PERIODIC SOLUTIONS AND SLOW MANIFOLDS [PDF]

open access: yesInternational 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

open access: yesMolecular 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.

Methylation biomarkers can distinguish pleural mesothelioma from healthy pleura and other pleural pathologies

open access: yesMolecular Oncology, EarlyView.
We developed and validated a DNA methylation–based biomarker panel to distinguish pleural mesothelioma from other pleural conditions. Using the IMPRESS technology, we translated this panel into a clinically applicable assay. The resulting two classifier models demonstrated excellent performance, achieving high AUC values and strong diagnostic accuracy.

Periodic solutions of spatially periodic hamiltonian systems

open access: yesJournal of Differential Equations, 1992
The existence of periodic solutions for Hamiltonian systems of ordinary differential equations (1) \(\dot z=J(H_ z(z,t)+f(t))\) is studied, where \(H: R^{2n}\times R\to R\) is of class \(C^ 1\) and is \(2\pi\)-periodic with respect to \(t\); \(f: R\to R\) is continuous and \(2\pi\)-periodic and \(J=\bigl({0 \atop I_ n} {-I_ n \atop 0}\bigr)\).

Next‐generation proteomics improves lung cancer risk prediction

open access: yesMolecular Oncology, EarlyView.
This is one of very few studies that used prediagnostic blood samples from participants of two large population‐based cohorts. We identified, evaluated, and validated an innovative protein marker model that outperformed an established risk prediction model and criteria employed by low‐dose computed tomography in lung cancer screening trials.

A Novel Approach to a Time-Dependent-Coefficient WBK System: Doubly Periodic Waves and Singular Nonlinear Dynamics

open access: yesComplexity, 2018
Under investigation in this paper is a more general time-dependent-coefficient Whitham-Broer-Kaup (tdcWBK) system, which includes some important models as special cases, such as the approximate equations for long water waves, the WBK equations in shallow

Exploiting metabolic adaptations to overcome dabrafenib treatment resistance in melanoma cells

open access: yesMolecular Oncology, EarlyView.
We show that dabrafenib‐resistant melanoma cells undergo mitochondrial remodeling, leading to elevated respiration and ROS production balanced by stronger antioxidant defenses. This altered redox state promotes survival despite mitochondrial damage but renders resistant cells highly vulnerable to ROS‐inducing compounds such as PEITC, highlighting redox

Variational Methods for Almost Periodic Solutions of a Class of Neutral Delay Equations

open access: yesAbstract and Applied Analysis, 2008
We provide new variational settings to study the a.p. (almost periodic) solutions of a class of nonlinear neutral delay equations. We extend Shu and Xu (2006) variational setting for periodic solutions of nonlinear neutral delay equation to the ...
