Beilstein J Org Chem. 2014 May 15;10:1129-34. doi: 10.3762/bjoc.10.112. eCollection 2014.

The development of a reliable procedure for the synthesis of the 16-glucoside and 16-sulfate of the resorcylic acid lactone (RAL) type compound zearalenone is presented. Different protective group strategies were considered and applied to enable the preparation of glucosides...

Detection of Botulinum Toxins A, B, E, and F in Foods by Endopep-MS.

Journal of agricultural and food chemistry

Kalb SR, Krilich JC, Dykes JK, Lúquez C, Maslanka SE, Barr JR.
PMID: 25578960
J Agric Food Chem. 2015 Feb 04;63(4):1133-1141. doi: 10.1021/jf505482b. Epub 2015 Jan 22.

Botulism is caused by exposure to botulinum neurotoxins (BoNTs). BoNTs are proteins secreted by some species of clostridia; these neurotoxins are known to interfere with nerve impulse transmission, thus causing paralysis. Botulism may be contracted through consumption of food...

Complications Related to Metal-on-Metal Articulation in Trapeziometacarpal Joint Total Joint Arthroplasty.

Journal of functional biomaterials

Frølich C, Hansen TB.
PMID: 26020592
J Funct Biomater. 2015 May 25;6(2):318-27. doi: 10.3390/jfb6020318.

Adverse reactions to metal-on-metal (MoM) prostheses are well known from total hip joint resurfacing arthroplasty with elevated serum chrome or cobalt, pain and pseudo tumor formation. It may, however, also be seen after total joint replacement of the trapeziometacarpal...

Neutrino-induced nucleosynthesis of A>64 nuclei: the nu p process.

Physical review letters

Fröhlich C, Martínez-Pinedo G, Liebendörfer M, Thielemann FK, Bravo E, Hix WR, Langanke K, Zinner NT.
PMID: 16712066
Phys Rev Lett. 2006 Apr 14;96(14):142502. doi: 10.1103/PhysRevLett.96.142502. Epub 2006 Apr 10.

We present a new nucleosynthesis process that we denote as the nu p process, which occurs in supernovae (and possibly gamma-ray bursts) when strong neutrino fluxes create proton-rich ejecta. In this process, antineutrino absorptions in the proton-rich environment produce...

Double-resonance polarization spectroscopy using modulation sidebands.

Optics letters

Mlynek J, Drake KH, Kersten G, Frölich D, Lange W.
PMID: 19701336
Opt Lett. 1981 Feb 01;6(2):87-9. doi: 10.1364/ol.6.000087.

A novel technique for ultrahigh-resolution laser spectroscopy is described. Coherence between atomic substates created by an amplitude-modulated light beam is monitored in transmission of a weak probe beam by polarizationselective optical heterodyne detection. As a demonstration, the technique is...

Characterization of pyrgeometers and the accuracy of atmospheric long-wave radiation measurements.

Applied optics

Philipona R, Fröhlich C, Betz C.
PMID: 21037701
Appl Opt. 1995 Mar 20;34(9):1598-605. doi: 10.1364/AO.34.001598.

A detailed characterization is performed to calibrate pyrgeometers, using a newly developed apparatus that contains a blackbody radiation source and the means to vary the temperatures of the pyrgeometer under testing. Calibration measurements cover the parameter space of radiation...

New determination of Rayleigh scattering in the terrestrial atmosphere.

Fröhlich C, Shaw GE.
PMID: 20221123
Appl Opt. 1980 Jun 01;19(11):1773-5. doi: 10.1364/AO.19.001773.

New Rayleigh-scattering optical thickness values for the terrestrial atmosphere in the 260 < lambda < 1500-nm wavelength range have been calculated using updated data on atmospheric optical parameters. The calculations include molecular scattering from water vapor and take into...

PURPOSE: This work determined if 2, 6-diisopropylphenol (propofol) selectively affects cerebral blood flow in regions associated with wakefulness.PROCEDURES: Cerebral blood flow (CBF) was measured with positron emission tomography (PET) using the 15O-water bolus technique in 10 subjects while awake...

4-[(Z)-2-(methylsulfanyl)ethenyl]-1-phenyl-1H-1,2,3-triazole: an order-disorder (OD) interpretation of twinning.

Acta Crystallogr C. 2011 Nov;67:o464-8. doi: 10.1107/S0108270111043083. Epub 2011 Oct 31.

The title compound, C(11)H(11)SN(3), crystallizes as twins with a twin volume fraction of 0.4232 (13). An order-disorder (OD) interpretation gives a plausible explanation of the crystallization behaviour. The structure is a polytype with a maximum degree of order (MDO)....
