Molecular Oncology, EarlyView.Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

On some non-periodic branch groups
, 2013 This thesis studies some classes of non-periodic branch groups. In particular their growth, relations between elements and their Hausdorff dimensions.This thesis is not currently available in ...

Molecular Oncology, EarlyView.Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.

A characterization of maximally almost periodic groups
, 1979 It is proved that a topological group G is maximally almost periodic if and only if G admits an action π \pi on a compact Hausdorff space X such that the transformation group ( X , G , π

Cyclicity in families of circle maps [PDF]
, 2013 In this paper we will study families of circle maps of the form x↦x+2πr+af(x)(mod2π) and investigate how many periodic trajectories maps from this family can have for a ‘typical’ function f provided the parameter a is ...

Somatic mutational landscape in von Hippel–Lindau familial hemangioblastoma
Molecular Oncology, EarlyView.The causes of central nervous system (CNS) hemangioblastoma in Von Hippel–Lindau (vHL) disease are unclear. We used Whole Exome Sequencing (WES) on familial hemangioblastoma to investigate events that underlie tumor development. Our findings suggest that VHL loss creates a permissive environment for tumor formation, while additional alterations ...

Molecular Oncology, EarlyView.Targeted therapy was evaluated in SHH medulloblastoma using neuroepithelial stem cell (NES) and tumor‐derived NES‐like (tNES) models in 2D monolayers and 3D spheroids. PI3K, AKT, and CDK4/6 inhibitors had minimal effects in NES but markedly reduced viability and growth and induced apoptosis in tNES cells, revealing distinct therapeutic vulnerabilities.

The Lattice of Periods of a Group Action
Advances in Mathematics, 1995 Let \(G\) be a finite group and \(S\) a finite set. An action of \(G\) on \(S\) yields a partition of \(S\) given by the orbits of the action. By restricting the action to subgroups, one obtains an order-preserving map from the lattice of subgroups of \(G\) to the lattice of partitions of \(S\). The image of this map is called the lattice of periods of
