Two antiparellel beta-strands (B1 and B2) in close proximity to C93 and C310 are masked in the internal structure. In rested cells, APE1 resides in the nucleus due to the existence of NLS. Upon nitrosative stress, S-nitrosation of C93 and C310 contributes to unmasking of the B1 and/or B2 by changing conformation, which may facilitate the nuclear export of APE1 in a CRM1-independet manner (perhaps mediated by an unknown transport protein). At the same time, importin-dependent nuclear import pathway is repressed by NO insult, which may prevent the already exported cytosolic APE1 from re-import into the nucleus. However, once the intracellular environment becomes reductive (e.g. the increased reducing molecules such as DTT), both NO-elicited S-nitrosation of APE1 and NO-caused repression of importin can be abrogated; thus, the inducible nuclear export of APE1 by NO could be prevented or reversed

    Three silicon and nitrogen-centered cyanate monomers tetrakis­(4-cyanatophenyl)­silane, tetrakis­(4-cyanatobiphenyl)­silane, and tris­(4-cyanatobiphenyl)­amine were designed and synthesized, which were then polymerized via thermal cyclotrimerization reaction to create highly porous cyanate resin networks with systematically varied nodes and linking struts. The chemical structures of monomers and polymers were confirmed by <sup>1</sup>H NMR, FTIR, solid-state <sup>13</sup>C CP/MAS NMR spectra, and elemental analysis. The products are amorphous with 5% weight-loss temperatures over 428 °C. The results based on N<sub>2</sub> and CO<sub>2</sub> adsorption isotherms show that the pores in these polymers mainly locate in the microporous region, and the BET surface areas are up to 960 m<sup>2</sup> g<sup>–1</sup>, which is the highest value for the porous cyanate resin reported to date. The nitrogen- and oxygen-rich characteristics of cyanate resins lead to the networks strong affinity for CO<sub>2</sub> and thereby high CO<sub>2</sub> adsorption capacity of 11.1 wt % at 273 K and 1.0 bar. The adsorption behaviors of H<sub>2</sub>, CO<sub>2</sub>, benzene, <i>n</i>-hexane, and water vapors were investigated by correlating with the chemical composition and porosity parameters of the networks as well as the physicochemical nature of adsorbates

    Table1_Service scheduling strategy for microservice and heterogeneous multi-cores-based edge computing apparatus in smart girds with high renewable energy penetration.DOCX

    The microservice-based smart grid service (SGS) organization and the heterogeneous multi-cores-based computing resource supply are the development direction of edge computing in smart grid with high penetration of renewable energy sources and high market-oriented. However, their application also challenges the service schedule for edge computing apparatus (ECA), the physical carrier of edge computing. In the traditional scheduling strategy of SGS, an SGS usually corresponds to an independent application or component, and the heterogeneous multi-core computing environment is also not considered, making it difficult to cope with the above challenges. In this paper, we propose an SGS scheduling strategy for the ECA. Specifically, we first present an SGS scheduling framework of ECA and give the essential element of meeting SGS scheduling. Then, considering the deadline and importance attributes of the SGS, a microservice scheduling prioritizing module is proposed. On this basis, the inset-based method is used to allocate the microservice task to the heterogeneous multi-cores to utilize computing resources and reduce the service response time efficiently. Furthermore, we design the scheduling unit dividing module to balance the delay requirement between the service with early arrival time and the service with high importance in high concurrency scenarios. An emergency mechanism (EM) is also presented for the timely completion of urgent SGSs. Finally, the effectiveness of the proposed service scheduling strategy is verified in a typical SGS scenario in the smart distribution transformer area.</p

    No full text
    Immune checkpoint inhibitor (ICI) is an up-to-date therapy for cancer with a promising efficacy, but it may cause unique immune-related adverse events (irAEs). Although irAEs could affect any organ, irAEs-induced whole urinary tract expansion was rarely reported. Herein, we reported a 27-year-old male patient with thymic carcinoma who received the treatment of tislelizumab, paclitaxel albumin and carboplatin. He was hospitalized for severe bellyache and lumbago after 6 courses of treatment. Antibiotic and antispasmodic treatment did not relieve his symptoms. The imaging examinations reported whole urinary tract expansion and cystitis. Therefore, we proposed that the patient’s pain was caused by tislelizumab-induced ureteritis/cystitis. After the discontinuation of tislelizumab and the administration of methylprednisolone, his symptoms were markedly alleviated. Herein, we reported a rare case of ICI-induced ureteritis/cystitis in the treatment of thymic cancer and reviewed other cases of immunotherapy-related cystitis and tislelizumab-related adverse events, which will provide a reference for the diagnosis and treatment of ICI-related irAEs.</p
