Equivalence of background and bleaching desensitization in isolated rod photoreceptors of the larval tiger salamander. [PDF]

open access: yes, 1996
Psychophysical experiments have shown an equivalence between sensitivity reduction by background light and by bleaches for the human scotopic system.

Climate change promotes parasitism in a coral symbiosis. [PDF]

open access: yes, 2018
Coastal oceans are increasingly eutrophic, warm and acidic through the addition of anthropogenic nitrogen and carbon, respectively. Among the most sensitive taxa to these changes are scleractinian corals, which engineer the most biodiverse ecosystems on ...

Controlled Aggregation of Pyrene‐Based Supramolecular Nanostructures for Light‐Driven Switchable H2 or H2O2 Production

open access: yesAdvanced Functional Materials, EarlyView.
This work reports the self‐assembly of a pyrene derivative into two distinct nanostructures and their application in visible‐light photocatalysis. The two nanostructures exhibit completely different yet complementary photocatalytic activities, promoting either H2 or H2O2 evolution.

Efficacy of 1.23% Acidulate Phosphate Fluoride Gel on Tooth Sensitivity during Home Bleaching Treatment

open access: yesمجله دانشکده دندانپزشکی اصفهان
One of the side effects of dental home bleaching is hypersensitivity.This study aimed to assess the efficacy of the application of 1.23% acidulated phosphate fluoride (APF) gel before/after daily home bleaching with carbamide ...

CFP and YFP photostabilities are differentially affected by common mounting fluids [PDF]

open access: yes, 2010
The use of spectrally distinct variants of green fluorescent protein (GFP) such as cyan or yellow mutants (CFP and YFP, respectively) is very common in all different fields of life sciences, e.g.

Mechanically and Chemically Defined PEG Hydrogels Improve Reproducibility in Human Cardioid Development

open access: yesAdvanced Healthcare Materials, EarlyView.
Synthetic matrix metalloproteinase (MMP)‐degradable polyethylene glycol (PEG)‐based hydrogels are developed to investigate the influence of mechanical and biochemical cues on cardioid development. Matrix stiffness and cell adhesion motifs significantly regulate cardioid formation, chamber morphogenesis, contractile function, and cardioid transcriptome.

A novel paleo-bleaching proxy using boron isotopes and high-resolution laser ablation to reconstruct coral bleaching events [PDF]

open access: yesBiogeosciences, 2015
Coral reefs occupy only ~ 0.1 percent of the ocean's habitat, but are the most biologically diverse marine ecosystem. In recent decades, coral reefs have experienced a significant global decline due to a variety of causes, one of the major causes being ...

Persistent activation of transducin by bleached rhodopsin in salamander rods. [PDF]

open access: yes, 1996
The hydrolysis-resistant GTP analogue GTP-gamma-S was introduced into rods isolated from the retina of the salamander Ambystoma tigrinum to study the origin of the persistent excitation induced by intense bleaching illumination.
