Down-regulation of Kv4.3 K⁺ channels commonly occurs in multiple diseases, but the understanding of the regulation of Kv4.3 K⁺ channels and the role of Kv4.3 K⁺ channels in pathological conditions are limited. HEK (human embryonic kidney)-293T cells are derived from HEK-293 cells which are transformed by expression of the large T-antigen. In the present(More)
Rare-earth-based nanomaterials have recently drawn considerable attention because of their unique energy upconversion (UC) capabilities. However, studies of Sc(3+)-based nanomaterials are still absent. Herein we report the synthesis and fine control of Na(x)ScF(3+x) nanocrystals by tuning of the ratio of oleic acid (OA, polar surfactant) to 1-octadecene(More)
For the first time, we have synthesized orthorhombic phase KSc2F7:20%Yb/2%Er (KSc2F7:Yb/Er) nanorods and further studied the crystal structure and morphology evolution, as well as their upconversion (UC) properties under varying F(-) contents and reaction temperatures. Different from β-NaYF4:20%Yb/2%Er (NaYF4:Yb/Er) nanorods that usually give strong green(More)
We introduce gold nanorods (GNRs) decoration on NaYF4:Yb/Tm upconversion nanocrystals (UCNCs) by functionalizing the UCNCs with polyamidoamine generation 1 (PAMAM G1) dendrimer, followed by a single-step seed-mediated growth of long-range GNRs to enhance "biological window" upconversion emission. The up-conversion emission of GNR-decorated UCNCs can be(More)
HIV-infected patients have a high prevalence of long QT syndrome (LQTs). hERG K(+) channel encoded by human ether-a-go-go related gene contributes to IKr K(+) currents responsible for the repolarization of cardiomyocytes. Inhibition of hERG K(+) channels leads to LQTs. HIV Tat protein, the virus transactivator protein, plays a pivotal role in AIDS. The aim(More)
Synthesis, structure, and physical properties of a novel 11-methylbenzo[d]pyreno[4,5-b]furan (BPF) and its self-assembly in water have been reported. The performance of nanowire-based films in organic light-emitting diodes is much better than that of the thin film deposited by directly drop-coating BPF molecules in THF solution. SEM study indicates that the(More)
Compared with automatic speech recognition (ASR), the human auditory system is more adept at handling noise-adverse situations, including environmental noise and channel distortion. To mimic this adeptness, auditory models have been widely incorporated in ASR systems to improve their robustness. This paper proposes a novel auditory model which incorporates(More)
Synthesis of lanthanide-doped upconversion nanocrystals (LDUNs) with controlled morphology and luminescence has long been desired in order to fulfill various application requirements. In this work, we have investigated the effect of the NaF : Ln(3+) molar ratio, in the range of 1 to 20, on the morphology, crystal structure, and upconversion properties of(More)
A novel [2]pseudorotaxane was successfully constructed by the complexation of dibenzo[24]-crown-8 (DB24C8) derivative bearing terpyridine moiety (1) with lanthanide ion (Tb(3+)) and fullerene-containing ammonium salt (2), exhibiting the controlled photophysical behaviors as a reversible luminescent lanthanide switch in the presence of K(+) or 18-crown-6(More)
