miR-221/222 sponge abrogates tamoxifen resistance in ER-positive breast cancer cells through restoring the expression of ERα

open access: yesMolecular Biomedicine, 2021
Tamoxifen resistance (TamR) prevents ER-positive breast cancer patients from benefitting from endocrine therapy, and miR-221 or miR-222 plays vital roles in inducing TamR.

1-Quasiconformal Mappings and CR Mappings on Goursat Groups

open access: yesThe Scientific World Journal, 2014
We show that 1-quasiconformal mappings on Goursat groups are CR or anti-CR mappings. This can reduce the determination of 1-quasiconformal mappings to the determination of CR automorphisms of CR manifolds, which is a fundamental problem in the theory of ...

Analysis of the DD¯⁎K System with QCD Sum Rules

open access: yesAdvances in High Energy Physics, 2019
In this article, we construct the color singlet-singlet-singlet interpolating current with IJP=3/21- to study the DD¯⁎K system through QCD sum rules approach. In calculations, we consider the contributions of the vacuum condensates up to dimension-16 and

Hardy-Littlewood-Sobolev Inequalities on p-Adic Central Morrey Spaces

open access: yesJournal of Function Spaces, 2015
We establish the Hardy-Littlewood-Sobolev inequalities on p-adic central Morrey spaces. Furthermore, we obtain the λ-central BMO estimates for commutators of p-adic Riesz potential on p-adic central Morrey spaces.

L p $L^{p}$ and BMO bounds for weighted Hardy operators on the Heisenberg group

open access: yesJournal of Inequalities and Applications, 2016
In the setting of the Heisenberg group H n $\mathbb{H}^{n}$ , we characterize those nonnegative functions w defined on [ 0 , 1 ] $[0,1]$ for which the weighted Hardy operator H w $\mathsf{H}_{w}$ is bounded on L p ( H n ) $L^{p}(\mathbb{H}^{n})$ , 1 ≤ p ≤

Exponential Stabilizability of Switched Systems with Polytopic Uncertainties

open access: yesJournal of Applied Mathematics, 2012
The exponential stabilizability of switched nonlinear systems with polytopic uncertainties is explored by employing the methods of nonsmooth analysis and the minimum quadratic Lyapunov function.
