Bacterial metabolites influence the autofluorescence of Clostridioides difficile

Frontiers in Microbiology
Clostridioides difficile is a bacterial pathogen that has been implicated in severe gastrointestinal infections. C. difficile has intrinsic green autofluorescence and the level of this autofluorescence is known to be increased by growth time and oxygen ...

Macular pigment density at the site of altered fundus autofluorescence [PDF]

, 2010
The purpose of our study was to determine whether abnormalities of increased or decreased fundus autofluorescence (FAF) are associated with local changes in macular pigment (MP) optical density in patients with age-related maculopathy (ARM) and macular ...

Decreased green autofluorescence in cancerous tissues is a potential biomarker for diagnosis of renal cell carcinomas

Scientific Reports
This study primarily focuses on the potential sources of autofluorescence, including keratins (KRT) encoded by KRT1, KRT7, and KRT8, to investigate their contributions to the differences in autofluorescence between cancerous tissues and adjacent non ...

CEACAM1 participation in breast cancer progression

Molecular Oncology, EarlyView.
In invasive breast cancer (BC), CEACAM1 shifts from an apical to a uniform membranous/cytoplasmic pattern, or is lost, as tumors dedifferentiate, inversely tracking the Ki‐67 proliferative index. In MCF‐7 cells, only CEACAM1‐4L suppresses proliferation, repressing cell cycle and growth factor genes.

Skin autofluorescence in diabetes mellitus [PDF]

, 2008
AGEs ofwel advanced glycation endproducts zijn onomkeerbaar versuikerde stoffen, die voornamelijk aan eiwitten zijn gekoppeld, en die bij ieder mens stapelen. Bij iemand met diabetes mellitus gaat dit proces echter versneld.

Pharmacological chromatin remodeling enhances response to estrogen therapy in ER+ breast cancer

Molecular Oncology, EarlyView.
Estrogen therapy elicits clinical benefit in ~ 30% of patients with endocrine‐resistant estrogen receptor (ER)‐positive breast cancer. Based on findings that ER transcriptional activation underlies response to estrogen therapy, we tested the effects of epigenetic dysregulation via pharmacological inhibition of histone deacetylases (HDACi).

Fundus Autofluorescence Lifetime Patterns in Retinitis Pigmentosa. [PDF]

, 2018
Purpose We investigated whether fundus autofluorescence (FAF) lifetimes in patients with retinitis pigmentosa display a disease-specific lifetime pattern.

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

FEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...
