Production of Human Endothelial Cells Free from Soluble Xenogeneic Antigens for Bioartificial Small Diameter Vascular Graft Endothelization. [PDF]
Biomed Res Int, 2015 Arterial bypass graft implantation remains the primary therapy for patients with advanced cardiovascular disease, but most lack adequate saphenous vein or other conduits for bypass procedures and would benefit from a bioartificial conduit. This study aimed to produce human endothelial cells (hECs) in large scale, free from xenogeneic antigens, to ...

Dragging human mesenchymal stem cells with the aid of supramolecular assemblies of single-walled carbon nanotubes, molecular magnets, and peptides in a magnetic field. [PDF]
Biomed Res Int, 2015 Human adipose‐derived stem cells (hASCs) are an attractive cell source for therapeutic applicability in diverse fields for the repair and regeneration of damaged or malfunctioning tissues and organs. There is a growing number of cell therapies using stem cells due to their characteristics of modulation of immune system and reduction of acute rejection.

Modeling and tuning of glucose oxidase‐catalase system incorporating dissolved oxygen concentration
Journal of Chemical Technology &Biotechnology, Volume 98, Issue 6, Page 1520-1531, June 2023., 2023 Abstract BACKGROUND Gluconic acid production by a glucose oxidase (GOx) and catalase (CAT) system has been proposed. However, the bioprocess optimal design and operation are limited by the lack of kinetic models of GOx involving oxygen as substrate. Herein, the GOx‐CAT system is modeled considering a continuous oxygen supply at a bioreactor lab scale ...

Nano Select, Volume 2, Issue 2, Page 346-356, February 2021., 2021 A thermometer based on single Nd3 + :Y2O3 nanoparticles is reported. It relies on the ratio of thermally coupled Nd3 + emission lines accessible by continuous‐wave upconversion under 880 nm or downconversion under 532 nm. The rate equation analysis lead to results that nicely agree with the experimental data. The system showed a relative sensitivity up
