Aggregate, EarlyView.The selenium‐containing polyurethane (SePU) thermo‐sensitive hydrogel (SePU/HBC) was constructed by incorporating SePU into hydroxybutyl chitosan (HBC). This hydrogel alleviates endoplasmic reticulum stress (ERS) and inhibits cell apoptosis by activating the unfolded protein response (UPR), thereby promoting diabetic wound healing.

Synergistic effect of phosphodiesterase 4 inhibitor and serum on migration of endotoxin-stimulated macrophages. [PDF]
, 2018 Macrophage migration is an essential step in host defense against infection and wound healing. Elevation of cAMP by inhibiting phosphodiesterase 4 (PDE4), enzymes that specifically degrade cAMP, is known to suppress various inflammatory responses in ...

Biomimetic Chemotactic Motion of Self‐Assembling Doublet Microrobots
Advanced Intelligent Systems, EarlyView.This article studies the shape‐dependent chemotaxis of different morphologies including self‐assembled doublet microswimmers that exhibit autonomous movement in hydrogen peroxide H2O2 gradients. Without the need for complex material preparation a novel type of chemotactic active matter is produced, which allows the separation of propulsion and cargo ...

Cell-to-cell variation sets a tissue-rheology-dependent bound on collective gradient sensing
, 2017 When a single cell senses a chemical gradient and chemotaxes, stochastic receptor-ligand binding can be a fundamental limit to the cell's accuracy. For clusters of cells responding to gradients, however, there is a critical difference: even genetically ...

Feeding ducks, bacterial chemotaxis, and the Gini index
, 2015 Classic experiments on the distribution of ducks around separated food sources found consistency with the `ideal free' distribution in which the local population is proportional to the local supply rate.

Animal Models and Experimental Medicine, EarlyView.Neutrophil‐to‐lymphocyte ratio (NLR) and monocyte‐to‐lymphocyte ratio (MLR) were investigated as potential markers. A total of 3545 subjects were included in the analysis retrospectively. Adult men and women with impaired glucose metabolism were assessed. NLR and MLR may help assess inflammation in individuals with impaired glucose metabolism. Abstract

Comparison of the pathogenicity of multiple SARS‐CoV‐2 variants in mouse models
Animal Models and Experimental Medicine, EarlyView.We assessed the pathogenicity of various SARS‐CoV‐2 variants using two distinct mouse models. Our findings indicated that earlier variants, including WH‐09, Beta, and Delta, exhibited greater pathogenicity than later variants. Specifically, the Omicron variant demonstrated reduced pathogenicity, characterized by a shorter disease course and diminished ...
