Photobleaching by Spectralis Fixation Target [PDF]
JAMA Ophthalmology, 2016 The aim of this study is to determine whether the cross-shaped fixation target in a spectral-domain optical coherence tomography instrument (Spectralis; Heidelberg Engineering) could produce a cross-shaped increase fundus autofluorescence artifact on subsequent imaging.Thirty eyes of 15 healthy volunteers (8 women and 7 men; mean [SD] age 24 [3] years)

Fluorescent Membrane Probes Based on a Coumarin-Thiazole Scaffold
Acta Chimica Slovenica, 2019 Biological functions of cell membranes and their correlation to the heterogeneity of the latter’s lipid composition are still poorly understood. Fluorescence provides one of the most versatile tools for studying biological membranes.

Sensors, 2020 Fluorescein, and derivatives of fluorescein, are often used as fluorescent probes and sensors. In systems where pH is a variable, protonation/deprotonation of the molecule can influence the pertinent photophysics.

Factors influencing Barley Stripe Mosaic Virus-mediated gene silencing in wheat [PDF]
, 2010 Virus induced gene silencing (VIGS) is a technology that has been used primarily to target the virus genome in infected plants. However, if the virus genome carries inserts derived from the host plant, the system could be employed to target the mRNAs ...

Journal of Marine Science and Engineering, 2020 Photodegradation is a natural process that strongly affects the chromophoric fraction of dissolved organic matter (DOM), especially in surface water of the oceans. In the euphotic zone, the concentration and quality of DOM are mostly dependent on primary

Unbreakable codes in electrospun fibers : digitally encoded polymers to stop medicine counterfeiting [PDF]
, 2010 Fluorescent polymer solutions can easily be electrospun into micrometer-sized fibers and subsequently encoded with long lasting digital codes by a photobleaching process.

Evaluating performance in three-dimensional fluorescence microscopy [PDF]
, 2007 In biological fluorescence microscopy, image contrast is often degraded by a high background arising from out of focus regions of the specimen. This background can be greatly reduced or eliminated by several modes of thick specimen microscopy, including ...

A pharmacological cocktail for arresting actin dynamics in living cells. [PDF]
, 2011 The actin cytoskeleton is regulated by factors that influence polymer assembly, disassembly, and network rearrangement. Drugs that inhibit these events have been used to test the role of actin dynamics in a wide range of cellular processes.

A petunia ethylene-responsive element binding factor, PhERF2, plays an important role in antiviral RNA silencing. [PDF]
, 2016 Virus-induced RNA silencing is involved in plant antiviral defense and requires key enzyme components, including RNA-dependent RNA polymerases (RDRs), Dicer-like RNase III enzymes (DCLs), and Argonaute proteins (AGOs).
