Autofluorescent Proteins

2008
Autofluorescent proteins (AFPs) have revolutionized molecular cell biology, and applications continue to harness the power of these genetically encoded fluorescent tags. Here, we review the discovery and physical properties of AFPs as well as their development through mutational optimization for several functional parameters.

AUTOFLUORESCENCE OF CHOROIDAL MELANOMAS

RETINAL Cases & Brief Reports, 2007
To report autofluorescence findings for two patients with choroidal melanomas.Records and photographs for two patients with choroidal melanomas were reviewed. Fundus autofluorescence photography was performed using the Heidelberg confocal SLO system (Heidelberg Retina Angiograph; Heidelberg Engineering, Dossenheim, Germany).Both patients had lipofuscin

Autofluorescence Endoscopy

Gastrointestinal Endoscopy Clinics of North America, 2009
Autofluorescence endoscopy is a wide area imaging technique, with the ability to rapidly examine a large surface area of gastrointestinal mucosa to detect small areas of dysplasia or cancer. It has potential in diseases such as Barrett's esophagus, ulcerative colitis, and gastric cancer, in which large areas of mucosa may harbor areas of dysplasia or ...

Autofluorescence of intraocular tumours

Current Opinion in Ophthalmology, 2013
Fundus autofluorescence is a noninvasive technique for evaluation of intrinsic autofluorescence of the tissues within the eye. In recent years, autofluorescence has become an important diagnostic tool for the assessment of various ocular diseases such as age-related macular degeneration and retinal dystrophies.

Fundus Autofluorescence

2018
Fundus autofluorescence (FAF) imaging is a rapid and noninvasive technique to evaluate retinal pigment epithelial (RPE) function. The predominant source of FAF in the macula is lipofuscin granules.

Laser Applications and Autofluorescence

2020
The diagnostic pathway for oral suspicious lesions usually starts with the clinical examination based on inspection and palpation of the oral mucosa. Such a phase is strongly related to the experience of the operator. Moreover, oral epithelial dysplasia and early oral carcinomas may already be present within areas of macroscopically intact oral mucosa.

On the autofluorescence of aged fingermarks

Forensic Science International, 2016
Fingermark autofluorescence changes with time, both spectrally and in total intensity. In this study we investigate which components in the aged fingermarks cause this change in autofluorescent signal. Thin layer chromatography combined with fluorescence spectroscopy was used to identify fluorescent aging products.

Autofluorescence imaging of pingueculae

British Journal of Ophthalmology, 2008
To analyse the autofluoresence (AF) properties of pingueculae and compare the size of AF with the extent of the visible lesion.Forty eyes of 23 patients with pingueculae were included in the study. AF images were obtained using an HRA2 confocal scanning laser ophthalmoscope; anterior segment photographies were obtained using TRC-50IX, IMAGEnet 2000 ...

Autofluorescence of treated retinoblastoma

Journal of American Association for Pediatric Ophthalmology and Strabismus, 2011
To describe the autofluorescent features of retinoblastomas after treatment.Standard fundus photography and autofluorescence (AF) photography (580 nm excitation, 695 nm barrier filter) were performed on 88 tumors of 61 patients. Clinical features were correlated with autofluorescent features.The mean patient age at AF was 10.3 years.

Fundus Autofluorescence

Fundus autofluorescence (FAF) imaging is a noninvasive and rapid technique to visualize fluorophores in the fundus. The physical principle is based on the excitation of certain molecules by a specific wavelength of light and emission through a longer wavelength.
