A Deployable 4D Printed, Mucoadhesive and Magnetically Guided Patch for Local Therapy of Gastric Cancer

open access: yesAdvanced Healthcare Materials, EarlyView.
A new perspective for treatment of gastric cancer is proposed utilizing 4D printing to develop shape morphing, deployable, and magnetically guided local drug releasing patches. The deployed patches are envisioned to adhere at the tumor site to locally deliver high drug amounts.

Critical Neumann problem for nonlinear elliptic systems in exterior domains

open access: yesElectronic Journal of Differential Equations, 2008
In this paper, we investigate the Neumann problem for a critical elliptic system in exterior domains. Assuming that the coefficient $Q(x)$ is a positive smooth function and $lambda$, $mugeq0$ are parameters, we examine the common effect of the mean ...

Tapered Pillar Design for High‐Precision Force Readout in Miniaturized Engineered Heart Tissues From Human Pluripotent Stem Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
Engineered heart tissues (EHTs) are a valuable approach in capturing human cardiac physiology and drug responses in vitro. Here, a novel tapered pillar design is developed in an EHT platform to confine tissues in a predefined position‐ at the middle of the pillar height.

Inhalability and Bioactivity of Spray‐Dried versus Pressurized Gas eXpanded Liquid Technology‐Processed Yeast Beta‐Glucan Microparticles for Anti‐Fibrotic Therapies

open access: yesAdvanced Healthcare Materials, EarlyView.
PGXTEC) liquid technology is utilized to develop highly respirable yeast beta‐glucan (YBG) microparticles for the treatment of pulmonary fibrosis. Compared to conventionally processed spray‐dried YBG, PGXTEC‐YBG exhibits greatly improved aerodynamic properties, enhanced pro‐fibrotic macrophage uptake, and effective downregulation of pro‐fibrotic ...

Controlling Intestinal Organoid Polarity using Synthetic Dynamic Hydrogels Decorated with Laminin‐Derived IKVAV Peptides

open access: yesAdvanced Healthcare Materials, EarlyView.
Design rules are presented to control intestinal organoid polarity in fully synthetic hydrogels. The laminin‐derived IKVAV sequence is crucial to obtain correct intestinal organoid polarity. Increasing hydrogel dynamics further supports the growth of correctly polarized intestinal organoids, while a bulk level of stiffness (G’ ≈ 0.7 kPa) is crucial to ...

Existence results for Hamiltonian elliptic systems with nonlinear boundary conditions

open access: yesElectronic Journal of Differential Equations, 1999
We prove the existence of nontrivial solutions to the system $$ Delta u = u, quad Delta v = v, $$ on a bounded set of $R^N$, with nonlinear coupling at the boundary given by $$partial u/partialeta = H_v,quad partial v/partialeta = H_u,.$$ The proof is ...
