Range of semilinear operators for systems at resonance
Electronic Journal of Differential Equations, 2012 For a vector function $u:mathbb{R} o mathbb{R}^N $ we consider the system $$displaylines{ u''(t)+ abla G(u(t))= p(t)cr u(t)=u(t+T), }$$ where $G: mathbb{R}^N o mathbb{R}$ is a $C^1$ function.

Molecular Oncology, EarlyView.This study indicates that Merkel cell carcinoma (MCC) does not originate from Merkel cells, and identifies gene, protein & cellular expression of immune‐linked and neuroendocrine markers in primary and metastatic Merkel cell carcinoma (MCC) tumor samples, linked to Merkel cell polyomavirus (MCPyV) status, with enrichment of B‐cell and other immune cell

Heteroclinic orbits of a second order nonlinear difference equation
Electronic Journal of Differential Equations, 2017 This article concerns a second-order nonlinear difference equation. By using critical point theory, the existence of two heteroclinic orbits is obtained. The main method used is variational.

Emerging role of ARHGAP29 in melanoma cell phenotype switching
Molecular Oncology, EarlyView.This study gives first insights into the role of ARHGAP29 in malignant melanoma. ARHGAP29 was revealed to be connected to tumor cell plasticity, promoting a mesenchymal‐like, invasive phenotype and driving tumor progression. Further, it modulates cell spreading by influencing RhoA/ROCK signaling and affects SMAD2 activity. Rho GTPase‐activating protein

A modified zero energy critical point theory with applications to several nonlocal problems
Electronic Journal of Qualitative Theory of Differential EquationsIn this paper, we devote ourselves to considering a modified zero energy critical point theory for a specific set of functionals denoted as $\Phi_{\mu}$, defined within the confines of a uniformly convex Banach space.

Molecular Oncology, EarlyView.Following high dose rate brachytherapy (HDR‐BT) for hepatocellular carcinoma (HCC), patients were classified as responders and nonresponders. Post‐therapy serum induced increased BrdU incorporation and Cyclin E expression of Huh7 and HepG2 cells in nonresponders, but decreased levels in responders.

Critical point theory for symmetries with fixed points
, 2010 Gegenstand der Arbeit ist die Suche nach kritischen Punkten einer stetig differenzierbarer Funktion f auf einer Banach-Mannigfaltigkeit X, die invariant unter der Wirkung einer (kompakten Lie-) Symmetriegruppe G ist. Es gebe eine kompakte G-Mannigfaltigkeit M und eine G-äquivariante Surjektion von X auf M mit einem G-äquivarianten Schnitt, so dass sich

Molecular Oncology, EarlyView.Adaptaquin selectively kills glioma stem cells while sparing differentiated brain cells. Transcriptomic and proteomic analyses show Adaptaquin disrupts iron and cholesterol homeostasis, with iron chelation amplifying cytotoxicity via cholesterol depletion, mitochondrial dysfunction, and elevated reactive oxygen species.
