Degree Sequences of Monocore Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2014
A k-monocore graph is a graph which has its minimum degree and degeneracy both equal to k. Integer sequences that can be the degree sequence of some k-monocore graph are characterized as follows. A nonincreasing sequence of integers d0, . . . , dn is the

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

The therapeutic opportunities and pitfalls of using iron ion chelators to treat neurodegenerative diseases

open access: yesFEBS Letters, EarlyView.
Although too much iron in the brain promotes neurodegeneration, iron ion chelators have had mixed effects in clinical trials. This review explains why; some chelators do not render the iron redox‐inactive (e.g., L1) whereas others do (e.g., desferrioxamine).

A short proof of Brooks’ Theorem for vertex arboricity

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
The vertex-arboricity of a graph is the minimum number of subsets that the vertices of can be partitioned so that the subgraph induced by each set of vertices is a forest. Kronk and Mitchem proved a generalization of Brooks’ Theorem for vertex arboricity,

Degeneracy and stability in neural circuits of dopamine and serotonin neuromodulators: A theoretical consideration

open access: yesFrontiers in Computational Neuroscience, 2023
Degenerate neural circuits perform the same function despite being structurally different. However, it is unclear whether neural circuits with interacting neuromodulator sources can themselves degenerate while maintaining the same neuromodulatory ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Degeneracy and Complexity in Neuro-Behavioral Correlates of Team Coordination

open access: yesFrontiers in Human Neuroscience, 2020
Team coordination—members of a group acting together rather than performing specific actions individually—is essential for success in many real-world tasks such as military missions, sports, workplace, or school interactions.

Liquid biopsy‐based diagnostic evaluation of hypermethylated CpG sites for ovarian cancer diagnosis

open access: yesMolecular Oncology, EarlyView.
This schematic outlines the workflow from biomarker identification to duplex MethyLight assay validation for epithelial ovarian cancer diagnosis using cfDNA‐based liquid biopsy. Initial screening of hypermethylated CpG candidates (cg02957270, cg10061138 cg00480298, COL2A1) was performed in tissue using ARMS‐PCR, COBRA, qPCR and image analysis. Selected

Reaction diffusion equations with boundary degeneracy

open access: yesElectronic Journal of Differential Equations, 2016
In this article, we consider the reaction diffusion equation $$ \frac{\partial u}{\partial t} = \Delta A(u),\quad (x,t)\in \Omega \times (0,T), $$ with the homogeneous boundary condition.

“Nature Made Us This Way…”: Crime without Punishment? (Fyodor Dostoevsky and Ivan Bunin). Article 2: “Are There Such Signs at Birth?” [PDF]

open access: yesДостоевский и мировая культура: Филологический журнал
The article examines the thesis of marginal anthropology as represented by Fyodor Dostoevsky in the novel Crime and Punishment and creatively reinterpreted by Ivan Bunin in the short story “Loopy Ears,” under the influence of the achievements of the ...
