Gut microbiota alterations in patients with non‐small‐cell lung cancer undergoing chemoradiotherapy

open access: yesMolecular Oncology, EarlyView.
We investigated the impact of concurrent chemoradiotherapy (CRT) on the gut microbiota in patients with locally advanced non‐small‐cell lung cancer. Overall gut microbiota composition remained largely stable throughout CRT while antibiotic exposure may influence microbial diversity.

EXISTENTIALLY CLOSED PROPERTY IN DIRECTED INFINITE GRAPHS [PDF]

open access: yes, 2018
Graph theory abounds with applications inside mathematics itself, and in computer science, and engineering. One direction of research within graph theory is the topic of infinite graphs, which is the focus of this thesis.

Colour number, capacity and perfectness of directed graphs.

open access: yes, 2000
We introduce a new concept of chromatic number for directed graphs, called the colour number and use it to upper bound the transitive clique number and the Sperner capacity of arbitrary directed graphs.

Predictive and prognostic biomarkers of Bacillus Calmette‐Guérin therapy failure in bladder cancer patients: A systematic review

open access: yesMolecular Oncology, EarlyView.
High‐risk bladder cancer is typically treated with Bacillus Calmette‐Guérin (BCG), but 30–40% of patients relapse. No FDA‐ or CE‐approved biomarkers currently predict or prognosticate BCG failure. We systematically reviewed the literature and identified 72 eligible studies, revealing several promising biomarkers associated with BCG treatment response ...

Semi-Local Integration Measure for Directed Graphs

open access: yesMathematics
Directed and weighted graphs can be used for many real-world applications to model and analyse the quality and structure of communication within the system, the distribution and flow of information, and various resources, dependencies, resilience, etc ...

Twin minus domination numbers in directed graphs

open access: yesCommunications in Combinatorics and Optimization, 2016
Let $D=(V,A)$ be a finite simple directed graph‎. ‎A‎ ‎function $f:V\longrightarrow \{-1,0,1\}$ is called a twin minus‎ ‎dominating function if $f(N^-[v])\ge 1$ and $f(N^+[v])\ge‎ ‎1$ for each vertex $v\in V$‎. ‎The twin minus domination number of‎ ‎

Directed acyclic graphs: A tool to identify confounders in orthodontic research, Part II [PDF]

open access: yes, 2017
In the previous article, we discussed the problem of confounding and presented 3 fundamental methods for assessing and adjusting for confounders: the traditional approach, the noncollapsibility approach, and the directed acyclic graphs (DAGs) or causal ...
