Carbon steel is the most widely used metallic material in industry owing to its unique mechanical properties, availability, and low cost.1然而,当暴露于侵袭性环境(例如酸性溶液)时,碳钢的显着性较弱是其耐腐蚀性较差的耐腐蚀性,例如酸性溶液,这些溶液用于各种过程,例如清洁,腌制,淡化,下降和酸化。1,2 To prevent the corrosion of carbon steel, di ff erent methods have been used, including the use of corrosion inhibitors.Organic corrosion inhibitors showed good e ffi ciency and have great potential.3,4 However, their toxicity and envi- ronmental pollution are issues of great concern.The search for less toxic, environmentally friendly, and renewable corrosion inhibitors has become a research focus in this eld.5
简介:牛皮癣,由于表皮角质形成细胞与真皮和表皮的炎症结合而导致的慢性炎症性疾病。它在人群中的患病率较大,可能会影响0.5至11.4%的成年人。可以使用几种治疗方法来安抚这种疾病的症状,例如皮质类固醇局部选择,紫外线光疗和全身治疗,但尚无明确的治愈方法。但是,这些干预措施并不总是能够扭转状况并确保患者的生活质量,尤其是在更严重的情况下。使用治疗性单克隆抗体,通过抑制炎症剂(例如TNF,IL-23和IL-17)起作用,在改善这种病理学方面非常有前途。目的:分析免疫疗法治疗牛皮癣的生存力和有效性。方法:使用关键词“牛皮癣”,“治疗”和“免疫疗法”通过“ PubMed”平台进行了综合文献综述,从而根据Prisma协议选择了文章。在葡萄牙,英语和西班牙语中选择了文章,在过去5年中自由免费获得并发表。重复的文章被排除在研究的主题轴外。结果:7个选定的研究表明,在中度至重度牛皮癣治疗中使用免疫疗法的好处,包括改善的牛皮癣关节炎,30%的牛皮癣患者中存在并发症。结论:AS,使用了3种动物模型中的3种,通过诱发牛皮癣的皮肤症状在小鼠上或降低IL-23和IL-17水平来量化积极影响。The other 4 articles, outlined through clinical tests or retrospective studies with patients with the disease, which were treated through interleucine inhibitors already previously approved by FDA (Food and Drugs Administration), such as Adalimube, Guselkumab, Risankizumab and Tildrakizumab, and transcutaneous immunotherapy for RNAI showed control satisfactory psoriatic symptoms.The other 4 articles, outlined through clinical tests or retrospective studies with patients with the disease, which were treated through interleucine inhibitors already previously approved by FDA (Food and Drugs Administration), such as Adalimube, Guselkumab, Risankizumab and Tildrakizumab, and transcutaneous immunotherapy for RNAI showed control satisfactory psoriatic symptoms.
供应链管理是计划过程,执行和控制原材料的有效流动,工程中的工作清单,目标产品以及从初始消费点到消费点的相关信息流;因此,它影响组织,公司等的所有活动。因此,在与不确定性和风险的对抗中,必须关注行业和业务的机遇和威胁以及行业和公司权力的评估,供应链管理非常重要。本文具有描述性应用方法。Data analysis was based on analytical hierarchical process (AHP), and results of article showed that the risk of manufacturer is in the first rank as the most important risk of supply chain with 0.410 importance degree, then target customer risks with 0.269 importance degree, supplier risks with 0.212 importance degree, and finally distributor risks with 0.109 importance degree are in the second to fourth rank, respectively.
结果与讨论:通过野生型(WT)和TGP PSLOX2突变型线的DNA测序确定了稳定转基因PEA系(TGP)的成功CRISPR/CAS9介导的LOX基因编辑(TGP)。还评估了这些线路的LOX活性,PUFA水平和VOC。Compared to WT peas, the TGP lines showed a signi fi cant reduction (p < 0.05) in LOX activity and in the concentration of key VOCs, including hexanal, 2-hexenal, heptanal, (E)-2-heptenal, (E,E)-2,4- heptadienal, 1-octen-3-ol, octanal, (E)-2-octenal (E,E)-2,4-非二烯和Furan-2-苯基。在TGP浮动中,两个必需的PUFAS,亚油酸和二酚酸的含量是LOX的已知底物,表明CRISPRPR介导的基因编辑的效率在最小化其氧化和PUFAS及其产品的进一步调节方面具有效率。vocs的集合

NSP3(NSP3MD)的大域在甲虫病毒中高度保守,而Chikungunya病毒(CHIKV)NSP3MD的ADP-核糖基水合酶活性对于Chikv病毒复制和毒力至关重要。迄今已确定针对CHIKV NSP3的小分子药物。在这里,我们报告了与NSP3MD结合的小片段,这些片段实际上是通过筛选片段和X射线晶体学来解决的。这些鉴定出的片段具有相似的支架,2-吡啶酮-4-羧酸,并特别结合了NSP3MD的ADP-核糖结合位点。Among the fragments, 2-oxo-5,6-benzo- pyrimidine-4-carboxylic acid showed anti-CHIKV activity with an IC 50 of 23 μ M. Our frag- ment-based drug discovery approach provides valuable information to further develop a specific and potent nsP3 inhibitor of CHIKV viral replication based on the 2-pyrimidone-4- carboxylic acid scaffold.表明,这种嘧啶支架也可以与其他α病毒和冠状病毒的大域结合,因此具有潜在的抗病毒活性。

配对密度波(PDW)是一个长期以来的外来状态,没有外部磁场,具有振荡的超导顺序。到目前为止,在建立具有PDW远程顺序的2D微观模型以其基态建立了很少见。在这里,我们建议在蜂窝状晶格上分别使用最近的邻居(NN)和下一个neart-Neighbor(NNN)相互作用v 1和v 2的无旋转晶格模型中研究PDW超导性。By performing a state-of-the-art density-matrix renormalization group (DMRG) study of this t - V 1 - V 2 model at finite doping on six- leg and eight-leg honeycomb cylinders, we showed that the ground state exhibits PDW ordering (namely quasi-long-range order with a divergent PDW susceptibility).非常明显的是,这种PDW状态持续使用2D状的Fermi表面(FS)。据我们所知,这可能是具有2D样FS的系统中PDW的第一个受控数值证据。据我们所知,这可能是具有2D样FS的系统中PDW的第一个受控数值证据。
