Snowball: strain aware gene assembly of metagenomes.

Bioinformatics (Oxford, England)

Gregor I, Schönhuth A, McHardy AC.
PMID: 27587685
Bioinformatics. 2016 Sep 01;32(17):i649-i657. doi: 10.1093/bioinformatics/btw426.

MOTIVATION: Gene assembly is an important step in functional analysis of shotgun metagenomic data. Nonetheless, strain aware assembly remains a challenging task, as current assembly tools often fail to distinguish among strain variants or require closely related reference genomes...

Absolute Photoluminescence Quantum Yield Measurement in a Complex Nanoscopic System with Multiple Overlapping States.

The journal of physical chemistry letters

Karedla N, Enderlein J, Gregor I, Chizhik AI.
PMID: 26274471
J Phys Chem Lett. 2014 Apr 03;5(7):1198-202. doi: 10.1021/jz500221t. Epub 2014 Mar 21.

Using a metal nanocavity, we measure absolute values of the photoluminescence quantum yield in a mixture of different types of chromophores (dye molecules and semiconductor nanocrystals). We show that measurements can be performed in an attoliter volume, both in...

[The optimal diagnostic approach in myocardial infarct].

Vnitrni lekarstvi

Widimský P, Gregor P, Dvorák J, Sládková T, Herold M, Jirmár R, Hrdlicka S.
PMID: 8506663
Vnitr Lek. 1993 Feb;39(2):160-5.

In the submitted review the authors discuss rational criteria for the diagnosis of myocardial infarction, indications for thrombolysis, coronarography and possibly PTCA, the method of indirect (non-invasive) assessment of an occluded coronary artery and the most frequent mistakes in...

Cardioprotective effects of adenosine transport inhibition during reversible ischaemia in patients with coronary artery disease.

International journal of cardiovascular interventions

Ottervanger JP, Gregor P, Widimsky P, Zijlstra F, Kluiver EP, Hof AW, Suryapranata H.
PMID: 12623587
Int J Cardiovasc Intervent. 1999;2(3):181-186. doi: 10.1080/acc.2.3.181.186.

BACKGROUND: Adenosine plays a major role in protecting ischaemic myocardium and may potentiate ischaemic preconditioning. Nucleosine transport inhibition may enhance these favourable effects. DESIGN: Randomized, double blind, placebo controlled study, to investigate the haemodynamic and cardioprotective effects of nucleoside...

Probing nanoscale surface enhanced Raman-scattering fluctuation dynamics using correlated AFM and confocal ultramicroscopy.

Ultramicroscopy

Suh YD, Schenter GK, Zhu L, Lu HP.
PMID: 12801661
Ultramicroscopy. 2003 Oct-Nov;97(1):89-102. doi: 10.1016/S0304-3991(03)00033-0.

We have studied the laser-excitation-intensity-dependent and Ag-nanocluster interstitial-site-dependent SERS intensity fluctuations under low molecule surface coverage of rhodamine 6G and cytochrome c. A new two-channel photon time-stamping system coupled with atomic force microscopic (AFM), Raman spectroscopic, and imaging microscopy...

Molecular simulation analysis and X-ray absorption measurement of Ca2+, K+ and Cl- ions in solution.

The journal of physical chemistry. B

Dang LX, Schenter GK, Glezakou VA, Fulton JL.
PMID: 17125322
J Phys Chem B. 2006 Nov 30;110(47):23644-54. doi: 10.1021/jp064661f.

This paper presents recent advances in the use of molecular simulations and extended X-ray absorption fine structure (EXAFS) spectroscopy, which enable us to understand solvated ions in solution. We report and discuss the EXAFS spectra and related properties governing...

Optical saturation in fluorescence correlation spectroscopy under continuous-wave and pulsed excitation.

Chemphyschem : a European journal of chemical physics and physical chemistry

Gregor I, Patra D, Enderlein J.
PMID: 15688660
Chemphyschem. 2005 Jan;6(1):164-70. doi: 10.1002/cphc.200400319.

A detailed theoretical and experimental study of the dependence of fluorescence correlation measurements on optical excitation power due to optical saturation effects is presented. It is shown that the sensitivity of a fluorescence correlation measurement on excitation power becomes...

Helium diffusion through H2O and D2O amorphous ice: observation of a lattice inverse isotope effect.

Physical review letters

Daschbach JL, Schenter GK, Ayotte P, Smith RS, Kay BD.
PMID: 15169458
Phys Rev Lett. 2004 May 14;92(19):198306. doi: 10.1103/PhysRevLett.92.198306. Epub 2004 May 14.

The diffusion of He through both H2O and D2O amorphous solid water (ASW) has been measured between 55 and 110 K. We find the diffusion rate is dependent on the isotopic composition of the ASW lattice. This lattice isotope...
