Dual‐Bioactive Lignin‐Based Microcarrier Hydrogel Platform via Metal Salt Crosslinking for Synchronized Infection Eradication and Bone Regeneration

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Infected bone defects represent a dual therapeutic challenge demanding concurrent infection inhibition and osteogenesis promotion. Systemic antibiotic administration is taken as a classical treatment protocol but often yields inadequate local antibiotic concentrations and delayed bone repair.

阳离子脂质体基因载体的细胞转染研究

open access: yes, 2009
研究阳离子脂质体在不同细胞中的转染效率及毒性。首先采用DNA延滞实验研究Lipofectamine2000、DOTAP转染试剂与DNA的结合能力。然后选用绿色荧光蛋白的质粒pGFP-N2作为报告基因模型和转染试剂制成复合物后转染Hela、7721、HT29细胞,比较多种因素对转染的影响。最后使用MTT比色法分析Lipofectamine2000、DOTAP转染试剂对细胞的毒性。随着复合物中转染试剂比例的增加,Lipofectamine2000、DOTAP与DNA结合能力逐渐增强 ...

外源性表达VEGF165b对人膀胱癌裸鼠移植瘤生长影响的研究

open access: yesZhongguo shiyan zhenduanxue, 2014
目的建立人膀胱癌T24细胞裸鼠移植瘤模型,探讨外源性表达VEGF165b对其生长的影响及其机制。方法分别移植未转染和转染VEGF165b表达载体的人膀胱癌T24细胞到裸鼠膀胱内,28d使处死动物,称量肿瘤重量,测定肿瘤体积。Western blot法检测肿瘤VEGF165b、p-VEGFR2、AKT、p-AKT蛋白表达。结果转染pcDNA-VEGF165b组肿瘤重量和体积与未转染组和转染pcDNA3.0组相比明显降低(P0.05)。Western blot结果显示,转染pcDNA ...

Millimeter/Nano‐Structured Metal Monolithic Catalysts: A Privileged Opportunity for Sustainable Water Purification

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Cross‐scale assembly of metal (sub) nanoparticles and/or single atoms into millimeter/nanostructured metal monolithic catalysts (Min‐SMCs) is highly appealing for sustainable water cleanup, due to energy‐efficient catalyst recyclability, high infrastructure compatibility, and low metal‐releasing risks.
