Effect of Misoprostol on Mesangial Cell Growth and Collagen Metabolism.

American journal of therapeutics

Dumler F, Cortes P, Riser B.
PMID: 11854809
Am J Ther. 1995 Dec;2(12):922-927. doi: 10.1097/00045391-199512000-00004.

Independent of etiology, progressive chronic renal failure is characterized by accumulation of mesangial matrix and collagenous materials leading to glomerular sclerosis and closure. Pharmacologic intervention aimed at ameliorating this process has significant potential for substantial clinical benefit. We, therefore,...

Microcrystalline cellulose as a carrier for hydrophobic photosensitizers in water.

Samples of pheophorbide-a adsorbed on microcrystalline cellulose, which have been previously characterized in the solid state (M.G. Lagorio, E. San Roman, A. Zeug, J. Zimmermann and B. Röder, Phys. Chem. Chem. Phys., 2001, 3. 1524-1529), were washed with water,...

Photogeneration of singlet oxygen by humic substances: comparison of humic substances of aquatic and terrestrial origin.

Photochemical & photobiological sciences : Official journal of the European Photochemistry Association and the European Society for Photobiology

Paul A, Hackbarth S, Vogt RD, Röder B, Burnison BK, Steinberg CE.
PMID: 14993944
Photochem Photobiol Sci. 2004 Mar;3(3):273-80. doi: 10.1039/b312146a. Epub 2004 Jan 09.

The singlet oxygen (1(O2)) luminescence of 27 isolated humic substances (HS), natural organic matter, ultrafiltrates, and the synthetic fulvic acid HS1500 has been investigated by time-resolved spectroscopy in buffered D(2)O. The samples include both reverse osmosis isolates from lakes...

Sensory recalibration integrates information from the immediate and the cumulative past.

Scientific reports

Bruns P, Röder B.
PMID: 26238089
Sci Rep. 2015 Aug 04;5:12739. doi: 10.1038/srep12739.

Vision usually provides the most accurate and reliable information about the location of objects in our environment, and thus serves as a reference for recalibrating auditory spatial maps. Recent studies have shown that recalibration does not require accumulated evidence...

Short-term visual deprivation reduces interference effects of task-irrelevant facial expressions on affective prosody judgments.

Frontiers in integrative neuroscience

Fengler I, Nava E, Röder B.
PMID: 25954166
Front Integr Neurosci. 2015 Apr 22;9:31. doi: 10.3389/fnint.2015.00031. eCollection 2015.

Several studies have suggested that neuroplasticity can be triggered by short-term visual deprivation in healthy adults. Specifically, these studies have provided evidence that visual deprivation reversibly affects basic perceptual abilities. The present study investigated the long-lasting effects of short-term...

Degenerate optical parametric amplifier delivering sub 30 fs pulses with 2GW peak power.

Optics express

Hädrich S, Rothhardt J, Röser F, Gottschall T, Limpert J, Tünnermann A.
PMID: 19030067
Opt Express. 2008 Nov 24;16(24):19812-20. doi: 10.1364/oe.16.019812.

Degenerated optical parametric amplification (OPA) is a well known technique to achieve broadband amplification necessary to generate ultrashort pulses. Here we present a parametric amplifier pumped by the frequency doubled output of a state-of-the-art fiber chirped pulse amplification system...

Linear absorbance of the pheophorbide-a butanediamine dendrimer P(4) in solution: computational studies using a mixed quantum classical methodology.

The Journal of chemical physics

Zhu H, May V, Röder B, Renger T.
PMID: 18433275
J Chem Phys. 2008 Apr 21;128(15):154905. doi: 10.1063/1.2890721.

The linear absorbance of a particular chromophore complex P(4) dissolved in ethanol is computed. P(4) is formed by a butanediamine dendrimer to which four pheophorbide-a molecules are covalently linked. The computations utilize a mixed quantum classical methodology and different...

High-power rod-type photonic crystal fiber laser.

Optics express

Limpert J, Deguil-Robin N, Manek-Hönninger I, Salin F, Röser F, Liem A, Schreiber T, Nolte S, Zellmer H, Tünnermann A, Broeng J, Petersson A, Jakobsen C.
PMID: 19494970
Opt Express. 2005 Feb 21;13(4):1055-8. doi: 10.1364/opex.13.001055.

We report on a novel ytterbium-doped fiber design that combines the advantages of rod and fiber gain media. The fiber design has outer dimensions of a rod laser, meaning a diameter in the range of a few millimeters and...

Stress-induced birefringence in large-mode-area micro-structured optical fibers.

Optics express

Schreiber T, Schultz H, Schmidt O, Röser F, Limpert J, Tünnermann A.
PMID: 19495270
Opt Express. 2005 May 16;13(10):3637-46. doi: 10.1364/opex.13.003637.

We report on detailed numerical investigation of stress-induced birefringence in micro-structured solid-core optical fibers. The stress is induced either by external forces or stress applying parts inside the fiber. Both methods lead to different stress distributions where screening as...

Enolate structure and electron affinity.

The journal of physical chemistry. A

Walthall DA, Karty JM, Römer B, Ursini O, Brauman JI.
PMID: 16834281

Photodetachment cross sections for a series of cyclic enolates were measured using a continuous wave (CW) ion cyclotron resonance instrument to generate and detect the ions. We report electron affinities for the radicals corresponding to the removal of the...

Adventure tourism and schistosomiasis: serology and clinical findings in a group of Danish students after white-water rafting in Uganda.

Front Hum Neurosci. 2020 Mar 17;14:72. doi: 10.3389/fnhum.2020.00072. eCollection 2020.

Working memory (WM) refers to the temporary retention and manipulation of information, and its capacity is highly susceptible to training. Yet, the neural mechanisms that allow for increased performance under demanding conditions are not fully understood. We expected that...
