Physiology in conservation translocations.

Conservation physiology

Tarszisz E, Dickman CR, Munn AJ.
PMID: 27293675
Conserv Physiol. 2014 Dec 17;2(1):cou054. doi: 10.1093/conphys/cou054. eCollection 2014.

Conservation translocations aim to restore species to their indigenous ranges, protect populations from threats and/or reinstate ecosystem functions. They are particularly important for the conservation and management of rare and threatened species. Despite tremendous efforts and advancement in recent...

Sensitivity of laser speckle contrast imaging to flow perturbations in the cortex.

Biomedical optics express

Davis MA, Gagnon L, Boas DA, Dunn AK.
PMID: 27231587
Biomed Opt Express. 2016 Feb 03;7(3):759-75. doi: 10.1364/BOE.7.000759. eCollection 2016 Mar 01.

Laser speckle contrast imaging has become a ubiquitous tool for imaging blood flow in a variety of tissues. However, due to its widefield imaging nature, the measured speckle contrast is a depth integrated quantity and interpretation of baseline values...

Two-color multiphoton .

Light, science & applications

Perillo EP, Jarrett JW, Liu YL, Hassan A, Fernée DC, Goldak JR, Bonteanu A, Spence DJ, Yeh HC, Dunn AK.
PMID: 29576887
Light Sci Appl. 2017;6. doi: 10.1038/lsa.2017.95. Epub 2017 Nov 17.

Two-color multiphoton microscopy through wavelength mixing of synchronized lasers has been shown to increase the spectral window of excitable fluorophores without the need for wavelength tuning. However, most currently available dual output laser sources rely on the costly and...

The effects of industry sponsorship on comparator selection in trial registrations for neuropsychiatric conditions in children.

PloS one

Dunn AG, Mandl KD, Coiera E, Bourgeois FT.
PMID: 24376857
PLoS One. 2013 Dec 23;8(12):e84951. doi: 10.1371/journal.pone.0084951. eCollection 2013.

Pediatric populations continue to be understudied in clinical drug trials despite the increasing use of pharmacotherapy in children, particularly with psychotropic drugs. Most pertinent to the clinical selection of drug interventions are trials directly comparing drugs against other drugs....

Femtosecond laser inscription of Bragg grating waveguides in bulk diamond.

Optics letters

Bharadwaj V, Courvoisier A, Fernandez TT, Ramponi R, Galzerano G, Nunn J, Booth MJ, Osellame R, Eaton SM, Salter PS.
PMID: 28957060
Opt Lett. 2017 Sep 01;42(17):3451-3453. doi: 10.1364/OL.42.003451.

Femtosecond laser writing is applied to form Bragg grating waveguides in the diamond bulk. Type II waveguides are integrated with a single pulse point-by-point periodic laser modification positioned toward the edge of the waveguide core. These photonic devices, operating...

Cavity-Enhanced Room-Temperature Broadband Raman Memory.

Physical review letters

Saunders DJ, Munns JH, Champion TF, Qiu C, Kaczmarek KT, Poem E, Ledingham PM, Walmsley IA, Nunn J.
PMID: 26991164
Phys Rev Lett. 2016 Mar 04;116(9):090501. doi: 10.1103/PhysRevLett.116.090501. Epub 2016 Mar 03.

Broadband quantum memories hold great promise as multiplexing elements in future photonic quantum information protocols. Alkali-vapor Raman memories combine high-bandwidth storage, on-demand readout, and operation at room temperature without collisional fluorescence noise. However, previous implementations have required large control...

Spinal Manipulative Therapy for Chronic Lower Back Pain in Older Veterans: A Prospective, Randomized, Placebo-Controlled Trial.

Geriatric orthopaedic surgery & rehabilitation

Dougherty PE, Karuza J, Dunn AS, Savino D, Katz P.
PMID: 26246937
Geriatr Orthop Surg Rehabil. 2014 Dec;5(4):154-64. doi: 10.1177/2151458514544956.

INTRODUCTION: Chronic lower back pain (CLBP) is problematic in older veterans. Spinal manipulative therapy (SMT) is commonly utilized for CLBP in older adults, yet there are few randomized placebo-controlled trials evaluating SMT.METHODS: The purpose of the study was to...

Flux or speed? Examining speckle contrast imaging of vascular flows.

Biomedical optics express

Kazmi SM, Faraji E, Davis MA, Huang YY, Zhang XJ, Dunn AK.
PMID: 26203384
Biomed Opt Express. 2015 Jun 18;6(7):2588-608. doi: 10.1364/BOE.6.002588. eCollection 2015 Jul 01.

Speckle contrast imaging enables rapid mapping of relative blood flow distributions using camera detection of back-scattered laser light. However, speckle derived flow measures deviate from direct measurements of erythrocyte speeds by 47 ± 15% (n = 13 mice) in...
