| 1 | Regeneration performance and carbon consumption of semi-coke and activated coke for SO_2 and NO removal显示文摘To decrease the operating cost of flue gas purification technologies based on carbon-based materials, the adsorption and regeneration performance of low-price semi-coke and activated coke were compared for SO2 and NO removal in a simulated flue gas. The functional groups of the two adsorbents before and after regeneration were characterized by a Fourier transform infrared(FTIR) spectrometer, and were quantitatively assessed using temperature programmed desorption(TPD) coupled with FTIR and acid–base titration. The results show that semi-coke had higher adsorption capacity(16.2% for SO2 and 38.6% for NO) than activated coke because of its higher content of basic functional groups and lactones. After regeneration, the adsorption performance of semi-coke decreased because the number of active functional groups decreased and the micropores increased. Semi-coke had better regeneration performance than activated coke. Semi-coke had a larger SO2 recovery of 7.2% and smaller carbon consumption of 12% compared to activated coke. The semi-coke carbon-based adsorbent could be regenerated at lower temperatures to depress the carbon consumption, because the SO2 recovery was only reduced a small amount. | Song Ding Yuran Li Tingyu Zhu Yangyang Guo | 2015 | Journal of Environmental Sciences2015，27，8： | 17 |
| 2 | Epigenetic reprogramming, gene expression and in vitro development of porcine SCNT embryos are significantly improved by a histone deacetylase inhibitor--- m-carboxycinnamic acid bishydroxamide (CBHA)显示文摘施主原子核的不够的 epigenetic reprogramming 被相信是哺乳动物的体的房间的低发展效率的最重要的原因之一原子转移(SCNT ) 。以前的研究两个都显示出那在里面 vitro 并且在老鼠 SCNT 的 vivo 开发,胚胎能被处理与各种各样的 histone deacetylase 禁止者( HDACi )显著地增加包括 Trichostatin A , Scriptaid ,和 m-carboxycinnamic 酸 bishydroxamide ( CBHA ),在哪个仅仅 CBHA 的效果还没在另外的种类被测试了。在这份报纸,我们在猪的 SCNT 胚胎的发展检验 CBHA 处理的效果。我们发现了为 CBHA 处理的最佳剂量和时间:在激活以后为 24 h 与 2 mol/L CBHA 孵化 SCNT 胚胎能从 12.7% ~ 26.5% 增加胚囊率。Immunofluorescence 结果证明在 histone 的 acetylation 的水平 3 离氨酸 9 (AcH3K9 ) ,在 histone 的 acetylation 3 离氨酸 18 (AcH3K18 ) ,并且在 histone 的 acetylation 4 离氨酸(AcH4K16 ) 16 在 CBHA 处理以后被提起。同时, CBHA 处理改进了联系象 pou5f1, cdx2,和象 igf2 一样的印的基因那样的基因的开发的表达式。尽管有这些在 vitro 结果和 histone reprogramming 答应,完整的术语发展显著地没在处理以后被增加。在结论, CBHA 改善在里面猪 SCNT 胚胎的 vitro 开发,增加全球 histone acetylation 并且在早阶段改正一些发展地重要的基因的表示。作为在老鼠 SCNT,我们早在猪显示出那原子 epigenetic reprogramming SCNT 胚胎能被 CBHA 处理修改。 | Yuran Song Tang Hai Ying Wang Runfa Guo Wei Li Liu Wang Qi Zhou | 2014 | Protein & Cell2014，5，5： | 9 |
| 3 | Adsorption and desorption of SO_2, NO and chlorobenzene on activated carbon显示文摘Activated carbon(AC) is very effective for multi-pollutant removal; however, the complicated components in flue gas can influence each other's adsorption. A series of adsorption experiments for multicomponents, including SO_2, NO, chlorobenzene and H2 O,on AC were performed in a fixed-bed reactor. For single-component adsorption, the adsorption amount for chlorobenzene was larger than for SO_2 and NO on the AC. In the multi-component atmosphere, the adsorption amount decreased by 27.6% for chlorobenzene and decreased by 95.6% for NO, whereas it increased by a factor of two for SO_2,demonstrating that a complex atmosphere is unfavorable for chlorobenzene adsorption and inhibits NO adsorption. In contrast, it is very beneficial for SO_2 adsorption. The temperature-programmed desorption(TPD) results indicated that the binding strength between the gas adsorbates and the AC follows the order of SO_2> chlorobenzene > NO. The adsorption amount is independent of the binding strength. The presence of H2 O enhanced the component effects, while it weakened the binding force between the gas adsorbates and the AC. AC oxygen functional groups were analyzed using TPD and X-ray photoelectron spectroscopy(XPS) measurements. The results reveal the reason why the chlorobenzene adsorption is less affected by the presence of other components. Lactone groups partly transform into carbonyl and quinone groups after chlorobenzene desorption. The chlorobenzene adsorption increases the number of C = O groups, which explains the positive effect of chlorobenzene on SO_2 adsorption and the strong NO adsorption. | Yuran Li Yangyang Guo Tingyu Zhu Song Ding | 2016 | Journal of Environmental Sciences2016，28，5： | 8 |
| 4 | A direct spino-cortical circuit bypassing the thalamus modulates nociception显示文摘Nociceptive signals are usually transmitted to layer 4 neurons in somatosensory cortex via the spinothalamic-thalamocortical pathway.The layer 5 corticospinal neurons in sensorimotor cortex are reported to receive the output of neurons in superficial layers;and their descending axons innervate the spinal cord to regulate basic sensorimotor functions.Here,we show that a subset of layer 5 neurons receives spinal inputs through a direct spino-cortical circuit bypassing the thalamus,and thus define these neurons as spino-cortical recipient neurons(SCRNs).Morphological studies revealed that the branches from spinal ascending axons formed a kind of disciform structure with the descending axons from SCRNs in the basilar pontine nucleus(BPN).Electron microscopy and calcium imaging further confirmed that the axon terminals from spinal ascending neurons and SCRNs made functional synaptic contacts in the BPN,linking the ascending sensory pathway to the descending motor control pathway.Furthermore,behavioral tests indicated that the spino-cortical connection in the BPN was involved in nociceptive responses.In vivo calcium imaging showed that SCRNs responded to peripheral noxious stimuli faster than neighboring layer 4 cortical neurons in awake mice.Manipulating activities of SCRNs could modulate nociceptive behaviors.Therefore,this direct spino-cortical circuit represents a noncanonical pathway,allowing a fast sensory-motor transition of the brain in response to noxious stimuli. | Bing Cai Dan Wu Hong Xie Yan Chen Huadong Wang Sen Jin Yuran Song Anan Li Shiqi Huang Sashuang Wang Yingjin Lu Lan Bao Fuqiang Xu Hui Gong Changlin Li Xu Zhang | 2023 | Cell Research2023，33，10： | 0 |
| 5 | Targeting a cryptic allosteric site of SIRT6 with small-molecule inhibitors that inhibit the migration of pancreatic cancer cells显示文摘SIRT6 belongs to the conserved NAD^(+)-dependent deacetylase superfamily and mediates multiple biological and pathological processes.Targeting SIRT6 by allosteric modulators represents a novel direction for therapeutics,which can overcome the selectivity problem caused by the structural similarity of orthosteric sites among deacetylases.Here,developing a reversed allosteric strategy Allo Reverse,we identified a cryptic allosteric site,Pocket Z,which was only induced by the bi-directional allosteric signal triggered upon orthosteric binding of NAD^(+).Based on Pocket Z,we discovered an SIRT6 allosteric inhibitor named JYQ-42.JYQ-42 selectively targets SIRT6 among other histone deacetylases and effectively inhibits SIRT6 deacetylation,with an IC50 of 2.33μmol/L.JYQ-42 significantly suppresses SIRT6-mediated cancer cell migration and pro-inflammatory cytokine production.JYQ-42,to our knowledge,is the most potent and selective allosteric SIRT6 inhibitor.This study provides a novel strategy for allosteric drug design and will help in the challenging development of therapeutic agents that can selectively bind SIRT6. | Qiufen Zhang Yingyi Chen Duan Ni Zhimin Huang Jiacheng Wei Li Feng Jun-Cheng Su Yingqing Wei Shaobo Ning Xiuyan Yang Mingzhu Zhao Yuran Qiu Kun Song Zhengtian Yu Jianrong Xu Xinyi Li Houwen Lin Shaoyong Lu Jian Zhang | 2022 | Acta Pharmaceutica Sinica B2022，12，2： | 0 |
