CD45+ Cells Present Within Mesenchymal Stem Cell Populations Affect Network Formation of Blood-Derived Endothelial Outgrowth Cells.

BioResearch open access

Peters EB, Christoforou N, Moore E, West JL, Truskey GA.
PMID: 26309784
Biores Open Access. 2015 Jan 01;4(1):75-88. doi: 10.1089/biores.2014.0029. eCollection 2015.

Mesenchymal stem cells (MSCs) and endothelial progenitor cells (EPCs) represent promising cell sources for angiogenic therapies. There are, however, conflicting reports regarding the ability of MSCs to support network formation of endothelial cells. The goal of this study was...

Poly(ethylene glycol) Hydrogel Scaffolds Containing Cell-Adhesive and Protease-Sensitive Peptides Support Microvessel Formation by Endothelial Progenitor Cells.

Cellular and molecular bioengineering

Peters EB, Christoforou N, Leong KW, Truskey GA, West JL.
PMID: 27042236

The development of stable, functional microvessels remains an important obstacle to overcome for tissue engineered organs and treatment of ischemia. Endothelial progenitor cells (EPCs) are a promising cell source for vascular tissue engineering as they are readily obtainable and...

Hemiaminals as substrates for sulfur ylides: direct asymmetric syntheses of functionalised pyrrolidines and piperidines.

Chemical communications (Cambridge, England)

Kokotos CG, Aggarwal VK.
PMID: 16703139
Chem Commun (Camb). 2006 May 28;(20):2156-8. doi: 10.1039/b602226j. Epub 2006 Apr 13.

Phenyl stabilised chiral sulfur ylides react with five-membered-ring hemiaminals to give functionalised pyrrolidines directly with high enantioselectivity. The reaction can be diverted to give piperidines instead by isolation of the intermediate epoxide and treatment with TMSOTf.

Aminals as substrates for sulfur ylides: a synthesis of functionalized aziridines and N-heterocycles.

Organic letters

Kokotos CG, Aggarwal VK.
PMID: 17465558
Org Lett. 2007 May 24;9(11):2099-102. doi: 10.1021/ol070507f. Epub 2007 Apr 28.

Sulfur ylides stabilized by Ar, vinyl, or amide groups react with five-membered-ring tert-butylsulfinyl aminals to give functionalized chiral, nonracemic aziridines in high yield and with good selectivities (up to 15:1 trans:cis, up to >95:5 trans dr, always >95:5 cis...

Magnetic Resonance Measurement of Transient Shear Wave Propagation in a Viscoelastic Gel Cylinder.

Journal of the mechanics and physics of solids

Bayly PV, Massouros PG, Christoforou E, Sabet A, Genin GM.
PMID: 18568090
J Mech Phys Solids. 2008 May;56(5):2036-2049. doi: 10.1016/j.jmps.2007.10.012.

A magnetic resonance measurement technique was developed to characterize the transient mechanical response of a gel cylinder subjected to angular acceleration. The technique employs tagged magnetic resonance imaging (MRI) synchronized to periodic impact excitation of a bulk specimen. The...

Green Photo-Organocatalytic C-H Activation of Aldehydes: Selective Hydroacylation of Electron-Deficient Alkenes.

Chemistry (Weinheim an der Bergstrasse, Germany)

Papadopoulos GN, Voutyritsa E, Kaplaneris N, Kokotos CG.
PMID: 29194813
Chemistry. 2018 Feb 01;24(7):1726-1731. doi: 10.1002/chem.201705634. Epub 2018 Jan 04.

Selective C-H activation is an area of growing importance. Metal-free C-H activation of branched aldehydes mediating the hydroacylation of electron-deficient alkenes is an attractive transformation, but is limited by selectivity issues, especially in the case of α,α-disubstituted aldehydes. Herein,...

Photoorganocatalysis, small organic molecules and light in the service of organic synthesis: the awakening of a sleeping giant.

Organic & biomolecular chemistry

Sideri IK, Voutyritsa E, Kokotos CG.
PMID: 29888357
Org Biomol Chem. 2018 Jul 07;16(25):4596-4614. doi: 10.1039/c8ob00725j. Epub 2018 Jun 11.

Photocatalysis, the use of light to promote organic transformations, is a field of catalysis that has received limited attention despite existing for over 100 years. With the revolution of photoredox catalysis in 2008, the rebirth or awakening of the...

Development of Photocatalytic Coatings by Thermal Hydrolysis of TiCl.

Materials (Basel, Switzerland)

Christogerou A, Koumpouri D, Angelopoulos GN.
PMID: 32019232
Materials (Basel). 2020 Jan 30;13(3). doi: 10.3390/ma13030620.

The development of new, environmental friendly building materials with photocatalytic properties remain still on the top of the investigations both for academy and industry. The main drive is the increasing air pollution and the greenhouse gas emissions that have...
