Polarized light scattering spectroscopy for quantitative measurement of epithelial cellular structures in situ

Autor: Kamran Badizadegan, Rajan Gurjar, Lev T. Perelman, Vadim Backman, Michael S. Feld, R. R. Dasari, Irving Itzkan

Publikováno v: IEEE Journal of Selected Topics in Quantum Electronics. 5:1019-1026

We report an in situ method of probing the structure of living epithelial cells, based on light scattering spectroscopy with polarized light. The method makes it possible to distinguish between single backscattering from uppermost epithelial cells an

Publikováno v: Physical Review Letters. 66:1681-1684

Using laser-induced nuclear-orientation and optical-saturation techniques, we have produced sub-Doppler changes in the anisotropy of the angular distribution of the 514-keV {gamma} rays from the 1-{mu}s isomer {sup 85}Rb{sup {ital m}}. This permits h

Quantification of (7S,8R)-dihydroxy-(9R,10S)-epoxy-7,8,9,10-tetrahydrobenzo[a]pyrene adducts in human serum albumin by laser-induced fluorescence: implications for the in vivo metabolism of benzo[a]pyrene

Autor: C C, Ozbal, P L, Skipper, M C, Yu, S J, London, R R, Dasari, S R, Tannenbaum

Publikováno v: Cancer epidemiology, biomarkersprevention : a publication of the American Association for Cancer Research, cosponsored by the American Society of Preventive Oncology. 9(7)

The ubiquitous environmental carcinogen benzo[a]pyrene (BaP) is metabolized in vivo in humans to its ultimate carcinogenic form of 7,8-dihydroxy-9,10-epoxy-7,8,9,10-tetrahydrobenzo[a]pyrene (BPDE). Mouse skin tumorigenicity studies indicate that the

Analysis of nucleotides and aromatic amino acids in normal and neoplastic colon mucosa by ultraviolet resonance raman spectroscopy

Autor: N N, Boustany, J M, Crawford, R, Manoharan, R R, Dasari, M S, Feld

Publikováno v: Laboratory investigation; a journal of technical methods and pathology. 79(10)

The objective of this study was to explore the potential of using ultraviolet resonance Raman (UVRR) spectroscopy to analyze normal and neoplastic colon tissue. Ultraviolet light at 251 nm, generated from the third harmonic of a Titanium:Sapphire las

Near-infrared fluorescence spectroscopy detects Alzheimer's disease in vitro

Autor: E B, Hanlon, I, Itzkan, R R, Dasari, M S, Feld, R J, Ferrante, A C, McKee, D, Lathi, N W, Kowall

Publikováno v: Photochemistry and photobiology. 70(2)

The purpose of this study was to investigate whether near-infrared (NIR) fluorescence spectroscopy could be used to detect Alzheimer's disease (AD) by brain tissue autofluorescence. Unfixed temporal cortex specimens from AD cases and age-matched, non

Density of Photon Paths in Turbid Medium for Short Times of Flight

Autor: R. R. Dasari, Michael S. Feld, Lev T. Perelman, Joshua N. Winn, Jun Wu, Kun Chen

Publikováno v: Advances in Optical Imaging and Photon Migration.

The major obstacle to employing laser-based methods for imaging disease inside the body is the turbidity of biological tissue [1].
