Large‐scale bidirectional arrayed genetic screens identify OXR1 and EMC4 as modifiers of αSynuclein aggregation

FEBS Open Bio, EarlyView.
Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

Hyperbolic-parabolic singular perturbation for mildly degenerate Kirchhoff equations: Decay-error estimates

, 2012
We consider degenerate Kirchhoff equations with a small parameter in front of the second-order time-derivative. It is well known that these equations admit global soluions when the parameter is small enough, and that these solutions decay with the same ...

Comprehensive Assessment of Arterial, Tissue, and Venous Collaterals for Evaluating the Infarct Growth Rate: The Multimodal Collateral Score

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Collaterals are crucial factors that influence the infarct growth rate (IGR). We aimed to determine whether a comprehensive multimodal collateral score (MCS), incorporating collateral assessment at the arterial, tissue, and venous levels, is associated with functional independence and provides incremental prognostic value over ...

On a Mixed Problem for a Third Order Degenerating Hyperbolic Equation

Вестник КРАУНЦ. Физико-математические науки, 2023
В работе исследуется смешанная краевая задача для гиперболического уравнения третьего порядка с вырождением порядка внутри области. В положительной части области рассматриваемое уравнение совпадает с уравнением Аллера, которое является уравнением третьего порядка гиперболического типа, хотя его принято называть уравнением псевдопараболического типа.

Well-posedness For Non-Isotropic Degenerate Parabolic-Hyperbolic Equations

, 2002
We develop a well-posedness theory for solutions in L1 to the Cauchy problem of general degenerate parabolic-hyperbolic equations with non-isotropic nonlinearity.

Adaptive Observer for Coupled Wave PDE and Infinite ODE With Sampled Data and Unknown Input: Application to Brain Hemodynamics Estimation

International Journal of Adaptive Control and Signal Processing, EarlyView.
This article proposes a convergent adaptive observer for a damped wave PDE and an infinite‐dimensional ODE coupled in cascade using sampled‐in‐space ODE state measurements. The proposed observer estimates the distributed states of the PDE and ODE along with unknown PDE parameters and spatial input.
