Probiotic‐Based Mineralized Living Materials to Produce Antimicrobial Yogurts

Advanced Healthcare Materials, EarlyView.
The self‐assembly and mineralization of collagen in the presence of probiotics produces hybrid living materials that hosts and protects the cells. Intra‐ and interfibrillar mineralization of collagen fibers, as occurring in bone, results, respectively, in a bulk and single‐cell protective layer of cells, that survive in simulated gastric conditions and,

Twisted Algebras of Multiplier Hopf ($^*$-)algebra [PDF]

arXiv, 2017
In this paper we study twisted algebras of multiplier Hopf ($^*$-)algebras which generalize all kinds of smash products such as generalized smash products, twisted smash products, diagonal crossed products, L-R-smash products, two-sided crossed products and two-sided smash products for the ordinary Hopf algebras appeared in [P-O].

Cholesterol Functionalized Nanoparticles Are Effective against Helicobacter pylori, the Gastric Bug: A Proof‐of‐Concept Study

Advanced Healthcare Materials, EarlyView.
Helicobacter pylori gastric infection is widespread and recurrency is common, fuelled by bacterial resistance to antibiotics. Therefore, specific and noninducing resistance alternative treatments are an urgent need. Taking advantage of this gastric pathogen auxotrophy for cholesterol, a “trojan horse” strategy for H.

A Dual‐Layer Hydrogel Barrier Integrating Bio‐Adhesive and Anti‐Adhesive Properties Prevents Postoperative Abdominal Adhesions

Advanced Healthcare Materials, EarlyView.
A new dual‐layer hydrogel barrier for preventing postoperative abdominal adhesions is developed. The inner layer, consisting of polyethyleneimine (PEI) and thioctic acid (TA), enhanced adhesion to moist tissues. The outer layer combines zwitterionic, thermoresponsive hyaluronic acid with anti‐inflammatory epigallocatechin gallate (EGCG) and forms a ...

Ultrahigh Specific Strength by Bayesian Optimization of Carbon Nanolattices

Advanced Materials, EarlyView.
Multi‐objective Bayesian optimization algorithm designs high‐strength nanolattices made of pyrolytic carbon which offer the compressive strength of carbon steel at the density of Styrofoam. This study combines machine learning with nanoscale strengthening and nanoscale 3D printing to achieve unattained material properties with millimeter scalability ...

Natural Connections on Riemannian Product Manifolds [PDF]

arXiv, 2011
A Riemannian almost product manifold with integrable almost product structure is called a Riemannian product manifold. In the present paper the natural connections on such manifolds are studied, i.e. the linear connections preserving the almost product structure and the Riemannian metric.

Non‐Saccharomyces and Saccharomyces strains co‐fermentation increases acetaldehyde accumulation: effect on anthocyanin‐derived pigments in Tannat red wines

Yeast, 2016
During fermentation, Saccharomyces cerevisiae releases into the medium secondary metabolic products, such as acetaldehyde, able to react with anthocyanins, producing more stable derived pigments.

Tensor Product of Polygonal Cell Complexes [PDF]

arXiv, 2017
We introduce the tensor product of polygonal cell complexes, which interacts nicely with the tensor product of link graphs of complexes. We also develop the unique factorization property of polygonal cell complexes with respect to the tensor product, and study the symmetries of tensor products of polygonal cell complexes.
