Nanowires (NWs) and self-assemble nanostructures made of chalcogenide semiconductor nanocrystals (NCs) are of great interests to the fundamental studies and practical applications. In this study, we reported a seeded-mediated growth of AgInS2 NWs and their intriguing self-assembly nanostructures with fingerprint-like shape. The key to the formation and self-assembly of AgInS2 NWs was the presence of In-S species that was a type of molecular metal chalcogenide complexes, serving as specific inorganic ligands for the growth of NWs and cross-linker molecules for the self-assembly of fingerprint-like nanostructures. Systematic studies were carried out to investigate the reaction factors, including the thermodynamics, amount and type of In precursors, and 1-dodecanethiol usage, to the success of the desired products.

宫颈癌是全世界女性最常见的妇科肿瘤,严重威胁女性健康。随着放疗等诊治技术的发展,宫颈癌已成为可治愈肿瘤。宫颈癌患者的生存期逐渐延长,患者治疗后生活质量也越来越受到关注,其中性生活质量是长期幸存者关注的最重要方面之一。但放疗对宫颈癌患者性生活质量的影响机制复杂,并且目前对预防及治疗宫颈癌患者放疗后性生活质量下降的处理方法没有统一标准。因此,本文就放疗对宫颈癌患者性生活质量的影响及处理方法进行综述。
To search naturally occurring interleukin-1β (IL-1β) inhibitors, biscaesalmins A (1) and B (2), two highly oxidized dimeric cassane diterpenoids with a newly formed alicyclic skeleton, have been isolated from the traditional Chinese medicine Kushilian (Ca
Surface-enhanced Raman scattering (SERS) is a powerful spectroscopic tool in quantitative analysis of molecules, where the substrate plays a critical role in determining the detection performance. Herein, a silver nanocubes/polyelectrolyte/gold film sandw
血尿是指尿液中带血的特定情况。血尿可以是肉眼可见的(肉眼血尿)或仅在显微镜下可见的(镜下血尿)。文献报道的无症状血尿发生率为1.7%~31.1%;一般临床工作中,血尿的发生率通常为4%~5%。甜菜类食物、一些带颜色的药物、部分月经出血或胃肠系统出血也可能混入尿液,使尿色变红。发生肌红蛋白尿(横纹肌溶解症)或血红蛋白尿(溶血)时,尿液也可以呈红色或黑色。
子宫内膜癌作为常见的女性生殖系统恶性肿瘤,近年来发病率逐渐升高,呈年轻化的发展趋势,严重威胁女性的身体健康。微小RNA(miRNA)是一类长度约为22个核苷酸的非编码单链RNA分子,由内源基因编码,它们调控动植物转录后的基因表达。近年来对于miRNA在肿瘤中的作用已成为研究热点,研究发现miRNA在肿瘤细胞增殖、凋亡、迁移、化学敏感性和放疗抗性中发挥重要的作用,子宫内膜癌中miRNA存在明显的差异性表达,因此miRNA有望成为子宫内膜癌诊断、治疗及判断预后的新靶标,本文对miRNA与子宫内膜癌的研究进展作
The catalysts of three-dimensionally ordered macroporous (3DOM) Al2O3-supported core-shell structured Pt@MnOx nanoparticles (3DOM-Pt@MnOx/Al2O3) were successfully prepared by the gas bubbling-assisted membrane reduction-precipitation (GBMR/P) method. Pt@M
The precise and real-time sensing of the temperature within the physiological range is of great significance in biology and medicine. Here, a Zn-based metal-organic framework (MOF) named Zn-TCOMA is synthesized with good SHG performance due to its unique
目的利用前列腺癌患者治疗前锥形束CT(CBCT)获取的内植标记物位移信息,量化盆腔区域骨骼对图像引导放疗(IGRT)造成的影响。方法对10例内植标记物前列腺癌患者进行治疗前CBCT扫描,记录标记物于左右(LR)、头脚(SI)、前后(AP)3个方向上的位移,利用算法量化盆腔区域骨骼对CBCT校准的影响。结果标记物于LR、SI、AP 3个方向上的位移平均值分别为0.51、1.33、1.36 mm;10例患者骨骼对校准影响量化指标误差均方根(RMS)于LR、SI、AP 3个方向上的平均值分别为0.02、0.06
