Equitable Coloring and Equitable Choosability of Planar Graphs without chordal 4- and 6-Cycles [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2019
A graph $G$ is equitably $k$-choosable if, for any given $k$-uniform list assignment $L$, $G$ is $L$-colorable and each color appears on at most $\lceil\frac{|V(G)|}{k}\rceil$ vertices.

Single‐Cell RNA Sequencing Reveals the Heterogeneity in Differentiation Trajectory and Tumor Microenvironment Leading to More Aggressive Phenotypes of Papillary Thyroid Cancer in Children and Young Adult Patients

open access: yesAdvanced Science, EarlyView.
scRNA sequencing reveals distinct tumor ecosystem features in CAYA‐PTC, marked by enriched CD4T_Tfh, CD8T_Tex cells, and rapid malignant thyrocyte differentiation (absent of mild‐state BRAF‐like population) toward invasive states. Prominent emCAF_LAMP5 populations interact with endothelial cells and thyrocytes facilitate angiogenesis and metastasis ...

Generalized chordality, vertex separators and hyperbolicity on graphs

open access: yes, 2017
Let $G$ be a graph with the usual shortest-path metric. A graph is $\delta$-hyperbolic if for every geodesic triangle $T$, any side of $T$ is contained in a $\delta$-neighborhood of the union of the other two sides.

Integrative Omics Reveals Glutamine Catabolism‐Driven Apoptotic Suppression in Monocytes upon Mechanical Unloading

open access: yesAdvanced Science, EarlyView.
This research integrated multi‐omics analysis of bone tissue from HLU and control mice revealed that mechanical unloading suppresses intrinsic apoptosis and augments glutamine (Gln) catabolism in osteoclast lineage cells. The findings highlight pivotal roles for SLC1A5‐mediated Gln metabolism and XIAP/Diablo axis‐mediated apoptosis suppression.

Complement of the generalized total graph of fields

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
Let R be a commutative ring and H be a multiplicative prime subset of R. The generalized total graph is the undirected simple graph with vertex set R and two distinct vertices x and y are adjacent if For a field F, is the only multiplicative prime subset

Aligned Conductive Magnetic Nanofibers with Directional Magnetic Field Stimulation Promotes Peripheral Nerve Regeneration

open access: yesAdvanced Science, EarlyView.
Peripheral nerve injury necessitates alternatives to autografts. This study combines magnetic nanoparticles, oriented PCL fibers, and Ppy to create a conductive, magnetically active scaffold. In vitro and in vivo experiments demonstrated enhanced downstream pathways of calcium signaling, as revealed by transcriptome analysis.

Nanocatalytic Neuroprotection and Neurological Recovery Post‐Traumatic Brain Injury

open access: yesAdvanced Science, EarlyView.
This study demonstrates that combining Ce0.7Zr0.3O2 nanozymes with nimodipine enhances neuroprotection after traumatic brain injury. The therapy reduces oxidative stress, neuronal apoptosis, and improves blood–brain barrier integrity, with nanozymes effective at low doses.

Regulating PPARG Reduces Lipid Accumulation in Microglia and Promotes Functional Recovery After Spinal Cord Injury

open access: yesAdvanced Science, EarlyView.
Macrophages infiltrate the spinal cord post‐injury, decreasing over time. Microglia phagocytose myelin debris, increasing lipid accumulation. Macrophage deletion improves outcomes, while microglial deletion worsens them. The LD+ microglia subtype shows abnormal Pparg signaling.
