Internal glow discharge-fourier transform ion cyclotron resonance mass spectrometry.

Journal of the American Society for Mass Spectrometry

Goodner KL, Milgram KE, Watson CH, Eyler JR, Dejsupa C, Barshick CM.
PMID: 24203606
J Am Soc Mass Spectrom. 1996 Sep;7(9):923-9. doi: 10.1016/1044-0305(96)00025-6.

A glow discharge (GD) ion source has been developed to work within the high magnetic field of a Fourier transform ion cyclotron resonance (FTICR) mass spectrometer. Characterization of this source revealed that the optimum operating voltage, pressure, and current...

Mutations that prevent or mimic persistent post-translational modifications of the histone H3 globular domain cause lethality and growth defects in Drosophila.

Epigenetics & chromatin

Graves HK, Wang P, Lagarde M, Chen Z, Tyler JK.
PMID: 26933451
Epigenetics Chromatin. 2016 Feb 29;9:9. doi: 10.1186/s13072-016-0059-3. eCollection 2016.

BACKGROUND: Understanding the function of histone post-translational modifications is the key to deciphering how genomic activities are regulated. Among the least well-understood histone modifications in vivo are those that occur on the surface of the globular domain of histones,...

Synthesis, structure, ultrafast kinetics, and light-induced dynamics of CuHETPHEN chromophores.

Dalton transactions (Cambridge, England : 2003)

Kohler L, Hayes D, Hong J, Carter TJ, Shelby ML, Fransted KA, Chen LX, Mulfort KL.
PMID: 26924711
Dalton Trans. 2016 Jun 14;45(24):9871-83. doi: 10.1039/c6dt00324a.

Five heteroleptic Cu(i)bis(phenanthroline) chromophores with distinct variation in the steric bulk at the 2,9-phenanthroline position were synthesized using the HETPHEN method, and their ground and excited state properties are described. Analysis of the crystal structures reveals a significant distortion...

Inference of Calmodulin's Ca.

Journal of chemical theory and computation

Westerlund AM, Harpole TJ, Blau C, Delemotte L.
PMID: 29144736
J Chem Theory Comput. 2018 Jan 09;14(1):63-71. doi: 10.1021/acs.jctc.7b00346. Epub 2017 Dec 06.

A free energy landscape estimation method based on the well-known Gaussian mixture model (GMM) is used to compare the efficiencies of thermally enhanced sampling methods with respect to regular molecular dynamics. The simulations are carried out on two binding...

On the definition of a confounder.

Annals of statistics

VanderWeele TJ, Shpitser I.
PMID: 25544784
Ann Stat. 2013 Feb;41(1):196-220. doi: 10.1214/12-aos1058.

The causal inference literature has provided a clear formal definition of confounding expressed in terms of counterfactual independence. The causal inference literature has not, however, produced a clear formal definition of a confounder, as it has given priority to...

Probing trapped ion energies via ion-molecule reaction kinetics: Quadrupole ion trap mass spectrometry.

Journal of the American Society for Mass Spectrometry

Basic C, Eyler JR, Yost RA.
PMID: 24234638
J Am Soc Mass Spectrom. 1992 Oct;3(7):716-26. doi: 10.1016/1044-0305(92)87084-C.

We present a detailed study of the energies of the ions stored in a quadrupole ion trap mass spectrometer (QITMS). Previous studies have shown that the rate constant, k, for the charge exchange reaction Ar(+) N(+) 2 →, N(+)...

Fragmentation pathways and structural characterization of 14 nerve agent compounds by electrospray ionization tandem mass spectrometry.

Journal of analytical toxicology

Housman KJ, Swift AT, Oyler JM.
PMID: 25519457
J Anal Toxicol. 2015 Mar;39(2):96-105. doi: 10.1093/jat/bku135. Epub 2014 Dec 16.

Organophosphate nerve agents (OPNAs) are some of the most widely used and proliferated chemical warfare agents. As evidenced by recent events in Syria, these compounds remain a serious military and terrorist threat to human health because of their toxicity...

Rapid Synthesis of Boc-2',6'-dimethyl-l-tyrosine and Derivatives and Incorporation into Opioid Peptidomimetics.

ACS medicinal chemistry letters

Bender AM, Griggs NW, Gao C, Trask TJ, Traynor JR, Mosberg HI.
PMID: 26713104
ACS Med Chem Lett. 2015 Oct 19;6(12):1199-203. doi: 10.1021/acsmedchemlett.5b00344. eCollection 2015 Dec 10.

The unnatural amino acid 2',6'-dimethyl-l-tyrosine has found widespread use in the development of synthetic opioid ligands. Opioids featuring this residue at the N-terminus often display superior potency at one or more of the opioid receptor types, but the availability...

Sensitivity analysis for direct and indirect effects in the presence of exposure-induced mediator-outcome confounders.

Epidemiology, biostatistics and public health

VanderWeele TJ, Chiba Y.
PMID: 25580387
Epidemiol Biostat Public Health. 2014;11(2). doi: 10.2427/9027.

Questions of mediation are often of interest in reasoning about mechanisms, and methods have been developed to address these questions. However, these methods make strong assumptions about the absence of confounding. Even if exposure is randomized, there may be...
