Autofluorescence Is a Common Trait in Different Oceanic Fungi

Journal 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

Frontiers 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.

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

Scientific 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 ...

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

Frontiers 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,

Feasibility of parathyroid gland autofluorescence imaging after indocyanine green fluorescence angiography

Frontiers 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 ...

The fuss over lipo“fuss”cin: not all autofluorescence is the same

European Journal of Histochemistry, 2015
Since the first description of cellular autofluorescence over a century ago, we have now come to appreciate that autofluorescence should not be discarded as a biological artifact but embraced as a biological phenomenon with potentially important cellular

Fundus autofluorescence in detection of embolus in retinal artery occlusion

Indian Journal of Ophthalmology. Case Reports, 2022
Fundus autofluorescence (FAF) is a noninvasive imaging tool helpful in various retinal and choroidal diseases. In this series, we report the utility of FAF in two cases of retinal artery occlusion (RAO).

Identification of 5-hydroxytryptamine-producing cells by detection of fluorescence in paraffin-embedded tissue sections

European Journal of Histochemistry, 2016
5-Hydroxytryptamine (5-HT) produced by enterochromaffin (EC) cells is an important enteric mucosal signaling ligand and has been implicated in several gastrointestinal diseases, including inflammatory bowel disease and functional disorders such as ...
