Neighborhood Signed Graphs

, 2012
A \emph{signed graph (marked graph)} is an ordered pair $S = (G, \sigma)$ ($S =(G, \mu)$), where $G=(V,E)$ is a graph called the \emph{underlying graph} of $S$ and $\sigma : E \rightarrow \{+,-\}$ ($\mu : V \rightarrow \{+,-\}$) is a function.

Clinical manifestations of dual‐gene variants in retinitis pigmentosa

Acta Ophthalmologica, EarlyView.
Abstract Purpose Retinitis pigmentosa (RP) is an inherited retinal disease (IRD), whereby each affected individual typically harbours pathogenic variants in a single causative gene, yet the disorder exhibits marked genetic heterogeneity, with more than 100 genes reported to underlie RP.

Bounds on the signed domination number of a graph.

, 2001
Let G = (V, E) be a simple graph on vertex set V and define a function f: V →{−1, 1}. The function f is a signed dominating function if for every vertex x ∈ V, the closed neighborhood of x contains more vertices with function value 1 than with −1.

Ecological variability of Hippopotamus antiquus from the late Early–Middle Pleistocene of Megalopolis Basin (Greece): Evidence for dynamic habitats in a glacial microrefugium

Boreas, EarlyView.
This study investigates the ecology of the extinct European Hippopotamus from the late Early–Middle Pleistocene (c. 900–400 ka) sequence of the Megalopolis Basin, a glacial microrefugium for temperate taxa in southern Greece. Using stable carbon (δ13C) and oxygen (δ18O) isotope analyses and microwear analyses of Hippopotamus dental elements, we ...

Brain metastasis‐associated fibroblasts shape the tumour microenvironment to enhance cancer cell invasion

Brain Pathology, EarlyView.
Brain metastasis‐associated fibroblasts are active stromal components of the metastatic niche characterised by extracellular matrix remodelling and production of pro‐migratory mediators. They promote monocyte and cancer cell migration and enhance cancer cell invasion while having no growth‐promoting effect on cancer cells.

NMDA receptor subunit‐dependent analysis of radiprodil inhibition in neonatal male rat substantia nigra dopaminergic neurons

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Radiprodil is a GluN2B subunit selective NMDA receptor negative allosteric modulator which is currently under clinical investigation as a possible anti‐epileptic drug for paediatric use. Our goal was to investigate the inhibition of dopaminergic neuron NMDA responses by radiprodil.
