Surface Sulfate Modification Promoted Excitons Extraction of BiOBr Nanosheets for Efficient 1O2 Photosynthesis and Chlorophenols Dechlorination

open access: yesRare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT Photocatalytic molecular oxygen (O2) activation provides a sustainable approach to produce singlet oxygen (1O2) for organic contaminants detoxification. However, the charge carriers‐involved pathway usually suffers from unsatisfactory 1O2 production efficiency owing to energy loss caused by photogenerated hole‐mediated superoxide species (•O2−

Chemical Stability of Ceftazidime Compounded in Saline, Glycerin and Dexamethasone‐SP Solutions Stored at −20°C, 4°C and 25°C Over a 60 Day Period

open access: yesVeterinary 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 ...

Sox9基因转染诱导L6大鼠成肌细胞向软骨细胞表型分化的研究

open access: yes四川大学学报. 自然科学版, 2011
利用脂质体转染法,将真核表达质粒pcDNA3.1-Sox9导入L6细胞中.通过细胞增殖检测、细胞形态学观察、标志基因表达分析和甲苯胺蓝染色等方法分析Sox9基因转染对L6细胞增殖和向成软骨方向分化的诱导作用.结果表明,Sox9基因转染对L6细胞的增殖能力没有影响,但能明显抑制L6细胞相互融合形成肌管.和对照相比,Sox9基因转染后,细胞成肌分化标志基因Myf5的表达受到明显抑制,而成软骨分化标志基因Ⅱ型胶原(typeⅡcollagen,Col2a1)和蛋白聚糖(Aggrecan,Agg)的表达显著提高 ...

多药耐药基因MDR1转染胎盘源间充质干细胞的研究

open access: yesZhongguo shiyan zhenduanxue, 2008
目的将全长外源多药耐药基因转入间充质干细胞使其外源基因得以表达。方法从胎盘组织中分离培养间充质干细胞,构建携带全长外源多药耐药基因的逆转录病毒,将此逆转录病毒转染间充质干细胞,绿色荧光显微镜检测外源基因的表达,western blot检测MDR1基因表达产物。结果绿色荧光显微镜可观测到转染后间充质干细胞有绿色荧光蛋白的表达,western blot检测到全长多药耐药基因编码的p-糖蛋白的表达。结论mdr1逆转录病毒载体可有效转染人胎盘源MSC,转染的外源基因可充分表达。

Uncovering the Nanozostera japonica species complex suggests cryptic speciation and underestimated seagrass diversity

open access: yesNew Phytologist, Volume 247, Issue 5, Page 2086-2097, September 2025.
Summary The importance of marine angiosperms, or seagrasses, as foundation species for marine coastal ecosystems is in marked contrast to their low species number of only 70 described taxa. Seagrass species tend to have very similar overall morphologies dictated by hydrodynamic forces of the ocean environment.
