(12.) Mehrotra R, Singh M, Thomas S, Nair P, Pandya S, Nigam NS, Shukla P:Cross-sectional study evaluating chemiluminescence and autofluorescence
in the detection of clinically innocuous precancerous and cancerous oral lesions.
Excluding the control group of 30 patients 15 males and 15 females (mean age=37.5yrs) among the remaining 62 patients 22 of those who showed loss of fluorescence on tissue fluorescence imaging only 19 patients showed histopathological presence of neoplastic changes (mild/moderate/ severe dysplasia CIS and well differentiated OSCC) concluding the sensitivity of autofluorescence
(VELscope) for the detection of dysplastic lesions to be 86% and its specificity in detecting neoplastic lesions and diagnosing oral potentially malignant disorders and benign lesions to be 74%.

Immunohistochemistry is far more frequently used than fluorescence for routine in situ detection of proteins in histopathology, and it has advantages, such as less dependence on expensive instrumentation and the avoidance of autofluorescence
problems, as well as compatibility with standard histologic stains.
imaging is a "broad-based imaging tool" that can monitor changes in the pattern of distribution of autofluorescent proteins in the esophagus when normal mucosal tissue becomes dysplastic or cancerous, Dr.
The instrument combines an autofluorescence
light source and camera already approved in Europe for diagnostic bronchoscopy with a 1.3-mm diameter ductoscope.
The authors found that the area of autofluorescence
in this population declined with age, which they believe indicated the nature of CAFP in representing recent cumulative exposure to ocular UV radiation as opposed to lifetime cumulative exposure.
contributes to false-positive intracellular Foxp3 staining in macrophages: a lesson learned from flow cytometry.
images were recorded at a wavelength of 488 nm via [greater than or equal to]500 nm barrier filter.
According to the ophthalmological examination protocol, all patients were subjected to visual acuity test using Snellen chart; ocular tension measurement using Goldmann applanation tonometer; biomicroscopic examination; central 10-degree visual field test using Octopus 900 (Interzeag AG, Schlieren-Zurich, Switzerland); fundus autofluorescence
photography and color fundus photograph examination using Visucam NM/FA (Carl Zeiss, Germany), and macular RGC-IPL thickness and peripapillary retinal nerve fiber layer (RNFL) thickness measurements using Cirrus high-definition OCT, model 5000 (Carl Zeiss Meditec Inc., Jena, Germany).
