Extracellular matrices for gastrointestinal surgery:Ex vivotesting and current applications

EXTRACELLULAR VESICLES AND THEIR THERAPEUTIC APPLICATIONS: A REVIEW

Background & Aims: Extracellular vesicles are double phospholipid layer vesicles releasing from several cells.  These particles contain bio-molecules including mRNA, miRNA, DNA, proteins, and lipids which play a pivotal role in the cell to cell communication. Once delivered, they participate to change target cell function, fate, morphology, differentiation, and growth. The present study is a re...

Extracellular Matrix Bioscaffolds for Building Gastrointestinal Tissue

Regenerative medicine is a rapidly advancing field that uses principles of tissue engineering, developmental biology, stem cell biology, immunology, and bioengineering to reconstruct diseased or damaged tissues. Biologic scaffolds composed of extracellular matrix have shown great promise as an inductive substrate to facilitate the constructive remodeling of gastrointestinal (GI) tissue damaged ...

Matrices: Theory and Applications

Statistical Applications for Equivariant Matrices

Solving linear system of equations Ax = b enters into many scientific applications. In this paper, we consider a special kind of linear systems, the matrix A is an equivariant matrix with respect to a finite group of permutations. Examples of this kind are special Toeplitz matrices, circulant matrices, and others. The equivariance property of A may be used to reduce the cost of computation for ...

Faster Subset Selection for Matrices and Applications

We study the following problem of subset selection for matrices: given a matrix X ∈ Rn×m (m > n) and a sampling parameter k (n ≤ k ≤ m), select a subset of k columns from X such that the pseudoinverse of the sampled matrix has as small a norm as possible. In this work, we focus on the Frobenius and the spectral matrix norms. We describe several novel (deterministic and randomized) approximation...
