Proton pumping activity and photocycle kinetics.

, 2014
(a) Light induced proton fluxes in E. coli vesicles containing wild type and mutant GR. Initial pH values were adjusted to7. The buffering capacity was calibrated and the pH changes were recalculated into proton concentrations. (b) Photocycle kinetics of

Searching for a photocycle of the cryptochrome photoreceptors [PDF]

Current Opinion in Plant Biology, 2010
The initial photochemistry of plant cryptochromes has been extensively investigated in recent years. It is hypothesized that cryptochrome photoexcitation involves a Trp-triad-dependent photoreduction. According to this hypothesis, cryptochromes in the resting state contain oxidized FAD; light triggers a sequential electron transfer from three ...

Photocyclization of styrylpyrazines.

Chemical and Pharmaceutical Bulletin, 1979
Irradiation of several 2-(β-arylvinyl) pyrazines at room temperature using a high pressure mercury lamp afforded aza-phenanthrenes in moderate yields. The ring closure of 2-[β-(3-pyridyl) vinyl] pyrazine (IIIb) occurred only at the 4-position of the pyridine ring, whereas 2-[β-(2-naphthyl) vinyl] pyrazine (IIIe) cyclized at the 1-position of the ...

Effects of paraprobiotic Lactobacillus acidophilus LA‐5 on PANoptosis, oxidative stress and inflammation in acetic acid‐induced ulcerative colitis

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Ulcerative colitis (UC) is a relapsing inflammatory bowel disease characterised by oxidative stress, inflammation and regulated cell death of the colonic mucosa. Because live probiotics may cause bacteraemia and sepsis in immunocompromised hosts, non‐viable (paraprobiotic) alternatives have attracted interest.

Interrelations of M‐intermediates in bacteriorhodopsin photocycle [PDF]

FEBS Letters, 1992
The photocycles of the wild‐type bacteriorhodopsin and the D96N mutant were investigated by the flash‐photolysis technique. The M‐intermediate formation (400 nm) and the L‐intermediate decay (520 nm) were found to be well described by a sum of two exponents (time constants, τ1 = 65 and τ2 = 250 μs) for the wild‐type bR and three exponents (τ1 = 55 μs ...

Azobenzene‐based molecular solar thermal integrated with phase change materials for smart thermoregulating textiles

Responsive Materials, EarlyView.
This work introduces azobenzene (azo)‐based molecular solar thermal energy storage systems with phase change materials (PCM): molecular engineering toward smart textiles. Integrating Azo with PCM, the fabric captures solar energy and ambient heat concurrently.

Photocycle populations with femtosecond excitation of crystalline photoactive yellow protein [PDF]

, 2016
We investigate photocycle excitation of crystalline photoactive yellow protein using femtosecond laser pulses. This work establishes the feasibility and suitable optical excitation conditions to perform femtosecond time resolved X-ray crystallographic ...

Stable flies preferentially oviposit on sites offering conspecific eggs with egg‐derived bacterial semiochemicals

Insect Science, EarlyView.
Stable flies preferentially oviposit on sites offering conspecific eggs with egg‐derived airborne semiochemicals. Egg‐borne bacterial symbionts, and Serratia marcescens in particular, produce odorants which attract gravid female flies and elicit oviposition.

Photoexcitation of the P₄⁴⁸⁰ State Induces a Secondary Photocycle That Potentially Desensitizes Channelrhodopsin‑2 [PDF]

, 2018
Channelrhodopsins (ChRs) are light-gated cation channels. In spite of their wide use to activate neurons with light, the photocurrents of ChRs rapidly decay in intensity under both continuous illumination and fast trains of light pulses, broadly referred
