Measuring couplings in crowded NMR spectra: pure shift NMR with multiplet analysis.

Chemical communications (Cambridge, England)

Foroozandeh M, Adams RW, Kiraly P, Nilsson M, Morris GA.
PMID: 26343867
Chem Commun (Camb). 2015 Oct 28;51(84):15410-3. doi: 10.1039/c5cc06293d.

The PSYCHE method for pure shift NMR is exploited to generate 2D J spectra with full decoupling in one dimension and multiplet structure in the other, allowing spin-spin coupling constants to be measured even in very crowded spectra. Significant...

(Z)-oxacyclotridec-10-en-2-one does not appear to be responsible for resistance to adult alfalfa weevil feeding exhibited byMedicago rugosa.

Journal of chemical ecology

Doss RP, Johnson KJ.
PMID: 24258804
J Chem Ecol. 1991 Mar;17(3):535-42. doi: 10.1007/BF00982124.

Steam distillate prepared from leaves ofMedicago rugosa Desr. could inhibit feeding by adult alfalfa weevils (Hypera postica (Gyll.) on membrane filters, whereas an equivalent amount of steam distillate prepared usingM. sativa L. had no effect on weevil feeding. Earlier...

Matrix-assisted diffusion-ordered spectroscopy: choosing a matrix.

Magnetic resonance in chemistry : MRC

Gramosa NV, Ricardo NMSP, Adams RW, Morris GA, Nilsson M.
PMID: 27272403
Magn Reson Chem. 2016 Oct;54(10):815-820. doi: 10.1002/mrc.4459. Epub 2016 Jun 07.

Diffusion-ordered spectroscopy (DOSY) is an important technique for separating the NMR signals of the components in a mixture, and relies on differences in diffusion coefficient. Standard DOSY experiments therefore struggle when the components of a mixture are of similar...

Vitamin D Receptor Expression in Vitiligo.

Indian journal of dermatology

Doss RW, El-Rifaie AA, Gohary YM, Rashed LA.
PMID: 26677265
Indian J Dermatol. 2015 Nov-Dec;60(6):544-8. doi: 10.4103/0019-5154.169123.

BACKGROUND: Vitiligo is a progressive depigmenting disorder characterized by loss of functional melanocytes from the epidermis. The etiopathogenesis of vitiligo is still unclear. Vitamin D has stimulatory effects on melanocytes and acts through its nuclear Vitamin D receptor (VDR)...

Heat Shock Protein-70 Expression in Vitiligo and its Relation to the Disease Activity.

Indian journal of dermatology

Doss RW, El-Rifaie AA, Abdel-Wahab AM, Gohary YM, Rashed LA.
PMID: 27512186
Indian J Dermatol. 2016 Jul-Aug;61(4):408-12. doi: 10.4103/0019-5154.185704.

BACKGROUND: Vitiligo is a progressive depigmenting disorder characterized by the loss of functional melanocytes from the epidermis. The etiopathogenesis of vitiligo is still unclear. Heat shock proteins (HSPs) are prime candidates to connect stress to the skin. HSPs were...

Feasibility study on the characterization of thin layers by charged-particle activation analysis.

Analytical chemistry

De Neve K, Strijckmans K, Dams R.
PMID: 10905312
Anal Chem. 2000 Jul 01;72(13):2814-20. doi: 10.1021/ac000187c.

The purpose of this feasibility study was to investigate the possibilities and limitations of Charged-Particle Activation Analysis (CPAA) as a thin layer characterization method, i.e., the determination of the mass thickness or the composition of a thin layer. Therefore...

Deeply Penetrating Banded Zonal Flows in the Solar Convection Zone.

The Astrophysical journal

Howe R, Christensen-Dalsgaard J, Hill F, Komm RW, Larsen RM, Schou J, Thompson MJ, Toomre J.
PMID: 10770715
Astrophys J. 2000 Apr 20;533(2):L163-L166. doi: 10.1086/312623.

Helioseismic observations have detected small temporal variations of the rotation rate below the solar surface that correspond to the so-called "torsional oscillations" known from Doppler measurements of the surface. These appear as bands of slower- and faster-than-average rotation moving...

Dynamic variations at the base of the solar convection zone.

Science (New York, N.Y.)

Howe R, Christensen-Dalsgaard J, Hill F, Komm RW, Larsen RM, Schou J, Thompson MJ, Toomre J.
PMID: 10741959
Science. 2000 Mar 31;287(5462):2456-60. doi: 10.1126/science.287.5462.2456.

We have detected changes in the rotation of the sun near the base of its convective envelope, including a prominent variation with a period of 1.3 years at low latitudes. Such helioseismic probing of the deep solar interior has...

Non-spectral interferences encountered with a commercially available high resolution ICP-mass spectrometer.

Analytical and bioanalytical chemistry

Vanhaecke F, Riondato J, Moens L, Dams R.
PMID: 15045425
Anal Bioanal Chem. 1996 Jun;355(3):397-400. doi: 10.1007/s0021663550397.

Results of a systematic study concerning non-spectral interferences observed with a commercially available high resolution ICP-mass spectrometer are reported and compared to observations made with a quadrupole-based instrument. In general, matrix effects were observed to be to a large...
