Precoloring extension. I. Interval graphs [PDF]

open access: yesDiscrete Mathematics, 1992
The precoloring extension problem is defined as follows: given an integer \(k\geq 2\), a graph \(G=(V,E)\) with \(| V|\geq k\), a vertex-subest \(W\subseteq V\), and a proper \(k\)-coloring of the subgraph of \(G\) induced by \(W\), can this \(k\)-coloring be extended to a proper \(k\)-coloring of the whole graph \(G\)?

Gut microbiota diversity is prognostic in metastatic hormone receptor‐positive breast cancer patients receiving chemotherapy and immunotherapy

open access: yesMolecular Oncology, EarlyView.
In this exploratory study, we investigated the relationship between the gut microbiota and outcome in patients with metastatic hormone receptor‐positive breast cancer, treated in a randomized clinical trial with chemotherapy alone or chemotherapy in combination with immune checkpoint blockade.

Modeling hepatic fibrosis in TP53 knockout iPSC‐derived human liver organoids

open access: yesMolecular Oncology, EarlyView.
This study developed iPSC‐derived human liver organoids with TP53 gene knockout to model human liver fibrosis. These organoids showed elevated myofibroblast activation, early disease markers, and advanced fibrotic hallmarks. The use of profibrotic differentiation medium further amplified the fibrotic signature seen in the organoids.

On the Representation of a PI-Graph

open access: yesTrends in Computational and Applied Mathematics, 2007
Consider two parallel lines (denoted r1 and r2). A graph is a PI graph (Point-Interval graph) if it is an intersection graph of a family F of triangles between r1 and r2 such that each triangle has an interval with two endpoints on r1 and a vertex (a ...

In vitro properties of patient serum predict clinical outcome after high dose rate brachytherapy of hepatocellular carcinoma

open access: yesMolecular 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.

Interval Graphs and Proper Interval Graphs in Fuzzy and Neutrosophic Graphs

open access: yesInformation Sciences with Applications
Interval graphs represent vertices as intervals on the real line, with edges denoting overlapping intervals, while proper interval graphs prevent one interval from being fully contained within another. This paper explores interval and proper interval graphs within the frameworks of fuzzy, neutrosophic, and Turiyam Neutrosophic graphs.

A synthetic benzoxazine dimer derivative targets c‐Myc to inhibit colorectal cancer progression

open access: yesMolecular Oncology, EarlyView.
Benzoxazine dimer derivatives bind to the bHLH‐LZ region of c‐Myc, disrupting c‐Myc/MAX complexes, which are evaluated from SAR analysis. This increases ubiquitination and reduces cellular c‐Myc. Impairing DNA repair mechanisms is shown through proteomic analysis.

On Homogeneously Representable Interval Graphs [PDF]

open access: yesNational Academy Science Letters, 2015
We determine all graphs whose line graphs (middle graphs, total graphs, respectively) are homogeneously representable interval graphs.
