No difference in pain reduction after epidural steroid injections in diabetic versus nondiabetic patients: A retrospective cohort study.

Journal of anaesthesiology, clinical pharmacology

Wong F, Namdari B, Dupler S, Kovac MF, Makarova N, Dalton JE, Turan A.
PMID: 27006548
J Anaesthesiol Clin Pharmacol. 2016 Jan-Mar;32(1):84-8. doi: 10.4103/0970-9185.173334.

BACKGROUND AND AIMS: Diabetes affects peripheral and central neurons causing paresthesia, allodynia, hyperalgesia, and spontaneous pain. However, the effect of diabetes on response to epidural steroid injection (ESI) remains unknown. We hypothesized that diabetic patients receiving ESI will have...

A Modified Reverse One-Hybrid Screen Identifies Transcriptional Activation Domains in PHYTOCHROME-INTERACTING FACTOR 3.

Frontiers in plant science

Dalton JC, Bätz U, Liu J, Curie GL, Quail PH.
PMID: 27379152
Front Plant Sci. 2016 Jun 17;7:881. doi: 10.3389/fpls.2016.00881. eCollection 2016.

Transcriptional activation domains (TADs) are difficult to predict and identify, since they are not conserved and have little consensus. Here, we describe a yeast-based screening method that is able to identify individual amino acid residues involved in transcriptional activation...

Finite-size scaling in silver nanowire films: design considerations for practical devices.

Nanoscale

Large MJ, Cann M, Ogilvie SP, King AA, Jurewicz I, Dalton AB.
PMID: 27377048
Nanoscale. 2016 Jul 14;8(28):13701-7. doi: 10.1039/c6nr03960j.

We report the first application of finite-size scaling theory to nanostructured percolating networks, using silver nanowire (AgNW) films as a model system for experiment and simulation. AgNWs have been shown to be a prime candidate for replacing Indium Tin...

Preparative semiconductor photoredox catalysis: An emerging theme in organic synthesis.

Beilstein journal of organic chemistry

Manley DW, Walton JC.
PMID: 26664577
Beilstein J Org Chem. 2015 Sep 09;11:1570-82. doi: 10.3762/bjoc.11.173. eCollection 2015.

Heterogeneous semiconductor photoredox catalysis (SCPC), particularly with TiO2, is evolving to provide radically new synthetic applications. In this review we describe how photoactivated SCPCs can either (i) interact with a precursor that donates an electron to the semiconductor thus...

Absolute Rate Constants for the Reactions of Primary Alkyl Radicals with Aromatic Amines(1).

The Journal of organic chemistry

Burton A, Ingold KU, Walton JC.
PMID: 11667229
J Org Chem. 1996 May 31;61(11):3778-3782. doi: 10.1021/jo952162x.

Hydrogen abstraction from diarylamines (4-X-C(6)H(4))(2)NH [X = H, CH(3), C(8)H(17), CH(3)O, and Br] by the 2-methyl-2-phenylpropyl radical in n-dodecane solution was investigated by thermolysis of 3-methyl-3-phenylbutanoyl peroxide in the presence of various concentrations of the amines. The reaction is...

Silylated cyclohexadienes as new radical chain reducing reagents: preparative and mechanistic aspects.

Journal of the American Chemical Society

Studer A, Amrein S, Schleth F, Schulte T, Walton JC.
PMID: 12733911
J Am Chem Soc. 2003 May 14;125(19):5726-33. doi: 10.1021/ja0341743.

Various silylated 1,4-cyclohexadienes are presented as superior tin hydride substitutes for the conduction of various radical chain reductions. Debrominations, deiodinations, and deselenations can be performed using these environmentally benign reagents. Furthermore, Barton-McCombie-type deoxygenations using silylated cyclohexadienes are described. Radical...

Effect of sometribove administration on LH concentration in dairy cattle.

Theriogenology

Dalton JC, Marcinkowski DP.
PMID: 16727401
Theriogenology. 1994 Feb;41(2):437-45. doi: 10.1016/0093-691x(94)90079-x.

Sixteen lactating, normally cycling Holstein cows were used to study 1) the effects of sometribove (recombinant methionyl bST) administration on basal LH concentrations and 2) the pituitary response to a GnRH challenge during the breeding period. The cows received...

Kinetic and theoretical study of 4-exo ring closures of carbamoyl radicals onto C=C and C=N bonds.

Organic letters

Dilabio GA, Scanlan EM, Walton JC.
PMID: 15625001
Org Lett. 2005 Jan 06;7(1):155-8. doi: 10.1021/ol047716+.

Carbamoyl radicals were generated from oxime oxalate amides, and the kinetics of their 4-exo cyclizations onto C=C and C=NO bonds, leading to beta-lactam-containing species, were studied by EPR spectroscopy. DFT computations with model carbamoyl radicals predicted 4-exo ring closures...

Radical-carbanion cyclo-coupling in armed aromatics: overriding steric hindrance to ring closure.

Chemical communications (Cambridge, England)

Roydhouse MD, Walton JC.
PMID: 16136248
Chem Commun (Camb). 2005 Sep 21;(35):4453-5. doi: 10.1039/b506391d. Epub 2005 Aug 04.

Omega-(2-Halophenyl)alkyl-2-oxazolines were prepared and reacted via base promoted intramolecular coupling of radical with carbanionic centres to yield 1-phenyl-1-oxazolino-indan and -tetralin derivatives containing quaternary C-atoms.

Axial and equatorial cyclohexylacyl and tetrahydropyranyl-2-acyl radicals. An experimental and theoretical study.

Organic letters

DiLabio GA, Ingold KU, Roydhouse MD, Walton JC.
PMID: 15524473
Org Lett. 2004 Nov 11;6(23):4319-22. doi: 10.1021/ol0481683.

Axial and equatorial cyclohexylacyl and tetrahydropyranyl-2-acyl radicals gave distinct EPR spectra thanks to surprisingly large beta-hydrogen atom hyperfine splittings that enabled them to be characterized and monitored. DFT computations indicated that the axial species (X = CH(2)) had a...

Digestion of haemoglobin by schistosomes: 35 years on.

Parasitology today (Personal ed.)

Dalton JP, Smith AM, Clough KA, Brindley PJ.
PMID: 15275329
Parasitol Today. 1995 Aug;11(8):299-303. doi: 10.1016/0169-4758(95)80045-x.

Adult schistosomes obtain nutrients by digesting haemoglobin, which they obtain from ingested host red blood cells. Here John Dalton, Angela Smith, Karen Clough and Paul Brindley argue that a cathepsin L proteinase recently identified in their laboratory as the...
