Uracil base PCR implemented for reliable DNA walking.

PCR-based DNA walking is of efficacy for capturing unknown flanking genomic sequences. Here, an uracil base PCR (UB-PCR) with satisfying specificity has been devised for DNA walking. Primary UB-PCR replaces thymine base with uracil base, resulting in a primary PCR product composed of U-DNAs.

Probing Conformational Transition of TRPV5 Induced by Mechanical Force Using Coarse-Grained Molecular Dynamics.

Transient receptor potential vanilloid 5 (TRPV5) is a calcium-selective TRP channel that plays a crucial role in calcium homeostasis regulation. However, there are still many issues that need to be addressed, such as the specific conformational transition of TRPV5 and the specific functions of each structure in cation gating. Here, we build a model of the calcium ion transport protein from oocytes in the presence of the lipid membrane and water molecules.

A multi-parameter tunable plasmon modulator.

Multi-parameter control of light is a key functionality to modulate optical signals in photonic integrated circuits for various applications. However, the traditional optical modulators can only control one or two properties of light at the same time. Herein, we propose a hybrid structure which can modulate the amplitude, wavelength and phase of surface plasmon polaritons (SPPs) simultaneously to overcome these limitations.

A plasmon modulator by directly controlling the couple of photon and electron.

The manipulation of surface plasmon polaritons plays a pivotal role in plasmonic science and technology, however, the modulation efficiency of the traditional method suffers from the weak light-matter interaction. Herein, we propose a new method to overcome this obstacle by directly controlling the couple of photon and electron. In this paper, a hybrid graphene-dielectric- interdigital electrode structure is numerically and experimentally investigated.
