Autofluorescence in Plants [PDF]

open access: yesMolecules, 2020
Plants contain abundant autofluorescent molecules that can be used for biochemical, physiological, or imaging studies. The two most studied molecules are chlorophyll (orange/red fluorescence) and lignin (blue/green fluorescence). Chlorophyll fluorescence

Time-Since-Deposition Signatures for Canine Blood Based on Cellular Autofluorescence [PDF]

open access: yesVeterinary Sciences
Animal cruelty investigations can be hampered by not knowing when a biological sample was deposited at a crime scene, i.e., the sample’s time-since-deposition (TSD). The goal of this study was to characterize a new signature system for estimating the TSD

Autofluorescence Is a Common Trait in Different Oceanic Fungi

open access: yesJournal of Fungi, 2021
Natural autofluorescence is a widespread phenomenon observed in different types of tissues and organisms. Depending on the origin of the autofluorescence, its intensity can provide insights on the physiological state of an organism.

Evaluation of Autofluorescence in Identifying Parathyroid Glands by Measuring Parathyroid Hormone in Fine-Needle Biopsy Washings

open access: yesFrontiers in Endocrinology, 2022
BackgroundNear-infrared autofluorescence imaging has potentially great value for assisting endocrine surgeons in identifying parathyroid glands and may dramatically change the surgical strategy of endocrine surgeons in thyroid surgery.

Blocking autofluorescence in brain tissues affected by ischemic stroke, hemorrhagic stroke, or traumatic brain injury

open access: yesFrontiers in Immunology, 2023
Autofluorescence is frequently observed in animal tissues, interfering with an experimental analysis and leading to inaccurate results. Sudan black B (SBB) is a staining dye widely used in histological studies to eliminate autofluorescence. In this study,

Fundus autofluorescence imaging

open access: yesProgress in Retinal and Eye Research, 2021
Fundus autofluorescence (FAF) imaging is an in vivo imaging method that allows for topographic mapping of naturally or pathologically occurring intrinsic fluorophores of the ocular fundus. The dominant sources are fluorophores accumulating as lipofuscin in lysosomal storage bodies in postmitotic retinal pigment epithelium cells as well as other ...

Pixel-by-pixel autofluorescence corrected FRET in fluorescence microscopy improves accuracy for samples with spatially varied autofluorescence to signal ratio

open access: yesScientific Reports, 2023
The actual interaction between signaling species in cellular processes is often more important than their expression levels. Förster resonance energy transfer (FRET) is a popular tool for studying molecular interactions, since it is highly sensitive to ...

Feasibility of parathyroid gland autofluorescence imaging after indocyanine green fluorescence angiography

open access: yesFrontiers in Endocrinology, 2023
BackgroundIn thyroid surgery, autofluorescence allows the parathyroid glands (PTGs) to be located very early to protect them. Moreover, indocyanine green (ICG) fluorescence angiography (ICG-FA) allows for assessing the viability of the PTGs and ...

Autofluorescence methods in ophthalmology [PDF]

open access: yesJournal of Biomedical Optics, 2004
An overview of the fluorophores of the eye, the methods used to measure ocular fluorescence, and the existing or ready-to-market instrumentation for the early diagnosis and monitoring of ophthalmic pathologies is presented. Emphasis is given to the impact that a more detailed knowledge of the fluorophores of the eye, their age and pathology ...
