人嗅黏膜神经干细胞是新近发现的可用于神经精神疾病研究的良好材料,同时,抗抑郁治疗促进脑部神经干细胞增殖及向神经细胞转化。然而,嗅黏膜神经干细胞体外培养方法及抗抑郁药对其增殖及神经发生的影响尚不清楚。该研究采用组织块培养获取嗅细胞,神经球培养法纯化神经干细胞,Nestin免疫荧光验证神经干细胞特异性。加入促神经分化培养基诱导神经干细胞向神经细胞分化,MAP2(microtubule associated protein 2)、TUJ1(β3-tubulin)免疫荧光验证神经细胞特异性。采用CCK-8和蛋白质分子印记技术分别检测抗抑郁药对嗅黏膜神经干细胞增殖及分化的影响。结果显示,体外培养嗅黏膜神经干细胞呈球状聚集;Nestin、MAP2、TUJ1免疫荧光阳性;抗抑郁药促进嗅黏膜神经干细胞增殖、促进其向神经细胞转化,TUJ1表达上升。综上所述,抗郁药能够促进神经干细胞增殖及神经发生,可能为其抗抑郁治疗的机制之一。

Photoactive complexes of nonprecious transition metals, mainly including those in the first-row and partially the second-row of the Periodic table of elements, have received increasing attention in view of their low cost and long-term sustainability. They are recognized as promising alternatives to noble transition metal complex congeners that have been extensively studied in optoelectronic devices, artificial photosynthesis, photocatalysis, biodiagnostics, and therapeutics, etc. This review is devoted to a comprehensive summary on the classical and recent advances on photoactive nonprecious transition metal complexes, including photoactive Zr, V, Cr, Mo, and W complexes, Mn complexes and hybrids, Fe, Co, Ni, and Cu complexes, and Zn and Cd complexes and hybrids. A particular focus is given on the molecular design, modulation of photophysical and photochemical properties, and applications of the representative and lately-developed nonprecious metal complexes. In addition, a perspective on the future development in this field is provided at the end of this review.

Low-Temperature Fabrication of Stable Black-Phase CsPbI₃ Perovskite Flexible Photodetectors Toward Wearable Health Monitoring

Low-temperature fabrication of black-phase CsPbI3 perovskite films is first demonstrated by using diphenylphosphinic chloride additive under 30-50 degrees C, arising from the steric effect and chloride insertion ***-area high-quality all-inorganic perovskite films with fewer defects enhanced crystallographic orientation, and excellent environmental stability is *** record performances are demonstrated for flexible wearable photodetectors with a responsivity of 42.1 A W-1, a detectivity of 1.3 x 1014 Jones, high-fidelity image, photoplethysmography sensor functions, and high mechanical stability. Flexible wearable optoelectronic devices fabricated from organic-inorganic hybrid perovskites significantly accelerate the development of portable energy, biomedicine, and sensing fields, but their poor thermal stability hinders further applications. Conversely, all-inorganic perovskites possess excellent thermal stability, but black-phase all-inorganic perovskite film usually requires high-temperature annealing steps, which increases energy consumption and is not conducive to the fabrication of flexible wearable devices. In this work, an unprecedented low-temperature fabrication of stable black-phase CsPbI3 perovskite films is demonstrated by the in situ hydrolysis reaction of diphenylphosphinic chloride additive. The released diphenyl phosphate and chloride ions during the hydrolysis reaction significantly lower the phase transition temperature and effectively passivate the defects in the perovskite films, yielding high-performance photodetectors with a responsivity of 42.1 A W-1 and a detectivity of 1.3 x 1014 Jones. Furthermore, high-fidelity image and photoplethysmography sensors are demonstrated based on the fabricated flexible wearable photodetectors. This work provides a new perspective for the low-temperature fabrication of large-area all-inorganic perovskite flexible optoelectronic devices.

目的:研究Prohibitin对非小细胞肺癌株A549和NCI-H460细胞增殖和凋亡的影响。方法:将针对Prohibitin的特异性的干扰片段瞬时转染非小细胞肺癌A549和NCI-H460细胞株,以瞬时转染与Prohibitin没有同源性的干扰片段的细胞作为阴性对照,通过免疫蛋白印迹检测各组细胞Prohibitin和Survivin蛋白的表达情况,通过MTT法检测各组细胞的增殖情况,通过流式仪检测各组细胞的凋亡率。结果:针对Prohibitin基因设计的siRNA片段特异性地沉默该基因的表达,与对照组相比较,干扰组的细胞的增殖活性明显增强。同时与凋亡密切相关的Survivin的表达在沉默掉prohibitin后,在A549和NCI-H460中分别降低了46.3%和54.5%。而干扰prohibitin后导致A549细胞的凋亡率上升了约2%。结论:Prohibitin能显著抑制非小细胞肺癌A549和NCI-H460细胞的增殖,而对凋亡的影响可能并不是通过survivin介导的。
