Journal ArticleDOI
Ytterbium-doped silica fiber lasers: versatile sources for the 1-1.2 /spl mu/m region
Helen M. Pask,Robert Carman,D.C. Hanna,Anne C. Tropper,C.J. Mackechnie,Paul R. Barber,Judith M. Dawes +6 more
TL;DR: Ytterbium-doped silica fibers exhibit very broad absorption and emission bands, from /spl sim/800 nm to /spl sim/1064 nm for absorption and /spl S sim/970 nm to/spl sim s sim/1200 nm for emission as discussed by the authors.
Journal ArticleDOI
Use of the mouse aortic ring assay to study angiogenesis
Marianne Baker,Stephen D. Robinson,Tanguy Lechertier,Paul R. Barber,Bernardo Tavora,Gabriela D'Amico,Dylan T. Jones,Boris Vojnovic,Kairbaan Hodivala-Dilke +8 more
TL;DR: The aortic ring assay allows analysis of cellular proliferation, migration, tube formation, microvessel branching, perivascular recruitment and remodeling—all without the need for cellular dissociation—thus providing a more complete picture of angiogenic processes compared with traditional cell-based assays.
Journal Article
Mechanisms associated with tumor vascular shut-down induced by combretastatin A-4 phosphate: intravital microscopy and measurement of vascular permeability.
Gillian M. Tozer,Vivien E. Prise,John T. Wilson,Maja Cemazar,Siqing Shan,Mark W. Dewhirst,Paul R. Barber,Borivoj Vojnovic,David J. Chaplin +8 more
TL;DR: The tumor vascular effects of the tubulin destabilizing agent disodium combretastatinA-4 3-O-phosphate (CA-4-P) were investigated in the rat P22 tumor growing in a dorsal skin flap window chamber implanted into BD9 rats, and results suggest a mechanism of action of CA- 4-P in vivo.
Journal ArticleDOI
Lifetime quenching in Yb-doped fibres
TL;DR: In this paper, it was shown that the excited state lifetime of a fraction of the Yb ions (between 1% and over 90%) is quenched to a very small value, leading to a strong unbleachable loss.
Journal ArticleDOI
Intravital imaging of tumour vascular networks using multi-photon fluorescence microscopy.
Gillian M. Tozer,Simon Ameer-Beg,Jennifer H.E. Baker,Paul R. Barber,Sally A. Hill,Richard J. Hodgkiss,R J Locke,Vivien E. Prise,Ian D. Wilson,Borivoj Vojnovic +9 more
TL;DR: Intravital microscopy of tumours growing in 'window chambers' in animal models provides a means of directly investigating tumour angiogenesis and vascular response to treatment, in terms of both the morphology of blood vessel networks and the function of individual vessels.
