Upregulation of Circular RNA CircNFIB Attenuates Cardiac Fibrosis by Sponging miR-433

open access: yesFrontiers in Genetics, 2019
Cardiac fibrosis is the pathological consequence of fibroblast proliferation and fibroblast-to-myofibroblast transition. As a new class of endogenous non-coding RNAs, circular RNAs (circRNAs) have been identified in many cardiovascular diseases including

Periodic solutions of planar Hamiltonian systems with asymmetric nonlinearities

open access: yesBoundary Value Problems, 2017
In this paper, we look for periodic solutions of planar Hamiltonian systems { x ′ = f ( y ) + p 1 ( t , y ) , y ′ = − g ( x ) + p 2 ( t , x ) . $$\left \{ \textstyle\begin{array}{l} x'=f(y)+p_{1}(t,y),\\ y'=-g(x)+p_{2}(t,x).

Infinitely many singularities and denumerably many positive solutions for a second-order impulsive Neumann boundary value problem

open access: yesBoundary Value Problems, 2017
Using a fixed point theorem of cone expansion and compression of norm type and a new method to deal with the impulsive term, we prove that the second-order singular impulsive Neumann boundary value problem has denumerably many positive solutions ...

A First Implementation of Underwater Communications in Raw Water Using the 433 MHz Frequency Combined with a Bowtie Antenna

open access: yesItalian National Conference on Sensors, 2019
In 2016, there were 317 serious water pollution incidents in the UK, with 78,000 locations where businesses discharge controlled quantities of pollutants into rivers; therefore, continuous monitoring is vital. Since 1998, the environment agency has taken

LncRNA PCGEM1 accelerates non-small cell lung cancer progression via sponging miR-433-3p to upregulate WTAP

open access: yesBMC Pulmonary Medicine, 2020
Background Non-small cell lung cancer (NSCLC) is one of the most common malignant tumors all over the world. In recent years, long non-coding RNAs (lncRNAs) have been proven to participate in the development of different cancers, including NSCLC.

Existence and asymptotic expansion of the weak solution for a wave equation with nonlinear source containing nonlocal term

open access: yesBoundary Value Problems, 2017
In this paper, we consider the Robin problem for a wave equation with nonlinear source containing nonlocal term. Using the Faedo-Galerkin method and the linearization method for nonlinear term, the existence and uniqueness of a weak solution are proved ...
