This paper presents a reconfigurable RF front-end for multi-mode multi-standard(MMMS) applications. The designed RF front-end is fabricated in 0.18 μm RF CMOS technology. The low noise characteristic is achieved by the noise canceling technique while the bandwidth is enhanced by gate inductive peaking technique. Measurement results show that, while the input frequency ranges from 100 MHz to 2.9 GHz, the proposed reconfigurable RF front-end achieves a controllable voltage conversion gain(VCG) from 18 dB to 39 dB. The measured maximum input third intercept point(IIP3) is-4.9 dBm and the minimum noise figure(NF) is 4.6 dB. The consumed current ranges from 16 mA to 26.5 mA from a 1.8 V supply voltage. The chip occupies an area of 1.17 mm^2 including pads.

Simulating annealing algorithm was used in docking computation to predict a selected peptide VYMSPF(P2) binding site on the ectodomain of FGFR1. The peptide is located on the hydrophobic surface of the receptor, which is critical for FGF binding. The synthesized peptide can effectively inhibit the mitogenic activity of aFGF, and has a potential to become a therapeutic agent as an aFGF antagonist.

背景:传统的骨组织工程技术治疗临界骨缺损存在成骨效率低、安全性差等问题。而以非病毒纳米粒子为基因载体构建的基因强化型骨组织工程移植物,具有更高的成骨效率和安全性,引起了国内外学者的广泛关注和研究。目的:对当前国内外有关纳米粒子在组织工程成骨基因治疗研究中取得的新技术、新方法以及面临的挑战等进行综述,旨在为纳米粒子介导的骨组织工程基因治疗研究提供参考。方法:第一作者在Pub Med、Web of Science和中国知网数据库上进行文献检索,并以“Bone defect repair,Bone tissue engineering,Gene delivery,Nanoparticles,Non-viral gene vector,Sustained release technology,Sequential release,Targeted delivery”作为英文检索词,以“骨缺损修复,骨组织工程,基因递送,纳米粒子,非病毒基因载体,缓释技术,序贯释放,靶向递送”作为中文检索词,最终纳入84篇文献进行总结。结果与结论:(1)在骨缺损愈合的各个生理阶段进行针对性的基因递送可以显著增强骨修复效果。在早期炎症阶段,通过纳米粒子递送抗炎基因来调节炎症反应,可以为后续骨愈合奠定基础;在血管新生期,向局部递送促血管化基因有助于形成高度组织化、可灌注的血管系统,加快骨愈合速度;随着血管化的进行,骨骼的神经再支配也开始发生,此时递送促神经再生的功能性基因有利于促进神经化骨再生;在成骨阶段,通过构建纳米粒子-成骨基因复合物,可以直接提升支架及体内新骨形成的效率。(2)各种有机、无机纳米颗粒、金属有机框架和外泌体等非病毒纳米载体,在骨组织工程基因治疗中具有巨大的潜力,这些纳米基因载体各有其独特的优势和不足,因此在实际应用时,需要根据基因转染效率、生物安全性和成骨特性等因素选择最合适的类型。(3)为了全面提升递送基因的效果,目前主要通过对纳米载体进行各种功能设计来增强基因转染效率,包括增强缓释性和多基因递送序贯性等时间调控能力、增强对骨组织和成骨相关细胞的空间靶向能力、增强跨膜运输效率和细胞核靶向能力等全过程调控手段。(4)未来要进一步推动纳米粒子介导的骨组织工程基因治疗在临床上的应用,还需要克服诸多技术挑战,包括提高有机纳米基因载体的基因转染效率、降低无机纳米载体的生物安全性风险、优化新型纳米载体的生产工艺以及促进其它生理过程与成骨交互作用等,这些问题也是未来骨组织工程基因治疗的研究热点和潮流。

Cuticular wax forms a hydrophobic barrier on aerial plant organs; it plays an important role in protecting a plant from damage caused by many forms of environmental stress. In the present study, we characterized a rice leaf wax-deficient mutant osgll-1 derived from a spontaneous mutation, which exhibited a wax-deficient and highly hydro- philic leaf phenotype. We cloned the OsGli-1 gene by the map-based cloning method and performed a complementation test to confirm the function of the candidate gene. Molecular studies revealed that OsGli-1 was a member of the OsGL1 family, and contained regions that were homologous to some regions in sterol desaturases and short-chain dehydro- genases/reductases. Compared to the wild-type, the osgll-1 mutant showed decreased cuticular wax deposition, thinner cuticular membrane, decreased chlorophyll leaching, increased rate of water loss, and enhanced sensitivity to drought. OsGL 1-1 is expressed ubiquitously in rice. The transient expression of OsGLl-l-green fluorescent protein fusion protein indicated that OsGli-1 is localized in the cytoplasm, plasma membrane, and nucleus.
