Microneedles rollers as a potential device to increase ALA diffusion and PpIX production: Evaluations by wide-field fluorescence imaging and fluorescence spectroscopy
(2014-01-01)
One of the limitations of topical photodynamic therapy (PDT) using 5-aminolevulinic acid (ALA) is the poor ability to penetrate biological barriers of skin and the recurrence rates in treatments. This study aimed to identify ...
Microneedles rollers as a potential device to increase ALA diffusion and PpIX production: evaluations by wide-field fluorescence imaging and fluorescence spectroscopy
(International Society for Optical Engineering - SPIEBellingham, 2014)
One of the limitations of topical photodynamic therapy (PDT) using 5-aminolevulinic acid (ALA) is the poor ability to penetrate biological barriers of skin and the recurrence rates in treatments. This study aimed to identify ...
Fluorescence Level of Composites Assessed by Computer Processing of Digital Images - ScanWhite
(2012)
The human dentition is naturally translucent, opalescent and fluorescent. Differences between the level of fluorescence of tooth structure and restorative materials may result in distinct metameric properties and consequently ...
Imaging amyloid precursor protein in vivo: An axonal transport assay
(Humana Press, 2012-08)
Fusion of fluorescent probes to axonally transported proteins represents an established approach that enables live imaging of axonal transport. In this approach, in vivo examination of fluorescent particle dynamics provides ...
Relationship between DAPI-fluorescence fading and nuclear DNA content: An alternative method to DNA quantification?
(Sociedad de Biología de Chile, 2007)
A novel algorithm for detection of tuberculosis bacilli in sputum smear fluorescence images
(Institute of Advanced Engineering and Science, 2020)
This work proposes an algorithm aimed at recognizing and accounting Koch bacilli in digital images of microbiological sputum samples stained with auramine, in order to determine the degree of concentration and the state ...
A systematic study on fluorescence contrast in near infrared diffuse transmittance imaging with indocyanine green
(N I R Publications, 2019-06-25)
Near infrared fluorescence imaging is a sensitive, noninvasive technique for diagnostic applications in biomedical optics. The main purpose of this work is thus to explore how to improve the contrast of images obtained by ...
Efficacy of photodynamic therapy against larvae of Aedes aegypti: confocal microscopy and fluorescence-lifetime imaging
(International Society for Optical Engineering - SPIEBellingham, 2014)
Recently a few demonstration on the use of Photodynamic Reaction as possibility to eliminate larvae that transmit diseases for men has been successfully demonstrated. This promising tool cannot be vastly used due to many ...
Fluorescence Fluctuations and Equivalence Classes of Ca2+ Imaging Experiments
(Public Library Of Science, 2014-04)
Ca2z release into the cytosol through inositol 1,4,5-trisphosphate receptors (IP3Rs) plays a relevant role in numerous physiological processes. IP3R-mediated Ca2z signals involve Ca2z-induced Ca2z-release (CICR) whereby ...
