Advanced Healthcare Materials, EarlyView.Most in vitro cancer models lack cellular diversity, functional complexity, and clinical relevance. This work highlights the generation of an innovative dynamic tetraculture with autologous patient‐derived cells within a vascularized tumor‐on‐chip, as well as the recapitulation of endothelial anergy features induced by the tumor microenvironment ...

Investigate Invertibility of Sparse Symmetric Matrix
, 2017 In this paper, we investigate the invertibility of sparse symmetric matrices. We show that for an $n\times n$ sparse symmetric random matrix $A$ with $A_{ij} = _{ij} _{ij}$ is invertible with high probability. Here, $ _{ij}$s, $i\ge j$ are i.i.d. Bernoulli random variables with $\mathbb{P} \left( _{ij}=1 \right) =p \ge n^{-c}$, $ _{ij}, i\ge j ...

Glucocorticoids Alter Bone Microvascular Barrier via MAPK/Connexin43 Mechanisms
Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.Osteoporosis induced by Glucocorticoids (GCs) is a common complication of long‐term GC use in patients with inflammatory and autoimmune conditions, often leading to an increased fracture risk. A 3D bicellular endo‐osteo microfluidic platform is developed to explore pathogenic mechanisms underlying GCs‐induced osteoporosis, highlighting a novel MAPK ...

INVERTIBILITY OF SUBMATRICES OF THE PASCAL MATRIX AND BIRKHOFF INTERPOLATION
Journal of Mathematical Sciences: Advances and Applications, 2016 The infinite upper triangular Pascal matrix is T = [( j )i] for 0 ≤ i, j. It is easy to see that any leading principle square submatrix is triangular with determinant 1, hence invertible. In this paper, we investigate the invertibility of arbitrary square submatrices Tr, c comprised of rows r = [r0, … , rm ] and columns c = c0 , … , cm[] of T. We

Thermoresponsive BrushGel Microcarriers for Efficient Cell Expansion and Enzyme‐Reduced Harvesting
Advanced Healthcare Materials, EarlyView.Askari et al, report on temperature‐responsive microcarriers to minimize enzyme use and cost in dynamic cultures. Abstract Scaling up cell therapy requires efficient expansion of high‐quality cells. Microcarrier(MC)‐based systems offer high surface‐to‐volume ratios and reduce culture media usage.

Advanced Healthcare Materials, EarlyView.A) SLM generates biomimetic bone scaffolds with consistent porosity but varying TPMS‐Gyroid unit cell designs (TG15, TG20, TG25, TG30). B) By enhancing the expression of ITGB1, TPMS‐Gyroid scaffolds can facilitate osteogenic differentiation in BMSCs and promote M2 polarization in macrophages.
