Eccentricity-Based Topological Indices of a Cyclic Octahedron Structure

Mathematics, 2018
In this article, we study the chemical graph of a cyclic octahedron structure of dimension n and compute the eccentric connectivity polynomial, the eccentric connectivity index, the total eccentricity, the average eccentricity, the first Zagreb index ...

RIPK4 function interferes with melanoma cell adhesion and metastasis

Molecular Oncology, EarlyView.
RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.

Diabetes‐induced vascular calcification is associated with low pyrophosphate and its oral supplementation prevents calcification in diabetic mice

FEBS Open Bio, EarlyView.
Induction of diabetes in three different mouse strains uniformly resulted in an increase in TNAP activity and a reduction in pyrophosphate (PPi) in the circulation. Inhibition of TNAP restored plasma PPi. Diabetes‐induced calcification in the media layer of the aorta was detected only in the Abcc6−/− strain, which is predisposed to ectopic ...

Leap Eccentric Connectivity Index of Subdivision Graphs

Journal of Mathematics, 2022
The second degree of a vertex in a simple graph is defined as the number of its second neighbors. The leap eccentric connectivity index of a graph M, LξcM, is the sum of the product of the second degree and the eccentricity of every vertex in M.

Distance eccentric connectivity index of graphs

, 2021
Summary: Let \(G = ( V, E )\) be a connected graph. The eccentric connectivity index of \(G\) is defined by \(\xi^C ( G ) = \sum_{u \in V (G)} \deg(u) e (u)\), where \(\deg(u)\) and \(e ( u )\) denote the degree and eccentricity of the vertex \(u\) in \(G\), respectively.
