Dynamic Nuclear Polarization and the Paradox of Quantum Thermalization.

Physical review letters

De Luca A, Rosso A.
PMID: 26340169
Phys Rev Lett. 2015 Aug 21;115(8):080401. doi: 10.1103/PhysRevLett.115.080401. Epub 2015 Aug 20.

Dynamic nuclear polarization (DNP) is to date the most effective technique to increase the nuclear polarization opening disruptive perspectives for medical applications. In a DNP setting, the interacting spin system is quasi-isolated and brought out of equilibrium by microwave...

PMID: 26423990
Lancet HIV. 2014 Nov;1(2):e85-93. doi: 10.1016/S2352-3018(14)70021-9. Epub 2014 Oct 14.

BACKGROUND: With continued roll-out of antiretroviral therapy (ART) in resource-limited settings, evidence is emerging of increasing levels of transmitted drug-resistant HIV. We aimed to compare the effectiveness and cost-effectiveness of different potential public health responses to substantial levels of...

Therapeutic Approaches to Genetic Ion Channelopathies and Perspectives in Drug Discovery.

Frontiers in pharmacology

Imbrici P, Liantonio A, Camerino GM, De Bellis M, Camerino C, Mele A, Giustino A, Pierno S, De Luca A, Tricarico D, Desaphy JF, Conte D.
PMID: 27242528
Front Pharmacol. 2016 May 10;7:121. doi: 10.3389/fphar.2016.00121. eCollection 2016.

In the human genome more than 400 genes encode ion channels, which are transmembrane proteins mediating ion fluxes across membranes. Being expressed in all cell types, they are involved in almost all physiological processes, including sense perception, neurotransmission, muscle...

Parachute Jumping Induces More Sympathetic Activation Than Cortisol Secretion in First-Time Parachutists.

Asian journal of sports medicine

Messina G, Chieffi S, Viggiano A, Tafuri D, Cibelli G, Valenzano A, Triggiani AI, Messina A, De Luca V, Monda M.
PMID: 27217924
Asian J Sports Med. 2016 Mar 08;7(1):e26841. doi: 10.5812/asjsm.26841. eCollection 2016 Mar.

BACKGROUND: The word "stress" describes the status of the body affected by external or internal forces, or "stressors", threatening to alter its dynamic balance or homeostasis. The adaptive changes which occur in reply to stressors are either behavioral or...

Broadband optical transparency in plasmonic nanocomposite polymer films via exciton-plasmon energy transfer.

Optics express

Dhama R, Rashed AR, Caligiuri V, El Kabbash M, Strangi G, De Luca A.
PMID: 27410615
Opt Express. 2016 Jun 27;24(13):14632-41. doi: 10.1364/OE.24.014632.

Inherent absorptive losses affect the performance of all plasmonic devices, limiting their fascinating applications in the visible range. Here, we report on the enhanced optical transparency obtained as a result of the broadband mitigation of optical losses in nanocomposite...

Right ventricle chamber of young trained athletes: morphology and function.

Asian journal of sports medicine

De Luca A, Stefani L, Galanti G.
PMID: 24800003
Asian J Sports Med. 2013 Dec;4(4):281-8. doi: 10.5812/asjsm.34248. Epub 2013 Jun 25.

PURPOSE: The study of the right ventricular (RV) chamber has been recently improved by use of the 3D method. In young asymptomatic trained athletes, RV is not routinely investigated if not in suspected disease. This study is designed to...

Creation of a Metabolic Sink for Tryptophan Alters the Phenylpropanoid Pathway and the Susceptibility of Potato to Phytophthora infestans.

The Plant cell

Yao K, De Luca V, Brisson N.
PMID: 12242360
Plant Cell. 1995 Nov;7(11):1787-1799. doi: 10.1105/tpc.7.11.1787.

The creation of artificial metabolic sinks in plants by genetic engineering of key branch points may have serious consequences for the metabolic pathways being modified. The introduction into potato of a gene encoding tryptophan decarboxylase (TDC) isolated from Catharanthus...

Observation of cancellation and second light-induced Fréedericksz transition in nematic liquid crystals.

Optics letters

De Luca A, Nersisyan S, Umeton C.
PMID: 12656500
Opt Lett. 2003 Jan 15;28(2):108-10. doi: 10.1364/ol.28.000108.

We describe the observation of a new phenomenon: the cancellation of molecular reorientation that has been achieved in nematic liquid crystals acted on by two competing (pulsed) light beams. The effect is unstable: Starting from the cancellation condition, we...

Developmental Regulation of Enzymes of Indole Alkaloid Biosynthesis in Catharanthus roseus.

Plant physiology

De Luca V, Fernandez JA, Campbell D, Kurz WG.
PMID: 16665928
Plant Physiol. 1988 Feb;86(2):447-50. doi: 10.1104/pp.86.2.447.

Developing seedlings of Catharanthus roseus were analyzed for appearance of tryptophan decarboxylase (TDC), strictosidine synthase (SS), N-methyltransferase (NMT) and O-acetyltransferase (DAT) enzyme activities. SS enzyme activity appeared early after germination and was present throughout most of the developmental study....

A long-period, violently variable X-ray source in a young supernova remnant.

Observations with the Newton X-ray Multimirror Mission satellite show a strong periodic modulation at 6.67 +/- 0.03 hours of the x-ray source at the center of the 2000-year-old supernova remnant RCW 103. No fast pulsations are visible. If genetically...

Direct measurement of surface-induced orientational order parameter profile above the nematic-isotropic phase transition temperature.
