Key Laboratory of Medical Molecular Biology Guizhou Medical University

Activated nucleotide binding to the oligonucleotide receptor protein 3（NLRp3） inflammasome is possibly involved in the pathogenesis of Alzheimer＇s disease through oxidative stress and neurogenic inflammation. Low expression of the signal transducer and activator of transcription 3（STAT3） gene may promote the occurrence of neurodegenerative diseases to some extent. To clarify the roles of the NLRp3 inflammasome and STAT3 expression in oxidative stress,（1） SHSY5 Y cells were incubated with 1 mM H2 O2 to induce oxidative stress injury, and the expression of human-cell-specific signal transduction, STAT3-shRNA silencing signal transduction and STAT3 were detected. Cells were pretreated with Ca2＋ chelator BApATA-AM（0.1 mM） for 30 minutes as a control.（2） Western blot assay was used to analyze the expression of caspase-1, NLRp3, signal transduction and STAT3. Enzyme-linked immunosorbent assay was used to analyze interleukin-1β levels. Flow cytometry was carried out to calculate the number of apoptotic cells. We found that H2 O2 treatment activated NLRp3 inflammasomes and decreased phosphorylation of signal transduction and STAT3 serine 727. BApTA-AM pretreatment abolished the H2 O2-induced activation of NLRp3 inflammasomes, caspase-1 expression, interleukin-1β expression and apoptosis in SHSY5 Y cells, and had no effect in cells with downregulated STAT3 expression by RNAi. The findings suggest that downregulation of signal transduction and STAT3 expression may enhance the oxidative stress mediated by NLRp3, which may not depend on the Ca2^＋ signaling pathway.
