Cytoplasmic p21 promotes stemness of colon cancer cells via activation of the NFκB pathway

Molecular Oncology, EarlyView.
Cytoplasmic p21 promotes colorectal cancer stem cell (CSC) features by destabilizing the NFκB–IκB complex, activating NFκB signaling, and upregulating BCL‐xL and COX2. In contrast to nuclear p21, cytoplasmic p21 enhances spheroid formation and stemness transcription factor CD133.

Almost-periodic solution for BAM neural networks [PDF]

Surveys in Mathematics and its Applications, 2009
In this paper, we study the existence and uniqueness solution and investigate the conditions that make it almost-periodic solution for BAM neural networks with retarded delays.

Some New Exact Solutions of (1+2)-Dimensional Sine-Gordon Equation

Abstract and Applied Analysis, 2014
We use a generalized tanh function expansion method and a direct method to study the analytical solutions of the (1+2)-dimensional sine Gordon (2DsG) equation.

PERIODIC SOLUTIONS AND SLOW MANIFOLDS [PDF]

International Journal of Bifurcation and Chaos, 2007
After reviewing a number of results from geometric singular perturbation theory, we give an example of a theorem for periodic solutions in a slow manifold. This is illustrated by examples involving the van der Pol-equation and a modified logistic equation.

European Code Against Cancer, 5th edition – hormone replacement therapy, other common medical therapies and cancer

Molecular Oncology, EarlyView.
The 5th edition of the European Code Against Cancer (ECAC5) contains 14 recommendations on cancer prevention. Here, we update the cancer prevention recommendations regarding the use of hormone replacement therapy (HRT), which is positioned as recommendation number 13 of the ECAC5.

Positive periodic solutions for second-order neutral differential equations with functional delay

Electronic Journal of Differential Equations, 2012
We use Krasnoselskii's fixed point theorem to prove the existence of positive periodic solutions of the second-order nonlinear neutral differential equation $$ frac{d^2}{dt^2}x(t)+p(t)frac{d}{dt}x(t)+q(t)x(t) =cfrac{d}{dt}x(t-au(t))+f(t,h(x(t)),g(x ...

Periodic solution for ϕ-Laplacian neutral differential equation

Open Mathematics, 2019
This paper is devoted to the existence of a periodic solution for ϕ-Laplacian neutral differential equation as follows (ϕ(x(t)−cx(t−τ))′)′=f(t,x(t),x′(t)).$$\begin{array}{} (\phi(x(t)-cx(t-\tau))')'=f(t,x(t),x'(t)). \end{array}$$
