超声介导微泡破裂法对VEGF体外转染成纤维细胞蛋白表达影响的实验研究
Zhongguo shiyan zhenduanxue, 2008 目的利用ELISA检测法观察诊断剂量的超声介导微泡破裂法对VEGF体外转染成纤维细胞蛋白表达的影响并探讨该种转染方法的最佳超声条件。方法实验分组:单纯VEGF质粒转染组;超声+造影剂微泡+VEGF质粒转染组,该组并根据MI（机械指数）分为三组1.2;1.4;1.6。转染后利用ELISA法对各组成纤维细胞的VEGF蛋白表达进行定量检测;利用锥虫蓝染色法比较不同超声强度对细胞活性的影响。结果VEGF质粒转染成纤维细胞后,24h开始即有较高水平的VEGF蛋白表达,表达量于48 h7、2 h呈下降趋势;超声 ...

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT The electrocatalytic reduction of nitrate (NO3ER) has emerged as a promising strategy for mitigating NO3− ${{\text{NO}}_{3}}^{-}$ pollution in wastewater while concurrently producing value‐added ammonia; however, its process is significantly hindered by the lack of highly efficient and low‐cost electrocatalysts. Herein, we proposed several non‐

Veterinary Dermatology, Volume 36, Issue 6, Page 862-869, December 2025.ABSTRACT Background Chronic cases of canine otitis externa (OE) often develop infections with Pseudomonas aeruginosa (PA). Given the organism's high level of resistance, veterinary surgeons often turn to compounded solutions. Limited data describing the stability and potency of compounded ceftazidime (CAZ) solutions are available, which may affect ...
