Engineering Extracellular Vesicle Production Through Magnetic Ion Channel Activation for Bone Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
Magnetic Ion Channel Activation (MICA) enables remote stimulation of mechanosensitive ion channels using functionalised magnetic nanoparticles, enhancing extracellular vesicle (EV) biogenesis is pre‐osteoblasts. MICA desrived EVs exhibit typical nano‐vesicular characteristics but display superior pro‐osteogeneic activity, promoting mesenchymal stem ...

Regularity for compressible isentropic Navier-Stokes equations with cylinder symmetry

open access: yesJournal of Inequalities and Applications, 2016
This paper is concerned with the regularity of the global solutions in H 4 $H^{4}$ to the compressible isentropic Navier-Stokes equations with the cylinder symmetry in R 3 $R^{3}$ . Such a circular coaxial cylinder symmetric domain is an unbounded domain,

Attractors for reaction-diffusion equations on arbitrary unbounded domains

open access: yes, 2007
We prove existence of global attractors for parabolic equations of the form $$u_t+\beta(x)u-\sum_{ij}\partial_i(a_{ij}(x)\partial_j u)=f(x,u)$$ with Dirichlet boundary condition on an arbitrary unbounded domain $\Omega$ in $\R^3$, without smoothness ...

Aptamer‐Based Delivery Systems for VEGF and NGF Modulation in Ocular Therapies

open access: yesAdvanced Healthcare Materials, EarlyView.
Aptamer‐based delivery systems targeting NGF and VEGF hold significant potential for precise and sustained treatment of complex diseases affecting both the anterior and posterior segments of the eye. This review critically summarizes current strategies for NGF and VEGF delivery as well as VEGF sequestration, providing a clinical perspective on how ...

Semilinear elliptic problems in unbounded domains with unbounded boundary

open access: yesAsymptotic Analysis, 2004
This paper deals with a class of singularly perturbed nonlinear elliptic problems (Pε) with subcritical nonlinearity. The coefficient of the linear part is assumed to concentrate in a point of the domain, as ε→0, and the domain is supposed to be unbounded and with unbounded boundary.

Soft Neural Interfaces for Circuit‐Level Analysis of Magnetogenetic Deep Brain Stimulation in Parkinson's Disease Models

open access: yesAdvanced Healthcare Materials, EarlyView.
ABSTRACT Magnetogenetic deep brain stimulation (MG‐DBS) represents a wireless neuromodulation that has demonstrated long‐lasting behavioral benefits in Parkinson's disease models. However, the circuit‐level mechanisms underlying these therapeutic effects have remained uncharacterized due to limitations of conventional neural interfaces.

On Unbounded Positive *-Representationson Fréchet-Domains

open access: yesPublications of the Research Institute for Mathematical Sciences, 1994
Let D be a Fréchet-domain from Op*-algebra, abbreviated F-domain. The present paper is concerned with the study of positive *-representations of L +( D ), of the Calkin representation of L

A Physiological Microfluidic Blood–Brain‐Barrier Model for In Vitro Study of Nanoparticle Trafficking and Accumulation

open access: yesAdvanced Healthcare Materials, EarlyView.
A human microfluidic blood‐brain barrier (mBBB) model enables spatially resolved comparison of nanoparticle trafficking. Extracellular vesicles (EVs), liposomes, and nanoplastics exhibit distinct transport and disruption behaviors, revealing that membrane composition and uptake pathways govern BBB interaction.

A high-order finite difference scheme incorporating analytical absorbing boundary conditions for variable-order time-fractional diffusion equations on unbounded domains

open access: yesPartial Differential Equations in Applied Mathematics
We propose a new numerical method to solve nonlinear parabolic diffusion problems with a time dependent Caputo fractional derivative in an unbounded spatial domain.

Dynamical behaviors of stochastic local Swift-Hohenberg equation on unbounded domain

open access: yesJournal of Inequalities and Applications, 2016
In this paper, we first study the deterministic Swift-Hohenberg equation on a bounded domain. After obtaining some a priori estimates by the uniform Gronwall inequality, we prove the existence of an attractor by the Sobolev compact embeddings.
