T-periodic solutions and a priori bounds
Mathematical and Computer Modelling, 2000 In view of Schaefer's theorem, in the case of a normed linear space \((B,\parallel \cdot \parallel)\) and of a continuous mapping \(H\) of \(B\) into \(B\) which is compact on each bounded subset of \(B\), we have either (i) the equation \(x=\lambda Hx\) has a solution for \(\lambda =1\) or (ii) the set of all such solutions, for ...

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.

ITGAV and SMAD4 influence the progression and clinical outcome of pancreatic ductal adenocarcinoma
Molecular Oncology, EarlyView.In SMAD4‐positive pancreatic ductal adenocarcinoma (PDAC), integrin subunit alpha V (ITGAV) activates latent TGF‐β, which binds to the TGF‐β receptor and phosphorylates SMAD2/3. The activated SMAD2/3 forms a complex with SMAD4, and together they translocate to the nucleus, modulating gene expression to promote proliferation, migration, and invasion. In

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)).$$\begin{array}{} (\phi(x(t)-cx(t-\tau))')'=f(t,x(t),x'(t)). \end{array}$$

Molecular Oncology, EarlyView.This study presents a novel AI‐based diagnostic approach—comprehensive serum glycopeptide spectra analysis (CSGSA)—that integrates tumor markers and enriched glycopeptides from serum. Using a neural network model, this method accurately distinguishes liver and pancreatic cancers from healthy individuals.

Periodic solutions to Hamiltonian inclusions
Journal of Differential Equations, 1981 AbstractWe prove the existence of periodic trajectories of Hamiltonian inclusions, which reduce to the usual Hamiltonian equations in the presence of smoothness. This is accomplished via a direct variational principle involving a new action integral in an extended sense.

Exploring the role of cyclin D1 in the pathogenesis of multiple myeloma beyond cell cycle regulation
Molecular Oncology, EarlyView.Cyclin D1 overexpression altered the cell adhesion pathway, while cyclin D2 upregulation had less impact on pathway enrichment analysis. Multiple myeloma (MM) patients with cyclin D1 overexpression showed reduced CD56 expression and increased circulating tumor cells (CTC) levels, suggesting that cyclin D1 may contribute to MM cell dissemination ...
