Diabetic Peripheral Neuropathy: Molecular Staging, Risk Factors, Therapeutics, and Emerging Trends

Med Research, EarlyView.
The heterogeneous landscape of DPN can be unified through a tripartite pathogenic model encompassing progressive stages of metabolic dysregulation, chronic inflammation, and overt neuronal damage. Within this framework, six clinical subtypes were identified, namely, hyperglycemia‐driven, dyslipidemia‐driven, inflammation‐driven, dysvascularity‐driven ...

Numerical Modeling of Hydrogen‐Assisted Cracking With Phase Field Regularized Cohesive Zone Model and Penalty‐Based Moving Hydrogen Boundary Condition

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 5, Page 1824-1844, May 2026.
ABSTRACT The degradation of metallic materials due to hydrogen embrittlement (HE) poses critical challenges for structural reliability. Phase‐field models offer an energy‐based approach that does not require predefined crack paths and automatically determines crack initiation, growth, and coalescence.
