Homocysteine and folate plasma concentrations in mother and baby at delivery after pre-eclamptic or normotensive pregnancy: Influence of parity.

Pregnancy hypertension

Mistry HD, Mather J, Ramsay MM, Kurlak LO, Symonds ME, Broughton Pipkin F.
PMID: 26104496
Pregnancy Hypertens. 2011 Apr;1(2):150-5. doi: 10.1016/j.preghy.2011.01.006. Epub 2011 Feb 12.

UNLABELLED: Pre-eclampsia affects between 2% and 7% of all pregnant women, contributing to perinatal and maternal morbidity. There are conflicting data on plasma homocysteine and folate in pre-eclampsia, and little about fetal concentrations.OBJECTIVES: Firstly, to compare the concentrations of...

Picogram determination of "earthly-musty" odorous compounds in water using modified closed loop stripping analysis and large volume injection GC/MS.

Analytical chemistry

Malleret L, Bruchet A, Hennion MC.
PMID: 11321298
Anal Chem. 2001 Apr 01;73(7):1485-90. doi: 10.1021/ac001010l.

"Earthy-musty" off-flavor problems in water samples are due to organic compounds present at the sub-part-per-trillion level. Numerous analytical methods such as purge and trap, liquid/liquid extraction, and closed-loop stripping analysis (CLSA) followed by GC/MS analysis have been used to...

Internet hand x-rays: A comparison of joint space narrowing and erosion scores (Sharp/Genant) of plain versus digitized x-rays in rheumatoid arthritis patients.

BMC musculoskeletal disorders

Arbillaga HO, Montgomery GP, Cabarrus LP, Watson MM, Martin L, Edworthy SM.
PMID: 11980582
BMC Musculoskelet Disord. 2002 Apr 30;3:13. doi: 10.1186/1471-2474-3-13. Epub 2002 Apr 30.

BACKGROUND: The objective of the study is to examine the reliability of erosion and joint space narrowing scores derived from hand x-rays posted on the Internet compared to scores derived from original plain x-rays.METHODS: Left and right x-rays of...

The structure of tri(cyclohexyl)tin chloride between 108 and 298 K: a compound in which molecular dimensions vary with temperature.

Inorganic chemistry

Asadi A, Eaborn C, Hitchcock PB, Meehan MM, Smith JD.
PMID: 12817973
Inorg Chem. 2003 Jun 30;42(13):4141-6. doi: 10.1021/ic026272f.

Care is necessary when relating physical data obtained at one temperature on compounds showing significant intermolecular interactions to X-ray data obtained at other temperatures. This is revealed by the determination of the structure of tri(cyclohexyl)tin chloride at nine different...

Synthesis of aryl- and heteroaryl[a]pyrrolo[3,4-c]carbazoles.

The Journal of organic chemistry

Sanchez-Martinez C, Faul MM, Shih C, Sullivan KA, Grutsch JL, Cooper JT, Kolis SP.
PMID: 14535777
J Org Chem. 2003 Oct 17;68(21):8008-14. doi: 10.1021/jo034207x.

Synthesis of aryl- and hetero[a]pyrrolo[3,4-c]carbazoles by photochemical oxidation and Heck cyclization are described. Photochemical oxidation of 2-naphthyl indolyl maleimide affords two different carbazole regioisomers, depending on the reaction conditions. The regiochemistry of the cyclization can be controlled using the...

Observing the creation of electronic feshbach resonances in soft x-ray-induced O2 dissociation.

Science (New York, N.Y.)

Sandhu AS, Gagnon E, Santra R, Sharma V, Li W, Ho P, Ranitovic P, Cocke CL, Murnane MM, Kapteyn HC.
PMID: 19008441
Science. 2008 Nov 14;322(5904):1081-5. doi: 10.1126/science.1164498.

When an atom or molecule is ionized by an x-ray, highly excited states can be created that then decay, or autoionize, by ejecting a second electron from the ion. We found that autoionization after soft x-ray photoionization of molecular...

Soft X-ray-driven femtosecond molecular dynamics.

Science (New York, N.Y.)

Gagnon E, Ranitovic P, Tong XM, Cocke CL, Murnane MM, Kapteyn HC, Sandhu AS.
PMID: 17823349
Science. 2007 Sep 07;317(5843):1374-8. doi: 10.1126/science.1144920.

The direct observation of molecular dynamics initiated by x-rays has been hindered to date by the lack of bright femtosecond sources of short-wavelength light. We used soft x-ray beams generated by high-harmonic upconversion of a femtosecond laser to photoionize...

Sedimentation in bidisperse and polydisperse colloids.

Journal of colloid and interface science

Watson AD, Barker GC, Robins MM.
PMID: 15848415
J Colloid Interface Sci. 2005 Jun 01;286(1):176-86. doi: 10.1016/j.jcis.2004.12.053.

We introduce a simple force and flux balance model for sedimentation and creaming in high volume fraction, polydisperse colloidal suspensions. The model is set alongside monodisperse and bidisperse sedimentation data for latex spheres, and we suggest that the broadening...

Cross-phase-modulation nonlinearities and holographic solitons in periodically poled photovoltaic photorefractives.

Optics letters

Cohen O, Murnane MM, Kapteyn HC, Segev M.
PMID: 16599223
Opt Lett. 2006 Apr 01;31(7):954-6. doi: 10.1364/ol.31.000954.

We show that the nonlinearity in periodically poled photovoltaic photorefractives can be solely of the cross-phase-modulation type. The effects of self-phase modulation and asymmetric energy exchange, which exist in homogeneously poled photovoltaic photorefractives, can be considerably suppressed by the...

Gastric feeding as an extension of an established enteral nutrition protocol.

Nutrition in clinical practice : official publication of the American Society for Parenteral and Enteral Nutrition

Marr AB, McQuiggan MM, Kozar R, Moore FA.
PMID: 16215146
Nutr Clin Pract. 2004 Oct;19(5):504-10. doi: 10.1177/0115426504019005504.

BACKGROUND: Indiscriminate gastric feeding in ICU patients imposes unacceptable risks of aspiration. Believing that a subset of ICU patients can be fed safely via the stomach, we have developed a protocol to identify appropriate patients and guide the bedside...

Molecular recollision interferometry in high harmonic generation.

Physical review letters

Zhou X, Lock R, Li W, Wagner N, Murnane MM, Kapteyn HC.
PMID: 18352553
Phys Rev Lett. 2008 Feb 22;100(7):073902. doi: 10.1103/PhysRevLett.100.073902. Epub 2008 Feb 21.

We use extreme-ultraviolet interferometry to measure the phase of high-order harmonic generation from transiently aligned CO(2) molecules. We unambiguously observe a reversal in phase of the high-order harmonic emission for higher harmonic orders with a sufficient degree of alignment....
