Global attractivity for nonlinear difference equations with delay [PDF]
In this paper, the global attractivity of the zero solution of the nonlinear delay defference equation(1.1)x(n+1)−x(n)=F(n,x(g(n))),n=0,1,2,…, is studied and the relaxed 32-conditions are obtained.

On Global Attractivity of a Class of Nonautonomous Difference Equations [PDF]
We mainly investigate the global behavior to the family of higher‐order nonautonomous recursive equations given by yn = (p + ryn−s)/(q + ϕn(yn−1, yn−2, …, yn−m) + yn−s), n ∈ ℕ0, with p ≥ 0, r, q > 0, s, m ∈ ℕ and positive initial values, and present some sufficient conditions for the parameters and maps ϕn : (ℝ+) m → ℝ+, n ∈ ℕ0, under which every ...

An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Dynamic of a nonautonomous two-species impulsive competitive system with infinite delays
In this paper, we consider a nonautonomous two-species impulsive competitive system with infinite delays. By the impulsive comparison theorem and some mathematical analysis, we investigate the permanence, extinction and global attractivity of the system,

CCDC80 suppresses high‐grade serous ovarian cancer migration via negative regulation of B7‐H3
PAX8 is a lineage‐specific master regulator of transcription in high‐grade serous ovarian cancer (HGSC) progression. We show for the first time that PAX8 facilitates proliferation and metastasis by repressing the cell autonomous tumor suppressor CCDC80 and inducing B7‐H3 expression.

LUNAR is a liver‐specific long noncoding RNA (lncRNA) that is highly expressed in normal liver but becomes epigenetically silenced in hepatocellular carcinoma through promoter hypermethylation. Loss of LUNAR is associated with NOTCH activation, epithelial–mesenchymal transition, and metastasis, whereas restoring LUNAR restrains metastatic progression ...
