Wound Closure After Port Implantation-a Randomized Controlled Trial Comparing Tissue Adhesive and Intracutaneous Suturing.

Saskia Witting, Maja Ingwersen, Thomas Lehmann, René Aschenbach, Niklas Eckardt, Jürgen Zanow, René Fahrner, Stephan Lotze, Reinhard Friedel, Mark Lenz, Claudia Schmidt, Diana Miguel, Laine Ludriksone, Ulf Teichgräber,

<h4>Background</h4>Wound healing after pectoral port implantation is a major factor determining the success or failure of the procedure. Infection and wound dehiscence can endanger the functionality of the port system and impede chemotherapy. The cosmetic result is important for patient satisfaction as well.<h4>Methods</h4>From August 2015 to July 2017, adult patients ... Read more >>

Communication: Probing the absolute configuration of chiral molecules at aqueous interfaces.

Stephan Lotze, Jan Versluis, Luuk L C Olijve, Luuk van Schijndel, Lech G Milroy, Ilja K Voets, Huib J Bakker,

We demonstrate that the enantiomers of chiral macromolecules at an aqueous interface can be distinguished with monolayer sensitivity using heterodyne-detected vibrational sum-frequency generation (VSFG). We perform VSFG spectroscopy with a polarization combination that selectively probes chiral molecular structures. By using frequencies far detuned from electronic resonances, we probe the chiral ...

Investigation of the Ice-Binding Site of an Insect Antifreeze Protein Using Sum-Frequency Generation Spectroscopy.

Konrad Meister, Stephan Lotze, Luuk L C Olijve, Arthur L DeVries, John G Duman, Ilja K Voets, Huib J Bakker,

We study the ice-binding site (IBS) of a hyperactive antifreeze protein from the beetle Dendroides canadensis (DAFP-1) using vibrational sum-frequency generation spectroscopy. We find that DAFP-1 accumulates at the air-water interface due to the hydrophobic character of its threonine-rich IBS while retaining its highly regular β-helical fold. We observe a ... Read more >>

Observation of ice-like water layers at an aqueous protein surface.

Konrad Meister, Simona Strazdaite, Arthur L DeVries, Stephan Lotze, Luuk L C Olijve, Ilja K Voets, Huib J Bakker,

We study the properties of water at the surface of an antifreeze protein with femtosecond surface sum frequency generation spectroscopy. We find clear evidence for the presence of ice-like water layers at the ice-binding site of the protein in aqueous solution at temperatures above the freezing point. Decreasing the temperature ...

Structure and dynamics of water in nanoscopic spheres and tubes.

Tibert H van der Loop, Niklas Ottosson, Stephan Lotze, Emmanuel Kentzinger, Thomas Vad, Wiebke F C Sager, Huib J Bakker, Sander Woutersen,

We study the reorientation dynamics of liquid water confined in nanometer-sized reverse micelles of spherical and cylindrical shape. The size and shape of the micelles are characterized in detail using small-angle x-ray scattering, and the reorientation dynamics of the water within the micelles is investigated using GHz dielectric relaxation spectroscopy ...

Influence of Förster-type energy transfer on the vibrational relaxation of anionic hydration shells.

Stephan Lotze, Huib J Bakker,

We study the influence of Förster energy transfer on the vibrational relaxation dynamics of anionic hydration shells by performing time-resolved mid-infrared spectroscopy on the OH-stretch vibration of water molecules in aqueous solutions of sodium iodide. We observe that the Förster energy transfer leads to a pronounced acceleration of the vibrational ... Read more >>

Structure and dynamics of water in nonionic reverse micelles: a combined time-resolved infrared and small angle x-ray scattering study.

Tibert H van der Loop, Matthijs R Panman, Stephan Lotze, Jing Zhang, Thomas Vad, Huib J Bakker, Wiebke F C Sager, Sander Woutersen,

We study the structure and reorientation dynamics of nanometer-sized water droplets inside nonionic reverse micelles (water/Igepal-CO-520/cyclohexane) with time-resolved mid-infrared pump-probe spectroscopy and small angle x-ray scattering. In the time-resolved experiments, we probe the vibrational and orientational dynamics of the O-D bonds of dilute HDO:H(2)O mixtures in Igepal reverse micelles as ... Read more >>
