Popescu B, Rahman H, Kleinekathöfer U.
PMID: 26845380
J Phys Chem A. 2016 May 19;120(19):3270-7. doi: 10.1021/acs.jpca.5b12237. Epub 2016 Feb 12.

To determine the dynamics of a molecular aggregate under the influence of a strongly time-dependent perturbation within a dissipative environment is still, in general, a challenge. The time-dependent perturbation might be, for example, due to external fields or explicitly...

A Toolkit for Orthogonal and in vivo Optical Manipulation of Ionotropic Glutamate Receptors.

Frontiers in molecular neuroscience

Levitz J, Popescu AT, Reiner A, Isacoff EY.
PMID: 26869877
Front Mol Neurosci. 2016 Feb 02;9:2. doi: 10.3389/fnmol.2016.00002. eCollection 2016.

The ability to optically manipulate specific neuronal signaling proteins with genetic precision paves the way for the dissection of their roles in brain function, behavior, and disease. Chemical optogenetic control with photoswitchable tethered ligands (PTLs) enables rapid, reversible and...

Central pancreatectomy: an oncologically safe option to treat metastases of other neoplasms of the mid-portion of the pancreas?.

Annals of hepato-biliary-pancreatic surgery

Dumitrascu T, Scarlat A, Ionescu M, Popescu I.
PMID: 28567450
Ann Hepatobiliary Pancreat Surg. 2017 May;21(2):76-79. doi: 10.14701/ahbps.2017.21.2.76. Epub 2017 May 23.

BACKGROUNDS/AIMS: Standard pancreatic resections are the current approach for patients with resectable, isolated pancreatic metastases of other neoplasms. However, the role of parenchyma-sparing pancreatectomies for such pathology is poorly investigated. The aim of the present study is to assess...

Collaboration Networks in Applied Conservation Projects across Europe.

The main funding instrument for implementing EU policies on nature conservation and supporting environmental and climate action is the LIFE Nature programme, established by the European Commission in 1992. LIFE Nature projects (>1400 awarded) are applied conservation projects in...

Intramolecular Communication in Anionic Oxidized Phosphanes through a Chelated Proton.

Chemistry (Weinheim an der Bergstrasse, Germany)

Popescu AR, Rojo I, Teixidor F, Sillanpää R, Viñas C.
PMID: 25926362
Chemistry. 2015 Jun 01;21(23):8613-25. doi: 10.1002/chem.201500307. Epub 2015 Apr 29.

Oxidation of the 1,2-(PR2 )2 -1,2-closo-C2 B10 H10 (R=Ph, iPr) platform with hydrogen peroxide in acetone is a two-step procedure in which partial deboronation of the closo cluster and oxidation of the phosphorus atoms occur. Based on NMR spectroscopic...

Whole body bone tissue and cardiovascular risk in rheumatoid arthritis.

Journal of osteoporosis

Popescu C, Bojincă V, Opriş D, Ionescu R.
PMID: 24808969
J Osteoporos. 2014;2014:465987. doi: 10.1155/2014/465987. Epub 2014 Apr 08.

Introduction. Atherosclerosis and osteoporosis share an age-independent bidirectional correlation. Rheumatoid arthritis (RA) represents a risk factor for both conditions. Objectives. The study aims to evaluate the connection between the estimated cardiovascular risk (CVR) and the loss of bone tissue...

Inverse scattering solutions using low-coherence light.

Optics letters

Zhou R, Kim T, Goddard LL, Popescu G.
PMID: 25078211
Opt Lett. 2014 Aug 01;39(15):4494-7. doi: 10.1364/OL.39.004494.

We present a new wave-vector-space approach for solving inverse scattering problems. In our formulation, the theories for diffraction tomography and coherence gating are combined to explain 3D reconstruction with low-coherence light. Specifically, we apply this method to solve the...
