Zhongguo shiyan zhenduanxue, 2021 P物质（SP）是含有11个氨基酸的神经肽。研究表明,感觉神经通过释放SP等神经肽[1],参与皮肤炎症和创伤后修复[2]。软组织损伤刺激这些传入神经末梢释放SP,影响神经源性炎症和成纤维细胞增殖[3]。Nilsson等的研究发现增生性瘢痕中SP阳性神经纤维增多,提示SP可能参与了病理性瘢痕的形成[4]。本研究基于观察瘢痕疙瘩成纤维细胞源性SP对瘢痕疙瘩成纤维细胞外基质沉积的作用及对成纤维细胞迁移的影响,探讨其机制及相关治疗方案。

Study on the Gender Differences of College Graduates' Employment Migration [PDF]
, 2016 高校毕业生的就业流动不仅对高端人力资源的初次分配产生影响，而且对整个社会地域经济的发展以及毕业生个体在社会中的身份坐标和空间位置也会产生重要影响。随着高校规模扩张带来大学生就业难问题的凸显以及女性就业歧视问题的纷争，在大众传媒不断建构“女人味”流行文化的影响下，高校毕业生在就业流动中已形成泾渭分明的性别阶层差异现象，成为值得深思和研究的社会问题。通过强化性别平权意识并辅以相应的政策举措，既有利于高端人力资源的合理配置，也有助于社会公平与两性关系的和谐发展。 本研究以“性别”作为贯穿全文的基本线索 ...

Rare Metals, EarlyView.ABSTRACT Intervertebral disc degeneration (IDD) is a predominant cause of low back pain, significantly impacting quality of life. Mitochondrial fitness is essential in the progression of IDD, as it regulates cellular senescence and pyroptosis. This study investigates the role of mitochondrial caseinolytic protease P (ClpP) in alleviating senescence and

Rare Metals, EarlyView.ABSTRACT Ni3S2 has emerged as a promising catalyst for the electrochemical oxidation of biomass‐derived 5‐hydroxymethylfurfural (HMF) to 2,5‐furandicarboxylic acid (FDCA), driven by its distinctive physicochemical properties. However, its practical catalytic efficiency is severely hindered by abundant electrochemically inactive surface sites and poor ...

Rare Metals, EarlyView.ABSTRACT Chlorination roasting has emerged as a promising pyrometallurgical strategy for the selective recovery of lithium from spent lithium‐ion batteries (LIBs). In this study, a natural roasting agent, seawater‐derived chlorides, was employed to selectively extract lithium from spent LiNi0.5Co0.2Mn0.3O2 (NCM523) cathode. MgCl2·6H2O, a main component
