INTRODUCTION: A number of studies reported on a possible increased risk of morbidity and mortality after coronary artery bypass grafting in patients with prior percutaneous coronary intervention.METHODS: A systematic review and meta-analysis of studies comparing the outcome of patients...

Configurational Behavior and Conductance of Alkanedithiol Molecular Wires from Accelerated Dynamics Simulations.

Journal of chemical theory and computation

Paz SA, Zoloff Michoff ME, Negre CF, Olmos-Asar JA, Mariscal MM, Sánchez CG, Leiva EP.

J Chem Theory Comput. 2012 Nov 13;8(11):4539-45. doi: 10.1021/ct3007327. Epub 2012 Oct 17.

An accelerated dynamics scheme is employed to sample the configurational space of a system consisting of an alkanedithiol molecule confined to the gap between a metal tip and a perfect metal surface. With this information and by means of...

How much hamstring graft needs to be in the femoral tunnel? A MOON cohort study.

European orthopaedics and traumatology

Mariscalco MW, Magnussen RA, Mitchell J, Pedroza AD, Jones MH, Andrish JT, Parker RD, Kaeding CC, Flanigan DC.
PMID: 25984246
Eur Orthop Traumatol. 2015 Mar 01;6(1):9-13. doi: 10.1007/s12570-014-0275-x.

BACKGROUND: Recent evidence that smaller hamstring graft diameter is associated with increased failure risk following anterior cruciate ligament (ACL) reconstruction has increased the popularity of graft configurations that increase graft diameter at the expense of graft length. A key...

Effects of water stress cycles on turgor maintenance processes in pear leaves (Pyrus communis).

Tree physiology

Marsal J, Girona J.
PMID: 14759856
Tree Physiol. 1997 May;17(5):327-33. doi: 10.1093/treephys/17.5.327.

Effects of water deficits on leaf turgor maintenance processes were analyzed for pear trees (Pyrus communis L. cv. "Barlett") grown in 120-liter containers. Four irrigation treatments were applied: a well-watered control treatment, a spring water stress cycle (Sp), a...

Collision as a way of forming bimetallic nanoclusters of various structures and chemical compositions.

The Journal of chemical physics

Mariscal MM, Dassie SA, Leiva EP.
PMID: 16292912
J Chem Phys. 2005 Nov 08;123(18):184505. doi: 10.1063/1.2104487.

In the present work, a new way to obtain bimetallic nanoclusters of different structures and chemical compositions is proposed, which is based on computer simulations. Collision processes between two metal clusters of different natures are simulated through molecular-dynamics simulations...

Atomistic computer simulations on the generation of bimetallic nanoparticles.

Faraday discussions

Mariscal MM, Oldani NA, Dassie SA, Leiva EP.
PMID: 18447011
Faraday Discuss. 2008;138:89-104; discussion 119-35, 433-4. doi: 10.1039/b706149h.

Computer simulations on the generation of bimetallic nanoparticles are presented in this work. Two different generation mechanisms are simulated: (a) cluster-cluster collision by means of atom dynamics simulations; and (b) nanoparticle growth from a previous seed through grand canonical...

IEEE Trans Ultrason Ferroelectr Freq Control. 2009 Sep;56(9):2023-6. doi: 10.1109/TUFFC.2009.1279.

The aim of this work is to obtain the geometry profile of a waveguide of continuous varying section, by inversing the experimental data. This determination is based on the use of the adiabatic behavior of guided waves. The geometry...

Anchoring sites to the STM tip can explain multiple peaks in single molecule conductance histograms.

Physical chemistry chemical physics : PCCP

Accelerated molecular dynamics and quantum conductance calculations are employed to shed light onto the electrochemical properties of the Au|1,8-octanedithiol|Au junction. Widely different contact geometries with varying degrees of roughness are examined. Strikingly, the two extreme situations considered in this...

Adult motor coordination requires strong coincident cortical excitatory input to hyperpolarized medium spiny neurons (MSNs), the dominant neuronal population of the striatum. However, cortical and subcortical neurons generate during development large ongoing patterns required for activity-dependent construction of networks....
