Nature. 2012 Aug 30;488(7413):603-8. doi: 10.1038/nature11340.

Light-matter interactions are ubiquitous, and underpin a wide range of basic research fields and applied technologies. Although optical interactions have been intensively studied, their microscopic details are often poorly understood and have so far not been directly measurable. X-ray...

Nanoscale Catalysts for NMR Signal Enhancement by Reversible Exchange.

The journal of physical chemistry. C, Nanomaterials and interfaces

Shi F, Coffey AM, Waddell KW, Chekmenev EY, Goodson BM.
PMID: 26185545
J Phys Chem C Nanomater Interfaces. 2015 Apr 02;119(13):7525-7533. doi: 10.1021/acs.jpcc.5b02036.

Two types of nanoscale catalysts were created to explore NMR signal enhancement via reversible exchange (SABRE) at the interface between heterogeneous and homogeneous conditions. Nanoparticle and polymer comb variants were synthesized by covalently tethering Ir-based organometallic catalysts to support...

Missed diagnosis of stroke in the emergency department: a cross-sectional analysis of a large population-based sample.

Diagnosis (Berlin, Germany)

Newman-Toker DE, Moy E, Valente E, Coffey R, Hines AL.
PMID: 28344918
Diagnosis (Berl). 2014 Jun;1(2):155-166. doi: 10.1515/dx-2013-0038. Epub 2014 Apr 03.

BACKGROUND: Some cerebrovascular events are not diagnosed promptly, potentially resulting in death or disability from missed treatments. We sought to estimate the frequency of missed stroke and examine associations with patient, emergency department (ED), and hospital characteristics.METHODS: Cross-sectional analysis...

Oxidative stress, activity behaviour and body mass in captive parrots.

Conservation physiology

Larcombe SD, Tregaskes CA, Coffey J, Stevenson AE, Alexander LG, Arnold KE.
PMID: 27293729
Conserv Physiol. 2015 Oct 20;3(1):cov045. doi: 10.1093/conphys/cov045. eCollection 2015.

Many parrot species are kept in captivity for conservation, but often show poor reproduction, health and survival. These traits are known to be influenced by oxidative stress, the imbalance between the production of reactive oxygen species (ROS) and ability...

Accurate prediction of X-ray pulse properties from a free-electron laser using machine learning.

Free-electron lasers providing ultra-short high-brightness pulses of X-ray radiation have great potential for a wide impact on science, and are a critical element for unravelling the structural dynamics of matter. To fully harness this potential, we must accurately know...

Optimized multiplex immunofluorescence single-cell analysis reveals tuft cell heterogeneity.

JCI insight

McKinley ET, Sui Y, Al-Kofahi Y, Millis BA, Tyska MJ, Roland JT, Santamaria-Pang A, Ohland CL, Jobin C, Franklin JL, Lau KS, Gerdes MJ, Coffey RJ.

JCI Insight. 2017 Jun 02;2(11). doi: 10.1172/jci.insight.93487. eCollection 2017 Jun 02.

Intestinal tuft cells are a rare, poorly understood cell type recently shown to be a critical mediator of type 2 immune response to helminth infection. Here, we present advances in segmentation algorithms and analytical tools for multiplex immunofluorescence (MxIF),...

Rev Sci Instrum. 2014 Aug;85(8):083116. doi: 10.1063/1.4893657.

The advent of few femtosecond x-ray light sources brings promise of x-ray/optical pump-probe experiments that can measure chemical and structural changes in the 10-100 fs time regime. Widely distributed timing systems used at x-ray Free-Electron Laser facilities are typically...
