SAPHO syndrome--a pictorial assay.

The Iowa orthopaedic journal

Khanna L, El-Khoury GY.
PMID: 23576940
Iowa Orthop J. 2012;32:189-95.

SAPHO (synovitis, acne, pustulosis, hyperostosis and osteitis) syndrome is a distinct clinical entity representing involvement of the musculoskeletal and dermatologic systems. It is well known to rheumatologists because of characteristic skin manifestations and polyarthropathy. However, few reports exist in...

Case Rep Ophthalmol. 2017 Apr 28;8(1):279-287. doi: 10.1159/000471789. eCollection 2017.

PURPOSE: To describe the technique of limbal stem cell-sparing corneoscleroplasty for the management of advanced keratoglobus.METHODS: A patient with bilateral advanced keratoglobus, with best-corrected visual acuity of 20/400 in the right eye and 20/200 in the left eye, underwent...

Enhanced Raman scattering from aromatic dithiols electrosprayed into plasmonic nanojunctions.

Faraday discussions

Faraday Discuss. 2015;184:339-57. doi: 10.1039/c5fd00036j. Epub 2015 Sep 25.

We describe surface enhanced Raman spectroscopy (SERS) experiments in which molecular coverage is systematically varied from 3.8 × 10(5) to 3.8 × 10(2) to 0.38 molecules per μm(2) using electrospray deposition of ethanolic 4,4'-dimercaptostilbene (DMS) solutions. The plasmonic SERS...

Tip-enhanced Raman nanographs: mapping topography and local electric fields.

Nano letters

El-Khoury PZ, Gong Y, Abellan P, Arey BW, Joly AG, Hu D, Evans JE, Browning ND, Hess WP.
PMID: 25741776
Nano Lett. 2015 Apr 08;15(4):2385-90. doi: 10.1021/acs.nanolett.5b00609. Epub 2015 Mar 09.

We report tip-enhanced Raman imaging experiments in which information on sample topography and local electric fields is simultaneously obtained using an all-optical detection scheme. We demonstrate how a Raman-active 4,4'-dimercaptostilbene (DMS)-coated gold tip of an atomic force microscope can...

Time domain simulations of chemical bonding effects in surface-enhanced spectroscopy.

The Journal of chemical physics

El-Khoury PZ, Bylaska EJ, Hess WP.
PMID: 24206294
J Chem Phys. 2013 Nov 07;139(17):174303. doi: 10.1063/1.4827455.

The atom-centered density-matrix propagation method is used to illustrate how time-dependent conformational changes affect the electronic structure and derived spectroscopic properties of a prototypical finite metal cluster-bound π-conjugated organic complex, Ag7-benzenethiol. We establish that there is considerable conformational flexibility...

Vibronic Raman scattering at the quantum limit of plasmons.

Nano letters

PMID: 24926797
Nano Lett. 2014 Jul 09;14(7):4114-8. doi: 10.1021/nl501690u. Epub 2014 Jun 17.

We record sequences of Raman spectra at a plasmonic junction formed by a gold AFM tip in contact with a silver surface coated with 4,4'-dimercaptostilbene (DMS). A 2D correlation analysis of the recorded trajectories reveals that the observable vibrational...

Cognitive disorders such as postoperative cognitive dysfunction, confusion, and delirium, are common following anesthesia in the elderly, with symptoms persisting for months or years in some patients. Alzheimer's disease (AD) patients appear to be particularly at risk of cognitive...

Microglial scavenger receptors and their roles in the pathogenesis of Alzheimer's disease.

In the title compound, C21H19BrN2O2·C2H6OS, the indole ring system is essentially planar, with a maximum deviation of 0.050 (3) Å for the non-bridgehead C atom adjacent to the N atom. The two cyclo-hex-2-enone rings adopt half-chair conformations. An intra-molecular...
