Testing BR photocycle kinetics

Biophysical Journal, 1995
An improved K absorption spectrum in the visible is obtained from previous photocycle data for the D96N mutant of bacteriorhodopsin, and the previously obtained M absorption spectrum in the visible and the fraction cycling are confirmed at 25 degrees C. Data at lower temperatures are consistent with negligible temperature dependence in the spectra from

Synchrony within Aβ mechanoreceptor subtypes governs signal propagation to primary somatosensory cortex

The Journal of Physiology, EarlyView.
Abstract figure legend We used an optogenetic gain‐of‐function manipulation to investigate how sensory signals from two subtypes of Aβ low threshold mechanoreceptors (LTMRs) contribute to the cortical representation of touch. CatCh, a sensitive and fast channelrhodopsin variant, enables pulsed‐light generation of high‐frequency action potential trains ...

Arguments for an additional long-lived intermediate in the photocycle of the full-length aureochrome 1c receptor: A time-resolved small-angle X-ray scattering study

Structural Dynamics, 2019
Aureochromes (AUREO) act as blue-light photoreceptors in algae. They consist of a light-, oxygen-, voltage-sensitive (LOV) domain and a DNA-binding basic region/leucine zipper.

Natural Born Laser Dyes: Excited-State Intramolecular Proton Transfer (ESIPT) Emitters and Their Use in Random Lasing Studies

Nanomaterials, 2019
A series of five excited-state intramolecular proton transfer (ESIPT) emitters based on a 2-(2′-hydroxyphenyl) benzoxazole (HBO) scaffold, functionalized with a mono-or bis-(trialkylsilyl) acetylene extended spacer are presented.

Caloric restriction and aerobic exercise differentially counteract muscle–tendon dysfunction following diet‐induced obesity in C57BL/6J mice

The Journal of Physiology, EarlyView.
Abstract figure legend Diet‐induced obesity induced fibro‐adipogenic remodelling of the muscle–tendon unit, characterized by increased fibrosis, reduced specific force, impaired relaxation kinetics, elevated hysteresis, and reduced aerobic capacity and glucose tolerance.

Ultrafast infrared spectroscopy reveals a key step for successful entry into the photocycle for photoactive yellow protein

, 2006
Photoactive proteins such as PYP (photoactive yellow protein) are generally accepted as model systems for studying protein signal state formation. PYP is a blue-light sensor from the bacterium Halorhodospira halophila.

Effect of Halogen Ions on the Photocycle of Fluorescent Carbon Nanodots

C, 2019
Carbon dots (C-dots) are well-known for their strong sensitivity to the environment, which reflects on intensity and shape changes of their fluorescence, induced by various interacting ions and molecules in solution. Although these interactions have been

β‐hydroxy‐β‐methylbutyrate improves fast‐twitch muscle function, histopathology and mitochondrial respiration in the D2.mdx dystrophic mouse

The Journal of Physiology, EarlyView.
Abstract figure legend β‐Hydroxy‐β‐methylbutyrate (HMB) enhances fast‐twitch muscle and mitochondrial function in D2.mdx mice. Male DBA/2J (wild‐type) and D2.mdx mice aged 3 or 6 months received daily β‐hydroxy‐β‐methylbutyrate (HMB; 1 mg g−1 day−1) via drinking water for 8 weeks. Fast‐twitch extensor digitorum longus (EDL) and slow‐twitch soleus (SOL)
