Camptothecin (CPT), a plant alkaloid originally isolated from the native Chinese tree, Camptotheca acuminate, exerts the toxic effect by targeting eukaryotic DNA topoisomerase 1 (DNA Topo1). Besides as potent anti-cancer agents, CPT and its derivatives are now being explored as potential pesticides for insect control. In this study, we assessed their… (More)
BACKGROUND In recent years, concerns over the potential impact of synthetic pesticides on the environment have made the discovery and development of environmentally friendly pesticides a more pressing issue. Camptothecin (CPT) and its derivatives have attracted much attention owing to their unique mechanisms of action against insects. In this paper, two… (More)
The paper presents a detailed calculation of characteristic of five different topology permanent magnet machines for high performance traction including hybrid -electric vehicles using finite element analysis (FEA) method. These machines include V-shape single layer interior PM, W-shape single-layer interior PM, Segment interior PM and surface PM on the… (More)
Both analysis and numerical calculations have been carried out to investigate the relationship between Young’s modulus and nonideally sharp indentation parameters. The results confirm that there exists an approximate one-to-one correspondence between the ratio of nominal hardness/reduced Young’s modulus (Hn/Er) and the ratio of elastic work/total work… (More)
Nanopores have been used as a high throughput tool for characterizing individual biomolecules and nanoparticles. Here, we present the translocation of rigid rod-shaped tobacco mosaic virus (TMV) through solid-state nanopores. Interestingly, due to the high rigidity of TMV, three types of events with distinctive characteristics at the capture process and a… (More)
Flexible branched primers were designed to construct stable gene nanoparticles with multiple target gene copies through polymerase chain reaction, which can be used as an efficient transcription template in eukaryotic cells for gene delivery.
RNA interference (RNAi) is a cellular process for gene silencing. Because of poor serum stability, transferring dsRNA directly into the target cells is a challenge. We report a facile and universal strategy to construct short hairpin RNA (shRNA) transcription nanoparticles with multiple shRNA transcription templates by PCR with flexible branched primers… (More)
We report here a site-specific terminal dual-labeling strategy for a transcribed RNA. The combination of 5'-thiophosphoryl and 3'-amino functionalities enables efficient RNA dual labeling with different fluorophores at both 5'- and 3'-terminal positions specifically. This dual-labeling strategy is applied to pre-miRNA for construction of molecular beacons.… (More)
Brucea javanica (L.) Merr. is a medicine plant distributed widely throughout Asia where its bitter fruits have been used traditionally in medicine for treating various ailments and controlling some pests. In recent years, concerns over the potential impact of synthetic pesticides on human health and environment have now become more pressing to develop… (More)
Virus-like assemblies with controllable size and surface groups can be used as efficient templates for the controllable synthesis of CdS nanorods, which represents a new strategy for controllable preparation of one-dimensional (1D) organic-inorganic nanocomposites.
