Attenuation of arsenic trioxide‐induced endothelial injury: unveiling the protective role of ginkgolic acid through inhibition of TRPM4 SUMOylation: Evidence from Raman cellular imaging

VIEW, Volume 7, Issue 1, February 2026.
Inhibiting the SUMOylation modification of TRPM4 can prevent the vascular endothelial damage caused by ATO. Inhibition of TRPM4 SUMOylation, either pharmacologically by GA or genetically by the K618R mutation, protects against ATO‐induced vascular endothelial damage.

Automatic Adaptive and Targeted Localized Refinement in Transient Structural Dynamic Simulations Using the Multiresolution Finite Wavelet Domain Method

International Journal for Numerical Methods in Engineering, Volume 127, Issue 1, 15 January 2026.
ABSTRACT The multiresolution finite wavelet domain method has been meticulously studied in numerous wave propagation simulations, showing excellent convergence properties and very fast computing times. The multiresolution procedure always starts with the coarse solution, and then finer solutions can be superimposed on the coarse solution until ...

Exploring the Fecal Microbiome Dysbiosis and Its Plasma Metabolome Determinants in Advanced Parkinson's Disease With Motor Complications

CNS Neuroscience &Therapeutics, Volume 32, Issue 1, January 2026.
Our multiomics analysis across three PD cohorts revealed distinct fecal microbiome and plasma metabolome alterations in patients with motor complications (PD‐MC). We identified specific microbial and metabolic biomarkers and uncovered significant correlations between them, providing new insights into PD‐MC pathophysiology. ABSTRACT Background Parkinson'

Singularly perturbed stochastic systems [PDF]

Ukrainian Mathematical Journal, 1997
Summary: Problems of the singular perturbation of reducible invertible operators are classified and their applications to the analysis of stochastic Markov systems represented by random evolutions are considered. The phase merging, averaging, and diffusion approximation schemes are discussed for dynamical systems with rapid Markov switchings.

Singular Perturbation of Nonlinear Systems with Regular Singularity

Discrete Dynamics in Nature and Society, 2018
We extend Balser-Kostov method of studying summability properties of a singularly perturbed inhomogeneous linear system with regular singularity at origin to nonlinear systems of the form εzf′=Fε,z,f with F a Cν-valued function, holomorphic in a polydisc

On transformation to the singularly perturbed system

Journal of Physics: Conference Series, 2011
A rapid progress in hard- and software development of computational facilities as well as in numerical methods has increased the role of numerical simulations in the quantitative system analysis of many engineering problems. At the same time, the system complexity (in terms of dimensionality and non-linearity) has grown considerably increasing demand ...
