Determination of the low concentration correction in the macroscopic singlet oxygen model for PDT.

Proceedings of SPIE--the International Society for Optical Engineering

Kim MM, Penjweini R, Finlay JC, Zhu TC.
PMID: 27053824
Proc SPIE Int Soc Opt Eng. 2015 Mar 17;9694:96940D. doi: 10.1117/12.2213417.

The macroscopic singlet oxygen model has been used for singlet oxygen explicit dosimetry in photodynamic therapy (PDT). The photophysical parameters for commonly used sensitizers, HPPH and BPD, have been investigated in pre-clinical studies using mouse models. So far, studies...

An IR Navigation System for Pleural PDT.

Frontiers in physics

Zhu TC, Liang X, Kim MM, Finlay JC, Dimofte A, Rodriguez C, Simone CB, Friedberg JS, Cengel KA.
PMID: 25995987
Front Phys. 2015 Mar;3. doi: 10.3389/fphy.2015.00009.

Pleural photodynamic therapy (PDT) has been used as an adjuvant treatment with lung-sparing surgical treatment for malignant pleural mesothelioma (MPM). In the current pleural PDT protocol, a moving fiber-based point source is used to deliver the light. The light...

Prophylactic antibiotics for children with recurrent urinary tract infections.

Paediatrics & child health

Robinson JL, Finlay JC, Lang ME, Bortolussi R.
PMID: 25722643
Paediatr Child Health. 2015 Jan-Feb;20(1):45-51. doi: 10.1093/pch/20.1.45.

Prophylactic antibiotics for urinary tract infections are no longer routinely recommended. A large number of children must be given prophylaxis to prevent one infection and antibiotic resistance is a major concern when treating community-acquired urinary tract infections. The results...

Optimization of physiological parameter for macroscopic modeling of reacted singlet oxygen concentration in an .

Proceedings of SPIE--the International Society for Optical Engineering

Wang KK, Busch TM, Finlay JC, Zhu TC.
PMID: 25995531
Proc SPIE Int Soc Opt Eng. 2009 Feb 18;7164:71640O. doi: 10.1117/12.809024.

Macroscopic singlet oxygen model incorporating photobleaching as an input parameter.

Proceedings of SPIE--the International Society for Optical Engineering

Kim MM, Finlay JC, Zhu TC.
PMID: 25914795
Proc SPIE Int Soc Opt Eng. 2015 Mar 02;9308:93080V. doi: 10.1117/12.2079046.

A macroscopic singlet oxygen model for photodynamic therapy (PDT) has been used extensively to calculate the reacted singlet oxygen concentration for various photosensitizers. The four photophysical parameters (ξ, σ, β, δ) and threshold singlet oxygen dose ([

Proceedings of SPIE--the International Society for Optical Engineering

Finlay JC, Zhu TC, Dimofte A, Stripp D, Malkowicz SB, Whittington R, Miles J, Glatstein E, Hahn SM.
PMID: 26136613
Proc SPIE Int Soc Opt Eng. 2005 Apr 22;5689:299-310. doi: 10.1117/12.590709.

Among the challenges to the clinical implementation of photodynamic therapy (PDT) is the delivery of a uniform photodynamic dose to induce uniform damage to the target tissue. As the photodynamic dose depends on both the local sensitizer concentration and...

Study of light fluence rate distribution in photodynamic therapy using finite-element method.

Proceedings of SPIE--the International Society for Optical Engineering

Li J, Zhu TC, Finlay JC.
PMID: 26113755
Proc SPIE Int Soc Opt Eng. 2006 Jan 21;6139. doi: 10.1117/12.646251.

In photodynamic therapy (PDT), it is desirable to determine the light fluence distribution accurately for treatment planning. Earlier studies have shown heterogeneous distribution of optical properties in patients' prostates. Finiteelement method (FEM) is suitable for dealing with heterogeneous media...

Zhu TC, Li J, Finlay JC, Dimofte A, Stripp D, Malkowicz BS, Hahn SM.
PMID: 26113758
Proc SPIE Int Soc Opt Eng. 2006 Jan 21;6139. doi: 10.1117/12.646220.

We report results of in-vivo light dosimetry of light fluence (rate) in human prostate during photodynamic therapy (PDT). Measurements were made in-vivo at the treatment wavelength (732nm) in 15 patients in three to four quadrants using isotropic detectors placed...

Kostant polynomials and the cohomology ring for G/B.

Proceedings of the National Academy of Sciences of the United States of America

Billey SC.
PMID: 11038536
Proc Natl Acad Sci U S A. 1997 Jan 07;94(1):29-32. doi: 10.1073/pnas.94.1.29.

The Schubert calculus for G/B can be completely determined by a certain matrix related to the Kostant polynomials introduced in section 5 of Bernstein, Gelfand, and Gelfand [Bernstein, I., Gelfand, I. & Gelfand, S. (1973) Russ. Math. Surv. 28,...

Development of the Eagle-Barrett (prune belly) syndrome and a thickened, poorly functional bladder wall after early second-trimester decompression of fetal megacystis.

Ultrasound in obstetrics & gynecology : the official journal of the International Society of Ultrasound in Obstetrics and Gynecology

Finley BE, Bennett TL, Burlbaw J, Levitch L.

Ultrasound Obstet Gynecol. 1993 Jul 01;3(4):284-6. doi: 10.1046/j.1469-0705.1993.03040284.x.

The management of bladder outlet obstruction in the fetus remains a debated issue. Recent data suggest the use of cystocentesis for the possible relief of the bladder neck obstruction or for the opening of posterior urethral valves. This case...

Equatorially dominated magnetic field change at the surface of Earth's core.

Slow temporal variations in Earth's magnetic field originate in the liquid outer core. We analyzed the evolution of nonaxisymmetric magnetic flux at the core surface over the past 400 years. We found that the most robust feature is westward...

Earth's magnetic field has decayed by about 5% per century since measurements began in 1840. Directional measurements predate those of intensity by more than 250 years, and we combined the global model of directions with paleomagnetic intensity measurements to...
