Natural Products as Geroprotective Modulators in Diabetic Nephropathy: A Mechanistic Framework Integrating Aging Hallmarks and the AMPK–SIRT1–Nrf2 Axis

Aging and Cancer, EarlyView.
Natural products target the aging kidney in diabetic nephropathy by restoring the AMPK–SIRT1–Nrf2 axis, reducing oxidative stress, inflammation, fibrosis, and cellular senescence while enhancing mitochondrial biogenesis and antioxidant defenses.

Diffusion-induced spontaneous pattern formation on gelation surfaces

, 2006
Although the pattern formation on polymer gels has been considered as a result of the mechanical instability due to the volume phase transition, we found a macroscopic surface pattern formation not caused by the mechanical instability.

Instability of a plane conducting free surface submitted to an alternating magnetic field [PDF]

, 1998
This paper considers the stability of a horizontal liquid-metal free surface in the presence of a horizontal alternating magnetic field. A weak formulation is used to derive a generalized Mathieu–Hill equation for the evolution of surface perturbations ...

On Taylor Instability of Plane Surfaces [PDF]

The Physics of Fluids, 1959
A number of special results on combined Taylor and Helmholtz instability are readily derivable by imposing a constant velocity parallel to, and acceleration normal to, the interface such that the interfacial wave appears to be stationary.

Life‐Threatening Bradycardia in Anti‐NMDA‐Receptor Encephalitis and a Novel Use for Permanent Pacing

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Pediatric anti‐NMDA receptor encephalitis (pNMDARE) is an autoantibody‐mediated disorder that can cause severe autonomic dysfunction, including symptomatic bradycardia and asystole. Dysautonomia can last for years, making it very challenging to manage.

Experimental study on the mechanical properties and crack evolution patterns of sandstone with prefabricated double fractures in sub-instability stage

矿业科学学报
As coal mining in China gradually shifts from shallow to deep layers, the impact of mining disturbances increases, making it more difficult to control the development of surrounding rock fractures. This study aims to investigate the effect of rock bridge

Charged-Surface Instability Development in Liquid Helium; Exact Solutions [PDF]

, 2000
The nonlinear dynamics of charged-surface instability development was investigated for liquid helium far above the critical point. It is found that, if the surface charge completely screens the field above the surface, the equations of three-dimensional (

Super‐Refractory Status Epilepticus (SRSE) in a Patient With Compound Heterozygous OPA1 Variants: Case Report and Literature Review

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Super‐Refractory Status Epilepticus (SRSE) is a rare, life‐threatening neurological emergency with unclear etiology in many cases. Mitochondrial dysfunction, often due to disease‐causing genetic variants, is increasingly recognized as a cause, with each gene producing distinct pathophysiological mechanisms.

The influence of electron cyclotron resonance heating on ion-driven fishbone instability

Nuclear Fusion, 2023
The effect of electron cyclotron resonance heating (ECRH) on fishbone instability is studied based on the generalized energy principle. Off-axis ECRH plays a stabilizing role in fishbone instability, while on-axis ECRH does not distinctly change the ...
