Soil Chemical and Physical Properties Associated with Suppression of Take-all of Wheat by Trichoderma koningii.

Phytopathology

Duffy BK, Ownley BH, Weller DM.
PMID: 18945008
Phytopathology. 1997 Nov;87(11):1118-24. doi: 10.1094/PHYTO.1997.87.11.1118.

ABSTRACT Trichoderma koningii, originally isolated from a take-all-suppressive soil in Western Australia, has been shown to protect wheat against take-all disease and increase grain yield in field trials in Australia, China, and the United States. However, within a region,...

Optical frequency shifter technique based on stimulated Brillouin scattering in birefringent optical fiber.

Applied optics

Duffy CJ, Tatam RP.
PMID: 20856421
Appl Opt. 1993 Oct 20;32(30):5966-72. doi: 10.1364/AO.32.005966.

An optical technique for producing a heterodyne carrier frequency suitable for electronic signalprocessing schemes in sensing applications is described. The technique exploits stimulated Brillouin scattering (SBS) generated in birefringent optical fiber. Systems based on single-fiber and dual-fiber topologies are...

The nature of methadone diversion in England: a Merseyside case study.

Harm reduction journal

Duffy P, Baldwin H.
PMID: 22243982
Harm Reduct J. 2012 Jan 13;9:3. doi: 10.1186/1477-7517-9-3.

BACKGROUND: Methadone maintenance treatment (MMT) is a key element in treatment for opiate addiction; however concerns about the diversion of methadone remain. More current empirical data on methadone diversion are required. This research investigated the market for diverted methadone...

Measurement properties of questionnaires assessing complementary and alternative medicine use in pediatrics: a systematic review.

PloS one

Toupin April K, Moher D, Stinson J, Byrne A, White M, Boon H, Duffy CM, Rader T, Vohra S, Tugwell P.
PMID: 22768098
PLoS One. 2012;7(6):e39611. doi: 10.1371/journal.pone.0039611. Epub 2012 Jun 29.

OBJECTIVE: Complementary and alternative medicine (CAM) is commonly used by children, but estimates of that use vary widely partly due to the range of questionnaires used to assess CAM use. However, no studies have attempted to appraise measurement properties...

Nitrogen dioxide inside and outside 137 homes and implications for ambient air quality standards and health effects research.

Environmental science & technology

Serialized holography for brand protection and authentication.

Applied optics

Vather D, Naydenova I, Cody D, Zawadzka M, Martin S, Mihaylova E, Curran S, Duffy P, Portillo J, Connell D, McDonnell S, Toal V.
PMID: 30117909
Appl Opt. 2018 Aug 01;57(22):E131-E137. doi: 10.1364/AO.57.00E131.

The problems presented by counterfeit products and documentation are discussed. Limitations of existing holograms for anti-counterfeit applications are described. We describe the advantages of full holographic serialization and the requirements in terms of materials and techniques for mass production...

Microglial Immune Response to Low Concentrations of Combustion-Generated Nanoparticles: An In Vitro Model of Brain Health.

Nanomaterials (Basel, Switzerland)

Duffy CM, Swanson J, Northrop W, Nixon JP, Butterick TA.
PMID: 29522448
Nanomaterials (Basel). 2018 Mar 09;8(3). doi: 10.3390/nano8030155.

The brain is the central regulator for integration and control of responses to environmental cues. Previous studies suggest that air pollution may directly impact brain health by triggering the onset of chronic neuroinflammation. We hypothesize that nanoparticle components of...

Monte Carlo simulation of complex spectra for opacity calculations.

Physical review. A, Atomic, molecular, and optical physics

Bauche J, Bauche-Arnoult C, Duffy P, Klapisch M.
PMID: 9906633
Phys Rev A. 1991 Nov 01;44(9):5715-5724. doi: 10.1103/physreva.44.5715.

Clinical and psychosocial stress factors are associated with decline in physical activity over time in children with juvenile idiopathic arthritis.

Pediatric rheumatology online journal

Heale LD, Houghton KM, Rezaei E, Baxter-Jones ADG, Tupper SM, Muhajarine N, Benseler SM, Boire G, Cabral DA, Campillo S, Chédeville G, Chetaille AL, Dancey P, Duffy C, Duffy KW, Ellsworth J, Guzman J, Huber AM, Jurencak R, Lang B, Laxer RM, Morishita K, Oen KG, Petty RE, Ramsey SE, Roth J, Schneider R, Scuccimarri R, Spiegel L, Stringer E, Tse SML, Tucker LB, Turvey SE, Yeung RSM, Rosenberg AM.

Pediatr Rheumatol Online J. 2021 Jun 29;19(1):97. doi: 10.1186/s12969-021-00584-4.

BACKGROUND: Physical activity (PA) patterns in children with juvenile idiopathic arthritis (JIA) over time are not well described. The aim of this study was to describe associations of physical activity (PA) with disease activity, function, pain, and psychosocial stress...

The full dynamics of energy relaxation in large organic molecules: from photo-excitation to solvent heating.

Chemical science

Balevičius V, Wei T, Di Tommaso D, Abramavicius D, Hauer J, Polívka T, Duffy CDP.
PMID: 31183032
Chem Sci. 2019 Apr 02;10(18):4792-4804. doi: 10.1039/c9sc00410f. eCollection 2019 May 14.

In some molecular systems, such as nucleobases, polyenes or the active ingredients of sunscreens, substantial amounts of photo-excitation energy are dissipated on a sub-picosecond time scale, raising questions such as: where does this energy go or among which degrees...

Characterized by a rapidly increasing prevalence, elevated mortality and rehospitalization rates, and inadequacy of pharmaceutical therapies, heart failure with preserved ejection fraction (HFpEF) has motivated the widespread development of device-based solutions. HFpEF is a multifactorial disease of various etiologies...
