A Historical View of Motion Sickness-A Plague at Sea and on Land, Also with Military Impact.

Frontiers in neurology

Huppert D, Benson J, Brandt T.
PMID: 28421029
Front Neurol. 2017 Apr 04;8:114. doi: 10.3389/fneur.2017.00114. eCollection 2017.

Seasickness and its triggers, symptoms, and preventive measures were well known in antiquity. This chapter is based on an analysis of descriptions of motion sickness, in particular seasickness, in ancient Greek, Roman, and Chinese literature. A systematic search was...

Photoelectron spectrometer for attosecond spectroscopy of liquids and gases.

The Review of scientific instruments

Jordan I, Huppert M, Brown MA, van Bokhoven JA, Wörner HJ.
PMID: 26724045
Rev Sci Instrum. 2015 Dec;86(12):123905. doi: 10.1063/1.4938175.

A new apparatus for attosecond time-resolved photoelectron spectroscopy of liquids and gases is described. It combines a liquid microjet source with a magnetic-bottle photoelectron spectrometer and an actively stabilized attosecond beamline. The photoelectron spectrometer permits venting and pumping of...

Metal Linkage Effects on Ultrafast Energy Transfer.

Chemistry (Weinheim an der Bergstrasse, Germany)

Dekkiche H, Buisson A, Langlois A, Karsenti PL, Ruhlmann L, Ruppert R, Harvey P.
PMID: 27333487
Chemistry. 2016 Jul 18;22(30):10484-93. doi: 10.1002/chem.201601322. Epub 2016 Jun 22.

We report the preparation of several new porphyrin homodimers bridged by a platinum(II) ion in which very intense electronic communication through the coordination link occurs. Moreover, the synthesis of a new porphyrin dyad and its photophysical properties are reported....

Does core mobility of lumbar total disc arthroplasty influence sagittal and frontal intervertebral displacement? Radiologic comparison with fixed-core prosthesis.

SAS journal

Delécrin J, Allain J, Beaurain J, Steib JP, Chataigner H, Aubourg L, Huppert J, Ameil M, Nguyen JM.
PMID: 25802632
SAS J. 2009 Sep 01;3(3):91-9. doi: 10.1016/j.esas.2009.09.001. eCollection 2009.

BACKGROUND: An artificial disc prosthesis is thought to restore segmental motion in the lumbar spine. However, it is reported that disc prosthesis can increase the intervertebral translation (VT). The concept of the mobile-core prosthesis is to mimic the kinematic...

Methodological framework to identify possible adverse drug reactions using population-based administrative data.

F1000Research

Sauer B, Nebeker J, Shen S, Rupper R, West S, Shinogle JA, Xu W, Lohr KN, Samore M.
PMID: 26180631
F1000Res. 2014 Oct 29;3:258. doi: 10.12688/f1000research.4816.1. eCollection 2014.

PURPOSE: We present a framework for detecting possible adverse drug reactions (ADRs) using the Utah Medicaid administrative data. We examined four classes of ADRs associated with treatment of dementia by acetylcholinesterase inhibitors (AChEIs): known reactions (gastrointestinal, psychological disturbances), potential...

Dynamic filtering improves attentional state prediction with fNIRS.

Biomedical optics express

Harrivel AR, Weissman DH, Noll DC, Huppert T, Peltier SJ.
PMID: 27231602
Biomed Opt Express. 2016 Feb 23;7(3):979-1002. doi: 10.1364/BOE.7.000979. eCollection 2016 Mar 01.

Brain activity can predict a person's level of engagement in an attentional task. However, estimates of brain activity are often confounded by measurement artifacts and systemic physiological noise. The optimal method for filtering this noise - thereby increasing such...

B Cells Are Multifunctional Players in Multiple Sclerosis Pathogenesis: Insights from Therapeutic Interventions.

Frontiers in immunology

Claes N, Fraussen J, Stinissen P, Hupperts R, Somers V.
PMID: 26734009
Front Immunol. 2015 Dec 21;6:642. doi: 10.3389/fimmu.2015.00642. eCollection 2015.

Multiple sclerosis (MS) is a severe disease of the central nervous system (CNS) characterized by autoimmune inflammation and neurodegeneration. Historically, damage to the CNS was thought to be mediated predominantly by activated pro-inflammatory T cells. B cell involvement in...

Excited state proton transfer in reverse micelles.

Journal of the American Chemical Society

Cohen B, Huppert D, Solntsev KM, Tsfadia Y, Nachliel E, Gutman M.
PMID: 12071764
J Am Chem Soc. 2002 Jun 26;124(25):7539-47. doi: 10.1021/ja012646c.

The aqueous phase of water/AOT reversed micelles having varying diameters was probed by a single free diffusing proton that was released form a hydrophilic photoacid molecule (2-naphthol-6,8-disulfonate). The fluorescence decay signals were reconstructed through the geminate recombination algorithm, accounting...

Colorful Friedel-Crafts chemistry of meso-tetraarylporphyrins. An unexpected route to porphyrinic spiro dimers.

Organic letters

Jeandon C, Ruppert R, Richeter S, Callot HJ.
PMID: 12713305
Org Lett. 2003 May 01;5(9):1487-9. doi: 10.1021/ol0342554.

Under Friedel-Crafts conditions, meso-tetraarylporphyrins give porphyrin spiro dimers in good yield. This reaction involves acylation, acid-catalyzed cyclization, and dimerization. A stable dimer possessing three additional six-membered rings could be isolated and its structure determined. By modifying the substrate and...

Nonaromatic corroles: regioselectivity of electrophilic substitution.

The Journal of organic chemistry

Ruppert R, Jeandon C, Callot HJ.
PMID: 18095708
J Org Chem. 2008 Jan 18;73(2):694-700. doi: 10.1021/jo702321h. Epub 2007 Dec 21.

Ring contraction of nickel meso-tetraarylporphyrins produced nonaromatic divalent corroles bearing a benzoyloxy function. We investigated their reactivity under electrophilic conditions: formylation, halogenation, nitration. We also found that the benzoate function could be eliminated to afford deoxocorroles, and we tested...

Palliat Med. 2009 Jun;23(4):369-73. doi: 10.1177/0269216309102987. Epub 2009 Feb 27.

Palliative care medical emergencies as a consequence of advanced cancer account for approximately 3% of all prehospital emergency cases. Therefore, prehospital emergency physicians (EP) are confronted with 'end of life decisions'. No educational content exists concerning palliative medicine in...
