Organoids in pediatric cancer research
FEBS Letters, EarlyView.Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Functional conservation of sequence determinants at rapidly evolving regulatory regions across mammals. [PDF]
PLoS Computational Biology, 2018 Recent advances in epigenomics have made it possible to map genome-wide regulatory regions using empirical methods. Subsequent comparative epigenomic studies have revealed that regulatory regions diverge rapidly between genome of different species, and ...

Largest Laplacian Eigenvalue and Degree Sequences of Trees [PDF]
, 2008 We investigate the structure of trees that have greatest maximum eigenvalue among all trees with a given degree sequence. We show that in such an extremal tree the degree sequence is non-increasing with respect to an ordering of the vertices that is ...

Minimum-Loop Realization of Degree Sequences
Journal of Research of the National Bureau of Standards, 1982 Given a finite sequence D of nonnegative integers, let M(D) denote its maximum element and S(D) its sum. It is known that D is realizable as a degree sequence by some graph if and only if S(D) is even, and by a loopless graph if and only if the even integer S(D) - 2M(D) ⩾ 0.

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

New Bounds For Degree Sequence Of Graphs [PDF]
Computer Science Journal of Moldova, 2019 Let $G = (V, E)$ be a simple graph with $n$ vertices, $m$ edges, and vertex degrees $d_1, d_2, ..., d_n$. Let $d_1, d_n$ be the maximum and and minimum degree of vertices. In this paper, we present lower and upper bounds for $\sum_{i=1}^{n}d_i^{2}$ and

A permutation method for network assembly.
PLoS ONE, 2020 We present a method for assembling directed networks given a prescribed bi-degree (in- and out-degree) sequence. This method utilises permutations of initial adjacency matrix assemblies that conform to the prescribed in-degree sequence, yet violate the ...

Reduced criteria for degree sequences
Discrete Mathematics, 2013 For many types of graphs, criteria have been discovered that give necessary and sufficient conditions for an integer sequence to be the degree sequence of such a graph. These criteria tend to take the form of a set of inequalities, and in the case of the Erd s-Gallai criterion (for simple undirected graphs) and the Gale-Ryser criterion (for bipartite ...

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes
FEBS Letters, EarlyView.The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only
