Atomically thin quantum light-emitting diodes.

Nature communications

Palacios-Berraquero C, Barbone M, Kara DM, Chen X, Goykhman I, Yoon D, Ott AK, Beitner J, Watanabe K, Taniguchi T, Ferrari AC, Atatüre M.
PMID: 27667022
Nat Commun. 2016 Sep 26;7:12978. doi: 10.1038/ncomms12978.

Transition metal dichalcogenides are optically active, layered materials promising for fast optoelectronics and on-chip photonics. We demonstrate electrically driven single-photon emission from localized sites in tungsten diselenide and tungsten disulphide. To achieve this, we fabricate a light-emitting diode structure...

Pharmacological Intervention in Hepatic Stellate Cell Activation and Hepatic Fibrosis.

Frontiers in pharmacology

Schon HT, Bartneck M, Borkham-Kamphorst E, Nattermann J, Lammers T, Tacke F, Weiskirchen R.
PMID: 26941644
Front Pharmacol. 2016 Feb 24;7:33. doi: 10.3389/fphar.2016.00033. eCollection 2016.

The activation and transdifferentiation of hepatic stellate cells (HSCs) into contractile, matrix-producing myofibroblasts (MFBs) are central events in hepatic fibrogenesis. These processes are driven by autocrine- and paracrine-acting soluble factors (i.e., cytokines and chemokines). Proof-of-concept studies of the last...

Short- and long-term experience in pulmonary vein segmental ostial ablation for paroxysmal atrial fibrillation.

Indian pacing and electrophysiology journal

Pürerfellner H, Aichinger J, Martinek M, Nesser HJ, Janssen J.
PMID: 16943889
Indian Pacing Electrophysiol J. 2006 Jan 01;6(1):6-16.

INTRODUCTION: Segmental ostial pulmonary vein isolation (PVI) is considered a potentially curative therapeutic approach in the treatment of paroxysmal atrial fibrillation (PAF). There is only limited data available on the long-term effect of this procedure.METHODS: Patients (Pts) underwent a...

Cytokinin antagonist activity of substituted phenethylamines in plant cell culture.

Plant physiology

Christou P, Barton KA.
PMID: 16666583
Plant Physiol. 1989 Feb;89(2):564-8. doi: 10.1104/pp.89.2.564.

A series of structurally related substituted phenethylamines shows extreme toxicity toward wild-type callus tissue cultures of tobacco (Nicotiana tabacum), soybean (Glycine max), corn (Zea mays), and sunflower (Helianthus annuus L.), but tobacco crown gall cultures are resistant to the...

PMID: 20461276
Chem Commun (Camb). 2010 Jun 28;46(24):4387-9. doi: 10.1039/c002725a. Epub 2010 May 12.

The concept of using ascorbic acid as a mediator/ reducing agent in a Cu(I) catalyzed process is introduced and further demonstrated on a cross-coupling reaction of aryl iodides with disulfides.

Rate of precipitation of calcium phosphate on heated surfaces.

Biotechnology progress

Barton KP, Chapman TW, Lund D.
PMID: 20568134
Biotechnol Prog. 1985 Mar;1(1):39-45. doi: 10.1002/btpr.5420010109.

Fouling of a heated stainless steel surface by calcium phosphate precipitation has been studied in an annular flow apparatus, instrumented to provide a constant heat flux while measuring local metal-surface temperatures. Models of the heat and mass-transfer boundary layers...

Vasointestinal peptide metabolism plays a key physiological role in multimodular levels of vasodilatory, smooth muscle cell proliferative, parenchymal, and inflammatory lung reactions. In animal studies, vasointestinal peptide relaxes isolated pulmonary arterial segments from several mammalian species in vitro and...

Influence of Surface-Active Trace Impurities on the Surface Properties of Aqueous Solutions of Oligoethylene Glycol Monooctyl Ethers.
